Thank you very much for your post, RedFox. I bought a 2017 GLE earlier this month, and it has the same irritating exhaust noise related to the engine RPMs. I plan to talk to my dealer in Houston but anticipate they will say the noise is normal. (The salesman has already told me he is not aware of any complaints about the exhaust system.) I would like to be armed with irrefutable proof that Mercedes Benz's is rectifying the problem at no expense to the car owner when I take the car back to the dealer. Could you possibly post a picture of your invoice showing the work done on your car? Do you have any more information regarding this problem since your earlier post? Thank again.
