| The car was purchased in may of 2011. august 2011, the transmission started to violently jerk and act as if it were in neutral. when gradually applying the breaks, the car would begin to shudder. this would happen only if the engine was warm. by march 2012, the shuddering transmission and jerk was constant. i took it in to be looked at in april of 2012. the alternator was replaced, due to what we thought was a bad battery. the mechanic believed this caused the transmission to jerk. the problem was not solved. june 2012 the transmission was replaced by a ford dealership for 5,000. july 2012 the car went into fail engine safe mode, the codes pointing to the throttle body. a mechanic cleaned the throttle body saying it might solve the problem. 2 days later the car went into fail engine safe mode again with the same codes with an estimate of $900. the car has 72000k on it and has had three major problems in the past couple of months. *tr | |||

| The instrument gauge on my 2005 mercury montego just went dead. nothing registered, so there was no reading on my speed, engine heat gauge, fuel level, or tachometer. this happened once in early spring of this year (2012), but did not repeat until recently. it is now june and the same thing has re-occurred about 10 times in the past two weeks. after turning the car off and restarting, this sometimes (but not always), fixes the problem. most recently, if the gauges do work, the check engine light turns on. the airbag light stays on, and the awd malfunction message displays in the information panel until i hit the reset button. from a safety perspective, is this a short in the system or is my airbag really malfunctioning? and how do i know my speed other than to guess? | |||

| Engine revs up, and car lurches, typically when: - shifting into drive or reverse and/or moving away from idle; - almost always when the wheels are cranked all the way to the left or right and the car is moving away from idle. the lurching is sudden and violent enough that it can catch a driver unprepared - my wife and i are used to it and able to compensate, but we aren't letting our 17 year-old drive the car for now unless one of us is with her. ongoing problem since car was purchased new. this has been an occasional problem for years - complaint was even made while car was still under its 3 year/36,000 mile warranty (nothing found). problem has been getting more frequent over the past year or so. | |||

| My 2005 mercury montego has an instrument failure in which all warning lights stayed on. one light remained on after ignition was off. the backup lights stayed on while in drive presenting a significant safety hazard. for example, a car approaching from the rear, upon seeing faulty backup lights on may swerve to avoid. this situation would be even more likely to happen at night on a two lane road. nhtsa previously closed the original investigation due to | |||

| Tl* the contact owns a 2005 mercury montego. while driving 35 mph the temperature gauge went from normal to zero and then back up to normal. the vehicle was taken to the dealer and the wire that caused the temperature gauge to malfunction was replaced. the failure could cause high voltage in the electrical circuit, which could have lead to a fire. the current mileage was 57,080. the failure mileage was 54,956. updated 11/13/09.*lj the consumer also stated the engine light illuminated as well. the mechanic found three codes stored for the engine coolant temperature circuit. they indicated an intermittent high voltage in the ect circuit. the freeze frame date showed 40 degrees indicating the circuit was open at some point. extensive testing was done of the coolant sensor and related wiring and it was finally discovered that a bad spot in the sensor orange wire inside the harness at the back of the motor where it takes a sharp bend. the harness was pulled apart and the faulty section wire was repaired. updated 11/17/09.*jb the consumer wants to know the result of his complaint. updated 01/21/10.*jb | |||
