Purchase this Vehicle November 1st 2025 as a GM certified used vehicle. Had several issues with the camera system including the backup camera. Would go offline and not be usable for days. Vehicle went back to shop several times for this with no resolution. Now February 18th 2026 at approximately 630PM EST (after sunset) on the way into work traveling on the highway the engine lost power and engine shutdown. Vehicle shifted into neutral with the indication to press the start button in order to shift into Drive. This cause all of the lights to shutdown when it tried to start the engine. I was barely able to pull this over to the shoulder before I lost forward motion. Narrow shoulder. Tried to restart again with the same results. Call towing company. They attempted to jump start vehicle. Same results. All power shutdown. Truck was loaded onto flatbed and towed to dealership. Dealership states bad battery. Got authorization to replace battery from the dealer in which I purchased the truck. hey attempted to start and then it burned out the main fuse. They determined that the engine had seized and they were going to replace the engine. I looked up to find that GM had performed the engine oil replacement procedure in June of 2025. This vehicle is listed in the "recall" for defective L87 engines. Clearly changing the oil had no effect to remedy the issue. I have no faith that the new engine will not fail the same way this one did.

Our 2021 GMC Yukon XL with the 6.2L engine suffered a catastrophic failure requiring the engine to be replaced. The diagnosis was very similar to the GMC 6.2L engines that have been recalled for safety and failure reasons however our vehicle was not included in the recall. The engine only had 75,924 miles and was maintained to the manufacturer's maintenance schedule. The cost to replace the engine was $11,309.87.

ENGINE
Without any warning, the V8 L87 6.2 liter engine suddenly seized up, began shaking with significant reduced power. I was fortunate that I could drive slowly to safety and was not on the expressway. In my research, I understand this is related to a design/manufacturing issue with the connecting rods and crankshafts in this type of engine. As I investigated the issue, I found that 600,000 vehicles were recalled with the recall either completely replacing the engine or upgrading the oil type from standard to a thicker, higher-viscosity 0W-40 full synthetic to provide better protection under high stress, along with a new oil cap and filter. In our case, we were directed to change the oil and even with that change, we experienced this dangerous engine failure which cost us $12K ! For that cost of repair, we elected to have the engine replaced for about $1K more to get a 100K mile warranty on the engine. However, our additional concern with the replacement engine is they gave us a remanufactured version of the L87 and we have not found confirmation that they have adequately addressed the design/manufacturing flaws so may be vulnerable to the same seizing issue. We appreciate your attention to this widespread GM issue.

My 2023 GMC Yukon Denali is currently at the dealership due to a manufacturer recall involving the engine. The engine issue occurred while I was driving with my children in the vehicle, which required me to pull over and have the vehicle towed to the dealership After inspection, I was told the vehicle requires a full engine replacement. The dealership has stated there is no estimated time of arrival for the replacement engine due to backorder, and that other customers have been waiting for extended periods. I am currently without my vehicle and have been provided a temporary replacement that is not comparable. The extended delay and lack of timeline are causing significant loss of use.

ENGINE
Engine failure with the 6.2 engine. My engine failed the Pico test in July of 2025 with 66k miles. The entire engine was replaced and I was told this would “fix” the engine issue. On April 25, 2026, my engine failed while I was driving at highway speeds. The engine was knocking and I pulled over as I could not accelerate it. I had it towed and was told by the dealership that the rod bearings failed and I would need an entire new engine. 9 months and 10k miles after a brand new engine was installed. This will be the third engine in this vehicle since I’ve owned it. GM’s “fix” for the 6.2 recall is not a fix. It’s pushing the problem down the road, risking lives by putting people in vehicles with known engine failures and no true fix.

On 3/14/26, on I-75 in Troy, Michigan at 70mph the vehicle, with 4000k miles on the odometer completely shut off. I pushed to restart the engine and it would not restart. My whole family was in the car and we were on a curve. I was able to coast to a flat shoulder. The vehicle would not restart or shift out of park. OnStar took seven hours to tow the vehicle. The dealer is installing a new L87 6.2L engine. I do not have the vehicle back yet. I received an economy car as a loaner. The dealer says GM will not extend the factory warranty despite the engine replacement. My family could have been easily killed.

