2019 GMC ACADIA Electrical System 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

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.

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”.

Thermostat is repeatedly going bad. Throws Steering Assist reduced. Had it replaced twice and it’s bad again.

The Shift to Park is not recognizing when my car is in park and continues to ding and won’t let me turn my car off.

When parking the vehicle the electrical system will put a warning on the dash indicating you are not in park. A message indicates shift to park. The car will not shut off and you cannot lock the vehicle. This happened when I first bought the vehicle and it was under warranty and repaired. It is now happening a second time in 2025.

When DRIVING the center console screen begins to glitch. It will begin to move around and try to connect to the internet, begin to track navigation, connect to my phone and make calls, or it will just started moving back and forth from the different screens. It also makes sounds while it is glitching. It's incredibly distracting when I am trying to drive. There are a number of online forums that have identified the problem in their same year, make, and model of vehicle. There were no warnings or messages prior to the problem. It presented itself about a year ago and I have just been resetting the battery as a temporary solution.

AFTER PUTTING CAR IN PARK AND TURNING ENGINE OFF, SHIFT TO PARK WILL APPEAR ON DASH- CAR ALREADY IN PARK .

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.

Failure to be in park alarm when shifter is in park. Must play with shifter back into park to stop alarm bells and notice on dash. Supposedly there was a recall issued however not shown on this site per my vin #1GKKNXLS7KZ107842. Very irritating, please advise.

July 31, 2025 Our 2019 Gmc Acadia would not shut off in a parking lot, I was 45 minutes from home. A message on display says shift to park. This is a safety concern as the vehicle might not be fully secured in park, the vehicle won't shut off and will drain your battery. There is an ongoing class action lawsuit related to this issue, alleging that GM has been aware of the problem for some time but has not provided a satisfactory fix according to Lemon Law Auto Fraud. I called the gm dealer and they quoted me $500 to fix this issue.

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

Vehicle's "SHIFT TO PARK" warning is often displayed when vehicle shifter is in PARK and then the engine is turned off. Often takes several attempts to correct the problem by restarting and turning off the engine or by manipulating the shift lever while in PARK. These is a current recall for this issue with the same year, make, and model of vehicle. Checking the VIN against the NTSB recall list shows this vehicle is not included in the recall.

About a month ago when I shifted my vehicle into park and shut the vehicle off, "Shift to Park" appeared on dash display for which I had to restart the vehicle, shift it into another gear and attempt to shutoff the vehicle again. Occasionally this would work but not all the time. Other times when shifting into other gears did not work I had to restart the vehicle, press the shifter button multiple times and then was able to shut the car off with no "Shift to Park" appearing. On 7/11/25, Arrived to work and had to performed the shifting the vehicle into another gear and was able to shut the vehicle off. When I went to leave for lunch, the car would not start at all, check the GM App and it stated "Critically Low Battery". A co-worker helped jump the battery and I was able to start the vehicle. When I went to leave work for the day, the vehicle would not start again with no notification as to why. My co-worker jumped the battery again and vehicle started now with all the system lights on dash staying on and warnings displayed. 7/12/25 Vehicle struggled to start and all system lights were still on. Later in the day, the vehicle would not start and all overhead, dash, display, taillights would not shut off. We jumped the battery and took the vehicle to our local dealer.

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.

Component: Shifter Assembly & jumper harness Safety concern: Can't turn off vehicle - Carbon Monoxide poisoning, physical safety when parking not at home, as I would have to leave vehicle running... Message in dash was present when I brought vehicle to dealer. Dealer also replicated No inspection other than dealer. Part returned to me. Warning message has been coming on for past 60 days or so, progressively getting more frequent I receive a 'shift to park' message in telltale after I have shifted to park. At times, vehicle will not shut off until shifter is manipulated for several minutes. I have concerns that I cannot park vehicle in garage, if I cannot shut it off. GM is well aware of issue, but has yet to recall them. Dealer actually had replacement shifter in stock for a same day repair.. I was charged $778.98 for the repair, and GM's customer assistance center response to me simply was to file a complaint with NHTSA. My wife does not feel safe driving, as there is no guarantee vehicle will turn off. Dealer replicated issue when I brought to dealership. Dealer has replaced part and has them. Warning lights only appeared when problem reared itself, initially began about 60 days ago, but is not occurring on approximately 2 of 3 shut downs.

