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.
Getting a “Shift to Park” message when the vehicle is already in park
When the car is put In park there is a message that appears on the display when pushing start/stop to turn the car off "shift to park". The car has already unlocked and it turns off and restarts but the message keeps popping up
There is a “shift to park” message. The vehicles fails to recognize that it is in park and display a message urging me to “Shift to Park.” When this happens, I am unable to shut the car off, and this could cause my vehicles to roll away if it is not properly in Park. I would have to constantly wiggle and move the electronic shifter to get it to recognize that the shifter has been placed in the ‘Park’ position. This has resulted in me getting stuck in my car until I get the message to stop, which often time takes several tries and minutes.

Vehicle is constantly giving “shift to park” error. The steering mechanism has also been compromised, and the vehicle makes persistent jerking motions with accelerating. This could be quite dangerous.
Traveling at interstate speeds the vehicle had an short in the Body Control Module due to the HVAC drain leaking into the vehicle. The vehicle displayed a series of alarms brake, steering, and shutoff. We had no power, steering, brakes, or lights. The issue was discovered by Dave Sinclair dealership. It had been in for a sensor issue 3 months prior.
Ongoing problem with only solution is a recall notice. Power Steering Assist Reduced -Customer reports Power Steering Assist Reduced message displayed on DIC, A/C is inoperative, Engine Coolant Temperature Sensor inoperative. Recall needed to update Engine Control Module (ECM) with latest calibration.
Im getting new tires on my car and was told the alignment cannot be done due to the rear tow links needing replaced. I was told it's a known issue with Acadias and should be covered under a recall I called my dealership and it's not a recall.

"Shift to park Warning light" comes on when turning off vehicle when vehicle is in park.
I just purchased this vehicle and within a day, it was already giving an alert that something was wrong. Says "action required, shift to park". My car was in park. It was not shutting off due to the notification, which leads your battery to drain. The next day, as I was driving with my kids, the headlights start flickering, and then shut off. It left us driving in the dark and nearly causing a wreck because someone didn't see us coming because it was too dark. The dealership said they look at it, so I don't know what will happen moving forward. It's definitely not safe unless the issue is addressed.
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” 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!!!

Thermostat gets stuck, generally in open state. AC also is disabled in this condition, soft code (no MIL) mentions "limited steering available" and temp gauge on dash goes to 0. Hard code eventually comes (solid Check Engine light on the dash). Code, MIL, and temp gauge can be cleared and fixed by disconnecting battery negative terminal and reconnecting it, and it will run consistently for a while, though it will return. Online there are no thermostat modules for this engine available (3.6L V6, also in Cadillac XT6, Buick Enclave, and Chevrolet Traverse) showing that thermostat replacement is widespread. Online forum searches also describe widespread thermostat issues for this engine, at roughly $1200 per fix. A reliable thermostat is critical for long-term engine functionality, and should not need replacement at half of design life (~75-80k miles). Though this one tends to fail open instead of close, overcooling of an engine still could have its own issues, and failing closed could lead to engine overheating.
The shift to Park locks up and will not allow the vehicle to turn off. Receive an error message that the vehicle is not in Park.
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.
2019 Acadia originally displayed a shift to park message at 12K miles and vehicle was still under warrantee. New shifter harness was installed and a wire harness jumper added. GM covered the cost of repairs. At the time I was told hopefully the repair fixes it but a chance it won't and will need to bring it back in. Two years later at 36K miles it occurred again but was out of bumper to bumper warrantee so GM would not cover and dealer would not give any discount. Both the dealer and the GM claim rep I talked to were not able to adequately explain why this is not considered in the powertrain warranty which is still valid. GM did reimburse 50% of the cost of repair but I am still out ~$380. This issue seems well documented across numerous models / years of GM products.
The contact owns a 2019 GMC Acadia. The contact stated that upon parking and attempting to turn off the vehicle, the message "Shift to Park" was displayed. The contact restarted the vehicle and was able to successfully park and turn off the vehicle after several attempts. Additionally, while driving at various speeds, the vehicle intermittently failed to shift as intended. Additionally, the A/C system was inoperable while driving. The check engine warning light was illuminated. The vehicle was taken to the dealer, where it was determined that the cooler and thermostat needed to be replaced. The parts were replaced; however, the vehicle was not serviced for the transmission failures. The contact stated that the vehicle was difficult to start, and the doors failed to close intermittently. The vehicle was taken to the dealer, where the battery was replaced. The contact stated that the transmission failure persisted, and there was an abnormal odor coming from underneath the hood. The vehicle was not repaired. The manufacturer was notified of the failure, and a case was filed. The contact was referred to the NHTSA Hotline to report the failure. The failure mileage was unknown.
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.
Steering assist warning came on and my wife panicked. She was on the highway and it came on and she could fill it in the stereo wheel. Temperature gauge stays on 0.
The contact owns a 2019 GMC Acadia. The contact stated while driving 55 MPH, the electric power steering (EPS) warning light illuminated, displaying the message "Steering assist Might be Inoperable".

