It's under warranty. Take it in, and be sure you get a paper copy of every repair done during it's warranty. You have a bumper to bumper 36K warranty, then a 50K drivetrain warranty. Use it!
Again, be sure you have all copies of paperwork for warranty work. If a same fault happens again after warranty, you have a strong chance of having it covered after the initial warranty expires if you have the documented proof that you have had it repaired before.
It is better to keep your mouth closed and let people think you are a fool than to open it and remove all doubt.
