I picked up the same Thor 2014 Hurricane 34E back in November. WOW! Sorry to hear that you have a lemon.
With my two teenage kids and I virtually living in it and beating it up for the past seven months the only things that have broken have been the automatic door steps, (the main bolt sheared off), and just today I had the rear bathroom fan motor replaced under warranty, (it was getting loud).
The overhead bunk uses Shwintek brand rails that have a history of using inferior Chinese motors. And, the original main drive gear is known to break. If mine break after the original, and extended warranties expire, I will replace the motors with good aftermarket non-Chinese units, and I'll have the drive gears fabricated by a local machinist if I can't find good off the shelf replacements.
Get everything fixed soon, as your warranty is about to expire, (like mine).
