I WAS PARKED ON A SLOPED DRIVEWAY (ABOUT 10 - 15 DEGREES). I STARTED THE ENGINE, STEPPED ON THE BRAKE PEDAL AND TOOK THE CAR OUT OF PARK INTO DRIVE. BRAKE PEDAL WAS NORMAL. I STARTED TO ROLL FORWARD AND WHEN I PUSHED THE BRAKE PEDAL THE CAR DID NOT SLOW. I SLAMMED THE BRAKE PEDAL AND IT WENT ALL THE WAY TO THE FLOOR. AT THIS POINT I WENT OFF THE END OF THE DRIVEWAY ONTO A 45 DEGREE DOWNWARD SLOPED LAWN; THEN INTO A WOODED AREA AT THE TOP OF A RAVINE. I SLAMMED INTO A TREE.

THE TRUCK ONLY HAS 83,502 MILES ON IT AND I'VE BEEN INFORMED THAT THE NEXT TIME I TAKE IT FOR AN EMISSIONS TEST (A REQUIREMENT IN NEW MEXICO) IT WILL FAIL. I FINALLY SAVED UP ENOUGH MONEY TO GO AN OUTSIDE REPAIR SHOP ON JULY 15, 2014 TO GET MY FUEL INJECTORS REPLACED AND THE TOTAL CAME TO $4763.78. I FOUND OUT THAT THERE WERE TWO STRIPPED BOLTS INDICATING THAT THE FUEL INJECTORS...

MY VEHICLE BEGAN LOSING COOLANT. I TOOK THE VEHICLE TO A MECHANIC, WHO HAS TOLD ME THAT THE CYLINDER HEAD IS CRACKED AND LEAKING. THIS IS DUE TO FAULTY CASTING ON THE CYLINDER HEAD.THE COOLANT IS LEAKING INTO THE HEADS, AND CAUSING THE OIL TO LOSE IT'S ABILITY TO PROTECT THE ENGINE FROM WEAR. I HAVE SEEN THAT THERE ARE MANY PEOPLE WITH THIS ISSUE, AND IT IS A VERY COSTLY REPAIR. *TR
