Seat memory is acting weird
I have my seat position saved to memory 1. Ever since I programmed it, the seat and steering wheel would adjust that position automatically upon start up. For whatever reason, it’s no longer doing that. I have it manually hold down 1 to return everything to its proper position. Any idea what’s going on?

Why is the seat position changing to something different from your settings? Someone else driving the car meanwhile or are you referring to easy entry/exit?
The car is not supposed to adjust seats automatically to any seat memory setting (excluding easy entry adjustments). The car is supposed to automatically adjust seats according to the selected profile. Even then if you apply seat memory position 1 while your profile is active, that setting should be stored to your profile and you sort of should get memory #1 adjustments when next time entering the car and selecting your profile (if not already selected).
I've just found this profile memory a bit unreliable (mainly on wife's car, our W223 is hardly driven by anyone else).

Sorry, I should have been more clear but the seat doesn’t normally move but the steering wheel does (I have comfort access enabled for the steering wheel but not the seat). What’s happening is that upon startup the seat will move to some random position. I have to hold down 1 to move it back. I’m using the same key as before.
I think it might be moving to seat memory 2 or 3. I’ll have to check.
Anyone else experience this?
If it randomly trying to load 2 or 3 maybe I’ll just save the same position for all three spots.

Same thing is happening to me, it's not doing every time but often enough. I don't see any rhyme or reason to it. Sometimes when I start the car, it goes back to my profile, sometimes it does not. Just another one of all the stupid gremlins in this car. By far not my most hated one.

Many times the Easy Entry/Exit function on my '21 S580 does not position the steering wheel/seat in the driving position when I start the engine. I end up having to press 1 on the door memory to get the steering wheel/seat in the driving position. It does, however, always position the steering wheel/seat for exiting the car when I shut off the engine and open the door.
Here's the crazy thing I stumbled upon. If I place my iPhone on the wireless charger first, then start the engine, the Easy Entry/Exit feature will not position the seat/steering wheel for driving. If I hold off putting the phone on the wireless charger until after I start the engine, the Easy Entry/Exit feature positions the steering wheel/seat perfectly for driving every time. Don't ask me how I ever figured this out, but it seems to be true.
Anyone else have this issue with the Easy Entry/Exit feature?

Same issue on my '21 S580! The wireless charger seems to mess with Easy Entry if I place my phone before starting, the seat/steering won’t adjust. Waiting until after fixes it. Weird glitch hope Mercedes pushes a software update soon.

Alexie,
Well, that actually makes me feel better!! I thought I was going crazy. I might still be, but at least I've got a little company! LOL! I'm not sure we'll ever see a fix. Unfortunately, I think it's been too long now for MB to spend any time on a model year 2021 software fix, and so far it appears to be just the 2021's.
I think MB has "frothed" themselves into a technical mess regarding the whole MBUX system and all the model-specific issues they seem to have. They're so messed up at this point, I don't think they even have a clue as to how to address these issues moving forward. They just tried to incorporate too much, and it has come back to bite them in the butt.

It's brilliant that you were able to notice that.
I personally don't use the easy exit/entry feature, so I wouldn't know if mine does the same thing but I'll hold off putting my phone in the charger until after the ignition.
Who knows what other features it might mess up loading lol

I currently own a 2024 E450 AT that occasionally "re-adjusts" the seat position, even without using the easy-exit feature, and am close to trading it in for a 2025 S-class, not due to the MBUX glitches (but because of mediocre LED headlights) so hearing of similar problems with the S is almost reassuring.... But relative to the incorporating too much, just viewed a review of the S-class by "SavageGeese" who panned the car due to this "too much". issue. He said it was as if the engineering guys had "technical diarrhea " and just splattered it all over the car without considering the usability of that technology.

I have noticed if I accidentally bump the seat controls while fiddling with other door/seat/window controls, it will move the seat ever-so-slightly, and when this happens, the car thinks I've adjusted it to another position. This appears to override the memory function on future entries until I touch memory 1 again to get things back in sync.

I don't know how 'mediocre' the W214 headlights were, but if you're not getting the Digital light on the W223 (I have no first-hand driving experience with it), the regular LED light isn't that impressive.
The auto high-beam activation is kinda cool with the pattern looking like a opening/closing light curtain, but not THAT great.
Just so you know.

So now I think this goes beyond just putting the cell phone in the charger--I have confirmed 3 times over the last 2 days that if I put the driver's seatbelt on before starting the engine...the Easy Exit/Entry function won’t adjust to the driver position as well and I have to press a seat memory setting (like "1"). FYI--I did not put the phone in the charger at this time. Usually, I get in the car, start the engine, put the seat belt on, then put the phone in the charger. Everything works fine if I do it that way--but I think my car is possessed! LOL!
If you put your seatbelt on before starting the engine, does the Easy Exit/Entry function not adjust?

This may be a safety issue to prevent the seatbelt from tightening too much for smaller drivers, especially if there was a larger driver in the car just before?

First thing I do when I get in the car is hitting the ignition switch, followed by the auto stop-off button.

SURPRISE! There's a software update for the seat memory/easy enter/exit module. I received the update yesterday, and now it no longer matters what I do with the seatbelt or my cell phone or even the order of operations getting into and starting my car...the seat now always pushes back and the steering wheel raises up when I shut the engine off and open the door, and returns to the driving position every time I start the engine. Happy camper!
