I PURCHASED THE VEHICLE WITH 6,000 MILES ON IT. I KEPT UP MY NORMAL MAINTANCE ON THE VEHICLE AND REPLACED THINGS WHEN NEEDED. AT APPROXIMATELY 42,000 MY TRANSMISSION WOULD NO LONGER SHIFT THE GEARS. THE VEHICLE WAS BROUGHT TO WALLACE DEALERSHIP OF WHICH THEY KEPT MY VEHICLE FOR ALMOST 2 WEEKS. THEY EXPLAINED THEY DID AN OVERHAUL OF THE TRANSMISSION AND FIXED REPAIRS ON IT SO THAT THEIR WOULD BE NO FURTHER PROBLEMS WITH TRANSMISSION LATER ON DOWN THE ROAD. NOW AT 84,735 MILES LATER, I AM ONCE AGAIN HAVING TRANSMISSION PROBLEMS AND MY VEHICLE WILL NOT GO INTO GEAR. BECAUSE I AM OUT OF WARRANTY MY VEHICLE WILL SIT UNTIL I CAN MAKE THE REPAIRS AS A TRANSMISSION REPLACEMENT IS NOT A CHEAP EXPENSE. THIS IS A SERIOUS PROBLEM WITH IN THIS CAR AND DESERVES EXTREME PRIORITY OF INVESTIGATION ON A RECALL FOR THIS YEAR, MAKE, AND MODEL OF VEHILE. I AM RECEIVING NO HELP FROM THE FORD COMPANY AND I AM FINDING IT EXTREMELY DIFFICULT THAT THIS PROBLEM IN THIS VEHILCE HAS NOT BEEN RESOLVED OR DEALT WITH. I HAVE HAD A PRIVATE TRANSMISSION COMPANY EXAMINE MY VEHILCE (HAS NOT TOUCHED IT), OF WHICH THEY DISCOVERED, THE INTERNAL FILTER IS CLOGGING THE CVT (CONSTANT VELOCITY TRANSMISSION) FOR WHICH SOMETHING WILL CONTINIOUSLY BREAK IN THE FILTER OR WHERE THE FILTER IS HELD CAUSING THIS TO HAPPEN. I WAS ALSO ADVISED THERE WAS NOTHING I COULD HAVE DONE MAINTANCE WISE OR PERSONAL USE OF DRIVING THAT COULD HAVE CAUSED THIS TO HAPPEN. *TR

I HAVE A 2007 MERCURY MARINER I PURCHASED IN APRIL 2007. THE VEHICLE HAS BEEN IN THE SHOP 4 TIMES NOW. 3 OF THE 4 TIMES BECAUSE SOMETHING HAS "GONE OUT" ON THE VEHICLE I.E. THE GAS PEDAL, THE WHEEL BEARINGS, THE TENSION PULLEY. I ALSO FOUND OUT FROM THE DEALERSHIP THAT THAT MANUFACTURER NEVER PUT THE BOLTS ON THE TOP OF MY ENGINE TO COVER THE SPARK PLUGS. I CONTINUE TO HAVE A PROBLEM. THESE LAST THREE INCIDENTS HAVE BEEN WITHIN THE LAST MONTH AND A HALF MY VEHICLE HAS BEEN IN THE SHOP GETTING NEW PARTS. I HAVE ALWAYS BOUGHT USED. THIS IS THE FIRST VEHICLE I HAVE EVER PURCHASED A NEW VEHICLE AND I FIND IT HARD TO BELIEVE IT SHOULD HAVE THIS MANY PROBLEMS. EVERYTHING SO FAR IS COVERED UNDER WARRANTY, BUT IN 1,000 MILES I HAVE NO WARRANTY. I CAN'T IMAGINE HOW MUCH IT IS GOING TO COST IF SOMETHING ELSE "GOES OUT" ON MY BRAND NEW VEHICLE. *TR

15V606000 · Power Train:automatic Transmission:gear Position Indication (prndl); Power Train:automatic Transmission:lever And Linkage:floor Shift

Sep 29, 2015

Ford Motor Company (Ford) is recalling certain model year 2001-2008 Ford Escape and Mercury Mariner vehicles manufactured March 31, 2001, to September 1, 2009. The affected vehicles are equipped with either a 2.3L or 3.0L engine and have had their CD4E transmission replaced with remanufactured one that was rebuilt between June 11, 2015 through July 15, 2015. These service repair part transmissions have a shift lever bolt that may not be properly tightened. As a result, the shift control lever could disengage from the transmission without warning.

Consequence & remedy

Consequence: If the shift lever disengages from the transmission, a driver may be unable to shift gear positions and the indicated shift position may not represent the gear position the vehicle is in. Should a disengagement occur while the vehicle is being driven, when the driver goes to stop and park the vehicle, the gear selection indicator may show that the transmission is in the "PARK" position, but the vehicle transmission may not actually be in the "PARK" gear position. If the vehicle is not in the "PARK" position there is a risk the vehicle will roll away as the driver and other occupants exit the vehicle or anytime thereafter. A vehicle rollaway increases the risk of injury to exiting occupants and bystanders.

Remedy: Ford will notify owners, and dealers will inspect the transmissions and either tighten the manual shift lever bolt or replace the manual shift lever assembly. These repairs will be performed free of charge. The recall began on October 23, 2015. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 15S28.

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
