WHEN I STARTED ACCELERATING IT WOULD STUDDER WHEN RPMS WENT UP AND THEN BASICALLY WOULDN'T LET ME GO OVER 50. I TOOK IT INTO CAR REPAIR SHOP AND THEY SAID MY THROTTLE BODY NEEDED TO BE REPLACED. I LOOKED ONLINE AND SAW THIS WAS A RECENT RECALL. HAVE I MISSED OUT ON THIS OR WHAT? I NEED SOME ANSWERS PLEASE! *TR

I FOUND A 2007 USED TRANNY FROM A REPUTABLE USED DEALER , WE PLACE THE TRANNY IN AT A COST OF 700, THE TRANNY ITSELF 475, UPON GETTING CAR BACK THE TRANNY IS DOING IT ALL OVER AGAIN, I AM NOW TAKING IT TO A DEALERSHIP TO HAVE IT SYNCHRONIZED WITH COMPUTER PROGRAMING TO SEE IF THIS FIXES PROBLEM , I AM NOT HAPPY WITH THE RECALLS ON THIS CAR BUT IF FORD REFUNDS ME AND FIXES I WOULD BE SATISFIED WE LOVE FORD TRUCK AND THEIR PRODUCTS AND FEEL FORD DOES TAKE CARE OF THEIR CUSTOMERS. *TR

I AM ALSO IN THE GROUP OF BAMBOOZLED PEOPLE THAT HAVE THE UNFORTUNATE EXPERIENCE OF OWNING A 2006 MERCURY MONTEGO. RECENTLY ON A 90 MILE TRIP ABOUT 40 MILES IN DRIVING APPROXIMATELY 65 GOING UP A HILL I ACCELERATED TO PASS A VEHICLE AND MY CAR SUDDENLY AND UNEXPECTEDLY JERKED AND LOST SPEED DOWN TO A ABOUT 45 AND WOULD NOT ACCELERATE. THE CARS BEHIND ME HAD TO SLOW DOWN ABRUPTLY AND WERE NONE TO HAPPY AT MY INCONVENIENCE. SINCE THEN I HAVE HAD THE SAME ISSUE REPEATEDLY EACH TIME GETTING WORSE. I CAN NOW FEEL THE TRANSMISSION GETTING WEEK WHEN I DRIVE ON THE HIGHWAY AND ITS ONLY A MATTER TIME BEFORE IT GOES OUT. THIS IS A MAJOR SAFETY ISSUE AS THE YOU ARE NOT AWARE OF WHEN THIS WILL HAPPEN AND THE VEHICLE IS DIFFICULT TO CONTROL WHEN JERKING ABRUPTLY. FORD NEEDS TO DO SOMETHING. MY CAR DOES HAVE 116000 MILES ON IT AND I KNOW CARS ARE NOT MEANT TO LAST FOREVER BUT THIS IS RIDICULOUS THERE IS NO REASON A PROPERLY MAINTAINED TRANSMISSION. SHOULD BE HAVING PROBLEMS LIKE THIS. I AM CERTAIN THIS IS A MANUFACTURER DEFECT. I WENT AGAINST MY BETTER JUDGMENT AND BOUGHT A FORD BECAUSE I THOUGHT THE MONTEGO WAS A NICE CAR. I SHOULD HAVE STUCK WITH MY 97 FIREBIRD THAT HAD 167000 MILES ON IT, LOST WAY LESS OIL, AND RAN WAY SMOOTHER ON IT'S ORIGINAL DRIVETRAIN AND GOT 10 MPG BETTER THAN THIS CAR. NEVER AGAIN FORD! YOU SHOULD STAND BEHIND YOUR PRODUCTS. *TR

PE11018 · Idle Instability

Opened May 11, 2011 · Closed Feb 7, 2013

Status: closed (inferred from source dates) · Vehicle Speed Control

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?s, owner?s experiencing the alleged defect either received no repairs, if dealers could not duplicate the condition, or had the throttle body cleaned or replaced, which only provided temporary correction until the throttle deposit build-up returned.Ford?s revised powertrain calibrations appear to be effective remedies for the idle instability caused by build-up of throttle body deposits.However, even after the TSB?s were released, many owners experiencing the condition continued to have difficulty with proper diagnosis and repair as dealers were often either unable to duplicate the condition or were unfamiliar with the new repair procedures.Ford's new program addresses those concerns.NHTSA's testing and complaint analysis indicate that the idle speed control issue in the subject vehicles can only occur at very low speeds, are very brief events, are easily controlled by moderate brake pedal forces and result in minor increases in vehicle speed even with no braking.This investigation is closed.The closing of this in
