Won't shift into park alert came on. Vehicle wouldn't shift into park. Danger of vehicle roll off? Took to GM dealer who replaced GM part 13545094 transmission controller aka shifter assembly. It is believed this defect was detected and recalled on 2018 GMC Acadia models. My 2019 was made in 2018. In service date 10/04/18.

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.

Shift to Park Issue - this is a know issue/recall for the 2019 GMC acadia yet it when I enter my VIN number the recall doesn't show up as a problem. YET it took me 10 tries yesterday to try and turn my car off because each time I went to turn it off, I got the message to Shift it to Park. This has been occurring weekly since I purchased the used car in August 2025.

I have been having issues with shift to park message for a yr now and it just gets worse and do not have the funds to pay for it myself bu5 see that it is a recall and gm is covering cost for other makes models of my same yr for same issue takes sometimes 20 minutes to mess with my shifter until I can finally park my car where it shuts completely off. This is a safety risk as 1 it could roll away if it isn't 2 my car could drain and die leaving me stranded by not turning off fully one time. This is ridiculous I called gm and all they just pushed me off I don't understand how this is not being taken serious especially knowing this is a known problem!

Shift to park message has appeared again and the engine will not cut off. First happened in Feb 2020, mileage was 31,143. Took to Dealer and new wiring harness was installed. Had to take back to dealer April 2020 for same problem; shifter assembly was replaced at that time. Shift to park message came back on August 2023. Took back to Dealer and shifter harness replaced again and jumper harness was installed. Mileage was 52,993. Shift to park message has once again appeared, December 2025. Having to put car in park and push engine on/off button numerous times before engine will finally shut off.....sometimes having to unhook battery in order to kill the engine. This will be the fourth time we have had the same recurring issue repaired. My husband read through over half the 352 registered complaints and at least three fourths of them were all about the SHIFT TO PARK problem! As a female, I don't feel safe driving my Acadia not knowing if the engine will cut off or if it's actually in park or if the car will roll. Why can't GM fix this issue!!!!!! They should definitely be held accountable instead of ignoring the complaints!

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.

There are 2 issues im experiencing. The first is the vehicle won't allow me to shut down the engine because it doesnt recognize that its been shifted into "park". Ive already paid close to 800.00 to.have this repaired because my model year is not covered in the recall. Today, it started doing it again. The safety issue is that either I, my wife, or my teenage daughter (depending on who is with the vehicle). Can be left stranded, unless we pop the hood and disconnect the battery. The second issue is that the tire pressure monitor is no longer working. It is sending warnings that our tire pressure is low. When its not. The safety issue is needing to pull to the side of the road to check the tire pressure and also not knowing when the vehicle may actually have a low tire.

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.

The contact owns a 2018 GMC Acadia. The contact stated that after shifting to the park(P), there was an audible warning alarm activated, and the message "Shift to Park" was displayed, and the vehicle failed to immediately turn off. After restarting the vehicle and jiggling the gear shifter, the failure was corrected. The vehicle was taken to the local dealer, who diagnosed the vehicle and determined that the gear shifter assembly was faulty and needed to be replaced. The vehicle was repaired, but while picking up her daughter from school, the gear shifter was shifted into park(P), and moments later, the vehicle started rolling backwards. The contact had to activate the parking brake to stop the vehicle. The vehicle was later towed back to the dealer. The cause of the failure was not yet determined. The manufacturer was not notified of the failures. The failure mileage was 120,000.

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.

The car is in park & ignition button has been hit to turn vehicle off. When engine is turned off all interior, exterior, dash, & ignition switch lights remain on with a notification on the dashboard stating to "shift to park". The doors can not be locked when this message is on the screen. It can take anywhere from 30 seconds to 15 minutes for the lights & dash to go out, allowing you to exit & lock the car. If you exit the car while the message still appears on the dash, not only are the lights on & unable to lock the car, but if someone where to get into the car, without the key fob, they can start the car & drive off. My husband & I were in a shopping center parking lot in July 2025 where the "shift to park" error came on. We sat in the car, 110 degrees outside, for 10 minutes waiting for the car to shut down. Finally we had to exit the car because we could no longer take the heat. My husband went back to the car, 5 minutes late, while I was in the store to see if the car had finally shut down. To his surprise the lights and dash where still on. He noticed the start button light was also still on & thought if he hit the button the lights would shut off, but no, the car actually started & again he did not have the key fob with him. This is a serious issue & needs to be addressed & I do not feel that I should be paying for this repair. My husband unexpectantly passed away in Sept 2025 & now I am left to deal with this on my own. I have to get this issue fixed as I can not take the chance someone will take my car someday nor do I want to continue to sit in my car for 10-20 minutes waiting for it to shut down. The dealership I took it to diagnosed it as due to a faulty switch in the shifter which means its poor workmanship & not related to owner usage. Please add this to the recall list so that I can get it fixed quickly or if I have to get it fixed prior to being approved by you I can at least recoup my money. Thank you

There is a "shift to park" alert that is listed as a recall from 2017-2019 gmc Acadia's. I have this alarm but apparently my vin is not affected. I would like this to be investigated as it seems my vehicle should be included in the recall.

After I put my car in park my daughter and I were still in the vehicle for a few minutes getting our things with the engine still running. I got out to get something from the back seat, my daughter got out the passenger door and made it to the driver side as I was closing the back passenger door. I was about to get back on the car to get the rest of my things and turn the ignition off but before I could my car was rolling backwards out of the driveway into the street. I was able to jump in the vehicle and put my foot on the brake and the put the gear into Park. There’s no way possible I didn’t put it in Park with me getting out already and my daughter couldn’t have accidentally shift the gear because she couldn’t have been able to get out, close the door and make it to the driver side before it started rolling away. Once I got the car stopped, I noticed the driver seat was now all the way to the steering wheel and completely to the floor with the headrest also tilting inwards and now the electrical for the seat will not work. There is a recall for this issue but my vin# is not included. I cannot even drive my car now because the seat is so far up and inclined. what if the seat moves up more while I’m driving and it has me pinned between the steering wheel and the seat. I don’t feel safe driving it, having my daughter as a passenger and it’s really not safe to be on the road. I’m still paying on this car and now i won’t even be able to drive to work. So I’ll probably lose my job. This car has multiple issues and I think is an electrical problem. It’s also a known major defect on this model but still not a recall for my vin #! None of my interior sound works. Speakers, blinkers, alerts, back up camera. The auto start won’t start, I have to press the key fob multiple times to lock and unlock. This car is extremely unsafe to drive and I strongly feel my cars vin# should be listed under the recall. Its going to really affect my daily life and means of income. Lemon!
