A manufacturer must file with the department a copy of the delivery and preparation obligations required to be performed by a dealer prior to the delivery of a new vehicle to a buyer. These delivery and preparation obligations constitute the dealer’s only responsibility for product liability as between the dealer and the manufacturer. Any mechanical, body, or parts defects arising from an express or implied warranty of the manufacturer constitute the manufacturer’s product or warranty liability only, as between the manufacturer and the dealer. The provisions of this section shall not affect the obligation of dealers to perform warranty repair and maintenance as may be required by law or contract.
