1999 FORD E350 CAUGHT FIRE AND BURNED TO A TOTAL LOSS WHILE SITTING COLD IN MY DRIVEWAY. I BOUGHT THE VEHICLE USED ON NOV 8, 2010. DEC 12, 2010 I DROVE ABOUT 3 MILES TO THE GROCERY AROUND 20:30; I RETURNED HOME AND PARKED THE VEHICLE IN MY DRIVEWAY ABOUT 20:45. ABOUT 22:15 A PASSING CAR OBSERVED FLAMES COMING FROM THE FRONT OF THE VEHICLE AND FLARING TO CONTACT MY HOUSE. THE WITNESS ALERTED ME AT MY DOOR. I IMMEDIATELY GRABBED THE GARDEN HOSE AND ATTEMPTED TO SPRAY WATER INTO THE FRONT GRILL, LEFT SIDE TO PUT OUT THE FIRE. I COULD NOT SEE WHERE THE ACTUAL FIRE WAS AS THE HOOD WAS CLOSED, I SPRAYED WHERE THE FLAMES EXITED THE GRILL. THE WIND WAS BLOWING ABOUT 20 MPH AND I COULD NOT EXTINGUISH THE FLAMES. THE VEHICLE WAS FACING NORTH, THE WIND BLOWING FROM WEST TO EAST. THE FLAMES BEGAN TO SHOOT OUT FROM THE PASSENGER WHEEL WELL IN A HORIZONTAL STREAK AS THE WIND STOKED THE FIRE. NEIGHBORS CALLED 911 WHILE I DIVERTED THE WATER SPRAY FROM THE VEHICLE TO THE HOUSE AND GARAGE SINCE THE VAN WAS PARKED WITHIN 2 FEET OF THE GARAGE DOOR AND THE WIND NOW HAD FLAMES SHOOTING 8-12' HIGH AND BRUSHING THE WOOD GARAGE DOOR. THE FIREMEN ARRIVED, KNOCKED THE VEHICLE HOOD OFF WITH A TOOL AND SPRAYED THE ENGINE COMPARTMENT TO EXTINGUISH THE FIRE. DUE TO THE WIND, THE VAN WAS COMPLETELY FIRE GUTTED AND A TOTAL LOSS. THE FIRE INSPECTOR ADVISED ME OF THE FORD CRUISE CONTROL RECALL AND SAID HE COULD FIND NO OTHER POSSIBLE CAUSE FOR THE FIRE IN THE ENGINE COMPARTMENT AS THERE WERE NO LEAKS OF ANY KIND AND NO RECENT REPAIRS IN THE ENGINE COMPARTMENT. LOCAL FORD DEALERS HAVE DECLINED TO TELL ME IF MY VIN HAD WARRANTY WORK TO REPAIR THE SWITCH. *TR

THE VEHICLE STALLS ON NUMEROUS OCCASIONS DUE TO LACK OF FUEL. INVESTIGATION PROVED THAT THE INTERIOR PAINT OF THE GAS TANK PEALS BLOCKING THE FUEL PUMP. RESEARCH SHOWS THAT DELAMINATION OF THE GAS TANK IS FREQUENT IN THIS MODEL CAUSING A VERY UNSAFE CONDITION AS THE VAN CAN STOP AT ANYTIME AS IT LOOSES POWER AND PROPULSION DUE TO THE PAINT FLAKES BLOCKING THE FUEL. *TR

TL* THE CONTACT OWNS A 1999 FORD F350. THE CONTACT STATED THAT WHILE DRIVING 60 MPH, THE CONTACT NOTICED THAT THE FUEL TANK WAS DANGLING FROM THE VEHICLE. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC FOR DIAGNOSIS WHERE IT WAS STATED THAT THE FUEL TANK SUPPORT STRAPS WERE RUSTED. THE VEHICLE WAS REPAIRED AND THE MANUFACTURER WAS NOT NOTIFIED. THE APPROXIMATE FAILURE MILEAGE WAS 150,000.

