Market surveillance program.

(a) General rule.--The department shall maintain a continuing program of market surveillance to insure that any items of vehicle equipment offered for sale in this Commonwealth

and for which approvals are required are in compliance with the law.

(b) Purchase and testing of samples.--The department may undertake at State expense random retail purchase and compliance testing of samples of equipment which is covered by a valid certificate of approval or which has been certified by its manufacturer as being in compliance with an applicable Federal motor vehicle safety standard. If the samples, upon testing, fail to meet the applicable performance requirements, the department may commence revocation proceedings pursuant to section 4105 (relating to revocation and renewal of certificates of approval).

(c) Notice of violations.--If the market surveillance program reveals instances of items of equipment being offered for sale which have not been submitted for approval as required by State law or regulation or have been disapproved or have not been certified as being in compliance with an applicable Federal standard, immediate written notice of that fact shall be furnished the dealer, distributor, wholesaler or manufacturer. The dealer shall not thereafter sell the equipment and the distributor, wholesaler or manufacturer shall recall all the equipment from all dealers.
