I did the software update and I’m actually getting some weird notices. Sometimes it says my airbag has deployed and for me to pull over safely. Other times it gives phantom crash warnings.
I took it in to service to look it up. The tech said that there is zero recorded alert messages, which normally would be recorded.
he also mentioned that it’s been a complaint of this battery software update. So more to follow I suppose… or not. I don’t know what Mercedes is going to do.

The other day, my daughter who drives this car, said she also was hearing some weird noise. But then next time she drove it went away. Now after hearing this, maybe it was related. She said it was kind of like brake grinding noise?? Is that what it sounded like for you?

Not sure if that was directed to me, but no brake grinding noise for me. For the most part I haven’t had any issues with the software update other than what I mentioned. It’s just faulty sensors going off randomly but it’s not frequent or often, it just happened to go off a couple times after software update.
no problems charging at fast chargers either, but not to insult anyone’s intelligence, even if a charger is rated for 130kwh, it may only push out 90 and that’s due to a multitude of factors. Chargepoint especially if it’s next to another station will share or distribute power.
electrify America and evgo is generally good about their stated outputs at their larger stations even if it’s somewhat busy, but a couple do distributed load even if it’s not busy.

As I've been writing for months in the forums, most problematic car I've ever had. Mercedes should have lemoned it but lemon law attorney said they found a loophole out of lemon law. 11 months 10 days left on the lease, but who;s counting?

FWIW, there is now a second battery recall involving 2022-2023 EQBs that requires a complete high voltage battery replacement.
Just received a letter from MB for our ’23 350 and they have no information about timeline for repairs.

Might just be cheaper to offer buybacks to current owners as well.
Looking at the NHTSA info, it looks like there should be additional info sent to owners around September 23.

I suspect my EQB will be headed to the car crusher when it comes off lease in July '26. Still nothing from my dealer about the first battery management software update and I would doubt the battery replaacement could be done in a timely manner, if at all.

You are going to get your max charge rate at the most discharged state, then the charge rate drop a bit at first, then decline slowly as you approach 80%. After 80%, the charge rate will decline rapidly to almost nothing as the battery approaches 100%. That last 20% may take as much or more time than charging from 20% to 80%. From a battery life and charge time perspective, you should limit your charging to 80%.
Also, you don't have to fully charge the battery when you charge. If the car is at 70% and you need to go, just do so. This especially matters if you are using the two year free charging. Just charge for 30 minutes and leave. You don't need to "fill" the tank the way you usually would at a gas station. I will admit that "fill" the battery mindset is hard to get rid of, but it will save you time (and money) when you get rid of it.
