Consumer Description

I bought a brand new 2025 GMC Yukon AT4 3.0 Diesel on 8/16/25 (had 213 miles on). A month later, with only 2000 miles on the vehicle, I was driving down the road and got a warning "reduced acceleration, drive with caution". Car would hardly accelerate. Had it towed to the dealer on 9/22/25. They found metal shavings in the engine oil. Said there was a quarter inch play around the camshaft (manufacture defect). Told me I need a completely new engine. It's now 12/2/25 and I still don't have a car, and mine hasn't been repaired.
