WHEN I AM DRIVING THE CAR THE SEAT WILL MOVE BACK ON IT'S OWN VOLITION INTO EXIT POSITION. THIS HAPPENS WHEN IT GOES OVER A BUMP OR IF THE KEY IS JIGGLED IN THE IGNITION. IT HAPPENED IN MULTIPLE SITUATIONS LAST WEEK. VERY FRIGHTENING AS I HAVE TO SCRAMBLE TO REACH THE BRAKE AND ALSO MOVE THE SEAT BACK INTO POSITION. I HAVE TURNED OFF THE EASY EXIT OPTION SO THIS HAS STOPPED IT BUT IT UPSETS ME THAT I NO LONGER HAVE A FEATURE THAT I PAID FOR.
WHILE DRIVING DRIVER SEAT GOES BACKWARD AND INTERIOR LIGHTS GOES ON WITH OUT USING OR PUSHING NO INSTRUMENTS

AFTER APPROXIMATELY 90,000 MILES THE DOME LIGHTS TURNED ON AND AUTOMATIC SEATS MOVE BACK WHILE DRIVING. THIS ISSUE PERSISTS AND OFTEN OCCURS SEVERAL TIMES. THERE ARE SEVERAL COMPLAINTS OF THIS ISSUE FOUND ONLINE. IT IS NOT DUE TO A HEAVY KEY CHAIN AS I ONLY HAVE THE FOB AND KEY ATTACKED. THIS IS A SAFETY ISSUE AS THE SEATS PULL THE DRIVER AWAY FROM THE PEDALS AND STEERING WHEEL. INVESTIGATE! RECALL!

WHILE DRIVING, THE DRIVERS POWER SEAT WILL MOVE TO THE "OPEN DOOR POSITION" CAUSING MY FEET TO BE TOO FAR FROM THE PEDALS. THIS IS EXTREMELY DANGEROUS. I HAVE SEEN MANY REPORTS REGARDING THIS ISSUE.
I ALSO HAVE THE SAME ISSUE WITH THE IGNITION CAUSING THE SEATS TO MOVE THE EASY EXIT POSITION. THIS HAPPENS CONSTANTLY WHILE DRIVING AND IS VERY UNSAFE. THE INTERIOR LIGHTS COME ON AS IF THE KEY WAS TURNED OFF AND REMOVED FROM THE IGNITION, ALSO CAUSING THE SEAT TO MOVE THE EXIT POSITION. WHEN THIS HAPPENS, I AM UNABLE TO REACH …

I ALSO HAVE THE SAME ISSUE WITH THE IGNITION CAUSING THE SEATS TO MOVE THE EASY EXIT POSITION. THIS HAPPENS CONSTANTLY WHILE DRIVING AND IS VERY UNSAFE. THE INTERIOR LIGHTS COME ON AS IF THE KEY WAS TURNED OFF AND REMOVED FROM THE IGNITION, ALSO CAUSING THE SEAT TO MOVE THE EXIT POSITION. WHEN THIS HAPPENS, I AM UNABLE TO REACH THE PEDALS AND SCRAMBLE TO CORRECT THE ISSUE. I SEE WHERE THIS IS HAPPENING TO QUITE A FEW OTHER OWNERS. SOMETHING NEEDS TO BE DONE BEFORE SOMEONE IS SERIOUSLY HURT OR KILLED.
WHILE THE VEHICLE IS IN MOTION, THE POWER DRIVERS SEAT MOVES SPONTANEOUSLY WHILE DRIVING WITH NO WARNING BACK INTO THE ENTRY/EXIT POSITION MAKING IT DIFFICULT TO REACH THE BRAKE/ACCELERATOR PEDALS.
THE DRIVER SEAT MOVES BACK WHEN DRIVING. NO SET PATTERN. SOMETIMES AS MANY AS 10 TIMES WHEN DRIVING AND OTHER TIMES 1 TIME. NO SET PATTERN. JUST HAPPENS

