2018 GMC ACADIA Unknown Or Other Problems

I have been having issues with shift to park message for a yr now and it just gets worse and do not have the funds to pay for it myself bu5 see that it is a recall and gm is covering cost for other makes models of my same yr for same issue takes sometimes 20 minutes to mess with my shifter until I can finally park my car where it shuts completely off. This is a safety risk as 1 it could roll away if it isn't 2 my car could drain and die leaving me stranded by not turning off fully one time. This is ridiculous I called gm and all they just pushed me off I don't understand how this is not being taken serious especially knowing this is a known problem!

I continue to get a message "Steering assist is reduced drive with care " this appears to be a very common issue with my vehicle model. it is very expensive to fix. I am just outside of warranty so it is not covered. Online indicates this is so common. It is the vehicle thermostat and sensor prematurely going bad

I have owned this vehicle less than 5 years and it has had the "Shift to Park" error 3 times and has now been replaced 3 times. The 2nd time was in August 2023 and yesterday it had to be replaced again. I don't understand how a part can fail this rapidly when the vehicle is only being driven approximately 10,000 miles per year. It only has 82,445 miles. I would like for GM to issue a recall for this issue or advise who the manufacturer is of the Switch part number 84955381 and Harness part number 84733196. The parts are not that expensive but the labor to replace was $ 462.50 and total parts was $ 55.56 on the invoice yesterday. As this is an ongoing issue I would like reimbursement. I am widowed and living on one income.

For the past 2 years I have been having a problem with the Shift to Park. It causes my vehicle to not turn completely off therefore draining the battery completely, I have gone through several new batteries because of this issue and has left me stranded needing to uber to purchase a new battery. Recently it started causing issues with my vehicles Antilock braking system and the stability control system although I don't know if they are all related but it is causing a hazard to drive around and it it the only vehicle I own.

My Acadia has the shift to park default it has been fixed 3 times and now it is popping up again for the 4th time which means I can't turn my vehicle off it takes forever to get it to go off please help please help

The shift to park in my 2018 GMC Acadia was faulty. On many occasions and randomly, the car would be in park but would not turn off, saying I needed to shift it to park in order to turn the car off. This has left me unable to turn my car off resulting in dead batteries and missed appointments and being late for work. This defect is well documented by GM in TSBs PIT5616A, 18-NA-297, and 19-NA-206, which describes the exact symptoms and repair that I had to have completed. This problem has been on going and as a teacher I cannot continue to be late for school because my car, though in park, would not turn off. Given GM’s prior acknowledgement of this defect, I believe reimbursement is warranted. I have never been notified of a recall on this.

My 2018 GMC Acadia has had the "Shift T Park" alarm and indicator going off after my car is turned off and in "PARK" It only happens intermittently, but frequently enough to be annoying. The dealer and GM told me because my VIN wasn't in their recall range, they would not honor the recall. This has been happening since I purchased the car in 2018.

Battery saver ignited comes on and and the entire dash flickers and turns off ! This happened in a middle of an intersection and I could move my car. We jumped it and went to the nearest auto zone replaced the battery . It was pulling 89 amps . The next day it popped up again and we replaced the alternator. Upon replacing this there was oil everywhere! And we don’t know where it is coming from . Now shift into part light comes on !

Faulty shifter assembly (shift to park) car stays on while in park because of this issue

The shift to park notification keeps coming on everytime we go to put the car into park. It takes about five to ten minutes shifting back and forth to get the car to shut off.

My Acadia car has been having some problems with the shift to park. I put my vehicle on park and my doesn't turn off because it keeps saying that it hasn't shifted to park. Do to this issue my battery car has been draining and my family and I got locked in. I bought the car not to long ago and it's been an issue ever since its getting worse as time has past. I'm really wanting this fix as it can take hours to turn the car off.

My 2018 GMC Acadia is experiencing an issue with the "Shift to Park" feature. When the vehicle comes to a stop and is put into park an alert comes up on the dashboard says "Shift to Park" even though the car is fully parked. This keeps the vehicle from being able to be turned off. Often times this issue is not fixed by turning the car on and re-shifting to park and i have to drive the vehicle and try again. This happens over 50% of the time I try to park this vehicle.

My car will not recognize when it is in park. The shifter will say park but the panel says on and all accessories are staying on. It started out doing it every once in a while but now it does it nearly every day. At work I have had to just leave it like that in the parking lot to keep from being late for work and the accessories stay on. Once I had to call for a jump start after work because my battery was dead. I’m not sure if it can be stolen or not when I have to leave it like that but I don’t think it could possibly be safe. And I can’t afford to call for jump starts all the time. Thank you and please help.

