Noises and sound usually occur when something is lose, that is why tightening of nut n bolt is recommended after every 5k, get your car service from 3S and tell them after service i should not be hearing any noise be hard on them. In karachi we have good 3S service my car is soundless till today Alhumdulillah, there was a sound from front left when i apply brakes but it is now gone after service on 10k.
