Failed OTA Update to information center (Radio) has caused radio unit and screen to become inoperable. Blinkers do not sound when on, warning sounds when backup camera are in use no longer work, along with cross traffic warning due to this. It should be noted we did not consent to the OTA update, and would have not wanted the update as it has caused damage to this system. GM know this is an issue and has refused to fix this.

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

Fuel module failure while driving, engine stalled and would not restart.., while at highway speed. Very dangerous situation!!!!! Tahoe was towed to dealership kept for. 1day. Chevy dealer replaced fuel module. We have owned 6 different Tahoes starting with the year 2015 to 2024. The fuel module failed on the 2021, 2022 and now the 2023!!!!!!! Makes us question if we should purchase a new Tahoe every other year? Seriously considering other car brands such as Ford, BMW or other more reliable brands!!!!

On 2 occasions the dash lights and gauges do not turn on when the vehicle is on. The first time this happened I was driving and was no longer able to see my speed or any other details provided by the gauges. We changed the fuse and it seemed to work for 1 day. The next day I turned the vehicle on, was able to drive but none of the dash features were functioning again. Will be taking to dealership when available scheduling to have it evaluated.

vehicle infotainment system will randomly "restart" or shut off completely when vehicle is being drove, but will still be playing music also all time and temperature (outside temp) will freeze when this happens. it also make the battery drain when this happens. the only way to get the screen to come back on weve tried is to disconnect battery. weve replaced the battery, weve had a chevy dealership look into it. no one can figure out what is happening. Now it is happening more and more. we also do not receive updates anymore to the infotainment system. the dealership had to manually do it a year ago. also will not keep our proifile signed in at all. always says were stuck in guest mode. says we have full storage when there is not any apps downloaded.

Vehicle brake module system failed after being replaced one week ago. All of my systems system lights are coming on on my dashboard. I cannot drive past 62 mph. This is the second time that this has happened under a month after vehicle being serviced at a GM dealership.

My vehicle performed an update without my knowledge. When I got back into my vehicle after a quick stop the infotainment system said "Update Failed - Return to Dealer". I did so and was informed that a reprogram was attempted but failed so the entire system needed replaced. There is active recalls I'm told on newer model vehicles with the same issue but mine is not included. So, after the OTA update I didn't ask to take place I'm stuck paying $1,300 for a new infotainment system. I called GM who basically told me without there being a recall there was nothing they could do.

Stopped for gas, then proceeded to leave store, the check engine light came on, and car immediately shut off while on the highway going ~25mph. Car would not turn back on, and then lights for fuel machine error started coming on. Car sat there trying to turn on, lights off, and then would say push start button, but nothing happened. Car began to shake and continued to try to turn on, yet nothing happened. Car was towed to home, sat for an hour and then started again, check engine light remains on.

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.

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.

2 ISSUES - 1) vehicle repaired 5 times for "transmission" problem by replacing wiring harnesses. On 5th attempt, the GM factory part or the technician caused the Tahoe to catch fire. Worst part is that it happened 1 hour after test driving and parking the car at their dealership, thankfully, I would normally have driven it home and it would have destroyed my home too. GM investigated and was unable to determine cause. 2) each time the "transmission" error occurred the GM car went into what they call the "limp" mode. The car immediately loses speed control and drifts to about 35 mph until you have control of the accelerator. I was on an interstate going +70 mph to pass a semi and immediately after passing the car went into Limp Mode, the semi nearly rear ended me and then passed me blowing his horn and cursing me. GM could certainly correct this latter issue by creating a warning on the screen that gives the driver ample time to pull over and address the problem as they do when DEF fluid (this was a diesel) is low and will give warning to add DEF or reduce speed after so many additional miles are driven. The former issue needs to be addressed immediately too, I've noted 4 other drivers on social media that had similar fires. Both of these issues could have resulted in serious injury to me or my family.

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.

The fuel pump power control module failed. We were driving on the interstate going around 75mph with traffic. The car suddenly lost power dropped to 60, 40, 20 in 5 seconds. We barley made if off the hwy`s left side when the Tahoe died. Would not start back up and locked in park. Had to be towed on a flat bed dragged up the bed and brought to the Chevy dealer who confirmed the fuel pump power control module failed and replaced under warranty. We have a 2021 Tahoe, there is a recall for this part but it did not include our vin. Really scary breakdown and could have been hit by another car.

alternator In 2021 Tahoe has went bad twice now! I-??m on my third one. Obviously there is a issue for this needing to be replaced so often.

The truck had an airbag malfunction notice on the information center. We took the truck to the dealer and was told that it was an electrical problem with the airbags. That the only way to have it covered under warranty was for the vehicle to be under the bumper to bumper warranty. The truck at the time the mileage was 39844. We had the truck fixed since it was a safety issue. It cost $420+ to fix it. We feel that it should have been covered due to a safety issue.

We were driving down the road and as I tried to accelerate the car would not go. Then I realized the car said push to start. My husband tried to push the neutral button and told me to restart it but I said you have to push the brake. All this is happening as we are coasting down a main road with speed limits of 55mph and my family is in the vehicle (including 2 toddlers in the back seat). Once we coast to a gravel area off the road I push the brakes and try to restart. My dash goes all black and I try to restart. It tells me battery low push to start. The starter engages and stays engaged until I push the start button again to turn off. The screen tells me it is shutting down functions to save battery. The check engine light is on. We tried 3x with same results. Finally we get out and my parents come to us. Within 15 mins of the initial incident, my husband and dad get in and start my vehicle. My dad suspected the fuel pump. The fuel was right under 1/4 tank but not low enough for the fuel light to be on. They drove to the fuel station, approximately 2 miles away, filled up the tank and drove it to an auto parts store who connected it to a diagnostic machine and it read fuel pump. They drove it back to my home, approximately 2 more miles. The check engine light is still on. I will call the dealership tomorrow. The vehicle has 23,000 miles and is still under manufacturer warranty.
