Trump’s Mexico And Canada Trade Threat Puts Car Prices At Risk

President Donald Trump said this week he is "not looking to renew" the US-Mexico-Canada Agreement before its July 1 review deadline, which determines whether the pact will be extended for another 16 years. As reported by Reuters, the pact governs roughly $1.6 trillion in annual trade, including roughly $400 billion in vehicle and automotive parts trade. and currently keeps USMCA-compliant goods largely exempt from broader tariffs, helping hold down prices for Americans. Automakers like Ford, GM, and Stellantis, which build extensively in Mexico and Canada, could face a tougher cost picture. Automakers are already navigating a complex tariff environment, with some imported vehicles and components facing duties if they fail to meet USMCA requirements. Dealers, meanwhile, are stuck planning around a moving target.

Why The Trade Deal Matters For Your Next Car

USMCA was built to keep North American supply chains cheap and predictable, with automotive parts accounting for over 75 percent of exports to these countries. For years, parts have crossed borders multiple times before a vehicle is finished, and the deal made sure none of that movement triggered extra taxes. Without an extension, the agreement enters rolling annual reviews but stays in force for roughly a decade unless a country exits entirely. That sounds reassuring. It isn't really. Automakers hate uncertainty almost as much as tariffs themselves, because long-term plant investments take years to plan.

There's also a physical bottleneck. The aging Ambassador Bridge between Detroit and Windsor carries over $300 million in goods daily, and a brief delay can stall Ford's F-150 production within the hour. The new Gordie Howe Bridge was supposed to fix this. Instead, Trump has threatened to delay its opening over toll disputes, adding another layer of risk to an already strained supply chain. Combine that with looming tariff changes, and the path to an affordable car gets a lot longer.

Factories In Mexico And Canada Could Take A Hit

Automakers spent decades building production networks across North America under NAFTA and later USMCA, taking advantage of largely duty-free trade. Plants building everything from pickup trucks to assembling EVs in Mexico now face a murkier future. Mexican and Canadian auto exports to the US already face a 25 percent tariff on the non-US content of a vehicle. If that expands, the math behind those investments starts to fall apart, and some companies may quietly start shifting plans back stateside.
