Repeated issues with the infotainment system had to be replaced 3 times to date. The motor blew at 49,000 miles 3 weeks ago. The replacement motor is on back order and it is very difficult to get a loaner vehicle, not to mention having to make a payment on the vehicle that I don’t have to use.

Info center with radio, vehicle info, on star keeps going black screen. When this happens I loose all control of info center and on star goes out where no location would be available if the vehicle was in an accident. This is safety concern because with no automatic notifications of accident no one would know if vehicle was in an accident. The vehicle has been to dealer 4 times for this problem since February of this year. Each time the dealer says it needs another update each time. Gm is having this issue with many of the vehicles like this Tahoe. On star is also aware of the issue too. Gm knows there's an issue but now they are saying I have to pay for an update because I am out of my extended warranty even though this has been an ongoing problem which started when I was in warranty. This has to be a programming issue that they need to fix. The vehicle has to be shut off for up to an hour for screen and controls to come back on which is safety issue because no way to change any settings for vehicle and safety backup because of no on star.

Vehicle has been doing this since February 2024 but dealer would state the recall would fix the issue. February 18 2025 vehicle claimed to have a dead battery. Took to dealer once it was jumped they kept till February 28,2025 when I picked up vehicle less than 5 mile down the road vehicle shut off and luckily I was at a red light and the vehicle behind was not following close. The vehicle had just left dealership. Once I was able to get the vehicle back on it stated I needed to service the transmission. Took vehicle back to dealership and then they kept it to check. March 4,2025 I was told to pick up vehicle I did and it seemed well drove 6 miles to destination. Parked it and went inside came back out an hour later and vehicle was dead again. Had to call tow truck to pick me up and they left vehicle at dealer and it has been there since and they are stating it is in line.

Key fob does not work even when inside vehicle or either cup holders. I was able to use auto start a few times but having both keys inside or using one or the other spare or primary causes the no key fob message. The only thing that has worked has been to open hood, disconnect primary battery terminal and wait ten minutes. Afterwards, everything seems to be working. I refuse to believe that a brand new vehicle has to be operated in such a manner. I’m a nurse who works 15 hours a day and all I wanted was to go home to my family but now I’m stuck at work waiting for my husband to come disconnect my Tahoes battery for ten mins before it hopefully works again.

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.

Traveling on the interstate late at night in the winter with my family, which includes small children, a clicking noise began but then went away. No diagnostic lamps came on, everything seemed fine, vehicle responded appropriately. Moments later, on a remote stretch of interstate, we lost power and the engine shut down. The vehicle would not turn back on. We were stranded in the dark on a freezing night.

While driving, without warning my brake system failed and vehicle did not stop when I applied my foot on the breaks. In addition to while driving up a steep incline the engine failed as I was actively applying my foot to the gas pedal causing vehicle to roll backwards. Most importantly I do not feel confident using this vehicle any further knowing that the brakes are not operating as they should, risking my life and my children’s life is nonnegotiable. Someone help please.

On one morning w/20 something temperature, Tahoe started and immediately shut down. When restarted, multiple malfunction lights were lit: engine, abs/brake, steering column, traction control, etc. Reached onstar for advice to see if Tahoe was drive-able, but only got confirmation of system malfunctions and offered roadside assistance but declined since at home and would call back if needed. About an hour later and several restarts, all malfunction lights finally cleared except engine light, which stayed on for another day or so. Tahoe drove okay during engine light on.

After start up, there is no audio coming from the vehicle. No audio from entertainment system, no audio from turn signal and no audio from fasten seat belt "chime". Restarting vehicle does not change the outcomes, initially. Exiting the vehicle and restarting about 10 minutes later, all audio returns, including entertainment sytem, audible turn signal indicator and fasten seat belt chime (if seat belt is not engaged). This has occured on several occasions since about 11/1/2024.

Continuous alert(3 months)- service transmission, unable to shift gears. Safety concerns due to possibility of transmission failure.

Driving down the freeway at 75 mph and the headlight started flickering any time I would use my blinker. 5 minutes later the car automatically breaks hard all by itself along with the dash lights going off and the doors locking and unlocking. 3 days later driving in town taking a hard left suddenly I get alerts on the dashboard saying, "parking assist off" and "stabilitrak" then suddenly my steering wheel jerks violently all the way to the right. This happened 2x when I am driving!!! it is available for inspection upon request. If this steering wheel malfunction happens to someone driving down an interstate someone could die. It just happened yesterday so I have not gotten it in to be looked at yet. There was zero warning it all happens suddenly and out of nowhere.

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.