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)

When I park my car it beeps and says my car is not in park. Many other models of the 2019 GMC Acadia, along with other GM vehicles, may be affected by a "shift to park" recall. This recall addresses a defect where the vehicle may display a "shift to park" warning message even when the vehicle is actually in park, potentially preventing the ignition from being turned off and the key from being removed. This is exactly what my car is doing but they say my VIN is not included in the free fix. I brought my vehicle after it died to a GMC dealership and they said it will cost 1,000 to fix. My safety is at risk because I drive to different locations as a therapist and I often drive home at night in remote locations.

I have had intermittent issue with a message to shift the car to park when I shut it off. It was in park. If I wiggled the shifter it would often correct. That went on for a few years on and off. Lately it was more persistent. I brought it into the dealer and they replaced a harness and a switch. Seems that a harness would not go bad unless it had a manufacturer defect. I have seen a lot of reports on this issue on online blog sites. Seems to be a common problem. The problem with this defect is that when it is sin that mode, you cannot safely secure the vehicle and warning bells keep ringing. So the vehicle cannot be left like that and expect it to be secure.

The contact owns a 2019 GMC Acadia. The contact stated that upon shifting to park(P), the vehicle made an abnormal beeping sound that persisted after turning off the vehicle. The message "Shift to Park" was displayed. The vehicle was taken to the dealer, where an unknown harness and switch were replaced. The vehicle was repaired. The manufacturer was notified of the failure and informed the contact that the VIN was not included in a related recall. The manufacturer referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 39,886.

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.

I would park my car and try to turn off car. The car would not turn off. The car continued to ding the car remained on. The safety issue is the car wouldn't turn off. After many many times shifting from park to drive it would finally park, this happened every time using the car. I discovered the same exact issue is a recall on 2017 & 2018 GMC Acadia our exact car ! Called the dealer explaining SHIFT TO PARK issue. Brought the car to Buick GMC of Mahwah they noted in fact it was SHIFT TO PARK issue. Two days later came in for the car they would not cover problem. Cost $950.00 for exact recall the 2 years prior. Also, contacted GMC corp. they were no help just said had no recall. Our car is 2019 Acadia with 27,236 miles.

Shift to park message when vehicle is in park not allowing vehicle to be shut off

I randomly get a "shift to park" warning even though the vehicle is in park. It looks like there has been this same issue with older years but not my vehicle according to the VIN.

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.

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.

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.

Last week I parked in a large public parking lot and attempted to turn my car off. I received a notification in my dash to “shift to park” even though my car was already in park. I was unable to turn the car off or lock the doors. I ended up having to leave. I have now gotten this message six times in the past week. It can take up to twenty minutes to get the car to turn off so I can exit. Yesterday upon returning to the car I showed an error message as soon as I started it that the parking brake needed service, stabilitrak is disabled and steering assist is disabled- drive with care. As I tried to exit the parking lot, I found it almost impossible to turn the steering week. I pulled over and restarted the car, releasing the steering wheel so I could get home. This morning, all of the service lights were on and periodic warnings flashed on my dash throughout my drive to work. I contacted the dealership and was told that there is a recall for this exact issue on the 2015-2018 models of my car. I have a 2019. This is certainly a dangerous issue that should be proactively fixed and is clearly still present in years that are not being included in the recall. I was told my car was one month past its warranty and told I could pay 250$ for the issue to be assessed and then they could quote me on a fix. The dealership acknowledged that this is an issue they regularly fix.

See attached document for complaint.

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.

The contact owns a 2019 GMC Acadia. The contact stated that the battery, the steering, and the brake warning lights were illuminated. The contact contacted Triple A, who tested the battery, the starter, and the alternator and jumpstarted the vehicle. The vehicle was taken to the local dealer, where it was determined that the battery had discharged and needed to be replaced. The dealer informed the contact that diagnostic testing could be performed after the battery replacement. The contact stated that the battery was replaced four times; however, the failure persisted. The vehicle was not repaired. The manufacturer was notified of the failure and a case was opened. The failure mileage was approximately 3,000.

Mileage: 3,000

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.

The contact owns a 2019 GMC Acadia. The contact stated while the vehicle was parked, she noticed that the engine caught on fire with no warning light illuminated. The fire was put out by the Chicago Fire Department and after the vehicle was inspected the cause of the fire was determined as a failure with the electrical system. A police report was filed with the Chicago Police Department and a report was provided. No injuries occurred and no medical attention was needed. The vehicle was not towed. The dealer was contacted, and the vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 65,000.

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.

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.

My car is saying it’s not in park when it is in park.

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. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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

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.

