When I put my car in park and try to turn it off, the dash shows an error message "shift to park". The car will either not turn off the ignition or allow me to leave the vehicle or lock/unlock the doors. It alarms incessently--even when trying to move the shifter around. Takes several times of restarting and shifting to get it to clear so I can put it into park and exit the vehicle. Local dealer is charging me over $2000 to repair the transmission control shifter assembly; bcm low signal; in-line shifter wire harness jumper--exactly one month after my warranty expired. It's a known Acadia (and other gm vehicle) issue--per several bulletins--na-19-206 as an example.
When I park my car and go to turn it off, it says "shift to park". The dash indicates that it is in park and it will not allow me to turn the ignition off or lock the doors.
Shift to park will not work. Sometime after 20 try’s it may work once but I have to disconnect the battery to turn off the car. I’m beside myself and cannot keep doing this. This is a real safety problem. I have children in my car and gm says there is no recall and I am expected to pay 800. 00 and then it is not guaranteed.
Car will read error code for driver assist is reduced. Which then will shut down ac and thermostat will be locked at cold. This is a known issue with GMC if you look at the forums. Should be looked into. . Read more...
After raining door locks on every door will not work. Won't lock or unlock, manually or by using the key fob. Something seems to be getting damp and shorting out . After a day or 2 the locks will work just fine when everything dries out. Seems to be a safety issue if I can't exit the vehicle. The rear hatch is the only door that works when this happens. What is the problem and the solution? this happens every time it rains. Had it to the dealer and they couldn't find the problem.
My vehicle just hit 39k miles, it has all of a sudden started giving me a shift into park warning. The sensor is not registering that its in park and will not let you turn car off. There is a recall on the 2017-2018 vehicles for this issue and but many report an issue with the 2019, when I called GMC they would not fix. How to we go about having this included in the recalls?.
It ask to shift to park while already in the park position.
Shift to park - car will not turn off after putting in park. Car is still running after several attempts of hitting the power button to turn off.

Vehicle does not know it's in park. Can't turn off vehicle. Must shake or beat the shifter knob for vehicle to see it's in park.
After noticing my ac was not cooling, I began receiving a “steering assist is reduced drive with care” notice every time my car was started. My car is more difficult to steer. It has been assessed by a certified mechanic and found that the coolant temperature probe is malfunctioning and the ecm will either need to be fixed or replaced. Due to malfunctioning power steering, I do not feel safe driving this vehicle until it is fixed.
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.
The steering assist code comes on , the temp gage goes down , and it’s immediately hard to steer . All the lights come on , and drained the battery, this has happened several times.

My 2019 GMC Acadia started having the known "shift to park" issue that is affecting these make/models. This is a known issue and GMC has not issued a recall for it, nor are they covering any cost of repair. When the car is put into park, the screen displays a message that says "shift to park". This results in being unable to turn the car off. The vehicle will not lock either when the message is displayed. On several occasions, the car would not start because of this issue. We took it to the dealer and they are fixing the issue for just over $500 usd.
There have been no reported recalls yet my vehicle is on it's third battery since purchasing it? how is this possible?.
For a few months I intermittently get an engine light on, the temperature gauge goes to zero, the ac stops working, and an error that driver assist in unavailable. This will happen for a fee days and return to notmal where everything is fine. This happens on and off again. I google searched this and it is a huge problem with GMC Acadias. I used an obdii scanner and get a p0128 coolant error when this happens even though the temperature is fine. I just recently went over the new car warranty and GMC will not tell me if this is covered or not.
The vehicle’s steering assist reduced, drive with care notification came on. The vehicle lost steering assist control and made it very difficult to steer. The slightest move causes a major shift in the intended direction. This is very dangerous.
When I put my car in park and try to turn my vehicle off I get an error message saying “shift to park. ” the problem is the car is already in park and I am unable to turn the off. I usually have to start the car back and drive back and forth before the car actually recognizes it is in park. Im concerned for my safety.
The vehicle would continuously not register as being in park.
Initial battery died completely when vehicle was 2 years old (17 months ago). This week got a steering assist drive with care message and everything pointed to codes signaling low voltage. Battery tested with a bad cell. Gm will not cover the cost to replace a battery when not one but two have gone bad well before the middle of their earful lives. Gm claims there is nothing electrical drawing from the battery causing both the go array. Bad customer service on gm’s part. Logically this issue should be covered as it is not a typical maintenance replacement. It’s something causing two batteries to go bad!.
Gear shift notification problem. Unable to turn engine off after receiving "shift to park" message and the gear shift is visibly in the "park" position. In addition, the doors would not lock. My wife was forced to stay in the unlocked running car in a store parking lot for 25 minutes, until the car just "turned off" on its own. Unsafe for a woman (or anyone) to have to do at 10:30pm. This puts drivers in a really vulnerable position. Vehicle taken to dealer Jan 30, 2023. Was told they were familiar with the problem.
Vehicles shift lever doesn't always go into "park" and when the 'stop' switch is pushed the instrument panel displays notice to "shift to park" even though the operator has already done so. The audio still plays after the vehicle door is opened. So I assume the vehicle is still using battery power.
Vehicle refuses to turn off due to "shift to park" error being displayed. Vehicle also gives "driver assist unabled. Drive safely" message and ac will not cool and vehicle coolant gauges will not work.
While driving the all the the service lights came on on the dashboard and the system as well as the stabilitrak notification.

