general problems of the 1998 Dodge Durango

Due to to uneven driveway the vehicle stalled, or transmission began to spin and not move, at which the vehicle ignition was shut-off. It was attempted to push the vehicle about 50 feet to a parking place. Another person offers to help, then pushes vehicle 25/50 feet. . . Advises to turn the wheel. The wheel does not want to turn. The vehicle has used a lot of power steering fluid almost daily(has a history of squealing and hard turning at start unless lubricated). So advice to place vehicle in reverse caused the steering wheel to be even harder to turn, if at all. I requested help from the bystander, who at which point comes to the driver side where I was standing outside of the vehicle also. It's unknown if the bystander help turned the ignition on, or if the ignition somehow turned on by itself. The vehicle was occupied by one addition passenger at the time of the crash. The vehicle traveled in reverse gear, without anyone pushing on the accelerator. There were minor to severe injuries, and damage to 2 vehicles and one structure.
