This is the second time during my ownership of the car that it hasn't started the first was due to a dead battery), during the last week it has been stuttering when turning. I think the battery finally gave out, anyone have any idea if that's the case or would it something else?

 

Did you have it inspected by your local dealer? They can help out to determine if it might be something other than the battery. -LT

 

This is a few months late, but a few folks at Club Scion tC had similar problems and found success.

(Not to be a stickler, but this thread is also in the wrong section.)
