Dt: 2005 mercury mariner. Consumer's vehicle was involved in an accident on august 5, 2005. The vehicle was driven off the road and went into a ditch. Then, the vehicle went airborne and landed in another ditch. The consumer did not remember what exactly happened, but the police department verified the accident. Upon impact, the driver's seat collapsed.
The vehicle was in a head on collision with another vehicle, both traveling 30MPH. The vehicle was totaled. The driver was wearing their seat belt, and their nose was broken due to collision with the steering wheel. The airbag never deployed.
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.
While stopped, the accelerator pedal sticks in the "up" position, and requires excessive force to move the vehicle. This sometimes results in excessive acceleration when the pedal becomes unstuck.
