Its this simple. I bought a beautiful "used" 2007 GMC Yukon Denali. A week later a light came on saying service suspension system. I took it in they couldn't figure it out. I took it to GMC dealership. The Air compressor for my Suspension system is failing $702.00. Well Tim Mills at Tim Dahle Nissan says no they won't Pay. My warranty type is E and its covered under warranty F. So I have bought a broken car from these people and they will pay in all the reviews I write. Which I will write on every page.
