Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The air conditioning system fails to cool. My vehicle only has 47,000 miles on it currently and is well-kept. A professional garage inspected and advised that there was a leak in the refrigerant system. I contacted my local Chevrolet dealer Jeff Gordan Chevrolet where I purchased the vehicle new and they said the issue was not under warranty and that my warranties had expired. They would not repair the air conditioning system at no cost to me, the owner.”
NHTSA complaint #11730381, filed 2026-04“I got in my vehicle and turned it on. Once on, it asked me to roll down my passenger side window and roll it back up. I thought that was odd, but did so. My vehicle had completely reset. The clocks were not correct and none of our controls were set. I reset everything, but thought that was weird. A few days later, my husband and son were coming home from a 5-hour trip and as they were turning into our driveway, thank God they were home, the vehicle completely turned off and shut down. The brakes locked up and they came to a complete stop. …”
NHTSA complaint #11767621, filed 2026-09“When I make turns/curves my Tahoe will periodically lock the wheels on the opposite side and pull our vehicle to the other lane of travel. I’ve noticed previous recalls on other Tahoes for the same thing and the delearship claims they can’t replicate the problem and our vehicle is not included in that recall. I have had the vehicle in Auto and 2wd and it continues to happen. I can disengage the 2wd to auto and vice versa and it sometimes feels to help the problem. I have also disengaged traction control and that will seem to help as well. This has been happening on and off for over a year.”
NHTSA complaint #11515092, filed 2023-04“Rear view camera goes off starts with striped blurry lines then goes to blue screen says “service rear vision system”. Took to dealer battery tests low. They recommend replacing battery, positive and negative cables to the tune of $1000. They aren’t positive this will fix it they say this is what they start with there are several errors codes with that system message. Not covered under extended warranty because they say it’s wear and tear/maintenance. Haven’t had issues with the battery just the rear view camera system. 2020 Tahoe LS 3 yeas old. Battery shouldn’t be bad this soon. …”
