The Driving American Jobs Coalition, a group representing many facets of the U.S. auto industry, has formed a new coalition to oppose potential new tariffs on imported automobiles and motor vehicle parts.

Businesses affected by the auto parts industry, including collision repair shops, could scramble to cope with President Donald Trump’s tariffs on imported Chinese materials and goods, especially as those tariffs could limit where auto parts retailers can source their parts.

The U.S. federal government recently rolled out a proposal to freeze automotive fuel economy and greenhouse gas standards, and a former EPA exec disagrees with the move.

Carmakers say the standards need adjustments in light of surging light-truck sales, low gasoline prices and tepid demand for plug-in vehicles.
