2024 GMC Yukon, L87 6.2L V8 VIN: [XXX] This complaint concerns the L87 6.2L engine and the federal safety agency Engineering Analysis EA26005 regarding engine failure following the remedy for Recall 25V‑274. My vehicle underwent the GM recall inspection, including the Pico test, and passed the inspection. The engine was therefore not replaced. Since completion of that inspection, I have continued to obtain abnormal used-oil-analysis results showing excessive and increasing engine wear metals. At the most recent oil change, I cut open the engine oil filter and found visible metallic swarf/debris embedded in the filter media. I have retained the oil filter media and have photographs documenting the metallic debris. I also have the previous oil-analysis reports documenting the wear-metal trend. The engine has now developed a loud knocking noise. Because of the knocking noise, documented abnormal wear metals, and visible metallic debris in the oil filter, I no longer consider the vehicle safe to operate due to the possibility of sudden engine failure and loss of propulsion. The significant concern is that this vehicle passed GM's Recall 25V‑274 screening procedure but appears to be developing the same type of internal engine deterioration that the recall was intended to identify and prevent. I am requesting that the federal safety agency associate this complaint with Engineering Analysis EA26005 and review this case as a possible post-remedy failure of the Recall 25V‑274 inspection procedure. Supporting evidence available includes: • Used-oil-analysis reports showing excessive and increasing wear metals • Photographs of metallic debris/swarf in the oil filter media • Retained oil filter and filter media • Dealer repair and recall records • Mileage and oil-change records • Current loud engine knocking noise The vehicle is presently not being driven because of the potential for engine seizure or sudden loss of propulsion.

What 2024 GMC Yukon owners say
Most recent owner complaints, unedited.
My 2024 GMC Yukon Denali has experienced repeated and serious stalling, restart hesitation, shutdown, and loss-of-propulsion issues that have created an ongoing safety concern for me, my children, and other drivers. On one occasion, while I was actively driving with my children in the vehicle, the Yukon completely lost propulsion and died. I was only able to coast/roll the vehicle to a complete stop because it no longer had power. I previously reported that incident to the federal safety agency. Since then, there have been numerous additional occasions when I have been driving and come to a stop at a traffic light, stop sign, or in traffic and the vehicle has stalled or seriously hesitated before restarting. On September 23, 2026, while driving with my children in the vehicle, I stopped at a red light in heavy traffic. Without warning, the vehicle completely shut off, shifted into neutral, and displayed a message instructing me to restart the vehicle. I had to manually restart the Yukon before I could continue driving. This was the first time while stopped that the vehicle completely shut off, went into neutral, and required a manual restart. During these incidents, my children were in the vehicle and I was surrounded by other vehicles and heavy traffic, creating a serious safety concern. GMC has been repeatedly notified about these issues. Despite multiple complaints and prior repair attempts, the problems have continued and GMC has not provided a meaningful resolution. The cause of the most recent failure is currently unknown.
After having the recall inspection completed and changing to the recommended higher grade of motor oil, 0W40, my engine failed while driving on a major highway. We were traveling at high speed on a busy highway when the engine failed and the Yukon shifted into neutral leaving me little time to pull off the road. When the failure occurred the Yukon shifted itself into neutral and a message appeared telling me to press start again. I was able to get to the side of the roadway and called the State Police for assistance. Six of us stood on the Side of this major highway for 90 minutes waiting for a tow truck. Since the incident the engine has been replaced by the dealer but I am concerned that this may happen again. After the recall inspection they tell you that you are ok but clearly you are not, you are still in danger.
Our Yukon was taken in for the recall. Dealer did the test and said it passed and used different oil. My wife and kids were driving to [XXX] from [XXX] yesterday. As they exited the highway, the car began acting weird. Then the car completely died. It was towed due to error code P0016. Dealer said they are going to put a new engine in. I saw online that cars with replacement engines were failing too? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Issues with the google voice, transmission issues, engine failure to start or restart. Reported same year vehicle was bought. Repeatedly. Dealership even with video evidence stated could not repeat issue and nothing wrong. My car then starts rattling in the engine and they do a full replacement had it for over three months. Now it’s leaking fluid and smoking. They try to send the consumer away and delay delay until the warranty is over. Unethical practices. They knew there was an issue with my engine as it was on the recall list but kept denying any issues until complete failure. Now less than 20 days after that repair the car is leaking and smoking.
Vehicle has 43k miles on it and a has a failed oil pump, already switched to the heavier oil and still have engine issue
My 2024 GMC Yukon Denali equipped with the 6.2L L87 V8 experienced an engine failure on July 4, 2026. Prior to the failure, there was no visible damage, warning, or other evidence that the engine was about to fail. I drove the vehicle to purchase fireworks and shut the vehicle off normally when I arrived. When I returned to the vehicle after shopping, the engine problem became apparent. There had been no noticeable indication of an engine failure before I turned the vehicle off. The vehicle was subsequently taken to a GM dealership, where the engine failure was confirmed and ultimately required replacement of the 6.2L L87 engine. The vehicle remained out of service from July 4, 2026, until it was returned to me on August 21, 2026. The original failed engine was in the possession of the servicing GM dealership I purchased the car from. Not even 8 months later of purchase the vehicle needed a 3rd engine (original, recalled engine, warranty engine). The lack of warning before the failure is a significant safety concern to me. The vehicle had been operating immediately before I parked it, and there were no apparent symptoms that would have alerted me that a major engine failure was imminent. Had the failure occurred while the vehicle was traveling at highway speed or in traffic, the sudden loss of engine operation could have created a dangerous situation. The failure was confirmed by the GM dealership and resulted in replacement of the L87 6.2L V8 engine. I am submitting this complaint to document the failure and because of continuing concerns regarding the L87 6.2L V8 and the effectiveness and long-term reliability of the recall remedy. I am still currently waiting for the repair work documentation for the new (assuming it was new) motor. I have attached attempts to talk to GM, app incidents, repair work being completed.
Complete engine failure, recall was performed before engine failed on highway with family inside.
Hello, I own a 2024 GMC Yukon Denali with the 6.2L V8. Car currently has 35,000 miles on it. At about 30,000 miles we started to feel a very aggressive vibration in the passanger seat, as well as the 2nd row seats, and driver seat. We took the vehicle in for the recall on the engine where we were instructed to put 0W-40 oil in. Much higher vescocity. After we did this recall the vehicle has not stopped shaking. We went for another service visit in July where we were told " this is the engine pistons trying to conserve fuel, and are firing causing the vibration." I have worked in the auto industry for 12 years, this is not a normal vibration. This should also not be caused by an engine. We then took it in again where they then proceeded to replace fuel manifold on August 18th. The vehicle shakes a bit less but still has a aggressive shake to it. I do not believe this is normal and if it is the engine pistons firing or the crank shafts misfiring, this could cause the engine to have catistrophic failure. This shake happens at speeds anywhere from 18 MPH to 50 MPH. My concern is with my wife and kids in this vehicle as the daily driver and this engine fails.
Driving about 75 mph car shuttered and motor quit running had to pull off of the highway and get towed to dealership. Motor had to be replaced due to 1,2,6,7 rod bearings spun on the crankshaft. 34367 miles
