NHTSA Complaint #10717655 — 2011 BUICK ENCLAVE

I AM NOT SURE WHERE TRANSMISSION FALLS IN THE ABOVE LIST. EVER SINCE I PURCHASED THE VEHICLE IT ROLLS BACKWARDS WHEN STOPPED ON A HILL. I HAVE TO USE BOTH FEET TO KEEP IT FROM ROLLING BACK AND HITTING THE CAR BEHIND ME. I WAS TRYING TO BACK UP IN A PARKING SPACE THAT WAS UP HILL AND IT ROLLS FORWARD ALSO. I ASKED THE DEALERSHIP NOT LONG AFTER I DISCOVERED THIS ISSUE AND THEIR RESPONSE WAS OH IT IS SUPPOSED TO DO THAT. I FIND THAT HARD TO BELIEVE, IT IS DANGEROUS. IT'S NOT LIKE THIS IS A 5 SPEED WITH A CLUTCH BUT THAT IS HOW YOU HAVE TO TREAT IT ON HILLS.
