Shift to park not happening. Stop the car and then the shift to part indicator shows up in the driver information center. So far I have been able to clear it out. Going into the dealer first thing in the morning. I have looked and there appears to be a class action on this issue and a TSB. I just bought this vehicle and was not told about this issue.

WHEN I PUT MY CAR IN PARK AND TURN OFF IT WILL RANDOMLY SAY "SHIFT TO PARK" IT STARTED DOING THIS IN AUG OR SEPT 2019 THE CAR WAS UNDER WARRANTY AND I BROUGHT IT TO A DEALER TO "FIX". FAST FORWARD APRIL 2021 IT STARTED TO SAY SHIFT TO PARK AGAIN AND CAR IS NO LONGER UNDER WARRANTY. CALLED DIFFERENT DEALERS EVEN THE ONE I BROUGHT THE CAR TO FIX PROBLEM (THAT WAS A JOKE), THEY KNOW ITS A PROBLEM AND SAYING SINCE THAT PART GOT FIXED IN 2019 WITH A BAD PART AND NOW THERE IS A A NEWER FIX THAT SHOULD WORK BETTER, BUT I WILL HAVE TO PAY FOR DIAGNOSTIC TEST AND PART AGAIN. AGAIN THEY KNOW IT IS A PROBLEM WITH THESE CARS AND IT NEEDS TO BE RECALLED. I HAVE TO TURN THE CAR OFF AND ON RESHIFT, PUSH THE SHIFTER HARDER, ETC TO GET THE MESSAGE TO GO AWAY SO I CAN TURN MY CAR OFF.
