1996 GMC Jimmy suspension problems

I was on the highway going at the speed of 45MPH when the ball joint on the front passanger tire broke, causing me to go through 3 lanes without warning and almost flipping my car over. This is not the first time where I have almost lost my life due to manufacturer defects. Last year while driving on the highway, the wipers went out on me in the middle of a thunderstorm. The wipers died out on me a total of 6 times in the last 2 years with over 10 visits to dealers for repairs.

My 1996 GMC jimmy has had ball joint problems (upper and lower replaced at 40k, 79k), ABS problems (recalled to change s/w, failed at 80k) and windshield wiper problems (intermittent failures at 80k). All of these problems have had recalls, but when I contact GMC they tell me my vehicle is not included (VIN [xxx]). What I don't understand is if my car is failing with the exact problems mentioned in the recall notice, then the problems seem to be more widespread then GM is willing to admit. *nlm
