WHILE TRAVELING AT 45 MPH ON A BUSY ROAD, THE ENGINE STOPPED RESPONDING TO THE ACCELERATOR AND BEGAN DECELERATING. THE THROTTLE/POWER-TRAIN WARNING LIGHT WAS ACTIVATED. I HAD TO PULL OVER THE THE SHOULDER OF THE ROAD TO AVOID BEING HIT BY OTHER TRAFFIC. THE CAR BEGAN JERKING FORWARD AS THOUGH IT WAS TRYING TO ACCELERATE ON ITS OWN. I SHUT OFF THE ENGINE FOR A MINUTE AND ONCE I RESTARTED THE CAR, THE WARNING LIGHT WAS NO LONGER ILLUMINATED. THE NEXT DAY (6/23/2013) I DROVE TO MY CLOSEST FORD DEALER AND THEY DIAGNOSED THE PROBLEM AS A FAULTY THROTTLE BODY. THE SERVICE ADVISOR INFORMED ME THAT THE PART WAS CURRENTLY BACKORDERED AND THAT THEY HAD 15 OTHER FORD VEHICLES CURRENTLY WAITING FOR INVENTORY TO ARRIVE. THE COST OF REPAIR IS $473. THE MECHANIC CLEANED OUT THE CARBON FROM MY THROTTLE BODY AS A TEMPORARY FIX UNTIL THE PART ARRIVED. TWO DAYS LATER (6/25/2013), AS I WAS DRIVING 55 MPH, THE SAME PROBLEM OCCURED AND I WAS FORCED TO PULL OVER AND RESTART MY VEHICLE. WHILE DRIVING BACK TO THE FORD DEALERSHIP THE NEXT MORNING TO GET A RENTAL CAR, MY CAR STOPPED RESPONDING AS I WAS CROSSING TRAIN TRACKS (AND I WAS ABLE TO RESTART THE VEHICLE). NOW MY CAR IS CURRENLY SITTING AT THE FORD DEALERSHIP AND I AM PAYING AN ADDITIONAL $33 A DAY FOR A RENTAL CAR WHILE I WAIT FOR THE PART TO ARRIVE (ESTIMATED TO BE 10-13 DAYS). NHTSA ACTION # DP12006. *TR

ON SUNDAY, JUNE 16, 2013, I WAS DRIVING NEAR TOPEKA, KANSAS, IN A SUBURBAN AREA WITH MY WIFE, 5 YEAR OLD DAUGHTER & 6 MONTH OLD SON IN OUR 2009 FORD ESCAPE. WHILE DRIVING APPROXIMATELY 25 MPH THE VEHICLE STALLED WHILE DRIVING. LUCKILY WE WERE NOT ON A HIGH TRAFFIC STREET SO WE WERE ABLE TO PULL OVER TO THE SIDE OF THE ROAD, SHUT OFF THE VEHICLE, AND RESTART THE CAR SUCCESSFULLY. THE ESCAPE CONTINUED ON WITHOUT ISSUE BACK HOME TO LAWRENCE, KANSAS. THE VEHICLE WAS DRIVEN AROUND LAWRENCE WITHOUT ANY ISSUE UNTIL FRIDAY, JUNE 21, 2013. ON THIS DATE MY WIFE HAD TO COMMUTE FROM LAWRENCE TO KANSAS CITY, KANSAS, FOR WORK-RELATED TRAINING. ON HER TRIP TO KANSAS CITY (KC) THE VEHICLE STALLED WHILE DRIVING AT HIGHWAY SPEED (60+ MPH). SHE WAS SUCCESSFUL RESTARTING THE VEHICLE BUT IT STALLED ONCE AGAIN WHILE IN KC. SHE DROVE THE ESCAPE TO SHAWNEE MISSION FORD TO SEE IF DIAGNOSTICS COULD BE RUN ON THE VEHICLE, BUT THERE WAS NOT ENOUGH TIME LEFT IN THE DAY TO PERFORM THE FULL DIAGNOSTICS. A SERVICE TECHNICIAN TEST-DROVE THE VEHICLE AND WHILE DRIVING IT STALLED ONCE AGAIN. BECAUSE CARSEATS FOR OUR TWO CHILDREN WERE LOCATED IN THE ESCAPE, MY WIFE HAD TO DRIVE FROM KC BACK TO LAWRENCE SO OUR FAMILY WOULD HAVE THESE ITEMS ON HAND. WHILE DRIVING FROM KC TO LAWRENCE THE VEHICLE STALLED ONCE AGAIN AT HIGHWAY SPEED (60+ MPH). ONCE BACK IN LAWRENCE THE VEHICLE WAS DROPPED OFF AT LAIRD NOLLER FORD, AND ON SATURDAY, JUNE 22, 2013, IT WAS DETERMINED BY THEIR SERVICE STAFF THAT THE THROTTLE BODY WAS DEFECTIVE. THIS PART IS CURRENTLY ON NATIONAL BACKORDER, SO WE COULD BE WITHOUT OUR PRIMARY FAMILY VEHICLE FOR MORE THAN 3 WEEKS. THIS WILL RESULT IN HARDSHIP ON THE FAMILY AND COULD RESULT IN MAJOR FINANCIAL COSTS IF A RENTAL VEHICLE IS NEEDED FOR THE ENTIRE PERIOD WE ARE WITHOUT OUR PRIMARY FAMILY VEHICLE AND COULD HAVE RESULTED IN SERIOUS INJURY OR DEATH AS A RESULT OF THIS DEFECT. *TR

