CHEVROLET Complaints

Failure of Battery Energy Control Module (BECM), within the high voltage battery. Vehicle is unable to charge and sets “reduced power” message. GM released special coverage bulletin for this issue (N232432680), but this vehicle is not listed due to which state it was registered. Continued failure of the BECM will lead to inoperability of the vehicle.

At purchase, I noticed that the brakes felt spongy and were screeching when the salesmen pulled up. The salesmen stated that new brakes always screech due to burned plastic. Weeks later, I scheduled a servicing appointment with Chevy Crews in North Charleston, due to brake screeching, the repairmen told me again that the brakes had condensation on them, so he dusted them off and the screeching would stop in 3 weeks. 3 weeks later I returned again, the salesmen told me that GMC made the vehicles with faulty brakes. My vehicle was seen over 4 times for screeching brakes, thousands of consumers have complained about the same issue, and GMC has failed to act.

Transmission problems 124,994 miles . It's the same defects as the 2019-2025 defects.

Front automatic emergency braking has activated abruptly three times in routine following traffic while I was already braking behind a slowing vehicle. It caused a very hard stop and nearly led to a rear-end collision from the vehicle behind me. Please inspect the forward camera/sensors, calibration, AEB settings, and check for any related fault codes or software issues.” This happened on 3/18 while I was getting ready to go onto the freeway and the cars in front of me slowed down I applied the brakes to slow down and the ABS brakes abruptly and strongly I was almost rear ended. There was another passenger that felt the same thing and commented on what happened.

My 2022 Chevrolet Tahoe has a recurring pattern of excessive oil consumption, smoke from the exhaust, repeated check engine light events, P0420 catalyst-efficiency faults, and repeated catalytic-converter-related repairs. At approximately 75,000 miles, the vehicle shut down on the freeway. At approximately 121,000 miles, the first catalytic converter failed. Chevrolet of Wesley Chapel documented P0420 and catalyst failure in November 2025, and GM service history reflects catalytic-converter replacements at 131,468 miles and approximately 141,082 miles. The vehicle also underwent major injector-related repair in early 2026. At 141,620 miles, Chevrolet of Wesley Chapel started an oil consumption test and stated in writing that oil consumption can lead to repeat failed converters and false oxygen sensor readings. Despite substantial repairs, the problem pattern continued. I am reporting this as a possible safety-related defect affecting engine operation, emissions-system failure, and drivability, and I am asking NHTSA to review whether this indicates a broader safety-related defect.

The vehicle has 2 permanent codes. One is a communication blackout, the other code means the hardware is melting. GM is doing a formal inspection in April. The Ucode meant that the engine stopped talking to the transmission or visa versa. The vehicle “ran my daughter and I” off the highway into the dirt, on 2 different occasions. They are described as “catastrophic engine failures”. The last one occurred on MLK Jr Day 2026, before the vehicle was permanently grounded. It could have been fatal. GM is doing a formal investigation to see what liability the have for it because the vehicle is now considered a “lemon”. There were no external (dashboard) warnings before the events, but, there may have been internal ones that require a professional grade scanner to detect. The permanent Ucode, which causes a communication blackout, never appeared in the vehicles memory, on a scanner, until AFTER the local GM franchise conducted “repairs” (unsuccessfully) to fix the vehicle. (It wouldnt start, which is often a symptom of a Permanent UCode. The GM investigation will determine if the dealership knew the safety liability, (the permanent Ucode) and they tried bypassing or ignoring it, or, if they CAUSED the safety defect. Also, the vehicle is now showing a Permanent PCode, which means it is now a potential fire hazard.
