My 2017 GMC Acadia with 40,000 miles on it has been saying 'shift to park' when I try to turn it off. The only way to get it to turn off and be safely in park is to continuously turn it back on shift to reverse or drive move the car a few feet and try again. It continues to take multiple times and the only thing to 'fix it' GMC claims is to replace a lever and that takes 5-6 hours at 135$ an hour and 2 150$ parts. It is not covered under warranty and is a huge safety issue as you either cannot get the vehicle into park and have it safely stuck or it will continue to stay on and possible roll away. There are hundreds of thousands of forums and posts about this issue and even the people who got it 'fixed' still have issues. It is a safety issue and GMC needs to figure out what is causing it how to fix it and do an emergency recall if they cannot figure it out then they need to fully recall the 17-18 Acadias and provide replacement vehicles as this is a major safety risk. I cannot be stuck at a place during a global pandemic because my car is stuck due to an issue that GMC cannot fix.

When putting vehicle in park and trying to shut the vehicle off there is an error message that comes up on the display that says to put the vehicle in park. I have to try a couple of times to put in park to get the error to go out so I can shut the vehicle off.

Starting about a month ago when I put my car in park and then turn my vehicle off a 'shift to park' warning comes on and the car will not turn off. The car is in park and I have to shift to a different gear and back to park trying to get it to register it is in park. Sometimes it takes multiple times of trying this before it will recognize it. My vehicle is past the 36,000 miles with about 42,000 miles.

I bought a 2017 GMC Acadia, and have not even made a payment on it yet. It just passed the 36000 mile mark. I have been getting a shift to park warning each time I park to shut off the vehicle. The vehicle says it is in park, but it keeps sending the warning. I have to put the car in reverse and then drive several times before it will turn off without the warning.

Beginning in may, 2020, my Acadia started saying "shift to park" when I would try to shut it off, although it is in park. It has increasingly gotten worse and it now happens every day. This morning. I had to restart the car, move backwards, forwards, shut off car and repeat 7 times before it finally let me shut the car off without the warning.

I receive a 'shift to park' warning message when my vehicle is clearly in the park position and it prevents my car from being able to completely turn off. I have have had this same issue supposedly repaired at the GMC dealership on two separate occasions and it is now giving me the same error. I am now no longer able to open my garage door from my vehicle, I have had several instances in which the vehicle does not recognize either one of my key fobs.

When I pull in somewhere and shift my car into park and then go to press the button to turn it off I get an ' action required message' on the cluster to shift to park even though it is in park already and it shows on the cluster that it is in park. I took the car into the dealership to repair the recall and have it serviced while it was there and informed them of the issue and to get them to check it out. They said they were not sure what it was but it kept throwing a low voltage code. But when the battery was checked it was fine. They found a bolt loose or missing on a battery cable at the junction box and replaced it and said that they thought that was the problem. But the problem returned a day later when I was on a trip to nashville. While in nashville I again went to the auto parts store for my daughter and pulled into park and got the same ' shift to park message when I was already in park. The cluster on the dash showed that I was in park. I got out to go ahead and run into the store and when I came out my car had rolled backwards across the parking lot to the curb. Luckily it did not hit anything but the curb and stopped. This problem is so dangerous and concerning to me. It is going back into the dealership to get checked again. I did find a youtube video explaining what the problem was in the shifter and why it was not recognizing that the car was in park. Look in the search bar for GMC Acadia shift to park problems. I feel this needs to be a recall so no one else S car ends up hurting someone. I have no video of this happening because the cameras at the auto parts store were not operational and no one was around when it happened to see it but me.

The first problem I had was the shift. I got it fixed. I have it all documented. Now for the second time in the past 2 weeks my car has flashed every warning light possible. I took it in the first time and was told the codes did not store and to keep driving it. I finally got a video of the problem happening and dropped it off for a second time. During the problem all gauges go to zero and the gear symbol disappears. The last time I drove the car it accelerated on its own and I did not have control of the vehicle.

When in park, a 'shift to park' message appeared and I could not turn off the vehicle. Had to put vehicle in gear and try putting in park again. Did this several times and the error message went away.

The car will not shift to park! it says shift to park! this is becoming more and more of an issue. The first couple of times I figured it may have been a fluke but lately it is anytime the car is driven and I need to park.

My vehicle has been nothing but trouble since I purchased it in June 2017. First, the car came with the wrong door handle on one of the doors that took 3 months to fix because the dealership screwed up the paint on the door and had to paint practically the whole car. And initially the dealerships and GMC corporate gave me the runaround with who was paying for the bill which the consumers should not have to deal with. Then the car had a shift to park issue in July 2019 which GMC would not replace at their cost even though they released a notice to the service departments about it because a number of people were having the same issue but never issued a true recall notice because they wanted the consumer to get stuck with the bill. And since then I have had issues with my mirrors not staying programmed and the air venting automatically switching to letting air in from the outside without me changing it. Then my car battery started going out February 2020 which should not be happening in less than 3 years of this car being purchased. And now my radiator (which is estimated at close to $1,000 to replace) is leaking; again this should not be happening this soon unless this car is a lemon. GMC won't take responsibility for any of it with this car and this is more problems that anyone should ever have with a car within 3 years of purchasing it brand new unless it is a lemon car which at this point, I think mine is.

I attempt to place my Acadia into park and power down my vehicle only to get a "shift to park" error message. I am unable to power down my vehicle and not fully park my vehicle even though I have parked it. This occurs daily and has occured 15-20 times in 1 attempt to park. I have to attempt to turn car back "on" and then put car into drive or reverse driving about a foot or so than attempt to repark my vehicle. Only to have to repeat this step over and over til it finally disappears. GMC customer service associate claims they are unaware of the issue. Of course this issue only occurred after my vehicle warranty expired.

Shift into park indicator light comes on even though it has been shifted into park. Cluster won't shut off upon exit.

- Maywood, MO, USA

When the vehicle is put into park(stopped) and turned off the car does not recognize that it is in park. So now it says "action required shift to park" (the gear shift is in park). The engine will be off but the lights, radio anything tied to the battery will not turn off. This runs down the battery if you cant get the card to park. Dealer ship will not fix

The vehicle has had ongoing issues since it was purchased in June of 2017. The 'shift to park' problem had to be fixed twice, the emergency braking system engages itself for no apparent reason which has almost caused several accidents, the horn does not work when needed in emergency situations, the headlights are so dim it's dangerous, the battery has drained and left my wife stranded 4 times, and the vehicle has a very rough idle and it almost stalls out. I attempted to work with GM to have them take the car back early (lease) and the request was recently denied. This is my 3rd Acadia and it by far is the most dangerous car I have ever driven. I am now reading about a fuel pump problem that could cause the vehicle to catch on fire, a driveshaft that may separate while driving, and a faulty braking system that could cause the vehicle to lose all braking capability. I do not feel safe having my family in this car and I am requesting your assistance to help me work with GM on a resolution. I entered the date that the vehicle first started to have issues, there have been over 20 incidents over a 2.5 year period causing a safety issue or leaving my wife and children stranded.

2017 GMC Acadia would issue a warning saying vehicle failed to shift to park even though the vehicle was in park. This vehicle defect is known by GMC and their dealerships. A lawsuit is currently pending regarding this issue. GMC has failed to issue a recall and has failed to resolve the issue. We took our vehicle to the local GMC dealership August 2018 due to the issue. The issue started again in November 2019. When we called about it, they said the prior work wasn't covered and we would have to pay to have the "known defect" repaired again.
