CHEVROLET Complaints

While driving on the highway, I heard a loud pop that made me flinch and swerve. After parking I noticed the glass in the sunroof had exploded upward like a volcano, leaving a large hole. Fortunately the shade was closed, or glass would have come into the car while I was driving.

The vehicle accelerated without input and the brakes failed to respond. I am notifying you that this vehicle is a life-threatening safety risk and should not be rented again until a master technician clears the electronic throttle control and breaking system. This condition presents a serious safety risk and could lead to a car crash or injury. Additionally, the vehicles, climate control system behaved erratically, alternating between extremely hot and extremely cold air without adjustment. This may indicate a broader electronic or system malfunction affecting vehicle city.

I purchased a 2016 Chevrolet Tahoe on March 8, 2026, in [XXX] . After the sale, I discovered that the vehicle has serious undisclosed safety defects, including evidence that the airbag (Supplemental Restraint System) had previously deployed and was not properly repaired or restored to working condition, and were actually cut and removed from the vehicle and glued and covered up. This defect was not disclosed prior to purchase and represents a significant safety hazard. It is available for inspection. This put my safety and others at risk because if I had not noticed that the airbag system was not working and was removed and if I had been in a wreck who knows the injuries that me or somebody else could have sustained. The problem has not been confirmed or reproduced by anybody other than me I have physical documentation pictures and diagnostic reports showing the issue. The vehicle has not been inspected by police manufacturer or insurance as of yet but will be completed in the very near future. There was an airbag warning light on on the dash of the vehicle when I purchased it my assumption that it was just an error or a warning since I knew that the vehicle had been in a minor incident but I would’ve never thought that all of the airbags would’ve been cut out and hidden in the vehicle. Through my own investigation, I also located what appears to be the seller’s Facebook Marketplace account, where he has dozens of vehicles listed under a personal profile. This suggests he may be operating as an unlicensed vehicle dealer (curbstoning) and potentially selling multiple vehicles with undisclosed defects. I have attempted to resolve this matter directly by sending a formal demand letter and allowing time for response, but the seller has failed to respond or offer any resolution and has ceased communication. I have documentation and evidence including photos, videos, messages, and screenshots of vehicle listings that support these claims.

Driving down the road and had Stabiltrak disable and power steering go out, causing great difficulty to maintain control of steering the vehicle. My teenage son’s first vehicle and he was driving with myself and younger son as passengers. This could have been a very horrible situation. Apparently this is a pretty widely discussed and common issue with this vehicle make (a quick google search proves this), and actually was recalled in the previous year model for this exact issue (reference NHTSA #21V213). The issue was evidently not sufficiently corrected in the 2016 year models. This is obviously a safety issue that could lead to severe injury or death and should be taken seriously by the manufacturer.

The vehicle losses power on high speed, check engine comes on, low propulsion massage displays. Vehicle does not charge. Issues similar to the investigation DCS6812.
