2024 GMC Acadia problems

“When backing into my driveway the brakes failed. I was nosing the car across the street towards the neighbors driveway so I could put the car in reverse and back it into the driveway. I applied the brakes while traveling at about 3-4mph when the brakes had little resistance and went straight to the floor and the vehicle continued moving forward. Attempted to apply brakes again and the same result. Ended up hitting the neighbors parked car in their driveway. Luckily it was a very low rate of speed so there was minimal damage and nobody was hurt. There were no warning lights present before, during, or after the incident. The vehicle got towed to a local GMC dealership who could not replicate the issue. Insurance is still looking into the issue.”

“Today, on [XXX] outside of Sapulpa Oklahoma, while in the inside lane of three southbound lanes, cruise control on at 80mph. The car suddenly reduced power, air conditioning stopped, assisted power brakes stopped working, gauge cluster full of flashing warnings. Pulled to the right shoulder, stopped with difficulty. Had to pump and stand on brakes to get stopped. Shut off engine, then restated and everything stated working again. Scary situation in heavy traffic. Lucky to be alive!!”

“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…”

“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 have ended very badly for myself and/or others. There are several other reports of this nature. Please look into recalling this vehicle to prevent fatalities!!”

“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.”

“On September 26th, 2026 I got a random notification about needing to get my rear left turn signal checked out as it still functions but blinks rapidly. Today, September 28th, 2026, I visited my local dealership for the issue and was informed that they had received a bulletin regarding the concern but that instead of covering the defect tied to a "software anomaly", I was told it would be around $600 to replace. I feel this is a strong enough safety issue that should be considered for a recall as this is a widespread problem and should be covered by GM.”
