Steering Gear Box Shaft Pitman problems of the 2002 GMC Sierra 2500

While driving of a city street, at a slow rate (10-15mph) and taking a slow, approximately 90 degree left turn, I heard a loud "popping/breaking sound". While making the turn, I initially had turning capabilities until I heard the "pop" sound. Upon hearing the sound, I no longer had the ability to turn the wheels to either direction. Upon stopping and turning off the truck, I found the pitman arm(connected to steering box and steering bar) was detached from the steering bar but still attached to steering box. The bolt of the pitman arm had broken off cleanly from the steering bar, rendering my steering capabilities ineffectual. Attached is a picture of the pitman arm sheered bolt. I would like to file a complaint that this defective piece of material could have cost damage to life, property and potentially death of myself or others on the road. I would like some form of restitution on part of the manufacture. The total cost of the repair was approximately $225 usd. I can provide the bill for towing, mechanical repairs and cost of replacement part.
