i tried to start my car one day and nothin was happening. it turns out my battery sulfated in one of the cells and failed the load test when i brought it in for maintenance. i never leave my lights on and have no aftermarket audio or any other source of strain on the battery. maybe i just got a bad battery from the factory, but i was wondering if anyone else has had the same problem and if theres something faulty with the electronics of the xB.

I never had that problem, where are you located? Near the cold? If not then maybe it was just a defective battery. Hope they took care of you at the dealer. :D

im in sunny so cal (well not so much right now), so the cold is definitely not a factor, but the dealer did take care of everything really quickly and said they couldnt find any huge issue that would lead to the battery problem.

so glad to hear they took care of you, thats pretty good though! How many scions made and u are the only one with a defective battery. Thats still pretty good! :D