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. I have had to replace the battery twice in the same year. I have brought this issue to the dealership from the beginning of purchase and was unsuccessful.

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.

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.

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 contact owns a 2019 GMC Acadia. The contact stated that the entertainment center changed and moved through all channels without touching the screen. While in park, the vehicle failed to turn off as desired. The shift-to-park message was displayed. The vehicle was taken to the local dealer, where it was diagnosed that the entertainment center needed to be replaced. The vehicle was not repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 21,000.

Mileage: 21,000

The vehicle would continuously not register as being in park.

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

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.

"Shift to park Warning light" comes on when turning off vehicle when vehicle is in park.

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.

There have been no reported recalls yet my vehicle is on it's third battery since purchasing it? How is this possible?

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.

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.

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’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.

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.

2019 GMC Acadia started producing error code of “shift to park” around 32,000 miles. This malfunction is directly connected to a know a non manufacturer flaw in the shifting mechanism shifter switch an faulty grounding. The error code “shift to park” will not allow you to properly shut off or start the car causing potential safety threats to individuals involved. 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.

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.

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.

The contact owns a 2019 GMC Acadia. The contact stated while attempting to start the vehicle, the vehicle would not start. After several attempts, the contact was able to restart the vehicle however, the vehicle inadvertently stalled. The vehicle was towed to the dealer and the battery was replaced. On another occasion while the contact shifted the vehicle into park, the contact heard a beeping sound coming from the vehicle. The vehicle was taken to the dealer, but the vehicle was not diagnosed. The manufacturer was not contacted. The failure mileage was 28,000.

Mileage: 28,000

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.

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.

The middle buttons in the infotainment system do not work - only the buttons around the edges (top, left, right, bottom) work.

"Steering Assist reduced drive with care" displayed on screen when I was driving. The temp gauge stayed on C, the a/c did not work and engine fan came on full blast. After a couple days of this, it went back to normal. Coolant was checked and full at correct level.

Intermittent shift to park message displays on the dash. Had to turn the automobile back on to start the engine then moved gear selector to drive then to park. At this point the message disappeared allowing me to turn off the automobile.

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.

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

Once vehicle is in park and ignition is shut off, a message will show to "shift in park" when it is in park. When this message appears, it takes several times to shift the car back and forth in order for it to register that it is in park. This occurs occasionally...sometimes more frequent than other times. It just did it today and it hadn't done it in a couple of weeks. The vehicle will not turn completely off or lock until you can get the stick to register it is in park. Sometimes it takes me a second to get the message to go away, other times it takes several mins. Really aggravating! These models are not cheap. This has occurred for well over a year now. I purchased the car November 2019.

After shifting the car into Park and pressing the start button to stop the engine, the message "Shift to Park" appears, and the engine does not shut off. This issue happens intermittently, but it has sometimes taken several minutes of shifting and re-shifting to get the car to turn off.

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 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 HAVE HAD OUR 2019 GMC ACADIA AT TWO DIFFERENT DEALERSHIIPS, RECENTLY WE HAD IT AT THE DEALERSHIP WHERE WE PURCHASED IT NEW IN 2019. THE DOOR LOCKS KEEP MALFUNCTIONING WHERE THEY EITHER WORK OR DON;T WORK AT TIMES. MY WIFE AND CHILD GET LOCKED OUT OF THE VEHICLE WHICH IS A SAFETY ISSUE. THE DEALERSHIPS HAVE WOIRKED ON THE VEHICLE A HALD DOZEN TIMES BUT THE ISSUE IS STILL OCCURRING. THE ORGINAL DELAER NAME IS COCHRAN GM OF ROBINSON IN PITTSBURGH PA. THE DEALER HAS BEEN GREAT WITH US BUT THEY STILL CAN'T FIND THE ISSUE.

"SHIFT TO PARK " MESSAGE STARTED COMING ON THE DISPLAY EVEN THOUGH THE VEHICLE IS IN PARK. ONCE THIS MESSAGE COMES ON, I AM UNABLE TO TURN THE VEHICLE OFF. I HAVE TO KEEP PUTTING THE VEHICLE IN GEAR AND PARK AGAIN SEVERAL TIMES UNTIL THE MESSAGE GOES AWAY. I HAVE VIDEO OF THE ISSUE BUT DONT SEE WHERE IT CAN BE UPLOADED. THERE IS ALSO A CLASS ACTION LAWSUIT IN CONN ABOUT THIS ISSUE.

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.

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

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.
