   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 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.

   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.

    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.
