That is a great idea. The difficulty, without doing this, is it is tough to know if all the issues are the same thing, or if they are all different. Is it really as bad as some say, or is it worse than some think. When I read that people on the board are upset their truck is 1/4" high on one side I start to wonder if some of these issues are perhaps overblown. Of course everyone here will be super sensitive to it at this point.Didn't read through the entire thread so not sure if this has been suggested yet, but if we're lucky enough, would someone with a non-vibrating GX be willing to meet up with someone with a vibrating GX and drive them back to back? Then maybe take those two vehicles to the dealership to show them the difference? Probably wishful thinking as the number of GXs out in the wild are pretty small at the moment, but thought I'd throw it out there.
