Example complaints
Transmission and drivetrain: “Severe transmission shuttering destroyed my transmission and I need a new one according to a local body shop and a GMC service center. This is a KNOWN issue with these 10 speed transmissions, but they will not recall the ones from this year, they only recalled newer models. Car has been inspected by a local autobody shop, a 3rd party warranty company, and a GMC dealership service center. Shuddering causes severe shaking while driving between 25-65mph. No lights or other symptoms, just started occurring randomly. …”
NHTSA complaint #11737164, filed 2026-05Engine: “We just purchased our Yukon from a dealership in February (2/7/26) and it was diagnosed with premature failure of at least one AFM valve lifter as it is causing engine misfires, shaking and stalling on 7/30/26. We just hit 67,000 miles on the odometer so we are just beyond the warranty coverage. The lifters were replaced previously by the previous owners on 12/16/24.”
NHTSA complaint #11758957, filed 2026-08Brakes: “Issue with the trailer brake system keeps coming up on my dash. I know a lot of other people have had the same issue keeps dinging will not stop causes me to get distracted while driving. Unable to use other features because of this distraction and safety issue. The safety issue needs to be fixed this is an effective product with so many people having an issue you need to do a recall. I did let Graff Chevrolet in Mount Pleasant Michigan no and I took a picture and showed them.”
