i took delivery of our new 2016 GLE 350 and instantly noticed a high pitched whine which i was told was normal exhaust noise and i would not even notice it. Well 650 miles later i am ready to dump the car. does anyone have the same issue? know of a fix? My wife loves the car otherwise. I have been back to the dealer and emailed Mercedes

I had the same problem with a 2017 model. Complained to MBUSA GAC, got the "its normal" response. Took them to task under Georgias Lemon Law. Car has 1200 miles. Last Thursday my dealer replaced a muffler and some other parts. Whine is GONE. Don't let them tell you it's normal or there is no fix.

I too am going insane with this high pitch exhaust/muffler noise. My dealer tells me it's normal but I find it hard to believe that MB would release a product with such problem and not addressing it. I've now put on 2000 miles and almost want to take a hit and terminate the lease early. If anyone with the same problem had resolved the issue please please share with us the solution. Thanks!

It is an exhaust problem. Mercedes fixed my problem after I started action under Georgia's Lemon Law. Replaced a muffler and other exhaust parts.

1600 RPM whine.

Had this problem with my 2017 GLE350. MBUSA and dealer told me it was normal. I started proceedings under Georgia's Lemon Law and guess what? The week before Christmas my dealer called to schedule a repair appt. last week they replaced a muffler and some other exhaust parts and the noise went away. That whine was so annoying no way was I going to live with it. Don't give up. Thy will fix it.
