2024 GMC YUKON Complaints

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.

I am filing this complaint regarding GM Recall N252494000 (NHTSA Campaign Number 25V274) for my 2024 GMC Yukon XL (VIN: [XXX] ). The issue involves a serious engine defect related to the crankshaft and/or connecting rods, which can result in catastrophic engine failure and loss of propulsion while driving—a clear and dangerous safety risk. I first became concerned when early reports of this issue began circulating publicly. As a father of young children, I became increasingly uneasy that my vehicle could potentially fail while in operation. Receiving GM’s formal recall letter only validated my growing concern for my family’s well-being. It’s deeply frustrating and unsettling. The notice states that parts to repair or replace the engine are not currently available, and offers no clear timeframe for when a remedy will be provided. I feel like we are being strung along while forced to continue using a vehicle that may become unsafe at any moment. This delay is unacceptable. There has been no offer of a loaner vehicle, no proactive communication from the dealer, and no assurance from GM that they are prioritizing driver safety over logistics. I am requesting that NHTSA investigate whether GM is doing enough to provide timely remedies to affected customers. I also urge you to consider whether interim solutions (such as alternative transportation or more aggressive recall execution) should be mandated. Thank you for your attention to this matter.

There currently is a serious recall on this vehicle and there is no remedy available. I’ve called the dealership and they confirmed this information. The service department claimed the sales department may be able to help me and then sales said it was a service dept issue. I have children who have been placed at risk as they have been traveling in this vehicle since April 2024.

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.

The contact owns a 2024 GMC Yukon XL. The contact stated while driving approximately 65 MPH, there was an abnormal bang coming from the vehicle and the contact became aware that the front section of the sunroof had exploded. The contact stated that there was no other vehicle nearby. The contact stated that the sunroof sprayed glass fragments onto the instrument cluster, front seats, and rear seats. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the sunroof glass needed to be replaced. The vehicle was being repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 8,000.
