Why does it look like your rear wheels are sticking out about 6 inches from the car?
I really do think it's a bad batch of these batteries from a parts supplier. This engine setup is running through several of MB's flagship vehicles now and I have to believe that someone there has looked into what's causing this. Can you image the damage this would do to MB if it were a wide-spread issue for all of these vehicles using this engine now?
The 48v system appears to be a growing trend in general too. I think BMW has one now as well?
Thanks to Elon Musk and the growing/rapid speed of technology advancements in batteries, I suspect we're all going to experience some growing pains with the introduction of battery power supply into the drive system of the automobile for a little while. I understand MB is investing billions now into building their own batteries and creating buildings to do it in across the globe. Think we're on the learning curve, regardless of manufacture at this point, as they catch up to Tesla and their shady lock on battery suppliers.

I think you nailed it. All E450 models (SUV's, wagons, sedans, coupes) seem to be affected, and the hunch all along has been a bad batch of batteries. If that's the case, it would be nice if MB just came out said so and did a recall.
The car was in the garage , couldn’t start and wouldn’t go into neutral to roll out hence getting the car from the garage was a big challenge. To address the issue, the rear tire was removed and a hub was installed following which the tire was put back. The hub option allowed the Mbenz technician to roll out the car from garage to the driveway and eventually the flat bed truck was able to load the vehicle.

Folks, let’s be clear where the responsibility lies for the 48V fail - MBAG. A “bad batch” of batteries from “suppliers” is the responsibility of MBAG. Carmakers specify detailed requirements, including test/validation and manufacturing process, to their suppliers.
Roadside attached the front tow hook and the car went easily into Neural and he was able to load it up the truck without problems.
Called the Front Service desk said no loaners till Nov 2nd, however my sales guy was able to arrange one.
Drove in the pickup to the dealership and have a GLB now.
While talking to the service advisor, he said they have seen a few of these and if it is 48V, then it will take a day to order it as there is some special order process to get a new battery.
Will update once I know more.
Where did you get the mug flap? I cant fine them anywhere. Thank you
2020 GLS580 with 13K miles purchased a year ago it won't start after 2 hours stop at a mall. All the warning sign were on
Called MB SOS after 20 min wait they called the toll truck (2 hr wait) for us to tow to the nearest dealer.
After waiting about 40 minutes the car started fine with no issue.
Very disappointed and lost confidence in my beautiful Emerald Green Car
We use this vehicle to tow our Airstream trailer to remote places and now we are very apprehensive about driving it out of town
Please note there was no sign for 24V battery.
Plan to call my dealer Monday and find out the potential cause for this event and what are my options

It's actually possible to get the car in neutral with a dead 48 volt battery (or at least in worked for me on two occasions with two different Roadside guys). I couldn't do it, but each Roadside guy kept moving the shifter back and forth until somehow neutral engaged. It took some perseverance. The trick then is not opening the door, which automatically causes the transmission to revert to park. So the person who managed to get the car in neutral had to stay inside while a second person operated the winch to get it on the flatbed.
My 2020 GLS580 would not start and after waiting for 30 to 45 min it started.
It happened again couple of days ago, after wailing for 30 minutes it started fine
To day I took it to dealership, they think it is starter generator or may be 24 volt battery.
Will post the outcome
"
The saga of not starting 2020 GLS580 continue. As per my previous post my car is still at the dealership being diagnosed.
One of the service advisor send me following e-mail after finding out the non start issue
" It’s happening more often now to people who don’t drive and drive only locally. At times it is good to leave the engine running for 30 minutes or drive for 30 minutes to recharge the battery. If you haven’t since then I would recommend it to avoid that happening again."
I HAVE BEEN DRIVING THIS CAR LOT MORE THAN 30 MILES A DAY
CAN YOU BELIEVE IT, A FLAG SHIP MERCEDES SUV HAS THIS TYPE OF ISSUE. I SHOULD HAVE BOUGHT A HONDA. THIS IS MY 7TH MERCEDES. I HAD HUNDRED OF THOUSAND MILES ON SOME OF THEM WITH NO PROBLEM.
Keep you posted when I get it back

