WASHINGTON (Reuters) -A trade group representing nearly all major automakers warned on Tuesday that new 25% tariffs on imports from Canada and Mexico imposed by U.S. President Donald Trump will lead to drastic price hikes.

"All automakers will be impacted by these tariffs on Canada and Mexico," said John Bozzella, who heads the Alliance for Automotive Innovation that represents all major automakers in the U.S. except Tesla. Members include General Motors Ford, Toyota ( TM ), Volkswagen, Hyundai and Stellantis ( STLA ).

"Most anticipate the price of some vehicle models will increase by as much as 25% and the negative impact on vehicle price and vehicle availability will be felt almost immediately."

Automakers have sounded the alarm that the tariffs will disrupt the integrated supply chain across North America that has been in place for more than 25 years. Some auto parts can cross a border six or more times before final assembly.

"You just can't relocate automotive production and the supply chain overnight. That's the challenge and the dilemma: auto tariffs in North America could end up increasing costs on consumers before jobs come back to the country," Bozzella added.

Last month, Ford CEO Jim Farley warned that 25% tariffs on Mexico and Canada would "blow a hole" in the U.S. auto industry. "What we're seeing is a lot of cost, a lot of chaos," he said last month.

The United Auto Workers praised Trump, noting his plans for further tariff actions in April.

"We are glad to see an American president take aggressive action on ending the free trade disaster that has dropped like a bomb on the working class," the union said. "We look forward to working with the White House to shape the auto tariffs in April to benefit the working class."

The American International Automobile Dealers Association noted dealers already face rising vehicle and parts prices and high interest rates. "Tariffs could directly contribute to thousands of extra dollars on sticker prices," the group said.
