holding that similar common questions met the commonality 20 requirement
How later courts described this case
- holding that similar common questions met the commonality 20 requirement
- “Rule 23(b)(3) requires a showing that questions common to the class 14 predominate, not that those questions will be answered, on the merits, in favor of the class.”
- “In order to 11 satisfy the predominance requirement, the plaintiff need not prove the existence of the defect.”
- “[B]ecause the class does not exclude purchasers who have 8 already received refunds through Maybelline's Refund program, it is overbroad and not 9 ascertainable.”

6 I. Background
7 A. Factual Background
8 Plaintiff Terry Hamm is an owner of a Mercedes-Benz vehicle equipped with an allegedly
9 defective automatic transmission known as the 722.9 7G-Tronic transmission. Second Amended
10 Complaint (“SAC”) ¶ 1, Dkt. No. 34. Hamm purchased his used Mercedes-Benz 2006 CLK350
11 vehicle in December 2012 from Stevens Creek Toyota in San Jose, California. Def.’s Separate
12 Statement of Undisputed Facts In Supp. of Mot. for Summ. J. Fact 2. At the time of Hamm’s
13 purchase, Stevens Creek Toyota was a Toyota dealership (i.e., not a Mercedes-Benz dealership).
14 Id. Fact 3. Hamm is the fourth owner of the used Mercedes-Benz 2006 CLK350 vehicle. Id. Fact.
15 1.
16 The alleged transmission defect typically manifests itself outside the 4 year/50,000 mile
17 duration of MBUSA’s New Vehicle Limited Warranty. SAC ¶ 1. The alleged defect causes
18 Mercedes-Benz vehicles with the 722.9 transmission to enter “limp mode” in which their vehicles
19 cannot shift or accelerate. Id. Hamm’s transmission failed by exhibiting the defect at issue: his
20 vehicle locked into low gear, was unable to accelerate, and the Check Engine Light was
21 illuminated. Decl. of Roy A. Katriel In Opp’n To Mot. For Summ. J. (“Katriel Decl.”) Ex. 2
22 (Hamm Dep. at 132:12-135:2). Hamm paid for a replacement of the transmission’s conductor
23 plate and reprogramming of its valve body at a cost of $1,051.18. Id. Ex. 7 (Hamm repair invoice).
24 Hamm points to warranty claims relating to the 722.9 transmissions as well as MBUSA’s
25 “repair kits,” remedying issues affecting various 722.9 transmissions, as evidence of the alleged

27 ORDER DENYING MOTION FOR CLASS CERTIFICATION; DENYING MBUSA’S
MOTION TO STRIKE EXPERT REPORT OF D.C. SHARP AND MOTION TO STRIKE
1 defect. Motion at 2–3. Hamm alleges that MBUSA knew of the defect but failed to disclose it,
2 thereby violating the California Consumer Legal Remedies Act (“CLRA”) and the California
3 Unfair Competition Law (“UCL”). Id. ¶¶ 33–35, 37–39. Hamm seeks to represent a class of
4 California owners and lessees of Mercedes vehicles equipped with the 722.9 transmission, seeking
5 damages under the theory that all California purchasers of the class vehicles paid more for their
6 car, that had an undisclosed defect, than they would have paid had the defect not been present or
7 been disclosed prior to the vehicles’ sale. SAC ¶¶ 1, 45.
8 B. Proposed Classes
9 Plaintiff Hamm seeks to certify the following class:
10 All California owners and lessees of Mercedes-Benz vehicles
equipped with the 722.9 7G Tronic transmission. Excluded from this
11 Class definition are all employees, officers, or agents of Defendant
Mercedes-Benz USA, LLC (“MBUSA”). Also excluded from this
12 Class definition are all judicial officers assigned to this case as well
as their staff and immediate families.
13
14 Motion at 1. In the alternative, Plaintiff Hamm seeks the certification of a narrower class defined
15 as:
16 All California owners and lessees of Mercedes-Benz vehicles
equipped with the VGS1 generation of the 722.9 7G Tronic
17 transmission (which were equipped on the 2004-2007 Mercedes
model year vehicles outfitted with the 722.9 7G Tronic transmission).
18 Excluded from this Class definition are all employees, officers, or
agents of MBUSA. Also excluded from this Class definition are all
19 judicial officers assigned to this case as well as their staff and
immediate families.”1
20
21
22
1 There exists a factual dispute as to which iteration of the 722.9 transmission is outfitted on
23 Hamm’s Mercedes-Benz 2006 CLK350 vehicle. Hamm maintains that his vehicle is equipped
with the VGS1 iteration of the 722.9 transmission. Motion at 8. In contrast, MBUSA contends that
24 Hamm’s vehicle is actually outfitted with the VGS2 iteration of the 722.9 transmission. Resp. at
15. To the extent that Hamm’s vehicle is not equipped with the VGS1 iteration of the 722.9
25 transmission, there cannot be a VGS1 subclass represented by Hamm. See Sali v. Corona Reg’l
Med. Ctr., 909 F.3d 996, 1007 (9th Cir. 2018) (“A named plaintiff must be a member of the class
26 she seeks to represent.”).

MOTION TO STRIKE EXPERT REPORT OF D.C. SHARP AND MOTION TO STRIKE
1 Id.
2 As Hamm provides in his Motion, “[e]xcluded from both definitions are all persons who
3 claim personal injuries resulting from the defect alleged in this action. Both definitions also are
4 limited to natural persons.” Id.
5 II. Discussion
6 The Court begins with analyzing the requirements for class certification under Rule 23(a).
7 Afterwards, the Court examines class certification requirements under Rule 23(b)(3). Ultimately,
8 because the Court finds that Hamm will be unable to show that predominance exists under Rule
9 23(b)(3), Hamm is also unable to meet all of the requirements of Rule 23(a), namely typicality, for
10 the same reasons that defeat predominance under Rule 23(b)(3). Finally, the Court turns its
11 attention to three Daubert motions, two from MBUSA to strike the reports of Plaintiff’s experts
12 D.C. Sharp and Murat Okcuoglu, and one from Plaintiff Hamm to strike MBUSA’s expert report
13 of Kevin Keller.
14 A. Motion for Class Certification
15 A motion for a class action may be certified under Rule 23 of the Federal Rules of Civil
16 Procedure if all of the requirements of Rule 23(a) are met and plaintiffs demonstrate that one
17 requirement under Rule 23(b) is also satisfied. Rule 23(a) requires that a plaintiff seeking to assert
18 claims on behalf of a class demonstrate: 1) numerosity; 2) commonality; (3) typicality; and (4) fair
19 and adequate representation of the interests of the class; and 5) ascertainability. Fed. R. Civ. P.
20 23(a); see also In re Yahoo Mail Litig., 308 F.R.D. 577, 596 (N.D. Cal. 2015) (“[A]part from the
21 explicit requirements of Rule 23(a), the party seeking class certification must demonstrate that an
22 identifiable and ascertainable class exists.” (quotation omitted)). Rule 23(b)(3) allows a class
23 action to be maintained where “the court finds that the questions of law or fact common to class
24 members predominate over any questions affecting only individual members, and that a class
25 action is superior to other available methods for fairly and efficiently adjudicating the
26
CASE NO.: 5:16-CV-03370-EJD
27 ORDER DENYING MOTION FOR CLASS CERTIFICATION; DENYING MBUSA’S
MOTION TO STRIKE EXPERT REPORT OF D.C. SHARP AND MOTION TO STRIKE
1 controversy.” Fed. R. Civ. P. 23(b)(3). “An individual question is one where ‘members of a
2 proposed class will need to present evidence that varies from member to member,’ while a
3 common question is one where ‘the same evidence will suffice for each member to make a prima
4 facie showing [or] the issue is susceptible to generalized, classwide proof.’” Tyson Foods, Inc. v.
5 Bouaphakeo, 136 S.Ct. 1036, 1045, 194 L.Ed.2d 124 (2016) (quoting 2 W. Rubenstein, Newberg
6 on Class Actions § 4:50, pp. 196–197 (5th ed. 2012) (internal quotation marks omitted)).
7 i. Rule 23(a)
8 1. Numerosity
9 Rule 23(a)(1) requires that the size of the proposed class be “so numerous that joinder of
10 all the class members is impracticable.” Fed. R. Civ. P. 23(a)(1). In general, Hamm alleges that the
11 putative class suffered an injury at the point of purchasing certain MBUSA vehicles due to
12 MBUSA’s nondisclosure of a transmission defect. Motion at 4. Plaintiff asserts that numerosity is
13 met here as “tens of thousands of Mercedes vehicles equipped with the 722.9 transmission were
14 sold in California.” Id at 6. Further, as Plaintiff additionally points out, the number of MBUSA
15 vehicles with allegedly defective transmissions would still number in the thousands under either of
16 Plaintiff’s two proffered class definitions. Id.
17 MBUSA does not dispute Plaintiff’s contention as to the quantity of MBUSA vehicles sold
18 in California with 722.9 transmissions. As such, this Court is satisfied that the numerosity
19 requirement is met.
20 2. Commonality
21 Commonality under Rule 23(a)(2) mandates that there be “questions of law or fact
22 common to the class.” Fed. R. Civ. P. 23(a)(2). “To satisfy the commonality requirement, a
23 plaintiff must show that the class members have suffered ‘the same injury,’ meaning that class
24 members’ claims must ‘depend upon a common contention’ of such a nature that ‘determination of
25 its truth or falsity will resolve an issue that is central to the validity of each [claim] in one stroke.’”

