ON TWO OCCASIONS AFTER PUTTING THE VEHICLE IN PARK, TURNING OFF THE IGNITION, REMOVING THE KEY AND EXITING THE VEHICLE, IT ROLLED BACK AND ONLY STOPPED WHEN DRIVER JUMPED BACK IN AND APPLIED THE BRAKE. THIS OCCURRED ON A FLAT GARAGE SURFACE (NO INCLINE) ON BOTH OCCASIONS, WITH DIFFERENT DRIVERS ON EACH OCCASION. GMC DEALER SAYS THEY CAN NOT REPLICATE THE ISSUE AND THERE IS NOTHING TO REPAIR. THIS VEHICLE IS DANGEROUS, AS IT CAN ROLL BACK UNEXPECTEDLY, POTENTIALLY CAUSING SERIOUS BODILY INJURY OR DEATH, OR DAMAGE TO PHYSICAL PROPERTY. GMC RECALLED THE 2009 ACADIA FOR THE SAME ISSUE PREVIOUSLY, BUT MAINTAINS THERE ARE NO ISSUES WITH MY VEHICLE. I FOUND ADDITIONAL COMPLAINTS FOR THIS ISSUE ON THE 2008 ACADIA ON THE INTERNET AS WELL, SO THIS ISSUE IS NOT UNIQUE TO ME. *TR
