STEERING WENT OUT AT 95,000 MILES ON MY DAUGHTER'S 2008 MERCURY MARINER. WE WERE LUCKY THAT SHE OR NO ONE ELSE WAS KILLED OR SERIOUSLY INJURED BECAUSE THE WEATHER WAS BAD AND THE ROADS WERE ICY. SHE STATES THAT SHE COULD BARELY TURN THE WHEEL AND IT TOOK ALL SHE HAD TO TURN AFTER IT WENT OUT, AND, IT SEEMED TO GET EVEN WORSE WHEN SHE STOPPED, SHUT IT OFF AND TURNED IT BACK ON. I ASSUME IT IS A RECURRING ISSUE FROM THE RECALL THAT WAS PERFORMED ON THE VEHICLE BACK IN 2015. I JUST CALLED FORD CUSTOMER SERVICE AND THEY STATE THAT BECAUSE THE RECALL WAS ALREADY PERFORMED, THEY CAN CONFIRM THAT IT WILL NOT BE COVERED. THEY RECOMMENDED THAT I TAKE IT TO A FORD DEALER FOR DIAGNOSIS AND REPAIR FOR A FEE. THE BIGGER ISSUE THAN COST IN MY OPINION IS THE LINGERING SAFETY HAZARD THAT STILL EXISTS. THE COMPONENT FAILED ABOUT A MONTH SHY OF 2 YEARS AFTER THE UPDATE, HOWEVER, AS FAR AS FORD IS CONCERNED, THE ISSUE HAS BEEN RESOLVED. SOMEONE COULD CRASH AND DIE BECAUSE OF THIS KNOWN ISSUE. IS FORD NOT CONCERNED? HOW CAN THEY SLEEP AT NIGHT KNOWING HUNDREDS OF THOUSANDS OF PEOPLE (LIKE MY DAUGHTER) ARE AT RISK. IN MY OPINION, IT IS COMPLETELY UNREASONABLE TO NOT CONDUCT ANOTHER RECALL FOR THE SAFETY OF THEIR CUSTOMERS. SOMEONE WITH MONEY NEEDS TO GET AFTER THEM WITH A LAWSUIT.

MY WIFE AND I WERE DRIVING HOME ON THE INTERSTATE. WE HAD JUST MERGED TO THE PASSING LANE TO ALLOW TRAFFIC MERGING FROM AN ON RAMP TO ENTER THE INTERSTATE A VEHICLE NEXT TO US WAS DOING THE EXACT SPEED AS WE WERE WHICH WAS 72 MPH SET CRUISE CONTROL. I HAD VEHICLES APPROACHING FROM THE REAR AND SINCE I WAS IN THE PASSING LANE DECIDED TO SPEED UP AND GET IN FRONT OF THE CAR BESIDE US I PUSHED THE ACCELERATOR ON OUR 08 MERCURY MARINER WITH A 3.0L ENGINE TO THE FLOOR AND THE CAR ACCELERATED IN FRONT OF THE OTHER CAR, WHEN I LIFTED MY FOOT OFF THE ACCELERATOR THE CAR CONTINUED TO ACCELERATE. I PUSHED ON THE BRAKE ONCE WITH NOTHING CHANGING THE CAR CONTINUED TO ACCELERATE. I PROCEEDED TO PUMP THE BRAKE THREE ADDITIONAL TIMES IN ABOUT 1 SECOND INTERVALS. FINALLY THE ACCELERATOR PEDAL RELEASE AND THE CAR SLOWED DOWN. WE PRECEDED HOME WITHOUT FURTHER INCIDENT. THIS IS A VERY DANGEROUS CONDITION AND HAS RESULTED IN SERIOUS INJURIES AND DEATHS IN EARLIER MODEL YEARS OF FORD ESCAPE, MERCURY MARINER AND MAZDA TRIBUTE VEHICLES. I HAVE HAD FORD VEHICLES MY WHOLE LIFE AND HAVE BEEN WORKING ON VEHICLES FOR MORE THAN THIRTY FIVE YEARS. THIS IS NOT NORMAL AND IS NOT THE ONLY TIME OR VEHICLE THIS HAS HAPPENED TO IN THIS YEAR THERE ARE MANY OTHER SIMILAR PEOPLE THAT HAVE SIMILAR COMPLAINTS ON THESE FORD AND MERCURY SUV'S ON THE INTERNET EX: CARCOMPLAINTS.COM TO NAME JUST ONE. THE INTERNET IS FILLED WITH THESE DANGEROUS COMPLAINTS. WHEN ARE YOU GOING TO LIVE UP TO YOUR NAME AND PUT THE SAFETY ASPECT FIRST,WHEN DEALING WITH THESE TO RICH TO BE BOTHERED BY RECALLS AUTO MANUFACTURERS? *TR

