As usual…you are stating your opinion backed up by phone calls trying to prove your previous brash statement …about something that won’t ever affect you. You are on record that you intend to sell your car before the warranty expires. The fact is that the battery is not yet packaged for retail sales and that won’t occur until closer to the time that the OEM warranty expires. No one has any facts about a future battery warranty.
You also seem to ignore inconvenient truths. There will almost certainly be some type of a warranty on replacement 48 volt batteries. Every new auto part has some warranty even many rebuilt components have them. There is also US legislation (Magnussen-Moss) that covers express and implied warranty for products sold in the US. You can keep stating your opinion repeatedly but repetition doesn’t make it any more factual.
And Mikapen and everyone else isn’t? Ron, I hate to burst your bubble but everything that is said here is precisely what you’re accusing me of saying and/or doing. I feel like you’re part of my fan club now, obsessed with me. But feel free to continue.
And TexAg, thanks for sharing that. That obviously doesn’t jive with what MBUSA told me.

You might actually read what I said and respond factually. Obviously you have an “Axe to grind” and aren’t interested in reality.
You might study up a little more on warranties if you want to make accurate assumptions. There is a complex Federal regulation on warranty that goes beyond expressly written warranties and is one reason that consumer products are written with a warranty today. Many states have a their own warranty laws and the most severe ones in the US become the baseline. California usually leads as they do with CARB for emissions.
You made a statement that there is “no warranty on the 48 volt, zero, zilch, nada” and can’t back it up with facts. Keep calling people if it makes you feel good. Until you can show a retail sale of the product that states there is no warranty then you are wasting everyone’s time by repeatedly making that irresponsible statement.
Hopefully you are only on this Forum during lunch or breaks and not during Costco work hours.
Ron, I backed it up based on what I was told by MBUSA. None of the warranty documentation outlined those batteries except for what TexAG shown, which does specifically reference a warranty for that battery. I don’t think any reasonable person would assume the dealer and MBUSA were incorrect, would you? I guess the lesson here is don’t necessarily trust the dealer or the MBUSA rep. But I agree, that’s why I kept asking if anyone showed any actually documentation and Tex did just that.

Why do you even care?
Calling MB Customer Service for something new and not yet sold is akin to calling IRS for tax advice. Most of us know better. They are PR oriented although some have more knowledge than others.
There will always be a warranty statement for a product like the EV battery sold to a consumer. It’s highly unlikely that it will state there is no warranty (perfectly legal) because of the existing laws on implied warranty. No warranty at all would be an Attorneys “dream come true” for an expensive vehicle with Class Action potential. Mercedes isn’t stupid and it’s always possible that they try to be fair.
A reasonable business decision would be to at least match the existing 12 volt battery warranties.

Dunno why you continue to miss the attachment to post #54.
It is Mercedes' ACTUAL replacement parts warranty. Batteries, including the 48v battery, are warrantied for 48 months, IF they are installed by a Mercedes shop. Then the warranty includes installation, calibration, all the rest, free. No pro rata reduction, 100% for 48 months.
For your reading pleasure, below.
It's ATTACHED. The battery portion is at the end, and specific.
"2.2 Any replacement battery purchased on or after August 1, 2000 at total customer expense is covered
for a warranty period of 24 months, unlimited mileage from the date of purchase. Warrantable repairs
will be made at no charge for parts and labor when performed at an authorized Mercedes-Benz Center
(Passenger Car, Light Truck or Sprinter / Commercial Vehicle, as applicable)."
Since those batteries are covered by other emissions and new car warranties, there would be no need to purchase a battery for many years. Unless you void your warranty, which is also described.
After browsing the parts department link that Tex provided, even the brake pads have a warranty. I wonder if you can buy a set, track the car to hell and back and wear them down to the sensors within 12 months, and redeem that warranty.
In fact, every part has a 12 month warranty, regardless of the fact if it’s a wear item. I wonder if most consumers don’t realize this, and allow dealerships (like mine that had no idea) to fleece them unnecessarily.

Like any other warranty that exists in the world... there will be a clause that excludes damage from wear and tear.

