The engine needs replaced and GM doesn't have any engines or know when we will get any engines. Evidently this affects numerous 6.2 liter engines that GM made from 2021-2024.

I was driving my Yukon with my family back from a trip and my Yukon engine shut off while on the highway. The vehicle went into neutral but I was driving down a hill when is all happened. Luckily there wasn’t much traffic and I was able to pull of to the side of the road. There was no check engine light or indication of any issues prior to this incident happening. After this incident, the vehicle turned back on and was able to drive home. Now it is seating at a dealership waiting for a new engine with no eta on a new engine.

Driving on the highway the engine suddenly revved high and suddenly went into limp mode on the highway. Reverse is no longer operational. 2022 GMC Yukon with 49,000 miles. Limped the vehicle to the dealership who has indicated it needs a new transmission valve body that is currently on national backorder given the prevalence of the issue. I have been requesting a work order denoting the failure and required repair but have not yet received from my dealership. I will pass this along as soon as I receive it. I spoke with GM customer service last night requesting their assistance in getting this for me.

ENGINE
While approaching a red light, my 2022 GMC yukon just shut off leaving us unable to start it or even shift it to neutral to move the vehicle. This posed danger with oncoming traffic, so my family and I got out of the vehicle while awaiting a tow. We had to get the car towed and it was determined to have complete engine failure due to a rod bearing issue. One hour prior to it failing we had a check engine light come on. No other noises or warnings prior. The car is now at the dealership awaiting a new motor since still being under warranty. The motors are on backorder so its unclear how long this will take.

ENGINE
Without any signs of an issue the engine seized while driving on the highway, Thursday [XXX]. Thankfully my wife was exiting the highway when the vehicle shifted its transmission into neutral, allowing my wife to coast onto the shoulder. The vehicle would turn on the electronics, however the engine would not attempt to turn over. The vehicle was towed to Carl Black GMC of Kennesaw. I was originally told the transmission was the potential problem but the transmission tech was on vacation until the following Monday the 14th. Once they looked at the vehicle, at that time they determined that it was not the transmission. The engine had seized and that there is at least a 6 month wait for another engine. They have not recommend a further diagnoses of the exact failure within the engine due to the common occurring issue with these engines.

The evening of Tuesday [XXX] driving from College Station, TX to Pasadena TX my GMC 2023 GMC Yukon starting making a clicking noise but no warning lights. For about an hour the noise persisted louder and softer and the check engine light would flash 3 times then stop, for a while then flash again. I did notice that when applying gas I didn't get the normal increase in acceleration but I couldn't tell if it was a power issue or a transmission issue. I was traveling about 60mph on a freeway thankfully in the right lane the vehicle suddenly shut off with no warning. I had no power, brakes did work and I could steer and I was able to make it to the area between the main lanes of the freeway and the lane of an onramp. Once stopped I attempted to restart the vehicle and nothing happened. We were stuck. Onstar was contacted and a tow to a dealership was arranged. A sheriff deputy stationed his vehicle behind us to provide protection until the tow truck arrived. The vehicle is now at a GCM dealer and I have been told the engine has locked up and needs a complete replacement. I have no other information in those regards. There is a long back order for new engines and the estimate is at 4 weeks. I did see the check engine light flash 3 times and then go off for a while then start again, but we were no where close to home and it was somewhat late at night. I also had coworkers in the vehicle taking them back to our office. At this point this is as much as I know but thankfully i was already in the right lane or this might have been a much more difficult situation.

POWER TRAIN, ENGINE
While driving on the mass pike with my fiancé and 4 kids our motor suddenly died. We were using cruise control going 75mph and the vehicle shifted into neutral itself and the car died. I managed to make it to a break down lane and we had to sit there for 2.5 hours before a tow showed up to help. The dealership said the motor seized and we were under the 60K for warranty and it was covered. They got us a rental the next day and then on the 3rd day they called and said it was lack of oil changes that caused it and they asked if i had records of service history. We bought the vehicle used and only had the vehicle long enough to perform 1 oil change. We did our oil change on time and I'm trying to locate service records from the dealership we bought it from. However there were no signs of dark and contaminated oil when i did the oil change at my shop and also no sounds or warnings coming from the vehicle prior to the motor seizing up. I think they are trying to get out of paying for the motor when its clearly a known problem with these 6.2l engines.

