HIGH PRESSURE FUEL LEAK CAUSING FUEL AT A HIGH PRESSURE TO BE SPRAYED ALL OVER ENGINE COMPARTMENT, EXHAUST SYSTEM, BRAKES AND COAT THE UNDERCARRIAGE WITH FUEL. WHILE DRIVING AT HIGHWAY SPEED (70 MPH) A MIST OF VAPOR APPEARED BEHIND THE TRUCK CAUSING OTHER VECHICLES TO PULL TO THE SIDE TO AVOID THE FUEL BEING SPRAYED. CHECK ENGINE LIGHT ILLUMINATED. STOPPED THE VEHICLE AND MASSIVE FUEL SPILL COVERED THE CONCRETE AND DRIPPED FROM EVERY UNDERCARRIAGE LOWPOINT. SMOKE AND SIZZLING WAS OBSERVED AND WE FLED A SAFE DISTANCE FROM VEHICLE. THIS IS A REPEAT FAILURE OF THE HIGH PRESSURE FUEL LINE. THIS IS THE FIFTH FAILURE AND IT HAS SEVERAL MORE ATTEMPTED TO SOLVE THE LEAK PRIOR TO CLOSING THE WORK ORDERS. FAILURE APPEARS TO HAPPEN AFTER APPROXIMATELY 10,000 MILES OF BEING IN SERVICE. NO ROOT CAUSE HAS BEEN ESTABLISHED FOR THIS FAILURE. VEHICLE IS IN THE POSSESSION OF FCA AND NO CLEAR PATH HAS BEEN GIVEN TO ME ON HOW THIS IS GOING TO BE RESOLVED AND I AM WITHOUT MY TRUCK. NO PATH HAS BEEN GIVEN TO REPAIR COMPONENTS THAT HAVE BEEN SEVERELY CONTAMINATED BY DIESEL (BRAKE PADS, ROTORS, VERSUS RUBBER COMPONENTS, ETC) THE ATTACHED PHOTO SHOWS THE AMOUNT OF FUEL THAT POURED OUT IN THE DEALER SERVICE BAY. ADDITIONAL PHOTOS AVALABLE ON REQUEST. THE DATE IS FOR THE LATEST FAILURE. TODAY I AM AT 25 DAYS WITH NO CLEAR PATH TO CLOSE THIS CONCERN.
