2021 CHEVROLET TAHOE Complaints

While traveling on the highway at 65 mph the car comes to a complete stop with no brakes applies. No engine light present nor were the emergency braking lights on. This is the 4th occurance.

As a traffic crash reconstructionist, the issue is a MAJOR SAFETY ISSUE. My wife was exiting a residential driveway when the vehicle started to stutter and immediately shut down with no power or any capability to get the vehicle off the road. The shutdown caused the blockage of a residential street on a Friday afternoon, until the correct tow truck arrived. This was due to the fact the vehicle could not be moved due to not being able to start the engine nor the ability to place the vehicle into neutral, without starting the engine or crawling un der it with tools. It was determined the fuel module went bad. There was no warning of the failure of the component. Luckily the shut down of all components of the vehicle did not occur on a high speed or highly traveled road since I did not have any control of the vehicle after the fuel module failed. This is not the first report of the issue to NHTSA. Hopefully something will happen to find a fix to put the vehicle in neutral without tools, for the safety of the motoring public.

This is the second engine I’ve had replaced since I bought the vehicle in December 21, 2023. The first engine failed in August of 2022 while I was driving on the highway. The vehicle began to smoke and shut down while I was driving on the highway. The vehicle shut down and I had to use the current momentum of the vehicle to pull over to the shoulder. The vehicle would not come out of gear and would not restart. I complained of transmission problems ever since the engine was replaced. The service department escalated the concerns to the GM engineers who never gave directions to check the transmission fluid or physically check the transmission. January 24 of this year I was on the highway driving to work when the vehicle again shut down. The dash stated restart the vehicle. While in motion the vehicle was trying to shift to neutral. I informed the dealer of this message and they claim they took note of it. With the vehicle not being able to start or move out of gear the tow truck had to drag the vehicle onto the bed of the tow truck. This also occurred on the first engine failure as well.

The airbags failed to deploy in my 2021 Chevrolet Tahoe after being involved in an accident where another vehicle t-boned my vehicle on the passenger side front end to rear end causing severe damage and pushing my vehicle with great force. A police report was taken by officers that responded to the traffic accident. A claim was filed with my auto insurance and my 2021 Chevrolet Tahoe is currently being repaired as it was not deemed a total loss. Myself and my passengers were injured and received and continue receiving medical treatment for our injuries; our safety was definitely placed at risk. Before being involved in this accident, warning alerts/lamps would appear on the vehicle’s dashboard indicating to “service the safety restraint system” and also to “open then close passenger window” which in turn led me to take the vehicle in for service however the dealer said it could not be duplicated nor did the computer show any alerts. After the accident, I Contacted General Motors and filed a claim for the non deployment of the airbags, they in turn are conducting their investigation.
