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".
The contact owns a 2024 GMC Acadia. The contact stated that while driving at an undisclosed speed and depressing the brake pedal, the brakes made an abnormal squealing sound. Additionally, brake pad dust was frequently visible on the rims. The dealer was contacted and advised that the brake issue was caused by driving through a car wash. The vehicle was not repaired. The manufacturer was not notified of the issue. The failure mileage was 25,312.
Front left brake was locking up. Happened 1st a couple months ago. Happened again recently and was towed to dealership. Burning smell from brake and hot in wheel area. Left front brake caliper was locked, pads overheated, rotor warped. Replaced front left caliper, front left brake hose, front pads, and front left rotor. Road tested, brakes operate properly. Brake life on monitor shows 18%, brake pads are at 8mm out of calibration, reprogrammed brake system control module and performed brake percent calibration per bulletin #25-na-282. Warranty code is 28yz314171448.
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 am submitting a complaint regarding premature front brake wear on my 2024 GMC Acadia. At approximately 16,000 miles, sewell Buick GMC of midland inspected my vehicle and measured the front brake pads at 5 mm. Despite the pads not being at the replacement threshold and the vehicle being safe to drive, the dealer is already recommending brake replacement. The dealer also advised that the brake parts are currently on backorder due to the high volume of repairs needed for the same issue with no estimated time of arrival. I am concerned that requiring brake replacement at such low mileage indicates a potential design, material, or manufacturing issue with the braking system on this model year. I am also concerned about the lack of parts availability should brake wear progress more quickly than expected. The vehicle is driven under normal conditions (no towing, no aggressive driving), and routine maintenance has been followed. Given the low mileage and early wear measurement, this is abnormal for a new vehicle. I am submitting this complaint so NHTSA can track similar reports and determine whether further review or investigation is warranted. Thank you for your attention to this matter. Sincerely, olivia garcia.
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!!.
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.
The vehicle brake system completely failed. The brake pedal was depressed and several warning lights were illuminated on the dash, yet the vehicle would not come to a complete stop. At the time of failure, the abs light, parking brake light, traction control light, and collision light illuminated on the driver display. Additionally, the dash displayed a message requesting the driver to depress brake pedal hard and to “service esc”. The brake pedal felt soft and would go all the way towards the floor. The vehicle had very limited braking and would not come to a complete stop. The vehicle was taken to a gm dealership for diagnosis and repair. The dealership confirmed that the brake system had failed and there was inadequate stopping force being produced. The entire master cylinder assembly which includes the hydraulic valve block and electric motor were replaced under warranty. The vehicle had 24,638 miles at the time of failure. Prior to the failure, there were zero indications that there were any issues with the brake system. Fortunately when the brake system failed the vehicle had just backed away from a parking spot and pulled forward towards a stop sign at low speed. The potential concern was that pedestrians, fellow motorists or the driver of the vehicle could have experienced significant injury or death due to the vehicle’s brakes failing.
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.
When backing up brakes abruptly apply themselves for no reason at all. This happens all the time the dealer says there is no problem with my vehicle, but the rear breaking abruptly keeps on applying.
1. The electrical system and driver-assistance/safety features malfunctioned, including intermittent power loss and dashboard system failures. The vehicle is available for inspection upon request. 2. The malfunction caused the vehicle to lose power to the braking system while driving, which created a risk of collision. Essential safety features such as power steering, brakes, and warning systems were impacted, putting both myself and other drivers at risk. 3. Yes. The issue has been reproduced and documented by the dealership during multiple service visits and reported to gm customer service. However, the safety claim was denied by gm and I have been advised to continue to drive this unsafe vehicle. 4. The vehicle has been inspected by the authorized dealership and GMC technicians. It has not been inspected by police or insurance representatives at this time. 5. Yes. Warning messages appeared on the dashboard, including system errors and power failure alerts. These issues first appeared around 20,000 miles, and have recurred intermittently since then. I have communicated with the dealership where the car was purchased and gm corporate requesting replacement with a safe and reliable vehicle. To date, I have not received a satisfactory resolution. I have researched and found that other 2024–2025 GMC Acadia owners are experiencing the same issue. This vehicle is unsafe to operate until gm identifies and resolves the defect. Losing control of the brakes constitutes a catastrophic safety failure that makes this vehicle unfit for road use. Immediate investigation and corrective action are necessary to prevent potential accidents or injuries.
Brake sensor warning pops up that says brake pads need to be serviced. Brake pads still have between 80-92% wear left according to the dealership. There is a TSB out for this issue (#n242471431) but GMC refuses to repair at no cost. States that even though my vehicle is within the parameters of the TSB, it is VIN specific.
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.
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?.
When pressing brakes to start the car the pedal goes all the way to the floor with little or no resistance. It has happened three times in 3 months. Took it to gm dealer after the first two incidents and they did a software update. Took it in again after the third incident and they did nothing.
When the vehicle is in reverse and you are backing the emergency brake suddenly comes on practically giving you whiplash. This happens randomly and without any obstruction or reason for the emergency brake to come on. It has happened many times. This morning it slammed the emergency brake on 4 times in a row I didn't think I was going to be able to back up as it kept kicking the emergency brake on. Based on what I have seen on the internet many 2024 GMC Acadia owners are having similar problems. Gm needs to fix this!.
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.
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.
The contact owns a 2024 GMC Acadia. The contact stated there was an abnormal squeaking sound coming from the vehicle while depressing the brake pedal. There was no warning light illuminated. The vehicle was taken to a dealer and the brake pads were replaced; however, the failure returned several days later after the repair. In addition, the contact stated that transmission fluid was leaking from the vehicle. The contact also stated that both taillights had failed to operate as needed and the message "check left rear turn lamp" and "check right rear turn lamp" messages were displayed a day apart. The vehicle was taken back to the dealer where the mechanic confirmed that there was a transmission fluid leak due to defective bolts. The dealer also replaced the rear taillights. The contact was also informed that there were no issues with the brakes, even though there was a noise coming from the vehicle. The manufacturer was not notified of the failure. The vehicle was not repaired and remained with the dealer. The failure mileage was approximately 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. 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 NHTSA 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.
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.
