2022 GMC YUKON XL Electrical System Problems

OnStar Module is disabled, this is a key safety feature, one of the reasons I purchased this vehicle.

the digital gauge cluster suddenly black out and do not show any information such as speed, rpm, signal, etc at all. this is very serious issue for driver and passenger safety.

The driver-side headlight and turn signal on my 2022 GMC Yukon stopped functioning completely. This issue began before GM recall 22V‑903 and worsened immediately after the recall repair was performed. The recall repair required three separate dealership visits because it was initially performed improperly, yet the problem was never fully resolved. During interactions with GM and the dealership, I was told the repair might involve a $600 part, but they could not guarantee that replacing it would fix the issue. It is unreasonable and unsafe for me to be expected to cover the cost of repairs for a problem that was caused or worsened by a recall repair performed incorrectly. The malfunction creates a serious safety hazard, as oncoming drivers cannot see my turn signals, and I nearly had an accident because of it. The problem has been confirmed by the dealership and documented in GM Case #74327012. Prior to complete failure, the driver-side turn signal and daytime running lights occasionally stayed on after shutting off the vehicle which I was told that was caused by the recall. The vehicle has been inspected by authorized GM dealerships multiple times, but the defect persists. The component is available for inspection upon request.

The engine system (6.2L V8 L87) in my 2022 GMC Yukon XL failed due to a known manufacturer defect tied to NHTSA Campaign 25V-274. The vehicle is available for inspection upon request. The issue involves the risk of sudden loss of propulsion, which could result in a crash or injury to myself or others. This is a serious safety concern, and I do not feel safe operating the vehicle in its current condition. The defect has been acknowledged by GMC, but there is no remedy or repair currently available. I have contacted the selling dealership (Rick Hendrick Buick GMC, Duluth, GA) repeatedly for the past three weeks with no returned calls. I also contacted GMC corporate, who confirmed the recall but refused a buyback or replacement because no repair has occurred — even though a fix does not exist. They offered a loyalty voucher that does not come close to addressing the safety risk or impact. The problem has not yet been inspected by a dealer or manufacturer because there is no repair action to take at this time. No police, insurance, or third-party has reviewed the vehicle. There were no warning lights or messages prior to the issue — the problem was revealed when I looked up the VIN and learned of the active recall on the engine. I am requesting NHTSA’s support to ensure General Motors provides a replacement vehicle and compensation for this ongoing and unresolved safety hazard. I should not be placed in a position where I am expected to continue operating a vehicle with a known and dangerous defect that has no resolution in place.

OnStar telematics module

I jumped in and turned the car on and started driving. Right away I noticed most of the warning lights were on. The first speed bump in the complex made me realize I had lost 80-90% of my brakes as if I had a broken brake line for example and steering was a little hard and pulling a bit to one side. I check underneath I did not have any leaks. I decided to take it to the Dealer to have it checked. Dealer said they were not able to find anything and cleared the codes. dash lights on: check engine lane depart drive assist ABS BRAKE

Reported electrical issues beginning one month after purchasing the vehicle. I reported issues for the first year including the running boards not working, entertainment system not operating, hard engine restart/stalling and the reverse camera not engaging. February 2024 the car was driving down the highway and a loud noise began in the engine. Entire car stopped running. Placed in the shop for 29 days to replace the engine, battery, computer, and other items. The next day engine began to stall again. Monday at 10am the car stalled again and was unable to be turned back on. Car was then taken for another 15 days fuel injectors, spark plugs and other items changed. Again received the car back and had issues with stalling and engine revving issues. Turned into dealership and bought another GMC Yukon. GMC refused to admit an issue and refused to help.They only changed out the initial engine and paid for the rental. Car under full warranty for manufacturer plus maintained my extended warranty. Reported to BBB.

Filmed the engine noises and high idle on 06/22/23, engine light came on and returned to service department at 37,265 miles. Engine was replaced after a lengthy wait time for replacement. Cam and Lifters were the issue in original engine. Received vehicle back 08/30/23. MODULES: Reported the display changing 1/30/23 with 26,608 miles, service documents state related to telematics controls. They replaced the module. Vehicle had a delay in shifting, reported on 06/06/23 with 36, 303 miles. Transmission control module was out of calibration and was reprogrammed at a dealership service department. Vehicle shifted into neutral multiple times. Reported to service department 09/08/23 at 38,183 miles. The transfer case lost communication with the brake control module, but they started communicating again without repairs according the service invoice. Then there was a recall for the screen switching displays, which it has done the entire ownership, even after replacing the module. Turned into dealership for that recall, it was updated, the displays still change screens while the vehicle is in use.

