What is this "vibration" that people are feeling? Please describe it in detail. Are you sure, its not just the "roar" of the engine/exhaust pipes? I do not feel any vibrations in my 6MT but do sorta feel the engine/exhaust system roar (which can sorta be classified as a vibration I guess)??. I am still not so sure I do not have the vibration. Weird huh? It sounds normal to me though because it is not bothering me. Is it possible that people are mistaking the vibration complaint and exaggerating the normal engine roar sound? However, the thing that does bother me is that the EL42s suck in the rain and snow. Need to start in 2nd gear in snow and the tires spin with VSA on way too often. Even in the rain, I just do not feel the safe "attached to the road" feel I had with my other cars, which had Michelin MXV4. The EL42s have as if no thread depth compared to the Michelins. I am going to have dealer change them at my first oil change, I already complained to them and they did not say no to switching them (which sounds optimistic to me). I plan to force the issue too because I paid MSRP and waited from July to December to get the car. Oh, they owe me, and when someone owes me, they pay! LOL

Mine is subtle and intermittent depending on how cold it is outside over night, or how long I leave it sit. In general I find it to be a small annoyance that normally goes away within 5 minutes. However, if and when Acura offers to do something about it, I'll have my car in to end the problem so I don't have to think about it ever again.
