Every so often, when I press the start button, I get a slightly longer crank time than usual. Maybe a second or so where the FiST turns over a few times before it fires up. It doesn't happen much but is noticeable when it does. It has done this since new and at a little over 6k miles it has happened maybe 15 times. Anyone else had this happen? I'm not worried about it being an issue, just want to see if it is common. Thanks.
