ON 1/1/2016 I WAS DRIVING ON 495 W IN QUEENS, NY HEADING BACK TO MANHATTAN WHERE I LIVE. OUT OF NOWHERE THE CAR BEGAN JERKING, A WRENCH LIGHT ON THE DASH PANEL CAME ON (WHICH I NEVER SAW BEFORE) AND I COULD TELL THE CAR WAS DECELERATING. I TRIED HITTING THE ACCELERATOR AGAIN, THE CAR WOULD JERK, THE ENGINE WAS REVVING BUT WAS BARELY MOVING. I KNEW I HAD TO PULL OVER AND LUCKILY I WAS ABLE TO NAVIGATE TO THE SHOULDER OF THE ROAD. THIS WAS AN EXTREMELY DANGEROUS SITUATION. I AM A CONFIDENT DRIVER, HOWEVER, A LESS CONFIDENT OR TIMID DRIVER MOST LIKELY WOULD HAVE PANICKED AND GOTTEN INTO A POTENTIALLY SERIOUS COLLISION.

WHILE DRIVING DOWN THE ROAD ANYWHERE FROM 20-55 MPH, THE CAR SEEMS TO STALL OUT AND THE ACCELERATOR NO LONGER WORKS. YOU HAVE TO PULL OVER AND SHUT THE VEHICLE OFF AND IT WILL START AGAIN. SOMETIMES THE SAME PROBLEM WILL OCCUR AGAIN WITHIN SECONDS, MINUTES, OR DAYS LATER.

RESTARTED AND RESUMED NORMAL DRIVING. SUSPECT ELECTRONIC THROTTLE BODY. THE FORD DEALERSHIP WILL NOT REPLACE WITHOUT A DIAGNOSTIC FEE BECAUSE THEY STATE IT IS NOT A RECALL, ALTHOUGH AN INTERNAL VEHICLE HEALTH REPORT STATES "THERE ARE RECALLS FOR YOUR 2009 MERCURY MARINER AT THIS TIME" NOTICE # 13N03 ELECTRONIC THROTTLE BODY EXTENDED COVERAGE I BELIEVE USING THE WORD RECALL CONSTITUTES MISREPRESENTATION WHEN IN FACT FORD MOTOR COMPANY STATES IT IS JUST A CUSTOMER SATISFACTION PROGRAM TO ALLEVIATE THEM FROM COSTS AND ANY WRONG DOING. IT IS A VERY DANGEROUS SAFETY CONCERN.

CHECK ENGINE LIGHT CAME ON WHILE DRIVING 55 MPH ON THE FREEWAY ON 8/11/14. NO SIGNS OF MALFUNCTION INITIALLY. LATER THE CHECK ENGINE LIGHT WENT OFF ON 8/13/14. TOOK MARINER TO FIRESTONE AUTO CARE TO DIAGNOSE CHECK ENGINE LIGHT. THEY TOLD ME IT WAS P0022 - VCT SOLENOIDS, BUT THE ENGINE WAS STILL RUNNING FINE. THEY RESET THE COMPUTER AND TOLD ME THE NEXT TIME THE CHECK ENGINE LIGHT COMES ON TO TAKE IT INTO A DEALERSHIP. SO THE CHECK ENGINE LIGHT COMES BACK ON BY 8/17/14. STARTED NOTICING SHUTTERING BETWEEN 50-60 MPH ON 8/22/14. TOOK CAR INTO DEALERSHIP ON 8/27/14. WAS TOLD THAT THE VCT SOLENOIDS NEEDED TO BE REPLACED AT APPROX. $620 AND THIS CAR ONLY HAS 29K MILES ON IT AND OF COURSE IS OUT OF WARRANTY. THERE IS A SERVICE BULLETIN ON REPLACING THE VCT SOLENOIDS BUT OF COURSE NO RECALL HAS BEEN ISSUED. A RECALL SHOULD BE ISSUED AND I SHOULD RECEIVE REIMBURSEMENT FOR THIS REPAIR FOR SOMETHING THAT IS OBVIOUSLY A WIDESPREAD PROBLEM WITH MARINERS AND ESCAPES FROM 2009-2011. *TR

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
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
