Failure of the high voltage battery in my Mercedes-Benz EQB300 4 matic
The vehicle suffered a high-voltage battery failure on July , 2025, leaving me and my family completely stranded in the middle of our vacation. This incident not only disrupted our plans but caused a domino effect of complications in both my professional and personal life.
What makes this situation even more unacceptable is the complete lack of communication, support, and accountability from Mercedes. Since reporting the issue, I have received no meaningful updates, no timeline for resolution, and no assistance whatsoever. I have been left on my own to deal with the consequences of a serious technical failure in a premium vehicle, which I trusted for its quality and reliability.
Mercedes continued silence speaks volumes. It reflects not only a disregard for all customers but also a deeply troubling corporate culture—one where those entrusted with upholding the brand instead contribute to the erosion of its reputation and the trust of the very people who once believed in it.
At this point they're just ignoring an emais.To treat someone as if they are insignificant or undeserving of even a basic response is, quite frankly, shameful.
The complete lack of response, transparency, and action over this prolonged period demonstrates a level of customer neglect that is truly shameful for a brand of Mercedes-Benz’s reputation. This prolonged inaction is unacceptable, unprofessional, and completely contrary to the standards expected from a premium manufacturer.
From where I stand, it appears that the only time customers receive genuine attention is when they walk in with the intent to spend money. Once a sale is made and issues arise, they are left to deal with problems on their own. This attitude speaks volumes about the current state of your professional culture, and frankly, it reflects poorly on the brand's values.
This experience has significantly damaged my perception of Mercedes-Benz. I expected better—not just in product quality, but in how you treat your customers. Sadly, I now find myself seriously reconsidering any future relationship with your brand.
For more than 40 days I have been waiting for a meaningful update on my case – and nothing has been provided. To leave a customer without information for such a prolonged period is unacceptable, and it demonstrates a lack of empathy and understanding, despite your claims to value customers.
Is this truly the best Mercedes-Benz can offer? Your motto “The Best or Nothing” seems to have turned into “Forget About Us.”
I am certain that if anyone on your team were in my position – waiting 40 days without a car, without a replacement vehicle, without even a clear update – they would find this situation just as unacceptable.
This lack of communication is extremely disappointing and unacceptable for a company of Mercedes-Benz’s reputation. Instead of transparency and responsibility, I have only been given repeated apologies without real solutions or updates. Such prolonged silence shows not only poor customer service, but also a lack of respect for your customers.
When in the history of the automotive era has Mercedes-Benz fallen so low — humiliated and outperformed by nearly all competitors?
It is a bleak picture, and a shameful, shameful reality.

TLDR.
Are you asking / looking for help with your battery or battery issue, or are you just venting?
If Mercedes is being unresponsive, then find an attorney who can light a fire under corporates' ****. Though, I suspect there is more to this story than Mercedes just flat out ignoring you. What is the dealer the car is at, saying?

This is not “venting” — this is a serious consumer issueThere is no meaningful response, repair, replacement, or timeline from either the dealer (Silver Star Motors, Bulgaria) or Mercedes-Benz AG. and yes i have already contacted the dealer repeatedly, but the responses have been completely inadequate: No clear status updates on whether the battery is removed or prepared for installation/No replacement vehicle or compensation /No official written explanation or timeframe for repair.This lack of action constitutes a breach of warranty and consumer rights under Bulgarian law (ЗЗП) and EU Directive 2019/771.

If you're looking for help with possible diagnosis, or ideas to bring to your dealer to look at, then by all means, tell us what was already tried on your car, what the symptoms are, and what the dealer thinks is wrong. So far you've just ranted about your experience with Mercedes.
Like I said, I suspect there is more to this story than you're telling us here. You know the saying, "There are three sides to a story. Your side, his side, and the truth".

I do not intend to attack anyone; I am simply sharing my personal experience. I believe the forum should be a place for exchanging information and different perspectives so that everyone can be better informed.
I understand that not everyone has faced such issues and I respect that, but it is also important to acknowledge the other side of reality. My intention is only to share my personal truth, not to create conflict.
I would like to clarify that my intention was never to argue, but simply to share my personal experience. I believe a forum should allow different perspectives, as this exchange of information can be useful to others. I respect that not everyone has the same issues, and I only wished to present my own point of view. This is not a dispute, nor do I seek to create one.

No one's trying to create a conflict or argue, don't get your panties moist. What I'm saying, is that if you're ranting, that's fine. Maybe you're posting here oping some MB employee sees the post and does something. Hell, I don't know, man!
Usually, when someone posts a post, (rant or otherwise), the person is looking for more insight, as to what could be done, not just rant on about how Mercedes is culpable for his inconveniences because the freaking car broke down and how a "premium brad" is screwing him over. Again, I suspect there is more to this story that you're not sharing, and I suppose it's you prerogative to not expound on that. I don't know EuroCuck laws and directives, but like I said in my first reply, maybe it's time you hired an attorney if MB corporate is blowing you off.
But if you actually want some help, then you really ought to give us more info on what / when / how / etc. that your car exhibited prior to the issue(s). If you don't... well, then good luck and may the Mercedes Star shine on your day... or some such thing.
