Rocker, the best I can guide you here is to immediately get the car checked by Honda 3S first thing in the morning. Abnormality, big or small, relevant or irrelevant should not be taken lightly. Don't leave such things to guess work by geniuses like us. After you get it checked, you'll have some peace of mind as you'd be coming back insha Allah with problem rectified and solutions. Share whatever your experience was later on the thread so we can all benefit.
