2026 GMC Yukon

On January 16, 2026, the Office of Defects Investigation (ODI) opened Recall Query RQ26001.  This investigation was opened to assess the remedy effectiveness of Recall 25V-274. ODI has received complaints alleging engine failure in vehicles after the recall remedy had been completed, whether that remedy involved an oil viscosity change or a complete engine replacement. General Motors (GM) issued Recall 25V-274 to address concerns of engine failure in the L87 engines produced between March 1, 2021 and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issue. GM’s recall remedy for Recall 25V-274 consisted of two different repairs, either an oil viscosity change or an engine replacement, based on the results of the remedy inspection procedure. ODI continues to receive reports of engine failures after the completion of the recall remedy. To date, ODI has received 499 complaints alleging post-remedy engine failure in vehicles subject to Recall 25V-274, 473 of which involved an oil viscosity change and 26 a complete engine replacement. Additionally, ODI has received 191 reports of L87 engine failures in engines produced after the production period cited in Recall 25V-274. GM reported receiving 6,953 complaints of post-remedy engine failure. ODI is opening this Engineering Analysisto continue investigating complaints of post-remedy engine failure. ODI is expanding the scope of this Investigation to include engines produced after the production period cited in the recall. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

My 2026 GMC Yukon Denali Ultimate with the 6.2L V8 had a major engine failure on November 2, 2026, while driving with only 3,668 miles on it. I bought it brand new in July. The dealership told me it was likely a rod or rod bearing failure and found metal in the oil. The entire engine has to be replaced. This is a serious safety concern, especially if the engine fails while driving at highway speeds. A brand-new vehicle should not have a catastrophic engine failure with less than 4,000 miles. I’m concerned other 2026 Yukons with the 6.2L engine could have the same issue.

Engine Failure. While driving on the highway at a speed of approximately 70 mph the engine made a noise and the vehicle lost power. The safety factor is that i was on the highway with trucks and busses in which i had to coast the vehicle to the shoulder of the road and call for police assistance. No warning lamps. Vehicle was towed and inspected by the dealer in which i was informed that the engine bearings had locked up. The vehicle needed a new engine.

I am writing to formally report what I believe is a design flaw in my new GMC Denali involving the center console lid. The lid does not have a stopper, dampening mechanism, or other means of holding it securely in the open position. When I lift the lid to reach for an item inside the console, it can fall closed unexpectedly and slam down on my hand. This creates an avoidable risk of injury during ordinary use of the vehicle. Accessing a center console storage compartment is a routine activity, and the lid should not unexpectedly close on the user’s hand. I am concerned that this design may affect other owners of the same vehicle model. I believe the issue warrants review by GMC’s product engineering and vehicle safety teams

My 2026 GMC Yukon Denali Ultimate has had the vadar chrome peel in the first 7000 miles. After that a wiring pinch made the 4 wheel drive unusable during the winter months that I needed it to get into my driveway During summer months the infotainment center completely failed to a black screen and since does not function having the dealership tell me that it will need to be replaced. The 6.2 motor started ticking at 25000 miles, I took it to the dealership yesterday 10/14, the dealership is keeping the vehicle for an estimated 6 weeks to tear the motor apart. The motor is making the noise where it is reported to shut down at high speeds had I not got it in when I did. The vehicle has had no warning to indicate problems.