There is absolutely no way on earth that is an accurate statement for the cause, and quite frankly a very stupid and reckless thing for any MB employee to even remotely suggest. Any representative that suggests this to be the cure, or used this as an excuse to get out of having to do the work to fix it correctly, needs to be fired.
Can you imagine a scenario where someone has an accident and says they wouldn’t of been there in the first place if they didn’t need to drive their Mercedes Benz 30 miles a day so it won’t just shut off on its own because of a dead battery? Just stupid.
What you experienced, is exactly why I never take mine to any dealership for service, even if the service is free. I’d rather pay $300 knowing it’s done right and is perfect the first time via my indi. Only if a warranty claim exists (which is clearly the case here for you) will I ever engage a dealership. And even that it hit/miss! Mine has to go back in for a second time over the drivers side window binding and popping when going up/down. Last time I got the “could not duplicate”. This time, I come fully loaded with video evidence.
The loaner I had last time (GLB), was a rolling ashtray that stunk so bad I actually cleaned it for them….and then emptied an entire can of Lysol inside of it. Soaked it down with that stuff because I was so pissed off they’d give me a loaner in that condition while my “S Class of SUV” was being repaired.
I HATE MERCEDES BENZ DEALERSHIPS. Out of ALL the brands I’ve owned since 1988, they have been the absolute worst in my entire life when it comes to service. Hands down, not even a debate. I’ve been through 4 of them in 3 states. Not once have I had “best or nothing” experiences. In fact, I can’t think of a time when I took either car (I have two) into a Benz dealership for service that didn’t require me to bring it back again to try again. Simple stuff like alignments, brakes, even putting 2 inches of 3M tape on the end of the deck spoiler on my E class (which somehow resulted in scratches all over my trunk that are still there 4 years later). They are just pure garbage in my book.
love the cars, just can’t stand the network they dispense them through..

That was the first thing someone from my dealership told me when my 2021 E450 wagon wouldn't start after about 200 miles ("this could happen if you're making too many short trips"). As it turned out, it was a defective 48 volt battery in my case. I understand that if a car is sitting idle for weeks or months, there might be some issues in starting it, which is why some people on this board have suggested using a trickle charger when the the car is idle for a long time. But the suggestion that you need to run it for 30 minutes every day seems ridiculous to me. These are supposedly the finest automotive engineers in the world and they can't produce an $80,000+ car that will reliably start even after being idle for a couple of weeks really strains credibility.
I have a 21 450 with about 6300 miles and had this on my dash when I tried to start. Is this the same issue everyone is having? What’s worse is I had my two kids in car seats ready to go to school and now I’m waiting for roadside…
Note, mine doesn’t say anything about 48v battery…

I'm afraid it seems like the same condition. My notice also referenced the 12v battery; however, it was in fact the 48v battery that had to be replaced. Sorry for your trouble. Please keep us posted on your diagnosis and fix.
I agree. It sound like there's a flatbed in your future. Hopefully your Roadside person knows how to get the car in neutral so it can be winched up on the flatbed. I believe it's a matter of toggling the shifter back and forth until he gets lucky. Then, someone will have to remain in the car as it's being winched because opening the door will cause the car to go back in park.

4 hours later to get a tow! What a nightmare since 7:30am and I’m in North Broward County. MBUSA was shocked it took so long as that process had failures with them dispatching Jack rabbit to jump and they never showed. Tow truck Driver tried to jump and no luck. He had no issue going into N though I believe the battery pack was still connected.
Another member posted that he thought the tech had the charger attached when he got the car into neutral. I wasn’t paying enough attention so I don’t know if that was the case with my car, even though I went through it twice. Sorry you have to go through this. Possibly you’ll only need a software patch, but also possible you’ll need a new 48v as well. Then the question is how long before they can get the new 48v.😩
(Price is Right theme song playing in background) Come on down your the lucky winner for a new 48v battery! Just got the call they had to order it and it will be a couple days to come in. Hopefully it’s accurate and not weeks like I saw someone post here?
Even though this was really a disaster experience I’m so lucky it didn’t occur on my 1800 mile road trip I’m making in a couple weeks.

Welcome to the club nobody wants to belong to. That's the right attitude for sure: better now than in the middle of a road trip!

I’m thinking recall is in order here now. MB can’t have vehicles roaming around out there that are just going dead like this. There is OBVIOUSLY a bad batch of batteries in their parts bin, and enough instances here to document an emerging trend. Maybe it’s time to alert the NTSB for some pressure on MB to start replacing these batteries before someone gets hurt…

Members have been encouraged to report these issues to the NHTSA and a number of us already have. While I was fortunate enough to have both of my battery failures occur at home, they could have occurred anywhere -- in the passing lane of a highway or in the dead of winter in the middle of nowhere. This is a known problem and it's only a matter of time before inconvenience escalates to a serious safety issue.
How long has it taken anyone to receive the new 48v battery. My update today is they have no ETA! Which is not encouraging and I have my big road trip in about 2 weeks!
Anything I can do in regards to contacting someone to ensure it’s sent asap to them?
