Recalls aren't really bad things. They happen and more and more. It really shouldn't be looked at as cars being built worse but rather manufacturers being more liable (by choice and government pressure) for any engineering errors. 500k cars doesn't mean all or most or even more than a handful would ever have any issues for the part. It just means there is a consumer environmental condition that can exist that can lead to a problem. Be glad for recalls, it means you're off the hook.