1 Philips v. Ford Motor Co., 2016 WL 7428810, at *7 (N.D. Cal. Dec. 22, 2016), aff’d, 726 F.
2 App’x 608 (9th Cir. 2018) (quoting Wal-Mart Stores, Inc. v. Dukes, 564 U.S. 338, 350, 131 S. Ct.
3 2541, 2551, 180 L. Ed. 2d 374 (2011)). In addition to “the raising of common questions,” a
4 plaintiff must demonstrate “the capacity of a class-wide proceeding to generate
5 common answers apt to drive the resolution of the litigation.” Wal-Mart, 564 U.S. at 350 (quoting
6 Richard A. Nagareda, Class Certification in the Age of Aggregate Proof, 84 N.Y.U. L. Rev. 97,
7 131–32 (2009)). A plaintiff’s “common contention need not be one that will be answered, on the
8 merits, in favor of the class.” Alcantar v. Hobart Serv., 800 F.3d 1047, 1053 (9th Cir. 2015)
9 (internal quotation marks omitted). Further, “for purposes of Rule 23(a)(2), even a single common
10 question will do.” Dukes, 564 U.S. at 359 (alteration and quotation marks omitted).
11 Here, Plaintiff Hamm has alleged that the 722.9 transmission in all class vehicles suffer
12 from a common defect. “In automobile defect cases, commonality is often found when the most
13 significant question concerns the existence of a defect.” Philips, 2016 WL 7428810, at *7 (quoting
14 Parkinson v. Hyundai Motor Am., 258 F.R.D. 580 (C.D. Cal. 2008)). Hamm has presented a
15 number of issues pertaining to the alleged defect that are common to the class: the existence of a
16 defect, whether MBUSA knew of the alleged defect, whether MBUSA had a duty to disclose its
17 knowledge of the alleged defect to the public, whether MBUSA breached that duty, and whether
18 the failures to disclose were material. Motion at 13; see id. (citing Chamberlan v. Ford Motor Co.,
19 402 F.3d 952, 962 (9th Cir. 2005) (holding that similar common questions met the commonality
20 requirement)).
21 When establishing commonality, “[t]he existence of shared legal issues with divergent
22 factual predicates is sufficient.” Philips, 2016 WL 7428810, at *7 (quoting Hanlon v. Chrysler
23 Corp., 150 F.3d 1011, 1019 (9th Cir. 1998)). Because Hamm has asserted that class members
24 suffered the same injury, namely that the entire class was harmed at the point of purchase by
25 paying more for their Mercedes-Benz vehicle than they would had they known it was equipped

MOTION TO STRIKE EXPERT REPORT OF D.C. SHARP AND MOTION TO STRIKE
1 with a defective transmission, answers to common issues Hamm posits will provide answers
2 common to the class. As such, the Court finds that common issues such as the existence of a
3 defect and MBUSA’s knowledge of the defect are enough to meet “the relatively ‘minimal’
4 showing required to establish commonality.” Ries v. Ariz. Beverages USA LLC, 287 F.R.D. 523,
5 537 (N.D. Cal. 2012) (citing Hanlon, 150 F.3d at 1020).2
6 3. Typicality
7 Rule 23(a)(3) requires that “the claims or defenses of the representative parties [be] typical
8 of the claims or defenses of the class.” Fed. R. Civ. P. 23(a)(3). “Under the rule’s permissive
9 standards, representative claims are ‘typical’ if they are reasonably co-extensive with those of
10 absent class members; they need not be substantially identical.” Hanlon, 150 F.3d at 1020. Class
11 certification is inappropriate, however, if a putative class representative is subject to “unique
12 defenses which threaten to become the focus of the litigation.” Hanon v. Dataproducts Corp., 976
13 F.2d 497, 508 (9th Cir. 1992) (quoting Gary Plastic Packaging Corp. v. Merrill Lynch, Pierce,
14 Fenner & Smith, Inc., 903 F.2d 176, 180 (2d Cir. 1990)).
15 Here, MBUSA argues that Hamm’s claims are atypical because Hamm owns only one of
16 the many iterations of the 722.9 transmissions represented throughout the putative class. Def.’s
17 Resp. in Opp’n to Pl.’s Mot. for Class Certification at 21, Dkt. No. 100 (“Resp.”). However,
18 Hamm’s theory of liability is that all of the 722.9 transmissions are defective, regardless of the
19 specific iteration of the 722.9 transmission. Motion at 1. Hamm’s legal theory asserted on his
20 behalf and on the behalf of the putative class does not differ based on which iteration of the 722.9
21 transmission is present in a class vehicle. Motion at 6–7. Because Hamm’s claim “need not be
22 substantially identical” to the putative class, the Court finds that Hamm’s ownership of only one
23 of the multiple iterations of the 722.9 transmissions to be “reasonably co-extensive with” and thus
24
25
2 Although Hamm meets the commonality requirement under Rule 23(a)(2), he fails to show that
26 common issues will predominate under Rule 23(b)(3), as discussed later in this Order.

