MBUX Reset Itself!
Another day, another MBUX Story!
On my drive home last night, while driving at 140 km/h (86 mph), all three MBUX screens went dark. Fortunately, the digital speed and gear display were still displayed, but everything else—including Apple CarPlay, which I was using for navigation—stopped working.
After about 3-4 minutes, the MBUX system restarted, but everything had been reset! My car was de-linked from my Mercedes Me profile, and the system language was set to Arabic! (I live in the UAE but don’t speak the language). To make matters worse, my seat and steering wheel positions went into default settings while I was driving—a serious safety concern. During the reset, I also noticed the ambient lights pulsating in different colors, which was both distracting and strange.
Once I got home, I had to re-link the car to the Mercedes Me App, re-add my profile, recreate the Apple Car Key, and reactivate all the digital extras—essentially redoing all the setup steps from when I first received the car.
I’m not entirely sure what triggered this. The only potential cause I can think of is an OTA Software Update notification I received earlier that day (update for the communication module - though the update hadn’t been installed yet).
Honestly, this experience (including all the other issues I have faced) has made me question whether I should keep this car. I’m seriously considering switching to something less software-dependent.

Is this the first MBUX issue since roadside assistance reset it by disconnecting the battery last October as you mentioned in this post? That prior issue was suspected to be caused by a software update, correct?

How do you know? Do you have automatic updates disabled? Is it possible it was installed and that was the cause of the reset?

Yes, this is the first time since the roadside assistance last year. By the way, that visit was followed by a more detailed workshop visit where they did a full software update and also conducted a mandatory factory recall for the MBUX "Control Unit". It was also software related but I could never get more information on what exactly the dealership did.

Welcome to the club! You’ve joined a group of fellow W214 owners who are navigating the wild waters of screen reboots like you. Seriously, check out all the posts on the subject! Dealing with these screen resets is as fun as getting a root canal without anesthesia. The reboots are as unpredictable as a toddler in a candy store; they can happen at any speed, even while you’re trying to park. MB insists these hiccups are just software-related, but I’m more skeptical than a cat at bath time.

Let me tackle your question with a splash of tears: still, no fix in sight! My dealership's loaner car is like a golden retriever on a leash—adorably helpful but definitely keeping me in a tight space! I'm basically just taking it for a stroll around town. But hey, I'm Grateful for the loaner wheels, though!

Is the loaner running the same software version?

Going to an C-Class from an E-Class is quite a downgrade in my experience let alone to an A/B-Class, I mean for those who first came to Mercedes, it is a good starter vehicle but at that point almost all economy brands can offer a better vehicle (in my opinion anyways).

So I'm looking to get a leftover 2024 E-class very soon and I'm just learning about everyone's issues with MBUX. Question. Is the car still driveable when the screens go out or does it leave you stranded? Does restarting the car at least bring the MBUX screens back to life so you can keep driving? I know the OP said he was able to drive home and MBUX reset itself but he had to login again and sync his account. What about other people?
It reminds me of when I used to have a Windows PC and it would crash and reboot randomly, which was very annoying. I stopped using Windows.

I recommend that you have your service department update the software and check for errors before taking your vehicle home.
Regarding your second question, yes, the car remains drivable even when the screens shut down. Most people only experience screen reboots and a self-restart of the displays immediately after shutting down. I hope this helps!

I want to clarify that not everyone is experiencing screen issues; those of us who do, including myself, share our problems here. However, the majority of users do not encounter any issues. Overall, the car is excellent—luxurious—and I have thoroughly enjoyed driving it.

I was just blown away at how nice the ride is on the new E-Class compared to my 2012 E-Class. Comfort-wise, the new E feels like the previous gen S Class.
I've rented the new BMW 5 series several times and driven it hundreds of miles while traveling and it just doesn't compare to the E Class.

The Car is awesome and drives very nice, really liking mine. Rides so much better than my 2019 213. So far at 1400 miles no issues with the screens yet, hopefully it'll stay that way. I enabled a security code to prohibit automatic updates as I want to fully study any update before it just installs it automatically. I figure why mess with a good working thing and possibly create a new problem by doing a software update when not absolutely necessary..

Thanks for the quick response. When I test drove the E350 today I even asked the salesman if they would do anything to the car before delivering it to me if I decide to buy it (just like you mentioned) and he said yes, that they send the cars through the service department and make sure there are no open recalls or necessary software updates before delivering the car to me.

Wanted to say sorry for the people who are experiencing this issue. Didn’t mean to sound inconsiderate in my above post. I could be a member of the blank screen club in the future too but so far it’s ok.

Although I’ve had my share of MBUX reboots, and I’m mostly fine with those as everything comes back in a minute or so, this was the first time the system completely reset itself to default, erasing my profiles, de linking the car from the Mercedes Me app and resetting my seat / steering profiles while driving!
With that said, mechanically the car runs sound, the drive is very good and as someone mentioned here, it really is like a mini S class. But this being my 3rd E Class, I’m somehow afraid of what future holds for us - less software, the better.
I am slowly trying to convince my wife that (for me at least), the 911 is the way to go……

Unfortunately I have been in this club since I picked my car up in June 2024. Ranging from a completely “bricked” car to check engine lights - all purportedly due to software glitches.

It's very annoying, and despite it happening daily, I'm still caught off guard and startled each time. While I don't mind if the music stops, I do care about losing the destination satellite settings. It's incredibly upsetting when I'm in reverse and trying to park, as I certainly don't expect the image to cut out. I also dislike getting new engine warnings after a shut-off. I have experienced break-related warnings, Tire pressure, and Collision warnings... Come on, Mercedes-Benz, please issue a patch to fix these issues.

I think a lot of W214s have SW problems
I wonder if there are any (or how many?) accidents caused by these "non-majority" software problems? Even 1 would be too much, eh? This forum sure has a lot of threads and posts about SW problems - I'd guess hundreds at this point.
I'm avoiding W214 until these problems are reliably fixed, even as a loaner, but I'm a bit of a safety zealot.
I have a W213 and it's great now that the dealer fixed my occasional transmission jerk (2-3-4 up and down) with a recent transmission SW update and a few Stand Still Adaptions, but it took 2 years for this fix to happen, and I still prefer the W212.

I identified a new problem today after last weeks MBUX reset.
The head-up display is both skewed and "zoomed in" to the point that some prompts (such as proximity warning and navigation) is partially concealed. Even with the adjustment options I cannot seem to fix it.
Do we know if there is a way to recalibrate it? I will try to send a picture later today.
