Just bought a new 2010 Civic VP a few days ago. First couple of days when starting the engine everything was OK. Yesterday morning when I went to start it up I noticed a short split second grinding sound. The engine had no problem starting and ran fine. When I left work later in the day the engine cranked fine. I figured it was just a one time deal. This morning when I went to start it, it did the same thing and made the same noise. This time I shut the engine off and tried to restart it and it cranked up just fine. Anything I need to worry about here. Car has 250 miles on it.
