I just purchased a 'new' 2008 2500HD LTZ, Z71 4x4, w/6.6L Diesel. I did say 'new,' it was a hold-over from last year, never demo'd or titled - 23 miles original...probably from test drives. I bought it 5 days ago. My state has a NO buyers remorse return policy, you bought it - it's yours! I never bothered to 'inspect' the undercarriage and drive train, it's NEW right? Well, all the shafts, mounts, sway bars, steering linkage, tie rods, brake calipers/backing plates, bushing mounts, and much more are solid RUST! Even along the frame and where there are galvanized parts, etc., they are rusty!? GM Customer Satisfaction seems to agree that that truck SHOULD NOT have that corrosion! The dealer, the service manager, and the salesman say it's "normal." The view under my truck looks like a combination of a NEW p-up and a '68 p-up pulled out of a bayou! BTW, I am a Florida boy, the truck was purchased in NW Florida -- I hate to see how it will deteriorate if it ever sees northern roads in the winter... Comments PLEASE! Thanks!!
