general problems of the 2001 Chevrolet Blazer

I have a 2001 chevy Blazer, 4 dr & 4 wheel drive. And after only 28,660 mi. All 4 front & rear rotors rusted out causing the replacement of all front & rear brake pads & rotors to be replaced. For all 4 rotors to rust out at the same time and at such low mileage requires me to complain. It was an accident waiting to happen. I complained to the chevy division with no results. I was told it was normal wear and tear, which I think is rediculous. I owned chevies most of my life and I never had a problem like this. I could see one or two rotors going bad but not 4 at the same time. Especially rusting out.
