Last night when I turned my car on after it has been sitting in the parking spot for about 5 hours it started to make a loud clicking/squeaking noise from the engine. It became silent after the RPM's went under 1, which I normally let my car run so the engine warms up. I thought that it might be the timing belt, but found out that the Honda Insight 2010 have chains, which I believe won't need to be changed (correct me if I am wrong, please!). If I could upload the video I took of the sound it made I would attach it to this, but my car has 143k miles on it, it is a Honda Insight 2010. I've taken great care of it for the past five years under my ownership before me; it was used as a rental car. Anyone having the same issue or concern?
