Front Seat Head Restraint problems of the 1999 Chevrolet Silverado

Adjusting front driver seat when adjusting lock broke sending seat sliding forward. Seat will not lock just slides back and forth when driving. Since safety belt restraint is in the seat and not bolted to the actually frame of truck seat slides back and forth during braking and acceleration. Not safe to drive until fixed. The broken piece is a three inch piece of plastic. I really don't feel safe now in knowing that the only thing restraining me from crashing into the steering wheel and into a inflating airbag during a front crash is a piece of plastic that could and will at any time break for no apparent reason except for the fact that Chevrolet has a design flaw and still does not feel they should issue a recall to have this replaced with something that would provide more security than a piece of plastic. And the kicker is the tech at the dealer claims it takes 2. 5 hours to replace the locking adjuster at the rate (my bill was $230 just for the labor) and the part cost ranges from $150 to $200 depending on where you get it. Outrageous if you ask me. I called Chevrolet customer service and was able to get my part for free but still had to pay labor to have it installed. I have a 1999 Silverado but it only has 11,000 on it so the part definitely did not break due to wear and tear. So I guess after a few people are seriously injured or killed maybe someone will actually do something about safety issues such as this and make the manufacturers of these vehicles with safety issue responsible.

Seat position mechanism on manual adjust 60/40 bench seat failed causing seat to unexpectably move forward during a panic stop. The seat moved from rear most position to front most position. During this event the seat belt also failed to restrain the driver. No injuries were present.
