Mid/rear Seats Assembly problems of the 1999 Chevrolet Silverado

Plastic seat-locking device on driver side seat broke in half inside rail causing the seat to slide back and forth without any restriction thereby preventing the seat from locking into position. Had noticed several times that the chair had difficulty lokcing when seat was adjusted to gain access to back seat.

The driver's seat track is broken. It is very difficult after accessing the rear seat to get it to lock in place. Somtimes slides forward or backward without warning. Seat tilt adjuster also broken, just flops on floor. Dealers are not very helpful. Huge safetly issue.

The drivers side seat "adjuster" that retains the front seat position when the rear seat has been accessed, failed, resulting in the inability of the drivers seat to remain in a fixed position. This condition allows the drivers seat to slide back and forth depending on accelerating or braking. The part is a white plastic (most likely polypropylene based), and is not of sufficient strength for it's job. Plastics tend to get brittle with age and this may be part of the problem. Even though this failure occurred while I was stationary, accessing the rear seat area, when I did attempt to park the vehicle in my driveway, knowing full well the seat was not secure, the very slightest touch on the brake pedal sent me flying forward and I banged my knee on the dashboard! this is most definitely a "safety issue" as there are 16 complaints already on the NHTSA web site for 1999 sliverado's with this same problem! I have contacted Chevrolet's customer service department and they advised me to take my truck to the dealer. I told them it is unsafe to drive and would they pay for a tow? they told me I am responsible to get the vehicle to the dealer for "inspection" and then they will evaluate the problem. I said, "there is no more evaluation needed than the fact the part broke and it is unsafe" this is a safety defect and I have seen recalls issued for less serious issues. I feel NHTSA should look into this problem and mandate a recall on this problem. Some owners have had this happen more than once! will NHTSA wait until someone is seriously hurt or killed before they act?.

A little plastic latch that is suppose to reposition the drivers seat in the same place after access to the back seat broke. With out it there was no way to lock the seat in place so it just slid back and forth freely.
