I have a 23 and yesterday the driver side display went dead. pulled over restarted car still dead reset MBUX still dead. car sat over night started this AM worked fine. been noticing little glitches lately. Rear driver window would not go up or down for a day or two. Have an appointment Monday am car need a recall done anyways. Has anyone else experienced any of these issues. My guess is MB is going to say they can not replicate and not stored codes.

 

Have them check the 12v battery. I bet its bad.

 

Had both of my screens go blank shortly after I took possession of my new 2023 S580 for 3 or 4 days and then came back on their own just B4 a flat bed was coming to take it to a dealer. Happened after I got a low tire pressure warning, which at that time I didn't know II had to to reset. We were at our at our second home that has poor Internet coverage assuming poor OTA fixes in northern Wisconsin. But everything seemed to function including the cruise control. Guessing I got OTA fixes when I drove to a local town occasionally. The car has had zero issues since and extremely happy with it.. Have been very mindful to reset tire pressure with cold weather changes and making sure the 12V battery is charged sufficiently per my Mercedes Me on my cell. "Partially charged is OK, but if "critically" I put on a trickle. I do a lot of short trip driving.

 

It could be both ways, most common is just bad software, the other is actual screen replacement.

 

I had that happen. They ended up replacing the screen.

 

My screen was replaced as well. Not only blank screen but every single warning light illuminated.

 

Check your tire pressure, if it gets low, it can cause all those problems. Not kidding, it's a common and well known issue.

 

Mine just went black. It made for a fun drive to the dealership.

 

Did you try raising the pressures as suggested?

 

If the tire pressure is detected to be dangerously low, it shuts down in various stages & configurations. Why who knows or cares, the point is, you have to reset the pressure value so the MBUX doesn't think it's at a dangerous value.

 

I just had a flat repaired yesterday. Twice in the days before I could get to the tire shop the system registered a 17psi reading with no ill effects. How low is too low?

 

A couple things here to give it some perspective. A few people have had screen failures, it happens. More have had a firmware error where an ongoing fault create more faults, this escalates until eventually you get an MBUX crash, and you can lose one or both screens.

As seen in the car the typical scenario is that you have a low pressure warning (the symbol that looks like a cross-section of a tire) this warning will persist until you air up, and the system is reset by a complete shutdown. There is no specific time before things go to hell. In my case, I started with the low pressure from the usual decline as it was getting into the fall, at 1 psi low I figured it could wait until I gassed up to get air. The next day, I started to develop more faults with some of the driver aides, and went to air up, assuming MB had set it up so that these would only function with proper air pressure. But, the air was down at my usual station, so no air that day. It ended up being a few days before I could get air after, and both my screens went out during that period.

So that's what I saw, others reported a similar progression, although there have always been variance with what exactly faults, and how long it takes for the car to go from low air, to a blank screen. The fix is simple enough: You get your pressures set, tell MBUX that's your pressure in the associated menu, and you must get a full shutdown to reset the faults. The car then functions as if nothing ever happened.

That full shutdown isn't optional. Reports here are contradictory on whether it was fixed for 24, some say yes, others no, but the cars from 23 and back do not get a full shutdown unless the fob is out of range. Without that shutdown, no reset, so you've fixed the problem by adding air, but the faults remain. I also did just that. At the time mine went down, that was early days, and they didn't know jack about the cars. I had been thinking it might be a reboot needed, but all the techs knew was that the car should be resetting with each shutdown. That's when I bagged the key, gave it a couple of hours, and viola, fixed.

Now the problem is well known, and that the first thing the techs do with multiple faults is check the pressures, reset the value in the MBUX menu, then bag the key to see if it goes away. If it doesn't then it's a step down the flow chart.

The dead screens I can recall being reported went down differently: The driver was driving along minding his own business, and bang, no screen. It was not associated with a series of escalating faults.

Again, the fault issue may be fixed in 24, I cant say. But the OP is in a 23, and it was still going on with at least some of those cars.

 

UPDATE: Got a call from the dealer. Said they found code in control unit n133/1 instrument cluster U014787 communication with the control unit 'head unit' has a malfunction. the message is missing. found new software available in a26/17 mbux. the tested. they also performed the recall 20250500004 check and replace fuse box.

I was OK with all this. The service advisor then asked for my permission for one of the sales mangers to drive my car over night. I ask for more info on what he meant. He stated that they needed to drive the car over night to make sure the faults did not come back. I asked is this normal?? I have have had several high end cars and never have they taken it home for the night. I asked how far they were taking it if I let them and where would it be parked ie a garage (could not answer). He stated it would be 75-90 miles round trip. I asked who's insurance would cover any accidents or damage he could not answer. I asked would the fuel used be replaced like I am expected to do with the loaner you gave me. He stated it would not be. I said there is no way I was letting someone i don't know or where they are even taking my car. He then said that's fine I will have to check with the tech to see if I can release the car to you. At this point I am pretty pissed he is telling me a car I own he has to ask a tech if I can have my own property back.

Needless to say I drove right over and took my car. I went to see the service manger who was not in today, so then i asked to speak to the GM who was not available. We will see what tomorrow brings

 

No. There was no tire pressure issue. I parked the car and it was fine. The next time I turned it in on the screen stayed black.
