general problems of the 2020 Chevrolet Tahoe

Suddenly lost all power steering, then warning power steering attention, no control for steering, very dangerous, couldn't drive vehicle. Took independent car repair to fix. $5k repair to fix problem. Should not happen to vehicle.

On multiple occasions, my car has locked my keys on the inside of the vehicle. I have put things inside my vehicle before leaving and closed all the doors, upon returning, even just a few minutes later, my doors are locked and I am locked out of my vehicle. Additionally, my car is not detecting my remote. I cannot unlock my car with the buttons on the door and need to have my keys in hand for my car to detect the fob. Additionally, if someone opens the door while the car is running but in park, and then closes the door, the car will beep as if there is no longer a remote detected. This has happened on multiple occasions. I have changed the batteries in the fobs multiple times, switched out my fobs so I was using a different fob and it has happened with both of my fobs.

My 2020 Tahoe stabilitrak has gone off approximately 5 times over the past 2 months April and may of 2025 in one incident my vehicle did turn off all incidents were at low speeds less than 5 mph. Four of the incidents the stabilitrak light turned on and an audible beep, I also lost power to my steering and breaks. When I had the oil change the service tec at the dealer stated they can not test it unless the light was on? has anyone reported or experiences this issues what can be done to fix this issue. Please email me at [xxx] if you have any questions or helpful hints. Thanks [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Trailer brake system warning comes on an alarms tones begin. Distracted driving situation and faulting wiring issue. Has occurred on multiple occassions in addition to this time.

Trailer brake warning message, making car un drive able.

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?.

Rear view camera goes off starts with striped blurry lines then goes to blue screen says “service rear vision system”. Took to dealer battery tests low. They recommend replacing battery, positive and negative cables to the tune of $1000. They aren’t positive this will fix it they say this is what they start with there are several errors codes with that system message. Not covered under extended warranty because they say it’s wear and tear/maintenance. Haven’t had issues with the battery just the rear view camera system. 2020 Tahoe LS 3 yeas old. Battery shouldn’t be bad this soon. Chevrolet needs to recall this rear camera system.

Back up camera does not work. Quick google search shows this is a common issue in gm vehicles with no real identifiable fix. Starts with blurred lines and within weeks it turns to just a blue screen. Backup camera is a safety feature and therefore should be investigated by NHTSA.

Auxiliary battery exploded while vehicle was in operation. Explosion caused damage to front driver side headlight, hood insulation, windshield washer reservoir, terminal covers and battery. See attached images. Later learned of gm service bulletin (19-na-099) regarding overheating of relay causing melted terminals on auxiliary battery.

Stopped at a traffic light my power steering warning light on the dash came on. After that I had no power steering, and the vehicle is very difficult to steer. I drove back to my location turn the vehicle off and who won out about an hour later started and the power steering was working. Upon looking the issue up online I found that other models of my Tahoe have had a recall but no particular model has not.
