Instrument panel has failed twice and is unresponsive. The gauges move and stay to the left after moving left to right. All lights begin to cycle through error messages. I have video of the issue both times it happened. When it occurs, you don't know your speed you have to guess, the full tank reads empty etc., and it is dangerous to back up. The vehicle has been diagnosed by one independent mechanic and is currently at the dealership. There was no warning before the instrument cluster failed other than a cycling through of warning messages service transmission check 4X4, service suspension system, service Power Steering Drive with care. -The center screen goes in and out. -When in reverse, the rear camera is black, the screen blinks intermittently. - Dealer has stated that the wires are put on incorrectly- if that is the case, I am not sure who would have done that other than the manufacturer. -previously reported there was a strong gasoline smell in the cabin that made it really hard to breathe. Dealer corrected. Right passenger side is intermittently wet with no cause from the interior creating stale smells, making it hard to breathe. It is important to note this is the side where the electrical wires are "put in incorrectly" according to the dealer. I also have a video of what occurs

2 incidents of complete engine power loss while driving. Luckily was able to roll off road safely to curb. Dashboard glitch/flashing multiple/various message, including check engine, conditions not ideal to shift, etc. Would not re-start/shift when attempted. Tried disconnecting battery cable completely and re-connecting and that seemed to 're-set' the system and engine re-started. Incidents were about 30 days apart. "This battery reset" was tried because approx 1 year prior after leaving Tahoe parked at airport for a 7 day trip, it would not start, completely dead. Battery charge/jump would not work...watched youtube videos and someone said to try disconnect/reconnect cable and it worked to start it up at that time & did take it into Dealership after that incident and no-cost repairs were made for that issue. Called Chevy 3/25/25 on this power loss while driving issue to ask for information/assistance, they advised to take to dealership for diagnostic info/report and depending on result/cause might assist with costs to repairs. Appointment set for 3/28/2025 with Salem Oregon Chevrolet.

I have taken this vehicle two times to the dealers that sell Chevrolet. The first time it was there for 5 hours and nothing was done and the second time the service agent said there was no recall on this vehicle when obviously there is one.

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.

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.

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.

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.

Purchased a 2021 Tahoe in late 2020 - May of 2021 the car started leaking water during a rain storm into the main cabin. Brought it to the dealership and they couldn't find any issues. Fast-forward to 2023 and it happened again in May and June. Brought the car to dealership and was told that the sunroof drains were clogged and it's a maintenance issue. I contacted GM and after about 2 months they had a field tech look at it....found that it wasn't a maintenance issue but a sunroof drainage tube that was installed incorrectly. I received an email saying that they would replace the tube and front carpet but I need to pay 50% of the bill. All the carpets and roof liner have been affected by the leaking and the car smells like mildew. I would expect them to at least replace everything and pay 100%. If they were responsible they would take the car and replace it with a new car for me. I purchased a $65,000+ vehicle with a factory defect that has caused water leaking into the car and i don't know if there will be future issues with electrical or mold.

water leaking in from the roof area. I heard water above me, then after applying the brakes water came pouring in through the LED lights, seat belts, and other areas mostly on the passenger side of the vehicle. After pulling panels and looking, water was dripping down into the car getting airbags wet, the fuse panel, seat belts are soaked, carpet, and water inside LEDs and dripping on other electronics. Dealership unable to locate leak at this time and is a continuing problem.

My tahoe has shut off several times. I am sometimes at a red light and it shuts off and won't turn on or itll eventually turn off but it has a ton of errors on the screen. This has happened about 6 times. Today, April 6th, it wouldn't even start. It has started at the dealership but the screens are blacked out. Also the back hatch is not working as well and it randomly happened. I just purchased this vehicle in September of 2022. And it only has about 40k miles on it. The first time it shut off on me it had less than 40k miles.

I have an on going problem with the emissions system on my 2021 Tahoe. The vehicle discharges raw diesel fuel and DEF from the exhaust tail pipe during cold startup. This discharge is overwhelming and is so strong it can be detected by smell from over fifty feet away. In addition to this issue the fumes enter the inside of the vehicle and at times it is so bad you need to open the windows. I believe this problem is unsafe as it poses a fire risk and a CO exposure risk to the vehicle occupants. The vehicle has been in the shop repeatedly for the past eighteen months with various parts replaced. To date none of the repairs have fixed the problem. In February GM issued a statement saying that this is normal operations.

While driving on the highway there was a loud explosion like sound. The sunroof on the SUV completely shattered. There was no car in front of me and no overpasses. Sunroof shattered and glass came in the car. I was driving the speed limit which is 70MPH and there was no forewarning. GM is scheduled to look at the vehicle, I am waiting on their return call.

Received an Over-the-Air update that rendered my vehicle unless. My vehicle would no longer start, or power on, or power on in accessory mode. It was stuck in Park, the electronic Parking Brake could not be disengaged, the door locks could not be operated and left unlocked, no lights, no warning lights, the emergency lights did not function, no horn, and most everything else. The only things still working were the radio, the driver's side powered seat would move, and the light came on for the Parking Brake. The battery was fully charged. I also started receiving messages through my Chevrolet APP that the vehicle had no air in the tires, no oil in the engine, and many other items that needed servicing. I am not sure what exact components or computers have failed yet. GM could not find any dealer to render aid and come to my location to reprogram the vehicle. It had to be towed to a dealer. With the electronic Parking Brake engaged, GM had a hard time trying to find a tow truck that wouldn't just drag the vehicle down my driveway and onto a flatbed.

On 7/13/2022, I was driving down the highway and my Tahoe without any warning began to decelerate. I put on hazards and merged over in rush hour morning traffic off to side of the highway. I looked to put it in park and it had switched itself into Neutral. I immediately shut the car off and tried 3-4 times to start it. Had to wait 5 minutes then got it started and back on road I went. The previous evening, the My Chevrolet App showed I had a flat driver side rear tire but in fact, I didn't.
