Check engine light comes on, engine temperature gauge stops working engine fan runs on high only. I have replaced the thermostat/sensor once already and now it needs to be replaced again.

- Cottage Grove, OR, USA

When the vehicle is put into park and I turn the vehicle off I get an alert on my console saying "Shift to Park". I called GM customer service and was told "harness" had been replaced in 2020. I bought the vehicle in 2021. Last year I had to replace the "harness" and it is doing it is now doing it again.

- Winchester, KY, USA

When I turn the ignition off it sends me a message that I must shift to park. The car is in park at that time that I get the message. I restart the car and move the shift to reverse or drive and move the car and place in park and that may correct the problem or I may have to do this once, twice even three times before it corrects. The warning bell will continue to ring and the radio continues to play until I can get the situation corrected.

When put in park it dings for a long time shift to park. I have read that this is an issue there has been recalls but mine is not on recall. However this does this like every other time I use it. I-??m worried I will be left stranded with dead battery

with the "Shift to Park" function, where the vehicle displayed the message even when it is in park, preventing the me from turning off the ignition

- Wilton, NH, USA

When putting my vehicle in PARK and pressing the button to shut off my car, a warning appears on the dashboard saying -??WARNING: PUT VEHICLE IN PARK.-?? & it is in park. I have to wiggle the gear shifter in order for the warning to go away and if it won-??t go away, then my car won-??t turn off. There was a recall on it in 2018 & I need mine fixed. Somehow, my vehicle was not apart of the recall but it needs to be. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Car gives -??shift to park error-?? around every 5th time I turn it off. I have to turn the car back on and repark it to be able to actually turn off

- Crown Point , IN, USA

Shift to park error message consistently displayed forcing repeated restarting of the vehicle so that it finally recognized that the vehicle was in park and would unlock the doors for safe exit from the vehicle. This was a known issue by General Motors and they have 2 class action lawsuits filed n the states of Ohio and Tennessee for this issue with well over 110,000 vehicles affected. General Motors refuses to acknowledge this defect and fails to issue a recall. Their only offer when I took this vehicle to a GM certified dealership was to offer 15% towards the replacement of the shifter assembly. The excuses made were the vehicle was out of warranty as well as over in mileage. I bought this vehicle used from an Acura dealership and accepted delivery of it on [XXX] with approximately 33,417 miles. I started to experience the shift to park error message at 36,013 miles in early May 2025. By the time I was able to receive instructions from GMC customer care and secure repair for this issue the vehicle mileage was approximately 37,000 miles. It is not a pleasant feeling to be trapped inside your vehicle until you can get it to finally recognize that the vehicle truly is in the park mode. With the hundreds of thousands of vehicles on the road with this issue I feel GM should recognize their problem and perform a vehicle recall. This flaw had been installed in numerous GM vehicles manufactured as early as 2017. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

When vehicle is placed in park, it is still showing a "shift to park" message once car is turned off.

- Grayson, GA, USA

Since buying my 2019 GMC Acadia multiple times a day my auto shift to park will not allow me to lock my door as normal. It says there is no recall associated with my Vin Number however my particular Year, make and Model has the same issue. Please make this make since.

- Bartlett, TN, USA

We receive a shift to park message when we try to turn our 2019 GMC Acadia off. The vehicle is already in park, but an alarm bell keeps going off telling us it is not. The vehicle will not allow us to shut off the vehicle properly and results in battery drain and inability to lock the vehicle. We have noticed there is a class action lawsuit and recalls from previous year's models and the 2019 model manufactured in Ohio, but ours was manufactured in Tennessee. Our year, make, and model isn't listed in the class action lawsuit and/or a recall. This is very frustrating considering the number of similar issues/complaints in regards to this shift to park problem. I feel GMC as the manufacturer should be held liable for a faulty part and they have failed to correct this issue in later models since they were aware of the issue with the 2017-2018 Acadia models built in Tennessee.

- Pocatello, ID, USA

Shift to park issue. This 2019 Acadia Denali has been serviced twice for a shift to park issue:(It-??s a known problem that occurs when Acadia vehicles fail to recognize that the gear shifter is in the park position). The first time was under warranty in 2022 and it has just been serviced again for the same problem. The system is the same as the older GM recall for this problem and the recall should also include this model as well but unfortunately it does not.

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.

-??Park to shift -?? warning keeps showing up when shift the gear to PARK.

- Oxnard, CA, USA

My 2019 GMC Acadia with 33,000 miles on it started to give me a notification to "Shift to Park" even though I had already shifted the vehicle into park. A "ding! ding! ding!" alarm wouldn't go off and the vehicle wouldn't turn off unless I repeatedly changed the gears until it read it was in park. This went on for a few weeks and got progressively worse. I read on a GMC forum that the vehicle could slip out of gear while driving and potentially cause an accident. My mechanic found the shifter assembly to be defective and replaced the entire Gearshift Lever Assembly. He said there was a plastic piece in the gearshift that snapped off and said this was an issue in the older models but thought GMC had fixed this issue by 2019. Unfortunately, I was past my 3 year / 36K mile warranty and had to fork over $1300 to have it repaired.

- Rochester, NY, USA

I am receiving a "Shift to Park" notification on most instances that I shift the car into park. When this warning engages, the car will not allow me to turn it off as it does not recognize that it is in park. After researching this issue, I found that there is a GM Recall for 2017-2019 GMC Acadias for this very issue. However, my VIN is not included in the recall so I do not qualify to have the issue fixed and would have to pay a substantial amount out of pocket.

- Tyler, TX, USA

Some times when vehicle is shifted into park it doesn-??t recognize it is in park. I have to turn the vehicle off and restart it, shift into drive and back into park. Sometimes it takes a few times. My neighbor has a 2018 Traverse and had the same issue.

- Charleston, WV, USA

When you go to park the car and put it in park the car says shift to park with it already being in park. It is concerning that the vehicle is not recognizing it being in park
