Actually, nobody denied your individual problem, again some of us are trying to understand what defines it and how common it is. Some of us may have science backgrounds where challenging assertions, particularly in light of inconsistencies, is standard. One poster said no vibration is acceptable which is different than what you describe. My car's characteristics are in line with past models -- right now with 1,500 miles. I'd like to understand more about it in case at some point I'm affected. And if I am, I'd like to be able to discuss the problem with engineer types in their language.
If my car did what you're describing I'd be just as dissatisfied.
