I was driving in town going about 40 MPH when the car lost all power, then engine failsafe mode displayed on the information center and a little wrench was also displayed. With no power steering, I had to pull over quickly in lunchtime traffic. After stopping the car, I waited a few seconds and restarted it. No problems with it until the next day when the check engine light came on. I have also noticed a mechanical smell coming from the AC. It appeared, at first, that this problem had come out of nowhere when I suddenly remembered two occasions when the rpms suddenly stuck on 3000 and would not stop until I put the car in neutral. Also, when using cruise control, the whole car shakes and stutters slightly when going up or down very slight inclines.

I have an ongoing issue with the transmission de-engaging when the temperature of the transmission warms up. When I accelerate when passing or using the cruise control the transmission will dis-engage leaving me with no forward power, I must put the car in neutral and hope it engages all the while almost being run over by two semi-trucks. This happened almost a dozen times down and back on my trip from buffalo to peapack nj on monday 4/16/2012. This is a know problem that ford is aware on the five hundred model, montego and some fusion models. Many start to fail at less than 30,000 miles and happened at 65,000 miles on my vehicle. I consider this an extremely dangerous situation and amazed no one has been killed due to these defective transmissions. The ford forum has over 10 pages of complaints regarding this problem. Ford told me they would not do anything unless there was a recall.

After starting car in garage and idling for about 30 seconds, I put car in reverse to back out of garage. The engine RPM's increased significantly, and the car shot backwards until I applied the brake. The car stopped and engine RPM returned to normal. This has happened several times. I am the second owner of the car, and I purchased the car from a private party with about 104,000 miles on it. In speaking with the previous owner, he also had problems that he attributed to the cruise control whereby the vehicle sped up without pressing on the gas pedal. The original owner purchased the car from gentry ford in ontario, or, and had every service performed there. I, too, have returned the car to gentry ford for every service, but have not discussed this problem with them, the previous owner did tell them about the problem he experienced.

Not long after purchasing my vehicle my husband and I were driving on the interstate with the cruise control on and the transmission stopped working. We were able to pull off safely onto the shoulder and shut the car off and once restarted was fine. We have since stopped using cruise control in fear of an accident. The problem is still there and seems to be getting worse. The dash will light check transmission, traction control and sometimes check engine. Once the car is turned off and back on it is fine for a while, the check engine light takes some time to go off. It is getting so we are afraid to drive it, sometimes it drives fine and others the transmission quits. The other day I went to pass a car and the lights came on as I had moved into the lane to pass on the interstate. Once I was in my lane again a few minutes later it does it again and this time a big mac truck is coming up on me. I have read of several problems of this with this same car and it has been said there is a problem with the throttle body and/or electrical system. This is very dangerous and ford should be issuing a recall to fix the problem before someone is injured or killed.

The instrument cluster checks normal on most start-ups, but unpredictably all systems light up showing failure of ABS, air bags, traction control, electrical systems, see a mechanic, cruise control and speedometer quits working. The warning lights may stay lit for 2 to 200 miles. And no speedometer. Auto zone and my mechanic are baffled and frustrated after checking battery charging circuit connections and grounds. Its obviously not safe driving without knowing your speed or if there is a major hazard looming-----like fire.
