“These tires are not safe for off-road to highway use. After transitioning to the highway from a gravel driveway, I noticed that rocks were stuck in the treads. A significant about of rocks became dislodged and start to contact my vehicles underbody steps. I feel as if this can create significant and costly problems for the vehicles that are following close or perhaps behind in any manner. Large rocks and what I would classify as mini boulders are often found lodged in the tread and don't come out till they are picked out or fly out.”Owner report · Tires · May 2026
“Driving at approximately 30-35MPH merging in traffic, the transmission shuttered and went into reduced power mode. ECM reported a 747 code and valve body failure.”Owner report · Power Train · Nov 2025

“The transmission control mod is bad. This is a persistent problem and that's why it is on back order for up to a year. It is unethical to not issue a recall as customers have to continue to pay for the vehicle while not getting a replacement of equal capabilities. I bought a 3/4 ton truck to haul for work, not getting something that can do the same while a pay $1000+ a month is wrong. For the NHTSA not to get involved, issue some sort of recall, and allow GM to continue to take people's money while their vehicles depreciate is wrong. Is this so the government can get paid back from GM for the bailout 15 years ago?”Owner report · Power Train · Aug 2025

“This issue is pertaining to the valve body in my 10-speed transmission. While I was traveling home, the truck experienced a “wheel lockup”. The transmission shifted down aggressively, then putting the truck into limp mode. I had to travel the rest of the way home with a max speed of 35 mph. I have been without this truck for 3 months waiting on parts. This is absolutely unacceptable from gm. Extremely unsave.”Owner report · Power Train,Vehicle Speed Control · Apr 2025
