“Complete Tread/belt separation originating inside the tire. I have the complete tire and the complete tread. This happened at highway speed. I'm going to the dealer to get an inspection. The only symptom was a bad vibration before the tread separation. LT275/65R20E”Owner report · Tires · Sep 2026
“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

“Bought a 2023 gmc sierra 2500 duramax. Went into limp mode took it to dealership the transmission was bad so they replace transmission after 3 month of dealer having my truck . Got the truck back still having issues with transmission not shifting right and the rear tires locking up at highway speeds .”Owner report · Power Train · Sep 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
“The contact owns a 2023 GMC Sierra 2500. The contact stated that while driving approximately 35 MPH, the vehicle went into LIMP Mode, and the message "Service Transmission" was displayed. The vehicle was taken to the dealer, where it was diagnosed that the transmission valve body rod had failed. The valve body rod was replaced. It was unknown whether the vehicle was repaired. The vehicle remained at the dealer. The manufacturer was not notified of the failure. The failure mileage was approximately 44,546.”Owner report · Power Train · Aug 2025
“When dealer took apart my rear brakes the parking brake shoe lining was un bonded from the shoe 26,000 miles and seems to be a defective part”Owner report · Service Brakes · May 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
“Shift to park message displayed while attempting to shut off engine after shifter was in the park position, accessory would not turn off even after driver door opened and could not leave vehicle.”Owner report · Power Train,Electrical System · Apr 2025