Onstar telematics module failure. Part is on backorder with no eta. This module failure removes the navigation, onstar services including safety notifications, clocks can stop working, android auto/apple carplay services are not functional or intermittently working. My vehicle has stalled out at a red light. Gm is refusing to cover the replacement saying it is out of the bumper to bumper to warranty but they have so many of these needing replaced they can't say when they will get the parts. Module has been confirmed dead by a mechanic at a private shop and by the dealership. Gm states this is under the bumper to bumper to warranty even though it controls parts of the power train and should be covered under powertrain warranty as well.

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.

P2138 code causing the car to have reduced engine power causing unsafe driving conditions and danger to other traffic. Vehicle has been to dealer multiple times for issue, ecm replaced costing thousands and still not working.

The contact owns a 2023 Chevrolet Tahoe. The contact stated that soon after purchasing the vehicle, the vehicle's lane assist feature would be active with no other vehicles in the contact vehicle's vicinity. The contact also stated that multiple other electrical defects would occur such as the backup camera activating while in drive(d), the instrument panel intermittently going blank, and various other defects. The vehicle was taken to the dealer on multiple occasions where they failed to duplicate the failure. The contact then stated that while driving at 80 mph, the instrument panel went blank. The contact attempted to pull the vehicle over; however, an unknown turn-off of the vehicle warning message appeared on the instrument panel as a warning chime was also emitted from the vehicle. The contact then stated that the vehicle then came to an abrupt stop where the engine and brakes seized, while traveling at 34 mph. Due to the failure, the contact was taken to the hospital where they were treated for whiplash, inflammation in the neck and spine, 7 bulging discs in the spine, and pain in various parts of the body. The vehicle was towed to a dealer where it was diagnosed with engine failure; the vehicle's engine was replaced under warranty. Despite the repair, the contact refused to take possession of the vehicle as they did not feel safe driving the vehicle. The manufacturer was notified of the failure and a case was filed; the contact had yet to receive any assistance from the manufacturer. The failure mileage was approximately 15,000.

Trailer brake warning message, making car un drive able.

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.

Purchased brand new. Had for awhile and the veh shook. Took it in and the replaced with all brand new lifters. Still not correct than replaced with all new fuel injectors. Now when I take it in for the last several months it’s 1. 5 to 2 quarts low on oil. Told that gm standard says 1. 5 quarts low between oil changes is normal!!! I’m currently on an oil consumption test at each 1,000 miles snd I’m at 2 qrts with 1,500 til my next oil change. The volume on the radio goes up and the computer is stuck and you cannot turn the radio off or use the computer screen at all. You have to turn off the vehicle and start it again in order for the buttons to work.

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.

Keeps saying service trailer brake system and does not stop ringing in the dashboard it’s very distracting while driving .

I writing to complain about the "trailer brake" warning light that suddenly appeared on my 2020 Chevrolet Tahoe. After visiting the internet I then saw other complaints about the module on the dash for the trailer brake adjustment having repeated complaints. I have never used the 2020 chevy Tahoe to tow a trailer that had its own braking system. The only thing I have towed was a small u-haul trailer. All the complaints about this module is the same: warning light on the dash display. If so many other chevy Tahoe owners have complained . . . What hasn't there been a recall for this repeated electrical malfunction?.

While driving on the highway at high speed, my vehicle suddenly shut down and went into neutral. After a few minutes of trying to start it, it started and I was able to drive it home. The following day, on my way to the dealership for an inspection, while driving on a busy street, it shut down again. This time, it wouldn't restart, and I had to call the police and a tow truck to have it towed to the dealership. I was freaking out as I had my daughter inside the car with me. At that point, the vehicle had around 26,000 miles. The dealership inspected it and determined the engine was faulty and needed to be replaced. After the engine was replaced, the vehicle seemed fine, but recently, I've been experiencing problems again. The car struggles to start when it shuts off during stops, using the auto shut-off feature, and there's an intermittent hard shifting issue. It feels like the engine is failing again or maybe the transmission, but I've been told that unless the dealership can replicate the issue when I bring it in, they can't do anything. I'm concerned about being stranded on the road again, especially since my daughter is always with me. The vehicle’s engine and mechanical components don’t seem reliable, and I no longer feel safe driving it. However, I have no other option as it is my daily car for work and everything else. I’ve asked for an extended warranty from the dealership after the engine replacement, but I was told GMC doesn’t offer one for this issue. I’ve seen others on social media report similar problems, and I want to share my experience, as I’m just one of many customers facing this issue.

Several months back I took my car in to my local dealer for a recall and asked them about what was going in with my navigation and radio because when I'm driving the navigation system will deter from my destination that I put in and then start flipping through radio stations on its own and will not let me change or control it at all.
