Interesting, I have the same problem now !

 

GLE350 Exhaust Noise Solution
I recently purchased a 2017 GLE350. With the new car excitement, at first I failed to notice the annoying exhaust whine or moan at 1500 rpm. But when I did I felt I could not live with it. The dealership was no help and refused to concede that the car had a problem. Back at home I looked under the car and immediately deduced that the problem would be easy to solve. So with a little roofing flashing, two large hose clamps and ten minutes of time I cured my moaning GLE. The finished project is not the best looking thing but the car sounds perfect now.
The solution was to roll up about a 9" x 10" piece of aluminum flashing and slide it into the fake exhaust port from the outside. Then slide it on to the exhaust pipe and clamp it tight with the hose clamp. It may need to be adjusted to looked good. Then do the other side. See the attached pictures. I plan to take the car to a muffler shop and have a professional job done.

 

I fixed my recently bought Gle350’s exhaust whining at 1500 to 1800 rpm by cutting both exhaust tubes and adding new ones facing down and outwards, $150 at a muffler shop. Car is now very quiet and no whining noise. If you buy a nice, clean low miles 2017, 2018 GLE350, this is the solution.

 

This is sort of why I like buying older models because a few years into the product being in the hands of consumers, there's a lot of issues that get worked out. Rather have a 2-3 year old model with minimal problems than something brand new with you know what!

 

Yes its awefull I hate it too noisy AGREE

 

Have you gotten them to take a look at it yet? (dealership)

 

This isn't the first model Mercedes Corporate are being ridiculous about. The GLC is going through some huge issues as well and MB is of no help... still. They're go to answer for everything is "it's normal" or they pretend there's just no issue at all, even after all of the complaints. I'm pretty discouraged from being an MB customer at this point as well, and I'm sure there are many more.

 

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

 

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.....

 

Perfect! Thank you for explaining which parts they replaced!

I doubt they'll create a recall... they seem to just tell people it's normal until people realize it isn't... :|

 

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.

 

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

 

Jnorris, do you mind letting me know which Georgia dealership you used to fix it? Hopefully it was one in the ATL area.

 

Muffler and what other exhaust parts exactly? There aren't many parts pertaining to it..?

 

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.

Jnorris541 - Would you mind posting more information about the specific repairs that took care of your exhaust noise? Or tell us which Georgia dealership you dealt with? Thanks!

 

Mwecedes will fix. They will replace some exhaust parts and problem will go away.

 

It is exhaust and mb fixed mine by replacing some exhaust system parts.last week

 

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.

 

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.

Mercedes GLE 350 popping noise

Hello, I have a 2016 GLE 350 with approx. 12,500 miles on it and I'm not sure if it is the same noise others have noted but, when the car is stopped but not in park, I hear a popping noise which sounds like it is coming from the center front. It's just a quick pop and it's gone but, it usually happens several times while the car is stopped. I have taken the car to one of the local Mercedes dealer and they could not find anything however, I am going to take it to the other dealer in my city and see if they can find anything.

 

Do not give up hope!!! If you read my posts about my GLE 400 you will see it was a very troublesome vehicle. I am not one to take "It's normal" or "there is nothing we can do" for an answer if I know I am right. I took my complaints all the way to MB corporate (regional person was of no help). I told the dealer I was ready to put a vinyl wrap on the car with big lemons on it and listing the issues with the car for everyone to see. After a month of back and forth, the dealer bought my car back at market value and corporate paid the difference (with the condition I would get another vehicle of equal or higher price) to get me a FULL REFUND of the original purchase price of $73K. I wanted a new GLS 550 anyway so it worked out. So once again, DO NOT GIVE UP, and good luck to all of you.

 

I purchased the GLE 350 in April and immediately noticed the problem. At first Mercedes denied the existence but after pressing the issue the service manager at the dealership ( who was very pro customer) discovered it was Harmonic Resonance in the exhaust system created by the through the body exhaust ports. His research also showed that at that time there were other identical complaints. The noise is now gone due to their "solution!! The solution was to eliminate the through the body exhaust pipes and install the system from the 2014 model that does not go through the ports but rather exhaust gases are point towards the ground and the ports are not functional--just two empty holes in the rear bumper--NICE!.
Upon realizing this I contacted Mercedes Client Service Center and was advised that they were not willing to re-engineer the vehicle problem and per their research of the problem "was within specs" to which I say "bullshit"!
For Mercedes to turn their back on a nationally know defect is unconscionable!
SOOO--I wanted to get rid of this monster and was going to turn it in for a LEXUS 350 only to find that the manager looked at the vehicle and said "this is a Mercedes with the noise problem that has been retro fitted"--We rather not take this vehicle in on trade"!
SOOO- next stop is the Mercedes dealership upon arrival of the 2017 models which I figured would have the problem corrected. WRONG--took it for a ride--exact same problem. SO Mercedes is aware of the problem now for two model years and refuses to do anything about it.
SOOOO- tell your friends and colleagues the story and advise them to not buy Mercedes. They provide lip service vs real service and hide behind the term "within specs" to avoid addressing this issue. In my book they are a not the fine company that the purport to be. Never again will I drive a Mercedes and BTW--I own three right now!!

Same thing here. I just bought a GLE 350 an noticed the unbearable exhaust noise on my first ride home. Took it back to the dealer, went through two days of service with the final answer from the dealer being "This is how the new GLE sounds, there is nothing we can do". I called Mercedes Benz customer service and they also told me that there is nothing they can do about it and that the warranty would be void if I modified any part of the car to try to fix the noise.

I am very disappointed at Mercedes Benz. I'm stuck with a $60k car that sounds like an cheap motorcycle. DO NOT BUY A MERCEDES BENZ GLE !!!

 

I have bought GLE 350 last week. I didn't notify until I took it out to home that there is strange sound coming out from back. I suddenly checked the internet and found this forum and notify that it is from exhaust. I took it to dealership and checked it with the people and they were kept saying normal but when I showed this forum, one of mechanic said they changed muffler and some parts with other customer one week ago. And he said he will order the part and they will fix it. However, 3 days later, dealership called me and said my car has no issue and they want me to pick up my car without touching anything. I am so disappointed with service and quality of GLE 350. Please, don't buy this car whoever read it until Mercedes fix this issue.

 

MB GLE 400, 8200 miles, bought Feb 2016


In the shop multiple times (Trans hanging up in 5th gear at highway speeds, exhaust noise which was solved by a complete exhaust system replacement, high speed vibration, and several transmission reprograms.)


Well, the car is in the shop again for the last 6 days. The transmission was taken out and completely disassembled. There was a lot of slack between 2nd, 3rd and 4th gears when the car was slowing down. It was almost impossible to come to a smooth stop when in these lower gears. Today I was informed that there are 3 sizes of shim kits that can be installed and that the one installed in my car was the largest available. I should get the car back tomorrow (not that I want that lemon anymore) so we'll see.
Mercedes has not been very willing to help so I have taken it to their higher level. I want them to buy the car back because it has been a problem since day one. The lady at corporate seems nice but the field rep is apparently not very helpful.

 

I just heard the noise in a GLE 350 2017....after looking at it, I believe, it is that the tips of the mufflers don't flow into the exhaust pretty tail pipe...in other words, there is a break or uneven flow from the "real exhaust" to the part which is attached to the body....this is can cause an "extra" sound break at the lower RPM's everyone is talking about....If any sound or mechanical engineers on this forum, it would be great you can give us some input or possible aftermarket solutions.....
