Mine just started doing this a couple of weeks ago. Especially this morning, I'd say it takes almost a full 2 seconds longer to crank. When it's warmer in the afternoon, no such problems. Good to know, was starting to get worried.

Good to know, thanks Mike. I don't have a voltmeter, although I can get my friend to bring one to work tomorrow. Would reading the voltage via OBD2 while the car is running help me diagnose anything?
