Latches/locks/linkages: doors: latch
- What is wrong
- On certain passenger vehicles currently registered in the following states: alaska, colorado, connecticut, delaware, idaho, illinois, indiana, iowa, kansas, kentucky, maine, maryland, massachusetts, michigan, minnesota, missouri, montana, nebraska, new hampshire, new jersey, new york, north dakota, ohio, pennsylvania, rhode island, south dakota, utah, vermont, west virginia, wisconsin, and wyoming. The side door latch mechanisms may experience water intrusion allowing the latch mechanism to freeze in cold weather.
- Risk
- As a result, the door latch pawl may not return to the latch position when the door is closed, and the door could open while the vehicle is moving.
- Remedy
- Dealers will install a shield over the front latches; seal a drain hole in the rear window trim molding on the freestyle rear side doors; and apply grease to all front and rear side-door latch mechanisms free of charge. The recall began on november 8, 2006. Owners may contact ford at 1‑800‑392‑3673.

Fuel system, gasoline: storage: tank assembly: mounting
- What is wrong
- On certain passenger vehicles, the straps that secure the fuel tank to the vehicle body may break, causing the fuel tank and fuel tank heat shield to drop on the driveshaft (all wheel drive vehicles) or exhaust system (front wheel drive vehicles).
- Risk
- If this happens, drivers may notice a noise or a fuel leak. A fuel leak in the presence of an ignition source could result in a fire.
- Remedy
- Dealers will replace both fuel tank straps. The recall began on december 1, 2005. Owners may contact ford at 1‑800‑392‑3673.

Defect investigations
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?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.the federal safety agency'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

What 2005 Mercury Montego owners say
Most recent owner complaints, unedited.
Tl* the contact owns a 2005 mercury montego. The contact stated that when the vehicle was started, the front passenger's side door remained open which resulted in a loss of the normal functions of instrument panel due to the passenger's side door ajar message overlaying all other system functions on the instrument panel. The vehicle was not taken to the local dealer. The vehicle was not repaired. Upon investigation, the contact associated the failure with the federal safety agency campaign number: 06v383000 (latches/locks/linkages) however, the VIN was not included. The manufacturer was not informed of the failure. The failure mileage was approximately 180,000.
I own a 2005 mercury montego. While driving various speeds, all of the instrument panel gauges would illuminate and drop to zero and the seat belt indicators would illuminate and chime. The vehicle was not diagnosed or repaired. The manufacturer was not notified. The approximate failure mileage was 135,000
When lowering the original car's manual scissor jack it gave out half way down causing the vehicle to drop onto my driveway suddenly. The threading on the power screw seem fine but the pin that it feeds through on the other end looks mangled (see pictures). When the jack dropped it sounded like the power screw slid. No one was harmed.
Engine safe mode
The linkage that controls the gear shift allowed the car to roll while the car was supposed to have been in park. Moreover. The car was in park but wouldn't start. When the tow truck put the car on the flat bed, the car tried to roll off even though the car shift level was in park. The car was in park and the engine was off. And the key wasn't in the ignition.. The car was repaid to the tune of about $800.00. It had to do with some linkage that runs underneath the battery box. Also the car wouldn't start.
I purchased bridgestone ecopia 225 55 r18 and about four months after I've had them had bubble show in front tire took it back to firestone they replaced it after replacing it now it's been a month I have another bubble in the same tire that they just replaced and they are the bridgestone ecopia ep422 tire size 22555 r18
Tl* the contact owns a 2005 mercury montego. When the contact attempted to close the driver's door, the latching mechanism did not engage. The vehicle was not taken to an independent mechanic or dealer for diagnostic testing. The manufacturer was made aware of the failure. The vehicle was not repaired. The approximate failure mileage was 147,500.
Tl* the contact owned a 2005 mercury montego. While driving approximately 30 MPH, the vehicle experienced unintended acceleration and crashed into the rear of a second vehicle. Prior to the failure, the engine rpms erroneously increased and the vehicle surged forward. The front end of the vehicle sustained severe damage, but the air bags did not deploy. The vehicle was destroyed and towed. There were no injuries and a police report was filed. The manufacturer was notified of the failure. The local dealer was not notified. The failure mileage was 150,000.
The car has been lurching forward and decelerating randomly. Keeps going into "failsafe engine mode" and the wrench light comes on but only for a few moments, then runs normally again after restarting. Haven't been able to have the light on long enough to get diagnostics done. Happens while driving or when starting occasionally.