Shift to park msg appears randomly causing the car to not completely turn off even though car is in park. Have to turn car back on and shift to drive back to park couple of times before msg goes away. I see so many people with the same problem why isn't there a recall this is a safety issue. The 1st time my warranty covered the repairs , 2nd time around I have to pay of pocket.

The shifter, the shift to park displays and dings and stays on the dash after I've put it in park and turned off the ignition. It started the first of 2024 and has gotten worse and now it's almost every time.

Having shift to park warning and dinging after shifting the car into park and turning off the car. Cannot leave the vehicle. Then can’t move the shift lever so have to start the car And attempt to shift car into park again which does not always allow yu to shift to park and leave the vehicle again. If this is such an issue why is there not a recall? I have read many articles online about this issue.

Car has started displaying a "shift vehicle into park" message when I have put the car in park. Even though the care is clearly in park this warning displays and I'm unable to turn the vehicle completely off. Have re restart and mess with the shifter several times in order to be able to turn the vehicle off and lock the doors.

Roof is leaking in vehicle without reason after seals and tubing replaced. Brakes lock up without warning!

When I try to cut my car off, it says "Shift to Park", but the car is in Park. Sometimes you can push the gear shift up hard and it will make the light go off, but othertimes nothing works and the car stays running and you can't get out. This is an ISSUE on lots of models and some even have recalls. Why are thy not recalled? I have to leave my car unlocked and running until it decides to turn off. Now I am stuck having to pay for this out of pocket, when GMC knows this is an issue.

SHIFT TO PARK alert popping up on. Car will not turn off.

Vehicles does not recognize when the vehicle is parked and does not allow for vehicle to shut off. Gives shift to park error. Takes several tries for vehicle to recognize it is parked. Same issue in 2020 which was repaired by gmc since vehicle was still under warranty. Now that it is out of warranty it's my responsibility

Vehicle will not shift to park- The cars engine is off and will not turn on, while the car physically will not turn off. I have to move the shifter until vehicle recognized it was in park. resulting in me getting stuck in my vehicle. Multiple reports from other owners with no fix provided by GMC.

The transmission was failing to shift and jerking me forward in the vehicle. The check engine light came on. I was on the highway going at high speeds. Also, my vehicles Internet connection dropped. I pulled off the highway and turned off my vehicle. While starting my vehicle again and attempting to go into reverse, it would not reverse and it would not drive forward . It would just rev the RPMs. My vehicle has been sitting at the dealer for two weeks. They have not looked at it yet. The police were not called as there was not an accident, thankfully. The warning light came on as the vehicle was failing.

Shift to park error notice comes up on dash when car it turned off and in park. Car is clearly in park, but error code “shift to park” appears on screen. Beeping occurs until car is turned off and shifted to R or D and then shifted back to park and turned off. This error happens several times a week, including twice today 6/22/24. I have to restart my vehicle and shift it to R or D then back to park SEVERAL times before the error is cleared.

GM has acknowledged that there is a "Shift to Park" problem with 2017 and 2018 GMC Acadia's. This design flaw/ part failure does not recognize that the vehicle is actually in "Park" so you cannot shut off the engine. In addition, the dash lights remain on which eventually drains the battery. Sometimes the car will roll as if it's in Neutral. GM is very aware of this problem. However, they do not have a permanent solution. GM should be required to issue a nationwide recall to correct the situation by totally disabling the electronic part. In six years of ownership, I've encountered this problem 3 times: 5-14-19, mileage 13,266, 1-27-21, mileage 29,381and most recently 5-30-24, mileage 65,057. This 3rd repair cost me $721.88.

Shift to park warning when I’m in park when I turn off vehicle

We purchased this vehicle New in 2018. Gear Shift Problem. The vehicle displays a persistent “Shift to Park” warning on the dashboard. This usually occurs even when the gear selector is in the “Park” position and I have difficulty in Turning Off the Vehicle. The ignition remains active despite the gear selector being in “Park.” We have to go through all the gears - Drive - Neutral then Park then try to turn it off over and over. May take 5 or 6 tries before I can leave the car safely. Unintended Vehicle Movement: We believe the car is safely in the “Park” position and have exited the car and then it rolled. We have to jump back in and try to turn it off. I'm [XXX] and husband [XXX] and this is causing us injuries. It rolled one time and hit the Handicap Parking Sign in my parking space....

