TIRE VALVE CRACKING
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

SINCE I PURCHASED IN 2009, ENGINE KILLS ANYTIME, MOSTLY WHEN GAS PEDAL NOT PRESSED. PULLING OUT OF PARKING LOTS, SITTING AT RED LIGHTS, OR LETTING OFF GAS ON INTERSTATE, ENGINE JUST KILLS. SOMETIMES FEELS LIKE A JOLT. I HAVE TO PUT THE SHIFT IN NEUTRAL AND RESTART THE ENGINE. RECORDS OF ALL VISITS FOR THE PROBLEM AT DEALERSHIP. NEVER COULD SOLVE PROBLEM, BUT TOO UNSAFE TO DONATE TO MY GRANDSON. IF SOMETHING WERE TO HAPPEN TO HIM BECAUSE OF A DEFECT THAT WAS NEVER FOUND, I DON'T KNOW WHAT I'D DO. CANNOT CHECK TRANSMISSION FLUID LEVEL. SEALED. I DO HAVE SOME FLUID STAINS ON MY DRIVEWAY. FOR YEARS I'VE REPORTED TO THE DEALERSHIP AND SPECIFIED THE CONCERN FOR SAFETY BUT TO NO AVAIL. IT KILLS ANYTIME. MAY NOT DIE FOR A WEEK, OR TOMORROW, OR EVEN A MONTH. NO PARTICULAR PATTERN. FEELS LIKE A TRANSMISSION PROBLEM. IF I'M SITTING IN A PARKING LOT WITH MOTOR RUNNING, SOMETIMES IT JUST KILLS. IT'S THE SHIFTING TO NEUTRAL WHILE DRIVING ON HIGHWAYS AND STREETS TO RESTART WHILE MOVING I'M WORRIED ABOUT. I'VE HAD SEVERAL MECHANICS CLAIM THEY FIXED IT BUT TO NO AVAIL. PLEASE GIVE ME SOME DIRECTION. ALL THE SHOPS I'VE GONE TO ARE REPUTABLE BUSINESSES. ONE MECHANIC SAID THE ELECTRONIC BRAIN (COMPUTER BOX) MIGHT BE CAUSING AND SAID TO SEND IT TO MERCURY FOR RECALCULATION. I DON'T KNOW ABOUT THAT. MOST OF THE READ OUTS ARE EPA RELATED.

Manufacturer communications
A bulletin sent by a manufacturer to its dealers. Not a recall, and repairs are not necessarily free.
EQUIPMENT
All accessory stick-on keyless entry keypads come with a wallet card containing the master code. If the accessory keypad was factory installed, this card will be placed in the glove box and should be handed to the vehicles owner during initial delivery. Unlike the integrated (wired) factory keypad, the accessory keypad master code cannot be retrieved from the vehicle using a diagnostic scan tool. If the wallet card for an accessory keypad is lost, follow these steps to recover the code. Dealer Key Code access is granted through the Dealer Program Enrollment System (DPES); dealership management can authorize users. The authorized user must go to FMCDealer.com > Parts and Service > Parts Product Line Information > Keys/Entry Devices > Aftermarket Keyless Entry Keypad Code Access. Follow the instructions on the screen to obtain the master code for the accessory keypad.
POWER TRAIN:AUTOMATIC TRANSMISSION
When performing any transmission fluid changes or topoffs involving MERCON SP, MERCON LV has replaced all versions of MERCON SP and can be used going forward. Mixing MERCON LV and MERCON SP in the same transmission is acceptable. After 30-Jun-2023, MERCON SP ATF will no longer be manufactured and will only be available until inventory depletes.
EQUIPMENT; STRUCTURE
Some 2000 and newer Ford, Lincoln and Mercury vehicles equipped with aluminum body panels may exhibit corrosion concerns appearing as bubbled and/or peeling paint with or without accompanying white dust. Panel replacement is recommended. Follow the Service Procedure steps to correct the condition

STEERING
This SKU is a front upper ball joint. The Customer communication requested return of unsold inventory to inspect for ball studs with excessive rotational friction in the ball joint assembly. Excessive friction in the ball joint assembly may cause a perceptible increase in steering effort.
ENGINE; EQUIPMENT
Various vehicles equipped with a 4.6L, 5.4L, 6.8L modular 3 valve engine built on or before 8-Jan-2016 may exhibit symptoms that may include upper end engine noise, rough running, misfire and/or engine damage. If diagnosis leads to only camshaft/camshaft roller follower(s) requiring replacement, replace all of the camshaft roller followers on both banks/cylinder heads with part number 3L3Z-6564-A, not just the faulty roller follower(s). When replacing the camshaft roller followers, refer to Workshop Manual (WSM), Section 303-01.
Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
