“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 brak…”

Forward Collision Avoidance 10

“I'd like to report a safety issue related to the frequency of the adaptive cruise control system on my 2024 GMC Acadia.

“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…”

“In the process of taking my daughter to the emergency room I receive a dash notification on my recently purchased 2024 GMC Acadia "car overheating, possible engine failure". My gauges were within normal range and being that I was in an emergency I kept traveling. Leave hospital to head home the error message is gone. The following Monday, January 5th, heading in to work I receive the same error message on my dash "car overheating, possible engine failure". Drove to the nearest mechanic, left my car, and they discover a leak in the upper radiator hose. They call with bad news that the part…”

“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…”

“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.

I believe that this is a serious safety issue as the vehicle tail…”

“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.”

Seats 3

“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.”
NHTSA complaint #11686746, 2025

“GMC told me I needed to contact you regarding my third row seats not going down flat. The headrest will not flip forward causing me not to be able to use my vehicle as intended.”

NHTSA complaint #11740702, 2026

“The automatic braking system activates when there is no danger of collision or impact. During heavy rain, backing out of a parking space, with no hazard activating the emergency braking system near your vehicle, the emergency braking system will activate every 2-3 feet driven- sometimes occurring 6-8 times when trying to back out of space. This is a safety hazard because you’re left sitting in a roadway with no control over vehicle. Your chances of being hit by oncoming traffic, because your vehicle stops itself over and over, is high. Not only is the automatic braking jarring, you have to sit…”

Unknown Or Other 2

“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…”

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, whi…”

Wheels 2

“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 braki…”

“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…”

Suspension 1

“2024 brand new Acadia Denali trim with 1k miles was brought in to the dealership because of 'popping' and 'grinding' noise when turning, most loudest when turning to and from the right. It was also very much felt on the steering wheel. Dealer took apart the front right strut assembly and said that it was not 'installed' properly, causing the springs to hit the fender everytime the wheels turned. They inspected it said that nothing needed to be replaced, installed it properly, test drove it and determined that it was fixed. Driving home, I sped through potholes and bumps, especially during tu…”
