general problems of the 2017 GMC Acadia - part 1

GMC customer care representative & local GMC service department supervisor unable to help. 2017 Acadia shift to park message. It’s difficult to turn the car off. The vehicle refuses to acknowledge the park position. Potential rollaway hazard. You may inspect. Took it to GMC service & confirmed it is a prevalent issue: transmission control 13534320 = gearshift assembly & jumper harness 84733196. This problem has been recurring for several years and I have problem solved how to shut the car off. GMC customer care rep said it’s an issue with all 2017 Acadias and tried to help. The system deemed it complicated case & escalated it to a supervisor. She read a “customer care” script. After talking, she admitted that realistically GMC would not help. Yesterday, she advised me to file a complaint with NHTSA. I read that 2 other states ohio & tennessee won class action lawsuits because of the hazardous shift to park issue. If GMC issued recalls for 2017 Acadia shift to park then my 2017 GMC Acadia should have been included. I have been waiting for the recall for several years. GMC admits the problem is prevalent in 2017 GMC Acadias. Would you please issue a recall associated with this issue and link it to my VIN. Thank you.

Vehicle is showing message of “shift to park” while trying to turn ignition off and currently in park. There is a current recall but it is saying this vehicle is not included in recall.

The transmission in my 2017 GMC Acadia needs to be replaced. According to an article from qulll&arrow, llp, transmission problems affected the 2017, 2018, 2019 and some 2020 models, however, my VIN number is not included in this. I am reporting this so it can be documented in case other owners come forward and a pattern can be established.

Vehicle has shift to park message, and will not allow the vehicle to shut down even though the vehicle is in park.

Shift to park. Car will not register as in park. Have previously had issue fixed and has started again. Was told this is a common reoccurance and would likely happen again over time even if I pay to have it fixed again. Yesterday I spent 45 minutes trying to get the car to turn off. If it says shift to park the car will not shut completely down and there is nothing that can be done. I spoke with GMC for 30 min and was finally told to unhook the battery because they have no way to make it shut off without going to a dealership which was closed at the time.

I get a warning whenever the car is placed on park with the shifter telling me to shift to park even though it’s already on park. This causes the car to not be able to turn off.

The vehicle keeps shaking specially at the first and second gear, up to 40miles/hr and at any up hills roads. I took it to the mechanic and he said that it’s an issue in the transmission and needs to be replaced. Also the engine fan randomly turns on automatically, and a warning message stating “steering assist reduced. Drive with care”.

After shifting to park and attempting to turn off my vehicle, I receive an “action required shift to park” error message. I’m assuming the vehicle is in park but I’m not certain and worry about it moving or rolling. It is difficult to get it to turn off by jiggling the shifter and turning the vehicle on and off. At times, I am not able to get it off and then the vehicle will not lock and the battery goes dead. According to my VIN there is not an active recall but brief internet search states there has been numerous reports, recalls, and lemon law returns due to this.

Shift to park. Vehicle does not turn off when in park. This recall is in effect on other 2017 Acadias but for some reason ours is not under the recall. Had this issue in 2020 and it was repaired at our cost. It is now doing the same thing.

Shift to park. Dash stating "shift to park" when vehicle has been put in park, this results in being unable to turn vehicle completely off. Have to continually move gear shift and hope that it recognizes that the car is in park, this lasted over 30 minutes of trying to get the car to recognize that it was in park. This needs to be recalled.

It is a shift to park issue. Will not shift into park. . . . Sometimes it takes several attempts before the computer reads it is in park. Then I can turn off the car the car has 130,000 miles and we are repairing the same issue for the third time.

Shift to park warning comes on & you can't lock the vehicle nor will it shut off completely. I've had to start & reverse several times before it engages/recognizes that it is in park. Obviously this is a known issue by reading all the other posts relating to this. Please issue a recall. . . .

The known ‘shift to park’ GMC vehicle defect could cause vehicle to rollaway and possibly hit someone.

When putting my car into park and turning the engine off. The car will not turn off and displays a shift to park error. The car has to be turned back on and shifted to a different position then put back in to park to try to turn engine off again. Often times this needs repeated several times before the engine will actually turn off.

The contact owns a 2017 GMC Acadia. The contact stated that while in reverse occasionally the vehicles rearview cameras do not function properly as they should. The steering assist is not fully functional warning light was illuminated. The vehicle was not taken to a local dealer. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 99,900. The contact referenced an unknown NHTSA campaign number as probable cause for the failure.

When I turn off the car it says required "shift to park" the car stays on and I can not exit the car it will not lock doors and it stays on.

My GMC although not listed on the recall list has been effected by the "shift to park" issues that plague these vehicles. I was out of town and was unable to shift my vehicle safely into park without warnings that my vehicle wasn't secured. I had to disconnect my battery when I had to park in order to prevent roll back and endangerment to other. I took my vehicle for repairs and was told it was a common problem and nothing can be done but pay out of pocket. Why? it has the same issues as the others? why can't I be recompensated for a recall issue? I have records to show it was the gear shift control and all other.

Shift to park warning stays on not allowing my car to turn off. Have to continually move gear shift in hopes it will recognize car is in park.

