U.S. automakers based in Detroit warn that revisions to a North American free-trade arrangement, including proposals being discussed with Mexico, could cost them billions of dollars. The warnings come as car companies continue to adjust to the financial impact of tariffs introduced by the Trump administration the previous year.

Both outlets report that executives believe additional trade changes would raise operational expenses and complicate efforts to absorb earlier disruptions. The Globe and Mail frames the issue around the ongoing strain from last year’s tariff measures. The Independent adds that companies are particularly concerned about specific proposal options being floated ahead of talks with Mexican trade officials scheduled for next month.

While the articles differ in emphasis—one focusing on the broader tariff fallout and the other on the timing and substance of the new proposal—they converge on the same concern: further revisions to regional trade terms would likely increase costs for U.S. automakers.