27 ORDER DENYING MOTION FOR CLASS CERTIFICATION; DENYING MBUSA’S
MOTION TO STRIKE EXPERT REPORT OF D.C. SHARP AND MOTION TO STRIKE
1 typical to the putative class. Hanlon, 150 F.3d at 1020.
2 MBUSA next contends that Hamm does not meet the Rule 23 typicality requirement
3 because he is subject to unique defenses. Resp. at 20; see also Hanon, 976 F.2d at 508; Blair v.
4 RMC Lonestar, 29 F.3d 630 (9th Cir. 1994) (“If [plaintiff’s] claims were subject to unique
5 defenses, class certification should not have been granted because their claims would have failed
6 the typicality requirement.”); Hoexter v. Simmons, 140 F.R.D. 416, 422–23 (D. Ariz. 1991)
7 (holding that because named plaintiffs are “subject to unique defenses…these plaintiffs’ claims are
8 not typical of the claims of other class members”); Rolex Emps. Ret. Tr. v. Mentor Graphics
9 Corp., 136 F.R.D. 658, 664 (D. Or. 1991) (“The certification of a class is questionable where it is
10 predictable that a major focus of the litigation will be on an arguable defense unique to the named
11 plaintiff or to a subclass.”). Specifically, MBUSA argues Hamm’s theory of reliance may be
12 atypical to those of the putative class because Hamm “purchased his 7-year old used vehicle from
13 a Toyota dealership without ever interacting with MBUSA or reviewing any materials from it; he
14 only glanced at unaffiliated third-party websites.” Id. In contrast, some other members of the
15 putative class may have interacted with MBUSA and reviewed MBUSA’s materials regarding
16 their class vehicle. Because of this, MBUSA argues Hamm’s awareness of any potential disclosure
17 by MBUSA of the alleged defect may differ from the class members he seeks to represent. As
18 discussed further below under the Rule 23(b)(3) predominance analysis, because Hamm is unable
19 to use common evidence to infer reliance across the class, the Court finds that Hamm may be
20 subject to unique defenses that would render his claims atypical to those of the class. Thus,
21 typicality under Rule 23(a) is not met.
22 4. Fair and Adequate Representation of the Class
23 The adequacy analysis under Rule 23(a)(4) requires that the class representatives “fairly
24 and adequately protect the interests of the class.” Fed. R. Civ. P. 23(a)(4). Determining whether
25 the named plaintiff will fairly and “adequately represent a class involves two inquiries: (1)
26
CASE NO.: 5:16-CV-03370-EJD
27 ORDER DENYING MOTION FOR CLASS CERTIFICATION; DENYING MBUSA’S
MOTION TO STRIKE EXPERT REPORT OF D.C. SHARP AND MOTION TO STRIKE
1 whether the named plaintiff and his or her counsel have any conflicts of interest with other class
2 members and (2) whether the named plaintiff and his or her counsel will act vigorously on behalf
3 of the class.” Calvert v. Red Robin Int'l, Inc., 2012 WL 1668980, at *2 (N.D. Cal. May 11, 2012)
4 (citing Lerwill v. Inflight Motion Pictures, Inc., 582 F.2d 507, 512 (9th Cir. 1978)).
5 Here, the Court finds that Plaintiff’s counsel has experience in prosecuting consumer
6 protection actions involving claims similar to those in the instant case. See Katriel Decl. ¶ 14, Ex.
7 13 (firm resume of Katriel Law Firm, P.C.); id. ¶ 15, Ex. 14 (firm resume of Kantrowitz
8 Goldhammer & Graifman, P.C). Plaintiff’s counsel has vigorously litigated this case from its
9 inception, and MBUSA does not contend that Plaintiff’s counsel will not continue to do so.
10 Further, there are no allegations present that Plaintiff’s counsel has any conflicts of interests with
11 any members of the putative class. Thus, the Court finds that Plaintiff’s counsel meets the
12 adequacy requirement.
13 Turning to the fairness and adequacy of representation by the named plaintiff, Hamm and
14 the proposed class share the same claims and interest in obtaining relief and Hamm is vigorously
15 pursuing relief on behalf of the proposed class. Hamm shares an interest with members of the
16 proposed class in proving that the 722.9 transmissions were defective and that the proposed class
17 was injured as a result of the alleged defect. MBUSA also does not argue that Hamm has any
18 conflicts of interest with other class members. Thus, the Court finds that Hamm is an adequate
19 class representative under Rule 23(a)(4).
20 5. Ascertainability
21 Along with the explicit four requirements enumerated in Rule 23(a), many courts have
22 additionally held that Rule 23(a) contains an “implied prerequisite” that the class be
23 ascertainable. Xavier v. Philip Morris USA Inc., 787 F. Supp. 2d 1075, 1089 (N.D. Cal. 2011); see
24 also, e.g., In re Yahoo Mail Litig., 308 F.R.D. at 596; Herrera, 274 F.R.D. at 672. A class
25 definition is sufficient if the description of the class is “definite enough so that it is

1 administratively feasible for the court to ascertain whether an individual is a member.” O’Connor
2 v. Boeing N. Am. Inc., 184 F.R.D. 311, 319 (C.D. Cal. 1998) (internal citation omitted). In
3 addition, impermissibly overbroad classes can defeat a court’s ability to ascertain a class. See Red
4 v. Kraft Foods, Inc., 2012 WL 8019257, at *3 (C.D. Cal. Apr. 12, 2012).
5 Here, MBUSA argues that the proposed class is impermissibly overbroad as it may include
6 many people who never suffered any injury. Resp. at 21–22. MBUSA first points to a 0.13%
7 warranty rate for claims relating to the 722.9 transmission to support their argument that the vast
8 majority of the class never experienced any issue with their 722.9 transmission. Resp. at 22.
9 However, the Ninth Circuit has “held that proof of the manifestation of a defect is not a
10 prerequisite to class certification.” Wolin v. Jaguar Land Rover N. Am., LLC, 617 F.3d 1168, 1173
11 (9th Cir. 2010) (citing Blackie v. Barrack, 524 F.2d 891, 901 (9th Cir. 1975)).
12 Next, MBUSA asserts that all putative class members who purchased class vehicles
13 outfitted with the VGS3 or VGS4 iterations of the 722.9 transmission should be excluded as not
14 having suffered any injury. Resp. at 22. In support of this assertion, MBUSA claims Plaintiff’s
15 expert Murat Okcuoglu does not consider these iterations of the 722.9 transmission defective. Id.
16 MBUSA mischaracterizes Plaintiff’s expert Okcuoglu’s testimony. Importantly, Plaintiff’s
17 expert Okcuoglu’s testimony makes clear that he does not definitively state what specific
18 iterations he concludes are not defective or are defective. Ex. 1 to Knapp Decl. at 134:10–14, Dkt.
19 No. 100-2. As MBUSA itself quotes in their opposition, in response to MBUSA’s inquiry as to
20 which iteration of the 722.9 transmissions are defective, Plaintiff’s expert Okcuoglu clearly states
21 his position: “[b]efore I do my analysis, I cannot say with certainty. Maybe none of them are
22 defective, as you say, or maybe some of them are defective or maybe all of them are defective. But
23 as I sit here, without doing my analysis, I don’t have the answer for you.” Id. Ex. 1 at 134:10–14.
24 As Okcuoglu’s testimony demonstrates, Okcuoglu has not provided a definitive conclusion as to
25 which iterations of the 722.9 transmissions he believes are defective.

1 Further, MBUSA argues that those putative class members who have had parts of their
2 transmission “replaced for free under warranty or goodwill” do not have an injury and their
3 inclusion would render the class impermissibly overbroad. Resp. at 22. The Court agrees. If a
4 putative class includes “persons who already have received refunds or replacement parts or who
5 have not suffered any damages at all, it is not ascertainable.” Stearns v. Select Comfort Retail
6 Corp., 763 F. Supp. 2d 1128, 1152 (N.D. Cal. 2010); see also Algarin v. Maybelline, LLC, 300
7 F.R.D. 444, 455 (S.D. Cal. 2014) (“[B]ecause the class does not exclude purchasers who have
8 already received refunds through Maybelline's Refund program, it is overbroad and not
9 ascertainable.”); Conde v. Sensa, 2018 WL 4297056, at *17 (S.D. Cal. Sept. 10, 2018) (“the Court
10 finds that Plaintiff [] has failed to establish an ascertainable class because the proposed class does
11 not exclude purchasers who have already received funds from the FTC settlement”); Minkler v.
12 Kramer Labs., Inc., 2013 WL 3185552, at *3 (C.D. Cal. Mar. 1, 2013) (“The Class will also
13 include hundreds of members who have already received refunds from Defendants pursuant to
14 Defendants' money back guarantee. However, such members have no injury and no standing to
15 sue.”) (internal quotations and alterations omitted); Turcios v. Carma Labs., Inc., 296 F.R.D. 638,
16 645 (C.D. Cal. 2014) (“At a minimum, the proposed class is overbroad because it would include
17 consumers who already received refunds and, therefore, have not suffered any damages.”).
18 In Stearns, a plaintiff sought to represent a class of bed purchasers in a suit against a
19 defendant bed manufacturer to recover damages due to an alleged defect causing mold growth in
20 beds purchased by the putative class. Stearns, 763 F. Supp. 2d at 1134–35. In holding that the
21 putative class was not ascertainable, the Stearns court reasoned that those class members who may
22 “already have received refunds or replacement parts” from the defendant would have “no injury
23 and no standing to sue” as those class members would have no out-of-pocket damages resulting
24 from the alleged defect. Stearns, 763 F. Supp. 2d at 1152.

