TRUCK HAS 3 PROBLEMS THAT CAN PUT MY FAMILY'S LIFE IN DANGER. 1- SOMETIMES OUT OF NOWHERE AT LOW SPEEDS WHEN YOU TURN THE STEERING WHEEL TO MAKE A LEFT OR RIGHT TURN THE 'STABILITRAC' LIGHT FLASHES IN THE SCREEN AND LOCKS AND WON'T LET YOU TURN THE STEERING WHEEL.AT THIS POINT YOU HAVE NO CONTROL OF THE STEERING WHEEL, IT LOCKS AND BOUNCES BACK AT YOU AND IF YOU KEEP TRYING TO TURN IT, THE ENGINE CUTS OFF ALL POWER AND IT STALLS, JUST DIES. I ALMOST GOT READ ENDED A COUPLE OF TIMES ALREADY DUE TO THIS PROBLEM. JUST THIS MORNING I WAS MAKING A RIGHT ONTO A LOCAL MCDONALD'S AND THE STEERING WHEEL LOCKED AND THE ENGINE DIED ON ME. I HAD TO QUICKLY TURN IT ON AGAIN AND KEEP GOING.ANOTHER TIME IT HAPPEN AS I WAS MERGING INTO TRAFFIC. VERY SCARY! PROBLEM NUMBER TWO, I THINK ITS JUST A MATTER OF TIME BEFORE THE STEERING WHEEL LOCKS ON ME ON HIGH SPEEDS. SOMETIMES WHEN I'M ON THE FREEWAY, THE SAME CHIMES COME ON WHEN I STEP ON THE BRAKES, THE CENTER SCREENS GOES BLACK, AND THE SAME 'STABILITRAC' WARNING COMES ON THE SMALLER SCREEN BEHIND THE STEERING WHEEL. I'M AFRAID TO TAKE IT ON A WINDING ROAD FOR FEAR THAT THE STEERING WHEEL WILL LOCK ON ME CAUSE AN ACCIDENT. 3- SERVICE BRAKE CONTROLLER SIGN AND CHIMES COME ON ANT WON'T GO AWAY. IT JUS KEEPS ON POPPING ON AND ON AND ON AND THEY GO AWAY WHEN YOU TURN OFF THE TRUCK, AND COME ON AGAIN MONTHS OR WEEKS LATER. I DID HAVE IT CHECKED AT MY LOCAL DEALERSHIP.THEY TESTED IT, SOLD ME NEW GROUND AND HOT WIRES. IT WAS GOOD FOR ABOUT 4 WEEKS BEFORE THE SAME PROBLEMS CAME BACK AGAIN. I DID SOME RESEARCH ON SOME OF THE FORUMS AND YOU TUBE VIDEOS AND BY FAR I'M THE ONLY ONE WITH THE SAME PROBLEM. VERY AFRAID TO CAUSE AN ACCIDENT.
