2024 GMC Acadia

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.

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.

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.

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.
