I had to call isuzu ameria and get them to change the name screen on my truck so I was reflected as the new owner (ie: warranty covered owner). They said the warranty was 5 years 60,000 miles for the powertrain and 3 years 50,000 miles (i believe) on the bumper to bumper. I think it was 50,000 miles but you'd have to call them to make sure.

I've had the window binding fixed (replaced a regulator or somthing), headlight striping (somwhat fixed, I ended up redoing it myself cause they f***ed it up) and all 4 rims completely replaced under warranty. The dealer really had no questions or problems doing any of this work, it didn't cost me a dime, it just took awhile for the rims to come in.

You'd actually be amazed at how bright and shinny the rims look when they are chromed on the inner back portion compared to dark and chipping

Hope this helps,
