ENGINE
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.

SERVICE BRAKES, ENGINE, WHEELS
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.

The antenna fin cover came off while driving down the road. I had been a possession of the car less than six weeks. I’ve contacted the dealership- it’s covered under warranty, but the part is backordered because it’s such an issue.

I accidentally ran out of gas and my car died directly underneath a railroad crossing arm. I had been stopped to allow an Amtrak train to go by and my car died when I started to move forward after it passed. Thankfully I wasn't on the tracks, but I was close to them. I immediately got out of my car and the woman behind me said she would help push me out of the way of the crossing arm. I went to put my car in neutral, something I do weekly when I go through the car wash, but my dash kept saying "conditions not correct for shift". I tried repeatedly and it would not allow me to put the car in neutral because I couldn't fully turn it on. I did a quick search online and found there was no information on how to get it into neutral if the car is dead. My battery was still working and my car was in accessory while I was trying to change gears. I had to call 911 and they had to reach out to BNSF to alert incoming trains. It was an ordeal. I spotted a tree removal company across the street and they had a can of gas for me to use. I was able to partially fill my tank and then drive across the tracks before a train came. Afterwards I called the dealer and we discovered together that there is no backup safety feature that allows a disabled car to be put into neutral. The dealer was just as surprised as me. This seems like an obvious safety issue if a car is to break down on train tracks, the middle of the freeway, or in an intersection. I don't understand why it is allowed and why dealerships and the public are seemingly unaware of it.

The rear view camera fails to function intermittently and is occurring at a higher rate of frequency. On numerous occasions when the vehicle is put in reverse the screen goes black with a red triangle caution symbol and a white camera crossed out. Now the system is unavailable more then operational. Based on the drivers rear vision when backing in this particular vehicle, the lack of the rear camera view increases the risk of crash. This also increases the risk of severe injury to a pedestrian behind the vehicle. The same issues were addressed on earlier models via a safety recall which should be extended to 2023 model.

EXTERIOR LIGHTING
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. Both dealers stated that it was safe to drive the vehicle with the taillights not operating. The first 2 took approximately one week to get the part and the 3rd one took 4 weeks. I believe that this is a serious safety issue as the vehicle tailgate lights are only visible when directly behind the vehicle.

Coolant temperature gauge stops working and shows cold temperature reading. The radiator fan runs for about 2 minutes as if the engine is overheating. I think it's a temperature sensor issue or thermostat issue or both.

Multiple times an alert has been given for "Driver assist temporarily reduced, drive cautiously". Additionally, the check engine light has come on, with codes for the cooling system. Cooling system fan (HVAC Blower) remains on after shutting off vehicle for anywhere from 5-15 minutes. Coolant levels have been checked and are correct. Heat & AC function, however the thermostat gauge on the instrument panel does not read any temperature at all. At this time, the vehicle has not been taken to the dealership for assessment due to financial constraints.

The driver was able to coast to the shoulder of the roadway, where the vehicle failed to restart. The check engine warning light was illuminated. The vehicle was towed to an independent mechanic, who diagnosed a failure with the fuel pump control module. The vehicle was repaired. The manufacturer was notified of the failure but provided no assistance. The failure mileage was 36,970.

GM need to be looked at for faulty Thermostats being put into vehicles. While driving the message "steering assist is reduced " You get to a safe place and shut you car off and the fan still runs. After speaking with my dealer today, he said he has done 7 in last week. And if you look online, everyone especially Acadia models is having this problem. Customers are getting charged alot of money for the repair. To me this is a defective thermostat on GM and needs to be addressed
