Mid/rear Seats Assembly problems of the 2006 Dodge Ram 2500

The driver's seat breaks and tilts over backwards. The casing/gear box that connects to the motor and moves the driver?s side automatic seat forward/backwards and up/down shatters and the seat falls over backwards during normal acceleration. This has happened twice, once at 30k traveling 65mph and the second at 45k 10-30mph both times nearly causing an accident each time. The first seat was replaced under warranty the second seat broke in the same place less than a year later. The seat is still in my truck broken and I have the seat blocked from falling over backwards with a brick. Both times it broke I was accelerating in traffic, once at a stop light and the other merging onto the freeway. Both times I narrowly avoided hitting the cars around me. Each time, I was tipped backwards into the rear seat space with the drivers seat almost hitting the seat behind me if someone was sitting in the rear seat it could have caused injury. Both times, my hands left the steering wheel and my feet left the pedals, I had to scramble to sit up and correct the vehicle. I have tried to contact both the dealer and manufacturer and they continue to give me the ?run around? stating that I need to pay for a diagnosis before they can make a determination about replacing it. I have three children who sit in booster seats in the back seat; if they were with me it would have broken the legs of the child behind me. It is very alarming, distracting, and dangerous to have the seat tilt to a 45 while driving.
