Good to hear they may have found the problem. I do have the XM module too. Today, my dealer called to see indeed my car wouldn't start for them this morning (no surprise there!). I told them to check the XM module, hopefully this will be the root of my problem too.

I have the exact same problem. My '07 SpecB has only 3000 miles and if I don't drive it a day, the next day the car will not start. It is completely stock. There is definitely a problem here - BTW I already checked and my battery checks out fine. The car is currently at the dealer, and of course they could not find any problem. They will be keeping it over the weekend and I will guarantee it will not start for them on Monday!
