This is shaping up to be a good Lemon Law case. Keep copies of all documentation, only communicate in writing, and let them know that they will be dealing with a pretty expensive solution if you have to end up in a lawyer's office. PA assesses attorneys fees and carrying costs and mandates a full refund in addition. So, if you keep this focused as a dealer problem, don't do anything to mess up your warranty coverage like get your buddy Bubba to put on some aftermarket parts, , you will get this solved or get a new rig.
