CHEVROLET Complaints

Concerned about the 10 speed transmission and the rear wheel lock-up , and how to obtain a extended warranty to cover this if trouble arises from issues with 10 speed transmission issues

While driving my 2021 Chevrolet Tahoe at highway speeds (approximately 60 mph), the transmission suddenly malfunctioned due to what the dealership is telling was a valve body failure. Without warning, the vehicle lost proper propulsion and began to decelerate rapidly in active traffic. I did not receive adequate warning before the failure occurred. The sudden loss of power at highway speed created a very dangerous situation. Vehicles behind me had to brake abruptly, and I was nearly rear-ended. This presented a serious safety risk to me, my three children, and surrounding drivers. The issue was later diagnosed as a transmission valve body failure. A failure of this nature should not occur on a relatively new vehicle, and there Is currently a recall on other 2021 Tahoe’s for this same issues. My car is sitting at the Chevy dealership waiting for a full valve body replacement, which the dealership said they are having issues getting the part and will take over 2 weeks. The cost is around 5k to fix.

The vehicle will hard brake on its own while going down the freeway, no blockage of the camera or vehicle in front when it happen

The 2024 Trailblazer developed a problem going into reverse at less than 17500 miles in December of 2025 when my daughter came home for Christmas. It would slam into reverse or freeze and then shift harshly. The selling dealer replaced the valve body in the transmission while it was in for normal service, the valve body was on order for 30 days in January. After I delivered the car back to my daughter on January 26, 2026 which was 4 hours away in Northern Virginia the transmission continued to freeze and slam into reverse. The selling dealer advised not to drive it back to Virginia Beach, VA. The car was then dropped off at an Arlington, VA dealer and was there for 9 days. The servicing dealer said they could not duplicate the situation and returned the car after 9 days. My daughter stated that the transmission has continued to act up in reverse with freezing and slaming while trying to reverse in real world settings. The Trailblazer was dropped off for a 3rd time on Saturday, February 21st and since then we have not heard a word from the dealer. I called Chevrolet Customer Service and they assigned a case number to the problem with the transmission. The case number is 89420437 and Sarah at Chevrolet said she would be in contact with my daughter by Sunday, March 1st.

Vehicle accelerated while driving. The RPMs gage turned red; however, the vehicle stopped in the middle of the road with other cars coming. After the vehicle came to a full stop it would not move. Finally it started moving slowly and I was able to get off the road. When the tow truck arrived the vehicle would only go forward. No reverse. Error message on dashboard picture attached

The contact owns a 2022 Chevrolet Bolt EUV. The contact stated that while driving at an undisclosed speed, the electrical system became inoperable. The contact stated that the seat belt warning chime failed to function when the seat belt was not fastened. Additionally, the instrument panel became inoperable while attempting to reverse, and the rearview camera failed to function properly. The vehicle was taken to an independent mechanic, but was not diagnosed or repaired. The vehicle was then taken to the dealer, where it was diagnosed, and it was determined that the radio system and instrument panel screen had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 50,000.

-Transmission failed. - Driving down the highway and the truck just quit. (Morning rush hour traffic) -truck was towed to my mechanic -only made a weird noise the day before.

The drivers side, female end, of the seatbelt comes undone when cold. This is reproduced every single time it is cold for approximately 5 minutes of driving until the inside of the vehicle warms up. This happens with both primary divers of the vehicle. We took it to the dealership we bought it from but because there is not a current recall and they cannot reproduce the issue since our current temperature is in the 40s, they won’t replace it under warranty. No warning systems go on when this happens while driving.