Engine Failure (Engine Seizure) (Connecting Rod bearing Failure). Enige Failed on an interstate highway causing us to nearly be struck by traffic moving at a high rate of speed. Also, Engine failed on an extremely cold (-17) degree Minnesota Night. This cause extreme concern/anxiety with children in the car as we waited for recovery. Yes, the problem has been confirmed by a GMC dealership in Hudson WI. Yes, the vehicle component has been inspected by both GMC certified technicians as well as 3rd party warranty technicians. Zero warning lamps or messages prior to the failure.

On [XXX] my vehicle displayed an engine light on the dash. The light went on and off randomly throughout the day. The vehicle was hooked up to a computer that said there were no issues and everything was fine. On [XXX] I drove the vehicle over 240 miles to Pittsburgh and back with no lights. At one point the vehicle did make a loud noise for the drive but I took it out of cruise control and everything was fine. On [XXX] while driving to Poconos, PA with my family (husband, self, children ages [XXX] , [XXX] , [XXX] and [XXX] ) on [XXX} at approximately mile marker [XXX] the vehicle's engine quit working. The engine light came on and we were able to coast off of a bridge and onto the shoulder of the highway. We were unable to exit the vehicle due to high rates of speed of oncoming traffic and the shoulder not having much room. We contacted OnStar who sent a state trooper to assist with traffic control until a tow could get to our area. The vehicle was towed to Blaise Alexander in Bloomsburg, PA. My and my three youngest children had to ride with the state police officer and my husband and older son rode with the tow truck due to not having anything to fit a family of 6. The police officer told me that he had a 2024 GMC Yukon Denali have the same issue in the same spot on the highway a week ago. The vehicle has just over 25,054 miles on it. On 3/10/25 Blaise Alexander called to state that there was metal in the engine and the engine would need to be replaced. The service manager stated that they have had a few GMC Yukon Denali vehicles with this issue and that the engines may be on back-order. I have also had issues with radio presets resetting, audio not working with turn signals, navigation, radio and phone and alignment since I owned it for the last [XXX] days. From my research, this is a known problem with GM engines for the engines in the 2022 GMC Yukon Denali. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving on the highway the engine just shut off with no warning or other indication of problem. The dashboard computer instructed to restart the vehicle, which it would not restart. Managed to get to the side of the road. But the vehicle was unresponsive. After about an hour the lights in the rear of the vehicle flickered, so I attempted to re-start -which it did, and was able to drive the vehicle to the dealer (about 20 miles away). Where the car remains today. The incident occurred Feb 2. Took the dealer until 2/6 to advise me that the engine would need to be replaced. At that time they indicated they would need to car for about 2 weeks. I contacted them on 3/3 and they informed me they had no idea when they might be able to get the parts to replace the engine - there was a 3,000 engine backlog? Clearly there is a major issues with these engines; how are they allowed to continue to sell these vehicles, and allow current owners to operate them without a notice? While I was fortunately able to get to the side of the road - have in the car lose power suddenly lose power is clearly a safety issue!

