The Trump administration’s tariffs might hurt the car and truck industry more than help, auto industry veteran Jim Press told CNBC.

“The reality is that tariffs normally don’t go away once they’re enacted,” Jim Press said on “Closing Bell” Friday. “It’s not a negotiating tactic. And it causes a great deal of uncertainty in investment decisions, production decisions, design of product. It’s a very difficult situation for the auto companies.”

U.S. tariffs on $34 billion worth of Chinese goods went into effect at 12:01 a.m. EST on Friday. China immediately implemented retaliatory tariffs on its own. Beijing called it the "biggest trade war in economic history."

The Chinese tariffs will impact a number of American sectors, including agricultural products and autos. Now, vehicles built in the U.S. and sold overseas are subject to tariffs of up to 40 percent. Vehicles made in China and sold in the U.S., however, pay only a 25 percent tariff. In addition, China imports fewer cars to the U.S. than the other way around.

The U.S. exported 267,000 autos to China last year, and has a trade surplus of $6.4 billion in the auto sector with China.

"The reality of our cars going to China, we don't make the kinds of vehicles that the Chinese would be using on their roads with their fuel economy," said Press, who is now president of RML Automotive.

The move left many wondering how automobile manufacturers in the U.S. will cope with higher prices. Mercedes-Benz, which builds SUVs in Alabama, has not said yet how it will address the issue. BMW, however, said the tariffs would affect retail prices of models shipped out of South Carolina to China. Tesla also said in a note to consumers in China that they should expect higher prices.

Press, who spent more than four decades in the auto industry, including tenures at Toyota, Ford Motor Company, General Motors and Chevrolet, as well as serving as co-president and vice chairman of Chrysler, said nothing good comes out of trade wars.

"The outcomes are normally bad," he said. "In this case, it's really not merited based on the current situation in the U.S. auto industry. But it is perhaps a political effort to try and put pressure on China. I don't see how that's going to help American consumers."
