The U.S. automotive industry is facing heightened uncertainty following the Trump administration’s announcement that the United States-Mexico-Canada Agreement (USMCA) will not be extended beyond its current term. This decision initiates a potentially lengthy review process or risks the pact’s expiration by 2036 if no new agreement is reached. The auto sector, which accounted for 18% of trade among these nations last year, is particularly concerned as the USMCA governs roughly $2 trillion in goods and services annually between the three countries. Industry leaders worry that reopening negotiations could discourage investment and reduce job growth due to increased trade unpredictability.

At the heart of current discussions are the USMCA’s rules of origin, which stipulate the percentage of a vehicle’s regional content required for tariff-free status. The Trump administration is pushing to raise the regional value content for passenger vehicles from 75% to 82%, with half of that content to be produced in the U.S., a marked increase from previous agreements. Automakers highlight the challenge of meeting these stricter standards given the complex supply chains that integrate parts from many countries, including Mexico and Canada but also markets as far as China, with estimates showing up to 20,000 parts in a typical vehicle. The proposed changes could raise costs and complicate compliance, potentially prompting companies to reduce U.S. production to avoid tariffs.

Automotive trade groups representing the majority of U.S. manufacturers and suppliers have urged the U.S. Trade Representative to pursue a trilateral extension of USMCA to preserve the framework which has driven $182 billion in North American investment, predominantly benefiting the U.S. They emphasize that the current system supports an integrated supply chain critical to the industry’s competitiveness. Meanwhile, Canadian officials remain optimistic that a renegotiated deal could be reached by fall, although many expect the negotiations to be more complex than the original talks, given that broader issues beyond trade—such as immigration and crime—have entered the dialogue.

Industry consultants warn that while the administration aims to boost U.S. content in vehicles and reduce dependence on China, aggressive changes to USMCA’s rules might backfire by increasing production costs and undermining competitiveness. Instead of increasing American content, some automakers might strategically choose to minimize U.S. parts in compliance efforts or even accept tariffs on more affordable imports. Experts from AlixPartners and Boston Consulting Group recommend focusing on North American competitiveness against China rather than internal competition among the U.S., Mexico, and Canada to maintain an efficient and cost-effective supply chain. This delicate balance will be critical to the future stability and growth of the North American auto industry.
