The gauge cluster flickers and goes blank completely while driving, over head windshield screen display still works, and throws an - Accretion speed limited- message. Truck has electronics software issues, climate control flickers, works sometimes, most times doesn’t, loose electrical connections. Over all the gmc truck is a major software glitch and GMC does not want to take accountability for there lemon product which is very costly in repairs. Gmc service is not great and the warranty period of 36,000 miles is not justifiable. My truck has 68,000 all highway miles, not city miles. 2024 gmc Denali top in its class, and still has more issues than my 2007 gmc Sierra

While operating my 2024 GMC Sierra EV Edition 1 at approximately 21,000 miles, a "Service Power Steering" warning appeared. Steering effort initially increased and then rapidly progressed to a near-complete loss of power steering assist. The steering wheel became extremely difficult to turn, making anything more than a gradual sweeping turn nearly impossible. I was able to safely exit the roadway into a parking lot. After shutting down and restarting the vehicle, steering assist returned to normal. No crash or injury occurred, but I believe this represents a significant safety risk because loss of steering assist at highway speed could result in loss of vehicle control.

Vehicle lost power, seemed to slip while pulling hills, Exhaust brake didn't seem to work. Dealer determined cause by DTC P209. Tested injector circuit, found loose terminal tension at injector number 6 connector. Replaced Cylinder # 6 injector connector. Did have multiple warning lights. Also submitting because Service Bulletin 23-NA+027 covered up to 2023. Believe it's an ongoing issue since vehicle is a 2024.

I am reporting a recurring potential safety defect involving the front fender liners on my 2024 GMC Sierra 3500. The vehicle currently has approximately 10,000 miles. During that time, at least five front fender liners have been replaced across both sides of the vehicle for the same recurring problem. During highway driving, the front fender liners appear to lose their intended shape and rigidity. Portions of the liner deform or move inward and make physical contact with the rotating front tires. The condition has continued to recur despite multiple replacement liners being installed. I am concerned that continued contact between the liner and tire can generate friction and heat and could potentially cause damage to the tire, liner, or surrounding components. Because the condition occurs at highway speeds and involves direct contact with a rotating tire, I believe it represents a potential safety issue rather than simply a cosmetic or durability problem. Replacing the liners with the same components has not permanently corrected the condition. After approximately five liner replacements in only 10,000 miles, I am concerned there may be an underlying issue involving the liner design, material rigidity, mounting method, or aerodynamic forces acting on the liner at highway speeds. I have reported the recurring issue to GMC/dealer service and am requesting that the manufacturer investigate the underlying cause rather than continue replacing the liners with identical components. I am submitting this complaint so that NHTSA has a record of the repeated failures and can determine whether similar incidents have been reported on other 2024 GMC Sierra 3500 vehicles and whether the condition warrants further investigation.

integrated trailer brake control system goes in and out of working order while towing either one of my trailers. one being a boat trailer and the other being a travel trailer. Have taken to local GMC dealer several times and they changed the rear plug the first time, which did not fix the issue. big safety concern if I can't stop my vehicle and what I am towing. Dealer claims it is most likely trailer issue but both these trailers brakes work perfect when towed with other truck. I see that they are having a big problem with this but they claim my VIN number is not included in the recall. Yet I am having the exact same issues. I get on and off warnings TRAILER BRAKES DISABLED SERVIC REQUIRED 10 to 30 times during a one day drive. And yes the trailer brakes do not work when this happens

Battery voltage low and required a jump to start. Advised battery had to much resistance. Drove to dealership. Upon pulling out on to highway without warning sudden engine loss and stalls. Steering column locked and shortly after the brakes locked up making it to where the vehicle could not be moved. This is a major safety issue and WILL lead to a fatality. My drivers side door exposed to oncoming traffic on a highway. 2 tow trucks, multiple technicians to coordinate keeping jumper cables on long enough to keep the brakes functioning to move the vehicle. Once the power was lost the vehicle seized. This happens on an actual interstate or railroad crossing YOU WILL HAVE FATALITIES!! This vehicle needs an immediate recall and pulled off the road! It took 6 hours to get this truck moved! This happens on the interstate or railroad crossing and sits for that duration due to everything locking up people will die as a result!

Since I purchased this truck in 2023 brand new as a 2024 the shifting has been very abrasive. It shifts far excessively harder than it should and I have brought this to the dealership’s attention many times. Now I am finding out that there is a massive recall on this vehicle’s transmission because of these issues that have been happening. The error codes are P0700 and P0747 The Engine and Transmission System is not performing as expected. An issue has been detected in the Transmission System that transfers power from the engine to the drive wheels. You may experience reduced power or shifting issues.If the vehicle is continually driven with the check engine light on, the emission controls might not work as well, the vehicle fuel economy might not be as good, and the engine might not run as smoothly. This could lead to future repairs.

Incident: September 20, 2025 · Filed: July 16, 2026

"The integrated trailer brake system abruptly fails while towing heavy loads, completely disabling trailer break stopping power and creating an imminent threat of highway crash and serious bodily injury." The sound system inherently stops working and will not produce sound from any device in the truck weather that be Hazards, Blinkers, Radio including AM,FM, Sirus Radio, Bluetooth or Car play as well as OnStar. The truck has been taken to a certified GMC dealer 4 times for these exact issues with also being provided the service bulletin information #N232414840 dated July 16, 2025 stating that the 2024 gmc 2500/3500 HD trucks requiring a new Trailer Break Control Module. This issue has been on going from September 2025 and still an issue as July 16, 2026 and still in the Shop today with a call back stating ready for pick up with the same module but dealer stated re flashed module. ( this is the 3rd reflash )
