GM certified warranty?

[ryanh2]

I purchased my 05 H2 June 7, 07. It was sold as a GM certified6 year 100k mile warranty. The dealer I purchased it from told me everything was covered. That dealer has since closed. I have an appointment to drop it off at another dealer for the following problems. 1) Steering box is leaking bad. 2) Antifreeze leak from somewhere, leaves a small puddle. 3) cigarett lighter and all powerpoints dont work. 4) Powerfold mirrors dont work. Also my tube steps have what I would consider major rust. The dealer I got it from said they were covered. My question is do you think they are going to fight me on any of these issues. The truck has 35k miles.
