Mid/rear Seats Assembly problems of the 1999 Honda Accord

Left metal control arm that raises and lowers the drivers seat has broken. Both the metal and the weld have broken and the bar under the seat is no longer attached to the control arm under the left front of the seat. The seat flops and is unstable. This car has not been involved in an accident but the fear is that had it been or should it be, the seat will fall backwards causing serious injury to both the driver and rear seat passenger. Should the right side fail, the seat will not be held in place at all. This does not seem to be the type of failure that should occur under normal circumstances or even in an accident. Honda will accept no responsibility for this failure even though it appears to be a serious safety concern.
