CHEVROLET Complaints

The automatic transmission on my 2021 Chevrolet Tahoe (gasoline engine, 10-speed 10L80 transmission) has been exhibiting intermittent slipping/skipping during gear changes, particularly during acceleration and deceleration. The transmission component is available for inspection upon request. The malfunction poses a safety risk as the unexpected hesitation and rough shifting creates unpredictable vehicle behavior at highway speeds and during merging, increasing the risk of a collision with other vehicles. The problem has not yet been formally confirmed by a dealer or independent service center, however a knowledgeable automotive advisor has assessed the likely cause as moisture contamination of the transmission fluid, which degrades lubrication and causes erratic shifting behavior, known issue in several GM vehicles, but the only recall related to this issue is for just Diesel vehicles. I contacted General Motors customer service regarding this issue and was directed to file this complaint with NHTSA, as GM stated they were unable to attach or create a related existing recall to my vehicle. The vehicle has not been inspected by police, insurance representatives, or the manufacturer at this time. I am in the process of scheduling service at a transmission specialist. No warning lamps or dashboard messages appeared prior to or during the shifting malfunction. Symptoms first became noticeable at 85,000 miles, and have continued since.

I am reporting a severe mechanical failure involving the fuel pump module on my 2021 Chevrolet Equinox. My vehicle exhibits symptoms that match NHTSA Recall Campaign 23V-013 / GM Campaign N222372310 (Inadequate Fuel Pump Flow). However, when checking my VIN, GM indicates my vehicle is currently excluded from the official recall population. My car hesitates to accelerate on the highway, will randomly sputter when at a constant speed, I have had a checked engine light come on which was cleared after it being inspected but was not fixed. This creates an extreme hazard and risk of my car completely stalling, or the risk of an accident when trying to accelerate on the interstate or just merging with the traffic flow. Given that the symptoms and component failures on my vehicle are identical to those documented in NHTSA Campaign 23V-013, I request that NHTSA investigate an expansion of this recall to include additional 2021 Chevrolet Equinox models. Additionally, I request General Motors cover the cost of diagnosis and repair under safety recall warranty provisions.

The contact owns a 2014 Chevrolet Impala. The contact stated that while driving at an undisclosed speed, the messages "Stabili-trak" and "Power Steering" displayed on the instrument panel, and the traction control warning light illuminated. Additionally, the transmission display switched from drive(D) to park(P) while driving, causing the vehicle to decelerate and stall. The rear-view camera also intermittently failed to function properly, displaying the message "Park Assist Not Available" while reversing. The contact pulled over, waited, and then restarted the vehicle. The contact stated that the wheel hub, camshaft sensor, and a cylinder had previously been replaced, but the failure persisted. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure. The failure mileage was unknown.

There was a sent out that GM dealers needed to at no cost provide the software update to several vehicles due to a software issue that puts out an emergency warning that the brakes are wearing and are critically low when in fact they are not. Without the new software vehicle owners cannot manually reset the notification even after changing their brakes. I recently took my truck to David Chevrolet who advised me I needed to pay $193 for this software update which goes against the notice from GM and the DOT. I’m now driving without my brake monitoring system on because the dealership will not update my software. I’m filing a complaint because I should not need my brakes changed again by the dealership as I have already replaced perfectly good brakes because I didn’t know there was a software problem. My vehicle is well under the 36k mile and is only two years old.

Loses oil between oil changes. No visible signs of leaks or odor of burning oil.

On the transmission for the 8-speed I'm wondering why mine hasn't been recalled when all the others have been recalled were made the same basically time. And I'm having the same issues as those other transmissions

The contact owns a 2014 Chevrolet Cruze. The contact stated that while attempting to move the gear shifter, the vehicle hesitated while shifting into neutral(N) or drive(D) as intended, and there was an abnormal sound coming from underneath the vehicle. No warning light was illuminated. The contact stated that the failure had reoccurred. The vehicle was towed to a local independent mechanic, where it was diagnosed and determined that the transmission needed to be replaced. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 45,000.

Transmission failed at 38,000 miles. Downshifted violently while driving and couldn't keep up with the 35mph speed limit. Was luckily not on a highway or far from home. Dealership noted it's a common valve body issue in the transmission. No inspections, vehicle has a branded title (hail) and Chevy claims no responsibility for the transmission failure. 0 warning signs or issues.

Car was going into neutral unexpectedly with a message of "two gears selected". Very disorienting as with the one pedal driving mode I was expecting the car to slow and kept moving faster than expected. Luckily nothing happened as I jammed on my breaks. I was reversing towards a hill in my yard that leads to some woods Brought the car to the dealership, and they said the transmission control module failed after 3 years 9 months in service and ~48000 miles. Paid $2000 as it was not covered under warranty

My 2020 Chevrolet Trax has experienced recurring brake problems for approximately two years. The issue involves the brake pedal becoming unusually resistant and the vehicle failing to brake normally when I apply the pedal. The vehicle and affected components are available for inspection. My first known documented occurrence was August 21, 2024, one day after I picked up the vehicle from AutoNation Chevrolet. I had dropped it off July 29, 2024, and picked it up August 20, 2024, after it was diagnosed and repaired for reduced-power issues, including shaking while driving. On August 21, 2024, I was driving normally when I attempted to brake. The brake pedal suddenly became resistant and the vehicle would not stop normally. I repeatedly pressed the brake pedal without resolving the problem. I pulled the emergency brake and waited. Approximately five minutes later, the dashboard displayed a “Service StabiliTrak” warning, along with the ABS and check-engine lights. After the warning lights appeared, the brakes began functioning normally again. This is the first occurrence I personally documented on my phone to my knowledge. Over the past two years, I have taken the vehicle to the dealership and/or Big O Tires approximately 15 times for service and repairs, including work I was told could help resolve the issue. These visits also included routine services such as tires, oil changes, and emissions testing. Despite repeated service and recommended repairs, the brake problem continues. The vehicle is currently at the dealership as of August 11, 2026, being diagnosed for the same recurring brake issue. This problem has repeatedly placed my safety, the safety of my 6-year-old child, and the safety of other drivers and pedestrians at serious risk. The intermittent loss of normal braking makes it difficult to safely stop or avoid a collision. I have repeatedly sought professional assistance, but the underlying issue has not been permanently resolved.
