2022 GMC YUKON Complaints

GM released a special warranty for the coolant control valve. My vin number does not qualify but it is currently at the dealership getting replaced because it failed. I don't understand how the same exact vehicle with a different Vin qualifies but mine does not. I am within the time frame and mileage of their warranty for their special coverage but because my vin isn't on the list I don't get the special coverage/warranty.

In 2023, the vehicle began exhibiting erratic transmission shifting behavior, including harsh and unpredictable shifts while driving. The vehicle was taken to a GMC dealer for diagnosis and repair. Recently, the vehicle developed additional drivetrain and engine control issues related to the crankshaft position sensor circuit. The vehicle stalled while driving on a highway mountain overpass with multiple vehicles traveling behind me. When the stall occurred, the vehicle shifted into park and would not restart for several minutes. This created a hazardous situation due to loss of propulsion in active traffic at highway speed and limited shoulder space. Following diagnosis, the servicing dealer determined that the engine wiring harness requires full replacement due to internal wiring integrity issues affecting critical engine control signals. The crankshaft position sensor and related wiring are essential for engine timing and propulsion. Loss or corruption of this signal can result in reduced engine power, erratic transmission behavior, stalling, or no-start conditions. The earlier erratic shifting behavior appears consistent with conditions described in GM Technical Service Bulletin 21-NA-149, which identifies engine harness-related causes for drivetrain and shifting concerns. This issue appears to involve degradation or defect within the engine wiring harness affecting engine management and transmission operation. Given that this condition resulted in a highway stall and temporary inability to restart, I am reporting this for investigation as a potential safety-related defect involving loss of propulsion.

Driving normally. Stopped at a red light when the car started to touch idle and proceeded to shut off. Tried to restart the car and when ignition button was pressed the screen and all electronics shut off and there was smoke coming from the engine bay. Police were called and the car was towed to the nearest gmc dealer. Was called today 2/10/2026 with the update that it was going to require a new motor.

On Star module quit working in our Yukon, which in turn makes it useless to have any of the safety features. On Star and GM know this is an ongoing problem, but no recall has been issued. Neither company will repair unless an $1100 fee is paid. Why install On Star if you know it will malfunction. Since there is a monthly service fee I think they need to make sure the vehicle has the correct parts.

The contact owns a 2022 GMC Yukon. The contact stated that the vehicle was consuming an excessive amount of oil. The vehicle was taken to the dealer, where it was diagnosed, and metal shavings were found in the engine oil. The dealer replaced the camshaft and lifters; however, the failure worsened. The contact stated while driving approximately 65-70 MPH, the vehicle stalled and lost power steering functionality. The contact's husband was able to pull over to the side of the road. There was no warning light illuminated. The vehicle failed to restart and was towed to the residence. The vehicle was then picked up and diagnosed by the dealer. The dealer determined that the engine had seized and needed to be replaced. The contact had opened a case with the manufacturer for buyback assistance due to safety concerns. The vehicle was not repaired. The failure mileage was approximately 46,000.

Windshield wipers stopped working while driving. Once engine turned off, the wires began working again. Additionally, later in the day while driving home the wipers stopped working again. The wipers have not worked since.

The engine threw a rod on January 23, 2026. The vehicle stranded me on the side of the road. We called the dealership which they came and towed back to the dealership. No dashboard warnings at all. Oil pressure was good. I heard a low tick to begin with then a slight squeaking noise. After the engine locked it was an abrupt halt with the wheels locking up but didn't come to a complete stop. The noise was very loud after that and that's when I pulled off the highway. The dealership checked it out and did find that the motor needed to be replaced. We just had the SUV in the dealership on October 2025 and they found no need for a new motor, just a change in the oil viscosity.

After a dealership repair to the rear differential, my 2022 GMC Yukon XL experienced a sudden driveline failure. A component detached underneath the vehicle, resulting in loss of control and immediate disablement. This occurred shortly after service and without warning. The vehicle is routinely driven at highway speeds while transporting multiple minor children. This appears to be a serious post-repair safety defect.

The contact owns a 2022 GMC Yukon. The contact stated that while the vehicle was parked, there was a dripping sound coming from the vehicle, and the low oil warning light was illuminated. The low oil warning light was illuminated approximately every 1,500 miles after an oil change. After each oil change, the level on the oil dipstick was low. The vehicle was taken to an independent mechanic, where an oil consumption test was performed. The mechanic informed the contact that the vehicle was consuming approximately 25 percent of the engine oil. The vehicle was not repaired, and the contact was referred to a dealer for assistance. The vehicle was not diagnosed or repaired. The contact was informed that an additional oil consumption test was needed. The manufacturer was made aware of the failure and referred the contact to the NHTSA Hotline for assistance. The approximate failure mileage was 87,000.

I am writing to report a failure of the telematics module in our vehicle. The module stopped functioning without any warning or notification on the dashboard. Our vehicle has only 64,000 miles and has never been involved in an accident, so this failure is unexpected. This issue has resulted in the complete loss of OnStar connectivity, meaning that automatic crash notification would not occur in the event of an accident. Additionally, we are no longer able to remotely unlock or access the vehicle through the app, as all communication capabilities are currently disabled.
