@chqasim what year is your RDX and what engine size is it? Does the knocking sound increase when you increase the engine RPM's? What have you already checked and what have you laready tried? YOu can add a small vieo (with sound) to your question. that way we coud hear what you hear. Treat your video/sound file like you would treat a picture. Use this guide 기존 질문에 이미지 추가하기 for that.
Knocking sounds are never good and could be coming from the camshaft or (much worse) the crankshaft, pistons, valves etc.
