I am filing a complaint regarding a potential safety defect in my 2024 GMC Yukon Denali (approx. 25,000 miles), which has been in the dealership’s service department for about 30 days due to a faulty valve body in the transmission system. There is currently no estimated date for repair completion due to a lack of available parts. This is the second time the vehicle has been in the shop for the same unresolved issue. Earlier in 2025, I brought the car in due to driveability concerns and error messages appearing on the dash, but the dealership dismissed it and claimed I had “turned the vehicle on wrong,” despite it having a push-button start. The problem persisted until June 2025, when they finally diagnosed the valve body failure. This issue directly affects drivability and vehicle safety, particularly during acceleration and gear shifting. I am concerned that General Motors is aware of widespread valve body and transmission failures in these vehicles, yet continues to produce and sell new units while failing to ensure parts are available to support timely repairs. It is unacceptable that a major safety-related transmission issue can sideline a relatively new vehicle for over a month with no resolution in sight. GM’s lack of urgency in addressing this defect suggests a disregard for consumer safety and reliability. I respectfully request that the NHTSA investigate this issue as a potential pattern of safety defects in GM’s full-size SUV transmission systems.

Since purchasing the vehicle in September with 8 miles there have been several electrical malfunctions. Some “fix” themselves when I restart the vehicle and several have needed to go into service. The first issue was when my mirrors wouldn’t come back up when switching to drive. I disabled the reverse tilt option and had it serviced to be fixed. Apparently it needed an update. More recently I had several malfunctions. My vehicle would lower its self while still in gear, and it wasn’t the normal self leveling. I didn’t not have any warning lights or messages pop up. The next time I started my vehicle and had “service rear axle” warning. I called the local dealership and after restarting the vehicle several times and more error messages, I decided to attempt to drive the vehicle in, all the while recovering several message warnings. On the way I was increasingly loosing brakes and I rolled into their parking lot with no breaks. Since this episode I have had repeated lost connection codes without dash warnings. They first attempted to reprogram the brake control monitor. Then when it continued to lower itself and have other malfunctions it went back into service. They replaced the serial data gateway and reprogrammed it. Since then the vehicle is having lost communication codes every day. It is currently in service to try and figure out what’s causing it and hopefully fix it.

EA26005 · Loss Of Motive Power Due To Engine Failure Post Recall Remedy

Opened Aug 20, 2026 · No close date supplied

Status: open (inferred from source dates) · Engine

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.

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.
