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.

Vehicle when shift to park would indicate the shift was not in park. When I got the vehicle new is when it started. I have put up with it by pressing hard on the gear shift and checking it before turning the car off.

When the car is shifted into park, it often does not show that it is in park. It will roll, the lights will not go off, doors will not lock. To get it to work, you must restart the car and move the shifter in and out of the park position. While you are doing this the car will continue to roll with the brakes depressed. The service writer at the dealer stated that this is a common problem with this model. This has happened at least 10 times.

When you put the car into park the computer does not recognize that it is in park, you may have to restart and re-put the car back into park several times, also the light will not go off, the doors will not lock, the battery will run down and the car will roll.

When I put my car in park I get a warning that says my car is not in park action required. The vehicle bell continues to ding and will not allow me to lock the car. My fear is getting out the vehicle and it starting to roll not knowing if the vehicle is actually in park. This is very scary not knowing if it is safe to get out of the vehicle.

Began in Sept 2019 - when I park the car I would get a message saying "action required shift to park" even though it's shifted in park. I have had to shut the car on and off a few times before it goes away.

Beginning in mid-October 2019, when I attempt to turn off my Acadia, I get a message that says, "action required. Shift to park". it will not allow me to turn my car off or exit the vehicle and lock it. In order to circumnavigate the error, I must turn my car back on, shift to drive, shift to park and turn my car back off. At the minimum, I must complete these steps three times to get my car to a spot where it will allow it to turn off. This only occurs when I am in park, attempting to exit my vehicle.

2017 GMC Acadia has 'shift to park' error for the last 6 mths. Will not acknowledge the car is in park and will not turn car off completely. It has caused other issues with the car like battery/car hesitating to start in the morning. Also the radio/bluetooth not disconnecting after turning car off. You have. This is a long process to get the car to realize it is in park. After turning car on and off, shifting car out of park and back into park. And also wiggling the shift gear. This after knowing it is an on hoing issue for well over a year is still not a recall and they still have not made a fix for this.

Shift to park error when car is correctly in park. This does not allow you to shut off your engine. I have had the shifter replace twice already at the dealership. I know it will happen again.

- Conroe, TX, USA

I have a 2017 Acadia. When the car is shifted into park, the dashboard shows a warning that says "shift to park" even though the car is already in park. I have to turn the car off and on several times and slam the shifter into park until the car finally registers that it's in park.. if I leave the car like that, all the electrical stuff stays on and my battery will die. Additionally, when this happens, the car is not in park and seems to be in gear or at least in neutral because it will roll. This is a safety hazard and happens on a daily occurrence.

When I turn my car off, I am getting a 'shift to park' error code even though the car is in park. If you ignore it, the car acts as if it is still on, lights and radio won't turn off. When I got my son out of his car seat the car started moving a little even though it was off and in park. You have to turn the car on and off multiple times and shift the car around to different settings until it just decides it's finally in park. This is dangerous and what happens if one day it just decides it won't go into park no matter how many times you try and apparently through research this is a known and common issue yet a recall has not been issued.
