2020 Chevrolet Tahoe Electrical Problems

Your StabiliTrak system has turned off about 5 times over two months at very low speeds (under 5 mph), with the warning light and beep appearing in most incidents. When this happens, you lose power steering and brake power, which is a serious safety concern. The dealer says they can't diagnose the problem unless the warning light is currently on. The fix will likely involve diagnosing the StabiliTrak system's electrical connections and sensors, possibly replacing faulty components or updating the vehicle's software.

Your car is locking you out by automatically locking the doors even when you're still nearby, and it's not reliably detecting your key fob from a distance—you need to have the fob physically close to the car for it to work. Additionally, when someone opens a door while the engine is running in park and then closes it, your car beeps as if the remote is no longer detected. This happens with both of your fobs even after replacing their batteries, suggesting an electrical issue with the car's keyless entry system rather than the fobs themselves. The fix will likely involve diagnosing and repairing the vehicle's remote keyless entry module or antenna.

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.
