Buzzing noise from GL450
I have a 2012 GL450 with 90K miles. Recently I found the car was making buzzing noise when running. When the car is about to stop, for example before a traffic light, the noise will stop. Other than that, the car runs OK.
The noise is very simiar to what someone posted before in this video
It felt that the noise was related to some electrical parts.
Had anyone had simiar issue before? I really appreciate if someone can help find what the problem is.
