Pete,
I don't see why you're upset. This is how warranties work. I have the same issues with my VX, the only difference being that I bought it ONE month out of warranty, and with only 25,000 miles on it. I didn't even bother calling Isuzu about the warranty issues, though. I asked when I bought it if it was under warranty, and they told me that the bumper-to-bumper had expired. At that point, I knew that little things like this wouldn't be covered. That's just the way it works, man. I bought new wheels and fixed my window myself. Oh well. I guess that's why you pay more for a car still under warranty.
Steve
PS - How can you say Isuzu's warranty sucks when you don't have one?
