My company has 3 at4's and an slt and they all do this. I got the same run around from dealer, "couldn't duplicate it, here is a bulletin saying it's normal". Pretty disappointing.
Mbcorry - I'm in the same boat, did you manage to find a trailboss with bench and leather? I couldn't. ended up ordering an at4 and plan on swapping the console out with a "booster" from an sle.