THE WRENCH ICON CAME ON. I WAS ABLE TO BASICALLY CRAWL BACK TO MY HOME. IT FELT LIKE IT WOULD IF U PUT THE CAR IN NEUTRAL WHERE IT WOULD JUST COAST SLOWLY. THE NEXT DAY I STARTED THE CAR AND IT WENT BACK TO NORMAL. IT HAPPENED AGAIN A FEW DAYS LATER & I TOOK IT TO FORD. THEY SAID NOTHING WAS WRONG (NO CODE ON COMPUTER). THAT VISIT COST ME $497.89 THIS HAPPENED AGAIN ON 06-20-13 AGAIN DRIVING LOCALLY MAYBE 25 MI/HR.& TOOK TO FORD. AFTER RESEARCHING ONLINE I SEE IT'S A COMMON PROB. I HAD THEM CHG THE THROTTLE BODY. (MY BOTHER IS A MECHANIC) OF COURSE MY WARRANTY DIDN'T COVER THIS PROB. THAT VISIT WAS ANOTHER $368.49. THIS CAR HAS 23K MI ON IT. I HOPE THIS PROBLEM HAS BEEN FIXED. *TR

I PANIC BECAUSE I WAS ON A STREET WHERE THERE WAS NO AREA TO PULL OFF THE ROAD. I LOOKED IN THE REARVIEW MIRROR TO MAKE SURE THAT THERE WERE NO OTHER CARS BEHIND ME AND PUT ON MY HAZARD LIGHTS AND TURNED OFF THE ENGINE. AFTER ABOUT 30 SECONDS I TURNED THE ENGINE OVER AND IT SPUTTERED TO LIFE, BUT THEN THE WRENCH WARNING LIGHT ILLUMINATED AGAIN AND I COULD NOT ACCELERATE. CARS WERE COMING BEHIND ME AND I TRIED MY BEST TO GIVE THEM ROOM TO DRIVE BY, WHICH WAS HARD AS THE RIGHT SIDE OF THE STREET WAS BUMPER TO BUMPER WITH PARKED CARS. AFTER THE CARS PASSED ME, I TURNED OFF THE ENGINE AGAIN AND WAITED ABOUT 30-45 SECONDS AND THE ENGINE CAME TO LIFE AND I WAS ABLE TO DRIVE HOME WITHOUT ANOTHER INCIDENT. *TR

APPROXIMATELY ONE MONTH AGO, WHILE SLOWING TO MAKE A RIGHT-HAND TURN, THE VEHICLE SEEMED TO LOSE ALL POWER; NO ACCELERATION, ETC. I MANAGED TO GET ON THE SIDE OF THE ROAD, PUT THE VEHICLE IN PARK, AND TURNED THE ENGINE OFF. WHEN I RESTARTED THE ENGINE, EVERYTHING SEEMED FINE. ABOUT 2 WEEKS LATER WHEN PULLING OUT ONTO A MAIN HIGHWAY, THE SAME THING HAPPENED, EXCEPT THIS TIME THE "WRENCH" LIGHT CAME ON, AND THE VEHICLE STARTED LURCHING AND SHAKING EXTREMELY HARD. AGAIN, I GOT TO THE SIDE OF THE ROAD (FORTUNATELY NO VOLUME OF TRAFFIC), PUT VEHICLE IN PARK, TURNED ENGINE OFF, AND RESTARTED - WRENCH LIGHT GONE AND ALL SEEMED OK. TWO DAYS AGO, SAME THING HAPPENED 4 TIMES WITHIN A TWO MILE TRIP, AGAIN FORTUNATELY NO TRAFFIC VOLUME. I HAD THE VEHICLE TOWED TO THE LOCAL DEALERSHIP, AND NO SURPRISE IT WAS THE THROTTLE BODY, WHICH WAS REPLACED AT MY EXPENSE. I SEE THIS PROBLEM IS WIDESPREAD, AND POTENTIALLY VERY DANGEROUS. FORD SHOULD BE REQUIRED TO ISSUE A RECALL BEFORE SOMEONE GETS SERIOUSLY HURT OR KILLED. *TR

3DP15001 · 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
PE13003 · Electronic Throttle Body Malfunction
Opened Feb 21, 2013 · Closed Feb 28, 2014
Status: closed (inferred from source dates) · Engine
On February 21, 2013, the Office of Defects Investigations (ODI) opened Preliminary Evaluation PE13-003 to investigate allegations of electronic throttle body (ETB) failures resulting in sudden reduction of engine power in model year (MY) 2009-2013 Ford Escape, Fusion, Mariner and Milan vehicles. During this investigation, Ford identified a condition in subject vehicles equipped with 2.5L and 3.0L engines that may result in a sudden reduction of engine power.According to Ford, the ETB internal motor contacts may develop a high resistance material buildup condition on the commutator, resulting in intermittent electrical connectivity and reduced engine power. When this condition occurs, the Malfunction Indicator Lamp (MIL) or Wrench light will illuminate and the vehicle may enter