| PE11018 | Ford Motor Company | 05/11/2011 | 02/07/2013 | Idle instability | ||
| On november 29, 2012, ford motor company (ford) initiated customer satisfaction program 12n03 to extend warranty coverage terms for repair of engine idle rpm surge caused by throttle body deposits in all model year (my) 2005 through 2007 ford freestyle, five hundred and mercury montego vehicles.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 may 31, 2013, regardless of mileage).dealers will repair vehicles exhibiting the condition by removing and cleaning the throttle body and reprogramming the pcm with software containing an updated idle speed control strategy.according to ford, some of the affected vehicles may experience momentary, intermittent engine idle rpm surge (idle flare) when stopped or during low speed driving maneuvers such as in a parking lot or driveway.unstable idle speed control (dips and flares) around the target engine speed (700 rpm) can occur in vehicles with deposit build-up in the throttle body when the system adjusts engine speed in response to changes in engine load, typically from power steering application or air-conditioner compressor cycling.idle speed control logic is only active at vehicle speeds below 3.5 mph and when the accelerator pedal is not applied.ford testing of a vehicle with a worst case throttle body measured a maximum idle flare of 1360 rpm lasting approximately 1 second, which ford indicated was consistent with system design to limit vehicle speed and acceleration in idle control mode.ford indicated that the test vehicle was held in place with normal brake effort and that vehicle speed remained under 4 mph without the brake pedal applied.in addition to throttle body deposit accumulation, symptoms associated with the condition may include check engine lamp illumination and diagnostic trouble codes (dtcs) p0505, p0506 or p061b.ford attributed the surge condition to changes in idle air flow resulting from the progressive buildup of deposits in the throttle body from normal positive crankcase ventilation (pcv) system operation.this condition was not adequately compensated for in the original powertrain control module (pcm) calibration.ford issued a technical service bulletin on august 15, 2011 (tsb 11-8-5), releasing an updated powertrain control calibration for vehicles with cvt transmissions.on october 19, 2011, ford issued a second bulletin (tsb 11-10-21) superseding tsb 11-8-5 and including updated powertrain control calibration for vehicles with 6-speed transmissions.prior to ford issuing the tsb | ||||||

| Tl* the contact owns a 2006 mercury montego. while driving approximately 10 mph, the contact depressed the brake pedal upon approaching a traffic stop signal. the vehicle suddenly lunged forward without warning. the failure recurred whenever the brake pedal was engaged during a complete stop. the failure became progressively worse. the vehicle had not been diagnosed or repaired. the manufacturer was not notified of the problem. the approximate failure mileage was 80,000. the vin was unavailable. | |||

| I turned on road heading south and increased speed to limit of 55 mph and set cruise control. the road sloped slightly downward and the car was not requiring gas. the sensor got confused and the engine cut out leaving me suddenly without power. i was able to pull over off the road put the car in park and restart it i di not have a recurrence but am very concerned about safety. i took car into a dealer and they reset the software but told me it happens to all car manufacturer on a rare occasion and could not guarantee that it would not happen again. if i was not in the right hand lane i could have difficulty.*tr | |||

| Dt*: the contact stated while driving 25 mph the vehicle became stuck at 3500 rpm's. the contact believes it was caused by the accelerator pedal sticking. the engine had to be turned off before the vehicle would stop. three attempts were made at restarting the vehicle before it would idle normally. the vehicle was taken to the dealer both times and the problem could not be duplicated. updated 08/25/06. *jb | |||
