2014 FREIGHTLINER XC-R Steering Problems

FOR THREE YEARS SINCE THE FIRST DAY I GOT IT THE ENGINE WILL COMPLETELY SHUT OFF. NO POWER STEERING NO GAUGES NO THROTTLE CONTROL ALL WHILE GOING DOWN THE ROAD AT 55 - 65 MPH. BY THE TIME I DEAD STICK IT TO THE SIDE OF THE ROAD THE ENGINE AUTOMATICALLY STARTS AND ALL APPEARS OK. I FEAR FOR MY LIFE AND MY FAMILY IF I AM ON A MOUNTAIN ROAD AND IN A TURN WHEN THIS MIGHT HAPPEN. IT MAY GO WEEKS BEFORE IT DOES IT AGAIN OR A DAY BUT IT USUALLY IS 1 TO XX HOURS ON THE ROAD TRAVELING ON HIGHWAY OR FREEWAYS. I HAVE HAD FREIGHTLINER SERVICE CENTER AT THE FACTORY LOOK AT IT SEVERAL TIMES AND ALSO CUMINS PLACES. LATELY I HAVE HAD SEVERAL RV REPAIR PLACES TOO BUT PROBLEM DOES NOT HAPPEN SITTING IN THE SHOP IDLING OR A SHORT DRIVE AROUND THE...

SINCE I PURCHASED THIS VEHICLE 10/28/2013 THE ALIGNMENT HAS BEEN OFF. IT WAS FIRST NOTICED AS DOG TRACKING THEN TIRE WEAR ON THE BACK AND THEN TIRE WEAR ON THE FRONT. NOW AFTER HAVING IT ALIGNED 3-4 TIMES I HAVE BADLY WORN OUT TIRES THAT ARE A DANGER AND IN NEED OF REPLACEMENT. THE LAST ALIGNMENT WAS AT THE FREIGHTLINER FACTORY SERVICE CENTER IN GAFFNEY, SOUTH CAROLINA AND CURRENTLY THE ALIGNMENT SHOP IS CLAIMING THEY DID THE CASTER BACKWARDS AND TOE IN WAS WAY OFF. ALSO THE BELL CRANK WAS READY TO FALL OFF. TIRES ARE 200,000 MILE TIRES AND ARE WORN OUT AFTER 40,000 MILES.
