While speeding up or taking sharp turns, these noises may be much more prominent.

You may also find unwanted dampness on the floorboard or on the ground below where your car was parked. These marks are more prominent on the passenger’s side. Moreover, if this problem is left unaddressed, it can even damage internals and outlets as reported by customers.
