Let’s not pretend every GMC is a patriotic emblem. The GMC Terrain (the compact crossover) is assembled in San Luis Potosí, Mexico. And the Sierra HD models? Some of their heavy-duty frames come from Oshawa, Ontario, Canada. I know, right? Suddenly your truck has maple syrup in its bloodline. This isn’t a bad thing—Mexican and Canadian plants are often more modern and efficient than some U.S. facilities. But it does make the “Buy American” argument feel a little thin, like watered-down motor oil.
What About the Future? (The EV Twist)
GM is pouring billions into electric trucks, and the GMC Hummer EV is built at Factory ZERO in Detroit and Hamtramck, Michigan. Yes, that’s a real name—Factory ZERO—because it’s supposed to produce zero emissions. The irony? That plant used to build gas-guzzling Cadillacs and Chevy Volts. Talk about a career change. The upcoming GMC Sierra EV will be built alongside it, so electric GMCs are staying solidly in the Midwest. For now.