Car does not recognize it is in park and has rolled into my garage door even though the shifter has been placed in the park position. Also it continues to alarm to "Shift to Park" and has caused 2 dead batteries.

4 years ago I would get a shift to park error. This meant my vehicle did not recognize that it was in park. This meant that my vehicle would not lock, turn off the radio or headlights. My husband tried to fix it, but it turned out to be a part that only a dealership could obtain. So $500 later my vehicle was fixed. This was a KNOWN problem affecting multiple vehicles/years. Fast forward to the third week of February this year. I again am getting this same error. Took it to the dealership and there is a switch along with a transmission control harness and jumper harness that needed replaced. These parts have to do with the original shifter that was replaced 4 years ago, but of course not covered. So now $668 dollars later my vehicle is fixed. This is another KNOWN issue and my repair paper says...

Leaving work on [XXX], my vehicle started sounding like a loud truck and it started to smoke. I immediately pull over because something smell like it was burning. That's when I call my insurance company to assist me. So, I had it tow to the nearest Mechanic Shop. It was a scary movement for me being along at night. I'm very upset about this had happen to my GMC 2018 Acadia, the Cadillac Converter left is defect. It is not drivable. It's at the shop for least a month. The Mechanic Shop have not received the parts because GMC has a back order. This is to long being without transportation. This is unfair where I continue to pay the monthly bill. Please, I asking to investigate on this matter. I called the Pep Boy Mechanic Shop today and the manager said it still on BACK ORDER. What happen to GMC...

The shift to park displays and will not allow the vehicle to shut off. This is the second time this has happened in this vehicle. I have 63822 miles and repaired this same issue about 20000 miles ago. Looked into it and it appeared to be a common issue in this year and model. Looking for some insight on what if anything can b me done.thank you

Whining noise from rear axle when 4x4 engaged.

The vehicle will not shift into park. This is a common problem with this vehicle, many lawsuits. When you walk away one has concerns that the vehicle is actually in park or not.

Shift to park issue is getting worse. I couldn’t turn my car off for hours today. The recall is still pending for this and GMC is doing nothing after thousands of class action lawsuits and complaints. Keeping my car running for hours on end while in park because it won’t turn off is causing electrical issues and using tons of gas. I have to get with an attorney at this point because I can’t use my car lots of the times because I can’t leave it running and unlocked all day while I’m at work or at the store. It’s a MASSIVE safety issue. GMC needs to take accountability and fix these vehicles. This has been ongoing for 2 years now.

When I put my car in Park and go to shut it down, it is not recognizing that it is in park, and will not shut down. I have to spend 30 plus minutes messing with the shifter to try to get it to recognize it is in park when it is indeed in park. I have to start and stop my car a number of times to do so. There have been a number of complaints for this over the years and NOTHING has been done with this. This can be a costly repair as I have seen results in a new transmission.

When putting my car in park and turn the car off. the car dashboard says to shift the car in park and beeps. I repeatedly turn the car on and off until the car reads it as being in park. or the car will not turn off completely, it will continue to beep, and it will not lock the doors. I have called a GMC dealer about this issue. There is no warning message except to put the parked car in park!

Vehicle does not recognize that it's in park. Once parked a warning comes on telling you to shift to park. The vehicle does not completely shut off because it does not believe that it is in park.

The thermostat stops working and my a/c stops blowing cold air, and driving assist stops and engine light goes on. It is a rampant problem among GMC Acadias with no reason or fix. Please advise.

The vehicle would intermittently display a "Shift to Park" message and sound alert chiming when moving shifter to park position. The car could not be parked until the chiming and message were dismissed by jiggling the shifter, sometimes after a prolonged battery-draining attempt to end the condition.

When turning off engine it displays "shift to park" and won't shut off. This has been ongoing since I purchased vehicle but is much worse now

Vehicle does not shut off when shift to park. Must put vehicle in gear then shift to park numerous times in order to get the vehicle shut off. Vehicle will not start. Requires numerous attempts applying brake to start

After shifting to park a message comes in screen that is telling me to shift to park I have put it in park so then I have to restart vehicle and move gear shifter back into park sometimes it works on 1st try then sometimes takes extra try’s to get it to clear

Shift to park and unlocked shifter knob, the shifter knob is capable of shifting from drive to neutral without pressing the unlock switch on the shifter while driving. Vehicle says shift to park when parking vehicle, car will not shut off or lock when code is up.
