Previous complaint of Shift to Park on 06/13/19 VOQ 11219862 at mileage 36270. On 12/5/21, approx miles 62099 same problem with Shift to Park. Was scheduled for service on 12/06/21 at Adams Buick GMC in Richmond, KY and mentioned the problem and previous complaint. Was told that it had been over a year ago but that they could fix it and charge me $152 for part & $315 for labor. It was less that 26000 miles driven since the last issue. After last complaint, the dealer contacted GMC and the part was replaced at no cost under bulletin for concern # 5 145420 and they replaced the transmission control assembly. This is an ongoing problem with GMC and I don't think that every 26000 miles I should have to pay to replace the same part when GMC knows it is a problem by the numerous complaints. In fact while I was getting my vehicle serviced, I spoke to another lady there who had the same problem with her vehicle. Had I not caught the message, I probably would have had to replace my battery or my vehicle could have rolled into the house. There were no warning lamps or messages prior. GMC needs to step up to the plate and issue a recall because they have numerous vehicles with the same problem. My vehicle has undergone this malfunction twice and I find it unacceptable and know that I can't afford to pay $467 every 26000 miles for an issue that GMC is clearly aware of but won't address because no one has been killed by the issue as of this date to my knowledge, but it's going to happen sooner or later if the issue is not addressed properly.

When the placed in park, the vehicle does not recognize and will not shut off as there is a message that the car in not in park, when it is. This happens frequently. I am unsure if, although I've placed in park, the car itself recognizes that. There are times where for several minutes I cannot turn my car off even after shifting in and out of park.

My 2017 keeps having transmission issues. At the dealership the transmission fluid is burnt. The 2017 GMC Acadia limited has the same issues with the engine as the standard 2017 GMC Acadia

This vehicle has twice had parts replaced for the "Shift to Park" issue detailed in GM TSB 19-NA-206. The first incident was in April 2019, and it was repaired under warranty at about 24,800 miles. The second incident was this past week at about 50,800 miles, and this repair cost almost $800 to fix. I contacted GM customer support and was told that I could not get any reimbursement because there was no special coverage or recall for this known problem. This is completely unacceptable, since the problem is clearly a defect in parts manufacturing or assembly, and it renders the vehicle completely unusable since it is impossible to turn the car off when the car does not recognize that the shifter is in park. This is a safety issue because the driver needs to be certain whether or not the vehicle is securely parked before leaving the vehicle.

I have experienced the same problem as a multitude of Acadia owners as is well publicized via the Internet and class action lawsuits, which are now beginning initiation. My dealership tells me they have a lot of customers with the same problem which usually starts when the vehicle has around 15K miles on the odometer. The problem is the Intermittent Shift to Park display on the Information Center. It tells me that the shifter is not in park position when I go to turn the engine off, but it really is in position. When it happens I cannot turn off the automobile without restarting it. Sometimes it will turn itself off after a few seconds without any intervention on my part, sometimes more, sometimes after I jiggle the shift lever, but many times I have to restart the engine one or more times to turn the vehicle off. If the system can't be sure if I'm truly in Park position, how can it be sure that the lever is really engaged which would enable the car to roll away. I have had it back for repair service twice during the bumper to bumper warranty period to resolve the issue based on GMC guidance. That service tends to resolve it for a while but it always comes back again after a period of time. The last time I was told a jumper was installed so I should never get the problem again but it has returned and have had quite a few occurrences over the past two months. There is absolutely no pattern to the problem. What is really frustrating me is that I recently took it back again (after my bumper to bumper warranty was over) and they tell me there is another service bulletin from GMC which says the original shifter cable is too short and they need to install a longer one. Now they want me to pay $375 to install the new cable which is WRONG WRONG WRONG in order to resolve a GMC safety issue which was the result of an original design issue by GMC. I refused as this must be covered by GMC and should be the subject of a government mandated safety recall.

Shortly after I purchased my Acadia in may of 2018, it started displaying a shift to park warning when I would put the car in park. I contacted the dealership and they said it was a known issue and they had to replace the shift assembly. Well about 3 weeks ago it started doing it again. Only this time it's worse. It takes several tries and tricks to get the car to recognize it's in park and allow me to shut the car off - when the warning pops up it won't allow the car to power off so all the electronics stay on. I called the dealership and they told me because my extended warranty expired at 79,000 miles and they had already replaced the shift assembly once that there is nothing they can do and I will have to pay out of pocket for this repair even though it's a well documented issue with these vehicles.

After putting the car in park and turning it off a 'shift into park' message displays on screen leaving the car still on. Very dangerous when I always have my 3 kids with me at all times. We have to keep messing with it until it goes away before we can safely get out and feel confident its ok to leave the car.

The vehicle gives a 'shift to park' warning on dashboard after vehicle ignition button. This warning shows up every time the vehicle is accepted to shut off. It takes several minutes and tries to get the message to go away and the vehicle to completely shut off. The only successful way of getting the message and vehicle to completely shut off is by wiggling or shaking the gear shifter until it goes away. I have been stranded with children in the vehicle for concerns that the vehicle will roll with the vehicle not registering that it is in park. After researching the vehicle issue further it has been found that other owners with the same year and model have had the same shift to park message and have had their vehicle roll on it's own. The vehicle has gone to the dealership to be fixed but unfortunately because my warranty has expired I am being held responsible for paying to fix this safety issue.

Shift to park message comes up randomly, when parking vehicle. Had electrical harness replaced in 2019 for this problem, then hardly drove in 2020. Now the dealership said I need to replace the shift control assembly at a cost between $300-$400. They indicated the bumper to bumper warranty is expired, and I would have to pay.

The airbag light on this car has been going off and on since it was purchased in October 2017. Every couple of months there was another problem with the airbag. The dealership could never diagnose the problem. They initially claimed the sensors were unplugged as a result of moving the seat back and forth. Now that the car is out of warranty, they want to diagnose the problem as a faulty sensor. Additionally, the automatic transmission shift to park issue is occurring. This is when the car is parked and the transmission shifted into park, however, an error indicator displays saying the car needs to be shifted to park to turn off, even though it is in park. The dealership replaced the manifold 2 years ago and now the problem is resurfacing.

Shift to park issue - when shifting into park and subsequently turning off the vehicle, the vehicle will show a notification on the dash saying 'shift into park' and will not allow the vehicle to shut off. The vehicle does not recognize the shifter ind the park position, will not turn off and will allow the vehicle to roll freely. This is a safety issue for multiple reasons. First, the vehicle while in the park position can roll freely. Second, the vehicle will not turn off and engine will continue to run, thereby rendering the vehicle unable to shut down.

Shift to park warning turns on when gear shifter is in park and while attempting to turn off the vehicle

- Lamar, SC, USA

At 95,800 miles the automatic transmission failed catastrophically. There was no warning of the failure. After stopping for a brief time on an interstate highway, upon resuming the trip the vehicle stared over-revving and searching for shifts. When a shift point was found there was a loud banging noise when the gear engaged. The vehicle remained driveable to deliver to a repair facility where it was diagnosed as a complete transmission failure. The vehicle has been maintained meticulously and all routine service was performed by authorized GM dealerships.
