2018 GMC Acadia ELECTRICAL SYSTEM,UNKNOWN OR OTHER

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

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 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.

Had to replace the shifter, harness, and parking assist module to the tune of $1569.00! When it was put into park the system would not acknowledge it was in park...therefore I could not lock the vehicle and an alarm kept going off. My Acadia only has 12,000 miles on it...NO excuse for having to replace those parts with or without a warranty! Dealership said I am not the only one this has happened to...they have replaced a number of them!

Shift to park notification keeps coming on after shutting off the car. It obviously has been shifted in to park before turning off the engine, but the notification keeps popping up. I have had the shift harness replaced by a mechanic once alreafy. He says this is the GMC authorized fix. IT DID NOT FIX THe PROBLEM! Of course, he'll put another shift harness for me, but what are the odds that will solve anything. GMC needs to come up with a better solution! It is frustrating and time consuming trying to come up with whichever trick will work to make the notification to away. I am not a very happy customer!

EVERY TIME I PARK AND TRY TO SHUT CAR OFF THE CAR REFUSES TO TURN OFF AND GIVES A MESSAGE THAT SAYS SHIFT TO PARK. REQUIRES 20+ ATTEMPTS OF RESTARTING, SHIFTING OUT OF PARK AND BACK INTO IT BEFORE SUCCEEDING. CAR IS CLEARLY IN PARK, NOT ROLLING BUT I'M UNABLE TO TURN OFF CAR FULLY. THIS HAS BEEN OCCURRING THE LAST MONTH OR TWO. I BOUGHT THE CAR BRAND NEW.

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 CARE 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.
