2022 GMC Yukon

While driving on the interstate at highway speed, the vehicle suddenly lost acceleration and stalled. I was forced to pull over. After stopping, the vehicle displayed a message to restart, but it would not start. All electronic accessories (lights, dash, etc.) remained functional, but the vehicle would not shift into drive or neutral. The message “Conditions Not Correct for Shift” appeared. Nearly rear ended, this created a dangerous situation due to loss of power in active traffic and inability to move the vehicle on a 250,000 vehicle per day very busy tollway.

My transmission control valve failed while I was driving causing my speed to reduce on a high speed high. I know longer could go in reverse, about 35mph or above 2nd gear. This is a known issue on the 10 speed transmission for 2022 Chevrolet Tahoe, Suburban, GMC Yukon however my vin number was not included in the recall but it happened to me. This was a terrifying situation and i am so shocked as to why my vehicle was not included in the recall to begin with.

While driving my 2022 GMC Yukon with approximately 150,000 miles, the engine suddenly began running rough and I immediately pulled over. The vehicle had to be towed to the dealership. The dealer diagnosed a collapsed lifter and camshaft damage and recommended full engine replacement at a cost of about $9,450. The vehicle had no prior engine issues and most miles are highway miles. Sudden engine failure while driving creates a potential safety hazard due to loss of power. I am reporting this because I understand there are ongoing investigations into GM V8 engine failures and I believe this failure may be related.

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.

There was an engine recall on the vehicle that was inspected and passed. My wife noticed the vehicle shaking while she was driving and the engine mounts ended up being broken. They replaced the engine mounts and they had it up on the lift when they reported that engine failed. They replaced the motor and gave the vehicle back to us. About 2 weeks later my wife noticed a grinding. She took it in and they said the differential needed to be flushed. That would be at our cost. Then they did that and it did not fix the issue. So they determined it was the rear differential that needed to be replaced. We got the car back after another 2 weeks and it was fine for about 2 weeks. My wife noticed another grinding and we turned it in before the warranty expired and now they have to replace the rear struts. All in all over the last 6 months the car has been in the shop for at least 2 months getting repairs because of major catastrophic failures in their components.

My 2022 GMC Yukon with the 6.2L V8 engine is covered under recall 25V274000 for connecting rod and crankshaft defects that can cause engine failure. Approximately three months ago, Wiesner GMC dealership performed the recall inspection and stated the vehicle passed. Recently, the engine suddenly began misfiring on cylinder 6. The failure was sudden and severe—the vehicle started shaking significantly, the check engine light illuminated, and multiple safety sensors began deactivating. The vehicle was clearly unsafe to drive. An independent repair shop diagnosed oil leaking into the cylinder and stated the condition is consistent with internal engine component failure—the same type of defect the recall is meant to address. When I contacted the dealership to have it re-evaluated, they stated my vehicle is no longer under standard warranty and I would be responsible for repairs. After escalating to GM customer service, they confirmed extended coverage exists under Special Coverage N252494003 (10 years/150,000 miles) if the diagnostic confirms the issue is related to the recall defect. The fact that my vehicle passed the recall inspection three months ago and is now exhibiting the exact failure symptoms the recall was designed to prevent raises concerns that the inspection procedure may not be detecting all affected engines. The component (engine) is available for inspection. This defect poses a serious safety risk as the sudden loss of power and deactivation of safety systems could cause a crash.

The contact owns a 2022 GMC Yukon. The contact stated that the turn signals audible sound failed to operate as designed. Additionally, while reversing into a parking spot, the vehicle turned off while going over a bump. The message "Park" was displayed after restarting the vehicle. The contact stated that while driving 25 MPH over a bumpy road surface, the vehicle turned off and the brakes became inoperable. The vehicle was coasted to the side of the roadway. Upon restarting the vehicle, the message "Service Transmission" was displayed, and the turn signal sound became operable. The contact was able to drive to the residence. The manufacturer was notified of the failure and agreed to tow the vehicle to a dealer to be diagnosed. The vehicle was not yet diagnosed or repaired. The failure mileage was approximately 25,000.

Dropped my 2022 Yukon Denali off May 7, 2025 to Mike Reed Chevy due to failed transmission. Order was placed May 15, 2025 for a valve body part. Multiple phone calls were made without success on status of repair. I was forced to drive to the dealership for answers on June 10. I was told that due to my car being under warranty I am at the mercy of GM. The Part needed is apparently on indefinite backorder. Contacted GM to expedite part and was told it could be 3+ months before I can expect my car back. Claim number with GM is 55328239. After doing research, there is over 2000 people who are experiencing the same issue. Mike Reed Chevy nor GM offered assistance with a rental to offset the inconvenience. It was only until I demanded to speak with the service manager that I was given a rental car. As someone who manages a hospital, the delay in obtaining this part has caused significant hardship, and to date, there has been no clear timeframe provided for when the part will become available or when repairs can be completed. As a consumer, I am left without reliable transportation as the dealership has requested me to return my rental. The lack of transparency or timeline for resolution is deeply concerning. This has not only impacted my ability to fulfill daily responsibilities, but has also raised broader concerns about the availability of necessary vehicle parts and the protections in place for consumers in similar situations. I am seeing guidance or intervention from your office to help expedite this matter, whether through direct communication with the manufacturer, identifying legal remedies available under consumer protection laws, or advocating on behalf of consumers facing unreasonable delays in vehicle repairs due to supply chain issues. Any assistance or direction your office can provide would be greatly appreciated.

Total valve body failure in the transmission at 30k miles. I was traveling with my daughter on the freeway at 65 mph and the vehicle went into limp mode. No indication of problems prior to this incident. Vehicle has been at dealer going on a month now. They have no valve bodies available, on a national backorder. They replace it with the valve body that is known to fail again. GM knows about this problem and the solution they offered was only a software upgrade so the back tires don't lock up when this happens. My daughter and I could have been seriously hurt or killed.
