I have been very lucky with my C in regards to have none of the serious defects early production owners have well documented on this forum. That being said, one nagging little thing happened about a week ago: I cranked the engine, it started immediately only to shut down with a second or so. This happened three times in a row. The fourth time the car ran just like it always did before and since.
The engine was warm, tank full, sitting level, engine dry (hadn't sprayed it with water) and I was using the original sentry key....in short there was no strange circumstances that would cause such a thing.
Well, I'm only a novice, but I would get it to the dealer as soon as possible, to see if they can pull up any codes. Maybe they will be able to determine what it was that happened. If so, maybe this is something new, that we can all learn from.
