My 2023 GMC truck has been sitting in the shop for almost two months. First they said it was the turbo, then the radiator, then the air‑conditioning system, and now they claim the turbo shredded metal and sent it into the engine, so the entire engine must be replaced. Before this, the truck had already lost power; they changed the turbo, and just 10,000 miles later it broke down again, leaving my family and me stranded on the highway. It took them more than two weeks to give me a clear diagnosis. I pay over $1,000 per month for this truck and yet they’ve left me with a Malibu loaner I cannot work with. I’ve spent a lot of money on rental cars and lost income.It gets worse: two months after buying it, on a trip from Florida to Virginia in 2023, the brakes failed completely; the shop never figured out why and didn’t fix it. While the truck was at the dealership, they even hit it and dented the fender. Most frustrating of all, GMC has not reached out to me—I always have to call and wait on hold to get updates, and no one has offered any solution or replacement vehicle. After years of buying GMC products, my trust is gone.This is my personal experience—I’m not exaggerating.
