NHTSA Complaint #11493065 — 2010 CHRYSLER SEBRING

The driver seat has a part that wears out and causes the power seat to move forward and backward on its slide track. eventually the part will fail and the seat will slide right into the steering wheel which will impact the drivers chest. The power seat has two acme threaded rods that drive the seat rails forward/ backwards to allow driver to adjust the seat. the acme rods drive a custom screw block to allow the motion. when in static position only the screw block holds the seat and stops it from moving forward and backward. from what i can observe the acme rod is case hardened but the screw block is not. the screw block seems to wear out prematurely after four years. if left unaddressed the screw block could fail completely and allow the seat and passenger to hit the steering wheel while braking or in a front end collisdion.
