2018 GMC Acadia

Shifting to park and vehicle stating the vehicle is not in park, won't let me turn the vehicle off. Transmission going out, brought to many shops letting me know that the transmission is not working properly but won't give an engine light if anything is wrong with vehicle, Wont show on readers what is wrong with vehicle. Electrical, Doors will automatically lock and unlock most times lock and locks me in the vehicle having me have to climb through the windows and having to leave my windows open or locks me out the vehicle and can only get in by climbing in the trunk. Testing has been done and brought to GM to figure out the issue, and they replace the computer in it but still has the problem. I have had shops tell me these are all huge issues that needs to have a recall because my vehicle is not the only GMC Acadia that does all this. How is any of this safe for me and my kids.

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.

When I put my vehicle in park, the message “shift to park” pops up. It has been doing this for well over a year. I have already had to replace a battery once due to this because I didn’t realize it was still on. It does not happen everytime I park but at random times. The more it happens, the longer it takes for it to go off. At this point, I can only hope my car is really in park. I jiggle the shifter, hit the “ +|- “ on the shifter and have to turn the vehicle off and on about five or six times. Eventually it will go off. It took me 20 minutes today for it to go off in 100 degree heat. The vehicle’s AC is not running when trying to get the shifter to go off. It keeps the electronics running but not the AC. I keep waiting to receive a recall on this vehicle because of this issue but still nothing. I have noticed there is a recall for this but not vehicle. I have already replaced one battery due to this issue and do not want to continue to replace batteries and worry if the vehicle is really in park or not.

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 !
