2004 Cadillac Escalade Ext

1ST INCIDENT 1) I WAS GOING TO PARK IN A SPOT BETWEEN TWO BUILDING, ONLY LARGE ENOUGH FOR ONE VEHICLE. I CAME DOWN THE ROAD, WHICH HAS A DECLINE TO IT, AND TURNED RIGHT, INTO THE PARKING SPOT. DUE TO THE ROAD BEING 1 WAY, AND THE PARKING SPOT BEING TIGHT, IT IS IMPOSSIBLE TO TURN THE VEHICLE DIRECTLY INTO THE PARKING SPOT. I TURNED THE VEHICLE AND HAD TO BACK UP TO GO STRAIGHT INTO THE PARKING SPOT. I PRESSED THE BRAKE, SHIFTED INTO REVERSE, AND PRESSED THE GAS PEDAL. MEANWHILE, A LADY WALKED IN FRONT OF MY VEHICLE ON THE SIDEWALK. 2) THE VEHICLE ROLLED FORWARD, EVEN THOUGH THE RPMS WERE AT APPROXIMATELY 2200 RPMS AND THE VEHICLE WAS IN REVERSE. I HIT THE BRAKE, BUT THE VEHICLE HAD ALREADY HIT THE LADY. SHE WAS FORTUNATELY FINE, AND CONTINUED ON HER WAY. 3) I TOOK THE VEHICLE TO THE DEALERSHIP, WHERE THEY TOLD ME IT WAS WORKING WITHIN IN DESIGN PARAMETERS. THEY SAID THERE WAS NOTHING MORE THAT COULD BE DONE. I CALLED CADILLAC CUSTOMER CARE, AND INFORMED THEM OF THE PROBLEM. THEY ALSO SAID AT THE TIME THERE WAS NOTHING THEY COULD DO, AND CHALKED IT UP TO A FLUKE. 2ND INCIDENT 1) I PARKED IN A PARKING LOT AGAIN WITH A DECLINE. ABOUT 2 FEET IN FRONT OF THE VEHICLE WAS A CEMENT POST. I CAME OUT, STARTED THE TRUCK, PRESSED THE BRAKE, AND SHIFTED INTO REVERSE. 2). I PRESSED THE GAS, THE RPMS WERE OVER 2000 RPMS, AND THE VEHICLE ONCE AGAIN DID NOT REVERSE BUT RATHER ROLLED FORWARD INTO THE CEMENT POST, CRACKING MY FRONT BUMPER. AFTER THAT, THE REVERSE ENGAGED AND THE TRUCK STARTED REVERSING. 3). THE DEALERSHIP CURRENTLY HAS THE VEHICLE, AND IS TELLING ME TO COME PICK IT UP, EVEN THOUGH THEY HAVE DONE NOTHING TO FIX THIS PROBLEM. I ASKED WHAT IT WAS GOING TO TAKE BEFORE THEY DID SOMETHING, AND THEY SAID THERE IS NOTHING THEY CAN DO. I HAVE CALLED CADILLAC CUSTOMER CARE AGAIN, LEFT 3 MESSAGES, AND STILL AHVE NOT HEARD BACK. I AM CONCERNED ABOUT THE LIABILITY OF DRIVING THIS VEHICLE AT THIS POINT.
