What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
In August 2024 approaching a stoplight at 40 mph, the brakes locked, would not release, gas didn’t work, I had no control over steering this left 6-7 ft skid mark, The vehicle also had electrical issues the interior dash lights would go black, very bright, interior lights would flash, the radio would stop working.
Rake assist was needed and disabled abs and forward collision while lighting up multiple warning lights on dashboard. Lights eventually turned off leaving a check engine light on. Multiple codes pulled from system using obd2 reader. Communication bus B offline and U0074, U0151, U0447,U0452 all at same time.
I first noticed the brakes squealing in August 2025 at 15,000 miles. The dealership said I needed to resurface the front rotors. I mistook this a coating and brake debris, but it was actually the rotors warping. By 21,000 the vehicle is pulsing heavily when stopping.
Coolant leak caused by known manufacture defect in upper hose assembly causes coolant to drain and engine to overheat. CEL only comes on when coolant is almost gone. GMC refuses to cover the known issue after 36k miles.
Coolant Leaking at 22K miles, smell of coolant, check engine light on and off 2X's. Coolant evidence on driveway and in engine cabin. Known condition for GM Model. No parts available for replacement. No recall for issue.
After two weeks, check engine light finally cut on to indicate low coolant flow. Coolant reservoir was subsequently checked and found to be completely empty. It is apparent this reservoir had been extremely low / empty for at least two weeks with no warnings.
Upon starting the vehicle, I got multiple warning lights. The most important was brake failure. I had no brake function. I took it to the dealer and they replaced the brake module after 3 days.
The driver pulled over and noticed that the passenger’s side rear tire was low. The vehicle was taken to a tire shop, and it was determined that the tire damaged and the lock was missing. The mechanic located a pair of pliers between the rim and tire. The tire was replaced. The local dealer was not contacted.
