The exhaust manifolds on my truck are severely rusted and bolts have broken off causing the dreaded po430 code and now the truck won't pass state emissions testing until I spend over $1,000 correcting general motors' defect. So many trucks were effected and my cousin's 2005 tahoe had the same exact issue. Both trucks are well maintained and mine is normally parked in my garage and cleaned frequently. Don't let me get started on the rust under the rear doors. Great trucks but gm really dropped the ball with quality of these parts. It's unfair to the customer to have to correct these issues despite taking good care of their vehicles. I own 5 vehicles and none of them have this issue, even my 22 year old 96 impala ss.