I ordered and purchased this vehicle in November of 2021. Since it was new, it has consumed approximately one quart of oil per oil change interval as indicated on the oil life monitor system. Every time I have it serviced by the same dealership, I have inquired as to if this amount of consumption is "normal". They said it wasn't excessive yet to continue monitoring it. This vehicle did pass the recent engine recall inspection yet I'm still feeling as if there may be a problem that hasn't fully surfaced yet based on the initial recall.

On April 20th, 2025 while accelerating from a stop light, my vehicle (2021 GMC Yukon Denali XL, 6.2L V8) started making a ticking noise and the service engine light started flashing. I was within a few minutes of my house and limped my vehicle home. The next morning, I started it and it exhibited the same symptoms. I called my local GMC Dealer, Wright Buick GMC, and was advised to have the vehicle towed to them. It was towed to the dealership and within a few days I was advised that the engine needed replaced. I had heard a story that there was a pending recall, so I had hoped that this would resolve itself without a bill to me. unfortunately I was advised that there was no actual outcome on how to handle recalls, so if I wanted my vehicle back, I would have to pay the $11K for replacement as I was outside of my power train warranty (I had roughly 73,000 miles on my car). I have hoped for some resolution to include my vehicle in this recall but I have not yet received any word from GMC.

On [XXX], my 2022 GMC Yukon Denali XL (VIN [XXX] ) experienced a complete loss of propulsion while I was driving on [XXX] in El Paso, Texas, with my wife and two young children in the vehicle. Mileage was approximately 50,364. While in motion, the vehicle was displaying abnormal behavior, concerned the vehicle would stall on the highway, I exited at the Geronimo exit. As the vehicle slowed, it shut down entirely. Multiple restart attempts failed. The dashboard cycled on and off, displaying a "Service 4WD" warning while the vehicle was in 2WD mode. The transmission locked, and the vehicle became inoperable in the middle of the roadway with traffic passing on both sides. OnStar SOS was activated to communicate the unsafe location. The El Paso Police Department was requested to divert traffic. A city tow vehicle arrived after approximately fifteen minutes; my family was assisted across the roadway. Roadside assistance did not arrive for approximately three hours. This was the second loss-of-propulsion event on this vehicle in less than twelve months. The first occurred in March 2025 and resulted in engine replacement under NHTSA Safety Recall 25V274 (L87 Engine Loss of Propulsion). The [XXX] failure occurred after the recall remedy had been applied and the engine was replaced. The vehicle was towed to the dealer who replaced the throttle body, intake air duct and a service item titled "Repair open ground circuit". I am filing this report to document a second loss-of-propulsion event on a vehicle that already received the remedy under Recall 25V274, and to ensure NHTSA has visibility into the potential pattern of recurring or inadequate remedy on the L87 platform.

The current 6.2L engine recall was completed by Janssen Chevrolet in Holdrege, NE and it was noted the vehicle was fine. On April 11th, while driving down Interstate 80 in Nebraska, the engine suddenly died and would not restart. No warning lights or indicators illuminated prior to the failure and there were no symptoms. By sheer luck, it occurred before the head to head construction area with no shoulder and there was a rest area within coasting distance that and we were able to reach. I had little children in the car and we were stranded on the highway until friends were able to pick up the family and transport them to Lincoln and I was able to travel with the tow truck to deposit the vehicle at Husker Auto Group in Lincoln, NE. I was forced to rent a vehicle from a 3rd party as the dealer was closed and it was Saturday evening. On Monday, the dealer confirmed metal in the oil and filter and that the engine was completely dead and unable to be repaired, requiring replacement under the current recall. A much smaller loaner vehicle, insufficient to transport my family has been provided. It has been 13 days and there is no update on how long the vehicle will be out of service awaiting an engine.

VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I was on the Highway and had the vehicle on cruise control, the super cruise was not available the entire trip. Suddenly a warning came on saying that supper cruise was not available please take the wheel, the truck started slowing down drastically while I’m doing 70mph which is the speed limit. I put my foot on the brake to disengage the cruise control but that did not work. I had to push the cancel button on the wheel to take it off. This has happened to me twice while on the highway.

