UNKNOWN OR OTHER, POWER TRAIN
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.

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.

SERVICE BRAKES, ELECTRICAL SYSTEM
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.

ENGINE
On March 21, 2025 my 2024 GMC Yukon Denali's engine died while driving 80 miles an hour down the highway with my family. We were able to coast to the shoulder. The vehicle would not restart. We called a tow truck. When the tow truck arrived the vehicle started but we decided to take the vehicle to closest GMC dealer. They ran diagnostics on the lights that were showing on the dash and nothing was reported. They had no recommendations. We were 3 hours from home returning from Spring Break so we decided to keep traveling. We made it about 120 miles and again the engine died while traveling 70+ miles on the highway. We were able to safely coast to the shoulder. We called a tow truck and the Yukon was towed to the local GMC dealership. The next week it was reported to me that the Yukon would need a new engine. The 1, 3, 5 rod bearing had spun and the 3rd trust bearing had spun. Since there were no rental cars in the city available we rented a U-Haul truck and drove 2 hours home. Almost one month later we are awaiting the new engine to be delivered.

ENGINE
While driving down the interstate the vehicle lost power without warning and gave a command to "press start to resume" tried to do that but nothing happened. Eventually we were able to get over to the shoulder of the interstate which was super busy in Atlanta. Once we stopped, we shut off the vehicle and it started back up, and we proceeded to get back on the interstate, when the same thing happened. We stopped again, waiting a few minutes and were able to get back on the interstate and complete out trip without any issues. 3 days later while driving on the interstate again, the vehicle had a weird winding noise coming from it. Once I was able to get off the instate the engine was knocking very loudly and had no power. Got the vehicle to our home and had it towed to the dealership the next day. Dealership gave the diagnoses that a new engine, radiator and engine coolant lines needed to be replaced. The vehicle had 2,248 miles on it and was purchase 2.5 weeks prior. No eta on when we will have a new engine and our vehicle back.
