Our 2017 GMC Acadia denali is experiencing "action required" "shift to park" alert on the dash. The indicator on the dash shows the car is in "P" for park and the shifter is placed into the park position. The only resolve for this error to go away is pushing back and forth on the shifter until finally sometimes up to ten minutes, the system recognized that the car is actually in park. If you do not spend the time to try and make the system recognize that shifter is in the parked position the car will continue to try alert you with dinging inside the car and then honking. This is a known issue to which has been reported by several people upon our investigation after experiencing the problem. The part to which is needed to fix this issue is currently on backorder per our local GMC dealership to which there is no estimated time to receive the part in to resolve our issue. We are being told it could take "weeks" prior to this part being received to fix the issue.
When shifting to park and shutting the vehicle off message displays shift to park. I have had the shifter cable replaced and 3 months later it is doing it again. Obviously there is another issue but GM cannot figure the issue out.
Service side detection system warning came on last year. I took it to dealership since I have extended warranty to cover problems like this. Dealership refused to fix because I had taken a light hit to the rear fender area where the sensor is on 02/06/2016. Friends told me this is a major problem with these vehicles so I looked online and was appalled at the complaints! I am retired and on a fixed income and can't afford the $1,600 or more right now. As a senior this was a reason I purchased this vehicle. Now that it does not work I have to be extra careful with blind spots! this warning came on and function stopped working when car was turned on.
When my vehicle was in park & I was going to turn it off it gave me this message action to park when in park. This has happened several times. I have taken it to the dealership & nothing can be done.
I got this vehicle brand new in 2016 it has approx43000 miles on it. Last Tuesday it would not start nothing worked towed to the gmx dealer they said it was a map light!!!! and it ran the battery down well today it did the same thing I do not believe it was the battery the same day it went out I received a applicaion download, I have no idea what that was. I paid alot of money for this vwhicle and I think there should be a recall before this problem causes death ' the vehicle is still at the dealership-I called to reort this problen to GMC the first evening noting was done either, called GMC ro toe didnt even show

We have had numerous issues with the cars brakes automatically locking up when something triggers the collision safety break. Specifically when crossing rail road tracks after a train has past. As a result the car stops completely and automatically while on railroad tracks and won't allow you to move. You have to put the car in park, wait (on railraod tracks) and then attempt to move but it may activate it again so you have to do it again. Meanwhile you are on tracks, with cars behind you honking and screaming. This has happened numerous times, reported it to our dealer, service and GMC corporate where nothing was done. They said they would put in a "black box" like device but never did. It is a major safety concern for my family and one that GMC is not addressing adaquately.
My vehicle would not unlock for hours then it finally did and ran for a bit. Then when started again would not N. then went to bri G it in and nothing worked correct. The speedometer was at 0 and it was scary! the whole vehicle would not work right and when I brought it in they said it was a side sensor module and it was $735 to replace. My car is not that old. They said wetness could have got to it. We live in min edits. Many cars get wet. That is absolutely crazy. They also told me they share sopose to be coming out with a recall and new boxes that cover these sensors. I will be expecting to be reimbursed when this becomes a recall which it defiantly needs to be! I paid a lot of money for this vehicle. The price of mine should be on this!
Vehicle had multiple (more than 2) warning lights flashing on and off, while RPM and mph needle would fluctuate simultaneously. This would happen while in the driveway and also while in motion. Vehicle would not accelerate with accelerator pedal fully pressed, especially on an incline. While this was occurring I had to exit the highway and turn around in an adjacent subdivision. I could not get out of the way of a car in the neighborhood because I was trying to go forward on the street due to a slight incline. It would also jerk into gear when moving from reverse and drive. Had this happened in a traffic intersection, it would have been deadly. This car is unsafe. After 6 months of being 'fixed' it has started happening again. The dealership has had the vehicle for a week this time without being able to fix it. The last time it was at the dealership for around 10 days.
When car is put into park a 'action required' comes up saying 'shift into gesr' which the vehicle is already in park. Therefore, will not shut off causing the battery to drain and die.
Shift to park error message when gear shift is in park and vehicle is turned off. The auxiliary power stays on (radio and usb) and will not let me lock the doors. This happens nearly every day. Must restart the vehicle and put into gear then into park multiple times.
The A/C comes on and off automatically and you have no control over it. GM states they did this so you don't have to turn your def. On. while I'm driving I continually have to take my eyes off the road to fiddle with the temp. Control. (the A/C comes on full cold) I've contacted GMC and they refuse to do or offer any help in this matter.
When you put the shifter into the park position and you try to turn off the vehicle 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. It beeps incessantly, the battery remains on and the doors do not want to lock. GMC has been made aware of the issue by hundreds of 2017 Acadia owners however their engineers have not found a solution. This defect is forcing me to turn the engine on and off multiple times, trying putting the car in reverse and then shifting back in drive, wiggling the shifter, opening the rear passenger doors and repeating any and all of these processes until it eventually turns off the shift to park message and allows the vehicle to shut down (or if you can confuse the electrical panel and have another message pop up to override it, such as the one that says 'check rear passenger seat". I do not know if my car is ever truly in gear or not. I'm afraid that it might cause a dangerous situation where my vehicle rolls thinking it is not in park or the battery dies unexpectedly or the vehicle is stolen because it will not shut off or the doors will not lock. I bought this vehicle brand new and this started occurring at around 15,000 miles and is a highly reported problem that necessitates a recall fix for safety.
I purchased a new 2017 GMC Acadia on December 14th 2017. On October 11th 2018, my Acadia was rendered completely disabled by a what has been described by the dealership as a " dead battery" I was almost locked in the vehicle because the entire electrical system failed and the electronic locks would not operate. There was no previous indication, notification or warning by the vehicle and monitoring service or of an impending battery failure obviously, a 10 month old battery in a new car should not be completely drained after only 10 months of ownership ( leading me to believe there may be more at play than just a bad battery). Had this happened anywhere else besides my driveway, it would have been a major issue. The vehicle was then towed to the nearest authorized GMC repair facility. The dealership ran diagnostic tests of the electrical system and found nothing wrong, but this still leaves me with doubts about the reliability of the vehicle and integrity of the electrical system.
Shift to park stays on when placing my vehicle into park. This does not allow the electronics to shut off indefinitely resulting in a dead battery. GMC has stated that this is not a recall and that because I am out of my warranty this is not covered. After reading multiple forums there are hundred of people with this same issue from 100miles to 60K+ and GM has refused to make this a recall. Someone did state that they got their shift assembly replaced and it fixed the problem. Very disappointed with GM and not standing behind an issue that is clearly a defect from the manufacture. They also are having the same issues with Cadillac stemming form their Tennessee plant. Buyers beware!
When the vehicle is parked after driving and the placed in park, the vehicle fails to recognize that is in "park". this causes the interior accessories to remain running as though the vehicle is running even when the engine is off. This happens when the vehicle is stationary. From review of information, this is a know manufacturing defect from GM. When GM was contacted to have repaired in the vehicle we were informed that they cannot warranty their vehicles forever and it would not be repaired. This seems to be an inappropriate response for an issue that is not a warranty item but has been published as a manufacturing defect.
