Mine neither... I will be driving it to Chicago this weekend. Will listen on the highway. Mine comes and goes.

Yes, and it's driving me crazy. I plan to take it back to the dealer. In for a fight, I just returned my 2020 GLE450 on a buy back, and elected to get the GLE 350, and now the whistle noise. It start around 60MPH. It sounds like you blowing in a pop bottle.

Wowmichaelwow

Elaborate on the buy back or the return of your GLE450 please! I am very interested. I have nothing but problems with my GLE350. I have been using the the 2020 GLC300 and it feels a whole lot more refined than the GLE. I would definitely trade.

See thread below, around thread #121:

On by GLE450, it started with a check engine light, that gave several defect codes. I took it back to the dealer on Aug 30, and kept it until Dec 5 stating the issued could not be resolved. Bottom line they change many parts searching for a solution. Did not want the car back due to the issues discovered. I purchased the car in August 2019 and three weeks later the issue started with the check engine light. Take a look at the thread and it will give you the entire issues others had also.

How about pricing. Did you lose money when they took the 450 back? Did the original down payment go towards the 350?

Roadhog56

No money was lost, they paid me my down payment minus the mileage I put on the car. In the end I was not out of anything. It was a long drawn out process tho. In all about 6-8 weeks

I have the same problem. It's happened a couple times in a specific situation. Driving at highway speed, 60 mph.
As a strong gust of wind gust came in from the front drivers side, I can hear a whistle sounding like someone blowing air over a 2-liter plastic bottle.
Mentioned it to the dealer...car checked and nothing found. Frustrating.

Often this is the result of an air leak caused by a faulty window seal. To find/determine if you have a leak, roll up all the windows, turn on the A/C to max, and spray a water soap mixture on the windows where they roll up into the door frame. Then look for bubbles caused by air escaping from the inside. If you see bubbles you found your leak, and you can have the dealer dealer fix it.

Thanks! I will try that this weekend...

My 2020 450 GLE is also making the whistling noise. They have replaced seals etc. and still has noise. My dealer (Tyler, TX) said that they don't know how to fix it but they are aware of the problem at corporate. I will not drive it because it drives me crazy. It's my wife's car and doesn't bother her. Sad to pay so much for a car and have to listen to wind noise. My Cadillacs never did this.

mbgle

Thanks for the reply. I have not taken my GLE to the dealer yet because I have yet to read that anyone has received a proper fix. I hate to be skeptical but I doubt corporate knowing about the problem matters much. Agreed, so sad to pay this much for a car and have a noise that I have never heard on any cars I have had that cost considerably less.

makes me think twice about buying one of these. hearing other issues also. i'm not paying 80K plus to go through this crap.

GregW / Oregon

Go to almost any car forum and you will have these posts - more about problems than the good. Since one initial issue, NO problems including wind whistles and key issues in the last 6 months/6k miles.

Fastcars1969

yes that is true but this 2020 seems like its having many first year issues. could be worse i guess but it doesn't make the decison any easier to spend that kind of money. I test drove a 580 and it was nice but not totally convinced it's best in class.

I have almost zero issues so far with mine, and its an excellent machine. Pretty much every small nag I have is software stuff. The built quality is great, the vehicle is beautiful, and extremely comfortable.

My wife's GLE 350 is having the same issue. Took it to the dealer 3 weeks ago and the technician test drove her car and another on the lot then told her it was normal.

Welcome to Melanie from Tyler TX - kind of funny to me..

With the quiet cabin of the GLE - "wind noise" audibly can seem more dramatic than it is - but audible perception is audible reality - similar in level to having a dash vent closed when climate control fan is 5/6.

For customers who report this issue - we choose to use a Honda silicone product - tech uses a vinyl glove and applies the product lightly-but-evenly on the full front door seals - kindof "rub it in a bit"


In this application the Honda silicone lube works better for us than the MB Krytox "oil" - and better than GumiPhl.. the silicone lube will reduce wind noise - and so far has not needed a 2nd application

Look at this review, hahahahah!! damn, that whistle sonds HORRIBLE. Is not wind noise, is a whistle hidden somewhere?

tinman831

For those of you who have the whistle, if you roll down your drivers side window slowly, do you notice the noise increasing up to a certain point? I’ve found that I have this weird wind noise which sounds similar to a whistle but it was very faint. Once I opened the drivers side window, it got louder and then disappeared with the window all the way down.

Electric Lizard

From the video, the noise seems to start at about 180 kph or 108 mph. Is this been your experience? This will be my wife's car and I doubt 100+ mph is going to be seen much.

auntieshoque

What the reviewer in that video experiences is not even close to what we hear in our GLE. Ours is just a whistiling, not really loud, but enough to be annoying. It's almost as if the window was down a tiny crack. That howl that he heard in the video doesn't sound like a window/door issue - that's something else entirely... almost like something in the hood is loose and making a noise like a loud car horn. Our whistling is only at regular highway speeds (so around 100 km/h / 60 mph) and actually not all the time - it seems to only be when the wind is quite high and hitting the vehicle from certain directions. Others may have slightly different experiences, but it's NOTHING like what he hears in that video.

tommyr

Wow, that's an eye opener. If that is what people are talking about I really understand why they'd complain. Personally I haven't drive my truck that quickly

tinman831

The person in the video says the hood wasn’t closing properly which could be causing the whistle.

Electric Lizard

Does anyone have anything other than word of mouth that shows MBUSA being aware of this problem?
