2022 GMC YUKON Complaints

L87 Engine failed 6 months after replacement. Had to get 2nd full engine replacement. The car is currently on its 3rd engine. 1st replacement 10/16/25. Engine failed on 4/30/26. 2nd replacement 6/1/26.

We took in our Yukon for the recall letters we’ve received in the mail and to check a suspension light the popped up. Our Yukon was given back to us with the ac not working properly anymore and it started to turn off on us out of nowhere. now we need an engine replacement. What’s more aggravating is that the Yukon was checked out the week of july27 -31 according to service advisor the engine was good and the only thing needing to be replaced was the module for the suspension light that popped up. Now it turns out that it doesn’t even need a module replacement and the suspension issue is something else. Super frustrating It’s our only family vehicle and it so upsetting that we were given the Yukon back in the condition it was in. Thank goodness the Yukon shut off at a drive thru and not a freeway or my husband would’ve got into an accident.

The contact owns a 2022 GMC Yukon. The contact stated that there was an abnormal moaning and grinding sound coming from the vehicle. The contact became aware of the uneven wear on the tires. There were no warning lights illuminated. The vehicle was taken to the local dealer, where it was diagnosed and determined that the differential needed to be replaced. The vehicle was not repaired. The vehicle previously had an alignment and fluid flush performed. The contact stated that the failure was related to TSB: 21-NA-028 – (Rear Differential Moan/Chatter). The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 39,000.

The engine in my 2022 GMC Yukon XL equipped with the 6.2L L87 V8 experienced a sudden loss of power while traveling at interstate speed. The vehicle had previously received the GM L87 engine recall remedy. Despite the recall being completed, the engine failed, leaving me and my family in a dangerous situation. The vehicle is currently at a GMC dealership and is available for inspection upon request. The sudden loss of engine power on a busy interstate created an immediate safety hazard. Traffic was traveling at highway speeds, and the vehicle rapidly lost the ability to maintain speed, increasing the risk of being struck from behind or being involved in a serious collision. My family was in the vehicle at the time, making the incident especially concerning. The GMC dealership has confirmed that the engine failure is related to the L87 engine issue and advised that the repairs will be covered under the applicable warranty/recall-related coverage. Additionally, after the original recall service was performed, an expanded recall was added to my VIN, further indicating that the original remedy may not have fully addressed the underlying defect. The vehicle is currently being inspected by the authorized GMC dealership. Prior to the engine failure, there were no warning signs indicating an imminent catastrophic failure. The recall service had already been completed, leading me to believe the vehicle was safe to operate. The engine nevertheless failed after the recall remedy, raising concerns that the corrective action may not be sufficient to prevent future failures

Vehicle is a 2022 GMC Yukon Denali with the 6.2L L87 V8, covered by NHTSA Recall 25V-274 (GM N252494001). The recall remedy was performed. The engine passed the dealer inspection and was given the higher-viscosity 0W-40 oil remedy rather than an engine replacement. On 05/26/2026, at approximately 43,000 miles, the vehicle suffered a sudden engine knock while being driven by my wife. At the same time, the dash displayed Service ESC and Service Traction Control warnings, the vehicle's speed fluctuated on its own without driver input, and the air suspension cycled up and down while the vehicle was in motion. The vehicle had to be towed to the dealer. The dealer diagnosed a failed lifter with resulting camshaft damage and repaired it under the powertrain warranty. The vehicle was out of service approximately fifteen days. Shortly after the vehicle was returned, it began displaying a "Theft Attempted" message on the dash every day. I reported this to the dealer in writing on 06/15/2026 with a photograph at 43,898 miles. The dealer stated it was unlikely to be related and did not scan or diagnose it. On 07/14/2026, approximately 560 miles after the repair, the vehicle became inoperable and had to be towed to the dealer a second time. It is currently at the dealer and has not yet been diagnosed. The unexpected loss of power, speed fluctuation, and stability-control failure at road speed present a serious crash risk. This vehicle passed the 25V-274 inspection remedy and then experienced a valvetrain failure regardless, which is directly relevant to Recall Query RQ26001 into the adequacy of that remedy.

The contact owns a 2022 Chevrolet Yukon. The contact stated that while driving at an undisclosed speed, an abnormal knocking and ticking sound emanated from the engine before the vehicle stalled. The vehicle was towed to a local dealer, where it was diagnosed with total engine failure, requiring replacement. The vehicle was not yet repaired. The contact stated that the current engine was a replacement engine from a previous failure, which was tested prior to installation but also failed. Additionally, the contact stated after the failure, the transmission could not be shifted into Neutral, forcing the tow operator to drag the vehicle onto the flatbed truck. The manufacturer was not yet notified of the latest failure. The failure mileage was 45,000.

My 2022 GMC Yukon (6.2L L87 V8, VIN [XXX]) is covered by recall 25V-274 / GM N252494000, "L87 Engine Loss of Propulsion." In May 2025, at about 65,800 miles, the engine lost power and shut down while I was driving, then developed a loud knocking noise and an intermittent low-oil-pressure warning. The dealer (The Faricy Boys Automotive, Salida, CO) found excessive metal in the oil sample and replaced the entire engine under this recall in June 2025. The original engine serial was [XXX]; the replacement serial is [XXX]. On XXX, at about 93,000 miles — roughly 27,000 miles after the recall repair — the REPLACEMENT engine GM installed began making the same knocking noise. A dealer (Turner Automotive, Montrose, CO) has confirmed the engine is failing and has ordered a second replacement engine. The recall remedy GM performed did not fix the defect; the engine GM installed to cure the recall is now exhibiting the same failure mode (knocking / loss of propulsion). When the engine failed on XXX, GM Roadside Assistance refused to cover towing despite the engine's replacement coverage, and I had to pay roughly $484 out of pocket to tow the vehicle about 74 miles to the nearest dealer. This is a safety issue: the defect causes loss of motive power, and in my first failure the vehicle shut down while I was driving. I am reporting this because the recall remedy itself appears defective, consistent with NHTSA Recall Query RQ26001 regarding the adequacy of the remedy for campaign 25V-274. Please associate this report with that recall and that investigation. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On [XXX] brake system failure, service ESC, Forward Collision system unavailable and check engine lights came on the dashboard and the vehicle had no brakes. Taken to dealership and Conley GMC advised the Main Module was burnt out. $1200.00. Car was “fixed” and sent out. The next morning all the check engine light along with all other failure lights came on after module was replaced. Taken back to dealership and they advised that everything had to be manually programmed which was done and sent out. [XXX] same dashboard errors were up again. Taken back to dealership and they advised they needed to reprogram manually that was done and sent out. The next morning all lights were back on. It was the weekend so they wouldn’t take the car or provide a rental. May 23rd car was taken back to dealership and Conley advised the master cylinder was bad and had to order parts. $4300.00 in repair cost along with 2.5 week at the dealership and $150.00 in rental cost. I found online that GM knew of this issue with the 2022 GMC Yukon XL vehicles and a recall was made however this vehicle VIN number was not included in this recall. I notified Conley GMC and they stated they were not informed of this issue. I made a claim with GM and told them of this issue and my safety concerns and they advised that because this was not included in the recall that there was nothing they could do and they would not be covering financial assistance or reimbursement and they called this an inconvenience instead of a real safety issue as each time my vehicle had no working brakes. No working brakes causes safety concerns for everyone in the vehicle as well as other vehicles. All work orders are at Conley Buick GMC in Bradenton, Fl.

the full audio system went out on the vehicle at 40,000 - the amp and safety warnings that come through the car audio failed and took 2 days to replace at my expense for the amp to have the features active
