I bought a 2020 CPO Gle 350 earlier this year.
At least once a month, I get this issue that whenever I start the car and put it in reverse, the main screen goes black and shows the message system inoperative. It stays on for few hrs . Restarting the car does not help it. It goes away after a day.

Initially the dealer said a software update would fix it but now they say it will require us to replace the controller unit and that is not under the ELW warranty I bought. Has anyone else had the same issue? Any advice?

Try an MBUX reset when this occurs by holding Star 🌟 and TEL buttons until the screen restarts. I get this sometimes after car washes.

I would question the claim that it is not covered under the ELW. In the US, the ELW covers the Command/MCS system. Since your car appears to be set for KM, I guess you are not in the US.

I received that exact screenshot Thursday for the first time, backing out of the garage heading to work. The only thing that was effected was the camera system. I restarted the vehicle and still had issue. Went to work. When I started the vehicle to go to lunch camera system worked fine. No issues since. I did take a picture of the screen to show my service advisor at next service.

This happened to me, once, about a month ago. After returning to car, a few hours later, it was fine.

This happened to my 2023 one time, it corrected itself the next time I drove the car. I had the dealer look at it and was told this is a known issue that MB is hoping to correct in a future software update.

I is a known problem in Europe, lots of MB drivers are afected and not only the GLE Models.
It seems that MB has already a Software version to get this solved, I will get it next week installed in my GLE.
I was complaining about this errors for months and all cameras and some cables were replaced on my car, but few days later the black screens were here again.

I also asked here long time ago, but nobody reply to .

yes I took my GLE in a week ago for service and they did an update on software for my MBUX too. no Black out issues though.

Just happened to my 2021 GLE63S yesterday for the first time. Hope it's gone when I drive it next.

I had never read this thread until early this morning. Thought to myself, "well that stinks." An hour later I hopped into my 2020 GLC 63S, put it in reverse and this error pops up for the first time, ever! This string cursed me!

The good news is when I drove out to lunch a few minutes ago it was gone. Oh......K.

If that is the case, it could be a bad OTA update to the control module that handles the cameras.

This is my thinking as well.

Problem is, if it is not common or if MB doesn't acknowledge it, then they might never issue a fixed version of an OTA update. Maybe there are also certain conditions/parameters that specifically causes run-time error in the system but it is hard to know.

For other models, there has been recalls to the backup cameras but that was older models like W205 and W213.
