I don't have the truck anymore since GM did the Trade in assistance with me but this pictures are from 2 weeks ago, one picture is the driver side and the other is the passenger side. The truck was rust proof numerous times over the 10 months I had it,
After so many months of problems and the rust problem as well GM approved me for a trade in assistance thru the Dealer that was helping me out (this is not the dealer I bough it) I end up getting a Sierra 2500 HD 2015 brand new and Made is the US, not Mexico. I hope I will not have rust problem, heated seat, radio, paint flaking off... This one looks is build right.
That is 5 attempts to cover the rust and making it worse every time, I have rustproof over spray from running boards, to paint, tailgate, back chrome bumper, wheels, exhaust tip etc... and is falling off really bad.
I have the exact same problem, been at the dealer 4 times for that, they said is fix and is not. I have another appointment, after they fix my other issues in a couple of weeks.
Happy New Year, I had the GM "fix" and the dealer rust proof a few months back, I have black "stuff" every where including paint and chrome running boards, I just looked last week and is rusting everywhere again, the same as before. Dealer told me I can go back, but I am tired of having a brand new truck at the dealer for repairs constantly. I didn't have heated seats on 2014, maybe for this year I will.
I had to leave on Saturday after 15 minutes of waiting for the general manager. I did had a meeting with him this morning and GM by email. Dealer said he just followed GM directions.
Thanks GM for fixing it, 3 days at the dealer for the frame issue and Radio sound problem, the radio still not working after update and xm radio antenna replaced.
