SERVICE BRAKES
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.

SERVICE BRAKES
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.

SERVICE BRAKES
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.

VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
I'd like to report a safety issue related to the frequency of the adaptive cruise control system on my 2024 GMC Acadia. In multiple instances while traveling at highway speeds (55+ mph), the system will brake heavily when no vehicle or impediment is in visible range. This failure can cause safety issues due to sudden braking at highway speeds potentially leading to traffic accidents and/or fatalities. This failure has happened multiple times, but most recently on 7/21/25, 7/25/25, 10/9/25, 10/21/25, 10/22/25, and 10/23/25. The vehicle was taken a GM dealer on 8/1/25, 8/15/25, and 8/26/25 and they dealership failed to diagnose the problem or indicated all systems were working as intended. The vehicle does not provide any warning lamps, messages, or other symptoms of the problem.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
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.

SERVICE BRAKES
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.

SEATS
No traffic collision. Preemptive report. Headrest positioned so far forward that head is forced into a downward position. Unable to comfortably maintain eye contact with the road in this position (photo attached). Only remedy is to have headrest positioned so far down that it would cause decapitation in a collision. I was not aware of the decapitation risk when purchasing the vehicle. GM initially stated the dealership should have remedies in the form of alternate parts to be installed at the dealership. Dealership stated that is not the case and they do not have any resolution available.

ENGINE
While 2 hours from home driving down the interstate with a full vehicle, the vehicle alarmed and the screen notified "No Oil Pressure, Turn Car Off Now". I pulled over immediately and we had to sit on the edge of the interstate for 45 minutes - a safety hazard for us and the surrounding traffic. The vehicle was towed to the nearest GM dealer, where they assessed the vehicle and advised that this is a known issue for 2024 and 2025 GMC Acadias and Traverses. The vehicle failed to move oil and the engine was seized - a significant safety hazard. After a month, GM has informed us that zero replacement engines are available in the world and there is no timeline for replacement or repair and the vehicle is unusable.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
When backing up and nothing behind car abruptly applies brakes no alerts. This has occurred on multiple occasions and is very scary. This started first week of ownership took to the dealer and was told GM is aware of the issue but no repair available at the time. the car is a year old now and problem is still present I have had to disable the braking feature. The backing emergency braking is a safety feature so pedestrians / children don’t get run over.

EXTERIOR LIGHTING
Rear driver's side brake light/turn signal is out. This is the second time in under a year. Local GMC dealer is not able to replace it within a reasonable amount of time causing a safety issue. This is a well known issue to GMC which is why the part is on back order. No other dealers in my area have the part in stock.

SERVICE BRAKES, ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
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

SERVICE BRAKES, HYDRAULIC, POWER TRAIN, EXTERIOR LIGHTING:TAIL LIGHTS
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.

ENGINE
The Vehicles engine siezed at 6,400 miles leaving us stranded on the side of the freeway for 3 hours and GMC is trying to PIN the blame elsewhere. Car has been in the shop for 3 weeks and they are unsure if it will be covered by warranty. The only thing done to the car was an oil change performed at a GMC dealer.

ENGINE
My vehicle is 3 months old with 4650 miles. I was driving on the turnpike and without notice a warning on the dash advised that there was no oil pressure and to pull over. I had the vehicle towed to a dealer out of state since we were 3 hours from home. The dealer called today to advised the car needed a new engine. I asked what was the route cause and they advise the GM did not require the engine to be stripped to find one.
