(a) Except as provided in subsection (a) of Code Section 10-1-790, this article shall not create or give rise to any cause of action by manufacturers or consumers against new motor vehicle dealers. No new motor vehicle dealer shall be held liable by a manufacturer or a consumer for any collateral charges, incidental charges, costs, purchase price refunds, or vehicle replacements. Manufacturers and consumers shall not make new motor vehicle dealers party to an arbitration proceeding or any other proceeding under this article. A new motor vehicle dealer that is named as a party in any proceeding brought by a consumer or a manufacturer under this article, except as provided in subsection (a) of Code Section 10-1-790, shall be entitled to an award of reasonable attorney's fees and expenses of litigation incurred in connection with such proceeding.

(b) The provisions of this article shall not impair any obligation under any manufacturer-dealer franchise agreement; provided, however, that any provision of any manufacturer-dealer franchise agreement which attempts to shift any duty, obligation, responsibility, or liability imposed upon a manufacturer by this article to a new motor vehicle dealer, either directly or indirectly, shall be void and unenforceable, except for any liability imposed upon a manufacturer by this article which is directly caused by the gross negligence of the dealer in attempting to repair the motor vehicle after such gross negligence has been determined by the hearing officer, as provided in Article 22 of this chapter, the "Georgia Motor Vehicle Franchise Practices Act."