POWER TRAIN, ENGINE
I am submitting a complaint regarding a serious engine failure in my 2022 GMC Yukon XL equipped with the 5.3L engine (VIN: [XXX] ). The vehicle has experienced a complete failure of the lifters and camshaft. Prior to the failure, there were noticeable engine performance issues, including abnormal ticking noises, rough operation, and loss of power. The condition worsened rapidly, ultimately resulting in the engine becoming inoperable. This failure presents a significant safety concern, as the sudden loss of engine performance or power could occur while driving at speed, increasing the risk of a crash. The vehicle is currently not drivable and requires extensive engine repair or replacement. Given the severity of this issue and the potential safety risks, I am requesting that this complaint be formally investigated. I understand that similar issues have been reported in vehicles with this engine, and I believe this may indicate a broader defect affecting reliability and safety. Please let me know if any additional information or documentation is needed. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

on 2/28/26 i experienced complete engine failure on my 23 Yukon. I was going 70mph on the highway when the engine kicked and and kicked into neutral. the car spent 6 weeks in the dealer to have the engine replaced. i picked up the car on Wednesday, 4/15. On 4/16, i was once again driving, as normal when it suddenly turned off and kicked into neutral. 1 day after I picked up the vehicle it is once again being towed back to the dealer for the same symptoms it had when the entire engine had to be replaced. Both times, there is no warning. The car dings and a message comes up saying "restart vehicle". On 2/28, the car would not restart. On 4/16, the car did restart but only temporarily This is a major safety problem. The first occurrence I was going 70mph on the highway when i lost power. The second occurrence, I was driving 20mph on my neighborhood street and suddenly lost all power.

I previously opened NHTSA Complaint Number11637208 on January 20, 2025 regarding the internal engine failure of my 2021 Yukon Denial XL on January 3, 2025. After filing that Complaint, the engine in my Yukon was replaced by GMC in February 2025. After replacement, the engine was allegedly tested, given an oil cap change, and OK'd by the GMC dealership. On Sunday, April 12, 2026, the replacement engine in my Yukon failed without warning and left me (and my family members, who were also in the Yukon) stranded in the lane of traffic on the westbound College Drive exit of I-10. We had it towed to the GMC dealership (Royal Buick GMC) the same day, they diagnosed it, and according to text communications I received from them on April 14, 2026, the Yukon's engine needs to be replaced again because the engine internally failed - likely due to the failure of the engine's internal rod bearing. No one in my family feels safe in the Yukon anymore. GMC should not be allowed to replace these engines with more faulty engines. If something more is not done soon, people are going to die because of the wrecks caused by these faulty engines.

ENGINE, POWER TRAIN, FUEL/PROPULSION SYSTEM
The vehicle experienced a major engine failure involving the 6.2L engine. The failure appeared sudden and premature and is not consistent with normal wear and tear for a vehicle of this type. Prior to the failure, there were intermittent performance concerns and warning indicators suggesting potential engine or drivetrain issues. The vehicle had previously undergone repair related to similar concerns, indicating a possible recurring problem. The failure created a potential safety risk due to the possibility of loss of power while driving, which could increase the risk of an accident, especially at highway speeds or in traffic. The issue has been confirmed by a service provider, and the vehicle requires significant repair. General Motors has been notified but has declined repair assistance, classifying the issue as wear and tear. While no active recall is currently associated with this specific vehicle, similar vehicles with the same engine platform have documented issues, raising concerns about reliability and safety. The failed components are available for inspection upon request.

March 29th 2026 my 2021 Yukon XL engine stalled while driving at 45mph (No prior warning lamps or messages, restart engine came on dash) causing me to immediately pull over and come to a stop still in traffic, it shifted my vehicle into park, I was in an in an un-safe spot and was stuck in park (conditions not correct for shift on dash) because my vehicle would not allow me to shift to neutral and push it to the side of the road, (could not jump start) Had towed to dealership and mentioned Engine Failure and Fuel pump control module Recalls but according to them it was a starter issue, I asked them to still check the fuel pump control module regardless. Picked up vehicle and a week later April 14th the exact same thing happened vehicle stalled while driving dash said Restart Engine while coasting (No prior warning lamps or messages) forcing me to pull over where it rolled to a stop and locked itself into park leaving me in unsafe conditions again. Had towed back to the same dealership and waiting to hear back from them.
