Had the car for 2months now. There is a rattling noise coming from either the trunk or back seats anyone had any luck identifying the mystery creaking sound in their G20??
Update on rattle with a solution:
Solution for center speaker rattle:
Cause: frequency of 175Hz causes the plastic grate to vibrate. The sound is created due to lack of silencing material around plastic contact points
Solution: remove grate add silencing material to cover contact points.
