2024 GMC Acadia: grinding or squealing brakes

Filed Jun 22, 2026 · Brakes · TX

At low speeds the brakes squeal horrendously. We have taken the vehicle to the dealer multiple times and each time they state that the brakes are fine. A vehicle with this low of miles should not have squealing brakes since new.

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".

Brakes have been squealing since 6500 miles. The dealer resurfaced the rotors and cleaned the pads only for the brakes to be squealing again. The dealer has cleaned the brakes and applied "squeak stop" only for the brakes to continue to squeal. The service guide from GM says if brakes are making any noises they need to be "inspected immediately" however I'm being told there's nothing further to be done. How do I know if the squealing (which is truly happening every time I drive the vehicle) is normal or if there's a larger and more concerning issue?

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 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 have experienced multiple recurring issues with our 2024 GMC Acadia that raise significant safety concerns and affect the vehicle’s reliability and overall operation. First, the brake system exhibits persistent squeaking, even at low speeds or light applications. The dealership has inspected the brakes but the noise continues, raising concerns about premature wear or improper brake function. More concerning is the behavior of the automatic braking system while reversing. The system has repeatedly activated the brakes without any obstacle, vehicle, or person behind us. These unexpected braking events have created both physical and psychological stress for occupants and pose a real risk of causing a rear-end collision from another driver who may not anticipate sudden braking. Due to this hazardous condition, we have been forced to deactivate the automatic braking feature entirely, defeating a critical safety system the vehicle is equipped with. Additionally, the engine frequently runs rough during cold start and the initial warm-up period for the first couple of minutes. This rough operation is inconsistent with expected behavior for a new vehicle and has not been fully resolved despite service visits. The TPMS sensors have also been problematic. Several sensors have already been replaced by the dealership, yet we continue to experience intermittent TPMS faults involving at least two wheels. This results in repeated warnings, loss of real-time tire data, and uncertainty about actual tire pressure conditions while driving. We also experience rattling noises from the interior trim near the door seals whenever there is a cross breeze or windy driving conditions. This appears to be a structural or insulation-related issue. We have others, but this space only allows for 2000 characters, and after writing this sentence, there are only 113 characters remaining.

Breaks are squeaking awful. Have had front brakes and rotors replaced which cost $380. Did not fix the problem. Have also saw where a lot of other 2024 gmc Acadia owners are experiencing the same problem.

Since we purchased this vehicle, we have continually had issues with our brakes to include dragging of the front brakes and brakes squealing when they are in use. We have brought the vehicle multiple times to the GMC dealership who is able to replicate the issue, but states that this is normal. I have filed a complaint with the GMC and they said that this is normal even though they admitted to fixing the problem in 2025 models. Per GMC, they will not be stand behind their product unless the national traffic safety issue administration tells them they need to. This is very frustrating as if you do a search online you will find many other consumers with the same vehicle and same issue with no resolution, this is a safety concern that the brakes are not functioning properly as well as the front brakes also caused an issue with a sensor in my car. They fixed the sensor are unable to fix the front brake issue Due to no recalls or issues given to them by the national traffic safety. GMC will not make any fixes as they consider this normal.

My vehicle only has 12,000 miles and it’s a 2024 and the brakes are constantly squeaking. I’ve reported this multiple times at my dealership and they are stating “this is normal and because of the new heavier materials there is not a fix for this.” I’m really concerned about this as it’s a safety issue. This car is also too new to be having this type of issue. I’m also apart of a owners forum and several owners are having the same issue. For the report today I’m putting the most recent date but as stated I have reported this several times with my local dealership Group 1 GMC here in Houston, Texas.

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. I contacted ten GMC service departments in PA, CT, and MD; they reported similar AT4 brake issues, some citing total brake failure. I spoke with GM corporate supervisors, who referred me back to the dealer. Frank’s GMC inspections overlooked my concerns. A local police department safety inspection unit confirmed the issues, but no manufacturer or insurance inspections occurred. The vehicle is available for inspection. I urge the federal safety agency to investigate this premature brake failure and ensure the 2024 Acadia AT4’s safety. The email screenshot I included was sent in April. I contacted the same GMC dealerships that previously reported no issues to check for updates, and they confirmed a change. All of them now report the same problem with brake pads and/or brake failure. This issue is covered under warranty and should be replaced without issue, but dealers are not complying. If overlooked, this could become a national concern
