2017 GMC Acadia

Previous complaint of Shift to Park on 06/13/19 VOQ 11219862 at mileage 36270. On 12/5/21, approx miles 62099 same problem with Shift to Park. Was scheduled for service on 12/06/21 at Adams Buick GMC in Richmond, KY and mentioned the problem and previous complaint. Was told that it had been over a year ago but that they could fix it and charge me $152 for part & $315 for labor. It was less that 26000 miles driven since the last issue. After last complaint, the dealer contacted GMC and the part was replaced at no cost under bulletin for concern # 5 145420 and they replaced the transmission control assembly. This is an ongoing problem with GMC and I don't think that every 26000 miles I should have to pay to replace the same part when GMC knows it is a problem by the numerous complaints. In fact while I was getting my vehicle serviced, I spoke to another lady there who had the same problem with her vehicle. Had I not caught the message, I probably would have had to replace my battery or my vehicle could have rolled into the house. There were no warning lamps or messages prior. GMC needs to step up to the plate and issue a recall because they have numerous vehicles with the same problem. My vehicle has undergone this malfunction twice and I find it unacceptable and know that I can't afford to pay $467 every 26000 miles for an issue that GMC is clearly aware of but won't address because no one has been killed by the issue as of this date to my knowledge, but it's going to happen sooner or later if the issue is not addressed properly.

Vehicle is a 2017 Acadia Denali with ~39,000 miles. The problem started without any symptoms or warnings in October 2021. The dash gives a "Shift to Park" message when the shift is moved to the Park position and the driver attempts (to turn all systems off so as) to park and exit the vehicle. When the Off button is pushed, the "Shift to Park" message displays. The engine does turn off, but the lighting, radio, etc. stay on. When opening the door, the vehicle emits tone(s) suggesting the driver is trying to leave the vehicle while it's running and/or has left electrical systems on. Driver is actually attempting to simply turn everything off and park the vehicle. The fact that all the lighting and radio stay on runs down the battery, potentially leaving the driver stranded.

Shift to park light came on when I parked. As I parked, the break pad locked and I could not release it. The shifter locked and I could not release it. It Would not let me turn vehicle off. I had to experiment on how to get error message to stop and breaks to unlock so I did result to jiggling the shifter And put car in reverse then in drive and park again and trying to turn off (after doing this atleast 4 times) eventually it unlocked and let me turn car off without getting this error message. This happened 2 years prior and I had my 1 yr old in car with me panicking bc I couldn’t drive my car for a bit until the mechanism decided to start working again. This time I knew how to fix it better bc it had happened 2 yrs prior so I knew to wiggle the shifter and try to put it back in drive etc to eventually get car to shut off. There’s records of this shift to park being fixed in 2019 and again in 2021. I should not be responsible for paying ANYTHING for these issues. It is a GMC malfunction. Although mechanical it is a safety concern of mine too!

Vehicle was purchased used in June 2020 ISSUE #1 After shifting car into park, display will indicate P for PARK , but also says vehicle is not in park. Since you are not sure if it actually in PARK and to eliminate this display, you need to restart the vehicle, go thru the gears again and then back into PARK. This happens several times a week with having to restart and PARK again up to 10 TIMES before the vehicle will register it is in park. I have read there is a Technical Service Bulletin on this issue as well as a case to get GMC to issue a RECALL. This is a serious issue because you are unaware if the vehicle transmission is actually in PARK. Having to restart and continually shift to park is time consuming and quite frankly a nuisance. At this point in time, the only way of correction, other than RESTARTING UP TO TEN TIMES, is to click the gear shift several times after placing in park. This will work 5/10 times. ISSUE #2 - Vehicle does not always detect remote. Have replaced battery in remote 5 times and will last approximately 8-10 weeks. At times, when the vehicle has been driven and is placed into park, the display will read NO REMOTE DETECTED. Have also placed remote into pocket into console and will still receive the same NO REMOTE DETECTED. Although there is never any indication battery is low or dead on remote, this is also the only possible correction we have found. However, we do believe there must be another correction for this issue.

