Hi all, First time posting a question in this forum, so far I have benefited a lot by just reading it :). So, I received the same 22N12- Flex Plate Crack on 2.0 notice. When I called the dealership to schedule the service appointment I was told they will charge $320 if the flex plate is not cracked. This can't be legal. I hear the rattling noise when I start the car sometimes and occasionally the car will shake more than usual, but there is no way to tell for sure the problem is the flex plate. Anybody having the same experience? What to do? Thanks, Vicente.
