Was greeted to a symphony of warning messages while driving. Started about two minutes into my drive. Pulled over turned off the car, restarted everything, and after a moment they went away. Any ideas? Or just the wonders of modern machine machinery?
Similar reports from W214 owners here that are not unique to the E53. It may be a loose connection somewhere that causes an intermittent signal issue with one or more sensors/modules. Or it could be a software issue. Either way, a dealership is likely the only qualified place to get a definitive answer. Even if the problem went away, I wouldn't trust it. My car had an issue saying emergency stop assist was inoperative and would come and go seemingly randomly. I thought it might be the sun blinding a camera or bug splatter blocking a camera or sensors. Turned out to be a loose connection in the steering wheel.
First thing I'd check is the tire pressure. I (as many others across multiple models) have noticed that the current assist systems are impacted by having tire pressure even 1-2 PSI below ideal rating.

Not saying you are wrong, but this seems unlikely. How would tire pressure affect these systems? Can you elaborate more on your post? A link to some discussions would be helpful.
With sub-2k miles, my money is on electrical gremlins. I don’t think it’s catastrophic physical failure - it all works fine. Either way, it’s not on my dime.
i got a performance extremely limited limp mode (with turtle icon) warning tonight while driving on the highway around 60ish mph. no observable trigger. car was jerky and transmission seemed to keep things below 2,500 RPM. after i got gas and turned the car back on - everything was gone. hopefully this doesn’t recur…
:I had a similar issue on a 2013 SL. It turned out that there was a rusted multi-relay box that had apparently failed maybe due to corrosion. It was a very inexpensive fix once the problem was identified but the dealer took several visits before i found someone with a similar problem in the following link. Need help for a big problem! Please read and respond. - MBWorld.org Forums
The rear steer rack failed on ours (9/25 build) within two weeks and under a couple hundred miles of delivery. It seems there may be a bad batch of racks in the supply chain. Luckily the part is common to 214’s and isn’t a bespoke AMG part - was back on the road within a week and no problems since - just passed 2500 miles.
did not get limp mode, did default to all assistance off, dampers to full stiff, etc. powertrain operated as normal, and there was no alignment issue with the rear axle it just failed centered one morning.

did a ~500ish mile round rip to SLO and back from the Bay and thankfully it didn’t pop up again..
I would take it to the dealer. When there are control module errors, the technicians can look up a code and see the recommended fix. With this new generation of E-Class, initially there were a number of software bugs in the control modules that could be fixed with software updates at the dealership. We are far enough into this generation that many of the control module software issues have been fixed. When the technician sees the error code, he'll have a better idea of what happened.
@E53DadWagon did you take the car into a dealership and did they find anything wrong? It seems like the control module software is fairly stable now, so I'm wondering if this is specific to your vehicle rather than a common software issue.
We own a 2024 E450 All Terrain, Obsidian Black, Macchiato interior, maple strip dash. Purchased new September, 2024. Love the car. Very glitchy and has been in the dealership a few times for UI/software related issues, an exhaust flap (?), failed rear window actuator, etc.
I actually found this forum sniffing around after a multiple system shut down yesterday. Driving to office and ALL driver assist functions failed at once with individual panes that had to be cleared - in traffic - to shut them up. Attempts to reset failed, car was clean/sensors clean. Called Mercedes in car. Documented issues with them, they referred me to dealer. Called dealer, they have me booked (again) for an appointment to drop her off. Always there for 3-4 days. Last attempt to remedy at the house last night was a hard software reset, which of course means ALL the profile data was lost. We are long term car owners who do all dealer service and this one is making me nervous about what happens when we go off warranty.

I did not and it has been fine ever since. It was exceptionally foggy that day, so wonder if that was an issue for one of the sensors?

During heavy fog, blizzards, or ice on the sensors, my prior Mercedes would show messages that driving assistants weren't available. I haven't yet received those messages on the E53, so I can't compare with the messages you received.
Your messages about stability control and rear wheel steering are beyond the sensors that would be obscured by fog. I would guess that something happened with the control module bus if the errors were across control modules or within a control module if one module controls all those features..
It looks like something more than fog, but it is possible that fog caused a software bug that wasn't handled properly and triggered the other messages.