27 ORDER DENYING MOTION FOR CLASS CERTIFICATION; DENYING MBUSA’S
MOTION TO STRIKE EXPERT REPORT OF D.C. SHARP AND MOTION TO STRIKE
1 Here, anyone who had purchased Mercedes-Benz vehicles with the allegedly defective
2 722.9 transmission would be included in the putative class with no differentiation within the class
3 as to those who may have had received repairs and/or replacement parts, at no cost, to their
4 transmission by MBUSA or its agents. Like in Stearns, those class members who may have
5 received repairs and/or replacement parts to their transmission at no cost would also have “no
6 injury and no standing to sue.” Stearns, 763 F. Supp. 2d at 1152. In effect, these class members
7 have already been made whole from any loss stemming from the alleged defect and thus are
8 improperly included within the class.
9 The overbreadth of the putative class, however, is easily cured by excluding owners and
10 lessees of Mercedes-Benz vehicles equipped with the 722.9 transmission who have received any
11 free repairs to or free replacement of their 722.9 transmission by MBUSA or its agents. See Mazur
12 v. eBay Inc., 257 F.R.D. 563, 568 (N.D. Cal. 2009) (recognizing the court’s inherent power to
13 modify proposed class definitions to make them sufficiently definite) (citing Hagen v. City of
14 Winnemucca, 108 F.R.D. 61, 64 (D. Nev. 1985)). The Court finds that the following definitions
15 would make the proposed class and the alternative proposed class more ascertainable:
16 All California owners and lessees of Mercedes-Benz vehicles
equipped with the 722.9 7G Tronic transmission who have not
17 received any free repairs to or free replacement of their 722.9
transmission by Defendant Mercedes-Benz USA, LLC (“MBUSA”)
18 or its agents. Excluded from this Class definition are all employees,
officers, or agents of MBUSA. Also excluded from this Class
19 definition are all judicial officers assigned to this case as well as their
staff and immediate families.
20
21 In the alternative, the narrower class is defined as:
22 All California owners and lessees of Mercedes-Benz vehicles
equipped with the VGS1 generation of the 722.9 7G Tronic
23 transmission (which were equipped on the 2004-2007 Mercedes
model year vehicles outfitted with the 722.9 7G Tronic transmission)
24 who have not received any free repairs to or free replacement of their
722.9 transmission by MBUSA or its agents. Excluded from this
25 Class definition are all employees, officers, or agents of MBUSA.
Also excluded from this Class definition are all judicial officers

2 Additionally, as previously provided in Hamm’s original class definitions, excluded from both
3 definitions are all persons who claim personal injuries resulting from the defect alleged in this
4 action. Both definitions also are limited to natural persons. The Court proceeds with the Rule 23
5 analysis under the Court-modified class definition.
6 ii. Rule 23(b)(3)
7 Predominance
8 Rule 23(b)(3) requires that “questions of law or fact common to class members
9 predominate over any questions affecting only individual members.” Fed. R. Civ. P. 23(b)(3). This
10 requirement “tests whether proposed classes are sufficiently cohesive to warrant adjudication by
11 representation.” Amchem Prods., Inc. v. Windsor, 521 U.S. 591, 623, 117 S.Ct. 2231, 138 L.Ed.2d
12 689 (1997). Class certification under Rule 23(b)(3) is proper when common questions represent a
13 significant portion of the suit and can be resolved for all members of the class in a single
14 adjudication. Comcast v. Behrend, 569 U.S. 27, 133 S.Ct. 1426, 185 L.Ed.2d 515 (2013). Rule
15 23(b)(3) demands a showing that questions common to the class predominate, not that those
16 questions “will be answered, on the merits, in favor of the class.” Alcantar v. Hobart Serv., 800
17 F.3d 1047, 1053 (9th Cir. 2015). Importantly, the premise of a Rule 23(b)(3) certification ruling is
18 not to adjudicate the case; rather, it is to select the method best suited to adjudication of the
19 controversy “fairly and efficiently.” Amgen Inc. v. Connecticut Retirement Plans and Trust Funds,
20 568 U.S. 455, 461, 133 S.Ct. 1184, 185 L.Ed.2d 308 (2013).
21 Here, Hamm presents several common issues that he argues predominate in the proposed
22 class in accordance with Rule 23(b)(3). See Fed. R. Civ. P. 23(b)(3). First, Hamm argues that
23 proving the existence of the systemic defect present in 722.9 transmissions presents a
24 predominating question. Motion at 9. Second, Hamm argues that MBUSA’s duty to disclose the
25 alleged defect present in the 722.9 transmission is a common predominating question. Id. at 13.

CASE NO.: 5:16-CV-03370-EJD
27 ORDER DENYING MOTION FOR CLASS CERTIFICATION; DENYING MBUSA’S
MOTION TO STRIKE EXPERT REPORT OF D.C. SHARP AND MOTION TO STRIKE
1 Third, Hamm argues that MBUSA’s knowledge of the allege defect poses a common
2 predominating question. Id. at 15. Fourth, Hamm argues that class members’ reliance on
3 MBUSA’s alleged non-disclosure of the defect is a common predominating question. Id. Fifth,
4 Hamm argues that proving that class members suffered an injury as a result of MBUSA’s non-
5 disclosure of the alleged defect is a common predominating question. Id. at 19.
6 In contrast, MBUSA asserts that individual issues will predominate for a number of
7 reasons. First, MBUSA argues that Hamm has failed to produce sufficient evidence and a theory
8 capable of demonstrating a common classwide defect. Resp. at 6, 12. Second, MBUSA argues that
9 Hamm cannot prove MBUSA’s knowledge of the allege defect using common evidence. Id. at 16.
10 Third, MBUSA argues that Hamm will not be able to show that exposure to and reliance on
11 omissions of the alleged defect would be common to the class. Id. at 17. Fourth, MBUSA argues
12 that Hamm has not presented a damages model that aligns with his legal theory. Id. at 22–23. The
13 Court considers these arguments in succession and, as discussed further below, concludes that
14 Hamm overcomes MBUSA’s arguments against predominance under Rule 23(b)(3) with the
15 exception of determining reliance. Ultimately, the Court finds that, because individual inquiries
16 will predominate in determining reliance across the class, the predominance requirement under
17 Rule 23(b)(3) is not met and the class cannot be certified as a result.
18 1. Common Defect
19 MBUSA asserts that Hamm fails to produce any evidence or theory that identifies a
20 common defect in the 722.9 transmissions. Resp. at 6. More specifically, MBUSA argues that
21 Hamm must show at the class certification stage what precisely is defective about the 722.9
22 transmissions. Id. MBUSA points to the many iterations and components of the 722.9
23 transmissions to support its contention that Hamm’s allegations of a common defect are
24 insufficient. Id. at 7.

1 Hamm argues the opposite. He contends that the inquiry at the class certification stage is
2 not whether a common defect exists or has been proven but, instead, whether the plaintiff has
3 established a means by which he intends to make that proof from evidence common to the class.
4 Motion at 10–11.
5 Hamm’s position is well supported by a number of defective product cases. See Victorino,
6 2019 WL 5268670, at *6; In re Arris Cable Modem Consumer Litig., 327 F.R.D. 334, 361 (N.D.
7 Cal. 2018) (“Plaintiffs’ burden at [the class certification] stage is not to establish that the alleged
8 common latency defects exist. Instead, Plaintiffs’ burden is to establish that the existence of the
9 defects is subject to common proof, and that such common questions predominate over individual
10 questions.”); Edwards v. Ford Motor Co., 603 F. App’x 538, 540 (9th Cir. 2015) (“In order to
11 satisfy the predominance requirement, the plaintiff need not prove the existence of the defect.”);
12 Amgen Inc. v. Connecticut Ret. Plans & Tr. Funds, 568 U.S. 455, 459, 133 S. Ct. 1184, 1191, 185
13 L. Ed. 2d 308 (2013) (“Rule 23(b)(3) requires a showing that questions common to the class
14 predominate, not that those questions will be answered, on the merits, in favor of the class.”).
15 Here, Hamm has identified the type of common evidence that he will use to prove his
16 theory and thus may provide answers to common questions predominating throughout the class.
17 Specifically, Hamm’s expert opines that “[b]y comparing the differences between the ‘repair kit’
18 parts and the original [non-defective] parts that the ‘repair kit’ contains, it is possible to ascertain
19 directly the changes that were made by the ‘repair kit’ to address the problem at hand. This
20 comparison, in turn, provides a direct means of assessing the presence and nature of the common
21 defect that plaintiff alleges plagues the 722.9 7G Tronic transmission.” Ex. 1 to Katriel Decl.,
22 Okcuoglu Expert Rpt. ¶34. As such, Hamm has sufficiently outlined a common evidentiary basis
23 by which the alleged defect may be proven across the class in a manner that predominates over
24 individualized inquiries.3

