CHEVROLET Complaints

The failure involves the powertrain, specifically the 10-speed automatic transmission and its internal Transmission Control Valve (TCV) located within the valve body. The transmission has failed, and a GM dealership determined that the entire transmission requires replacement. The vehicle is currently inoperable, and the transmission is available for inspection upon request. My safety was put at risk due to abnormal transmission behavior. GM issued a recall for this vehicle related to excessive wear of the Transmission Control Valve, which can cause abnormal downshifting and, in some cases, wheel lock-up during downshifts. Sudden or unintended downshifting at speed presents a serious safety risk to the driver and others on the road. The failure has been confirmed by an authorized GM dealership, which diagnosed the transmission failure and stated that a full replacement is required. The vehicle has been inspected by the dealership, and the recall remedy was performed in July 2025. The recall consisted of a software update to monitor excessive TCV wear, not a mechanical repair. Prior to the complete failure, there were repeated warning signs, including check engine warning lights. The vehicle was brought to the dealership multiple times in March and April 2025 for check engine warnings. After the recall software was installed in July 2025, the vehicle was serviced again in September 2025 with no issues noted at that time. The check engine light returned in November 2025, and on November 11, 2025, the transmission failed completely, rendering the vehicle unsafe to drive. Despite proper maintenance and multiple service visits addressing warning indicators, the transmission failed prematurely at approximately 74,000 miles. Given the known recall related to excessive TCV wear and the nature of the failure, this appears to be a defect-related powertrain failure rather than normal wear and tear.

Onstar telematics control module not working. Dealer says part is in back order. Some vehicle safety features are not available. GPS not available. When my phone is connected via android auto my GPS some times show my location as being in New Jersey while I'm actually in New York and nowhere close to the location shown.

The contact owns a 2014 Chevrolet Traverse. The contact stated that while driving at an undisclosed speed, the vehicle lost motive power. The message "Engine Power Reduced" was displayed. After waiting 20 minutes, the contact was able to restart the vehicle. The vehicle was diagnosed by the contact's friend, and it was determined that the clock spring had failed and needed to be replaced; however, the contact related the failure to NHTSA Campaign Number: 14V614000 (Electrical System), but the VIN was not included in the recall. The manufacturer was made aware of the failure and advised the contact to file a complaint with the NHTSA Hotline. The failure mileage was approximately 195,000.

While driving, the vehicle has repeatedly experienced sudden loss of power and electrical failures without warning. During these events, the dashboard flickers, warning messages appear, and the vehicle shuts off or goes into reduced power mode. When this occurs, steering becomes extremely difficult, braking becomes stiff, and the vehicle cannot accelerate. These incidents have happened multiple times in different driving situations, including: At stoplights While pulling into intersections Backing out of parking spaces Driving on public roads, including dark rural roads Driving with my three minor children in the vehicle On at least one occasion, the vehicle shut off while pulling onto a road with oncoming traffic, leaving us stopped in the roadway with no power and limited steering/braking. This created an immediate and serious risk of collision. The vehicle eventually restarted after several attempts. The problem has occurred repeatedly over many months. Multiple independent repair facilities have attempted to diagnose and repair the issue, but no definitive cause has been identified, and the failures continue. The vehicle has had numerous electrical, sensor, engine, and powertrain-related repairs, yet the loss-of-power events persist. Because the vehicle can suddenly shut down while in motion and compromise steering and braking, I believe this is a serious safety defect that could result in a crash, injury, or worse.

- The telematics module is bad, resulting in vehicle having no connectivity (GPS, entertaintment system, updates) - The car has no other means of hands-free operation for navigation software (no CarPlay or similar phone projection technology) - GM is unable or unwilling to supply the parts for warranty repair. - It is illegal to use the phone while operating vehicle in my state (Florida)

My Tahoe was making a loud noise, I took it to the dealer to look at it and they said I need to replace the rear driveshaft to the tune of $4000. I don't have $4000 to spend on this. This Tahoe is only 4 years old and was supposed to drive us to Minnesota next week for Christmas and now that is not possible. This is a known issue and a recall, but my VIN not included in that recall. How can this happen - you know it is a known issue in these cars!

