I have been made aware of failures in the power seat riser assembly in 95-96 Chevy Tahoe, causing the seat assembly to first become loose, and eventually fail. The outcome of the failure results in the driver faling backwards due to the fact that the seat is no longer intact with the rest of the assembly. The first indication of a problem is a "rocking" type movement in the seat mechanism when under acceleration/deceleration, which becomes obvious over a period of time. My truck was taken to the dealer for this complaint while it was under warranty, and of course they could not find the problem. It has since gotten progressively worse. From my understanding the cost for a consumer to replace the defective component to prevent a failure is in excess of $300. I am not aware of any crashes as a result of the seat failure, but there have been some close calls. From my understanding most of the failures occurred when the vehicle driver was seated and making a movement while the vehicle was not in motion.
