CHEVROLET Complaints

I was driving with trailer attacked coming from [XXX] , in the middle of the overseas highway (a two lane steet) the truck loss power and stalled and would not start. I was only able to move slightly to the side, with half the trailer with boat still sitting in the road. My family was on board and I am alive and an accident didn't happen. I called a tow truck (took an hour to get to me) and charged me $520 for the tow. The tow truck driver said that he had to tow several chevrolet trucks with the same issue and it was a faulty fuel module. I had a mechanic run a diagnostic and the Code P129F commonly indicates a failure of the Fuel Pump Driver Control Module (FPDM) was the one coming out. I have read many customer experiencing the same issue. And in my case my trucks 3 year warranty expired November 2025 only 6 months ago.

Having a strong smell of gasoline in my garage after filling. After the garage had aired out the next morning the same strong smell. There no warning lights

I have received this warning a few different times “Steering Assist is Reduced". Which causes my vehicle to not blow cold air when AC is on. Fans are louder than normal. And when I turn off my vehicle fans continue to run for roughly around 8 minutes.

Vacuum pump failed: On May 28th, 2025 the brake pedal on our 2019 Chevrolet Equinox became very hard along with check engine light, a "Reduced Power" notification, and "Brake Assist Failure" notification. After a mechanic inspected the engine, he found that the vacuum pump had shattered. The mechanic replaced the pump with an OEM replacement from GM. On May 11th, 2026 the same exact issue happened again. 1. The vehicle and/or part is available for inspection. 2. Anyone driving or riding in the vehicle is at risk due to the difficulty of braking. 3. The vehicle/component has not been inspected by the manufacturer since the 2nd incident.

The issue is related to Super Cruise hands free driving. During a recent long trip multiple times the Super Cruise signaled for lane change and tried to move into the passing lane with a car directly beside me. I have 8,500 miles on this car and have used Super Cruise extensively on highway driving only and until this last trip never had any issue with the system seeing cars in lanes beside me before. I only avoided a collision because I prevented the lane change by grabbing the steering wheel. This software bug will end up with injury or death of individuals unless Chevy fixes this immediately. Your help in investigating this is appreciated. I will add my son has a 2025 Suburban and has experienced the car trying to pull into traffic beside him.

My vehicle OnStar telematic module has shorted out the complete electrical system. This module is backordered. No time frame was told it could be months. Many GM vehicle have the same problem. The vehicle can stop while sitting or driving. This vehicle is unsafe to drive i traded it to the dealership. They will hold on to it until(if & when) they get the part.

My cars check engine light keeps coming on and the first time it came on with an engine under boost failure and I took it to a 3rd party shop to get fixed and they had to replace the turbo charger. I paid $2500.00 for that. 2 weeks later the same light came on and they had to replace it again. Well now the light came on again after a month for the same thing and I am taking it back into the shop again. That will be 3 times.

Special coverage programs for the 2018 Chevy Traverse front exhaust pipe mounting bracket failure. GM has focused on coverage specifically on 2019-2021 models, but 2018 models are affected as well. I'm being forced to pay for a new exhaust when 2018 models should have been included for the Specific special coverage (e.g., N212356540, N222385510) exists for 2019–2021 vehicles, offering repairs (sometimes for 15 years or 150,000 miles) when the front mounting bracket breaks.
