On September 26th, 2026 I got a random notification about needing to get my rear left turn signal checked out as it still functions but blinks rapidly. Today, September 28th, 2026, I visited my local dealership for the issue and was informed that they had received a bulletin regarding the concern but that instead of covering the defect tied to a "software anomaly", I was told it would be around $600 to replace. I feel this is a strong enough safety issue that should be considered for a recall as this is a widespread problem and should be covered by GM.

Well, let’s try this again. The first try disappeared. The rear hatch seal on the vehicle has identical spots on both sides of the hatch that are mashed flat. I think this is being caused by the flat spots on the hatch itself. The vehicle is a total body and engine redesign. The flat spots allow…
Well, let’s try this again. The first try disappeared. The rear hatch seal on the vehicle has identical spots on both sides of the hatch that are mashed flat. I think this is being caused by the flat spots on the hatch itself. The vehicle is a total body and engine redesign. The flat spots allow for dust intrusion into the cabin all the way to the front of the cabin. We live on a gravel road, so we can see the intrusion, albeit it took a while to figure out where it was coming from. People in town won’t know. I videoed the seal and hatch the day before it was replaced by the dealership. My fear is that someone on a trip may get into trouble, because you know if dust can get in, carbon monoxide can as well. I’ll include the video. Thank you for reading.

Today, on [XXX] outside of Sapulpa Oklahoma, while in the inside lane of three southbound lanes, cruise control on at 80mph. The car suddenly reduced power, air conditioning stopped, assisted power brakes stopped working, gauge cluster full of flashing warnings. Pulled to the right shoulder, stopped with difficulty. Had to pump and stand on brakes to get stopped. Shut off engine, then restated and everything stated working again. Scary situation in heavy traffic. Lucky to be alive!!

When backing into my driveway the brakes failed. I was nosing the car across the street towards the neighbors driveway so I could put the car in reverse and back it into the driveway. I applied the brakes while traveling at about 3-4mph when the brakes had little resistance and went straight to the floor and the vehicle continued moving forward. Attempted to apply brakes again and the same result. Ended up hitting the neighbors parked car in their driveway. Luckily it was a very low rate of speed so there was minimal damage and nobody was hurt. There were no warning lights present before, during, or after the incident. The vehicle got towed to a local GMC dealership who could not replicate the issue. Insurance is still looking into the issue.

The contact owns a 2024 GMC Acadia. The contact stated that after an oil change, while starting the vehicle, the steering wheel became inoperable. The contact became aware that the top of the steering wheel was cracked and had popped out of place. The contact stated that while driving, the failure caused a cut on the hand. The vehicle was taken to the dealer, where the failure was confirmed. The contact was informed that the steering wheel needed to be replaced. The dealer referred the contact to the manufacturer for assistance, and a case was opened. The contact believed the failure might be related to the leather on the steering wheel, which had deteriorated due the changes in the weather. The contact was concerned that the damaged steering wheel posed a safety risk while operating the vehicle. The failure mileage was approximately 47,000
- Seat belts
2024 GMC Acadia grounded at dealership for 3+ weeks due to unavailable driver seat belt buckle (Part 26522477), rendering a brand-new vehicle legally un-driveable due to primary restraint part constraints. The buckle will not latch, causing the seat belt to be rendered inoperable. The problem was reproduced by the dealership, and the replacement part is backordered.

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".

I purchased this vehicle in June 2024 as a demo vehicle with approximately 7,000 miles on it. Within one month of ownership, the vehicle began experiencing serious problems that have continued to worsen. The vehicle currently has approximately 34,000 miles, and the issues have been ongoing from the time of purchase through the present. Since purchasing the vehicle, it has been in the dealership multiple times for the same recurring problems, including but not limited to: * Powertrain issues and loss of power * Reduced acceleration while driving * Complete electrical failure while driving * Engine and electrical warning lights repeatedly turning on * Vehicle running excessively hot * Water pump replacement * Replacement of sensors * Thermostat replacement * Ongoing engine and electrical system malfunctions Despite these repairs, the same problems continue to reoccur. Each time I return the vehicle for service, I am informed that it is a “different issue,” even though the symptoms remain unchanged. This strongly indicates a defective powertrain and/or electrical system that has not been properly repaired. The most serious concern occurred while I was driving on public streets, when the vehicle lost acceleration, electrical power shut off, and the vehicle completely shut down, nearly causing me to be hit by other vehicles. This incident created an extreme safety hazard for myself, my passengers, and other motorists. I have made several formal complaints directly with GMC, and more than four case numbers have already been created regarding this vehicle. Despite these complaints and repeated repair attempts, the problems persist. Given the repeated failures, numerous repair attempts, documented safety risks, and the fact that these issues began shortly after purchase, I believe this vehicle qualifies for relief under applicable lemon laws and consumer protection laws.

