TP has stopped vibrating

[4U2NV6]

My Touch Pro as of this morning has stopped vibrating. When it's set to vibrate it won't vibrate and just acts as if it's in silent mode but it does show that it's set to vibrate. I've tried soft resets, and since I have a Sprint TP on the VZW network, I'm trying to avoid the hard reset.

I'm thinking this is hardware related and I need a new phone. However, I purchased it brand new off eBay (30% cashback - only reason I did) so I would I go about getting a new phone if I need to. I did purchase the SquareTrade warranty just in case.