a limited limp home mode.Ford?s trade name for the feature is Failure Mode Effects Management (FMEM) mode.In this mode, engine power and vehicle speed are reduced, while full function of the power steering, power braking, lighting, and climate control systems are maintained.ODI?s complaint analysis indicate that the predominant failure mode involved reduced motive power associated with the limited limp home mode with engine speeds limited to approximately 900 RPM. Analysis of warranty claims provided by Ford identified 59,807 claims related to ETB replacements and approximately 50 percent of claims are associated with diagnostic trouble codes (DTC) P2111, Throttle Body Stuck Open, and P2112, Throttle Body Stuck Closed.Ford described several factors where the ETB motor may fail resulting in DTCs P2111 or P2112 but the failure is not an existing stuck open or closed ETB valve position.According to Ford, the ETB control strategy provides the driver with three FMEM modes that allow varying degrees of vehicle mobility depending on the severity of the fault detected.DTCs associated with stuck open or closed throttle valves are designated the highest failure severity resulting in engine speeds limited to high idle corresponding to the limited limp home mode.Vehicles are not likely to unexpectedly stall as a result of this condition, but drivers may characterize the reduced functionality as a stall, even though their vehicle may still has motive capability.Other FMEM limp modes may result in reduced engine performance but will maintain vehicle speed above 20mph. During this investigation, Ford and its suppliers, Delphi and Igarashi, updated the powertrain control module (PCM) software to include a throttle body motor cleaning cycle during key-on and modified the ETB internal motor components design, surface finish and material composition to improve durability. Additionally, Ford developed a remedy procedure and issued a special Customer Satisfaction Program (CSP) 13N03 extending the ETB warranty coverage and instructing dealers to update the powertrain calibration to improve vehicle performance in the event that intermittent electrical connectivity of the throttle body motor contacts occurs. The program extends the coverage for up to 10 years of service or 150,000 miles from the warranty start date of the vehicle, all vehicles are eligible for the program through January 31, 2015 regardless of mileage.Owners of the affected vehicles will be contacted by mail to take their vehicle to a Ford dealer who will reprogram the PCM to the latest calibration. The bulletin was sent to dealers on January 17, 2014 and the owner letter mailing began on January 27, 2014. See the investigative file for copies of Ford's bulletin and owner letter. This preliminary evaluation is closed. The closing of this investigation does not constitute a finding that
DP12006 · Electronic Throttle Body Malfunction
Opened Oct 2, 2012 · Closed Feb 21, 2013
Status: closed (inferred from source dates) · Engine