1PE08060 · Tire Valve Cracking
Opened Oct 14, 2008 · Closed Apr 9, 2009
Status: closed (inferred from source dates) · Tires:valve
ON OCTOBER 14, 2008, ODI OPENED PE08-060 TO INVESTIGATE ALLEGATIONS OF CRACKED AND LEAKING SNAP-IN TIRE VALVES IN MODEL YEAR (MY) 2007 VEHICLES MANUFACTURED BY FORD MOTOR COMPANY.THE VALVES WERE SUPPLIED TO FORD BY TOPSEAL AUTO-PARTS, A SUBSIDIARY OF THE SHANGHAI BAOLONG AUTOMOTIVE CORPORATION IN CHINA.VALVES MADE BY TOPSEAL FOR AFTERMARKET SALE WERE THE SUBJECT OF TWO RECENT SAFETY RECALLS BY TECH INTERNATIONAL (08T-018) AND DILL AIR CONTROLS (08T-028), THE LATTER OF WHICH WAS INVESTIGATED BY ODI IN PE08-036 AND EA08-022.THE DEFECT CONDITIONS ADDRESSED BY THE AFTERMARKET TIRE VALVE RECALLS BOTH INVOLVED INADEQUATE RESISTANCE TO OZONE CRACKING DUE TO ISSUES WITH THE SUPPLY OF ANTI-OZONANT CHEMICALS TO TOPSEAL FOR A PERIOD FROM JULY TO MID-NOVEMBER 2006.THE AFTERMARKET VALVES WERE COMPOUNDED WITH A BLEND OF EPDM AND NATURAL RUBBER, USING A RELATIVELY LOW PERCENTAGE OF EPDM (EPDM PROVIDES INHERENT RESISTANCE TO OZONE CRACKING).HENCE, THE NEED FOR ANTI-OZONANT CHEMICALS AND THE PROBLEMS WITH CRACKING WHEN THOSE CHEMICALS WERE MISSING OR OUT OF SPECIFICATION IN SOME LOTS OF VALVES.BOTH RECALL CAMPAIGNS INVOLVED INSPECTION PROGRAMS TO IDENTIFY AND REPLACE VALVES WITH VISIBLE SURFACE CRACKING.ALTHOUGH THE TOPSEAL VALVES SUPPLIED TO FORD ALSO APPEAR TO HAVE BEEN AFFECTED BY THE ANTI-OZONANT SUPPLY ISSUES IN MID TO LATE-2006, FORD INDICATED THAT ITS VALVES WERE MADE AT A DIFFERENT TOPSEAL PRODUCTION LINE AND WERE COMPOUNDED WITH A HIGHER PERCENTAGE OF EPDM RUBBER TO MEET MORE STRINGENT SPECIFICATIONS FROM FORD.ODI'S ANALYSIS OF COMPLAINT AND WARRANTY DATA PROVIDED BY FORD SHOWED THAT PROBLEMS WITH CRACKED TIRE VALVES WERE SIGNIFICANTLY HIGHER FOR MY 2007 VEHICLES PRODUCED FROM DECEMBER 2006 THROUGH MARCH 2007.FORD RESPONDED BY IMPLEMENTING CHANGES IN ITS MATERIAL SPECIFICATIONS FOR SNAP-IN RUBBER TIRE VALVES AND ALSO INCREASING THE QUALITY AND ACCEPTANCE STANDARDS FOR VALVES IMPORTED FOR USE IN ITS VEHICLES.WHILE THE COMPLAINT AND WARRANTY CLAIM RATES ARE ELEVATED FOR SUBJECT VEHICLES PRODUCED FROM DECEMBER 2006 THROUGH MARCH 2007, THE RATES OF LEAKING VALVES ARE WELL BELOW ONE PERCENT OF PRODUCTION FOR EACH OF THE PEAK MONTHS FOR ALL OF THE AFFECTED MODELS.A SUBSTANTIAL MAJORITY OF THE SUBJECT VEHICLES ARE EQUIPPED WITH TIRE PRESSURE MONITORING SYSTEMS (TPMS) WHICH WARN THE DRIVER WHEN ANY TIRE PRESSURES DROPS BELOW 25 PERCENT OF RECOMMENDED INFLATION PRESSURE. AS OUTLINED IN A LETTER TO ODI DATED APRIL 6, 2009, FORD HAS AGREED TO SEND LETTERS TO OWNERS OF CERTAIN MY 2007 AND 2008 FORD, LINCOLN AND MERCURY VEHICLES TO PROVIDE INFORMATION ABOUT THE CRACKING CONCERN. LETTERS WILL BE SENT TO OWNERS OF VEHICLES BUILT FROM NOVEMBER 2006 THROUGH MAY 2007.OWNERS CAN OPT FOR A FREE DEALER INSPECTION.VALVES EXHIBITING SURFACE CRACKS OR AIR LEAKAGE RELATED TO OZONE ATTACK WILL BE REPLACED BY FORD UNDER ITS NORMAL WARRANTY TERMS.FORD EXPECTS TO SEND THE LETTER BY APPROXIMATELY MID-MAY 2009. BASED ON THE USE OF TPMS IN THE MAJORITY OF SUBJECT VEHICLES AND THE RELATIVELY LOW RATES OF REPAIRS ASSOCIATED WITH LEAKING VALVES AND RESULTANT TIRE DAMAGE, ODI BELIEVES THAT THE ACTIONS FORD HAS AGREED TO TAKE WILL PROVIDE EFFECTIVE AND EXPEDITIOUS RESOLUTION FOR VEHICLES THAT WERE BUILT DURING THE PERIOD WHEN VALVES WITH INADEQUATE RESISTANCE TO OZONE CRACKING WERE MOST LIKELY TO HAVE BEEN USED IN VEHICLE PRODUCTION.FURTHER INVESTIGATION OF THIS MATTER WOULD NOT BE AN EFFICIENT ALLOCATION OF AGENCY RESOURCES.ACCORDINGLY, THIS INVESTIGATION IS CLOSED.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT A SAFETY-RELATED DEFECT DOES NOT EXIST.THE AGENCY WILL CONTINUE TO
