ON 9/4/15 I WAS BACKING A BOAT INTO THE LAKE USING THIS VEHICLE. I PUT THE VEHICLE INTO PARK, OR THOUGHT I DID, AND OPENED THE DRIVER DOOR. AS I EXITED THE VEHICLE ROLLED BACKWARDS, KNOCKED ME DOWN, AND THE ENTIRE VEHICLE, WITH BOAT AND TRAILER, WENT INTO THE LAKE. I HAVE NOTICED SINCE THEN THAT THE SHIFTER REQUIRES YOU TO HOLD IT IN PARK FOR A SECOND BEFORE THE PARK GEAR WILL ENGAGE. SLAMMING THE SHIFTER TOWARDS PARK, EVEN WITH THE BUTTON DEPRESSED AND FOOT ON THE BRAKE, WILL NOT ALWAYS ENGAGE THE PARKING GEAR. YOU MUST WAIT UNTIL THE PARKING GEAR LIGHT ON THE DASH IS ILLUMINATED. THIS IS NOT USER FRIENDLY. I WOULD SUGGEST A SENSOR BEING INSTALLED ON THE TRANSMISSION THAT AUTOMATICALLY SHIFTS INTO PARK WHEN THE DRIVER DOOR IS OPENED, MUCH LIKE THE MERCEDES GL450.
