to be honest i have been having some slow and no start issuse lately with my X as well ... sometimes for some reason when i turn the key nothing cranks ... but i have power to run the CD player and AC ... i just waited a few minutes in the parking lot and looked at my girlfreind then i tired it again ... I must say is kinda scary ... i think i take my X to the dealer ship it under warrenty still .. So far it has only done this twice with in the week ...
I am gonna check for starter fuse/relay and see if the humidity got in to it .. after all i seem to have alot of foggy windows lately .. i wonder if it could be weather related or just a peice that is malfuntioning
