2017 GMC Acadia

I own a 2017 Acadia Denali (purchased 10-4-17) We started having trouble with the vehicle in that a message appeared saying to shift the car into park. It would shut off but the lights and radio would stay on and you couldn't lock the vehicle. I took it to Ferman GMC in Wesley Chapel on May 28th of 2019. Supposedly they could not replicate the issue. The problem continued and we took it in again on May 31st of 2022. Again, they couldn't replicate what we were encountering. Now it's getting worse, happens almost every time we use the vehicle. So back to Ferman yet again (Oct 12th 2022). Now they are aware of said problem (code is b000a park switch circuit open). At this time they installed an SL-N-SWITCH and N-HARNESS at a cost of $63.13. Then labor, shop fees and taxes brought the total to $760.91, out of my pocket for a known problem. We have also come across a class action suit identifying this as a problem. And a TSB is also out there titled 'Vehicle displays shift to park message on DIC when in park. Vehicle may not shut off when put in park or may not start". There is a NHTSA ID number for this issue: 11353147

The side detection alarms kept beeping regardless of any location on the road or in my own driveway. Now I have a "service side detection module failure" warning on the dashboard. Estimates on repair have been in the $800 range and after having spoken to many GMC owners, several have had the same problem. Some have made the repairs, others have not due to the cost.

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 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.

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.

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.

OUR CAR, A 2017 ACADIA, WILL NOT AUTO START, ALARMS GO OFF RANDOMLY, THEFT WARNING COMES ON AND HOOD OPEN WARNING COMES ON EVERY TIME CAR IS STARTED.. OUR DETERMINATION IS THE HOOD LATCH FROM OTHER FORUMS WHICH IS WHAT THE GARAGE ALSO DETERMINED. WE WERE TOLD ONLY TRUCKS WERE BEING REPLACED NOT THE CARS. WE DON'T FEEL THAT THIS IS SOMETHING WE SHOULD BE PAYING FOR SINCE IT IS OUT THERE THAT MANY HAVE THE PROBLEM. THE LATCH CAUSES THE THEFT PROBLEM WHICH EVENTUALLY CAUSES THE CAR NOT TO ADVANCE IN SPEED (CONNECTING TO THEFT) AND COULD CAUSE DEATH ON A MAJOR HIGHWAY WHEN ALL CARS ARE GOING 60 PLUS AND YOUR CAR WON'T MOVE. SOME PEOPLE WERE UNABLE TO START THEIR CARS. THIS IS MAJOR AND SHOULD BE CORRECTED WITH A RECALL. THIS MIGHT NOT SEEM MAJOR BUT IT CAN BE. WE BECAME LEERY IN DRIVING THE VEHICLE. I HAVE A TEEN DRIVER AND THE HOOD OPEN WARNING COMES ON MANY TIMES THROUGHOUT A DRIVE. YOU CAN CLEAR IT AND IT REAPPEARS WHETHER MOVING OR NOT. THIS HAS BEEN GOING ON WITH US FOR A GOOD MONTH. AGAIN, THIS HAPPENS WHILE STATIONARY AND MOVING. IT CAN COME ON AT ANY SPEED WHICH IS THE SCARY PART. WE HAVE LIMITED OUR DRIVE AND DRIVE AT A CONTROLLABLE SPEED BUT THAT DOESN'T MAKE IT SAFER. ONCE WE WERE STATIONARY WHEN THE ALARMS WENT OFF AND COULD NOT CLEAR. ALL THE WARNINGS CAME ON. COULDN'T UNLOCK CAR DOORS WITH REMOTE. WE SHOULD NOT HAVE TO PAY FOR THIS FIX! NO RECALL SHOULD HAVE TO HAVE A DEATH OR INJURY TO BECOME IMPORTANT!
