When the vehicle is put in park and attempted to shutoff, is message appears on dash that says "shift to park". This problem was reported to the dealer the 1st time it happened on June 11. , 2018. The dealership replaced the shifter. On July 31, 2020 again the shift to park message appeared. The dealership again replaced the shifter, (that shorted out) and this time installed a wiring harness that had a resister installed in the harness to prevent damaged to the shifter assembly from the over current that goes to the shifter. The service advisor said they have had numerous vehicles with this problem and the com[any should do a recall. How long before it does it again and a another $631. 36 repair bill.
When shifting the vehicle to park and then shutting off the engine, I get an error message �action required- shift to park�. The vehicle is already in park! I've had to jiggle the shifter, press the brake while jiggling the shifter, restart the vehicle put in reverse, then back in park, and jiggle some more. The radio and lights (both interior & exterior) will not power off and the door chimes nonstop. This happens randomly and it has been a little over a month since the last incident which occurred two days after I had to replace the battery because I missed the error message heading in to work. The last 2 days my husband has disconnected the battery because nothing will work to power off radio & lights. I've had to replace the battery twice now in a new vehicle leased in 2016. The first time was due to brake recall, my vehicle being the only 2017 GMC Acadia denali effected by that recall. The brake lights would remain on because the brake was basically sticking, draining the battery. That issue also disabled the cruise control as that feature is unavailable when breaking! this vehicle also had repair to wiring in driver side door due to water getting into the door frame from outside and corroding wires causing detection issues with the key fob. I could not unlock my doors without removing the key to manually unlock. While in the car wash, the vehicle lost connection with my key and the driver's seat moved all the way back as it would for easy exit which I had disabled. Message stating key not detected wouldi was told a needed a new battery in my fob, dealership replaced, called & said everything was working as it should. They ran the vehicle through the car wash before I arrived to pick up the car. When I tried to unlock the doors, the vehicle would not recognize the fob. Thank goodness the service rep was there to witness the malfunction.
