2024 GMC Yukon, L87 6.2L V8 VIN: [XXX] This complaint concerns the L87 6.2L engine and NHTSA 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…

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 NHTSA. 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.…

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 Since the incident the engine has been replaced by the dealer but I am concerned that…

2024 GMC Yukon intermittently experiences complete loss of audio while driving. During the failure, all audio sources stop working, including radio/music and incoming hands-free telephone audio. During a phone call, the other party can hear me, but I cannot hear them through the vehicle. When this failure occurs, the audible turn-signal click/clack also does not work. In addition, the audible blind-spot warning does not sound. The visual indicators continue to function, but the associated audible warnings are lost. The condition is intermittent but persistent and can last 30+minutes. GM has issued a technical service bulletin addressing loss of audio together with loss of the turn-signal…

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 itâs 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.

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…
