The auto industry fears that President Donald Trump’s threats to place tariffs on vehicles coming into the U.S. could drive the economy into a recession, the head of the largest auto retailer in America said today.

“Everyone in the automobile industry—doesn’t matter if you’re a retailer, a supplier or a manufacturer—is freaking out around tariffs on automobiles,” Mike Jackson, chairman and chief executive officer of AutoNation Inc., said Wednesday on Bloomberg Television. “The price point is so big, we all know it would be extremely disruptive, extremely expensive to the industry and most likely knock the economy into some sort of recession because it’s so inflationary.”

Jackson, who is also chairman of the Federal Reserve Bank of Atlanta, said he hopes trade deals can be reached with Europe, Mexico and Canada that will avoid auto tariffs that Trump said could be as high as 30 percent on vehicles imported into the U.S. The president has already imposed tariffs on foreign steel and aluminum, as well as a variety of goods from China.

“Auto tariffs would make steel and aluminum tariffs look like a company picnic,” Jackson said. “It is the big one. So it’s incomprehensible that there won’t be a solution around this whether it’s with the Europeans or within” the North American Free Trade Agreement.
