2024 GMC ACADIA Electrical System Problems

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,...

The contact owns a 2024 GMC Acadia. The contact stated that while driving at an undisclosed speed, the infotainment touch screen failed to display pertinent vehicle safety information. After restarting the vehicle, the vehicle returned to normal functionality, but the failure became a regular occurrence. No warning lights were illuminated. The vehicle was taken to the dealer, who was unable to determine the cause of the failure. The contact was informed that the manufacturer was aware of the issue and was working on providing a fix. The vehicle was not repaired. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 1,000.

I am filing a complaint about my 2024 GMC Acadia AT4, leased brand new from Frank's GMC in August 2024, now with a little over 8,000 miles. The brake pads are worn to 35% life, far below the expected 30,000-70,000 miles, with loud squealing, fluid leakage, and odors. This poses a severe safety risk to my family and others, as compromised brakes could fail. In October 2024, before my 3,000-mile oil change, I reported brake concerns to Frank’s GMC service manager, Javier, who advised waiting. After the November 2024 oil change and tire rotation, only three months after obtaining my vehicle, Javier claimed no issues, despite my prior warnings. The problems worsened, with squealing, leakage, and odors persisting. My March 19, 2025, service appointment was delayed, calls ignored, and follow-ups never occurred. Sales manager Khaled stated that owner Frank confronted Javier about avoiding service issues, yet no action was taken....

This 2024 GMC Acadia will not back up safely on a rainy day. when moving backward, when it raining the emergency braking continually engage, approximately every two feet. I took it to GM dealer service center, it did the same with them. However, they can't correct the problem and GM does not have a fix. Also others vehicle like this one are experiencing the same problem. This has been an ongoing problem since July 5, 2024 in rainy weather. I called GM customer service and have gotten no result. I don't know what to do. can you all help us (Please). Thank you all so very much.

I bought a brand new GMC Acadia at Thompson GMC in Raleigh NC. From day 1 I have been having a issue with the tire pressure sensors disconnecting from the system. Thompson GMC was giving me attitude for bringing it back so many times so I brought it to Leith GMC in Wendell NC for diagnoses. Both shops referred to GM TSB (Technical Service Bulletin) PIT6188 which they both tried the reprogramming with no such luck. I was advised to wait for GM to come up with a fix and refused a loaner for the time unless I paid (GM customer care confirmed I would have to pay up front for a loaner). It is now 6 months later and I am still driving a vehicle where lights still come up on the dashboard and no fix. I get no where with the dealerships and GM customer care (case #...

I was driving and making a left turn at a traffic light when all of a sudden, every light lit up on my dashboard. Then the dashboard turned completely black along with the radio screen. When the dashboard went black, I tried to stop by hitting the brakes to pull over. The brake pedal went all the way to the floor, and I had zero brakes. I was able to coast to a dirt shoulder where the vehicle stopped due to friction and gravity. The brakes never worked to aid in stopping the motion of my vehicle. I had my vehicle towed immediately to the dealership where I bought it.
