On October 10, 2026, at approximately 5,200 miles, our 2026 GMC Yukon Denali XL equipped with the 6.2-liter V8 developed a sudden, severe abnormal engine noise. The servicing dealership subsequently advised us that the engine had suffered a rod-bearing failure and required engine replacement. The service manager stated that the failed engine would be returned to General Motors and that the dealership could not determine the full extent of the internal damage. We have not received a confirmed explanation of the underlying cause. The vehicle has remained out of service since the incident. We were subsequently told that a replacement engine had shipped, but we have not received confirmation that repairs are complete. We are reporting this premature internal engine failure for the federal safety agency’s review as a potential safety defect.

What 2026 GMC Yukon XL owners say
Most recent owner complaints, unedited.
We own 2026 GMC Yukon XL Denali with 6.2L V8 engine with just under 4600 miles. On Monday October 19, 2026 while driving the engine seized up. It is at dealer and the are replacing the engine, radiator and about 65 other parts under hood. We do have a very short phone video of the noise it made right as it seized up!! We heard about investigation ongoing and wanted to help.
The driver side head light developed a stress fracture on the first cold day we had in Long Island. It has been looked at by the dealer SuN gmc who are denying responsibility and claiming it was damaged by a rock. There is no visible damage to the outside of the light.
Truck has shuttered, rough idle since May 2026 after purchased new March 2026. We have been to two different GMC dealers who cannot duplicate the problem. Last week the truck started to shutter regularly after highway travel. When coming to a stop in traffic, the truck shutters to kill, loses power, RPMs drop below 500 and then recovers to a rough idle. Last evening Oct 20,2026 while driving the engine light came on, vehicle computer stated “ Issue with Engine / Transmission System Schedule service now.” This is the third time the vehicle will be at the GM dealer for diagnosis. Two times previous, dealer stated “unable to duplicate customer’s complaint.” We have owned this 2026 GMC truck for 8 months, purchased new and have nothing but issues which no GM dealer seems to be aware of nor can duplicate. This vehicle is unreliable and now has sat out of service awaiting a diagnosis for over 15 days at two different dealers. We have opened our second case with GMC Customer Care’s with zero assistance. It is the duty of a manufacturer to provide consumers with a safe and reliable vehicle. My 2026 GMC Yukon Denali is not safe and puts me and my family at risk of engine failure and a potential accident. We have documented every event and have videos of described defective vehicle operation.
While driving there was a noise that started in the engine area. The vehicle was going 55-60 mph at the time it started. It became more and more frequent. The check engine light came on just before the engine completely seized up and lost all power. Dealership is saying there is definitely internal engine noise and engine failure.
I’m of average stature at 5’ 9” and when seated in the driver’s seat of my 2026 GMC Yukon Denali XL my left eyeball cannot see the switch to activate the four way hazard flashers because the steering wheel blocks the view of the switch. (See Attached) I’ve had the vehicle for just over two months and I found it difficult to find the hazard switch since day one. It was even more challenging tonight coming home. I was northbound on IH35E just south of IH20 in heavy traffic and the traffic rapidly came to a stop due to a crash. It took an extra level of attention to find the hazard switch at night in heavy traffic. After I cleared the accident I started to close one eye and then the other. That is when I recognized my left eyeball is completely blocked by the steering wheel. There is plenty of room to move the switch over an inch or two so both eyeballs can see the switch with stereoscopic vision. Even in the daytime I struggle to find the switch once again from the placement of the switch and during the daytime the switch isn’t illuminated and the color of red isn’t a very vibrant red.
Total Engine failure. This is the second time. The vehicle had under 2000 miles when the first engine failure happened and left us sitting on the Turnpike. Very unsafe!! We were assured we received a new "upgraded" engine only to find out GM decided to roll the dice with our lives and the lives of our family (grandchildren) and put another bad engine in our vehicle. I will never feel safe with this vehicle or that they are putting in "new" parts.
