2011 FORD F-350 SD Engine And Engine Coolingexhaust System Problems

FORD F350SD CREW CAB W/ 6.7 DIESEL MOTOR...VEHICLE WAS BEING DRIVEN WHEN SUDDENLY WARNING MESSAGE CAME ACROSS DASH THAT VEHICLE WAS "SHUTTING DOWN" AND TO PULLOVER VEHICLE IMMEDIATELY. WITHIN 10 SECONDS VEHICLE BEGAN DECELERATING AND CAME TO A COMPLETE SHUTDOWN. IT WAS VERY DIFFICULT TO MANEUVER VEHICLE AS POWER STEERING AND EVERYTHING STOPPED WORKING. WITH WIFE IN A PANIC, SHE BARELY GOT THE TRUCK OFF THE HIGHWAY, BEFORE COMPLETE SHUTDOWN OF VEHICLE! CALLED LOCAL FORD DEALER, WHICH DID HAVE THE TRUCK TOWED IN TO DEALERSHIP, UNDER FORD WARRANTY. TRUCK WAS DIAGNOSED AS HAVING A "FAULTY" EGT EXHAUST SENSOR, GAVE ESTIMATE TO FIX OF AROUND $600.00. CLAIMS IT WAS NOT PART OF THE POWERTRAIN, SO NO WARRANTY COVERAGE OF THE COSTS OF REPAIR! TOTALLY FRUSTRATED WITH FORD FOR THIS INCIDENT AND LACK OF SUPPORT OR CONCERN FOR THIS FAILURE, I APPEALED TO THEIR CUSTOMER SERVICE DEPT. AND BASICALLY GOT NOWHERE! NOW...
