Shift to park issue. Car will not go into park. Car will not shut off. Sometimes shifting back and forth or jiggling the shifter will work. Dealer replaced shifter assembly at a cost to me of $777. This was done last week. So far so good, but GMC knew about this problem for quite a while.

I owned a 2019 GMC Acadia Denali with surround vision system (rear camera). In December 2023, my rear camera went out and almost caused me to hit someone while backing up. I don't totally depend on the rear camera when backing, but this time when I turned around to look if anything was behind me I didn't see no one. I took my vehicle to the dealer to get it checked out and to repair it. They found that the vision process module was bad. The technician found that the vpm had internal malfunction and corrosion due to water intrusion damaging vpm completely. found code B101D for internal failure and not responding to any programming or commands. Replaced vision processing module at a cost of $1348.90. I wrote to GM explaining the problem and request reimbursement. As of today, no response from GM.

When the vehicle is in park and you try to turn it off with the start/stop button an on dash error code of -??Shift to Park-?? appears even though the vehicle is clearly in park. You are not able to turn the vehicle off. I am scheduled to take the vehicle in for service on 1/11/24. This currently is forcing me to restart the engine, put my car in reverse, shift back in drive, try re-parking and turning it off again, repeating the process until it eventually turns off. I do not know if my car is truly in gear or not. I-??m afraid that it might cause a dangerous situation.

Shift to Park car would not turn off. Had to start car, then go forward and reverse several time so the vehicle would finally recognize it was in park. - this has been going on for almost one year on and off. -??Steering Assist is Reduced Drive with Care-?? making it hard to steer. The get Service -??Stabilitrak-??, -??Side Detection Temporarily Unavailable-??, All Wheel Drive Off, -??Battery Saver Activated-??, Services -??Battery Charging System.-?? All lights went out and the car went dark! I was unable to drive the car, had to be towed. - this has happens twice. The first time was on October 2023, the mechanic put in a new alternator, thinking this was the problem. The second time happened 11/29/2023, mechanic is still trying to diagnose the problem/problems. This car has left me stranded and in fear to drive it due to the fact that I lose all vehicle driving ability!!

The touch Display screen. It has started to constantly go through every setting on the car while driving. I-??ve tried turning the screen off. It works for a few minutes and then turns itself back on. It will change radio stations. It will make phone calls if a phone is detected. It is a constant distraction while driving GMC is obviously aware of the problem. You can call a service center. They will tell you that it happens all the time and that the part will cost you around 800$ not including service charges. With how many people depend on display screens in today-??s technological ways. It-??s only a matter of time before a serious accident occurs from this, if not already that hasn-??t been reported. Also this affects more than just my vehicle. It-??s across most of GMC models. Several public forums related to this issue.

Shift to Park is not working properly. Have to start engine and shift to park as much as three times to get the light to go off and radio and bells to quit dinging. I can't tell if car is in park or not and could be dangerous to leave it.

When vehicle is put into park and you go to shut off the car it gives a message to shift to park. Diagnosis reveled that there is a service bulletin SB#19-NA206 which tells the mechanic to replace the the shift control assembly and add jumper harness to cure shift to park message when vehicle is turned off. Previous years of this vehicle model were covered under recall. This model year should also be under recall for this problem.

Shift to park error every time I park my car. It takes multiple times of shifting and what not to get the vehicle to shut off. I will be making a appointment with my dealer.

"Shift to park Warning light" comes on when turning off vehicle when vehicle is in park.

-??Shift to park-?? message frequently appears and unable to turn vehicle off, will drain battery if left on. First appeared infrequent within 1st year of lease, brought to dealership service, they were unable to reproduce and stated they did not know what was wrong with vehicle if they couldn-??t reproduce the message. Fast forward 4 years, I have now purchased the vehicle and message and condition appears very frequent almost daily. Returned to dealer service was advised by customer service manager -?? I know exactly what it is it is in the gear shift-?? but since car is no longer in warranty I would have to pay out of pocket. I attempted to explain that I did I bring it back when it would have been on warranted and was told they couldn-??t find anything wrong!!! I have replaced battery multiple times due to power drain from not being able to clear -??shift to park-?? message. Last battery lasted less then 1 year!! I feel GMC is aware of the issue and did not take care of problem when it was under warranty and is now forcing the finiancal burden to replace/repair parts to me!!!

