general problems of the 2019 GMC Acadia - part 2

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.

On my 2019 Acadia, the message shift to park keeps appearing on my dash when I shirt the car into parked. It's getting more frequent and when I called GMC it's a well known problem to where the lady taking my appointment says yes we are aware it's happening alot. They want to charge 800 to fix a problem that should be a recall. It's a well known problem and there has been cases and suits brought up and GMC will not make a recall on this even though the mechanic said I can't believe this hasn't been recalled. Can you help with making GMC do a recall in the shift to park. Thank you.

Whenever parking the car and trying to stop (shut off) the engine it will randomly say “shift to park” and I cannot shut the vehicle off.

We receive a shift to park message when we try to turn our 2019 GMC Acadia off. The vehicle is already in park, but an alarm bell keeps going off telling us it is not. The vehicle will not allow us to shut off the vehicle properly and results in battery drain and inability to lock the vehicle. We have noticed there is a class action lawsuit and recalls from previous year's models and the 2019 model manufactured in ohio, but ours was manufactured in tennessee. Our year, make, and model isn't listed in the class action lawsuit and/or a recall. This is very frustrating considering the number of similar issues/complaints in regards to this shift to park problem. I feel GMC as the manufacturer should be held liable for a faulty part and they have failed to correct this issue in later models since they were aware of the issue with the 2017-2018 Acadia models built in tennessee.

When I turn the ignition off it sends me a message that I must shift to park. The car is in park at that time that I get the message. I restart the car and move the shift to reverse or drive and move the car and place in park and that may correct the problem or I may have to do this once, twice even three times before it corrects. The warning bell will continue to ring and the radio continues to play until I can get the situation corrected.

Shift to park error message consistently displayed forcing repeated restarting of the vehicle so that it finally recognized that the vehicle was in park and would unlock the doors for safe exit from the vehicle. This was a known issue by general motors and they have 2 class action lawsuits filed n the states of ohio and tennessee for this issue with well over 110,000 vehicles affected. General motors refuses to acknowledge this defect and fails to issue a recall. Their only offer when I took this vehicle to a gm certified dealership was to offer 15% towards the replacement of the shifter assembly. The excuses made were the vehicle was out of warranty as well as over in mileage. I bought this vehicle used from an Acura dealership and accepted delivery of it on [xxx] with approximately 33,417 miles. I started to experience the shift to park error message at 36,013 miles in early may 2025. By the time I was able to receive instructions from GMC customer care and secure repair for this issue the vehicle mileage was approximately 37,000 miles. It is not a pleasant feeling to be trapped inside your vehicle until you can get it to finally recognize that the vehicle truly is in the park mode. With the hundreds of thousands of vehicles on the road with this issue I feel gm should recognize their problem and perform a vehicle recall. This flaw had been installed in numerous gm vehicles manufactured as early as 2017. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Yes, my vehicle is available for inspection upon request. When I go to put my 2019 GMC Acadia in "park" the shifter states it is in park & the dashboard shows it in "p. " however, when I turn the vehicle off, an error message comes up reading "shift to park" and my car wont fully shut off. You can feel the car move forward or backwards a tiny bit (depending where vehicle is parked). This makes me have to turn the vehicle back on, shift into "drive," back into "park," and then shut the engine off and pray the "shift to park" display doesn't come up. This process was repeated this morning when I arrived at walmart 3x before it finally shut off, then when I got home it happened at least 8x before I could safely leave my car in my garage without the worry of it not truly being in park. This has gotten to the point I have bought wheel chalks to put around my car tires because I am afraid this vehicle could roll down my driveway into my neighbor's house or kill some kid playing in our culdesac. I let the last place I was at know & they told me GMC was aware of the issue, but that there was no way to fix it (auto revival in justin, TX). I am unsure as to whether this issue happened for them or not, as nothing was mentioned after being told GMC is aware. That was on January 10th, 2024. No one else has looked at it besides that. It seemed to be occurring less frequently for several months, and then now it is the worst it has ever been.

This happens sporadically and can take up to 15 minutes to get vehicle in the right position to completely park and shut off.

My 2019 GMC Acadia with 33,000 miles on it started to give me a notification to "shift to park" even though I had already shifted the vehicle into park. A "ding! ding! ding!" alarm wouldn't go off and the vehicle wouldn't turn off unless I repeatedly changed the gears until it read it was in park. This went on for a few weeks and got progressively worse. I read on a GMC forum that the vehicle could slip out of gear while driving and potentially cause an accident. My mechanic found the shifter assembly to be defective and replaced the entire gearshift lever assembly. He said there was a plastic piece in the gearshift that snapped off and said this was an issue in the older models but thought GMC had fixed this issue by 2019.

I do not have current recall on my vehicle, but my vehicle is experiencing the "shift to park" issue that many of the same year make and model mine is experiencing. I am unsure why my vehicle would not have one. It is messing up the transmission and I have only had this vehicle for a year from a dealership. I feel it is unsafe to drive as the vehicle does not always register that it is in park. I can feel the transmission slipping because of this. I would really appreciate some support for this. It is a 2019 GMC Acadia, which is also apart of the other vehicles that are apart of a lawsuit in ohio and other states. This is a safety hazard for myself and my family.
