If you turn on the function with the engine running after you have stopped, then turn the engine off, the car will continue to lower.

Seems to be pretty poorly implemented. It should raise and lower similar to how the seat and steering wheel moves to facilitate ease of entry and exit.

There is a faint buzzing noise (sounds like white noise) coming from the a/c control panel - anyone have any insight on whether this is typical for MB vehicles? I am new to the MB family - purchased my 2020 GLE 350 3 weeks ago (< 700 miles).

I noticed it last night on my way home - music was off and windows rolled up. The buzzing continues after the vehicle is turned off too.

TIA!

I haven't noticed that yet, could it be Vehicle noise compensation (VNC) from the speaker?

Hi from Slovenia (EU). I decided to join as I have some problems that some others are also experiencing. I have GLE 300d with approx. 15000km. Currently two major problems:
1. AC doesn't work properly. Its blowing hot air unless you choose lower temperature setting. Very very annoying.
2. All kind of "xxx inoperative" messages that come and go randomly.

Still waiting for MB to fix these problems.

I bought a new car last year (not a MB) that did the same thing about a week after delivery, they took things apart and there was a small piece of plastic from production in the HVAC that made a slight buzzing sound as it flapped when the fan was on. Could possibly be a similar issue.

Is anyone else having random issues with functions that work and then don’t but then start working again. I won’t list everything but here are some examples.
1. My center touchpad quit working with Android Auto and seldom worked with Mercedes functions. After a week it has pretty much started working again but not with AA. Wheel touchpads both work great.
2. Windshield wipers started a swipe or two each time the car started...after a week back to normal.
3. My console switch would raise the car but not lower it except occasionally it would lower and then raise back up. Now either up or down it lowers and then raises back up. The weirder thing it keeps repeating up and down multiple times until I get a message that the Compressor is Cooling, apparently it shuts down when hot.
4. My folding mirrors have reset to on 5 times. Started this after 3 months staying off.
There are a bunch more and my dealer sent off my list to MB Tech support 2 weeks ago. Still waiting for an answer. My dealer checked my AC vent lines a month ago and said no kinks.

For #2, I've seen similar on my A220. It's only happened when parking outdoors and I attributed it to dust/pollen obscuring the camera. In other words, it doesn't always happen but when it does I see a fine film of something that it clears away.

My car just did the exact same thing. Waiting for a tow. GRRRRR

New issue. Car has problem with shifter. It happens that it doesnt want to shift into Drive. We had to disconnect battery in order to be able to shift normally again. Interestingly when this happened, windshield wipers started working on their own, you couldnt turn them OFF !??!?
And it still happens few times a day (shifter problem), just not in most serious form like it did during the weekend. When this happens, screen is also showing all sorts of this and that inoperative errors. MB has serious issues with this model. Maybe they will recall early builds...

GregW / Oregon

What are you referring to? Previous post was about windshield wipers. Be sure to quote.

GregW / Oregon

Mine hasn't had a recurrence of the no-start issue in over 4 weeks since it was in the dealer last. Make sure you get all the available software updates done.

I met yesterday with the Mercedes Service Manager and the Shop Foreman. There is a TSB for your problem referring to kinked AC drain lines that can cause the vehicle to go in to limp mode and or not start. I have noticed that there is zero condensation draining from mine after I park it. I spread paper in my garage and after a 30 minute drive with full AC, I parked over the paper. Not a drop of water so mine must have a kinked drain and that could be contributing to my unique issues. If water reaches electrical components or a control module it might cause a short circuit or ground a live circuit. I haven’t had any major problems but have the tools to disconnect the battery if I do!

There are also quite a few new updates (some just out this week) to various components including MBUX and even the Key Fob. So much for OTA updates....all of these have to be performed by the dealer. I had to wait until the 16th for an appointment since I am leaving town soon. Will post results in two weeks.

I wonder if this very recent recall is relating to your situation?
"DAG determined that on certain MY 2020 GLE-Class vehicles, (167 platform) the air conditioning drain hoses might be incorrectly installed in the vehicle...."

ShrimpKing

Recently I experiencing some AC problem. like other member on this forum, the AC not working unless i turn the AC to LOW. If not low, even 60, its blow hot air. Sometimes I restart the car it fixed, sometime its not. Will call in today let them have a check.

hyperspeed

this has just happened to me. park is stuck. brake lights stuck. same error messages on dash and the car wont turn over.

will try disconnecting the battery and go from there

hyperspeed

hi greg, which battery did you disconnect? 48 or 12v? was it pretty easy to access?

GregW / Oregon

The 12V under the drivers seat.

• Raise drivers seat all the way up and forward.
• Remove the plastic cover in the floor.
• Remove the negative battery terminal briefly using a 10mm wrench.
• Reverse the procedure.

This should reboot the system allowing a start.

mrmotoguzzi00

This is really terrible

Pretty sure if I told my wife to carry a wrench to reboot her car she would just trade it in and be done with it...

hyperspeed

Thank you!

mrmotoguzzi00

How do we request this is a sticky note ?

tiri

Same here.

Maybe someone can come up with a quick disconnect switch that can be installed on the cable connecting the battery. Could make a pretty penny if enough folks have issues