27 ORDER DENYING MOTION FOR CLASS CERTIFICATION; DENYING MBUSA’S
MOTION TO STRIKE EXPERT REPORT OF D.C. SHARP AND MOTION TO STRIKE
1 2. MBUSA’s Knowledge of the Alleged Defect
2 Hamm contends that MBUSA’s knowledge of the alleged defect prior to selling vehicles
3 outfitted with the 722.9 transmission presents another common predominating question providing
4 an answer uniform across the class. Motion at 15. To evidence MBUSA’s knowledge of the
5 alleged defect, Hamm points to potential “information presented to MBUSA about the defect by
6 customers, dealers, or its supplier,” as well as MBUSA’s documentation of warranty claims, as
7 early as 2003, relating to problems with the 722.9 transmissions. Id.
8 MBUSA counters that documentation of warranty claims is “insufficient to show that [a
9 defendant] had knowledge” of an alleged defect across all class products. Resp. at 16. (quoting
10 Berenblat v. Apple, Inc., 2010 WL 1460297, at *9 (N.D. Cal. Apr. 9, 2010)). However, MBUSA’s
11 reliance on Berenblat is misplaced. See Berenblat, 2010 WL 1460297, at *9. To begin, Berenblat
12 contained no discussion of product warranty claims whatsoever. Id. In Berenblat, a defendant
13 moved to dismiss a putative class of plaintiffs’ fraud-based claims for failure to allege, among
14 other things, the defendant’s knowledge of an alleged product defect. See id. at *1. The Berenblat
15 court concluded that complaints posted on the defendant’s consumer website, without more, were
16 insufficient to show the defendant had knowledge of the alleged defect. See id. at *9. Contrasting
17 Berenblat, consumers posting on a website cannot be deemed to be equivalent to the intake of
18 warranty claims for the purposes of showing a defendant’s knowledge of an alleged defect. Id.
19 While MBUSA’s attacks on the use of warranty claims to evidence MBUSA’s knowledge of the
20 alleged defect may be better directed at a fact-finder, such assertions do not defeat predominance
21 for Hamm under Rule 23(b)(3).
22 3. Damages Model
23 The calculations of damages attributable to each class member “is invariably an individual
24 question and does not defeat class action treatment.” See Leyva v. Medline Indus., Inc., 716 F.3d

26 this Order.

MOTION TO STRIKE EXPERT REPORT OF D.C. SHARP AND MOTION TO STRIKE
1 510, 514 (9th Cir. 2013). Nonetheless, Plaintiff holds the burden to offer a damages model that
2 demonstrates that “damages are susceptible of measurement across the entire class for purposes
3 of Rule 23(b)(3).” Comcast, 569 U.S. at 34. This damages model “must measure only those
4 damages attributable to” Plaintiff’s theory of liability. Id. In the absence of a plausible damages
5 model that matches Plaintiff’s theory of liability, the court will have to look into individual
6 situations to determine the appropriate measure of damages.” In re MyFord Touch Consumer
7 Litig., 2016 WL 7734558, at *15 (N.D. Cal. Sept. 14, 2016). As such, class certification is
8 appropriate when a Plaintiff offers a classwide method for proving damages. See Pulaski &
9 Middleman, LLC v. Google, Inc., 802 F.3d 979, 987 (9th Cir. 2015) (citing Comcast, 569 U.S. at
10 34).
11 MBUSA argues that Hamm’s damages model fails to establish a predominating question
12 that asserts “classwide injury because it fails to isolate injuries attributable solely to the claimed
13 defect.” Resp. at 22 (citing Comcast, 569 U.S. at 35; In re Conagra Foods, Inc., 302 F.R.D. 537,
14 579 (C.D. Cal. 2014)). MBUSA offers three reasons why Hamm’s damages model is insufficient.
15 First, MBUSA claims that Hamm’s expert, Dr. Sharp, “merely compares used car prices
16 for Mercedes-Benz vehicles equipped with different (5-speed) transmissions to used car prices for
17 Mercedes-Benz vehicles with 7-speed transmissions (722.9s)” to establish an average diminution
18 in value that “is not tied to any specific aspect of the many different 722.9s.” Resp. at 23. MBUSA
19 is oversimplifying Dr. Sharp’s econometric hedonic regression model. Dr. Sharp’s regression
20 model incorporates and controls for a spectrum of different car characteristics. Id. As such, Dr.
21 Sharp’s regression model seeks to isolate the effect of the 722.9 transmission on a vehicle’s value
22 relative to the value of a vehicle without an allegedly defective transmission. Id. Similar regression
23 analyses have been frequently accepted by courts within the Ninth Circuit. See Schmitt v.
24 Younique LLC, 2019 WL 1431906, at *9 -*10 (C.D. Cal. Jan. 10, 2019); In re ConAgra Foods,
25 Inc., 90 F. Supp. 3d 919, 946-48 (C.D. Cal. 2015); In re Toyota Motor Corp. Hybrid Brake

1 Marketing, Sales, Practices and Prods. Liab. Litig., 2012 WL 4904412, at *4 (C.D. Cal. Sept. 20,
2 2012); McCrary v. Elations Company LLC, 2014 WL 12589137, at *7 - *10 (C.D. Cal. Dec. 2,
3 2014). This Court is satisfied that Hamm’s regression model, seeking to valuate the presence of
4 the allegedly defective 722.9 transmission in class vehicles, is sufficiently tied to his theory of
5 liability.
6 After isolating the effect of the 722.9 transmission on a class vehicles’ dollar value via a
7 regression analysis, Plaintiff’s expert Dr. Sharp employs a sum-of-years’ (“SYD”) digits
8 accounting method “in order to allocate the loss of value among the original and used subsequent
9 owners over the years.” Motion at 23. Through the SYD method, Hamm seeks to allocate a
10 portion of the 722.9 transmission’s value, as determined by Hamm’s regression analysis, to the
11 current vehicle’s owner. Id. Because class vehicles may have had multiple owners, Hamm’s SYD
12 method depreciates the value of the 722.9 transmissions to account for previous ownership. Id.
13 MBUSA attacks Hamm’s use of a sum-of-years’ digits accounting method for failing to account
14 for class members who purchased their class vehicles after the alleged defect was publicly
15 disclosed and therefore purchased their class vehicle already factoring in the information regarding
16 the alleged defect. Resp. at 24. Because of this, MBUSA claims that the SYD method fails to
17 “overcome individualized inquiries” and therefore cannot satisfy predominance. Id. Throughout its
18 opposition, MBUSA denies the notion that there was ever any public disclosure regarding the
19 presence of a defective 722.9 transmission. However, here, in MBUSA’s argument against
20 Hamm’s utilization of its SYD method, MBUSA is faulting Hamm for failing to incorporate class
21 members who purchased their class vehicles after the alleged defect was disclosed, an event
22 MBUSA maintains never occurred. Resp. at 24 (emphasis added). In light of these duplicitous
23 assertions, MBUSA’s argument against Hamm’s SYD methodology lacks merit and does not
24 defeat predominance.