Within a day of taking possession of the car, September 20, 2024, with odometer reading 76,352 , warning message in instrument cluster appears stating action required “steering assist is reduced, drive with care”. Following day, a/c stop working while driving. When park, I can hear radiator fan, running full speed (louder than normal). While driving at night, headlights are not bright, specially the high beam. On September 23, 2024, took it back to dealership I purchased the vehicle. They have the vehicle in the shop to fix the issues. Vehicle was ready for pick up September 27, 2024. September 29, 2024. Message in instrument cluster screen re-appear stating “action required, steering assist reduced drive with care”; check engine light came on, remote start key not working, a/c stop working again, radiator fan running full speed and loud , headlights are still not bright, infotainment screen glitching, will not stay in home button and making clicking sound. Went back to dealership so that they can fix it. Diagnostic code : p0128. They were able to have a/c working when I left the shop. And no messages on the instrument cluster. Following day, I have all the same issues I have before. My appointment to come back in to the shop to fix the thermostat issue I was October 10, 2024, on October 9, additional problems occur on top of the issue I am having. While driving and accelerating multiple lights on the instrument cluster screen appears on top of other issues and car decelerates. The check engine light came on, steering assist reduced drive with care , parking brake, car stability comes on and message stating engine power is reduced. This happened while driving on a highway at night on my way to work. I had to have the vehicle towed to the dealership. .

Car battery does not turn off. Once parked, the display reads “shift to park”. The car is parked; engine is off. The battery stays on for hours (4 hours and counting this time).

Shift to park had this repaired in 2019 issue has popped up again. After a while my vehicle will not turn off I will be unable to walk away from my vehicle until it recognizes I’m in park. Today (29 August 2024) I arrived to work and went to turn off the vehicle and it gave the shift to park warning. This vehicle has needed the drive shaft (what was replaced during the last event of this matter), electronic control module, transmission, and thermostat have all needed to be replaced all in the first 5 years of owning it. Bought new in February of 2017.

Shift to park warning, while the vehicle is parked.

Shift to park warning had parts replaced on 7/20/20 mileage was 54842 now having same problem shift to park warning 8/15/24 mileage 73088.

In the last couple of weeks my car has started to alert me to “shift into park” when I have already put the car in park. Sometimes it will resolve on its own or I will have to turn it back on and put in drive then back in park to fix. I researched this and found it is a recall for my year of car but did not show when I entered VIN.

After putting the car in park and shutting off the engine, the message “shift to park” appears on the dashboard display and will not allow the vehicle to be locked. This has occurred numerous times since buying the vehicle.

Bought vehicle used/as is from dealer about a month after air bag recall announced in 2023. Found out it is apparently illegal to sell a vehicle with an open recall. Dealer did not disclose the recall and I did not research unfortunately. It's been over a year now since air bag was recalled and still no fix and I live in a very hot state. Should never take this long to fix something so dangerous - fatal. Lives are possibly at stake!!! also had to replace temp sensor which cost about $1,000. A/c wasn't working properly. Mechanic said they had to replace the temp sensor. Research shows this is a known issue. Also have had to replace O2 sensors and might have catalytic convertor issue.

Shift to park comes on when turning car off.

Shifter shifts to park but park will not engage. The vehicle chimes a warning that the vehicle is not in park. This was replaced by a GMC dealership under warranty in 2019. The problem has now came back. One of the parts ladies has the same year vehicle and replaced her in 2019 and just had to replace her again last month. The vehicle is out of warranty now and the dealership has not looked at the vehicle yet because my daughter drives it but she’s in college 5 hours away. There is no warnings both times this has happened.

The seatbelt alarm system does not work and the seatbelt sign does not work.

I believe my vehicle has a software issue, the temperature gauge will read cold, I will get a “steering assist reduced drive with caution” message, my a/c stops working, and the radiator fans come on full blast the moment you start the car because the temperature can not be read. I have read online forums where others are having this same exact issue. Resetting the codes seems to temporarily fix the issue, but it comes back within roughly 2 weeks. This vehicle has not even reached 60k miles yet.

Often while trying to park, the car simply won't shut off or allow me to park. I have to shift the handle a bunch of times for the car to turn off.

This vehicle has a severe water leak after rain event from body. Leaks into electrical, floor boards, roof. Dealership not able to locate water leak location. Have been working on it going on a month. We recently purchased the vehicle used.

Shift to park warning and can’t shut car off.

All of a sudden my infotainment center went blank and hasn't turned on since. I have no backup cameras or backup warnings because of this. I've taken it to an autobody but they cannot fix the issue.

The shifter does not always engage and the car will remain in gear and can't be turned off. The safety issue is the vehicle rolls forward and backwards at times. I have hit my riding lawnmower under my carport because it continued to roll when in park. I have reported an issue in 2018 and in August 2019 a repair was performed and again in 2019 a gear shift assembly was replaced, it has been confirmed there is an issue with the shifter by a tech servicing my car when he drove it. It is at the dealer now 07-24-2023 to determine the issue and repair. Shift to park will come on inconsistently, however it will roll forward without the message.
