general problems of the 2004 Lincoln Navigator

The vehicle engaged in involuntary acceleration (in reverse) from stationary position right after shifting gears from parking �p� to reverse �r� and disengaging the parking brake. The brakes were being applied during this gear change. The car started moving in reverse as soon as the driver let off the brakes. The driver then reapplied the brakes but the vehicle accelerated instead of breaking. More pressure was applied to the brakes but that increased the speed instead of reducing it. The vehicle accelerated from 0 mph to approximately 50 mph and traveled about 100 feet in reverse. The driver was maneuvering the vehicle with the steering wheel while simultaneously applying pressure to the breaks. The driver managed to steer the vehicle up a small grassy hill of about 15 degrees in slope until the vehicle hit a residential concrete wall with the back of the vehicle. At the moment of impact, the vehicle bounced back and the acceleration disappeared with the engine still on. The vehicle then slowly rolled down the hill until it hit a parked car. At that moment, the car stopped and remained stationary. The engine was then turned off. The impact caused damage to the back of the vehicle and to the residential concrete wall. The driver's seat was also damaged. It became loose with the impact and was ejected backwards towards the back seat with the driver still on it. There were no physical injuries to the occupants other than whiplash. A firmware defect of the electronic throttle system is suspected.

For the past 6-8 months my vehicle has sporadically stalled/stopped for no apparent reason. When it stops like this it can occur on the highway or surface streets without notice. I have taken it to the Lincoln dealer two times with the last time being told it was a transmission problem, which I was skeptical, because of no previous problems. I have requested assistance from Ford motor who essentially dismissed without any liability due to the car being out of warranty. I am requesting your assistance before there is any injury, accident or fatality. I have the e-mail correspondence with Ford.

The running board intermittently failed to come out properly when either door was used. The consumer took the vehicle to the dealer on 5 separate occasions and was unable to locate the problem. Please provide any further information.