You answered your own question, this topic is about the 48V battery.
I have never even owned a Mercedes (or any brand other than my current Subaru..) so I don't think I'm particularly biased, but this entire GLE forum section keeps getting derailed by two distinct groups. One group who loves MB and one group who hates MB, and its getting really tiring.
I hope the OP hasn't been scared off by all this back and forth bickering, I'd like to hear an update eventually.
Let's talk 48v batteries.
Mercedes batteries in particular. Here's some background about their fits-and-starts battery saga.
A decade or so ago, Mercedes (primarily, along with BMW and Bosch) formed a Joint Venture with Grohmann Engineering GmbH, as their battery and production partner. They were said to be leading the Industry in battery innovation and, especially, production techniques.
Later, Tesla became a client of Grohmann because the tech was superior to Tesla's.
Then Tesla, with all it's $Billion$, bought Grohmann and retained the 1963 founder, Klaus Grohmann as boss. In 2016-17, right in the thick of "EVs Rising."
So far, so good.
But then Musk declared that the new firm, now named "Tesla Grohmann Automation GmbH," would not only refuse to supply M-B and BMW with the advanced proprietary batteries, but also their own Production Facilities, dishonoring the contracts in place.
Klaus Grohmann took exception to breaking the contracts, (implied or not, I can't find out), and was summarily fired by Tesla. Tesla said "mutually agreed," but Grohmann was legally silenced and would only say, "I definitely did not depart because I had lost interest in working."
Whatever the case, Mercedes and BMW had to re-start their battery and battery production efforts anew, including building a new plant.
Loss of IP and plant-building moved Mercedes from a First Mover status to Catch-up.
Yes, I think Mercedes (and BMW. Bosch and Intel) have somebody other than themselves for falling behind.
Here are some links for you to read. And links within. Earlier news stories were much more vindictive against Musk, but they're not showing im my search right now. I wouldn't be surprised if M-B sued Musk. Like Twitter owners this month, alas.
M-B is on to another battery concept, with advanced cooling and recharge, as seen on the new AMG Partial EV offerings.
So it could be GM with their Ultium batteries and M-B's new tech puts those manufacturers back in the lead.
But who knows about the future of batteries, or even Energy, in the future.
After reading the parts and service warranty, anyone can use it to replace the 48-volt battery because it’s not explicitly excluded or stated. All of my relatives and siblings are attorneys and they agree you can take Mercedes to task with the 48-volt or EV battery.
While this thread was about battery failures, it often turns into discussions about written warranties.
Here's a warranty that might solve everybody's concerns, as written.
Now, "if only" Mercedes would adopt it, maybe the World would be Ok.
It's s USB C cable from Amazon. The "connection" is that I bought it for my 167.🙂

It seems that you have invented the issue with the 48 volt battery warranty. There won’t be any out of warranty for 6 months so there is no problem except for a guy with 3 1/2 years left on his drumming up conjecture and opinions of his own making. The sky isn’t falling yet!
This is showing on the website for Mercedes dealers. (I checked a dealer in Florida, one in Texas, and one in MD). Notice the warranty for the Hybrid/Electric system components.

Thanks for that. It's what others have been posting about the original equipment warranty on new cars.
There seems to be confusion in this thread between OE batteries and replacements that would be needed after the OE warranty expires.
To clarify, if you are beyond 96 months / 100,000 miles , when you buy a replacement and have installed in a M-B shop, parts and labor coverage is covered 100% by the parts warranty.
Until then it's covered by the car warranty, as you posted.
Mercedes would be wise to clean up all of the warranty disclosures. What’s written in the actual warranty disclosure doesn’t match what’s stated on websites and elsewhere. Moreover, you‘ll get different answers depending on who you ask (e.g., dealership and MBUSA). There’s a lot of discrepancies and a lack of full disclosure both in the original manufacturer’s warranty and any new purchased part.
I know a lot of this technology is new (I.e., mild hybrids, etc.), but to put out a product without clearly thinking about and documenting everything leaves a lot to be desired and says a lot about what’s going on behind the scenes.

That’s interesting. Either:
1. The ad is incorrect, it is 8 yrs/80k mikes as required by Fed Law
2. Those states require emission components be warranted longer than the Feds — to 100k miles
3. The Fed Law has changed, it’s now 8yrs/100k miles.
Anyone Know for sure? I’m thinking AutoNation screwed up.

Here's a screenshot of the Mercedes 2020 warranty book.
To reduce the confusion here, it's important to know that the 48v system is not considered a "High Voltage" system. So the Plug in Hybrid line doesn't apply.
Since it's under 72v (the danger to First Responder threshold), it's considered "Low Voltage."

Reason: 72v not 60v
Makes you wonder if the warranty statement found on the parts website that Tex linked for replacement parts is worth a damn. All it takes is one lawsuit to fix this.
This appears to be one of the best warrantied batteries in a Mercedes. Regular 12V car batteries, wether AGM or Lithium are not afforded such generous coverage, yet here this is being discussed this as it would be a negative.
