Electrical system

18 reports7 fires
“I had been driving for about 15 minutes and then I noticed a burning plastic smell. It was dark so my headlights were on. I felt heat coming from under the dash by the pedals. I started to watch my dash to see if the truck was over heating or the check engine light would come on but neither of those happened. The next light I stopped at I could see smoke coming from the driver side air vents. I pulled over and opened the hood and nothing. Well after some extensive searching I located the issue. The headlight switch to control my headlights was completely melted. Had I not pulled over and popped the hood, Im sure the truck would have continued to catch fire. I replaced the fuses and switch and have not had any problems there but I do now have problems with my odometer lights. I cannot seem to keep that fuse from popping. Everyone I replace just pops again. So I have an electrical issue somewhere I guess I'll just have to start chasing wires!”

Suspension

“HELLO, LUCKILY I MADE IT HOME BEFORE THIS HAPPENED AS I WAS TOWING MY TRAILER WITH A COUCH AND CHAIR ON IT. I GOT HOME AND STOPPED IN FRONT OF MY HOUSE, THEN HAD TO MOVE THE TRUCK. WHEN I STEPPED ON THE GAS TO MOVE, THERE WAS A HORRENDOUS BANG, A CLUNKING NOISE AND THE REAR OF THE VEHICLE DROPPED DOWN ALMOST TO THE GROUND. UPON JACKING THE VEHICLE UP AND EXAMINING THE DAMAGE, THE REAR LOWER CONTROL ARMS ROTTED ON BOTH SIDE AND COLLAPSED LIKE PRETZELS, ALLOWING THE REAR DIFFERENTIAL TO TWIST, SNAPPING THE DRIVESHAFT FLANGE WHERE THE UNIVERSAL GOES AND BLOWING OUT BOTH REAR SUSPENSION AIR SPRINGS. AS I SAID, LUCKILY IT WAITED UNTIL I WAS HOME FOR THIS TO HAPPEN. IF IT HAD HAPPEN ON ROUTE 287 ON MY WAY HOME AT 65MPH, I'M SURE THE RESULTS WOULD HAVE BEEN CATASTROPHIC. I CAN'T IMAGINE THAT I WOULD HAVE BEEN ABLE TO CONTROL THE VEHICLE. EXAMINING THE UPPER CONTROL ARMS SHOWED THEY ARE ROTTED TO! I CONTACTED THE FORD DEALER I HAVE USED FOR REPAIRS AND FORD CUSTOMER SERVICE. THE DEALERSHIP SAID THEY HAVE SEEN IT BEFORE, BUT TO THEIR KNOWLEDGE, FORD IS NOT ASSISTING FOR THIS PROBLEM. WHEN I CONTACTED FORD CUSTOMER SERVICE, THEY TOOK MY VIN NUMBER AND SAID THERE WERE NO…”

“I OWN A 2001 LINCOLN NAVIGATOR WITH A 5.4L ENGINE. I WAS ON MY WAY TO WORK AND WAS GOING APPROX. 15 MPH WHEN I HEARD A BANG COMING FROM THE FRONT OF THE CAR. AT FIRST I THOUGHT I HAD HIT SOMETHING OR SOMETHING WAS FALLING OFF THE CAR. I PULLED OVER TO THE SIDE OF THE ROAD AND AT THIS TIME THE ENGINE STARTED TO RUN ROUGH. I SHUT IT OFF AND CHECKED UNDER THE HOOD BUT COULD NOT SEE ANYTHING WRONG. I THOUGHT, AFTER RESTARTING THE ENGINE THAT IT MIGHT BE A BAD SPARK PLUG. AS I STARTED OFF THE CAR WAS STILL RUNNING BAD SO I DECIDED TO RETURN HOME.THE NEXT DAY, 10/09/2010, I DECIDED TO CHECK FURTHER AND REMOVED THE THREE OF THE SPARK PLUGS ON THE DRIVERS SIDE, BUT THE LAST ONE WHICH IS AT THE FRONT OF THE ENGINE I NOTICED THE COIL WAS ALL TORN APART AND THE END OF THE COILED WIRE WAS STICKING OUT FROM THE PLUG HOLE. I PULLED SAID WIRE OUT AND SAW THE SPARK PLUG AT THE BOTTOM OF THE HOLE. IT APPEARED TO HAVE BEEN BLOWN OUT OF ITS THREADS. ALSO TO BE NOTED IS THE SMELL OF GAS WAS VERY APPARENT AND BECAUSE THE SPARK PLUG WAS DAMAGED, THE GROUND WAS FORCED AGAINST THE ELECTRODE AND WAS UNABLE TO SPARK. IF IT DID, I'M SURE THE ENGINE WOULD HAVE CAUGHT ON FIRE. I ALSO FOUND…”
