Typical canned jargon bs. At least now you have something to show your dealer.
Yeah, I think I'm going to wait until the first service/oil change to bring it up and have them check it then. The MB dealership is like 45 min away. I have about 7k more miles until my first service. I will keep track of how many times it happens until then, get video of it every time. So far it's happened twice since I got the car on March 13th (I didn't get a video the first time it happened though)
mine is at the dealership now to fix the HUD issue and the instrument cluster going black while driving. They have had it now almost a week and I have not heard a word. this is my third time in the dealer service department to fix this issue. I will let you know what I find out.
My follow up on the HUD repair that was made mid April. So far so good. Now approximately one month and I have not had one problem with HUD. I am hopeful that this issue was properly fixed.

Did they state what the issue with the HUD was and what they did to fix it?
They replaced the "internal cluster control unit". So far so good. one month and zero problems, 3 months will be the real test, if I go without any problems for 3 months my faith will be restored. I knock on wood as I love my 53 especially the driver assistance systems while on major roads, use it all the time, and you really need the HUD for that.

Thanks, that's good to know as I'm having issues again. Everything from blurred display to the HUD Inoperative message. Strange as it was fine for a while. But it's back!
Sorry to hear about your issues. It is very frustrating I get it. One common theme is that the HUD Not Operating issue will reset after some period of time of being off. At first, it would reset after sitting over night and after software updates is seemed to reset after being off for an hour or two. If this is your experience as well, it might well be the internal cluster control unit. Also my problems included the control cluster going black while driving. Obvious safety issue. Maybe this prompted MB to take a more agressive action to fix it. Don't know, just suggesting....
It's been in once for this issue and the dealer did a SW update. Right after getting it back, it still had the problem. Then a week or so later MB rolled out an update and the problem went away. So I didn't pursue any further. I have had one very random case of my entertainment screen going blank, but it came back when I restarted the vehicle. Wrote that off to a one-of.
It's been a few months and I know there's been probably two OTA updates since then, and now I'm back to the HUD problems. Not saying that's the cause. But you never know what they fiddle with in the background that has unintended consequences.
This last outing, it was not functioning when I started out for the day, and operating when I got back in after being parked for about 30 minutes. The opposite of what typically happens.
In any case, I will be contacting the dealer. This nonsense is unacceptable. Glad that yours has been sorted! Just curious, did replacing the internal cluster control unit involve removing the dash? Wondering how big of a job it is.
No dash work that I am aware of. The internal cluster control unit was accessed through the engine compartment with the hood up for access. I monitored my car status, including hood up, windows down, and unlocked, and the hood was up during the 3 days they were working on it. My car was at the dealer's service department for one week, though I think they were actively working on it during the last 3 days. They also took it for several test drives to confirm that it was working properly. Again the Mercedes Me app displays mileage so I could tell which days they drove it at least 10 miles. To be clear, I am one month with no issues at all, so great start. I will be satisfied that the problem is actually fixed once I reach 3 months with no issues at all. I will post on this site once the 3 months have passed and hopefully successfully.
Update on my fix to correct the HUD. Now 3 months since the dealer fixed the problem and I have NOT had a problem since, not one. I am now happy and feel like they have solved the problem. I love my 53 it is such a pleasure to drive and highway trips the driver assistance package is excellent, no complaints at all, the trips are much easier to make as my job while on the highways is to monitor and make minor adjustments as road conditions or traffic levels require. Best car I have ever owned. By the way and you probably already know this, "hey Mercedes" not only manages navigation but it also manages your music and cell phone. Really nice.
2024 GLS580. Picked up the car in January of 2024 and have had it in at dealer for what seems to be a total time of 2 months since HUD inoperative first occurred. software updates done and most recent fix was cat5 cable replaced. Telling me to reset by turning engine off and on is not an acceptable solution. Car was with dealer for what seemed to be 5 weeks and that is when the cat5 cable was determined to be issue and about 1 week later (with little driving) the issue has happened again. Mercedes has no idea why this is happening and has no fix for this an everyone should be aware of this. I’m going to propose the dealer can buy my car back at outstanding loan balance and I’ll buy a new vehicle. Complete BS on Mercedes part.
I’ve seen several times on this thread that you need to take a picture to show MB the issue has occurred. That is actually not needed because the tech at my dealer told the car’s system records when the error occurs and the techs can see the history of the HUD becoming inoperable. It’s as if MB is challenging our sanity in claiming the HUD issue legitimate by suggest that we need to document the occurrence by taking a picture of the error message.
Ugh that stinks. So it is supposed to be some kind of software issue?
That is what I believe, or they have a lot of bad units and it's "luck of the draw". I have yet to take it back. I want to know what their resolution plan is before I waste my time.

