2019 GMC ACADIA Unknown Or Other Problems

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 reproduced and confirmed by a GMC dealer during an appointment on July 22, 2025. They diagnosed the problem and verified that the gear select switch and jumper harness needed replacement. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle was inspected and repaired by an authorized GMC dealer. 5. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No, a "Shift to Park" warning message appeared and the vehicle would not allow me to turn it off without shifting in and out of park multiple times. This first occurred on July 18, 2025, and continued until the repair was made.

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 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.

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 issue with the 2017-2018 Acadia models built in Tennessee.

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.

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.

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 being in park. This has gotten to the point I have bought wheel chalks to put around my car tires because I am afraid this vehicle could roll down my driveway into my neighbor's house or kill some kid playing in our culdesac. I let the last place I was at know & they told me GMC was aware of the issue, but that there was no way to fix it (Auto Revival in Justin, TX). I am unsure as to whether this issue happened for them or not, as nothing was mentioned after being told GMC is aware. That was on January 10th, 2024. No one else has looked at it besides that. It seemed to be occurring less frequently for several months, and then now it is the worst it has ever been.

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 a slope.

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.

The "Shift to Park" error warning comes on even though the vehicle is in park. The vehicle will not turn off. I had this issue with my 2017 GMC Acadia. They tried to fix it once, but it came back. I see in the 2019 version that they have added an audible dinging to the warning. I would have thought after at least 2 years they would have resolved this issue. They just made it more annoying by adding the dinging.

My radio is going crazy. Like going through every radio station, calls people. Its a distraction. And after researching how to fix I noticed thousands of people have the same problem. Almost cause an accident because of the distraction and this is obvious problem in GMC.

My car will not shut off as I am parked and “shift to park” is alerting me. The car keeps beeping. I have to re-start it multiple times and shift it in and out of park for it to finally go off. This last time it took 25 min to shut my car off.

Shift to park sign appears and doesn’t disappear until I turn and off the car multiple times. It’s been retuning problem for the past two months.

When attempting to park vehicle, the alert "Shift to Park" populates and the car will not completely shut down. This happens sporadically and can take up to 15 minutes to get vehicle in the right position to completely park and shut off. If it's not in the proper park position, the car can continue running, battery drainage and possible roll out of place. This also causes issues with the transmission not shutting off. I have not had this particular vehicle inspected, but contact with dealer service departments confirms continued complaints of this issue and it has not been addressed by GMC/General Motors. Problem has been occurring at various times over last 3 years.

During a routine oil and filter change the technician noted that the "rear tow links are excessive play in them." Several GMC vehicles have had numerous recalls to tow links over the years. Dealership suggested the repair and confirmed services were not covered under warranty. After further research into the repair there are countless forums and complaints about GMC vehicles needing tow link replacement. Photos of the original tow links show minimal wear and tear.

Backup camera stays on while driving forward

What component or system failed or malfunctioned, and is it available for inspection upon request? The Infotainment system continuously changes screens without being touched. No matter what screen is displayed, it will change on it's own to various other screens. How was your safety or the safety of others put at risk? While I was driving I was using my GPS via CarPlay and the directions were displayed on the Infotainment screen. The screen started changing to other screens and at one point changed to the back up camera. I was almost in an accident because I was unable to see the directions and frightened and confused when the back up camera appeared while I was going forward on the highway. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, I took the car to the dealership while it was still under warranty and they told me it was due to me using CarPlay and that my iPhone just needed to be updated. I updated my phone and the problem never went away. So now I've stopped using CarPlay and the problem is still occurring. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Only the dealership. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No warnings. The problem first appeared in late 2020 early 2021. I have a video recording of the issue as well. Also when I Google the issue lots of other owners are complaining of the same issue.

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.

I would put my car in park but it would not let me turn the engine off, I would put it back in drive and then park again but it wouldn’t let me turn the engine off. I displayed a message that I needed to put the car in park. I repeated the process and then later it would let me turn the engine off. This happened several times. I took it to my car dealer and they fixed the problem but I had to pay for the repair. They said if there was a recall, they would refund my money. I saw where this same problem was a recall for my vehicle up to 2018. My car is a 2019.

