Purchased my 2017 GLE 350 12/29/16. Noticed engine/transmission noise at low RPM's when going throw D1,D2,D3...etc. I looked at the tail pipes under the car and you can clearly see that the tail pipes do not extend far enough to permit the noise to out the openings in the back fender. When in the cabin you can hear the engine noise and the sound of the transmission humming and shifting. I have owned Lexus and Cadillac and never experienced this type of noise. For a $65K price tag and a Mercedes you would expect better performance.

I just got back from driving to Florida and rented a Chevy Suburban and drove it for 10 days.... cabin was quiet and never heard the engine/transmission. When I got home and jumped in to my new Mercedes, I could not believe the difference in the engine/transmission noise....... so much more in the GLE vs a Chevy.....really?

Have appointment at dealership, we'll see what they say. Got great feedback from this forum. Anyone that has more dealership fixing the problems, please share as it will help us all! Thanks

Took my GLE to the dealer today.... explained the issue with exhaust sound and showed them this forums multiple reports of similar problems. They said a tech would drive the car and they would call me. I was fully prepared for a long drawn out process to get this issue resolved. They just called and said Mercedes acknowledges that there is a problem and that they have ordered a new muffler system that will be here by Tuesday. Amazed at how easy this was! Will post when work is completed and the exhaust system sounds.

Picked car up today. The car sounds great as all of the annoying sounds are gone. The muffler was replaced with the exhaust pipes that curve down which defeat the resonating sounds that were created in the bumper portals. All work was covered under warranty. One has to wonder if Mercedes will create a recall for all of the GLE 350's that have been sold.

ps.. I was give a C300 as a loaner that had the exhaust that went straight thru the portals in the bumper and it did not have any of the annoying sounds that GLE had.....

Today I called Mercedes USA customer service to advise that exhaust sound problem was resolved by dealer installing a 2015 muffler system. Wanted to lodge complaint that I purchased a 2017 GLE and that German engineering solution was to use 2015 parts while I still have exhaust ports that are now holes in my bumper. Agent put me on hold and finally came back and said sound I heard was normal, but dealer accomadated me by using 2015 muffler system. THINK ABOUT THIS.... they admit no wrong engineering, however the dealer just decided to replace entire muffler system at a +$1000 warranty cost even though there is nothing wrong..... I just completed a JD Power survey and detailed the exhaust noise issue in the cabin and the poor response from Mercedes Corporate.

This was my first and LAST German Engineering Mercedes......... They have a serious engineering problem with their 2017 GLE 350 vehicle exhaust system and they will not step up to admit it and provide owners with a satisfactory solution. Individual state lemon laws.........stay tuned
