2024 GMC Acadia grounded at dealership for 3+ weeks due to unavailable driver seat belt buckle (Part 26522477), rendering a brand-new vehicle legally un-driveable due to primary restraint part constraints. The buckle will not latch, causing the seat belt to be rendered inoperable. The problem was reproduced by the dealership, and the replacement part is backordered.

The contact owns a 2024 GMC Acadia. The contact stated that while back out of his driveway while in reverse(R), the contact hit another vehicle that was also parked in the driveway. The contact stated that back over prevention sensor failed to alert him that a vehicle was in his vicinity; also the vehicle did not apply the automatic braking system when closely approaching vehicle. The contact stated that the failure cause significant damage to both vehicles involved in the collision. The vehicle had yet to be diagnosed or repaired for the failure. The dealer nor the manufacturer had yet to be notified of the failure. The failure mileage was approximately 17,500.

My complaint does not involve an accident. The brakes on the 2024 Acadia Elevation are squealing very loudly, and have been doing so for the past six months or so. I have approximately 18,000 miles on it. I took my vehicle to the dealership twice for this issue, and I was told this time that the brakes are still good (still 8mm of pads) - even though it was showing 22% brake pad. They told me about the malfunctioning sensor and they fixed that, but the squealing is still there. I was told that it was the metal composition of the brake pads that is making that noise, and GM does not cover brakes past 7,500 miles (this 7,500 warranty is pointless because who would need brakes replaced in that short time frame, anyway?). That means I would have to pay out of pocket for the brakes! There is clearly something wrong with the structure of the brakes and I see on the Acadia forum that this is a common complaint. If the brakes are good, then why are the brakes squealing? Why am I being told that I just have to deal with the squealing sound? What can be done about this issue. It seems unfair to me that I have to come out of pocket to fix something that should not be "broken".

I purchased this vehicle in June 2024 as a demo vehicle with approximately 7,000 miles on it. Within one month of ownership, the vehicle began experiencing serious problems that have continued to worsen. The vehicle currently has approximately 34,000 miles, and the issues have been ongoing from the time of purchase through the present. Since purchasing the vehicle, it has been in the dealership multiple times for the same recurring problems, including but not limited to: * Powertrain issues and loss of power * Reduced acceleration while driving * Complete electrical failure while driving * Engine and electrical warning lights repeatedly turning on * Vehicle running excessively hot * Water pump replacement * Replacement of sensors * Thermostat replacement * Ongoing engine and electrical system malfunctions Despite these repairs, the same problems continue to reoccur. Each time I return the vehicle for service, I am informed that it is a “different issue,” even though the symptoms remain unchanged. This strongly indicates a defective powertrain and/or electrical system that has not been properly repaired. The most serious concern occurred while I was driving on public streets, when the vehicle lost acceleration, electrical power shut off, and the vehicle completely shut down, nearly causing me to be hit by other vehicles. This incident created an extreme safety hazard for myself, my passengers, and other motorists. I have made several formal complaints directly with GMC, and more than four case numbers have already been created regarding this vehicle. Despite these complaints and repeated repair attempts, the problems persist. Given the repeated failures, numerous repair attempts, documented safety risks, and the fact that these issues began shortly after purchase, I believe this vehicle qualifies for relief under applicable lemon laws and consumer protection laws.

We purchased our 2024 Acadia in June 2025. Since we have had the vehicle, it has been in the shop going on 6 times. First the sunroof seal came off, then the antenna cover fell off, the driver side rear panel had to be replaced because it was coming off. Once all this was done then the vehicle started leaking transmission fluid, took it to the dealer to get fixed, once we get it back the coolant starts leaking from the radiator hose, took it in to get repaired, now there is knocking noise coming from the engine/hood. Every time we take it in to get repaired a new problem pops up. We purchased the vehicle to have a safe way to get our kids around and it has been nothing but a headache and run around from the dealership. GMC really needs to resolve this issue. Parts seem to be on never-ending backorder with no ETA.