Several times we were unable to put the vehicle in park which would not allow the car to be cut off. I went on line to read reviews about this kind of problem and found bulletin 19-NA-206 describing the shifter assembly as a common problem on this vehicle. A Gen shifter harness was replaced at a cos of $589 with a two year warranty and was told that this will probably happen again. (Gen Shifter Harness) We are now afraid to take trips now because we use to make many stops in small towns to visit relatives. My wife wants to get another kind of vehicle because of this problem. We have purchased four cadillacs and two GMC vehicles from Coulter Cadillac but no problems with the Cadillacs.

When trying to turn car off, shift into park, and a message is on the driver screen to "shift to park". The car is already in park. The car will not stop running unless the "shift to park" message is gone. After looking on internet, was able to toggle the shift gear button to remove the "shift to park" message. This started about 4 months ago, it did not happen all of the time. At first, I would have to attempt to restart the car, and then try to turn car off. After investigating this on the internet, was able to turn car off by toggling the gear shift button. This problem was not a surprise to the car dealership. Apparently it is a common problem, and a recalls have been made by GMC for this issue, but not for the year of my car. My car was no longer under warranty, so had to pay $348.04 to fix this.

I have the shift to park error where my car is not recognizing that it is in park and will not shut off. I have been held hostage inside my car, late for work, etc because my car will not shut off because it is not registering that it-??s in park. Also, my breaks are unbareably loud with whatever switch they made to the -??new-?? brake material.

Get the message "shift to park" The car is parked but it is not recognizing that it is in fact parked. It makes it impossible to exit the vehicle and turn it off. To get the message disappear and exit the car the gear has to be wiggled. I checked this online and previous GMC vehicles were recalled because of this. And it has a possibility of hurting the transmission as well. This happens quite often. So there no exact date.

I'm not sure what this is but I'm not reporting damage I'm reporting the factory model. This vehicle seating is not appropriate for the body size of the front of the vehicle. I've had two other acadias and I didn't have this type of issue. The side of the vehicle where the mirror is located is so large is can cover the view of two cars. And even adjusting the seat doesn't help. You literally have to lean up to loom out the front windshield to make sure you are in the correct place. It's a safety hazard and whoever manufactured this particular car did not do so well

Steering Assist reduced drive with care" displayed on screen when I was driving. The temp gauge stayed on C, Heat works fine, Happened for a few days.

A week ago my car started having an alert on the dash saying -??shift to park-?? when I was already presumed to be in parked. I was worried because the car wouldn-??t turn off and stayed on dinging. I couldn-??t leave my car because it was on (possibly having battery die or doors won-??t lock, etc.) I researched it and it showed many GMC Acadias have done this and previous models has recalls. As a result, the vehicle could roll away once you get out of it, putting you and the people around in great danger. Also, you may not be able to restart the vehicle once the 'Shift to Park' message is displayed, making it a terrible inconvenience especially when you're in a hurry. I took my car in to be serviced and they said it was that I needed a -??new shifter assembly-?? so $670 later and after reading that this is what mechanics first step is, but essentially may not even fix the problem kind of terrifies me. A recent recall report says that GM does not currently have a fix for the Shift to Park issue just yet, however, it does have fixes for "Shift to Park" messages that can appear in affected Acadia vehicles that are already in PARK On October 3, 2018, GM released a TSB entitled "Message Displaying Shift to Park When in Park" which instructed technicians to correct the defect by replacing the transmission control shift assembly. While there are some fixes for "Shift to Park" messages, GM still has no fix for the actual Shift to Park issue. What do we do" Pay a large fee for a possible half fixed issue"

Every time I go to turn off the engine it say shift to park and then I have to restart the truck and keep putting the shifter into park a couple of times for it to not happen.

I am getting a warning message to -??shift to park-?? when I am already in park. I have to shift back and forth for the message to go away and am not confident if the suv is in gear or not. This apparently is happening with many GMC Acadias.
