2022 Gmc Yukon

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)

the sensor on the left side of the vehicle fails to detect as it should. A warning indicator comes on the screen when you start the vehcile

The rear shocks in my GMC Yukon AT4 failed and began leaking and had to be replaced. This supposed to be an off-road durable suspension and the shocks are failing?

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

with no warning ,the GMC 6.2L engine failed on my family trip to Colorado. The engine seized at HWY speeds, stopped running, failed to restart and had to be towed to local dealer. This issue is a known GMC defect with numerous reports and a safety recall issue. I was fortunate to be able to move offer in hwy traffic and get to the shoulder where my situation took 8 hours travel time to continue my family trip.

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.

OnStar telemetry module failed. Needs replaced. These modules are on back order. Safety features and emergency calling are disabled due to failed telemetry modules. Over the air updates cannot be completed due to the failure of the telemetry system. Important module updates from the manufacturer are not happening.

The contact owns a 2022 GMC Yukon. The contact stated that while driving at various speeds, the vehicle suddenly entered LIMP mode, the speed was reduced, and the vehicle failed to exceed 55 MPH. The Check Engine warning light illuminated. The vehicle was taken to the local dealer, who diagnosed that an emission system failure had occurred, but the cause of the failure was not determined. The vehicle was not yet repaired. The manufacturer was notified of the failure. The failure mileage was 11,000.

OnStar module failure. No communication with vehicle in the event of emergencies. Safety systems disabled. No remote access to unlock/ lock doors. No remote start. No speed limit notification. All built in apps and wi-fi no longer functioning.

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.

Vehicle has 58,800 miles on it driving down highway started smoking and motor making a clanking noise.

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.

The contact owns a 2022 GMC Yukon. The contact stated that while driving at an undisclosed speed, the vehicle lost automotive power. The hazard lights, collision, road traction, and check engine warning lights were illuminated. The vehicle was taken to a dealer, where it was diagnosed and determined that the cam lobe and cylinder #6 lifter had failed, and the lifter and camshaft needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 82,000.

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.

The telematics module aka OnStar, doesn’t not work.

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.
