CHEVROLET Complaints

Our Traverse has the transmission shudder really bad. This started at about 20k miles. Dealership made some adjustments which helped. Now that it out of warranty, this has gotten soo much worse. This needs to recalled.

The contact owns a 2018 Chevrolet Malibu. The contact stated that the gear shifter was intermittently stuck in park(P). The contact turned the steering wheel, engaged and disengaged the parking brake several times, per the Owner's manual instructions, and the gear shifter was able to shift out of park(P). The vehicle was taken to an independent mechanic, where the failure recurred. The mechanic was able to move the gear shifter out of park(P) after several attempts. The mechanic was unable to diagnose the vehicle and referred the contact to a dealer for assistance. The contact contacted two dealers, who advised that there was no availability for an appointment. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 89,992.

This was a 6.2L V8 that is actively under investigation and recall for model years 2021-2024. it is a part of the same GM generation of engines 4th Generation, GMT T1XX. I was not told about the active recall for other members of the generation by the dealership in which i purchased it at in august of 2025. I purchased this vehicle less than a year ago and the engine has now suffered a catastrophic failure consistent with known 6.2L issues.

The contact owns a 2024 Chevrolet Malibu. The contact received notification of NHTSA Campaign Number: 26V212000 (Back Over Prevention); however, the part to do the recall repair was not yet available. The contact stated that while driving at an undisclosed speed, the infotainment system screen glitched, displayed a green image and turned blank intermittently. Additionally, the contact stated that while reversing, the rearview camera was inoperable, and the message "Service Visual System" was displayed. The vehicle was taken to the dealer, where the contact was informed that there would be a charge for a diagnostic test, and that the warranty company would be contacted for coverage. The contact declined to pay a fee because the failure was related to the recall. The vehicle was not repaired. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the failure. The failure mileage was unknown.

I am submitting this statement to report a recurring safety and reliability issue with the 2022 Chevrolet Malibu. The vehicle intermittently displays a “Shift to Park” message when the car is turned off, even though the gear selector is already in the Park position. Due to this malfunction, the vehicle’s system does not fully shut down as intended. As a result, electrical components remain active, leading to repeated battery drain and, in some cases, a completely dead battery. This creates an unreliable operating condition and leaves the vehicle unable to start without external assistance. This issue presents both a safety and usability concern. The vehicle may become inoperable without warning due to battery depletion, Drivers may be stranded in unsafe or inconvenient locations, The system’s failure to correctly detect the Park position raises concerns about the reliability of the transmission interlock and shutdown systems. The problem appears to stem from a fault in the gear position detection or related electronic components, rather than user error. The condition persists despite ensuring the vehicle is properly shifted into Park. Given the potential for widespread occurrence and the risk of unexpected vehicle disablement, I respectfully request that this issue be investigated for a possible defect and considered for a recall or service campaign.

The contact owns a 2018 Chevrolet Equinox. The contact stated that while driving approximately 80 MPH, the vehicle unexpectedly decelerated. The contact pulled over to the closest exit and pulled over to the side of the road. The vehicle was turned off and then restarted; however, while attempting to drive forward or reverse, the vehicle failed to move. The contact inspected the vehicle. While inspecting the vehicle, the contact became aware that there was fuel leaking from the side of the engine near the high-pressure fuel pump underneath the vehicle. The check engine warning light was illuminated. The vehicle was towed to a certified mechanic, who diagnosed that the transmission intake failed, causing the transmission to fail. The transmission was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 168,053.

I am writing to report a serious and dangerous issue that occurred with my 2020 Chevrolet Malibu LT on April 27th 2026. While driving on the interstate after work, my vehicle suddenly experienced a failure that made it extremely unsafe to operate. The brake pedal became extremely hard to press, and the vehicle did not want to slow down or stop properly. This created a very dangerous situation while I was driving at highway speeds. Additionally, I noticed that nearly all of the engine oil was gone, which is extremely concerning and may be related to the failure. Based on these symptoms, it appears the vacuum pump may have failed while the vehicle was in motion. This issue placed me at significant risk of an accident and could have resulted in serious injury. I am requesting an immediate investigation into this matter and assistance with repairs. I would also like to know if there are any recalls, known defects, or extended warranties related to this issue. Please advise on the next steps as soon as possible, as the vehicle is currently unsafe to drive.

I want to start off by saying that I have taken meticulous care of this vehicle and the intention was to keep this truck forever. However, that will not be possible after this incident. I was driving the vehicle at 60 mph when I noticed smoke coming out of the back of the vehicle and at that moment, the dash cluster started warning to shut off the engine immediately due to a lack of oil. I know there was plenty of oil in the engine because I just had the oil changed at a shop two weeks prior to the incident. I was able to verify that it was a total of 22 seconds from the time I noticed the smoke to the time I was able to pull off safely and shut the engine off. At that time, the engine had not seized, and I was able to manually shut off the engine on my own. I never tried to restart the engine and I had it towed to a shop that was nearby. 48 hours later the mechanic inspected it and discovered that the oil cooling line had somehow disconnected from the engine block, which had resulted in a catastrophic loss of oil. When that repair was made, the mechanic discovered that the engine would not start either by hand or automatically and deemed the engine to be seized. The engine in question is the Chevrolet 6.2L L87 engine that was involved in a manufacturer recall for models made in 2020 through 2024. My vehicle is the 2019 model and although there have been numerous occasions that I’ve been able to find in only a short period of research that revealed similar issues with a 2019 L87 6.2L engine, there still is no official recall on my specific model year. It was 1:30 in the morning, and I was rushing my sick dog to the emergency vet when this happened. Not only did it cause a major inconvenience trying to get him there in a timely manner, but our safety was also compromised in the process.

The transmission is going out at 107K miles and needs to be completely replaced for around $8500 (see attached quote). It has a shudder and has a hard time shifting into third gear. This is a known issue with Traverses.

I am reporting a vehicle fire involving a 2020 Chevrolet Equinox [XXX] ). The fire originated in the engine compartment. The official fire report lists the causes as "undetermined", with the area of origin identified under the hood. There were no prior warning lights, mechanical issues, or indications that a fire risk was present. The vehicle was being used under normal conditions and was properly maintained to my knowledge. The vehicle was declared a total loss by my insurance company. Due to the undetermined cause and engine compartment origin, I am concerned there may have been a potential mechanical or electrical defect that was not identified. I am submitting this report in case similar incidents have occurred and to support an potential investigation int vehicle safety.
