TL* THE CONTACT OWNS A 2012 FORD F-450. WHILE DRIVING 40 MPH, THE VEHICLE BEGAN TO STALL AND THE CHECK ENGINE AND OIL PRESSURE WARNING INDICATORS ILLUMINATED. THE CONTACT WAS ABLE TO PARK THE VEHICLE ON THE SIDE OF THE ROAD AS IT STALLED AND TURNED OFF. THE VEHICLE WAS TOWED TO AN INDEPENDENT MECHANIC AND THEN TO BAYSHORE FORD TRUCK SALES (LOCATED AT 4003 N DUPONT HWY, NEW CASTLE, DE 19720, (302) 656-3160) WHERE IT WAS DIAGNOSED THAT THE ENGINE NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED. THE FAILURE MILEAGE WAS 38,500.
WHILE TRANSPORTING A PATIENT TO THE HOSPITAL THE ENGINE ON OUR 2012 FORD AMBULANCE SUDDENLY AND WITHOUT WARNING DERATED. THIS CAUSED OUR AMBULANCE TO SLOW DRAMATICALLY AND DELAYED TRANSPORT TO THE HOSPITAL. WE BROUGHT THE AMBULANCE TO THE DEALER WHO STATED THE ENTIRE DEF SYSTEM WOULD NEED TO BE REPLACED AT A COST OF $5,000! I RESEARCHING THE INTERNET THIS IS NOT AN UNCOMMON PROBLEM. I CONTACTED THE REGIONAL MANAGER FOR FORD AND HAVE HAD NO RESPONSE.
THIS VEHICLE IS AN AMBULANCE AND WAS DISPATCHED ON AN EMERGENCY CALL. THE CREW ATTEMPTED TO CRANK THE VEHICLE, BUT THE STARTER WOULD NOT EVEN ENGAGE. ANOTHER AMBULANCE HAD TO BE DISPATCHED TO THE CALL. IT WAS LATER DETERMINED THAT ONE OF THE FOUR EGT EXHAUST GAS TEMPERATUR SENSORS HAD FAILED AND DISABLED THE VEHICLE. HAD THE VEHICLE BEEN TRAVELING ON THE HIGHWAY, A VERY DANGEROUS SITUATION COULD HAVE OCCURRED. THERE WAS NOT AN OVER HEATED EXHAUST CONDITION NOR AN EXHAUST EMISSION PROBLEM AT THE TIME, WHICH IS WHAT THESE SENSORS ARE DESIGNED TO DETECT. THE POWERTRAIN CONTROL MODULE(PCM) SHOULD NOT BE PROGRAMED TO SHUT DOWN A VEHICLE BECAUSE OF ONE SENSOR. REDUCTION OF POWER MAY BE ACCEPTABLE. IF MORE THAN ONE SENSOR DETECTS A PROBLEM THEN THAT MAY BE ACCEPTABLE. OUR AGENCY HAS SEVERAL OF THESE VEHICLES AND HAS EXPERIENCED THE SAME ISSUE WITH MOST OF THEM.
THIS VEHICLE, WHICH IS AN AMBULANCE, WAS DISPATCHED TO AN EMERGENCY CALL. AS THEY TURNED INTO THE DRIVE OF THE FACILITY THE CHIMES SOUNDED AND THE ENGINE SHUT OFF. HAD THIS VEHICLE BEEN ON THE HIGHWAY AT THE TIME, IT WOULD HAVE BEEN A VERY DANGEROUS SITUATION FOR THE CREW INVOLVED. AT THE VERY LEAST, ANOTHER AMBULANCE HAD TO BE DISPATCHED TO THE CALL AND DELAYED CARE TO THE PATIENT. IT WAS DETERMINED LATER THAT THE EGT SENSOR HAD FAILED, ALTHOUGH THERE WAS APPARENTLY NO PROBLEM IN THE EXHAUST SYSTEM AT THE TIME.