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?

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!! It

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.

There is a shift to park issue. When I place the shifter into park and the car is in park, I turn the vehicle off and I have a message action required “shift to park”

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.

While driving the all the the service lights came on on the dashboard and the system as well as the stabilitrak notification. The car begin to not want accelerate and I had to put on the hazard lights on a drive very slow home. Upon arrival home the car would not start but would not power off either and the a "Shift to Park" warning message is displayed.

Vehicle will have a message on the dash that says “drive with care steering assist is reduced”, the fans will come on and stay on, and the temperature hand will quit working along with air conditioner. It has not been inspected, I am not sure if the steering assist being reduced could cause any harm to myself or others.

Car wont shut off..displays shift to park. Had to turn car off a handful of times before i got it to turn off.

I’m not sure but a warning came on that said steering assist reduced drive with care and my temperature gage and AC weren’t working all of a sudden when it happened

Shift to park message appears post vehicle being in park! Vehicle has been inspected per Jeff Schmidt auto group (formerly Valentine Buick GMC, Inc! I was told shifter needs replaced as well as harness! Very disappointed do to the fact I brought this vehicle in 2019 off the showroom floor and 3 yrs later there’s a problem with my shift gear with 36k miles on vehicle..

When I put my 2019 GMC Acadia in Park shut the car off get a message to put the car in park. The radio does not go off, not able to lock doors. Displays that message. Have to keep putting it out of the park and after 5 or 10 minutes message finally goes off and it will let me lock doors. These last couple days it had done it every time I drive it

When I put Shifter in PARK, the dash indicator states the car is in PARK. I then push the Start/Stop button to turn the car off, but the dash displays car is not in PARK. Sometimes the car will not shutoff or the car just beeps until I push the Stop/Start button. I cannot lock doors to leave the car. When this occurs or when left in this state the battery runs down, which leaves me stranded. This is certainly a safety issue on various levels. It the car really in Park! What if it on a hill and starts to roll into me or someone else.. Scary!!

The Rear Hood was opened to get groceries. All of a sudden the hood came down on my back. I had to push the hood up manually, and tried to close with remote or with button on the hood but the Rear hood would not close. I then had to manually close the hood. On August 11, 2021 I took the car to the dealer and they replaced both Rear Hood Struts that wear leaking fluid. This SUV is only 2 years old with 16000 miles and should not be having these type of safety issues that can potentially be life threatening.

We are experiencing the "SHIFT TO PARK" issue on our 2019 GMC Acadia at 44,000 miles. We have been told we need to pay $200 for the fix PLUS more than $200 for the battery which has undoubtedly been impacted by the first issue. Needless to say, we are not happy that we'll be charged for a known GMC issue and we are aware there are class action suits around this issue in various states. We have been loyal GMC owners, but we are now concerned about the safety issues this presents our family. Ironically, we are searching for a new truck at this time and this recent hardship will impact our brand choice now as well as in the future. Please let us know how this issue might be rectified.

AFTER PLACING MY CAR IN PARK, AND TRYING TO CUT OFF THE ENGINE, IT ALERTS ME TO "SHIFT TO PARK" ... I WILL HAVE TO RESTART MY ENGINE, PUT IT IN NEUTRAL AND THEN BACK TO PARK, AND TRY AGAIN TO SHUT OFF THE CAR. SOMETIMES IT WORKS ON THE SECOND ATTEMPT, BUT USUALLY TAKES 3-4 TIMES OF CUTTING ENGINE OFF AND ON, SHIFTING FROM PARK TO DRIVE TO PARK AGAIN. IF YOU ATTEMPT TO EXIT THE VEHICLE, THE HORN WILL START TO HONK, AND ALARM GOES OFF. THE CAR IS CLEARLY IN PARK, THE SHIFTER CAN NOT MOVE FORWARD ANY FURTHER, AND THE INDICATOR SAYS ITS IN "PARK" IT IS ONLY AFTER YOU PRESS THE START/STOP BUTTON THAT THE ALARM INDICATES IT NEEDS TO BE "SHIFTED INTO PARK"

