I had a similar problem about 6 months ago. My wing would automatically come up if i was sitting at a red light or waiting on a fill up. I thought I was going crazy at first. Then the not cranking thing started happening. I would go to crank the car, it wouldnt crank the first time then I would wait a few seconds, try it again and it would crank right up. About 3 or 4 days after this started happening I was about to leave work and it wouldn't crank at all. Had it towed to the dealer and they told me I needed a new battery at first, which they were happy to sell me for $180. Upon furhter investigation it wasnt the battery it was the battery cables that needed to be replaced. They were all rotted out!!! That replaced them in no time and it was about $45.
