Humming Sound
We've had our 2014 GL450 for over a month now and are extremely happy with it. I have noticed a humming sound coming from the engine bay which lasts for about 5 minutes after turning the car off. I noticed it a while back and I don't think this is something which has developed recently. Has anyone else experienced this? thanks

Yes, my 2014 GL550 hums like this for a few minutes after turning it off. No idea what it is...

Sounds normal, the best sound is the pssst, after you turn the car off and are waxing or something and the suspension hisses and pssst'd at you. Though I was crazy when I first heard it.

Anyone ever hear a sound coming from rear wheel area if you turn the car off and hop quickly out, sounds like an electric screwdriver or drill turning for about 1 second. I get this randomly on my GL450 maybe like once a month. Pretty loud.
