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.
Electrical system, Nov 27, 2024
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.
Electrical system, Engine, Jun 10, 2024
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.
Power train, Electrical system, Vehicle speed control, Apr 23, 2024, fire
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.
Electrical system, Air bags, Other or unspecified, Jan 20, 2024, crash
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.

Electrical system, Air bags, Nov 21, 2023
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.

While driving at night, the vehicle instrument cluster suddenly blacked out. All driver information pertaining to speed, fuel, tachometer, oil pressure and convenience lighting failed. The entire instrument cluster was an unlit black hole. I called GM and they advised there was no reports of this issue and no recalls pertaining to my specific vehicle number. A quick on line Google search revealed service bulletin [XXX].The GM associate I spoke with said they could not confirm or deny that other complaints of this problem had been brought to their attention. She stated that all parts in all their vehicles are vin number specific and that it’s possible I’m an isolated incident. I feel GM Is aware of this dangerous issue and should immediately issue a safety recall before the effected vehicles are involved in fatal crashes after being startled by this blackout event. This is clearly a driver safety issue that GM is not being proactive addressing.

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.

The dashboard for the vehicle loses all power and does not regain power/connectivity. I've had this problem "fixed" 5 times by the Chevy dealership and the issues continues. They've replaced the entire dash, checked electrical components, changed out the electrical bank, and the issues continues. Driving down the road at 65 mph to have your dash go out is not only terrifying but extremely dangerous! I have no idea how fast I'm going, how much gas I have, no situational awareness related to vehicles that are close by... the ENTIRE dash goes out. This is a brand new 2021 Chevy Tahoe... I bought it with 4 miles on it and within a month of the purchase, the vehicle had this problem.

The vehicle was manufactured with a push button transmission gear selector. If there is an electrical issue(ie. dead battery, electrical short, engine failure, etc) you cannot shift transmission gears. If I pull into my garage, notice a burning smell coming from engine area, possibly an electrical short, I cannot put vehicle in neutral to push out of garage in case it does erupt into a fire and not burn down my house. Recently my dead battery caused the tow company to lift the back end and pull it our of garage. General Motors did not install an override to put transmission in neutral in an emergency. The transmission will only shift if the engine is running. Imagine driving on a road or stopped at a traffic light and the engine stalls, will not restart, good Samaritans offer to push you off the road, but can't shift to neutral. Dealerships have a hydraulic lift they place under rear tires to move vehicle around service area. As a retired law enforcement officer, many times we had to move vehicles out of the way until wrecker serviced arrived. I feel this is definitely something that has to be addressed and corrected before major damage occurs or lives are endangered.

Traction control and forward collision warning lights stared to go crazy in August 2021 (3800 miles), five months after buying my Tahoe. Sales rep indicated his new 2021 Silverado did the same and he was able to get it to reset by turning off and restating his engine. So I did the same and thought my issue may have resolved itself. Yesterday, the warning lights started to go haywire again (6700 miles) This time my vehicle felt as though it was going to stall and was making a clicking noise under the hood. The warning lights continue to flash regardless of how many times I turn on and off the engine. The engine also revs loudly.
