President Donald Trump's move Saturday to impose 10% additional tariffs on imports from China affects a small number of U.S. vehicles. But those tariffs are also hitting auto parts, which could increase already heightened vehicle prices for consumers.

Trump reiterated on the weekend he would impose 25% tariffs this week on goods from Mexico and Canada - including on vehicles made by General Motors and Volkswagen - but delayed a decision for a month after discussions with each country's leader.