After restarting the vehicle, the vehicle returned to normal functionality, but the failure had since become a regular occurrence. The vehicle was taken to the dealer, who diagnosed a failure with the thermostat. The vehicle was repaired. The manufacturer was notified of the failure but referred the contact to the NHTSA Hotline for assistance. The failure mileage was 70,000
There have been no reported recalls yet my vehicle is on it's third battery since purchasing it? How is this possible?
My vehicle didn't shift into park all the way or the ADAS didn't register it. I would have to hit it quite hard with my palm to make it register. This happened for 3 months straight and finally stopped as sudden as it started. I tried to report it to GMC and was told there wasn't such an issue.
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 contact owns a 2019 GMC Acadia. The contact stated that upon parking the vehicle and attempting to shift the vehicle into park(P), the "Please Shift into Park” message was displayed. After restarting the vehicle, the vehicle returned to normal functionality, but the failure became a regular occurrence. The Not-in-Park warning light was illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the transmission control module. The vehicle was repaired. The manufacturer was notified of the failure but provided no assistance. The failure mileage was 11,000.
Vehicle has been bucking and jerking when trying to accelerate. Going up a hill is scary (especially with my kids in the car) because it slows the car down trying to find a gear. Dealership says it's a torque converter but since so many Acadia's are being recalled for transmission issues, we feel ours should be included as well. Dealership is making us pay for a transmission flush which doesn't make sense because if it weren't for these issues, we wouldn't need to have a flush.
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!
The car is is giving a warning to Shift to Park even though the car is in park. GMC says this is a known issue and could become a safety issue but is not coving under warranty or recall.
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
After exiting the highway onto a side road, the vehicle began to shake violently (like we were on a very bumpy road). I pulled into a parking lot thinking we had a flat tire. Then the vehicle suddenly came to a stop and would not move forward and would not move backwards. There was no flat tire, but I noticed that the front left tire was turned inward in the direction that the steering wheel was turned, but the front right tire was also turned inward at a much greater angle. At first glance, I could see behind the tire that the tie rod had detached from the front right tire resulting in no steering capabilities for the vehicle. The tie rod has a large bolt that attaches it to the tire, and the bolt was missing. Had this happened on the highway just a few minutes earlier, the resulting accident could have been catastrophic. I paid to have the car towed to the dealership and when the tow truck driver arrived he took one look at the vehicle and said "this should have never happened". The dealership could not explain how the tie rod lost the bolt and there was no visible damage to the tie rod. My concern is that had this happened at 60mph, the car could have flipped or the car would have been abruptly turned into the median wall at 60mph. Tried to upload images, but could not upload.
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.
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.
Vehicle will not shift to park. Have to engage the parking brake to ensure vehicle will not roll away after shifting to park. Becuase the vehicle isn't actually shifting into park l, the vehicle will not shut off which drains the battery and leads to being unable to turnover the engine.
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.
The vehicle is a 2019 GMC Acadia with 45,255 highway miles on it. On 1/5/23, I took the vehicle to the GMC Dealer for a routine Pennsylvania State Inspection. I was told that the vehicle's rear toe links were loose and that I would not pass the state inspection unless they were replaced. Upon some research, I found out that it is unlikely that toe links would be loose on a 4 year old car with 45k miles on it. Furthermore, to my knowledge, what causes threads within the toe link to loosen is improper adjustment. The first and last toe link adjustment was made as it was manufactured by General Motors. Looking into the issue, I noticed there was a number of other people online complaining about the same issue. Having no choice but to repair the vehicle in order to have a legal vehicle to drive, I was charged over $800 which included a wheel alignment which I was told was necessary after replacing the rear toe links. In addition, I noted that there was a recall for GMC Acadia vehicles manufactured from December 2021 to March 2022 regarding the same exact issue, and as you know, loose toe links can cause a loss of vehicle control, increasing the risk of crashing and thus putting my daughter's safety and other people's safety at risk. There were no warnings or signs of the toe link ever being loose prior to this inspection.
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.
