“The contact owns a 2024 GMC Sierra 3500. The contact stated that while the vehicle was parked, the contact attempted to start the vehicle however, the vehicle failed to start. Upon inspecting the vehicle, the contact became aware that the battery was drained. The battery was recharged. The contact stated that while driving, there was an abnormal odor inside the vehicle. The vehicle was taken to the dealer where it was diagnosed and determined that the battery was overheating. The contact was informed that the battery needed to be replaced. The vehicle was repaired. The manufacturer was contacted and made aware of the failure. The contact was informed that an incompatible battery was installed in the vehicle. The failure mileage was approximately 48,000.”
“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”
“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”
