I'm still trying hard to believe your story. The Mazda 6 is generally solid but there have been lemons (which can be said for any car maker). Yours might be one. Just seems hard to believe you encountered 2 incompetent dealers and had so many unrelated problems at once, none of them being fixed. Also many dealers tend to replace trannies rather than fix them. And yours is the first I've heard with those problems. Is the car the 6 or 4 cylinder?
