My passenger seat has failed in the lick position in the track adjustment. one day while driving on the highway, we had to come to an abrupt hault from 75 mph, and my passenger seat broke from its locked position, sending me fireard towards my dash then jammed in that position, the problem i found on the seat track , was the slider bearings broke and unlocked the track, and got stuck with the broken parts in the track, of course this happened after the warranty, sure wish they would take care of this, maybe you can help, on getting seat tracks replaced.
