The drivers side bottom metal seat bracket broke while in motion. the seat is now completely unsupported. the seat moves when brakes are applied.
The seat started to slide forward upon breaking and slide backwards upon acceleration, this causes extra force to be applied to pedals because i am being slid into the pedals or away from the pedals.
River's seat collapsed and came off tracks while car was being driven. defective welds (as stated by infiniti certified dealer service center) holding seat assembly determined to be cause. infiniti diagnosis; seat track broken. requiring replacement of front adjuster assembly; part # 87450-eh00a. cost of part $~1000 to install; $~300. this is a nissan/infiniti problem reported previously to nhtsa on numerous occasions. dealer service department stats that weld failure causes seat to collapse. problem is longstanding, well documented, and known to infiniti. in spite of this, no remediation, other than repair at owner's expense, has been offered by infiniti. this weld failure is a serious safety related matter that is not the result of abuse, maintenance neglect, or overstress to seat or seat assembly. the has been acknowledged by repair personnel at dealership that carried out the repair.
The driver side front seat mechanism has failed in my vehicle. this vehicle is equipped with six-way power adjustable seats. as i was driving the vehicle, the seat suddenly drop to the lowest position on the floor and will no longer raise or lower. as well, the seat now seats not to be properly anchored to the floor of the car. the right side of the seat belt is attached to the bottom of the seat rail and when i stop or put any tension on the seatbelt, i can feel the seat moving about. i am afraid to allow my son or my wife to drive this vehicle as it seems that the seat will not stay anchored to the floor in the event of an accident. *tr
