2024 Gmc Acadia Complaints

Since we bought the 2024 GMC Acadia in November 2024 when we would get the oil changes we have to dealership to check the brakes because the brakes were always squealing. They inspected and gave us a vehicle back chalking it up that the brakes are fine. they did a multiport inspection three different times and didn’t find any issues with the brakes. The last multipurpose inspection was done in September 13 2025. on December 8, 2025 I took ivehicle to another mechanic. I had to replace all four brake pads. The front brake pads were down to below 20% and the back brake pads were right at 50%. on January 7, 2026 I had to take the vehicle in to the dealership because another brake problem after a week of half. They found out that the electronic brake control module was faulty on the master cylinder. The dealership had to replace it.

I experienced the brakes squeaking on and off for a few weeks this past summer. When at the dealership for an oil change, I was told the brakes pads were still good and the squeaking is common, especially during hot humid weather. Since then, I have lost the brakes twice. Both times, the pedal went all the way to the floor without resistance and after a few seconds, they came back like nothing happened. There was no warning at all. I have also experienced a complete blackout on my dashboard for about 30 minutes without known reason. On a separate occasion, the battery died for no reason. There have been times that a message is displayed on the dash to service rear turn signal lights. They flash fast as if they were out, then the next time I drive the car, they are completely normal. From what has been reported, there are some serious concerns with the 2024 Acadia. I have leased 3 Acadia's before this one and have never experienced anything like this. The brakes failing completely could...

The contact owns a 2024 GMC Acadia. The contact stated that while driving at various speeds, the vehicle hesitated while coming to a stop while depressing the brake pedal. No warning light was illuminated. In addition, the contact had to apply extra pressure on the brake pedal to stop the vehicle. The contact stated that there was an abnormal squeaking sound coming from the vehicle. The vehicle was taken to a local dealer, where it was diagnosed; however, no cause for the failure was found. The vehicle was repaired; however, the failure reoccurred. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 7,000.

Apparently many vehicles like mine and including mine have defective radiator hoses or a poor set up with routing causing issues with the hoses. They are developing cracks/leaks causing poor circulation in the cooling system as well as possible engine failure. In speaking to mechanics and reading forum posts, it is evident that this is a large scale issue.

On or about I experienced the check engine light on the above vehicle. After checking, the issue has something to do with the low level in the coolant system. I took the vehicle to a Maguire Chevrolet dealership in Grand Island New York. They charged me $200.00 +tax for diagnosis. They found the Radiator hose was leaking and it isn't covered by the warranty or extended warranty. I took the GMC to another shop for repair. They were told by 3 dealerships the part is on back order and they do not know when it will be in. Just to be sure, I called the GMC Dealership in Rome New York where the VFW purchased the vehicle. I was told they were put of stock but there wasn't an issue. That was on 12/24/2025. the salesman said he would call me on Friday to verify the status of the hose needed. as of 12/29/2025 at 13:00Hrs there hasn't been a call back. My feeling is there must be an issue with the hose in question. The should be a recall and GM should repair the leaking part. [XXX] CFO Departme...