True, hopefully it is just a software issue but we don't know yet. I guess carry on with your day until you get an update.
I Took delivery on a 2024 AMG GLE 53 in December. Within the first month I started having Heads Up Display problems. First I would get warning message on the driver display reading "Heads Up Inoperative" and there would be no display on the windshield at all. Hours later and sometimes the next day after a number restarts, the HUD would be a holiday decorated display ... even the lines of the map had what appeared to be christmas lights on them, not legible, if anything just a distraction. Again after a number of hours or usually the next day, the HUD would appear to be operating normal. I took the car to the dealership ( mercedes of san antonio tx ) after the first time it happened and they said that the software had to be updated over the air. Unfortunately one month later the HUD is not working and repeating the error message followed hours later with a display with the symbols in jumbled colors and the lines very blurry. I am taking it back to the dealer. I really don't know what to do at this point ..... 8 more instances of this problem. If it is a software update problem wouldn't have updated over the air by now?
Any comments are more than welcome.
If you use the toggle button and go to the "i" for infomration it will bring up this screen. I have a 2025 GLS 580 and having the same issue. Sounds like a trip to the dealer is what's needed. I called the dealer and they were trying to convince me I simply wasn't managing my settings correctly (essentially I am dumb) - but I have had HUD for 10 years. First MB. I have never seen HUD not display on Ford, Cadillac, BMW ever....only my first Benz.
Same issue except this is a 2025 GLE53 Coupe. One week old. Exact same message as others are reporting. Doing some manual research, some suggested a soft reboot MBUX, anyone tried that ?. Given that some subscribers have mentioned it restarts on its own, it could be the case the hardware (Processors etc) cannot handle all the information rebooting might clear the issue. I will try it myself and report back. Regardless, not great, £107K RRP not good enough this is the kind of thing you read about with RangeRover not Mercedes!!.
I returned to the car the same day the issue occurred. Parked at 6:30 AM, returned at 9:00 PM, HUD worked normally. Very weird. I used the car again today, and there are no further issues. The dealer (who is very good) stated (via IM) that they have not come across the issue before, given the number of posts on this forum, and I can't believe that. However its clear that its software related.

Reason: Update
Sorry to hear aboaut your issues with the HUD. I had same problems and took it back 3 times until they finally got it fixed. Updating software did not solve the problem. The fix that worked was replacing the internal control cluster until. It has been one year now since they replaced it and I have not had any problems since. Zero. It was not software updates. They had to replace the "internal control cluster". Now all is good and I love my car. I hope you can get them to fix your issue. I highly recommend that you tell them my story about replacing the internal control cluster.

Glad yours was fixed. My last time in they said they replaced the HUD (it was in there for 3 weeks I believe). I'm still having the same issues. I've been too busy to arrange another trip in. Getting ready to set it up again. The part they replaced was 167-900-61-20-80 REMAN CONTROL UNIT.

Are they serious, trying to brush you off like that, I don't think there is another way to interpret the word "inoperative" which clearly means a fault, a system fault, a malfunction. How can they blame this on user error?

Thanks for the part number, much bigger repair than expected.

Yikes, that is move involved than I initially thought, glad it is fixed now though.
I just looked at my repair invoice. They replacdd the "Instrument Cluster Control Unit" Part # 177-900-72-18
They had my car for about 2 weeks and ran all kinds of test before they determined the proper fix as noted above.
this fixed my HUD not operating issue. Zero problems in about 1 year since the they replaced the ICCU.
Prior to that they updated the software twice, once for the HUD and once for the central control module. This did not fix the issue.
This is all I can tell you and I hope that you use this information by giving it to your MB dealer as proven fix.
