Take it to mechanic to diagnose. It could be anything from minor to major.

If at start up - fading with warm-up - this sounds normal (AFAIK - or can tell by the limited info).

Perhaps a dealer/competent indy may provide add'l comfort 4U

Thank you for the reply. However, the rattle sound is not at the start up. It is happen while I am driving around 15-25 km/h at around 1-1.5k rev. I bought my car in Cambodia, so there is no dealer to help me out. I took the car to the mechanic to diagnose, and they said they could not identify the problem and have me drive it for now until it completely break down.

This is the video of anther guy that has the same problem as mine.