27 ORDER DENYING MOTION FOR CLASS CERTIFICATION; DENYING MBUSA’S
MOTION TO STRIKE EXPERT REPORT OF D.C. SHARP AND MOTION TO STRIKE
1 Finally, MBUSA argues that Hamm’s proposal for restitution under the UCL – that class
2 members are entitled to recover the cost of replacement or repair parts to their allegedly defective
3 722.9 transmission – also fails to satisfy predominance because it operates under the “assumption
4 that no class member received any benefit from the replacement or repairs.” Resp. at 24 (quoting
5 Philips, 2016 U.S. Dist. LEXIS 177672, at *74-*75). However, Hamm’s proposal for restitution
6 under the UCL here can be distinguished from Philips. In Philips, the court denied a plaintiff’s
7 damages model that sought “reimbursement of the full amount paid for replacement or repair” of
8 allegedly defective power steering systems. Philips, 2016 WL 7428810, at *22 (emphasis added).
9 The Philips court reasoned that “[r]ecovering the full amount of replacement and repair costs
10 would be justified only ‘if not a single class member received any benefit’ from those
11 replacements or repairs.” Id. (quoting Caldera v. J.M. Smucker Co., 2014 WL 1477400, at *4
12 (C.D. Cal. Apr. 15, 2014)). While Hamm is silent as to any benefit (or lack thereof) that class
13 members may have received as a result of repairs to the 722.9 transmissions, Hamm’s theory of
14 restitution can be characterized as one seeking to disgorge MBUSA from profits attained from
15 class members solving a problem that MBUSA allegedly created. See Feitelberg v. Credit Suisse
16 First Bos., LLC, 134 Cal. App. 4th 997, 1013, 36 Cal. Rptr. 3d 592, 602–03 (2005) (“As the
17 California Supreme Court held, ‘disgorgement of money obtained through an unfair business
18 practice is an available remedy in a representative action only to the extent that it constitutes
19 restitution.’” (quoting Korea Supply, supra, 29 Cal.4th at 1145, 131 Cal. Rptr. 2d 29, 63 P.3d
20 937)). Specifically, Hamm alleges that “by selling the Class Vehicles with a defective
21 transmission, MBUSA was able to realize a profit at the expense of class members who had to pay
22 for a replacement transmission conductor plate or valve body.” Motion at 24. Notably, Hamm is
23 not proposing “reimbursement of the full amount paid for replacement or repair” of the 722.9
24 transmissions, costs that may include labor and other services in addition to the cost of
25 replacement parts. Philips, 2016 WL 7428810, at *22. In contrast, Hamm’s proposal for restitution
26
CASE NO.: 5:16-CV-03370-EJD
27 ORDER DENYING MOTION FOR CLASS CERTIFICATION; DENYING MBUSA’S
MOTION TO STRIKE EXPERT REPORT OF D.C. SHARP AND MOTION TO STRIKE
1 suggests that each “class member would be entitled to recover back the cost of these replacement
2 parts,” thus distinguishing Hamm’s proposal from the type of blanket full reimbursement sought
3 in Philips. Motion at 24 (emphasis added); c.f. Philips, 2016 WL 7428810, at *22. As such,
4 MBUSA’s argument against Hamm’s proposal for restitution under the UCL does not negate
5 predominance for Hamm under Rule 23(b)(3).
6 4. Reliance
7 Next, MBUSA argues that individual questions will predominate throughout the class
8 when demonstrating exposure to and reliance on omissions of the alleged 722.9 transmission
9 defect. Because MBUSA contends that it has disclosed symptoms of the alleged defect in the
10 owners’ manuals for the various class vehicles4, MBUSA argues that extensive individual
11 inquiries will be necessary to decide whether class members were exposed to and relied on the
12 information contained in its owners’ manuals. Resp. at 17. As such, a class member who read the
13 owner’s manual may have no damages whatsoever “as he would not have had ‘an expectation that
14 the [transmission] would work without flaws.’” Id. (quoting Philips, 2016 U.S. Dist. LEXIS
15 177672, at *52).
16 To prevail under a CLRA claim, a plaintiff must show that had a disclosure been made, the
17 plaintiff would reasonably have been aware of the disclosure and, if so, would have behaved
18 differently. See Daniel v. Ford Motor Co., 806 F.3d 1217, 1225-26 (9th Cir. 2015). Hamm argues
19 that reliance on MBUSA’s omission of the alleged defect may be satisfied through common
20 evidence that class members would have been aware of a disclosure regarding the defect and the
21 notion that class members would have behaved differently, based on their knowledge of such a
22
23 4 MBUSA maintains that the possibility of “limp mode” was included in the owners’ manuals for
Mercedes-Benz class vehicles and that the owners’ manuals are readily available to consumers,
24 including prior to purchase. “For example, the owner’s manual for the 2006 CLK 350 Mercedes-
Benz vehicle owned by Plaintiff Hamm provides: Emergency operation (Limp Home Mode) If
25 vehicle acceleration worsens or the transmission no longer shifts, the transmission is most likely
operating in limp home (emergency operation) mode. In this mode only second gear and reverse
26 gear can be activated.” Keller Decl. ¶ 21, Dkt. No. 100-10.

27 ORDER DENYING MOTION FOR CLASS CERTIFICATION; DENYING MBUSA’S
MOTION TO STRIKE EXPERT REPORT OF D.C. SHARP AND MOTION TO STRIKE
1 disclosure, may be presumed across the class. Motion at 15. Showing that a class member would
2 have behaved differently may indeed be presumed if the omission is material. See Daniel, 806
3 F.3d at 1225. Importantly, materiality can be determined on an objective standard because under
4 the California Supreme Court's decision in Tobacco II, “[a]n omission is material if a reasonable
5 consumer ‘would attach importance to its existence or nonexistence in determining his choice of
6 action in the transaction in question.’” Daniel, 806 F.3d at 1225 (quoting In re Tobacco II Cases,
7 46 Cal. 4th 298 (2009)). Thus, materiality can be determined on a classwide basis using a
8 “reasonable consumer” standard. Id.
9 Even with a showing that an omission is material and thus class members would have
10 reasonably behaved differently had they been armed with information regarding the alleged defect,
11 Hamm must still demonstrate that class members would have been aware of any such disclosure of
12 the alleged defect. Hamm cites to Doyle v. Chrysler Group LLC in support of the proposition that
13 when a manufacturer is “engaged in a ‘wholesale nondisclosure’ of the alleged defect, evidence
14 that the consumer class members would have been aware of a disclosure of a material defect may
15 be presumed.” Motion at 17; Doyle v. Chrysler Grp. LLC, 2014 WL 3361770, at *6 (C.D. Cal.
16 July 3, 2014). While courts may indeed often infer reliance, “the Ninth Circuit has also held that
17 the presumption of reliance is not always appropriate,” particularly in circumstances where it
18 cannot be conclusively said that a defendant manufacturer is engaged in a wholesale nondisclosure
19 of an alleged defect. Philips, 2016 WL 7428810, at *15 (N.D. Cal. Dec. 22, 2016); see also Mazza
20 v. Am. Honda Motor Co., 666 F.3d 581, 596 (9th Cir. 2012); Butler v. Porsche Cars N. Am., Inc.,
21 2017 WL 1398316, at *10 (N.D. Cal. Apr. 19, 2017); In re Myford Touch Consumer Litig., 2016
22 WL 7734558, at *21 (N.D. Cal. Sept. 14, 2016).
23 In Mazza v. American Honda Motor Company, the Ninth Circuit rejected arguments by
24 plaintiffs that the court should presume that class members relied on alleged omissions and
25 misleading statements by the defendant automobile manufacturer in regard to an allegedly

MOTION TO STRIKE EXPERT REPORT OF D.C. SHARP AND MOTION TO STRIKE
1 defective braking system. See Mazza, 666 F.3d at 596. The Ninth Circuit held that a presumption
2 of reliance in Mazza was inappropriate largely because the defendant auto manufacturer’s
3 statements in their advertising materials “d[id] not deny that limitations exist” as to the braking
4 system. Id. The Mazza court reasoned that those class members who were exposed to the
5 defendants’ statements would likely not have had the expectation that the braking system would
6 not suffer from any flaws and thus a presumption of reliance is improper. Id.
7 Relying on the Ninth Circuit’s holding in Mazza, the court in Philips similarly denied a
8 proposed named plaintiff’s argument that reliance may be presumed across a purported class of
9 purchasers of automobiles with an allegedly defective power steering system. Philips, 2016 WL
10 7428810, at *16. In Philips, the court highlighted that “a warning about sudden [power steering]
11 failure was present in the owner's manuals for all class vehicles” and thus, “it would require
12 extensive individualized inquiries to know which class members had the opportunity to read these
13 portions of the owner's manuals before purchasing their vehicles.” Id. at *16. The Philips court
14 further noted that, “[a] class member who read the owner's manual may therefore have no
15 damages.” Id. In light of these owners’ manual warnings of the symptoms of the alleged defect,
16 the Philips court held that “class members were exposed to ‘quite disparate information,’ some of
17 which explicitly acknowledged the limitations of the [power steering] systems, and thus a
18 presumption of reliance is inappropriate.” Id. at *16 (quoting Stearns v. Ticketmaster Corp., 655
19 F.3d 1013, 1020 (9th Cir. 2011)). Because “individual issues will predominate over common
20 issues in determining reliance,” the Philips court denied the plaintiffs’ motion for class
21 certification.
22 Here, MBUSA’s disclosures in its owner’s manual are comparable to the very symptoms
23 of the defect that Hamm alleges, that is that “the car locked into low gear [and] was left unable to
24 accelerate.” Motion at 2. In comparison, the owner’s manual for Hamm’s 2006 CLK 350
25 Mercedes-Benz similarly describes that “[i]f vehicle acceleration worsens or the transmission no

