I'm very suspicious of Mike's comment. When I called a second dealership to discuss the vibration in my steering wheel he said he was happy to take a look but I "probably wasn't going to like what he was going to tell me". Just like the previous dealer he went on to say all/most of the trucks on their lot have similar problems. Maybe the northeast/NY got a bad batch of trucks? I wanted to enjoy this truck. Beautiful interior, nice looks, but every time I reach 50-60 mph I'm reminded of how poor the vehicle drives......which was never the case with my 2008 or 2003 Silverado. If it was the tires wouldn't the vibration change a little after the rebalance? Wouldn't the frequency or speed at which the vibration occurs change slightly just due to the different weighting and new placement of the bad tire? Vibration was exactly the same in every way after the rebalance. If GM had any confidence in its product they'd be all over this, assisting their loyal customers. Instead they just make sure you have the names of other dealerships in the area, which is useless.
