2024 GMC Acadia: engine failure

Filed Feb 19, 2026 · Engine, Transmission · TX

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.

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 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.

While 2 hours from home driving down the interstate with a full vehicle, the vehicle alarmed and the screen notified "No Oil Pressure, Turn Car Off Now". I pulled over immediately and we had to sit on the edge of the interstate for 45 minutes - a safety hazard for us and the surrounding traffic. The vehicle was towed to the nearest GM dealer, where they assessed the vehicle and advised that this is a known issue for 2024 and 2025 GMC Acadias and Traverses. The vehicle failed to move oil and the engine was seized - a significant safety hazard. After a month, GM has informed us that zero replacement engines are available in the world and there is no timeline for replacement or repair and the vehicle is unusable.

My vehicle is 3 months old with 4650 miles. I was driving on the turnpike and without notice a warning on the dash advised that there was no oil pressure and to pull over. I had the vehicle towed to a dealer out of state since we were 3 hours from home. The dealer called today to advised the car needed a new engine. I asked what was the route cause and they advise the GM did not require the engine to be stripped to find one.
