2021 CHEVROLET TAHOE Complaints

I was driving with family (2 adults - including myself, and 5 kids - ages [XXX] ) The truck started to flash warnings and my brakes disabled. We couldn't stop and almost had an accident. I kept pumping the brakes and the E break I didn't give it any gas and we slowly came to a stop after some time. I shut the truck off as I was beyond terrified and tried to start it back up. The lights came on but it didn't turn over to start. Had to have it towed and find an uber for a 7 passenger car. The truck was towed to the nearest dealer (a little over an hour from my home) and I was told it was a battery issue. They replaced the battery didn't check the breaks and told me if the battery dies the breaks stop working. Yet, I had power in the truck just no brakes, when I tried to turn it on the lights went on as did the radio but that was it. I tried to take pictures of the warnings on the dash however we were in Mom panic mode. Chevy is acting as if this isn't an issue. I had to put out over $1,100 between the battery, the fees of the dealership, rental and an uber. If we were going at a higher speed we would have not been okay. It was beyond dangerous and the thought that if a battery suddenly dies you have no breaks, that is just unacceptable. I would love for someone to look into this. I am now looking to see what I can do as I don't feel safe in the truck. I don't want this to happen to anyone else hence why I am asking for someone to please look into this.

Sunroof continues to collect water in the drain. I have had it blown out but it continues to happen. It is a matter of time before it begins to leak into the truck. In my research, this is an extremely common problem/design flaw.

The contact owns a 2021 Chevrolet Tahoe equipped with Good Year Tires, Tire Line: Wrangler Trail Runner AT, Tire Size: 275/60/R20, and DOT number M6W0JA3R3121. The contact stated that while entering her driveway, the driver's side front tire, wheel, and hub detached from the vehicle and crashed into an unknown parked vehicle located in the driveway. The contact was unconscious for a period of time, and she woke to the vehicle sliding against the parked vehicle and garage. The contact stated that she was unconscious, but no medical attention was provided. There were no reports of air bag deployment, fire, or a police report filed. OnStar notified her that her front driver's side tire had a problem. The contact's neighbor, who is an independent mechanic, stated that the tire broke and detached. The contact called a local dealer, but the vehicle was not diagnosed or repaired. The manufacturer was not contacted. The approximate failure mileage of the tire and the vehicle was approximately 14,200.

WHAT FAILED: Main Radio. SAFETY CONCERNS: GM sent an over the air update to car around July 5, 2024 and the update broke the whole radio system to my car. I now have no access to OnStar, bluetooth for phone safety, maps, blinkers on side mirrors, radio etc. Dealer mentioned it is a very common problem with this particular GM product and the over the air update to cars. When I asked to turn this feature off so it doesn't happen again it is not an option. The Chevrolet Dealer and a sound system specialist has inspected vehicle. Sound System specialist said this part may only be replaced by the dealer as it is the high end radio system. There was no warning of the update happening. The car was in great condition until this update was pushed through in the middle of the day. Now I am being quoted $2000 to fix it with no guarantee that it wont happen again.

The contact owns a 2021 Chevrolet Tahoe. The contact stated while driving at various speeds on several occasions, there was a banging sound coming from the engine compartment. The vehicle was taken to a dealer where it was diagnosed and determined that the cam lifters needed to be replaced. The contact stated that the failure reoccurred two weeks later. The manufacturer was notified of the failure. The failure mileage was approximately 11,400.

Gps/onstar module not working, I read a lot of people are complaining same thing. I had it for a year, warranty done but I never used it. Sad you spend $70k on a truck and onstar goes bad and you never used it and they want more money to replace it. Now engine light is on.

Other vehicles of my year and make were recalled. My car was manufactured 8/14/21. I was driving on 6/12/24 and my Car died. I had power. I had fuel but fuel was not getting to the engine. It turns out it was the fuel pump control module that many others were recalled. This could have been a very unsafe situation for me as it died in a traffic lane during morning rush hour. It would not start back up for me. My dealer diagnosed it very quickly and is repairing it in 2 days time. Had I been on the freeway, someone would have rearended me. My car has 22,000 miles on it.

I am experiencing loss of power just like the recall shows for campaign 22V036000 powertrain. Engine stall in the middle of the street just like it shows for the fuel system 21V73 9000. I have stalled in the middle of the street including today four times and a month. The dealership can’t seem to find what’s wrong. Nor other places. I don’t think they are looking hard enough at the dealership. I almost got killed by another car going at least 65 mph while I was stuck in the middle of the street at a stoplight. These are all different days. While working and people in my car.

I was driving to work today and I heard what sounded like an explosion, so I stopped and pulled to the side of the road and checked everything and I seen that the sunroof glass was broken, I have only ever used the sunroof twice and that was to see if it was working. My safety and others on the road were at risk because if I would have had the sunroof sliding shade open the glass would have fell on my head or in my face. Also anyone driving behind me I'm sure the glass flew on their vehicle and could caused an accident. I got to work and called the local Chevrolet dealership in town and they said there were no recalls for this problem, but yet I looked it up under GMC forums and there has been other people saying it happened to them, especially the same year and make and model. My vehicle has not been inspected by the manufacturer, police or insurance yet, I reached out to the Chevrolet dealership and they said there was nothing they could do to help because there were no recalls on my vehicle, so I asked the girl in the service department who was higher then her and could help me because I did nothing wrong and did not feel that I should have to pay to fix this problem. She then gave me customer care contact information and I am waiting for a response. There were no warnings or symptoms or any messages on the dash, my sunroof glass just exploded without any warnings.

When turning left in cross traffic, the truck stalled. It would crank and try to run, but not start as it wasn't getting any gas. The gas tank was full at the time. The failure was very similar to when I was stranded with the fuel issue in 2021 a couple of months before the recall for the fuel pump failure was issued (NTSA # 21V739000). Fortunately, it did start momentarily so that I could get out of oncoming traffic so that I wasn't t-boned. I was able to get it home, but it failed multiple times in the 8 mile trip back to the house. We will not drive this vehicle as it is unsafe to drive and now we are left to tow the vehicle to the closest dealership which is 50+ miles away. It seems this part only works a few years and then fails.