I RECENTLY PURCHASED A USED 24' 1999 WINNEBAGO ITASCA SPIRIT WITH VERY LOW MILEAGE AND AT THAT TIME I NOTICED A SHAKING OR VIBRATION PROBLEM POSSIBLY COMING FROM THE TIRES. I OWNED A MOTOR HOME IN THE PAST AND HAVE SOME EXPERIENCE. THIS MOTOR HOME SAT FOR SEVERAL YEARS SO I ATTRIBUTED THE SHAKING TO THE MEMORY IN THE RUBBER OF FLAT SPOTS ON THE BOTTOM FROM SITTING FOR A LONG TIME THAT USUALLY SMOOTH OUT WHEN DRIVEN ESPECIALLY AFTER 30 OR 40 MILES ON A WARM DAY, BUT AFTER A 400 MILE TRIP IT DIDN'T SMOOTH OUT, IN FACT IT SEEMS TO HAVE WORSENED. BEFORE PURCHASING IT FROM A PRIVATE PARTY I RAN AN INSTAVIN AND CARFAX REPORT AND ONLY DISCOVERED AN UNCOMPLETED NHTSA RECALL #05S28 ON THE SPEED CONTROL ONLY. I THEN SEARCHED SEVERAL FORUMS AND DISCOVERED MANY, MANY REPORTS OF THE SAME PROBLEM WITH THE SHAKING AND LEARNED IT IS DUE TO FAULTY WHEELS AND FORD IS NOT MAKING GOOD THE PROBLEM BUT OFFERED AN EXPENSIVE FIX THAT I UNDERSTAND IS ALSO IFFY. I AM VERY CONCERNED ABOUT MY FAMILY'S SAFETY DRIVING ON THESE DEFECTIVE WHEELS AND FIRST LOOKED INTO REPLACING THE TIRES WHICH I LEARNED ISN'T THE PROBLEM BUT THE FAULTY WHEELS THAT WERE AN OEM FORD PART, SO I WANT TO ADD MY COMPLAINT TO THE MANY YOU ALREADY HAVE AND MAYBE FORD WILL FIX THIS POTENTIALLY SERIOUS SAFETY PROBLEM.

STEERING FELT LOOSE. MECHANIC DETERMINED A NUT ON STEERING COLUMN GOT LOOSE. THIS HAS HAPPENED 2 MORE TIMES.*AK

FORD E-350 AND E-250 VANS, BOTH ARE YEAR,1999 THE ANTILOCK AND BRAKE LIGHTS CAME ON SIMULTANEOUSLY AT A 105K MILES ON EACH. THERE SHOULD BE NO REASON FOR THIS AND I ALSO NOTICED MANY OTHERS WITH THE SAME ISSUES. IT WILL IMPOSE A SAFETY ISSUE BECAUSE I SEEN A WEB SITE MENTIONING HOW TO DISCONNECT DASH LIGHTS FOR BOTH. PLEASE TAKE THIS INTO CONSIDERATION BEFORE AUTO OWNERS START DISCONNECTING WIRE HARNESS.

1999 FORD E350 WITH ONLY 48,000 MILES HAS THE BRAKE LINES SO BADLY RUSTED THAT THEY ARE LEAKING BRAKE FLUID. THE VEHICLE CAN'T BE DRIVEN UNTIL ALL THE BRAKE LINES ARE REPLACED. REPLACEMENT PARTS ARE NOT AVAILABLE FROM FORD. I MUST FABRICATE REPLACEMENTS FROM GENERIC PARTS. IT SHOULD BE A REQUIREMENT THAT BRAKE LINES BE MADE FROM STAINLESS STEEL SO THEY CAN'T RUST OUT. THIS IS A CLEAR DANGEROUS CONDITION THAT COULD BE ELIMINATED IF MANUFACTURER WERE REQUIRED TO USE STAINLESS STEEL WHICH WILL NOT RUST. I ALMOST DROVE THROUGH MY GARAGE DOOR WHEN THE BRAKE PEDAL WENT TO THE FLOOR WHEN THE RUSTED BRAKE LINE BURST. I HAD TO JAM ON THE PARKING BRAKE TO STOP THE VEHICLE. THIS HAPPENS WITHOUT WARNING ONE DAY THE BRAKES WORK THE NEXT DAY THEY DON'T. MAKE BRAKE LINES FROM STAINLESS STEEL SO THEY WON'T RUST!! *TR