In July of 2023, my wife and kids were driving to San Diego from Phoenix. About 40 miles west of El Centro, CA, all the lights on the dash came on instructing her to pull over. When she pulled over and shut the car off, it would not come back on. Got towed back to a GM Dealership in El Centro. The diagnosed it with a bad radiator and failed engine. The replaced both(at roughly 30,000 miles). The car was fine for about six months and then it started getting battery drains again, which continually happened starting a few months after purchasing the vehicle. They never could figure this part out. Anyway, early January of 2025, while driving back to Phoenix from San Diego, the car did the same thing. This time, it restarted and she could continue on her way home. On [XXX], while driving in town, the same thing happened, all lights came on, pulled over and car would not restart. It is diagnosed with the same issue. It has been in the shop at Van GMC since January 12th, 2025 waiting on a new engine, at 63,000 miles. This will be the 3rd engine in the vehicle. By looking online, this appears to be a common issue and happens more than it should. This needs to be addressed. My wife has our kids in this vehicle a majority of the time and this is a major safety issue. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Traveling North bound on Highway 14 in Southern California on January 24, 2025. In the fast lane traveling approximately 70MPH when with no warning what so ever the vehicle shifted into neutral and lost power. Nearly rear ended trying to get out of traffic and to the right shoulder. Once stopped the vehicle would not start, stuck in Park, and could not turn the electronics off. Stuck in vehicle for 3 hours because it was too dangerous to exit vehicle. Tow truck arrived. Tried to jump the battery which by this time was dead. Had to drag the vehicle up the flatbed with wench do to vehicle unable to shift out of Park.

I am writing the NHTSA to advise of a harrowing event involving the vehicle named above. I was driving my 2022 Yukon vehicle equipped with the 6.2L Ecotec3 V8 L87 Engine. As I was traveling, the vehicle suddenly without warning shut down. When this occurred all systems in the vehicle became completely inoperable; i.e., no power steering, no power brakes, nothing, Etc. I was lucky to be able to veer/coast into the Emergency Lane without incident. This situation also caused the vehicle to become almost un-towable, in that the towing company could not get the vehicle out of the Park position to allow the wheels to rotate. They had to use special Skid Plates / devices to essentially force the vehicle to Slide instead of rolling onto the towing vehicle. This added significate hazard and risk of injury because of the problematic situation of loading the vehicle in this manner literally inches from the active travel lanes and took much longer to load than it would have otherwise. The vehicle was towed to the local dealer. The Dealer replaced the Fuel Module and returned the vehicle. This information is being sent to GM as well. After this event I was concerned for driving the vehicle but now after reading about the recent NHTSA Investigation into Engine Failures I am much more apprehensive about driving the vehicle. Even if nothing happens individuals who have these vehicles have now lost significant value and face a very difficult time even being able to sell their vehicles at all, or at a much lower price than normal because of the known Defects. I hope this helps the NHTSA to further their Investigation of GM’s defective vehicles and get these vehicles repaired and/or replaced in a timely manner before tragedy strikes any individuals.

As we were leaving Cortez, CO. on a two lane highway we were passing a couple of cars with plenty of room to get back into to the driving lane when we lost ALL power from the engine. The cars we had just passed had to slam on their brakes as we were trying to keep from a head on collision. But with no power and the Denali in neutral we couldn’t change anything. We coasted to a County Road approach and it DIED in the middle of it. NO POWER. We had to call a tow truck who took it back into Cortez to Webb Chevrolet. The engine had seized. God was watching over us that day. We have since found out that there has been MANY seized engines with the 2022, 6.2 liter engines. In many new pickups and few of the suburbans. In fact, the Webb Chevrolet people said they have had one that they replaced the seized engine with a new 6.2 liter engine and in 500 miles that NEW ENGINE ALSO SEIZED! This is a MAJOR SAFTEY ISSUE!! THIS ENGINE NEEDS TO BE RECALLED BEFORE IT RUINS LIVES OF THE FAMILIES WHO ARE DRIVING THEM!!. We only had 42,000 miles on our 2022 Yukon Denali and Chevrolet couldn’t even rent a vehicle to get home and it would be a month to have to wait for a new one. We had to trade vehicles to get home. Point is, when the engine seizes while passing cars on a two lane, somebody is going to die. Families aren’t at fault when the company has been notified of their negligence to get a recall on this engine and fixed. We’ve had our Denali in for service several times for electrical issues. This should qualify as a Lemon Law. Instead, GMC tried to send a $5000.00 voucher to use when we buy a new vehicle. This family has bought GMC, CADILAC’S, CHEVY’S FOR OVER 50 years. We like our salesman and would continue this business, but not if you don’t make SAFETY FIRST!! RECALL THIS ENGINE NOW!!! Take care of YOUR customers and OUR friends! LOOK FOR YOURSELF THE AMOUNT OF SEIZED ENGINES IN THIS 6.2LITER ENGINE. Thank You, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA)