1 longer shifts, the transmission is most likely operating in limp home (emergency operation) mode.
2 In this mode only second gear and reverse gear can be activated.” Keller Decl. ¶ 21, Dkt. No. 100-
3 10. Similar to the class members in Philips and Mazza, class members “who read the warnings in
4 Class Vehicles’ owner’s manuals would be aware that ‘limitations exist’ and that the
5 [transmission] may fail unexpectedly.” Philips, 2016 WL 7428810, at *16 (quoting Mazza, 666
6 F.3d at 596). As such, the unknown number of class members who may have been exposed to the
7 information contained in the owners’ manuals discussing the possibility of “limp mode” would
8 likely have no damages. To decipher which class members were aware of the potential “limp
9 mode” failure of their transmission would require extensive individual inquiries and thus a
10 presumption of reliance is inappropriate. Philips, 2016 WL 7428810, at *23. Therefore, because
11 the Court finds that “the issue of ... reliance is a matter that would vary from consumer to
12 consumer,” individual issues will predominate over common issues in determining reliance.
13 Philips, 2016 WL 7428810, at *16 (quoting Webb v. Carter's Inc., 272 F.R.D. 489, 502 (C.D. Cal.
14 2011). This defeats predominance for Hamm under Rule 23(b)(3) and warrants the denial of class
15 certification.
16 B. Daubert Motions
17 MBUSA moves to strike Dr. D.C. Sharp and Murat Okcuoglu’s expert reports in support
18 of Plaintiff’s Motion for Class Certification for failing to meet the standards required by Daubert
19 v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993) and Rule 702 of the Federal Rules of
20 Evidence. The Court DENIES MBUSA’s motion to exclude the expert report of Dr. Sharp and
21 DENIES MBUSA’s motion to exclude the expert report of Murat Okcuoglu.
22 Federal Rule of Evidence 702 allows admission of “scientific, technical, or other
23 specialized knowledge” by a qualified expert if it will “help the trier of fact to understand the
24 evidence or to determine a fact in issue.” Fed. R. Evid. 702. Expert testimony is admissible
25 pursuant to Rule 702 if it is both relevant and reliable. Daubert, 509 U.S. at 589, 113 S.Ct. 2786.

4 duty falls squarely upon the district court to ‘act as a gatekeeper to exclude junk science that does
5 not meet Federal Rule of Evidence 702’s reliability standards.’” Estate of Barabin v.
6 AstenJohnson, Inc., 740 F.3d 457, 463 (9th Cir. 2014) (en banc) (quoting Ellis v. Costco
7 Wholesale Corp., 657 F.3d 970, 982 (9th Cir. 2011)). However, this duty is to evaluate not the
8 correctness of the expert’s conclusions, but the principles and methodology used to generate the
9 conclusions. Primiano v. Cook, 598 F.3d 558, 564 (9th Cir. 2010). Moreover, the inquiry into
10 admissibility of expert opinion is a “flexible one,” where “[s]haky but admissible evidence is to be
11 attacked by cross examination, contrary evidence, and attention to the burden of proof, not
12 exclusion.” Id. (citing Daubert, 509 U.S. at 594, 113 S.Ct. 2786). In other words, the Court has
13 broad discretion and flexibility in structuring and assessing an expert’s reliability. Murray v. S.
14 Route Mar. SA, 870 F.3d 915, 924 (9th Cir. 2017). The Ninth Circuit has approved of the
15 application of the standard in Daubert to expert reports in support of or in opposition to motions
16 for class certification. See Ellis v. Costco Wholesale Corp., 657 F.3d 970, 982 (9th Cir. 2011)
17 1. Motion to Strike Expert Report of Murat Okcuoglu
18 MBUSA does not dispute that Okcuoglu is qualified to offer an expert opinion. Instead,
19 MBUSA argues that Okcuoglu’s report should be excluded because Okcuoglu has not identified
20 an alleged defect, has not developed any methodology for identifying the alleged defect that may
21 be applied to the facts of the case, and because Okcuoglu’s opinions do not “fit” Hamm’s class
22 certification theory. Def.’s Mot. to Strike the Report of Pl.’s Expert Murat Okcuoglu at 1–2, Dkt.
23 No. 101 (“Okcuoglu Mot. to Strike”).
24 First, MBUSA asserts that Okcuoglu’s failure to offer a methodology for determining the
25 existence of an alleged common defect requires that his expert report be stricken. Okcuoglu Mot.

27 ORDER DENYING MOTION FOR CLASS CERTIFICATION; DENYING MBUSA’S
MOTION TO STRIKE EXPERT REPORT OF D.C. SHARP AND MOTION TO STRIKE
1 to Strike at 3. Specifically, MBUSA contends that Okcuoglu has “failed ‘to provide any specific
2 information about the [proposed] methodology’ and only offered an ‘unsupported, conclusory
3 promise of reliable data.” Id. at 3 (quoting Pedroza v. PetSmart, Inc., 2013 U.S. Dist. LEXIS
4 53794, at *11-*12 (C.D. Cal. Jan. 28, 2013)) (internal quotations omitted). The Court disagrees.
5 Okcuoglu’s methodology entails disassembling MBUSA’s “repair kit” and comparing it with the
6 “unrepaired original exemplar” parts from 722.9 transmissions to determine what the “repair kit”
7 seeks to remedy within the 722.9 transmissions. Opp’n to Mot. to Strike the Report of Pl.’s Expert
8 Murat Okcuoglu at 8, Dkt. No. 106 (“Okcuoglu Opp’n”); see also Katriel Decl., Ex. 1 ¶ 34
9 (“Because Daimler AG manufactured the ‘repair kits’ for the 722.9 7G Tronic transmission, one
10 can compare the components present in the ‘repair kits’ with the components in the original 722.9
11 7G Tronic transmission before the use of the ‘repair kit.’ By comparing the differences between
12 the ‘repair kit’ parts and the original parts that the ‘repair kit’ contains, it is possible to ascertain
13 directly the changes that were made by the ‘repair kit’ to address the problem at hand.”). Okcuoglu
14 has “already procured several exemplar vehicles and valve bodies” of the various 722.9
15 transmissions “to undertake that analysis.” Id. at 3.
16 Further, after reviewing a number failures and complaints regarding the 722.9
17 transmissions, Okcuoglu has identified the conductor plate of the 722.9 transmissions as a
18 common denominator in the alleged defect across the 722.9 transmission, and thus the conductor
19 plate is a focus of his analysis. Id. at 3–4 (quoting Ex. 2 to Katriel Opp. Decl., at 126:8–12, 127:4–
20 6). The Court is satisfied that Okcuoglu has presented a sufficient methodology for determining
21 the existence of an alleged common defect plaguing the 722.9 transmissions.
22 Next, MBUSA argues that Okcuoglu’s report should be stricken because Okcuoglu has not
23 applied a reliable methodology to the facts of the case. Okcuoglu Mot. to Strike at 4–5. More
24 specifically, MBUSA argues that Okcuoglu’s incompletion of “his proposed comparison
25 methodology renders his opinions unreliable and unhelpful.” Id. at 5. However, Okcuoglu is under

27 ORDER DENYING MOTION FOR CLASS CERTIFICATION; DENYING MBUSA’S
MOTION TO STRIKE EXPERT REPORT OF D.C. SHARP AND MOTION TO STRIKE
1 no mandate to have completed his methodology at this juncture. Indeed, “[a]t the class
2 certification stage an expert is not charged with resolving factual disputes or determining the
3 merits of the case.” In re Toyota Motor Corp. Hybrid Brake Mktg., 2012 WL 4904412, at *4; see
4 also Keegan v. Am. Honda Motor Co., 284 F.R.D. 504, 515 (C.D. Cal. 2012) (holding that “[o]n a
5 motion for class certification, it is not necessary for the expert testimony to resolve factual
6 disputes going to the merits of plaintiffs’ claim or claims.”); Ellis v. Costco Wholesale Corp., 657
7 F.3d 970, 983 (9th Cir. 2011); Tait v. BSH Home Appliances Corp., 289 F.R.D. 466, 495 (C.D.
8 Cal. 2012). Thus, Okcuoglu’s expert report need not be stricken because he has yet to complete
9 the comparison analysis methodology he has outlined.
10 Finally, MBUSA contends that Okcuoglu’s comparison analysis proposal should be
11 stricken because it is not relevant and does not “fit” Hamm’s theory of class certification.
12 Okcuoglu Mot. to Strike at 7. Specifically, MBUSA points to Okcuoglu’s lack of conclusive
13 statements presently identifying the specific cause of the alleged defect present in the 722.9
14 transmissions as indicative of Okcuoglu’s inability to identify the classwide defect at the crux of
15 Hamm’s theory. Id. at 7. MBUSA cites to Grodzitsky v. Am. Honda Motor Co. in support of the
16 proposition that an expert must identify a specific defect, rather than “general ‘potential’
17 problems,” for the expert’s opinion to fit a plaintiff’s class certification argument. Id. at 8 (quoting
18 Grodzitsky v. Am. Honda Motor Co., 957 F.3d 979, 986 (9th Cir. 2020)). MBUSA’s reliance on
19 Grodzitsky is misplaced. In Grodzitsky, the expert opinion in question was stricken because the
20 expert “articulated no scientific basis for his observations. And the only testing he
21 performed was not designed to identify any defects, let alone a common defect.” Grodzitsky, 957
22 F.3d at 986. That is not the case here. The very purpose of Okcuoglu’s methodology is to identify
23 the precise cause of the defect allegedly present in the 722.9 transmissions by comparing
24 MBUSA’s “repair kits” to unrepaired 722.9 transmissions.

