On [XXX], while driving on the [XXX] Highway with my family, the vehicle automatically shifted into neutral and I lost control of the accelerator pedal. I safely changed lanes and pulled over to the shoulder. Once in park, the vehicle never started again. We were stranded on the side of the road until my husband and a tow truck returned to collect my family and tow the vehicle to the Fairbanks dealership. The engine was diagnosed as an engine failure requiring complete engine replacement. We are a military family and were on orders to move our household on [XXX]. We did not have any other option but to trade in the vehicle and purchase a new one. Had I been driving on a road that did not have a shoulder or the traffic too congested to safely change lanes, my family could have been in significant danger for a motor vehicle accident.

January 16, 2025: Driving down the interstate near Atlanta Ga going 75 MPH, our 2023 Yukon Denali with 28,585 miles on it, abruptly started gearing down. The vehicle would not accelerate, it was coming to a stop on its on. Traffic was very heavy and it was a very scary situation. After managing to get the vehicle barely off the interstate it totally lost power and would not start. The vehicle was towed to the local GMC Dealership and within 30 minutes they told us the engine had locked up. We had to get a rental car to continue our trip and haven’t had much luck, so far, getting reimbursed. As of today February 6th, GMC cannot give us an estimated repair date as our engine is on back order!

Engine failed on highway while my wife was driving with 3 kids aged 5 and under. Had to pull over on shoulder. Called GMC roadside and they said they would be there in 2 hours. Then a police officer came by, told her she was in too dangerous of a spot and that the police would be towing the vehicle in 20 minutes if she didn't move it. Police then towed the car while my wife, on the shoulder of a busy highway, had to frantically move the 3 kids and their car seats into a friends car. Got car towed to GMC and they did a full engine replacement. No warning lights, no signs of malfunction, and car had about 4k miles on it at the time.

The Office of Defects Investigation (ODI) has received 1,157 reports of engine bearing failure failures in the L87 6.2L engine produced by General Motors (GM). Of the 1,157 reports received, 173 are outside of the scope of recall 25V-274. These engines are installed in Model Years (MY) 2019–2024 Chevrolet Silverado 1500 and GMC Sierra 1500, and 2021-2024MY Chevrolet Suburban and Tahoe, GMC Yukon/Yukon XL, and Cadillac Escalade/Escalade ESV vehicles. The subject engine failures were investigated as part of a Preliminary Evaluation (PE25001). GM determined that these engine failures were due to multiple supplier manufacturing and quality issues. GM issued recall 25V-274 to address the supplier manufacturing and quality issues produced between March 1, 2021, and May 31, 2024. Based on the issuance of recall 25V-274, NHTSA has closed PE25001. ODI continues to receive a significant number of reports of engine failure in vehicles outside the scope of 25V-274. This presents a potential safety risk that warrants further investigation.
