It sure does stink when you something that you buy for fun turns out to be anything but! No active error codes IS a mystery; but that funky swaybar connection sure couldn't have been helping the situation at all...
We seem to hear a lot about the battery being the source of a lot of the fun with these machines; it's never a bad idea to take a good look at them for potential trouble spots.
Anyway; I'm sorry to hear that you've been in it this deep; here's to hoping that you can find an easy and painless way out! Good Luck! Please let us know what you find...
