2022 GMC Yukon Powertrain & Transmission Problems

Monday, March 30, 2026 my GMC Yukon Denali had already had the recall pico test and was told it passed on September 2025 six months later March 30, 2026, driving to pick up my wife from work a tapping sound coming from the engine started and about a mile down the road from when I first heard the tapping the engine started juttering and the noise got louder like a clunking sound. I had to pull off the road into a gas station and use the OnStar to get assistance the vehicle was towed to a local San Antonio dealership Cavender Buick West they gave me a loaner vehicle the next morning and the day after that Wednesday I was informed that yes they confirmed the engine will have to get replaced so now I am waiting for that. I was told by the dealer it could take up to two months for them to receive a replacement engine and once they receive the engine, it can take roughly for maybe five days for turnaround. I inquired whether the replacement engine isn’t upgraded engine or is it the same engine that has all the problems I haven’t received an answer for that yet. I am awaiting that answer from my service advisor. He said he is looking into that.

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.

I took this vehicle in for the recall that GM had indicated. The vehicle was taken to a GMC dealer and “passed” the PICO test and the oil was changed out as recommended. Two weeks ago, the engine completely seized while driving in the interstate and was towed back to the dealership. I am now waiting on engine replacement after passing their solution. The car has roughly 30,000 miles on it.

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.

Original inspection and recall was performed on my 6.2 engine on 12/02/25 and the engine failed on 1/15/26 , the vehicle is in the shop awaiting new Engine

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.

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.

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.

Driving on the highway the engine suddenly revved high and suddenly went into limp mode on the highway. Reverse is no longer operational. 2022 GMC Yukon with 49,000 miles. Limped the vehicle to the dealership who has indicated it needs a new transmission valve body that is currently on national backorder given the prevalence of the issue. I have been requesting a work order denoting the failure and required repair but have not yet received from my dealership. I will pass this along as soon as I receive it. I spoke with GM customer service last night requesting their assistance in getting this for me.

Vehicle has no reverse. 21,750 miles and have been told by the dealer that it needs a transmission valve body which are unavailable at this time and it could be several months before they are able to obtain the valve body.

My vehicle radiator fan immediately cut on high when I turned on the vehicle. The temperature of the vehicle was normal. I also experienced this when the engine was completely cold. I was assured there was no need to tow the vehicle but I could drive and schedule service with dealer. The software triggered a reduced acceleration condition. This did not allow me to accelerate as needed while navigating an interstate interchange.

Sudden loss of power while driving approximately 60 MPH. Dash saying "press engine start". The vehicle lost all functions while moving at about 60 mph with zero warning signs. After diagnosis with the GMC dealer, crank bearing failure led to complete motor loss. The concern was there was no warning signs, noises etc. that would allow to get the vehicle to a safe location off the road. We were lucky we were going straight and not on a corner and able to coast to a wide enough location to get the vehicle off the main lanes of traffic.

I was driving on an expressway in Chicago heading to work at 5am on [XXX] morning. While driving my engine shutdown and I lost engine power to my vehicle while doing 70mph. There was no warning, no warning lamps and no noise to indicate there was any issues. The vehicle just died while I was driving. I had to coast to the shoulder with traffic all around me. Luckily I was able to avoid other vehicles and they were able to avoid me when they realized I was having trouble. Though there was a very close call where I almost got into an accident. When I pulled onto the shoulder the vehicle completely shutdown. It would not restart. I had to call a tow company to have my vehicle towed to the Dealership. Luckily, I was able to find one nearby that was open at that time on Christmas Eve. The dealership mechanics went over my vehicle and determined that I had complete engine failure. The bearings on the bottom end of the engine spun out. I now need a complete engine replacement along with whatever other components were also damage. This incident was a major safety issue. I was luckily that I did not end up in a major accident due to the loss of complete engine power. This is a major issue that needs to be looked into and GM needs to be held responsible for not only my vehicle but all others that this is happening to.

The engine started making a rattling sound. Brought it to the dealer and they told me the engine is bad and it needs a new one. They told me this issue with lifters and the fuel management system is a common problem leading to internal metal components breaking. My car has been with the dealer since 12/30/24 and I was told this week from the dealer the problem is so big there aren’t any engines available and they have no idea when I’m getting it back. When I initially dropped it off, they said approximately a month. Now they are saying they don’t have a clue.

Engine failure as a result of a bearing failure. I have been waiting since December 3, 2024 for a replacement engine.

My transmission began having problems the day it was delivered to me. After the oil change which they delivered to me at low percentage was completed the motor was ticking. It has had a burning smell and has been in and out of the shop and going back soon. I was on the expressway and the speed declined with error messages on the dash almost resulting in an accident. No one is listening to my concerns and now the motor has a metal clinking noise