Upon arrival home the car would not start but would not power off either and the a "shift to park" warning message is displayed.

This error code is a know issue with the shifting mechanism GMC has been putting in Acadia models for the last 5 plus years with no proper resolution to correct potential hazard for consumers. Recall bulletins are in place for some 2009-2017 models currently,but only a temporary fix. Consumers are expected to pay for repairs for a manufacturer defective part that doesn’t meet NHTSA requirements. I would like to add the 2019 models to this list. Vehicle was inspected by GMC dealership and master mechanic.

My 2019 GMC Acadia is now undergoing the same repair for at least the second time. This is the common issue known as the shift-to-park issue. You can read about it here - [xxx] below are the commonly affected years: 2017 – Acadia 2018 – Acadia 2019 – several models (I own a 2019 GMC Acadia) 2020 – several models 2021 – Acadia and traverse despite falling into the year, make, model and issue - when I look up my VIN - no recall or warranty information is available, saying that my vehicle is not affected by this issue. However, this is now the 2nd (maybe 3rd) time I am having to come out of pocket to have this issue repaired. It originally happened in July of 2022 with around 40-44k miles on the vehicle. It is now happening again may of 2025 with around 72k miles on the vehicle. If I search further back, I imagine the first owner may have had the same work done too. Clearly this vehicle is affected by the issue buy according to my VIN it is not. Gm (general motors) told me that they offer no sort of help or reimbursement unless my VIN is associated with the issue. Can you guys please either add my VIN or extend out the warranty / recalls to all - because this is absurd. My car doesn't recognize that it is in park and stays on, preventing me from shutting down the vehicle / engine. Asking me to "shift-to-park" information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
About five months ago, my GMC Acadia started displaying a warning when I would put the car in park, and try to turn it off. The engine would shut off, but the electrical portion of the car would stay on, and would not turn off, because the warning displaying said "shift to park". I have tried every conceivable way to try to get this to go off, but nothing works. My car has stay on for upwards of two and a half hours, to the point where my battery died in the car and left me stranded. There have been numerous accounts of this, as I had read them on forums, yet still no resolution has been published. I have tried taking it to be inspected, but nothing ever comes up. I have two very small children, and if I were to be in public and be stranded because my car wouldn't turn off. . . . I would be livid. . Also, because of this warning, it prevents the doors from being locked. That is another major concern for me, considering the day in age we're in.
The electrical and gear shift failed, causing a problem that GMC calls “shift to park. ” even when the car is placed in park, the car does not recognize that it was placed in park and cannot be turned off, preventing the driver from leaving the running car. This is a known problem that multiple dealers are aware of and there even appears to be a recall and lawsuits on the 2018 Acadias. However, on my 2019 Acadia, which has the same problem as the 2018 vehicle, this is a problem that costs hundreds of dollars to fix. This should be recalled because it renders the vehicle a safety hazard because it cannot be turned off and it is a known GMC problem that they refuse to fix.
Constant issue of doors not locking or unlocking with key fob. Doors do not lock when put in drive or unlock when put in park. Buttons on the door to lock/unlock do not work. Have had at the dealership 4 times and still the issue hasn't been fixed. They replaced bcm and harness and the issue still comes and goes.
2019 Acadia will be shifted into park and parking break applied. Vehicle will then be turned off. When opening the door a message appears on the dash stating "place vehicle into park". It takes multiple times of turning on the car, shifting into another gear, then shifting back to park for the vehicle to realize it is in park to allow vehicle to shut off. It has happened multiple times. We then received an email from on-star there is a diagnostic code sac001 (battery service) needs to be addressed. This is unacceptable for a vehicle to be this new and have electrical issues.