The contact owns a 2021 Chevrolet Tahoe. The contact stated that while driving 20 MPH into the driveway, the engine seized. The contact stated that the service traction, service ESC, and engine warning lights were illuminated. Upon research, the contact associated the failure with NHTSA Action Number: EA25007 (Engine, Engine and Engine Cooling). The vehicle was towed to the local dealer, where it was diagnosed, and DTC: P0300, P050D, and P0302 were retrieved. The vehicle was not repaired. The manufacturer was notified of the issue and offered to help with the cost of the repair. The approximate failure mileage was 64,572.

Beginning in May 2025, my 2025 Chevrolet Traverse began exhibiting a false “rear liftgate open” condition when the liftgate is fully closed. This defect triggers a continuous audible alarm that occurs before every drive and persists for the entire duration of the drive, stopping only when the vehicle is turned off. As a result of this defect, the rear windshield wiper and washer are disabled, eliminating rear visibility during rain and snow. The vehicle alarm system also cannot be armed, creating a security risk. The continuous alarm causes significant driver distraction, and the loss of rear visibility impairs safe operation of the vehicle, particularly in adverse weather. Minor children are frequent passengers, and the defect has occurred while they were in the vehicle. The vehicle has been presented to an authorized Chevrolet dealership on four separate occasions for the same issue. Multiple repair attempts, including diagnostics, software updates, component replacement, and latch assembly replacement, have failed to correct the defect. Because the alarm cannot be armed, the vehicle was left unsecured and was subsequently broken into, resulting in theft of personal property. General Motors has been notified and declined repurchase, directing me back to repeated diagnostics despite the unresolved safety-related defect. Problem Category: ? Electrical System ?

On 02-07-2025 I had just got on I-95 North In Daytona Beach, FL. While accelerating to merge with heavy fast traffic I reached a speed of Approx 65 MPH. I moved into to middle lane to allow the merging traffic from the LPGA West ramp entrance. At that moment my car was engulfed in smoke the engine stopped running and I had to navigate to the shoulder surrounded by fast moving traffic very dangerous event but I made it. l immediately got out of the truck as I though is was on fire from all the smoke. After several minutes the smoke decreased and there was oil spray all over the underside of the vehicle from front to rear. The Truck had a total of 64000 Miles since new and the diagnosis was from local Chevy Dealer was The Oil Cooler Line came off, the main bearings spun causing the engine to lock up. End result was I needed a complete engine replacement at a cost of $12,689.60. I have had my truck serviced by a GM Dealer so one would think they would check the oil cooler lines when they do the inspections and routine servicing. Long story short the truck was out of warranty by 4000 Miles and I reached out to Gm customer service and after many weeks they agreed to pay back $4441.46 of the $12,689.60 which was something but I guess they really didn't have to because it was out of warranty. I really just told me that they do not stand behind there products. The real kicker is the remanufactured engine that they put back in came with a better warranty than the original now has 36 Month 100000 miles. I consider myself very lucky to not have caused a very fatal accident trying to get off the interstate that day and I am thankful for that. But this event was caused by a $150.00 Oil cooler line. Now I just drive in the right lane because of that experience.

In January 2024, I experienced an engine failure in my 2021 Silverado with the 6.2 Engine. My VIN was not part of the recall affected VIN units built in 2021-2024, it seems to have been built a few months before the last affected group, In any case, I noticed the engine stumbling, and the check engine light came on. I was able to drive the truck home, and when I went to start it the next day, the check engine light was off, so I drove it, and the engine stumbled the check engine light came back on, so I took it to the dealer. They read the codes, and cylinder 5 was misfiring. When they put a scope in that cylinder, the cylinder walls were scored, and there was oil in the cylinder. At that point the dealer chose to replace the engine with a remanufactured engine with no additional warranty added, or any other remuneration for the inconvenience. They did not share with me any specific reason (Lifters / Camshaft / something else) for the engine failure.
