I finally got a diagnosis from the dealer yesterday. They ended up removing the dash (or at least part of it). Turns out some wires began to rub against the firewall. This caused some melting and eventually several shorts. On top of that, they found one of the cylinders was misfiring due to a wire grounding out before the cylinder as well. All said and done, the repair will be a little over $500 >

Has anyone else here gone through something like this? Just doesn't make sense to me being that the car is not that old. 2010 with ~65K mi.
