On the freeway and car suddenly has overdrive light blinking, at the same time I began losing power, I was able to get off freeway but not after I open hood and nearly got run over. I was checking to see if there was overheating or smoke. But nothing. I have already replaced pcm, transmission, and torque converter. Consequently my shifter is broken and you can see down into transmission. Obviously no I can't drive, I will have to have vehicle towed. Why hasn't transmission been recalled on this vehicle. I could not think about if my child would have been with me and stood in front of car. He never would have been able to move that quickly or even worse with freeway driving I even could have been hit from behind.
Car accelerated as I tried to stop. Then when I tried to go, I pressed the gas and it would not go but the rpm's went really high. Then the car died and I had to wait a few minutes to turn it back on. 2nd incident- I was driving on a busy road during rush hour and tried to stop at a stop light but the car accelerated so I had to keep breaking but the car would not stop accelerating so I turned the car off. When I tried to turn the car back on, nothing worked (had no power at all therefor I could not turn on my hazards to signal to people that my car was stalled). I waited then tried to turn it on again and it turned on but was still accelerating only I was in park so it did not go anywhere. I turned the engine off but did not turn the car off so I could turn hazards on. I waited several minutes then tried again and was able to pull off the road.
The problem is with the gas pedal, its hard to press/accelerate and sometimes when I press/accelerate from a stop and at speeds of 30 mph, it gets stuck and I have to put it in neutral. Very dangerous situation.
The contact owns a 2005 Mercury Mariner. While the contact was driving 55 mph the vehicle had suddenly began to surge forward causing the contact to apply the brakes in order to stop the vehicle from accelerating. The vehicle was taken to the dealership where the contact had the transmission torque converter and throttle sensor replaced. The contact noticed prior that the rear end of the vehicle would jerk whenever it was driven up an incline. The current and failure mileages were 61000.