Official recalls
3Sep 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.

Sep 3, 2014
Ford Motor Company (Ford) is recalling certain model year 2005-2008 Ford Escape hybrid electric vehicles manufactured October 13, 2003, to June 20, 2008, and 2006-2008 Mercury Mariner hybrid electric vehicles manufactured June 10, 2005, to June 20, 2008. The coolant pump for the hybrid system may fail resulting in the hybrid electronics overheating.
Consequence & remedy
Consequence: If the hybrid electronics system overheats, it may shut down the powertrain, resulting in a stall-like condition, increasing the risk of a crash.
Remedy: Ford will notify owners, and dealers will inspect and replace the original Motor Electronics Coolant (MEC) Pump with an improved brushless pump, free of charge. The recall is expected to begin on October 27, 2014. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 14S19.
May 29, 2014
Ford Motor Company (Ford) is recalling certain model year 2008-2011 Ford Escape and Mercury Mariner vehicles manufactured August 18, 2006, through September 11, 2010. The affected vehicles have a steering torque sensor that may not be able to properly detect driver steering input. As a result, the system could remove the Electric Power Steering (EPS) assist.
Consequence & remedy
Consequence: If power steering assist is lost, greater driver effort would be required to steer the vehicle at low speeds, increasing the risk of a crash.
Remedy: Ford will notify owners, and dealers will update the software for the power steering control module (PSCM) and the instrument cluster module, free of charge. If a vehicle shows a history of a loss of the torque sensor signal or fault codes relating to the PSCM when the vehicle is brought in for the recall remedy, the affected components will be replaced, free of charge. The recall began on July 18, 2014. Owners may contact Ford customer service at 1-800-392-3673. Ford's number for this recall is 14S05.

2DP15001 · Loss Of Power Steering While Driving
Opened Apr 1, 2015 · Closed Jun 14, 2018
Status: closed (inferred from source dates) · Steering:electric Power Assist System
On May 27, 2014, amended June 2, 2014, Ford Motor Company (Ford) submitted a Defect Information Report (DIR) to NHTSA describing a safety defect that may result in a sudden loss of power steering assist while driving in approximately 746,067 model year (MY) 2008 through 2011 Ford Escape vehicles equipped with electric power assisted steering (NHTSA 14V-284, Ford 14S05). Ford's DIR described the defect condition as a poor signal to noise ratio [SNR] in the torque sensor within the Electric Power Assisted Steering (EPAS) system [which] does not allow the PSCM to determine the driver's steering input. When the system detects this fault condition, it transitions the EPAS system to the fail-safe/manual steering mode.Ford's DIR indicates that loss of power steering assist while driving would require higher steering effort at lower vehicle speeds, which may result in an increased risk of a crash.Ford's remedy instructs dealers to check the Power Steering Control Module (PSCM) for Diagnostic Trouble Codes (DTCs) to determine the proper repair procedure. If no DTCs are present, dealers are to update the PSCM and instrument cluster module software. The updated PSCM software changes the torque sensor fault strategy so that the SNR condition does not result in a loss of power steering assist while driving.In addition, audible and visual warnings are provided for torque sensor faults.If DTCs indicating faults in the torque sensor, PSCM or Power Steering Motor (motor) are present in the initial recall inspection, the dealer performs the following repairs: 1) replaces the torque sensor for torque sensor faults (DTC B2278); or 2) replaces the steering column for faults related to the PSCM (DTC B1342) or motor (DTC B2277).Continued in attachment pages

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
