2014 Lincoln Navigator Speed Control & Cruise Problems

DRIVING AT ABOUT 25-30 MPH ON SIDE STREET AND MY CAR SURGED OUT OF CONTROL.. I ATTEMPTED TO CONTROL THE SPEED WITH THE BRAKE. I WAS ABOUT 100-150 FEET FROM A BUSY INTERSECTION (40 HIGHWAY -THE CAR SURGING REALLY FAST. I NEEDED TO MAKE SOME QUICK DECISIONS TO PROTECT A LOT OF PEOPLE FROM BEING BADLY INJURED OR KILLED. I HAD TO LEAVE THE KEY ON SO THAT I COULD CONTROL THE CAR AWAY FROM 40 HIGHWAY- SO I TURNED INTO A LITTLE PATH TO MY RIGHT WHICH LED ME INTO BIG TREES OR A THICKET. I CHOSE THE THICKET NOT KNOWING THERE WAS A TERRAIN IN THE MIDDLE. ACTUALLY , THE CAR WAS GOING SO FAST - I HAD VERY LITTLE CONTROL AT THIS TIME. MY CAR ATTEMPTED TO GO UP ON ONE SIDE FLEW ABOUT 20 FEET THROUGH THE AIR WHEN IT LANDED A SMALL TREE KEPT IT FROM ROLLING OVER AND CAME OUT ON A HILL AGAIN HEADING FOR THE BUSY 40 HIGHWAY. AS LUCK WOULD HAVE IT ,THE HILL WAS WET AND MUDDY FROM RAIN AND I PULLED THE STEERING WHEEL AS HARD AS I COULD TO MY RIGHT TURNING THE CAR UP THE HILL - AWAY FROM THE TRAFFIC. THE SOFT GROUND HELPED TO PUT THE CAR IN A SKID AND FLIPPED THE BACK END AROUND. AS IT WAS HEADING UP THE HILL I QUICKLY TURNED OFF THE KEY AND GOT THE CAR STOPPED. WHEN THE TOWING COMPANY CAME TO PICK UP THE CAR -UNSAFE STILL SURGING. TOOK CAR TO BOB SIGHTS FORD . ( PREVIOUSLY,THEY REPAIRED THE POPPING NOICE DESCRIBED IN ANOTHER 'NATHSA' COMPLAINT. ) CAR WAS TOTALED. I TRIED TO GET THEM TO HOOK THE CAR UP TO THE MECHICANICAL MODULE SCANNER FOR THE SAFETY OF OTHERS. INSTEAD THEY PUT IT ON THE BODY SCANNER THEY USE TO LOCATE ALL COMPONENTS WHEN REPAIRING A WRECKED CAR (WHICH I PAID FOR) WOULD NOT PUT THE CAR ON THE MECHNICAL SCANNER EVEN THOUGH IT WAS STILL SURGING WHEN I FINALLY RELEASED IT TO THE INSURANCE COMPANY. MY BIGGEST CONCERN IS THE SAFETY OF OTHERS. I EVEN TALKED TO ONE OF THE OWNERS OF THE DEALERSHIP.
