Tariffs would increase car prices and potentially cause massive layoffs, experts say

President Donald Trump's proposed 25% tariffs on imports from Mexico and Canada and 10% on goods from China would likely raise the average price for a new car and could lead to massive layoffs — but by how much depends on how long the tariffs remain in place.

The tariffs are in flux, with Mexico's president on Monday winning a 30-day pause while the countries negotiate.

Assessing the tariff proposal, analysts estimate new car prices, on average, would likely increase by anywhere from $1,000 to $9,000 or more. Some vehicles would be affected more than others. They also estimate that more than 165,000 autoworkers could laid off if tariffs remain in place for any considerable time.

If Trump enacts tariffs starting Tuesday, as originally announced and as of noon Monday remained the plan for Canada and China, the timeline for when the price hikes and job impact happens could vary in the next few weeks or months depending on the vehicle and the inventory that is in stock, said Sam Abuelsamid, vice president of Market Research at Telemetry Insights.

That's because tariffs — the taxes on goods that cross international borders — do not get applied until the products actually cross the border.

"Anything that is in inventory as of today isn’t affected. Everything that crosses the border from tomorrow on gets a tariff," Abuelsamid said. "Price changes will vary based on the models, with more popular models that have lower inventories being hit the soonest."

For example, Toyota has tight inventory of the Rav4 SUV and Honda has short supply of CR-Vs and Civics, he said. All three vehicles are assembled in Canada and they probably would see an impact from tariffs in the next few weeks. The Jeep Compass, made by Stellantis, is built in Mexico. It might take a bit longer for it to be impacted because Stellantis has a good supply of inventory on the Compass, Abuesamid said.

"Prices will likely remain elevated for a similar period after tariffs are removed until that inventory is depleted," Abuelsamid said. "But parts going through the supply chain might add several weeks or months before you see adjustments."

Put simply by economist Michael Hicks, "This is the one-time biggest tax increase on America in history. So it predictability has the effect of dampening economic activity. The people affected most will be the people who are renting, people who need to buy cars, people who need to buy computers.”

Hicks, a professor at Ball State University in Muncie, Indiana, estimates the proposed tariffs will amount to a $2,000 tax on average household spending, hitting lower-income people the hardest.
