GM is not handle this recall in a timely manner. They are refusing to inspect vehicle to see of there are any defects. This is concerning, as based on the recall notice, the engine may fail at anytime. This could cause a crash or leave me or my wife stranded on some road. My dealer would do the inspection but to do the inspection but they said they are not allowed until I have gotten "permission" from GM. This is a safety concern for me and my family and GM is not handling this appropriately. An immediate inspection should be done ensuring if the vehicle is safe to drive.

Engine was making noise and ultimately stopped responding when I would push the gas, leaving me stranded on the side of the road. Luckily, I was able to get the vehicle off the road in time to not cause an accident. The vehicle could have stalled and seized up in the middle of the highway. This problem has been confirmed by the dealer in the attached work order invoices. It has not been inspected by anyone other than the Mountain Chevrolet dealership, to my knowledge. The dealership has the vehicle running again, but is not able to confirm if the 'new' engine in my vehicle is the one address the recall issue, reference number N252494000. Additionally, this vehicle broke down again two months later for a related issue per the additional service invoice attached. For all of these, GM has not been willing to pay for the full value of the rentals for each service, totaling over 60 days without my vehicle. I've requested this through the GM Customer Care to no avail. I would also like to receive confirmation that the 'repaired' engine in my vehicle resolves this open recall concern. I've been stranded on the side of the road twice now with this newer vehicle and would love some assurance from them. At a minimum I want GM to pay for the full value of the rental cars. For the record, I also requested GM buy-back the vehicle which they have rejected my request. Any help you can provide is appreciated. Thank you.

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.

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. ODI is opening this Engineering Analysis (EA) to further evaluate the scope and severity of the potential problem and to fully assess the potential safety-related issues of vehicles built outside the recall scope.