ENGINE, ELECTRICAL SYSTEM, POWER TRAIN
Approximately 14’000 miles we were told a rod went through the engine. Our vehicle failed at a high rate of speed leaving myself, wife, and 2 young children to pull off a major highway and call for police to help slow traffic. This happened while driving 70 mph on the highway. The only warning we received was when the car went from “D” drive to “N” neutral on the highway. Fortunately, we had enough time to pull to the side of the road before complete engine failure. GMC road side was not helpful. We were told we would have to find a ride home over an hour away, and when our ride arrived, so did the tow truck. Then, they had to drag the vehicle onto the flatbed because the tow truck company did not have the unlocking device for the wheels. Upon getting it to our house, the tow truck company had to rock our vehicle off the bed! We were not able to tow it where we purchased it. We either had to tow it to the nearest GM dealer or our house. We chose our house because the nearest GM dealer from where we broke down would've been over an hour away from our house. Our second engine failed 2200 miles later while my wife was sitting at a light in a busy intersection. The car again went from “D” to “N,” and it was immovable. The cops had to be called because the tow company couldn’t come fast enough. We were towed out of the intersection, but I waited over 5 hours with several dropped tows for a tow company. That occurred on my birthday. We are now on our third engine, and GMC wouldn’t warranty the engine. Our brand new tires went at 32,000 miles because GMC could not confirm or deny that rocking our vehicle on and off the flatbed three times didn’t affect the alignment. The front two tires inside tread was worn. I was told the tires from the factory are 50+ thousand mile tires. We barely got 32,000 miles. We’ve had multiple issues with electronics, back up camera, and media package. The Lemon Law won’t cover us because our first engine did not fail before 12,000 miles.

[XXX] [XXX] [XXX] April 17th, 2025 Spearfish Cadillac Attn: [Service Manager or General Manager] North Main Spearfish, SD 57783 Subject: Engine Failure and Safety Concerns – 2023 GMC Denali Ultimate (6.2L V8) Before ordering my 2023 GMC Denali Ultimate (MSRP $96,000), I raised concerns about online reports of engine problems with the 6.2L V8. I was assured by your staff that there were no known issues with this engine and that I had nothing to worry about. However, within the first year of ownership, I began reading verified reports about widespread engine failures involving this same 6.2L engine across various GM models. I contacted your dealership again and was told that my vehicle’s VIN did not indicate any problem or need for replacement. Since that time, I have experienced two severe engine failures, both at highway speeds of approximately 80 mph. Each failure caused my vehicle to abruptly shut down and lurch into a different lane of traffic—creating traumatic and extremely dangerous situations for both myself and surrounding drivers. In addition, I encountered another instance in which the engine would not start. A stranger helped me jump-start the vehicle on two separate occasions. Believing the issue could be battery-related, I replaced the battery (which was less than three years old), only to suspect later that the engine may have partially locked up. I am formally requesting the following: A written response confirming whether a replacement engine has been or will be installed in my vehicle, and if so, whether it is a new build, remanufactured, or an identical L87 engine model. Confirmation of whether any updated parts or engineering revisions were made to resolve known lifter or bearing issues.

I've taken my 2021 Yukon Denali to GMC dealers complaining of "clacking" noise coming from the passenger side of the engine on 3 occasions. Each time, they tell me that they do not hear anything. Now, I see that the L87 engine has defective bearings which could lead to abrupt engine failure which could lead to a dangerous situation. I envision power sliding on the highway going 70 mph and ultimately rolling over and getting killed. I am now frightened to travel on the highway and see no resolution forthcoming from GM. They are just looking at $. My wife and I are [XXX] and travel to Florida from Wisconsin every year for winter. The Yukon to me was the most expensive, ni est vehicle that I have ever owned, but now feel like I could die anytime while driving it. Who would want to buy it now with this cloud over it, all hinging on how GM handles this mess. I've only owned GM products my whole life, but would never buy another now. Lost faith, and hopefully won't die waiting for GM to do something. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was sitting at a stop light and my vehicle completely failed without any warning. Was not able to start, etc. it was completely dead. There was no notice of issues or problems; no messages, no lights, etc. The vehicle had to be towed to a dealer and has been sitting for over 5 weeks waiting for a new motor. I was told that there is no timeline for when a new motor will be available and that it could be months! I travel with my vehicle for work so it is really needed!

Engine shut off twice driving down the highway at 70 mph. Electronics completely shut down then started back up, engine shifted to neutral and wouldn't let me shift out of it. Pulled over to shoulder and restarted engine. Took to Ewing GMC and no issue was found, vehicle was returned. A week later, exact same thing, but this time engine would not restart. Had to be towed to dealership. Engine is blown and have been waiting on a replacement for 3 weeks currently. This is an extremely dangerous issue, people will die from this if it is not corrected. Even once I get the vehicle back, I'm concerned about my family's safety while driving it.
