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)

With no warning, my engine 6.2 L stopped running at highway speeds and failed to restart. The power train completely failed for a second time after having a previous engine replaced for the same failure in 2024. I had the car inspected per the recall along with changes in the oil viscosity as recommended along with service inspection. The car left me stranded again on rural highway for over 5 hours in temps that exceeded 98 degrees. The car would not start and went into a power save shutdown and had to be towed to the dealer. I was fortunate to have avoided any traffic on the highway enough to get the car off the road. This is not safe to drive on the highway and GMC has known defect and safety concern with this issue.

The engine began making a metallic knocking noise while at idle and very soon after began to make the same noise under acceleration. This noise sounded very much like the onset of rod bearing failure. The vehicle was driven straight home and parked. We called the dealership the next day and made a service appointment. As I drove the vehicle to the dealership, the engine noise became worse and was clattering very loudly as I pulled into the dealership parking lot. I pulled into a parking spot and let the engine idle with the transmission in Park while I was collecting some personal items when the engine stalled. I tried several times to start the engine but it would not crank. The dealership engine tech later confirmed that the engine was seized

The engine had a sudden loss of propulsion on the highway traveling at 70mph. It went into netural and I had to coast to the side. Power cycled and it started back up for 15 more miles, then did it again and would not go out of park. Towed to dealer. PICO L87 recall was completed prior to purchasing the vehicle. 300 miles after purchase, the engine locked up. Dealer confirmed its an L87 recall failure. Vehicle was inspected on 4/21/2026. I have been waiting on a motor for 7 weeks with no movement.

During normal driving conditions the vehicle had set code P18A1 in the ECM. Code set due to an internal short in one of the solenoids in the valve body assembly. This caused the vehicle to display "Limp Mode" and lose reverse gear and propulsion over 45 mph. The vehicle was parked and towed to the dealership for evaluation. Upon inspection by a certified dealer technician, it was found that a solenoid had failed and required replacing. As part of the entire valve body, the solenoid is not a serviceable part. The dealership had to replaced the entire valve body assembly per repair guidelines. Per the GM and NHTSA websites, my 2022 GMC Yukon XLT with a 10-speed transmission is not included in the recalls listed below even though the symptoms are identical. General Motors publicly acknowledged the 10‑speed transmission valve body and solenoid defects, including internal electrical and hydraulic failures, through Safety Recalls, Special Coverage programs, and Technical Service Bulletins applicable to 2020– 2022 full‑size trucks and SUVs, including the GMC Yukon. My vehicle’s model year, transmission type, failure code (P18A1), and repair align with those documented GM conditions and should be included in this recall.

Experiencing a stuck lifter in the DFM module. After doing some research, it appears there are a bunch of other people that are dealing with the same issue. The only recall was for the 6.2L engine but not the 5.3L. It appears that both engines are experiencing the exact same issue and GM hasn’t done anything to help with it.

We were driving on 95S when the Yukon Denali automatically shifted itself from D to N. On the dash it had a warning message to press start again. When my husband did that we could smell a smoke smell. Meanwhile, we are in the middle lane of the highway while trying to safely get off the middle of the interstate without being rear ended by the semi that was behind us. We finally made it to the side of the interstate where my husband was able to put the Yukon in park. He was never able to get the vehicle back in Drive. The car would never click back over to start up again. We had to have the vehicle towed to the nearest GMC dealership where it has now been for almost 3 weeks with no timeline for a date of a new engine. I was told it needed a new engine and radiator. Said the alternator was trying to catch fire when he was trying to start the vehicle. This is the SECOND time the Yukon has been in the dealership in 4 months for this recall issue. This time it is 2hrs away from my home.

Good afternoon, I am submitting this complaint to report a serious and potentially life-threatening safety issue involving my 2022 GMC Yukon Denali. While traveling northbound on State Road 417 (toll road) in Florida, approaching Exit 45, I was driving approximately 75 mph when, without any warning, the vehicle suddenly shifted itself into neutral. A message immediately appeared on the dashboard instructing me to press the start button, and the vehicle rapidly lost power and began to decelerate in the middle lane of a high-speed highway. This sudden loss of power created an extremely dangerous situation that could have easily resulted in a major collision. Vehicles behind me were traveling at highway speeds, and I had no ability to safely maintain speed or predict the failure. The lack of warning makes this issue especially concerning, as there was no opportunity to take preventive action. After the incident, I contacted OnStar for assistance. The vehicle was towed to Carl Black GMC, where the service advisor confirmed that the engine requires a full replacement. A complete engine failure occurring suddenly at highway speeds, without warning, is not just a mechanical issue—it is a critical safety hazard. This type of failure puts not only the driver but also passengers and surrounding motorists at serious risk of injury or death. It is deeply concerning that a vehicle of this age and caliber would experience such a catastrophic failure. Issues like this must be addressed immediately, as they have the potential to cause severe accidents if they continue to occur without warning. I strongly urge that this matter be investigated thoroughly and that appropriate action be taken to ensure that other drivers are not placed in similar dangerous situations. I was fortunate that my children were not in the vehicle at the time of this incident. The outcome could have been far worse. Please let me know if additional information is required.

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.

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.

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.