FIRST TIME BACK IN JUNE 10TH, 2020, I TOOK IT IN BECAUSE OF "REMOTE NOT DETECTED" THEY COULD NOT DUPLICATE THE PROBLEM, FEW HOURS LATER, SAME DAY AFTER I PICKED THE CAR UP IT WENT HAYWIRE WHILE PARKED. IT THREW ITSELF INTO THEFT MODE, WOULD NOT LET US MANUALLY LOCK THE CAR, ELECTRICAL WAS STILL ON BUT ENGINE WAS SHUT OFF, ALARM, WINDSHIELD WIPERS, AND LIGHTS WAS GOING OFF WHILE I HAD IT TOWED TO THE DEALERSHIP. THIS TIME THEY'VE TOLD ME, THE A/C CONDENSATION FRIED THE CPU MODULE BECAUSE THE ONLY THING KEEPING WATER OUT OF THE CPU WAS A TRAY. SEPTEMBER 9TH, 2020 I TAKE IT BACK INTO THE DEALERSHIP BECAUSE AGAIN THE CAR KEPT READING "NO REMOTE DETECTED". THEY CLAIMED IT WAS MY "DASH CAM" THAT CAUSED THE ISSUE. OCTOBER 14TH, 2020 THE CAR AGAIN WENT HAYWIRE WHILE IN MOTION. THIS TIME IT THREW ITSELF INTO THEFT MODE, ALARM WENT OFF, WIPERS, WAS READING LOW FUEL (FULL TANK) STEERING ASSIST TURNED ON AND OFF, BRAKES STARTED LOCKING MID BUSY STREET, STEERING WHEEL TIGHTENED ALSO. I BARELY COULD TURN IT INTO A NEIGHBORHOOD STREET TO GET OFF THE ROAD. I HAD THE VEHICLE TOWED BACK TO THE DEALERSHIP AGAIN, THROUGH MY TRIPLE A PLAN FOR THE SECOND TIME BECAUSE I WAS "OUT OF THE AREA" THAT THEY COULD SEND A TOW TRUCK TO. THEY TELL ME AGAIN CONDENSATION GOT INTO THE CPU AND WASN'T EVEN SURE IF IT'LL HAPPEN AGAIN IF I CONTINUE TO RUN THE A/C. I PICKED THE CAR UP THE NEXT WEEK AND ON OCTOBER 25TH, 2020 THE CAR AGAIN WOULD NOT READ THE KEYS. EVERY INCIDENT BUT OCTOBER 25TH, 2020 INCIDENT, I HAVE LET A SUPERVISOR FROM GM KNOW OF THE SITUATION, HIS NAME IS [XXX] EXT. I HAVE RECORDED EVEN PHONE RECORDS OF EVERY INCIDENT THAT'S OCCURRED.

AFTER JUMP STARTING CAR BECAUSE OF DEAD BATTERY DECIDED TO DRIVE TO DEALER 1-2 MILES AWA.Y. MY WIFE FOLLOWED ME IN CAR. WHILE DRIVING DURING THE 1-2 MILE TRIP THE STEARING WOULD LOCK UP (QUIT WORKING) AND THE BREAKS AS WELL.THIS LASTED SEVERAL SECONDS AND RESULTED IN TOTAL LACK OF CONTROL AT 35-45 MPH ON A CITY STREET. THE ALTERNATOR WAS WORKING PROVIDING ELECTRICITY TO THE CARS SYSTEMS. AS BATTERIES FREQUENTLY FAIL I BELIEVE THIS IS A CLEAR AND PRESENT DANGER TO THE OCCUPANT AND OTHER VEHICALS ON THE ROAD.THIS OCCURRED ON SUNDAY OCTOBER 17, 2020

