AT 3000 MILES THE ENGINE WAS REPLACED DUE TO A KNOCK IN THE ENGINE. AT 11,000 MILES THERE WAS A SEVERE VIBRATION IN THE DRIVE TRAIN AT 65 MPH WITH THE VECHILE UNDER LOAD - FORD COULDN'T IDENTIFY THE PROBLEM AND HAD NO FIX. AT 12,500 MILES THE TORQUE CONVERTER FAILED RESULTING IN THE VECHILE STALLING AT STOPS. THE TORQUE CONVERTER AND TRANSMISSION WERE REPLACED. THIS REDUCED THE VIBRATION BUT DID NOT ELIMINATE IT. AGAIN FORD TRIED SEVERAL TIMES BUT COULD NOT IDENTIFY AND CORRECT THE PROBLEM. AT 21,000 MILES THE VECHILE LOST ALL POWER AND WOULD ONLY MOVE BY REVING THE ENGINE (LIKE SEVERE CLUTCH SLIPPAGE ON A MANUAL TRANSMISSION). FORD IS PRESENTLY INVESTIGATING. BOTH FAILURES COULD HAVE RESULTED IN SEVERE ACCIDENTS IF THE DRIVING CONDITIONS HAD BEEN SLIGHTLY DIFFERENT AT THE TIME OF THE FAILURES. THE PROBLEM APPEARS TO ME TO BE IN THE COMPUTER CONSTROL SYSTEM FOR THE TRANSMISSION RESULTING IN POSSIBLY THE SECOND FAILRE OF THE TRANSMISSION.

TIRES
MY TIRE FAILED ON MY 2007 FORD EXPEDITION EL MILEAGE 18000, TIRES ARE THE ORIGINAL/FACTORY INSTALLED PIRELLI SCORPION P255/70R18. THE TIRE WENT FLAT AT FREEWAY SPEED AND THE SIDEWALL IS NOW DAMAGED BEYOND REPAIR. UNDER FURTHER INVESTIGATION I FIND THAT THE TIRE DOES NOT HAVE ANY PUNCTURE AND IT IS A CRACKED VALVE STEM THAT IS CAUSING THE LEAK. EVEN WITH THE SIDEWALL DAMAGE THE TIRE TAKES AIR AND THE ONLY LEAK IS COMING FROM THE LEAKING VALVE STEAM. THE FORD DEALER WILL BE REPLACING THE TIRE AT MY COST. I FEEL THIS IS A MANUFACTURER ISSUE AND KNOW THERE IS A RECALL ON THESE AND FORD SHOULD BE REPLACING THE TIRE FOR FREE AND CHECKING ALL OTHER VALVES ON THE VEHICLE. I SPOKE WITH CLAY AT TECH INTERNATIONAL AND HE EXPLAINED THAT FORD HAS NOT RECALLED THESE TIRES BUT TECH INTERNATIONAL HAS RECALLED "AFTER MARKET" TIRE REPLACEMENTS. FORD NEEDS TO TAKE IMMEDIATE ACTION ON THIS TO PREVENT ANY FUTURE FAILURES THAT COULD LEAD TO SERIOUS ACCIDENTS. LUCKILY MY FAILURE DID NOT CAUSE AN ACCIDENT BECAUSE IT WAS A REAR TIRE AND I WAS ABLE TO PULL OVER THE VEHICLE, PREVENTING AN ACCIDENT BUT I DID BEGIN TO LOOSE CONTROL. *TR
