When putting my vehicle in park and pressing the engine off button, I get an error message "shift to park", and the vehicle beeps and will not turn off the electrical, but the car is already in park. I am unable to turn off my vehicle completely. I have to press start again and put the car in reverse and back to park, sometimes multiple times in order for the vehicle to register that is in park and allow me to shut off my vehicle completely. I am concerned that the vehicle may not actually be in park when I put it in park. I do not want it to roll down a hill and I want to be able to turn off my car without being concerned it will continue to run electrical and kill my battery.

I just bought this 2018 Acadia in July and it is now giving me the shift to park alert even though the car is in park. It takes several tries of restarting and shifting to get it to turn off, so far. I'm afraid one time it will be stuck there permanently.this apparently is a known and frequent issue and GMC needs to do a recall.

2018 GMC Acadia VIN [xxx] my car has 41,000 miles. When I park and try to shut my car off a message pops up that says "shift to park". it will not allow me to shut my car off because it does not identify that it is in fact in park. Today it took me 15 minutes of turning my car off and on and shifting in and out of park to get it off. Two days ago my car started to roll backwards as if it were in neutral. This is a serious safety hazard and needs to be recalled! information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

GMC Acadia "shift to park". the SUVS fail to detect when the gear shift lever is moved to park. The dash board showa a message on the instrument clusters that says shift to park even though the gear shift levers are already in park. In addition to losing the ability to shut off and lock the SUVS, I was unable to turn the SUV off after attempting to do so serveral times.

1* purchased March 2018 (Acadia denali) since August 2018 in motion when I accelerate it sounds like a loud lawnmower & crackling sound in rear muffler area. Took it Chevy place in glenpool, ok. They couldn't find anything. 2* on 2 occassions, in motion, the car accelerated with a loud noise & as if it were getting power & not moving then jerks & speeds up about 15mph faster & I couldn't stop it. I kept slamming on my breaks, but the break would only go in so far. I was frightened with my 2 young boys in car screaming. It's like riding a horse & it takes off & you can't control it. 3* on about 8 or 9 occassions stationary I get out of my car & it makes a really loud annoying sound like a machine/robot powering down. My kids always say, it's going to blow up 4* the most annoying, for past month...stationary, every single day & time I turn my ignition off. It has loud beeping sound & check rear seat flashing on screen then shift into park flashes. This occurs every single time I turn my car off. Sometimes I have to just let it go on all day because I can't get it stop. I turn car on & off shift back & forth & it still will not go off. Sometimes it does after long periods of time. I don't have time to struggle with getting a car into park every single time I turn my ignition off. I have to beat it forward hard with my hand to the point my wrist is bruised. Now I have to use my foot to kick gear shifter into park. I'm afraid T's going to roll out & or down and hit something, someone or even one of my children. Which would not be good. I've seen several of same complaints. This really needs to be investigated & recalled asap. My elderly mother had to call my brother to another part of town to beat the gear shift into park. This car was brand new & I shouldn't have any of the above mentioned issues. It's frustrating thinking GMC was top of the line & it's not.

"takata recall" I have a 2018 GMC Acadia been having it since July 2018. Today I put the car in park and pushed to the button to turn the engine off and the engine shut off but in the dash it was dinging and said "shift into park". I turned the car on and off several times before it would shut all the way off. It has down it every time I went to shut the car off today. Couldn't leave it at work in the parking lot like that so I had to keep turning the car on and off and shifting it into reverse and back to park until it shut off.

The service stabiltrak notifcation keeps coming on and shutting off on its own while in motion on a street and it has also happened while on the highway. It has occurred at different speeds and several times with different people driving.the dealership can't figure out why and it doesn't show it even came on at all. When in motion on a strret going 46mph the car tried to auto correct pulling me out of my lane by itslef. It was a straight street with no curves where this occurred. Thank god there wasnt a car in the lane next to me. The side mirrors reset themselves all the time. If I move the seat and then hit the memory button so it will go to the set position the seat doesn't move at all. I have had rental cars more than my Acadia the past 2months while the dealership trys to get these issues fixed. I love the car but am getting mad with all these issues.

I purchased the wireless charger. I received the GM document stating what version of phone I needed for the charger to work. I purchased a phone and the charger does not work. The dealer researched the phone and there are only specific models manufactured in the same year that work for the charger. I have tested with 5 different model phones and only one worked. This option is a waste of money and not advertised appropriately nor does the GM brochures or website provide adequate information to notify the consumer of the issue.