I HAVE HAD FADING ON THE PLASTIC AROUND THE WHEEL WELL, THE HEAT WILL CHANGE TO COOL AIR WHILE DRIVING WITHOUT ANYONE CHANGING IT. THE A/C WILL GO FULL BLAST ON IT'S OWN AND THEN ALL OF A SUDDEN CHANGE THE FAN SPEED WITHOUT ANYONE TOUCHING IT. THE DEALER HAS TOLD ME IT WILL ADJUST ITSELF BY 10 DEGREES, NEVER HEARD ANYTHING LIKE THIS BEFORE. THE FADING PART THEY JUST PAINTED OVER IT AND THAT WAS THE FIX. THERE ARE LINES IN IT NOW AND THEY DID NOT PAINT THE ENTIRE PIECE SO IT DOES NOT LOOK RIGHT. THIS CAR IS PARKED INSIDE WHEN HOME, THIS SHOULD NOT HAPPEN. I HAVE HAD THIS CAR IN THE SHOP WAY TOO MUCH SINCE I BOUGHT IT WITH DENTS HAPPENING ON PARTS ALL OVER. I DRIVE TO WORK AND BACK MOSTLY. 2 DENTS HAVE HAPPENED IN THE DEALER LOT WHEN THEY HAD IT OUTSIDE WAITING ON REPAIRS. WOULD NOT BUY IT AGAIN.

I HAVE EXPERIENCED ISSUES WITH THE SHIFTER OF THE VEHICLE TWICE NOW AND IT HAS RESULTED IN REPLACING THE SHIFTER AT LEAST ONCE. 6 MONTHS LATER AND AFTER AN INITIAL REPLACEMENT THE SHIFTER HAS GONE OUT AGAIN. THE SHIFTER REFUSES TO MOVE OUT OF THE PARK FUNCTION. PRIOR TO THE SHIFTER GOING OUT THE CAR WOULD SAY SHIFT TO PARK EVEN THOUGH THE CAR WAS ALREADY PLACED IN PARK. I BELIEVE THE ISSUE TO BE AN ELECTRICAL PROBLEM. THE MIDDLE SEAT BELT IN THE SECOND ROW OF THE VEHICLE HAS ALSO STOPPED WORKING. *TR

I TURNED THE CAR OFF AND IT DISPLAYS A MESSAGE 'SHIFT TO PARK,' EVEN THOUGH THE CAR IS IN PARK. IT DOESN'T ALLOW THE CAR TO SHUT OFF COMPLETELY. THE ENGINE TURNS OFF, BUT THE ELECTRICAL STAYS ON. WHEN WE TRY TO DRIVE IT, IT IS SLOW TO ACCELERATE AND THE RPMS SHOOT TO 4 AND DON'T GO DOWN UNLESS BREAKING. FINALLY THE CAR WILL NOT ACCELERATE PAST 55MPH AND THE RPMS STAY AT 4, WITH THE ENGINE BEING VERY NOISY. THIS LEFT US STRANDED AN HOUR FROM OUR HOUSE BECAUSE THE VEHICLE IS NOT SAFE TO DRIVE. FORTUNATELY THIS OCCURRED IN A PARKING LOT. WE DROVE A FEW MILES TO TRY TO GET TO OUR DEALERSHIP, BUT DID NOT FEEL SAFE DRIVING.

MY MOTHER HAS BECOME TRAPPED TWO TIMES DUE TO THE LOCKS ON THE VEHICLE NOT WORKING. THE ISSUE ONLY HAPPENS WHEN IT RAINS. I TOOK THE VEHICLE TO THE DEALERSHIP AND THEY SAID THEY REPLACED SOME KIND MECHANISM AND THAT EVERYTHING WAS GOOD TO GO. IT RAINED AGAIN YESTERDAY AND MY MOTHER WAS TRAPPED IN THE VEHICLE AGAIN. THIS HAPPENS ANYTIME YOU TRY TO ENGAGE THE LOCKS, I.E. IN PARK, PUTTING IT IN PARK, PUTTING IT IN DRIVE, USING ONSTAR TO LOCK OR UNLOCK, USING THE GMC APP TO LOCK OR UNLOCK, USING EITHER KEY FOB TO LOCK OR UNLOCK, TRYING TO LOCK OR UNLOCK IT MANUALLY.
