Battery recall for '22-'23 - Class action?
Safety recall 2025040005 regarding Battery Management Software. By now many of the '22, '23 EQB owners have received the safety recall. While warning about the possibility of a short in the high power battery leading to fire it provides a software remedy. The remedy not only degrades the driving range (which was one of the worst on the EV market anyway) by 11% at 100k miles but also increases the charging time which was another sore issue.
Within 2 years from manufacturing MB is coming with this recall that alters significantly the most important performance specifications that were considered in purchasing this vehicle.
What are the opinions of other owners about this?
Are there any law profession owners that can weigh in and advise whether a legal action can force MB to buy back or to offer some compensation considering this gross misrepresentation?

I agree that this seems to be a class action issue. Materially changing the specifications of the vehicle through a recall seems completely dishonest. Would I have purchased the car had I known of the impact of these battery issues? - no way. The projected range was just at the acceptable range when i purchased the car. With the recall "fix" that Mercedes has offered, it is just not the same car. I would join a class action effort for sure.

FWIW, here's the exact verbiage from the recall letter for those interested:
Personally, I'm looking forward to our leased EQB going away.
Additional Information
This software update will not impact the charging time when using AC charging (i.e., home wallbox or public AC charging stations), nor will it impact your vehicle's acceleration, rated power output, or energy consumption. The software update will gradually reduce the vehicle's driving range as the vehicle mileage accumulates over time (e.g., the possible driving range reduction is calculated as 5% from approximately 31,000 mi, 8% from approximately 62,000 mi, and 11% from approximately 100,000 mi). Moreover, the software update might impact the charging time when using DC fast charging stations (1).
(1) For example: If the vehicle were to charge at a 100 kW DC fast charging station from 10-80% SOC, the charging time may increase by 10 to 15 minutes, depending on the vehicle's mileage and battery condition. Please note that, as stated in your owner's manual, a variety of factors might also affect the range and charging.

I got my letter yesterday. I'm surprised that MB thought this was an acceptable solution. A range artificially heading south as a battery range will already be heading south with age and miles is not insignificant. Any lawyers in the group who could advise on litigation?

The remedy for those of us who leased is suck it up until the end of the lease. For those who purchased, sell it at a huge loss or keep it and suck it up. Even if a class could be put together, the litigation would take years and the likelihood of success is minimal. And virtually every EV lease is under water, so we have little choice but to ride it out or roll a ton of money in negative equity into another lease or purchase. We can only take some form of satisfaction in knowing that when the worthless lease returns come back to MB, they will be stuck with the cars. And some used car purchaser will get a very good deal.

FWIW, we had the recall update performed today. It was a very quick procedure, apparently, and had I known that I probably would have just waited rather than making two trips with a loaner.

I'll update when I take the car for B service the end of June.
But the car is starting to feel sluggish in reverse, just like it did before the rear motor failed. Maybe if I have another rear motor failure and it is in the shop another 3 weeks, Mercedes will finally agree to buy it back.
I did find out that when these highly-depreciated EVs come back on lease, MB will auction them to recover whatever they can.

Brought car to dealer for B service, noisy AC fan and software update. Oh, and there was actually a recall to install the NACS sticker.
Software update was not performed. Service invoice stated "Update not performed. Customer will return when software is more stable."
And the A/C noise was documented in a tech bulletin where it indicated that debris could get into blower motor. So had to disassemble blower motor housing, clean out and install two gaskets to prevent leaves and other debris from getting into fan housing.
But after reading that some of you have successfully had the update installed, very weird to hear "...when software more stable." Service Advisor had nothing to say other than that the software was not stable.
Yet another adventure in EQB300 land, as I've indicated... the worst car I've ever had. Oh, and lease is $14-15K under water so no point in getting out of lease early and rolling that much negative equity into another lease.

The EQB has variable limiting of the charge speed as a function of the battery charge level. At low levels 10-30% it will charge with ~90 kW, 50-70% ~50 kW, 80-90% ~20 kW. What was you battery level when you were reading 35 kW charge speed?

Charging from 50% hit 65kwh. It's about right I think. I usually only get 100 kWh when it's around 20%.

Interesting that some of you report the update was performed but my dealer said "customer to return when update is stable." No more details other than service advisor said update is not stable. I suspect it is actually related to the ongoing issues with my car which Mercedes refuses to acknowledge.

"Update corrupt"

Maybe MB realizes that this fix is inappropriate and is looking for another solution?

I contact MB corporate to say the 'fix' is disappointing. I never heard back. I don't think their solution is fair to us, even if they can push on a non-corrupted software patch. It wouldn't hurt for you all to contact MB corporate as well.

Unless we have a lawyer sending an official letter of intent to MB, calling is as useful as an ashtray on a motorcycle. Sorry for the sarcasm.

MB Corporate never responds. Their entire model is to compel all communication between customer and dealer. Dealer then tries to engage MBUSA, many times unsuccessfully. Dealers are as frustrated with MB Corporate as end users. And today I read that BMW is recalling some 70,000 2022-2024 EV's over battery management issues. A big dfference, though, is that this can either be done at dealer or OTA.

I think it was the charger, because charging afterwards at another charger and we got 70kwh.
