2018 GMC Acadia UNKNOWN OR OTHER

CAR WILL NOT RECOGNIZE I'VE SHIFTED TO PARK WHEN I TURN OFF THE VEHICLE. IT SAYS SHIFT TO PARK WHEN I ALREADY HAVE, AND I HAVE TO START THE CAR AND SHIFT AGAIN OVER AND OVER TO PARK FOR IT TO WORK. VERY CONCERNED ABOUT SAFETY.

'SHIFT TO PARK' ERROR MESSAGE IS SHOWING WHEN MY VEHICLE IS ALREADY IN PARK AND I'M TRYING TO TURN THE VEHICLE OFF. I PURCHASED THIS VEHICLE LESS THAN A MONTH AGO AND IT CURRENTLY HAS 33K MILES ON IT. I'VE HAD TO TURN THE VEHICLE BACK ON SEVERAL TIMES TO GET THIS ERROR TO GO AWAY. WHEN THE MESSAGE FLASHES I'VE EVEN EXPERIENCED THE VEHICLE ROLLING INDICATING IT IS IN FACT NOT IN PARK ALTHOUGH THE SHIFTER IS IN PARK POSITION. THIS NEEDS TO BE RECALLED IMMEDIATELY AND I WILL ALSO BE CONSULTING AN ATTORNEY AS THIS IS A KNOWN ISSUE WITH NO CLEAR FIX (MANY PEOPLE WHO HAVE HAD THE SHIFTER REPLACED ARE HAVING THE SAME PROBLEMS AGAIN) AND THE PART THAT NEEDS TO BE REPLACED IS ON BACKORDER. PEOPLE'S VEHICLES LITERALLY CANNOT TURN OFF RESULTING IN BATTERIES DYING AMONG THE VERY OBVIOUS SAFETY CONCERNS. HOW IS THIS LEGAL?

EXPLODED SUNROOF - THE SUNROOF EXPLODED WHEN I WAS NOT IN THE CAR. I HEARD THE GLASS FALLING IN TO THE SUN SHADE WHEN I CLOSED THE DOOR. TOOK ME SEVERAL DAYS TO RECOGNIZE AND FIGURE OUT WHAT THE SOUND WAS. NO ROCKS, NO SIGN OF ANYTHING FALLING ON THE ROOF TO DAMAGE. THE GLASS APPEARED TO BE PUSHED OUT AS CAN BE SEEN ON THE PHOTOS.

WHEN PUSHING VEHICLE IGNITION BUTTON "START/STOP" TO TURN VEHICLE "OFF" IT WILL TURN THE ENGINE OFF BUT KEEP THE VEHICLE STILL "ON" USING THE BATTERY. IF I OPEN THE DOOR AND SHUT IT, THE HORN HONKS TO ALERT THAT THE VEHICLE IS STILL "ON" AND NOT COMPLETELY STOPPED. THE ONLY WAY TO GET THE IGNITION BUTTON TO ACKNOWLEDGE THE VEHICLE IS OFF IS BY JERKING THE GEAR SHIFT UNTIL THE GREEN LIGHT GOES TO "OFF". IT DOES NOT DO IT EVERY TIME I TURN THE VEHICLE OFF, BUT IT DOES IT ABOUT EVERY OTHER TIME. I WILL TAKE IT TO THE DEALERSHIP VERY SOON FOR THEM TO LOOK AT THIS ALSO.

ONE DAY MY CAR STARTED TELLING ME SHIFT TO PARK WHILE IT WAS IN PARK. AS THE DAY PROGRESSED IT BECAME WORSE AND WORSE. RESULTING IN THE CAR NOT SHUTTING OFF. PUTTING IT INTO GEAR AND BACK TO PARK WAS NOT HELPING. THE LAST TIME IT TOOK NEARLY 30 MINUTES BEFORE I COULD GET THE CAR TO SHUT DOWN COMPLETELY AS IT KEPT STARING SHIFT TO PARK. CAR WAS NOT MOVING HAD ONLY GONE WITHIN CITY LIMITS WITH MAX SPEEDS OF 45MPH.
