Front Seat Power Adjust problems of the 1997 Cadillac Deville

Power seat seatback goes down while driving. In December of 1999, dealer replaced memory module to remedy this problem. Since November of 2001 seatback will intermittently go down on it's own. Consumer also states more often then not, when you start the car the seat will move in several different directions. When the back goes flat it pins any passenger in the rear seat. Ph 09-Dec-2002.
