Perhaps the "Consumption" display could show warning signs that indicate an impending problem with the 48 volt system. I suggest you should check this periodically, maybe at least once a day if you have concerns.
I'm not sure what display of battery/charging is incorporated into the latest MBUX. On my '19 CLS53 (no MBUX) this display is accessed by selecting "Vehicle" and then "Consumption". The green bars show "Charge %" which is NOT the amount of charge on the the Lithium battery. It is the percent of charging BEING APPLIED by the MGU to the batteries. I complained to MBUSA that we need a display of the charge level of the battery such as is provided to the EVs, but no such luck. Maybe with MBUX try saying "Hey, Mercedes, what is the charge level on my batteries?"
Two samples of this display are attached below. The first is typical of "normal" driving where the "Charge %", the amount of charging being supplied is 5-10% of the maximum output of the MGU over a 30 minute period (you can select 60 minutes also). The second image was taken during the long, 15 mile descent into Denver from the mountains where the charge occasionally reaches near 100%. If your system is operating normally, you should see displays like this and if you become familiar with how this display looks under various driving conditions, you might be able to detect an impending problem. Let us know if you see anything anomalous.
This is great info. Unfortunately the MBUX equipped 53 models no longer show the battery life percentage as they did on Comand. We only have Fuel consumption shown.

Yes, I am just realizing that. Thanks for posting this update. The answer must be to keep the 12volt battery charged using a home charger and trickle charger whenever possible 'cause we don't have any way of knowing the status of either the Li battery. Is there some remote display that indicates the voltage and charge on the 12volt battery? If anyone finds this, please let us know.
Fingers crossed, but I usually do a once a week 90 minute round trip commute to visit friends. Im confident this may be beneficial. If you own a 48v system vehicle and only drive 5 minutes down the street and back every day, I think thats where the issue may lie. The cars need to be driven for a good amount of time to allow for the systems to stay charged. We'll see if this theory is accurate in due time.
I went into workshop mode the other day in the instrument cluster and noticed there is an extended voltage display, yes.
Well, this does not seem to apply to current vehicles with the touch pads on the steering wheel. There is no "OK" button per se and I tried various alternatives without success so the procedure must be somewhat different.
