2022 GMC Yukon Xl

I think it is a transmission type of failure. I'm not sure of the exact mechanical specifics. While putting the vehicle in reverse, driving and or accelerating it feels like the transmission is locking up and then releasing, and then locking up again. It felt very dangerous for that to happen while driving down the road. I took the vehicle to a local mechanic that was near by for assistance and he said I should take it to a dealership because there was a recall due to that issue on my type of vehicle that he knew about. So I call a dealership to make an appointment, tell them I think the issue is due to a safety recall due to the transmission locking up. They check my Vin# and say there are no recalls for my vehicle, even though it falls in the same year, make, and model of affected GM vehicles , therefore they could not make a recall appointment for me. Even though i was experiencing the same type of issues on the same type of vehicle thats included in the recall. I did not have any warning lights before, or while driving. The day it happened, I drove the vehicle to work, parked, was at my office all day. Came out to go home and put the SUV in reverse and it like lunged forward, almost hitting the car parked in front of me. I thought I must have had it in the wrong gear or something. So I put it in park and then tried again. Then it felt like it locked up, rocked forward, and then allowed me to back up. I put it in drive and again it was like it was locking up and releasing very forcefully but then smoothed out and drove normal for a few miles and then locked up again. There were never any warning lights or messages during this time. I called GM to inquire why my vehicle isnt in the safety recall and all they could tell me was that they did not know. I was very afraid I was going to be involved in an accident due to this issue.

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

My 2022 GMC Yukon XL with the 6.2L L87 engine was previously subject to NHTSA Recall 25V-274 / GM Recall N252494000 for L87 engine loss of propulsion. The recall was closed by the dealer as “PicoScope Inspection — Engine Passed / Update Engine Oil Type,” with the oil/cap/filter remedy. The vehicle was later brought back to the dealer for engine noise/knocking, check-engine light, and engine oil light/oil warning concerns. The dealer has now confirmed that the dipstick was not picking up oil, the oil level was severely low, the oil condition was severely degraded, and abnormal engine noise was heard. My VIN also shows active GM Special Coverage N252494003 through 1/15/2032 or 150,027 miles. The dealer previously stated that the underlying PicoScope pass data from the recall inspection is no longer available to the dealership after submission. This is not the first oil-related concern. During a prior service visit in September 2025, around the same time the L87 recall was completed, the dealer documented an engine oil low message and an upper oil pan leak causing the low-oil message. I am concerned the L87 engine may be failing after the recall remedy was previously marked complete, creating a risk of engine failure or loss of propulsion while driving. I am also concerned the current engine/oil/noise condition is being treated as customer-pay/out-of-warranty before the root cause is fully diagnosed or reviewed by GM under Special Coverage N252494003.

Engine failure occurred while driving with two children in the vehicle, creating a serious safety hazard. The vehicle experienced a sudden loss of power and stalled completely while in motion, with no prior warning lights, alerts, or messages. Prior to this failure, the vehicle had already failed the GM PICO test related to the known L87 engine issue, and the recommended corrective action was changing the oil to 0W-40 synthetic and replacing the oil cap. Despite that intervention, the engine still failed at approximately 49,000 miles. A sudden complete engine stall without warning while driving created a dangerous situation, particularly with children in the vehicle. This raises concern that the prior corrective action did not resolve the underlying defect..

While driving in traffic on a 2 lane road with small shoulders, the engine stopped, dash indicated automatic shift to neutral, restart vehicle. vehicle coasted to a stop partially blocking the lane due to lack of shoulder and size of vehicle. Turned off ignition and attempted to restart. there was a click and the dashboard/electronics all went blank/off for several seconds then came back on. Attempted this 4 times with the same results. Called GMC roadside assistance for a tow to the dealership. The vehicle could not be shifted to neutral due to not being able to start. The tow driver had to forcefully pull the vehicle onto the flatbed with the vehicle still in park. I do not know what method was used to get the vehicle off the flatbed tow truck. Vehicle was partially blocking the roadway for an hour before the tow truck arrived leaving me vulnerable to a high speed crash. And leaving the tow operator open to an accident during the 30 minute loading Upon diagnostic the dealer informed me the engine has seized/locked up. All recalls for loss of propulsion were completed at 48,711 miles on September 7, 2025 passing inspection and dealer performing an oil change to 0W40 oil. Engine failure was 3429 miles after the recall was performed with 52,140 miles. There was no warning or difference in driving characteristics prior to failure. There was not a loss of oil pressure prior to failure according to dash gauges.

On 8/22/25 was brought to my local GMC dealer for the L87 engine propulsion recall. The dealership tested and said the vehicle passed the test. On 12/3/25 while driving on a multi lane highway the vehicle engine stopped abruptly. The message restart engine appeared on the dashboard. I had to negotiate other vehicle travelling at highway speeds to get to coast off to a side street. The transmission went into "park" and could not be shifted to neutral with a message on the dashboard "transmission cannot be shifted in this configuration". I was blocking the roadway and responding police asked that I attempt to restart the vehicle. I did this numerous times but would not start and the battery ran down. The vehicle was towed to the GMC dealer who said the battery failed and replaced it at my cost even after I told them it was fine and run down from trying to start numerous times while blocking traffic. On 12/17/25 while trying on the same highway, the engine abruptly shut off again in high speed traffic with the same message. I couldn't get fully in the shoulder dye to residual snow from plowing coasting powerless as the vehicle slowed. The transmission locked into park again and I ended up getting towed back to the GMC dealership. They advised me the engine seized up and would have to be replaced. I am still waiting to get the vehicle back

I am writing to formally express my dissatisfaction with the vehicle I purchased from your dealership. Despite my expectations at the time of purchase, the vehicle has not met the standards that were represented to me. This letter is intended to address my concerns regarding the vehicle’s features, undisclosed recalls, and significant mechanical and safety issues discovered immediately after delivery. I discovered—through the GMC mobile application, not through the dealership—that the vehicle had two to three active recalls at the time I received it, including recalls involving the engine and transmission. I was never informed of these recalls by the dealership prior to or at the time of sale, which is extremely concerning. After discovering the recalls myself, I scheduled a service appointment. I was informed that the recalls were addressed and marked as resolved in GMC Springdale. Despite the recalls being cleared, only two days later, the vehicle began experiencing issues. The screen displayed warning messages, and the vehicle developed a vibration, to the point that it became unsafe to drive. They are changing us $820+tax I was forced to use roadside assistance, it hasn't been a month yet and the dealer are refusing to cover the damage. I have been calling but they said they are busy or they use somebody else to speak.

While driving northbound on I2 at approximately 70mph I experienced a sudden loss of engine power. Vehicle would not accelerate and engine ultimately powered off. I was able to move across three lanes of traffic and pull over on the side of the highway. I attempted to restart the vehicle but was unsuccessful and after about 10 minutes the engine managed to start. The ‘check engine’ light was on after the incident and upon arriving back home I ran a code scan that resulted in code P129F indicates a problem with the fuel pump control module. There is recall #N252516900 dated 9/11/2025 which covers this issue for 2021 models only. This occurred on a 2023 model.