THE MAIN PROBLEM WITH A VEHICLE OF MINE IS THE SPARK PLUG BLOWING OUT OF THE ENGINE. THIS HAS HAPPENED TWICE, AND THE MANUFACTURER HAS SWEPT IT OFF LIKE NOTHING WAS WRONG. THE VEHICLE IS A 1999 FORD E350 SUPER DUTY VAN WITH A TRITON V10 ENGINE. WHILE SEARCHING ONLINE AS WELL AS TALKING WITH OTHER PEOPLE, THIS ENGINE WAS A BIG FAILURE. I HAVE HEARD OF AT LEAST 122 OF THESE ENGINE HAS HAD THE SAME PROBLEM. FORD CHARGES WELL OVER $3000 EACH TO HAVE THIS FIXED! THIS IS AN OUTRAGE. TO TRY AND CREAT A CLASS ACTION SUITE, WOULD BE WAY TO EXPENSIVE. WHERE IS HELP? CONSUMERS NEED YOU TO HELP US. I HAVE TRIED CONTACTING FORD OVER THE PAST YEAR WITH NO RESPONSE FROM THEM. THIS IS NOT THE ONLY PROBLEM WITH THE VAN. I HAVE HAD THE TRANSMISSION REPLACED TWICE, WITHIN A MONTH OF EACH OTHER, THE WINDSHILED REPLACED FOR A BAD GASKET, FUEL TANK AND PUMP REPLACED, MASS AIR FLOW SENSOR AND I CAN GO ON AND ON. I NEED HELP WITH THIS. THE VAN COST ME $25000. I HAVE PAID WELL OVER $5000 IN REPAIR COSTS. PLEASE HELP. I KNOW OTHER CONSUMERS HAVE HAD THE SAME PROBLEM AND THEY NEED HELP ALSO.*AK

I WAS IN AN ACCIDENT AND MY AIR BAGS DID NOT WORK I HAVE DAMAGE TO FRONT END AND REAR END

ANOTHER CONSUMER HEARD A NOISE IN VEHICLE AND REACHED IN TO TURN VEHICLE OFF. CONSUMER RESTARTED VEHICLE, AND WHEN CONSUMER REACHED IN TO RESTART VEHICLE, AIRBAG DEPLOYED IN HIS FACE WITHOUT REASON.

THE PROBLEM PRESENTED AS A "POPPING" NOISE AS REPORTED BY THE DRIVER, WHENEVER THE BRAKES WERE APPLIED. UPON INVESTIGATION FOR BRAKE SYSTEM PROBLEM THE REPAIR STATION IDENTIFIED THE BROKEN SPRING. THIS COIL SPRING IS BROKEN IN SEVERAL LOCATIONS ALONG THE UPPER COIL, WITH FRAGMENTATION IN LONGITUDINAL AND TRANSVERSE BODY OF THE SPRING MATERIAL. THIS COULD PRESENT A LOSS OF SUSPENSION CONTROL IF THE BREAKAGE WORSENED, OR OCCURRED AT MULTIPLE OTHER LOCATIONS IN THE COURSE OF DEGRADATION. THE VEHICLE HAS BEEN REMOVED FROM SERVICE, AND OTHER UNITS IN THE SAME ORDER HISTORY FOR THIS FLEET ARE BEING INSPECTED. DT

UPON SPEEDS IN EXCESS OF 45MPH, FRONT END VIBRATES AS IF YOU ARE DRIVING AN ORBITAL SANDER ON GRAVEL

CONSUMER SAYS THE DOORS ARE OF POOR CONSTRUCTION, AND UNSAFE DUE TO CHEEP QUALITY. THE PANELS STRUCTURE (SIDE) SEEMS TO BE TOO THIN, LIKE THERE IS NO INSULATION, ALSO IF THE PANELS OF POOR CONST. THAT IS A BIG PROBLEM. UN SAFE.