This vehicle has twice had parts replaced for the "Shift to Park" issue detailed in GM TSB 19-NA-206. The first incident was in April 2019, and it was repaired under warranty at about 24,800 miles. The second incident was this past week at about 50,800 miles, and this repair cost almost $800 to fix. I contacted GM customer support and was told that I could not get any reimbursement because there was no special coverage or recall for this known problem. This is completely unacceptable, since the problem is clearly a defect in parts manufacturing or assembly, and it renders the vehicle completely unusable since it is impossible to turn the car off when the car does not recognize that the shifter is in park. This is a safety issue because the driver needs to be certain whether or not the vehicle is securely parked before leaving the vehicle.

When you put the car in park it often won’t recognize it and will display a message on the console stating “shift to park”. When it does this you’re not able to turn your car completely off so you just have to continue messing around with the shifter or turning the car back on again by pressing the break until it finally goes off. This happens at least once daily and can take upwards of 5 minutes sometimes to finally recognize the car is in park so you can turn the car off. We’ve tried leaving the car running before when this message is displayed when it’s been parked in our garage thinking it would eventually realize it’s in park and shutoff but after 10 minutes of running it still hadn’t recognized it was in park. We called our dealership about this and they told us that they get a lot of complaints about this issue.

SHORTLY AFTER I PURCHASED MY ACADIA IN MAY OF 2018, IT STARTED DISPLAYING A SHIFT TO PARK WARNING WHEN I WOULD PUT THE CAR IN PARK. I CONTACTED THE DEALERSHIP AND THEY SAID IT WAS A KNOWN ISSUE AND THEY HAD TO REPLACE THE SHIFT ASSEMBLY. WELL ABOUT 3 WEEKS AGO IT STARTED DOING IT AGAIN. ONLY THIS TIME IT'S WORSE. IT TAKES SEVERAL TRIES AND TRICKS TO GET THE CAR TO RECOGNIZE IT'S IN PARK AND ALLOW ME TO SHUT THE CAR OFF - WHEN THE WARNING POPS UP IT WON'T ALLOW THE CAR TO POWER OFF SO ALL THE ELECTRONICS STAY ON. I CALLED THE DEALERSHIP AND THEY TOLD ME BECAUSE MY EXTENDED WARRANTY EXPIRED AT 79,000 MILES AND THEY HAD ALREADY REPLACED THE SHIFT ASSEMBLY ONCE THAT THERE IS NOTHING THEY CAN DO AND I WILL HAVE TO PAY OUT OF POCKET FOR THIS REPAIR EVEN THOUGH IT'S A WELL DOCUMENTED ISSUE WITH THESE VEHICLES.

THE VEHICLE GIVES A 'SHIFT TO PARK' WARNING ON DASHBOARD AFTER VEHICLE IGNITION BUTTON. THIS WARNING SHOWS UP EVERY TIME THE VEHICLE IS ACCEPTED TO SHUT OFF. IT TAKES SEVERAL MINUTES AND TRIES TO GET THE MESSAGE TO GO AWAY AND THE VEHICLE TO COMPLETELY SHUT OFF. THE ONLY SUCCESSFUL WAY OF GETTING THE MESSAGE AND VEHICLE TO COMPLETELY SHUT OFF IS BY WIGGLING OR SHAKING THE GEAR SHIFTER UNTIL IT GOES AWAY. I HAVE BEEN STRANDED WITH CHILDREN IN THE VEHICLE FOR CONCERNS THAT THE VEHICLE WILL ROLL WITH THE VEHICLE NOT REGISTERING THAT IT IS IN PARK. AFTER RESEARCHING THE VEHICLE ISSUE FURTHER IT HAS BEEN FOUND THAT OTHER OWNERS WITH THE SAME YEAR AND MODEL HAVE HAD THE SAME SHIFT TO PARK MESSAGE AND HAVE HAD THEIR VEHICLE ROLL ON IT'S OWN. THE VEHICLE HAS GONE TO THE DEALERSHIP TO BE FIXED BUT UNFORTUNATELY BECAUSE MY WARRANTY HAS EXPIRED I AM BEING HELD RESPONSIBLE FOR PAYING TO FIX THIS SAFETY ISSUE.
