ABOUT 2 MONTHS AGO, THERE BEGAN A STRONG SMELL OF GASOLINE IN MY GARAGE IMMEDIATELY AFTER FILLING MY GAS TANK. AFTER THIS HAPPENING SEVERAL OTHER TIMES, I HAD THE CAR TESTED FOR A FUEL LEAK. A SMOKE TEST WAS PERFORMED AND NO LEAK WAS FOUND. UPON SEARCHING AN ANSWER TO THIS PROBLEM, IT HAS COME TO MY ATTENTION THAT THIS IS A COMMON ISSUE IN LINCOLN MKX AND FORD EDGE SUV'S MADE IN 2007 AND AFTER. THERE ARE MANY IN ONLINE FORUMS WHO HAVE BEEN TOLD THE UPPER PART ("NECK") OF THE GAS TANK HAS CORRODED CAUSING FUEL TO SPRAY ONTO THE CHASIS. THIS IS ALSO MY EXPERIENCE, AS I HAVE BEEN TOLD THE SAME THING BY MY MECHANIC. I BELIEVE THIS IS A SAFETY CONCERN. THE FUMES AFTER FILLING THE TANK IS NOT TOLERABLE AND NOT SAFE. WHETHER OR NOT THIS IS A FIRE HAZARD, I CAN ONLY SPECULATE. *TR

PE09031 · Front Suspension Lower Ball Joint

Opened Jul 13, 2009 · Closed Nov 19, 2009

Status: closed (inferred from source dates) · Suspension:front:control Arm:lower Ball Joint

ON JULY 13, 2009, THE OFFICE OF DEFECTS INVESTIGATIONS (ODI) OPENED PRELIMINARY EVALUATION PE09-031 TO INVESTIGATE ALLEGATIONS OF FRONT LOWER BALL JOINT SEPARATION IN MODEL YEAR (MY) 2007 AND 2008 FORD EDGE AND LINCOLN MKX VEHICLES.THE INVESTIGATION WAS BASED ON THREE OWNER COMPLAINTS ALLEGING THAT THE FRONT LOWER BALL JOINT SEPARATED AND CAUSED THE FRONT SUSPENSION TO COLLAPSE WHILE DRIVING.ODI ALSO IDENTIFIED INFORMATION RELATED TO THE ALLEGED DEFECT IN EARLY WARNING DATA SUBMITTED BY FORD.PRELIMINARY ANALYSIS INDICATED THAT THE FAILURES WERE RELATED TO THE PINCH BOLT USED TO SECURE THE FRONT LOWER BALL JOINT STUD TO THE STEERING KNUCKLE.ONE COMPLAINT ALLEGED THAT A CRASH OCCURRED WHICH RESULTED IN A MINOR INJURY.HOWEVER, NO ADDITIONAL INFORMATION COULD BE OBTAINED TO SUPPORT THIS CLAIM.INFORMATION PROVIDED BY FORD IN RESPONSE TO ODI'S INFORMATION REQUEST LETTER FOR PE09-031 INDICATE THAT IN EARLY MY 2007 PRODUCTION THERE WERE SOME ISSUES WITH THE FRONT LOWER CONTROL ARM BALL JOINT ASSEMBLY PROCESS.THE PINCH BOLTS USED WERE HAND STARTED AND HAD THE POTENTIAL TO CROSS THREAD AND NOT ACHIEVE PROPER CLAMP LOAD, POTENTIALLY RESULTING IN A LOOSE JOINT.IN NOVEMBER 2007, CHANGES WERE IMPLEMENTED TO CHASE AND CLEAN THE FIRST SIX THREADS OF THE BOLT TO PROVIDE EASIER HAND STARTING OF THE NUT AND ENSURE GOOD THREAD ENGAGEMENT BEFORE TIGHTENING. FORD ALSO IDENTIFIED ONGOING CONCERNS WITH THE POWER TRANSMISSION UNIT (PTU) SEALS AND FRONT SUSPENSION HYDRO-BUSHINGS ON THE SUBJECT VEHICLES, WHICH BOTH REQUIRE DISASSEMBLY OF THE FRONT LOWER BALL JOINT TO REPAIR.IF THE BALL JOINT IS NOT PROPERLY REASSEMBLED FOLLOWING SUCH SERVICE, THE JOINT MAY SEPARATE IN LATER SERVICE.FORD HAS PROVIDED ADDITIONAL INSTRUCTIONS AND NEW PINCH BOLTS TO THE PTU REPAIR KIT TO IMPROVE THE JOINT REASSEMBLY PROCESS. ODI'S ANALYSIS OF FAILURE DATA IDENTIFIED 31 INCIDENTS OF JOINT SEPARATION (WITH 12 SPECIFICALLY STATING THAT THEY OCCURRED WHILE DRIVING).REPAIR RECORDS FOR THESE 31 VEHICLES SHOWS THAT 28 INVOLVE SEPARATION OF THE JOINT ON THE PASSENGER (RIGHT) SIDE, WHICH IS THE SIDE THAT MUST BE DISASSEMBLED FOR PTU SERVICE.TWENTY-THREE OF THESE WERE FOUND TO HAVE BEEN PREVIOUSLY DISASSEMBLED FOR CONTROL ARM BUSHING SERVICE, PTU SERVICE OR OTHER TRANSMISSION REPAIR. THE EIGHT CLAIMS THAT DID NOT INVOLVE PRIOR SERVICE REPAIRS REQUIRING JOINT DISASSEMBLY ALL OCCURRED VERY EARLY IN VEHICLE LIFE, INDICATING THAT IT IS UNLIKELY THAT ANY JOINTS MANUFACTURED WITH LOOSE PINCH BOLTS ARE STILL IN SERVICE.ALL OF THESE JOINTS FAILED WITHIN 6 MONTHS IN SERVICE AND 10,000 MILES (THE MAXIMUM FAILURE MILEAGE IS 8,097 MILES).THERE HAVEN'T BEEN ANY SUCH FAILURES (I.E., NOT INVOLVING PRIOR SERVICE/DISASSEMBLY) SINCE DECEMBER 2008.THE RATE FOR INCIDENTS THAT DID NOT OCCUR FOLLOWING SERVICE AND, THUS, MAY BE RELATED TO THE MANUFACTURING PROCESS ISSUES IDENTIFIED BY FORD IS VERY LOW (2.5 PER 100,000 VEHICLES) AND THESE INCIDENTS OCCURRED VERY EARLY IN THE LIFE OF THE VEHICLES AND ARE NOT SHOWING A CONTINUING FAILURE TREND.ACCORDINGLY, THIS INVESTIGATION HAS BEEN 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 MONITOR COMPLAINTS AND OTHER INFORMATION RELATING TO THE ALLEGED DEFECT IN THE SUBJECT VEHICLES AND TAKE FURTHER ACTION IN THE FUTURE IF WARRANTED.

PE08060 · 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
