Michigan Governor Rick Snyder has vetoed House Bill 4344, legislation intended to update regulations in the Michigan Motor Vehicle Service and Repair Act. The bill authors included new language that would limit the use of aftermarket parts by mandating that an aftermarket part would have to be verified by a nationally recognized automotive parts-testing agency.

In his letter to the legislature to explain the veto, the governor said that “As Michigan continues its comeback, it is imperative that we ensure all components of that industry can remain strong, including Michigan’s robust aftermarket parts industry.” He also expressed his concern about HB 4344’s effect on market competition for replacement parts on motor vehicles.

“Michigan’s aftermarket auto parts industry is strong because of its competition with the OEMs,” said Snyder. “Enacting a law to prohibit mechanics from providing high quality and safe alternatives for customers is an inappropriate impediment on the competition that has resulted in both high-quality OEM and aftermarket parts for Michigan drivers to enjoy.”
