“The problem is when travelling at low speeds or stop the car to halt able to hear a noise from the rear end. Like a metal hitting another metal. It has been only 1 month I bought the car and 1300miles on it. The car is making really loud noise when stopped and hear it properly. It is making cling cling noise. I really worried about this issue. I almost observe everyday.”
