I wouldn't worry about it too much. As they say crap happens. I'd look at it the other way, I'd rather get these repairs out of the way asap as opposed to creeping up on you later and possibly leaving you stranded somewhere. Also, if your worried about its quality, I'd say its perfect the way its is for you. If you see more issues, you'll get more dealer involvement to make it right (possibly forcing a buy back if there are many more issues) now as opposed to a year from now.
