CHEVROLET Complaints

On August 25, 2026, my 2026 Chevrolet Traverse experienced a severe safety failure involving the Automatic Emergency Braking (AEB) system. While moving slowly forward in a drive-thru lane with no obstacles in front of the vehicle, the car's automated systems unexpectedly and violently slammed on the brakes.The vehicle brought itself to an immediate, harsh stop without any actual hazard present. The sudden, uncommanded application of maximum braking force caused severe physical jolting, resulting in a whiplash injury to my neck.This unexpected braking event creates an immediate crash hazard for vehicles behind me and poses a severe risk of physical injury due to violent, unprompted stops. This incident appears directly related to ongoing electronic brake module and automatic braking system malfunctions under active federal investigation. I request a thorough safety investigation and a formal recall to address this dangerous defect.

My lifter failed in my Chevy Silverado 1500 on the highway, causing severe shaking while driving and an array of dash lights. After taking it to a local. Chevy dealer, they confirmed a lifter collapse and possible damage to my cam shaft. I have been up to date on all oil changes with premium synthetic oil, and there were no prior dash lights indicating a problem.

I am reporting a serious safety issue involving my 2026 Chevrolet Equinox. While I was driving on the highway, the vehicle suddenly shut down and became completely immobilized in a travel lane. I was unable to move the vehicle out of the lane or shift the transmission into Neutral. This created an extremely dangerous situation, and a truck nearly struck my vehicle while I was stopped in the roadway. The vehicle had to be towed to a Chevrolet dealership. It has now been at the dealership for three days, and as of this complaint, the dealership has not been able to determine the cause of the failure. I am extremely concerned that the vehicle suddenly lost power while being driven and could not be moved to a safe location. I believe this presents a serious safety risk to the driver, passengers, and other motorists if the failure occurs again. I have also opened a case with Chevrolet/General Motors regarding this incident. I am requesting that NHTSA document and review this incident as a potential vehicle safety defect.

45,000 Mile 2022 Chevy Silverado 1500 LT - Vehicle began rough shifting, slipping gears, failing to engage into drive, and shuddering at constant acceleration. Transmission valve body failure and replacement needed - confirmed by certified Chevy dealer. Awaiting receipt of warranty valve body from GM, but part has not been released by GM - estimate from dealer is 5+ weeks for receipt of the part based on recent experience with another customer requiring the same repair.

July 11, 2026 I experienced a lifter failure. Towed to GM dealer on July 13th. Dealer comfirmed lifter failure and camshaft damage and metal contamination throughout engine. Dealer installed replacement engine using my mechanical breakdown policy since I was out of factory warranty. Picked up truck one month later with new engine and the transmission started slipping and shuttering. Took back to dealer who claimed metal fragments in fluid and said transmission needed to be replaced. I then made a second claim on my mechanical breakdown policy and the dealer replaced the transmission. All of these issues are known issues with the engine and transmission.

When vehicle is idling the cabin shaking/vibrating. When engine is warm the sound of engine goes away and when it is cool the sound and vibrating comes back.

In my chevy equinox 2018 my vacuum pump and brake booster failed when I was driving and I could not brake. I slid into the gravel side of the road on the 138, luckily there were not alot of traffic at the time cause I would have caused a major accident. Never had any braking issue till now. Now this is a major financial hardship on me to fix this issue that should have not happened if it got recalled to fix this issue on this certain model. No lights, no indicator lights or anything came on either which was scary. And I have no problems or any other issues with the equinox. It just failed all of a sudden.

Was on a trip and on the highway home the service break lights came on. By the time we got home(less than 200 miles) the breaks where scraping the calipers. Truck only had 25,586 miles on it when they picked it up to take to the shop. Dealership had to replace the break pads, calipers and rotor on the front driver side.
