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.

My 2005 Mercury Montego shuts off while going down the road. I have paid around $4000 to try and have the problem fixed and it has never stopped. The reverse gear is unusable, as soon as you put it in reverse it shuts the car off. The transmission jerks and will not steadily accelerate at random times. The car will randomly shut off when going down the road losing all power steering and power braking ability. This is particularly a problem considering I have an infant in the backseat most every trip. I saw this lawsuit and every single thing listed about the cvt transmissions has happened and is still happening to my 2005 Montego.

I was in the meddle lane of a four lane highway when I lost all my acceleration. The motor was still running but I could not go anywhere. When I got off the highway I restarted the car but every few miles it would do the same thing. Am told that it is a bad throttle body and Ford has known about it for years but is not doing anything about it. It is going to get people killed ! my part cost over $600 so it sets in the drive.

On 2/27/13 throttle was cleaned not replaced per Ford recall 12no3. On 5/18/13 being stuck in construction traffic at a stand still, foot on brake engine proceeded like a 747 getting ready to take off. Car moved forward some 1 to 2 ft.. killed engine, turned it on again with foot on brake car proceeded to move. Killed engine, turned back on. No other problem until I was at a stop light on way to destination. Again engine begin to whine at high rate as if I was in neutral and had foot a gas. Killed engine and was able to proceed to destination without problem. Took vehicle to Ford dealership on 5/9/13. Dealership did diagnostic, found throttle body bad. Had to be replaced. There was on or about 3500 miles on vehicle since time of cleaning to repair. Of the 3500 miles, 2000 was on our trip. Talked with Ford corporate stated dealership problem not theirs. Ford is aware of this problem and has chosen to clean rather then replace. It is my understanding that this throttle control ties into the transmission in which Ford has had their share of problems.

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.
