my 2023 GMC Yukon Denali (VIN: [XXX] ), which is included in Safety Recall N252494003 for a known defect affecting the L87 6.2L V8 engine. My vehicle was first inspected under warranty in December 2024 at Serra Traverse City Buick GMC due to a burning smell. I was informed at that time that no issues were found. I was later told by the former service manager that the technician who evaluated my vehicle during that visit was let go due to poor workmanship and lack of product knowledge. Since that time, on two separate oil changes — January 8, 2025 and May 9, 2025 — my engine was found completely out of oil, with no oil on the dipstick. The documentation had to be retroactively added after my request. This pattern raises serious concerns about oil consumption or internal engine damage consistent with the recall defect. The dealership declined to replace the engine or perform any further diagnostics beyond the standard recall inspection. I was advised to retrieve the vehicle. However, I remain deeply concerned about the long-term safety and reliability of this vehicle, especially given GM’s acknowledgment that this defect may lead to engine failure and loss of propulsion. I have made multiple efforts to escalate this issue through both the dealership and GM’s customer service line. I was advised by Service Advisor [XXX] to contact the GM representative for regional review. He directed me to file a bbb claim.. Both GM and bbb denied my claim, stating out of warranty. However, the dealer explained that my issue were documented under warranty and would be handled appropriately if the issue persisted. GM contacted me an offered a $4000 credit. Unfortunately the problem still persist. I’m 3000 miles from being due for an oil change and again have no oil on my dipstick.

Electric trailer brake control module intermittently disabled trailer electric brakes while towing electric brake equipped trailers. This is the same issue addressed in GM service bulletin N232414840 which addressed a similar issue associated with GM pickup trucks. The loss of trailer brake utilization may create a safety hazard resulting from longer stopping distances. The factory control module was replaced with a redesigned module purchased from GM and the problem went away. I am of the opinion that the factory-provided module is a deficient design which warrants replacement by the vehicle manufacture.

The contact owns a 2023 GMC Yukon. The contact stated that while driving 75 MPH and depressing the accelerator pedal, there was an abnormal clunking sound coming from the front of the vehicle; however, the contact was unsure if the failure was coming from the engine or transmission. The contact pulled over to the right side of the road, exited the vehicle, and inspected the vehicle, but found no failure. There was an unknown warning light illuminated. The contact stated that the failure had occurred on four occasions. An unknown dealer was contacted. The vehicle was taken to a dealer, where it was diagnosed, and determined that the valve body needed to be replaced. The valve body was replaced. The manufacturer was not notified of the failure.

After stopping at a stop sign, I accelerated for a few seconds, but then it shifted to Neutral and the screen said "Press Start Again". I pressed Start, accelerated for a few seconds, and again it shifted to Neutral and the screen said "Press Start Again." I repeated this process a few times and luckily made it to the end of our driveway. I could no longer move the car nor could I shift gears. When trying to shift gears, the screen said "Conditions Not Correct for Shift." I requested Roadside Assistance. There is no way to get this car into neutral so he had to manually pull it onto the tow truck bed. The nearest dealership diagnosed it as engine failure and replaced the engine. There were no warning signs prior to this incident.

At this time (8-30-25) they are not allowing the dealers to perform these inspections. Why can't they at least perform the inspection to see if in fact the Engine will not need to be replaced?

we brought my 2023 gmc yukon into Parks GMC in greenville sc on july 26, 2025 for the engine recall that we received a letter from. We left it as we were going on vacation for the week and picked it up the following saturday august 2nd. the next week my engine light started lighting up and my husband contacted the dealership and we were asked to bring it back in. We did and were told that we now had a bad Telematics Communication Interface Control Module that was causing my engine light to come on and that we were going to have to pay $600.00 out of our pocket to have this repaired. After researching we found that this is a VERY common and widespread problem with a lot of owners right after they bring their vehicles in to be serviced. We declined the repair, one because they did not have the part in stock as that apparently is also a big problem of not being able to get the part in stock and two because we feel like we should not have to pay to have this part replaced as it appears to be a widespread issue that is happening. The dealership also charged me $182 for diagnostic charges that I once again feel like we should not have had ton pay. Please advise us asap. our contact info is [XXX] [XXX] & [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

1. First incident While driving, the brakes failed and the entire infotainment/tablet system locked up. This presented a severe safety risk to my family and others on the road. The vehicle had to be towed to DEALER where I was told that “no problems were found.” I documented the incident with photos and videos showing the warning messages and system status. 2. Second incident Approximately one week ago, after shutting off the vehicle, a “steering wheel lock” warning appeared and the truck became completely disabled. Even with jumper cables, it would not start. The vehicle had to be flatbed towed to DEALER. I again documented the incident with photos and videos showing the warnings.

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.
