Fuel Injection problems of the 1996 GMC Sonoma

There are numerous, substantial safety hazards to these vehicles which appear to be common knowledge to mechanics but denied by dealerships. The ball joints are apparently common failures according to massachusetts safety inspectors and are deemed to be an extreme safety hazard. They state that dealerships regularly deny any responsibility for this failure. My vehicle is extremely well cared for, not abused in any way, and has experienced defects, which in my opinion demonstrate gross negligence on the part of GMC's engineering/production. I am also a professional engineer, and prepared to testify the same.

While traveling 70 mph, truck lost all power shutting down w/brakes and steering becoming non-functional. Please describe details.