In a letter dated August 30, 2012, The North Carolina Consumers Council (NCCC) petitioned the National Highway Traffic Safety Administration (NHTSA) to initiate a defect investigation of alleged electronic throttle body failures resulting in engine stall or surge while driving in model year (MY) 2005 through 2012 Ford Escape vehicles. On October 2, 2012 the Office of Defects Investigation (ODI) opened a Defect Petition DP12-006 to evaluate whether to grant or deny the petition. The petition is hereby granted on certain model years. The NCCC letter cites two complaints of stall while driving in MY 2009 Ford Escape vehicles that were diagnosed as failed throttle bodies with diagnostic trouble codes (DTC) P2111, Throttle Body Stuck Open, and P2112, Throttle Body Stuck Closed. The petitioner indicates that the owners of both vehicles reported experiencing repeated incidents of stalling and engine surging. According to Ford, Escape non-hybrid vehicles are equipped with Electronic Throttle Body (ETB) assemblies beginning with MY 2009. Vehicles manufactured between June 22, 2009 and October 15, 2009 may contain contaminated printed circuit boards (PCB) with plating variations. Plating variations could lead to a lack of continuity in the throttle position sensor circuit where P2111 and/or other DTCs would be generated and stored. Ford and its electronic throttle body supplier, Delphi, modified the PCB manufacturing process and issued a technical service bulletin (TSB) 09-23-5. Vehicles produced after October 15, 2009 incorporated ETBs manufactured with a PCB process that resolved this condition. ODI's analysis identified a total of 123 unique reports indicating allegations of reduced motive power or vehicle stall. Depending on the condition of throttle control system malfunction, a driver may experience varying levels of reduced engine performance associated with three limp home modes. In two limp modes, reduced engine performance may maintain vehicle speeds above 20mph while the third is a limited limp home mode with engine speeds limited to approximately 900 RPM. Allegations of stall appear to be related to the limited limp home mode. Vehicles are not likely to unexpectedly stall as a result of this condition, but drivers may characterize the reduced functionality as a stall, even though their vehicle may still has motive capability. Allegations of vehicle surge appear to be related to limp home mode operation. Complaints alleging surge are most likely related to engine RPM fluctuations at low vehicle speeds or idle as the control system engages to prevent engine stall. In limited limp mode, rough-idle conditions may exist while the control system attempts to modulate engine RPMs once the vehicle reaches a reduced speed to maintain approximately 900 RPM. Separately, ODI received 59 complaints alleging incidents of engine stall while driving in model year (MY) 2010-2011 Ford Fusion vehicles. Approximately 60 percent (36) of the incidents occurred at speeds of 40 miles per hour or more. Eighty percent of complaints (47) were received beginning March 2012 and 14 complaints reported that the throttle body was replaced or DTCs associated with limp home modes. Additionally, Ford issued TSB 10-21-6 addressing DTCs associated with idle speed drops and limited limp home mode. The petition is granted on certain model years.Preliminary Evaluation PE13-003 has been opened to assess the scope, frequency and potential safety consequences associated with the alleged defect.See full copy of the closing resume for this defect petition for list of the VOQs associated with the defect petition analysis.