27 ORDER DENYING MOTION FOR CLASS CERTIFICATION; DENYING MBUSA’S
MOTION TO STRIKE EXPERT REPORT OF D.C. SHARP AND MOTION TO STRIKE
1 In any event, as Hamm points out, “a plaintiff is not required to identify the precise cause
2 of a defect.” Wallace v. SharkNinja Operating, LLC, 2020 WL 1139649, at *6 (N.D. Cal. Mar. 9,
3 2020); Asghari v. Volkswagen Group of America, Inc., 42 F. Supp. 2d 1306, 1326, n.72 (C.D. Cal.
4 2013); Hardt v. Chrysler Grp. LLC, 2015 WL 12683965, at *5 (C.D. Cal. June 15, 2015); Barrera
5 v. Jaguar Land Rover North Am., LLC, 2020 WL 4003653, at *3 (C.D. Cal. Jun. 3, 2020);
6 Cholakyan v. Mercedes-Benz USA, LLC, 796 F. Supp.2d 1220, 1237, n.60 (C.D. Cal. 2011);
7 Ehrlich v. BMW North Am., LLC, 801 F. Supp.2d 912 (C.D. Cal. 2010). Additionally, as the
8 Wallace court notes, “it is typically difficult for a plaintiff to discern the mechanical workings of a
9 product at the pleading stage.” Wallace, 2020 WL 1139649, at *6. As such, Okcuoglu’s expert
10 report need not be stricken because he has yet to identify the specific cause of the alleged common
11 defect at this stage. MBUSA’s motion is denied.
12 2. Motion to Strike Expert Report of Dr. D.C. Sharp
13 As with Plaintiff’s expert Okcuoglu, MBUSA does not dispute that Dr. Sharp is qualified
14 to offer an expert opinion. Rather, reiterating many identical arguments in their opposition to class
15 certification, MBUSA moves to exclude the expert report of Dr. Sharp for three reasons: (1)
16 MBUSA alleges Dr. Sharp has failed to apply valid scientific methodology in calculating
17 damages; (2) MBUSA alleges Dr. Sharp uses unreliable data in calculating damages and; (3)
18 MBUSA alleges Dr. Sharp’s damages model does not “fit” with Hamm’s class certification
19 theory. Def.’s Mot. to Strike the Expert Report of Pl.’s Expert D.C. Sharp at 1–2, Dkt. No. 102
20 (“Sharp Mot. to Strike”).
21 i. Sharp’s Methodology
22 Plaintiff Hamm retained Dr. Sharp to calculate damages attributable to the allegedly
23 defective 722.9 transmission on a classwide basis. Dr. Sharp performs this calculation relying on a
24 hedonic regression model, a method frequently used in economics to ascertain the relative effect
25 of variables on the price of a product. See In re Qualcomm Antitrust Litig., 328 F.R.D. 280, 304–

CASE NO.: 5:16-CV-03370-EJD
27 ORDER DENYING MOTION FOR CLASS CERTIFICATION; DENYING MBUSA’S
MOTION TO STRIKE EXPERT REPORT OF D.C. SHARP AND MOTION TO STRIKE
1 05 (N.D. Cal. 2018). In its motion to strike Dr. Sharp’s expert report, MBUSA “does not—and
2 could not—dispute that ‘regression analysis is generally a reliable method for determining
3 damages…and is a mainstream tool in economic study.’” Id. (quoting In re High-Tech, 2014 WL
4 1351040, at *14). As Hamm points out, “courts regularly recognize that hedonic regression is a
5 widely accepted econometric methodology that satisfies the four Daubert factors of testability,
6 peer review and publication, measureable error rate, and general acceptance.” Id.; see also
7 In re ConAgra Foods, Inc., 90 F. Supp. 3d 919, 947 (C.D. Cal. 2015); In re Toyota Motor Corp.
8 Hybrid Brake Mktg., Sales Practices & Prod. Liab. Litig., 2012 WL 4904412, at *4 (C.D. Cal.
9 Sept. 20, 2012). The Court is satisfied that Hamm’s expert, Dr. Sharp, has employed a valid
10 scientific methodology by utilizing a hedonic regression.
11 ii. Data and inputs used in Sharp’s Methodology
12 MBUSA asserts that Dr. Sharp’s damages model is fatally flawed because of the data
13 inputs used in creating the regression model. Sharp Mot. to Strike at 2–3. Specifically, MBUSA
14 attacks Dr. Sharp’s sample size, the number of vehicle attributes included within the model, and
15 the pricing data Dr. Sharp relied upon. Id. at 3. In any event, “district courts within and outside
16 this district have often concluded that experts' decisions about what data to use in their analysis
17 bear on the weight, not the admissibility, of expert testimony.” In re Qualcomm Antitrust Litig.,
18 328 F.R.D. 280, 305 (N.D. Cal. 2018); see also Grace v. Apple, Inc., 328 F.R.D. 320, 341 (N.D.
19 Cal. 2018); Elkies v. Johnson & Johnson Servs., Inc., 2018 WL 11223465, at *9 (C.D. Cal. Oct.
20 18, 2018); In re TFT-LCD (Flat Panel) Antitrust Litig., 2013 WL 124347, at *1 (N.D. Cal. Jan. 8,
21 2013); In re High-Tech Employee Antitrust Litig., 2014 WL 1351040, at *20 (N.D. Cal. Apr. 4,
22 2014); Brighton Collectible, LLC v. Believe Prod., Inc., 2017 WL 440255, at *6 (C.D. Cal. Jan.

24 selection of variables to include in a regression analysis is normally a question that goes to weight

2 2010); In re Air Cargo Shipping Servs. Antitrust Litig., 2014 WL 7882100, at *49 (E.D.N.Y. Oct.
3 15, 2014) (“The determination of which dataset is most reliable is a merits question and does not
4 preclude [an expert's] preference of one over the other.”). Notably, the U.S. Supreme Court has
5 held that an expert's selection of certain variables to include within a regression analysis will
6 generally “affect the analysis' probativeness, not its admissibility.” Bazemore v. Friday, 478 U.S.
7 385, 400, 106 S.Ct. 3000, 92 L.Ed.2d 315 (1986). Thus, MBUSA’s criticisms regarding the data
8 used and variables included or omitted within Dr. Sharp’s damages model should be properly
9 challenged in the adversarial process “through competing evidence and incisive cross-
10 examination.” Murray v. S. Route Mar. SA, 870 F.3d 915, 925 (9th Cir. 2017).
11 iii. The “Fit” of Sharp’s Methodology to Hamm’s Legal Theory
12 Next, MBUSA contends that Dr. Sharp’s damages model does not “fit” Hamm’s legal
13 theory by arguing that the model does not measure damages attributable to any specific component
14 or iteration of the 722.9 transmissions. Sharp Mot. to Strike at 5. However, as previously
15 addressed above, MBUSA “overlooks Hamm’s actual claim that all 722.9 transmissions,
16 regardless of which version of conductor plate or valve bodies they possessed, were defective.”
17 Opp’n to Mot. to Strike the Report of Pl.’s Expert D.C. Sharp at 18, Dkt. No. 105 (“Sharp
18 Opp’n”). Contrary to MBUSA’s claims and when considering Hamm’s legal theory, Dr. Sharp’s
19 damages model has no requirement to attribute damages to a specific component or iteration of the
20 722.9 transmissions when Hamm asserts that all of the 722.9 transmissions are defective,
21 regardless of iteration or components present.
22 MBUSA’s final argument against the “fit” of Dr. Sharp’s damages model in regard to its
23 purported failure to identify and include the date of disclosure of the alleged defect fails for lack of
24 merit under same reasoning above. MBUSA cannot assert that a disclosure of the alleged defect
25 never occurred and then simultaneously fault Hamm for failing to precisely identify when
