2019 GMC ACADIA Unknown Or Other Problems

My park to shift to park warning keeps coming on. It was replaced under warranty once and came on again comes and goes and dealership is not replace it again saying it isn’t tripping a code so it won’t get covered under the parts warranty.

Shift to park caused by a faulty micro switch. Woukd take up to 30 min to get car in park, leading to engine shutdown failures and possibly battery drain I did replace battery before I knew this was causing this. Messages did appear saying this was an issue ,must shift to park but no indication of how to do it. I got this repaired at barkley GMC Dec 29:30

Won't shift into park alert came on. Vehicle wouldn't shift into park. Danger of vehicle roll off? Took to GM dealer who replaced GM part 13545094 transmission controller aka shifter assembly. It is believed this defect was detected and recalled on 2018 GMC Acadia models. My 2019 was made in 2018. In service date 10/04/18.

Shift to Park Issue - this is a know issue/recall for the 2019 GMC acadia yet it when I enter my VIN number the recall doesn't show up as a problem. YET it took me 10 tries yesterday to try and turn my car off because each time I went to turn it off, I got the message to Shift it to Park. This has been occurring weekly since I purchased the used car in August 2025.

There are 2 issues im experiencing. The first is the vehicle won't allow me to shut down the engine because it doesnt recognize that its been shifted into "park". Ive already paid close to 800.00 to.have this repaired because my model year is not covered in the recall. Today, it started doing it again. The safety issue is that either I, my wife, or my teenage daughter (depending on who is with the vehicle). Can be left stranded, unless we pop the hood and disconnect the battery. The second issue is that the tire pressure monitor is no longer working. It is sending warnings that our tire pressure is low. When its not. The safety issue is needing to pull to the side of the road to check the tire pressure and also not knowing when the vehicle may actually have a low tire.

Vehicle is in park, and the shft sensor does not recognize the shifter is in park. Won't let you turn off rhe car.

Shift to park error message when in park.

Thermostat stuck open and a steering assist light came on engine temp needle at zero. Check engine light came on, Had to have thermostat and coolant engine temp sensor replaced

I'm going to have to replace my thermostat and most likely my sensor. It will pop up saying (steering assist is reduced drive with care) my temperature gage on my dash will sometimes will not go up, my heat is acting funny. I've had also when I put it in park saying it's not actually shifted into park.

When in park the car is alerting to “shift to park”.

I bought a car about 2 months ago and they did not tell me the thermostat was bad and they won’t cover it.

shift to park issues when placing the vehicle in Park

The put in park shows after engine is turned off, have to restart and shift out of park and back to park. This could take several times to accomplish.

I do not have current recall on my vehicle, but my vehicle is experiencing the "Shift to Park" issue that many of the same year make and model mine is experiencing. I am unsure why my vehicle would not have one. It is messing up the transmission and I have only had this vehicle for a year from a dealership. I feel it is unsafe to drive as the vehicle does not always register that it is in park. I can feel the transmission slipping because of this. I would really appreciate some support for this. It is a 2019 GMC Acadia, which is also apart of the other vehicles that are apart of a lawsuit in Ohio and other states. This is a safety hazard for myself and my family.

The transmission keeps slipping, clunking, and not shifting correctly. Not shifting or down shifting correctly up and down hold or at stops. My husband is a trained mechanic and has confirmed through his place of employment that the transmission is failing. It hasn’t no yet been inspected by the manufacturer, police, insurance. No warning lamps, but the transmission temp rises to 270F+ In regards to the next question.. the issue is ongoing.

Shift to park issue car is in park car is not recognizing it and won’t turn off accessories

1. What component or system failed or malfunctioned, and is it available for inspection upon request? The issue was with the gear select switch and jumper harness, related to the "Shift to Park" malfunction in my 2019 GMC Acadia. Yes, the components were available at the time of the repair with the GMC dealer. 2. How was your safety or the safety of others put at risk? The vehicle would not recognize when it was in "Park," which prevented it from being turned off. This could lead to unexpected vehicle movement or battery drain, and creates a safety risk if the driver assumes the vehicle is secure when it is not. It also poses a hazard if the vehicle cannot be safely shut down in an emergency or in unsafe conditions. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the issue was...

