Each morning, it takes a little longer before the engine turns over on first start of the day. Every other start during the day is normal. This has been happening for a week. Yesterday, the dealer tested the battery, and they said it was fine. (On my inspection, battery shows the "OK" blue ring in the battery inspection window.)

Why is this happening?

I have had the same thing happening. I dont know why. The battery is good too.
Actually I had these periods over the years... and the starting issue goes away.
It probably isn't even an issue. As long as it starts from the first try. I suspect it has something to do with the gasoline quality.... maybe temperature outside, etc.
