IMMEDIATE LOSS OF POWER AND COMPLETE LOSS OF ACCELERATION. THIS HAS OCCURRED IN AN INTERSECTION AND IN THE MIDDLE OF A MULTI-LANE HIGHWAY AT 35 MPH AND 60 MPH AND WHEN EITHER ACCELERATING OR HOLDING AT A STEADY SPEED. THE WRENCH LIGHT COMES ON AND THE VEHICLE IMMEDIATELY LOSES POWER AND DECELERATES REGARDLESS OF SPEED. THE VEHICLE IS INOPERABLE UNTIL IT IS TURNED OFF AND RESTARTED. THE PROBLEM IS RECURRING AND UNPREDICTABLE. BECAUSE THE CODE DISAPPEARS UPON RESTARTING IT CANNOT BE DIAGNOSED. I HAD TO GET A CODE READER TO GET THE CODE WHICH HAD TO BE USED AFTER AN EMERGENCY STOP ALONG THE HIGHWAY. THIS IS DANGEROUS AS THERE IS NO WARNING BEFORE THE LOSS OF POWER. ERROR CODE P2111-THROTTLE ACTUATOR CONTROL SYSTEM STUCK OPEN. THE PROBLEM HAS OCCURRED 10/29/15, 11/16/15, 11/25/15, AND 11/30/15.

A RECALL WAS ISSUED ON 05/28/2015 FOR DEFECTIVE AIRBAGS THAT COULD RESULT IN INJURY OR DEATH IF ACTIVATED. THE REPLACEMENT PART IS NOT YET AVAILABLE. I REQUESTED THAT FORD PROVIDE A LOANER CAR AND I WAS ADVISED THAT "AT THIS TIME, IF A LOANER VEHICLE IS AN OPTION, THIS IS SOMETHING THAT YOU WOULD HAVE TO DISCUSS WITH THE DEALERSHIP. FORD IS NOT OFFERING LOANER VEHICLES. THE U.S. GOVERNMENT'S NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION SAYS THAT IT (NHTSA) WILL ORGANIZE AND PRIORITIZE THE REPLACEMENT OF THE DEFECTIVE AIRBAG INFLATORS TO ENSURE THAT DEFECTIVE INFLATORS ARE REPLACED WITH SAFE ONES AS QUICKLY AS POSSIBLE, ADDRESSING THE HIGHEST RISKS FIRST. ACCORDING TO NHTSA ADMINISTRATOR MARK ROSEKIND, YOU ARE ENCOURAGED TO TAKE YOUR VEHICLE TO THE DEALERSHIP FOR REPAIR AS SOON AS YOU ARE NOTIFIED THAT PARTS ARE AVAILABLE, BUT YOU SHOULD CONTINUE TO DRIVE YOUR VEHICLE UNTIL THEN." SO I AM BEING TOLD BY THE NHTSA THAT IT IS OK FOR MY DAUGHTER TO DRIVE HER VEHICLE AND ESSENTIALLY RISK HER LIFE OR SERIOUS INJURY? I WOULD JUST LIKE CONFIRMATION OF THAT SINCE IT HAS BEEN OVER 4 MONTHS AND NO REPLACEMENT PART IS YET AVAILABLE NOR HAVE I BEEN GIVEN A TIME FRAME FOR WHEN IT WILL BE AVAILABLE.

PE11024 · Inability To Shift Gears On Acceleration

Opened Aug 3, 2011 · Closed Dec 14, 2011

Status: closed (inferred from source dates) · Power Train:manual Transmission

The Office of Defects Investigations (ODI) analyzed complaint data provided by Ford as well as complaints submitted to ODI from consumers.In total, there were 364 unique reports indicating various shift quality issues while driving.Ford identified several factors that may contribute to shift quality concerns in the subject vehicles, including cold transmission, clutch stay-out at high engine speeds, gear clash or grinding, and gradual loosening of clutch plate bolts in some early production vehicles.The largest percentage of complaints indicated higher than expected shift efforts in cold ambient temperatures.These complaints were related to transmission fluid viscosity and the higher shift efforts resolved themselves with the drivetrain warming.Ford published technical service bulletin TSB 11-3-18 to inform technicians that a lower viscosity fluid was available for use to address the cold shift issues.The clutch stay-out condition typically occurs at engine speeds greater than 4000 rpm.It does not prevent the selection of any gear, but may delay clutch re-engagement depending on how long the driver maintains the higher engine speed.Ford identified rotating inertia of the clutch components as the root cause and replacement clutch pedal parts were made available under Ford TSB 10-19-4.A number of reports alleged increasing difficulty selecting gears along with gear clash or grinding.Grinding or notchy gear shifts may be caused by gradual loosening of clutch plate fasteners, which is promoted by certain aggressive shifting.This condition is progressive in nature and initially results in symptoms related to shift quality/feel.Clutch plate bolt loosening will not result in inability to select any gear unless the progressive symptoms are ignored until complete clutch failure occurs.ODI?s analysis identified only five complaints alleging an inability to shift into gear due to loose clutch plate bolts.None of these resulted in a stall and gear shifting could occur before engine start.A revised fastener was designed and implemented in production and is available for service through a special service message.There is no indication of loss of motive power or unreasonable safety risk associated with the alleged defect in the subject vehicles.This preliminary evaluation is closed.