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 the vehicle to have a safe way to get our kids around and it has been nothing but a headache and run around from the dealership. GMC really needs to resolve this issue. Parts seem to be on never-ending backorder with no ETA.

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?

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 is on nationwide back order. GM admitted to a faulty design, in the process of redesign. A SPAC case with a local GM dealership was opened. GM would expedite my case if I towed to a GM dealer. I would have to pay for the tow. And just how can my case be expedited if the part isn't available? It can't. I was told the redesigned hose is going on the new models currently being built. I have lost all faith in GM. Today is February 19th and my car is still at the mechanic with no ETA on part delivery. I called every GM dealership parts department within 100 miles and get the same response, "we have two hoses with four cars needing it, we have 4 hoses with 8 cars needing it, the hose is hell to find, etc.". Why has GM not issued a recall on the upper radiator hose. If you have a 2024 GMC Acadia, you will incur this same 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!!

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 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 12/29/2025 at 13:00Hrs there hasn't been a call back. My feeling is there must be an issue with the hose in question. The should be a recall and GM should repair the leaking part. [XXX] CFO Department of New York VFW.

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.

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 failed component were inspected by an authorized GMC dealership. No inspection by police or insurance representatives was required, as this was a mechanical failure and not the result of an accident. Prior to the failure, symptoms included coolant loss and cooling system concerns, which ultimately required dealership diagnosis. Any warning indicators appeared shortly before the issue was identified, with little to no advance warning before the component required replacement.

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 hold the start button down but do not push the brake. That didn't work. The tow truck driver put plastic slides under the back tires and dragged it onto the tow truck bed. The service center was closed so we were unable to speak to anyone. Days later we were told the engine seized. It took 3 guys to get into the bay. GMC advised the dealership service to take apart the engine in order to investigate the failure. They did and established it was a bearing. It was in the shop for 52 days. I was told the replaced engine was a remanufactured engine by GMC and by the service center more than once. I was very angry. I bought a new vehicle, not a used one. Then I was told it was a new engine. Since I purchased this vehicle I feel like there have been soft truths. I'm not sure what to believe. Upon picking up my repaired vehicle there was not a drop of gas in it and 77 miles added to the mileage. I get that the vehicle needs to be test driven but that seems like a lot. I think new engine, new odometer starting at 0? I bought a new vehicle for safety. I have a 2006 GMC Yukon that has been very reliable which is why we purchased the Acadia. I seriously do not feel safe.

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.

On April 11, 2024, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE24011 after receiving complaints concerning a loss of brake assist in 2023 MY Cadillac Lyriq vehicles. These complaints allege a hard brake pedal, followed by a “Brake System Failure” message at start up or while driving. GM shared records regarding several internal investigations for loss of brake assist due to alleged spindle fractures in the eBoost system. GM has stated that in the event of a spindle fracture, anti-lock brakes (ABS), stability control, and traction control remain functional until the vehicle comes to a complete stop. At this point, ABS, brake assist, stability control, and traction control functions are lost. The loss of these functions causes the vehicle to set one of three Diagnostic Trouble Codes (DTCs) based on failed performance criteria for the Electronic Brake Control Module (EBCM). These DTCs, in turn, activate several driver alerts: an audible chime, a visual “Service Brake System” message in the display, and multiple illuminated Malfunction Indicator Lights (MILs) for the ABS, Traction Control, and Brakes informing the driver of loss of functionality. The vehicle speed will also be limited to 70 KPH (43 MPH). Since opening PE24011, ODI has continued to receive reports of loss of brake assist. Some of these reports describe symptoms inconsistent with GM’s description of a spindle failure. These reports allege an immediate loss of brake assist functionality as opposed to the loss occurring after the vehicle comes to a complete stop. The sudden loss of brake assist during a braking event could result in extended braking distance, which increases the risk of a crash or injury. ODI believes further analysis is necessary to assess the potential for failures in GM’s eBoost system to resulting in safety-related outcomes. At this time, ODI is aware of the following vehicles that are equipped with this eBoost system: 2023-2026 MY Cadillac Lyriq, Chevrolet Colorado, and GMC Canyon; 2024-2026 MY Buick Enclave, Envision; Chevrolet Blazer EV, Equinox EV, Traverse; Cruise Origin; and GMC Acadia; 2025-2026 MY Cadillac Celestiq and Optiq. ODI is also aware of 2024-2026 MY Acura ZDX and 2024-2026 MY Honda Prologue vehicles that were built with this system. The Acura and Honda vehicles were manufactured by GM in a joint venture with Honda, and will be included in the Engineering Analysis as peer vehicles. ODI is opening this Engineering Analysis to further assess the safety-related consequences of a failed eBoost system. In addition, ODI is expanding the scope of the investigation to encompass all GM vehicles that share this eBoost system. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.
