I agree with your sentiments that the dealer seems to be the cause of this. I don't see any problem with contacting Mitsubishi Motors directly - it can't hurt things. It doesn't make sense in this day and age, but it's not the first time I've heard of it. In fact, most cars I've owned were used and it helped me learn what little I know about cars - I've had to repair my clunkers.
