2017 Ford Transit Electrical System

Trailer lights do not work issues with the wires short out the fuses can not get it fixed.

THE RIGHT TAIL LIGHT SEAL ISN'T WORKING, ALLOWING MOISTER IN THE LIGHT. THIS IS CORRUPTING THE WHOLE SYSTEM. THE RADIO, AC, RUNNING BOARDS, FIELD MONITORING SENSORS, AIRBAG SYSTEM, ALL TURN OFF AND ON WHILE DRIVING. MY VEHICLE ONLY HAS 38,000 MILES ON IT. THERE A MULTIPLE COMPLAINTS ON YOUTUBE AND OTHER FORD WEBSITES ABOUT THIS ISSUE.THE HOUSING FOR THE TAILLIGHT IS TERRIBLE AND NOT SEALED FOR THE LONG HAUL. THE DEALERSHIP HAS EVEN HAD TO DEAL WITH THIS MULTIPLE TIMES. THEY TOLD ME THERE IS NO CRACKS OR CHIPS THAT WOULD BE CAUSING THIS, JUST IMPROPER SEALING FROM THE FACTORY. IT IS SCARY TO THINK THAT THE AIRBAG SYSTEM FAILS FROM THIS FAULTY TAIL LIGHT.

THERE WERE 9 OF US IN OUR 2017 FORD TRANSIT, DRIVING ON ROUTE 15 81 MILES SOUTH OF LAS VEGAS, NV, WITH THE CRUISE CONTROL ON AT 75 MPH WHEN THE VAN SHUT OFF WHILE IN MOTION. PULLED TO THE SIDE OF THE ROAD. WAITED 2.5 TO 3 HOURS FOR A FLATBED TOW TRUCK WHILE TEMPERATURE WAS 108 TO 109 DEGREES F. VEHICLE TOWED TO FRIENDLY FORD, LAS VEGAS, NV. MILEAGE ON VEHICLE WAS 13,744 MILES. DEALER FOUND FUSE F16 BURNED OPEN AND CODES P025A AND U0109. THEY REPLACED THE FUSE F16 AND ROAD TESTED FOR 15 MILES AND RETURNED THE VAN TO US. THEY CONTACTED FORD TECHNICAL HELP. THAT FUSE POWERS THE FUEL PUMP RELAY AND FUEL PUMP CONTROL MODULE AND PCM. SEEMS LIKE THIS SAME SCENARIO CAN AND WILL HAPPEN AGAIN UNDER THE SAME CONDITIONS. FAILURE MODE WAS WHEN WE WERE DRIVING UPHILL SLIGHTLY AT 1 OR 2 PERCENT UPHILL GRADE WITH 3/8 OF FUEL IN THE TANK. SINCE THEN WE DROVE 400 MILES WITHOUT A PROBLEM. AFRAID TO DRIVE IN THE LEFT CARPOOL LANE BECAUSE IT IS DANGEROUS TO STALL OUT (COULD GET KILLED BY A TRUCK OR BUS)

THE DASH DISPLAY WOULD GO COMPLETELY BLANK INTERMITTENTLY, BEGINNING WITH A CHIME AND "LOW BRAKE FLUID" WARNING. ALL GAUGES WOULD GO TO ZERO AND THERE WAS NO INFORMATION DISPLAYED AFTER A COUPLE OF SECONDS. THIS WOULD OCCUR WHILE TURNING OR ACCELERATING. WE TOOK IT TO A FORD DEALER WHO FOUND MULTIPLE COMMUNICATION FAULTS AND RECOMMENDED REPLACING THE INSTRUMENT CLUSTER. THIS WAS DONE WITH NO CHANGE. I FINALLY TRACED THIS DOWN TO AN UNSECURED WIRING HARNESS THAT GOES UP INSIDE THE RIGHT REAR PILLAR OF THE VEHICLE, WHICH WAS SWINGING AROUND AND SHORTING OUT THE MEDIUM SPEED CAN BUS. I SECURED THE WIRING HARNESS TOWARDS THE INSIDE OF THE VEHICLE WITH A CABLE TIE AND THE PROBLEM HAS NOT RETURNED. BUT IT WAS VERY DISTRACTING WHILE IT HAPPENED. WE HAVE NOT HAD ANY SIMILAR PROBLEM WITH ANY OF OUR OTHER BIG TRANSITS.

TL* THE CONTACT OWNS A 2017 FORD TRANSIT. WHILE THE VEHICLE WAS PARKED, THE CONTACT NOTICED A BURNING ODOR COMING FROM THE FRONT OF THE VEHICLE. THE CONTACT NOTICED THAT THE STEREO SPEAKER ABOVE THE FRONT DRIVER'S SEAT STARTED TO SMOKE, AND FLAMES APPEARED FROM TWO WIRES THAT RAN FROM THE SUBWOOFER. THE CONTACT EXTINGUISHED THE FIRE BY UNPLUGGING ALL THE WIRING FROM A WALL COMPARTMENT. THE CONTACT SUSTAINED BURNS TO THE FINGERS, WHICH DID NOT REQUIRE MEDICAL ATTENTION. IN ADDITION, WHEN USING THE GENERATOR, THE POWER FAILED. THE RV WAS TAKEN TO AN INDEPENDENT MECHANIC WHERE IT WAS DIAGNOSED THAT THE POWER CORD NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED. IT WAS UNKNOWN IF A DEALER WAS CONTACTED OR NOT. THE MANUFACTURER STATED THAT THEY WOULD REPLACE THE GENERATOR. THE APPROXIMATE FAILURE MILEAGE WAS 6,000.
