2024 GMC Acadia owner complaints

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

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!

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.

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 cylinde

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 fro

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.

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

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.

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 # 9-14086984106) advises me I have

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.

Apparently many vehicles like mine and including mine have defective radiator hoses or a poor set up with routing causing issues with the hoses. They are developing cracks/leaks causing poor circulation in the cooling system as well as possible engine failure. In speaking to mechanics and reading forum posts, it is evident that this is a large scale issue.

On a highway about an hour from home, my brand new vehicle with 5,318 miles on it, alarmed me to turn off the vehicle. I was going 75 mph. I pulled over and called GMC being that I just had an oil change and thought maybe they possibly didn't reset something. The vehicle said the oil pressure was low. The dealership advised me to check the oil. It was full and clean. The service person advised that I should be able to continue to drive. I then called my husband. Upon starting the vehicle it was making a noise coming from underneath the vehicle. He said do not drive that vehicle and he headed to come get me. We had it towed to a nearby dealership around 6 pm. I called GMC again because the tow truck driver could not figure out how to put the vehicle in neutral. The told us to ho

On or about I experienced the check engine light on the above vehicle. After checking, the issue has something to do with the low level in the coolant system. I took the vehicle to a Maguire Chevrolet dealership in Grand Island New York. They charged me $200.00 +tax for diagnosis. They found the Radiator hose was leaking and it isn't covered by the warranty or extended warranty. I took the GMC to another shop for repair. They were told by 3 dealerships the part is on back order and they do not know when it will be in. Just to be sure, I called the GMC Dealership in Rome New York where the VFW purchased the vehicle. I was told they were put of stock but there wasn't an issue. That was on 12/24/2025. the salesman said he would call me on Friday to verify the status of the hose needed. as of

The upper radiator hose, which is part of the vehicle’s engine cooling system, failed prematurely. The component is available for inspection upon request, and documentation of the repair and replacement can also be provided. Failure of the upper radiator hose caused coolant loss, creating a risk of engine overheating and sudden vehicle disablement. This posed/poses a safety risk, particularly if the failure had occurred at highway speeds or in traffic, where an unexpected breakdown could endanger the driver and surrounding vehicles. The issue was confirmed by an authorized GMC dealership, which diagnosed the failed upper radiator hose and performed the replacement. This issue has also been reported by multiple owners of the same model year, indicating a recurring problem. The vehicle and

The super cruise randomly kicks out sometimes in the middle of a lane change and has even kicked out going over a hill and sent the car into the other lane of on coming traffic its has been to the dealer 3 times in the first 3 months of ownership for a total of 18 days in the shop gm says there is no fix at this time. This has happened numerous times

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.

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

I have had 3 taillights replaced. The first one was the driver's side taillight at Marty's GMC in Kingston MA. The second one was the passenger side taillight at Quirk GMC in Braintree, MA and the third one was the driver's side one again. the vehicle had approximately 28,000 miles when the 3rd taillight was replaced and was purchased in August of 2024. Both dealers stated that it was safe to drive the vehicle with the taillights not operating. The first 2 took approximately one week to get the part and the 3rd one took 4 weeks. I believe that this is a serious safety issue as the vehicle tailgate lights are only visible when directly behind the vehicle.

On our drive home from Colorado back to Wyoming. Our 2024 GMC Acadia AT4 had 3,076 miles on the SUV. No problems leading up to this point. Has we crossed the Wyoming boarder emergency light comes off shut vehicle off immediately. Oil pressure low. I pulled over on the side of the road called OnStar for a tow truck. This all took place [XXX] on Sunday. Dealership says the oil pumped failed. GMC needs to issue out a recall for this. I see other people out there deal with the same issue online. It really sucks I put down nice down payment for our family vehicle. Then this happens. We are down a SUV now, I have to pay the taxes on the car $3,239.40 and still making a payment on a car that I can’t drive.
