I would urge any camaro owner with an A8 that is experiencing these issues to read this thread (
http://www.camaro6.com/forums/showthread.php?t=510888) and post on it. The more posts and visibility we have the better chance we have of getting the issues to gm engineering. Post 24 is where I have posted the majority of conversations as it is relates to this shudder issue. Don't accept "that it's a normal characteristic" of the vehicle, it's not. I love my camaro but it's days out of service have accumulated to more than my states lemon law allows (for more than just A8 issues). I urge you to understand your states lemon law statues and do not accept being pushed around. I'm currently in the middle of a lemon law case with hopes that gm will finally admit to the issue and commit to fixing it. It would be overly nice of me to give them more time to resolve the issue, I'm hoping they can, but I'm not optimistic.