On my 2019 Acadia, the message shift to park keeps appearing on my dash when I shirt the car into parked. It's getting more frequent and when I called GMC it's a well known problem to where the lady taking my appointment says yes we are aware it's happening alot. They want to charge 800 to fix a problem that should be a recall. It's a well known problem and there has been cases and suits brought up and GMC will not make a recall on this even though the mechanic said I can't believe this hasn't been recalled. Can you help with making GMC do a recall in the Shift to Park. Thank You

Whenever parking the car and trying to stop (shut off) the engine it will randomly say “shift to park” and I cannot shut the vehicle off.

When I park and then turn the car off the car fails to recognize that the gear shifter is in the park position. As a result, the car doesn’t fully shut down, leaving the engine running or the electronics active. This drains the battery. I have seen this issue is recalled for other 2019 Acadias but don’t under why it is not recalled in mine. I’m afraid I’ll be out and about and unable to turn my car off resulting in a dead battery and being stranded.

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.

Check engine light comes on, temperature gauge stops working, driving assist reduced notification, engine fan runs on high only. Temperature gauge and sensor were replaced 27,000 mi ago when this happened before.

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.

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

Shift to Park message, and chime remain on after car shift handle is already placed in Park. Car rolls. Ongoing problem/defect well documented/reported among other similar units.

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

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

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...

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

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.

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...

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....

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

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...

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.

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.

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

Shift to park. Shows it’s in park but it is not

Intermittent Shift to Park Message Displayed While Vehicle in Park,DTCB000ASet. Known problem and service bulletin issued but no recall has been issued. Second safety problem Safety features disabled, unknown reason why.

Our 2019 was repaired back in 2021 for a "shift to park" issue. This same issue is happening again after 2 years of being repaired. We see that there is a major issue with GMC vehicles and there have been recalls for this same exact issue. GMC Coleman, Lawrence NJ is refusing to fix problem under a recall. We would like this to be covered or reimbursed.

Yes, my vehicle is available for inspection upon request. When I go to put my 2019 GMC Acadia in "park" the shifter states it is in park & the dashboard shows it in "P." However, when I turn the vehicle off, an error message comes up reading "shift to park" and my car wont fully shut off. You can feel the car move forward or backwards a tiny bit (depending where vehicle is parked). This makes me have to turn the vehicle back on, shift into "drive," back into "park," and then shut the engine off and pray the "shift to park" display doesn't come up. This process was repeated this morning when I arrived at Walmart 3x before it finally shut off, then when I got home it happened at least 8x before I could safely leave my car in my garage without the worry of it not truly...

Driver side blind spot not longer works. When driving the blind spot indicator just stopped working a month ago and I didn't take notice until I almost hit another car. I contacted gmc about this issue as well and was also told there isn't any recall for this and it would have to be diagnosed by there mechanics. There were no other issues prior to this. Also the "shift to park" warning has been popping up for 3 days now when my car is in park. My car won't complete shut everything off until that warning is turned off. I called GMC of puyallup and was told only certain vin qualifies for the recall for the gmc 2019 acadia. That's absolutely ridiculous! I can't exit my vehicle until the car senor knows my vehicle is in park which is a major concern and safety issue because my home is on...

My GMC is in the repair shop for the alert (shift to park). I was once again unable to turn off my car and place it safety in park. This is a known issue and GMC Dothan states the 2019 GMC Acadia with my vin number is not on recall?? This is a know dangerous safely issue.

I have a 2019 GMC Acadia with 59051 miles on it, I get regularly oil changes and maintenance but it’s need a transmission. How is this? The mechanic tells me that there is no ETA when one will be available when he called to get one. This lets me know that there is a problem with the transmission and they probably should have a recall.

Unknown 3rd brake light leaking water inside. Health Concern due to mold.

The part broke on my vehicle. Part is on national backorder. I'm expected to be without a vehicle til mid December. I was told no one in the state of Louisiana has the part. This has to be affecting a lot of vehicles if this is true. I love my GMC and I hope they make this right. Radiator surge tank inlet hose is the GM part.

When putting vehicle in park, it doesn’t always sense it is in park. Will sometimes have to move it back and forth for a couple of minutes.
