VEHICLE SURGES WHEN YOU LET OFF THE BRAKE. THIS STARTED SHORTLY AFTER WE PURCHASED THE CAR A COUPLE YEARS AGO. THEY EITHER SERVICED OR REPLACED THE THROTTLE BODY AND THAT WORKED FOR ABOUT 6 MONTHS OR SO. NOW THE CAR SHAKES REALLY BAD ANYTIME WE HAVE TO STOP AND HAVE TO KEEP FOOT ON THE BRAKE REALLY HARD, SOMETIMES THE CAR DIES DURING THIS TOO AS WELL AS GOING FROM REVERSE TO DRIVE. AS SOON AS YOU LET OFF THE BRAKE THE CAR ACCELERATES, CAN MAKE IT UP TO ALMOST 40 MPH WITHOUT EVEN TOUCHING THE GAS. IT RUNS HORRIBLY IN THE HEAT TOO. ANY TEMP OVER 70 IT JERKS INTO 2 OR 3RD GEAR HARD WHEN STOPPING AND GOING.

PERIODICALLY BUT OCCURING MORE OFTEN. ONCE THE CAR IS PLACED IN DRIVE OR REVERSE BUT FOOT STILL ON THE BRAKE, ONCE THE BRAKE IS RELEASED THE CAR QUICKLY AND AGGRESSIVELY ACCELERATES ON IT'S OWN WITHOUT PRESSING THE GAS PEDAL AND WITH VERY LITTLE REACTION TIME YOU HAVE TO SLAM THE BRAKE PEDAL TO MAKE THE CAR STOP AND THEN THE CAR CUTS OFF. THIS HAS HAPPENED AT LEAST 4 TIMES WITHIN THE LAST MONTH. VERY DANGEROUS! I HAVE RESEARCHED RECALL INFORMATION FOR THIS MODEL AS WELL AS MY DIRECT VIN NUMBER ASSOCIATED WITH MY VEHICLE BUT I HAVE YET TO FIND A RECALL. HOWEVER I HAVE READ MANY REVIEWS OF THE SAME ISSUES WITH OTHER FORD 500 OWNERS.

CAR IN THE MORNINGS IS ACCELERATED AND WHEN PLACED IN REVERSE IT MOVES BY ITSELF VERY ACCELERATED AND ITS PARKED ON A FLAT SURFACE WITH NO SLOPES. TRANSMISSION FEELS AS IF RUNNING FORCEFULLY BUT CHANGES GEARS I GUESS FINE JUST GOT THE CAR AND HAS LOW MILES AT 27000 MILES. AND DOES IT EVERYDAY.

THE VEHICLE HAS UNINTENDED ACCELERATION ISSUES. THERE WAS AN INVESTIGATION BY THE NHSTA BUT NOTHING CAME OF IT. THE CAR STILL ACCELERATES ON ITS OWN WHEN I PULL INTO PARKING SPACES OR LEAVING PARKING SPACES. I HAVE TO KEEP MY FOOT ON OR BY THE BRAKE PEDAL AS TO NOT HIT OTHER CARS OR PEOPLE. HAVING THE AIR CONDITIONING ON SEEMS TO WORSEN THIS PROBLEM SUBSTANTIALLY. IT IS COMPLETELY RANDOM AND I KNOW I'M NOT THE ONLY PERSON THAT HAS EXPERIENCED THIS ISSUE. PLEASE REOPEN YOUR INVESTIGATION AND MAKE SURE YOU HAVE BOTH THE AC ON AND OFF. IT'S MAINLY WHEN IT IS ON, BUT STILL COMPLETELY RANDOM. I DON'T KNOW HOW PEOPLE AND PROPERTY HAVEN'T BEEN INJURED OR DAMAGED AS A DIRECT RESULT OF THIS WELL KNOWN ISSUE.

THE CAR WILL SURGE WHEN YOU PUT IT IN GEAR. DOES IT IN DRIVE AND REVERSE. I HAVE TO KEEP MY FOOT ON THE BRAKE UNTIL I AM AWAY FROM A CAR OR BUILDING AS IT WILL JUMP INTO THEM. I NEVER KNOW WHEN ITS GOING TO DO IT. I ESTIMATED WHEN IT STARTED AND IS STILL DOING IT. *TR

1PE11018 · 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
