WASHINGTON, March 31 (Reuters) - Two Michigan business

groups urged President Donald Trump to halt plans to impose

sweeping 25% tariffs on imported vehicles and parts, saying it

would lead to dramatic price hikes, supply chain disruptions and

pain in the auto-heavy state.

"The increased costs would cause significant disruption

throughout the supply chain and, perhaps most importantly, lead

to significant price increases to the cost to American consumers

for vehicles," said the Detroit Regional Chamber of Commerce and

MichAuto, an automotive and mobility association.

"In Michigan, where one in five jobs is automotive-related,

the pain felt by working-class citizens will be profound."
