So stopped at a fast food restaurant to pick up some to-go lunch, and when I came back out my 2022 GLE580 would not start. Every light on the dash board lit up, and Bluetooth worked, but the 'start' button had no affect. Called the MB hotline and they sent out a tow truck to get me to the dealer. After a couple of hours, when the truck arrived the driver was going to jump it, but it actually started up without the jump! Very scary. Now don't trust the car... (sigh). the dealership has it and will look for codes, and if no code, will work with the electrical system.
Anyone else have a similar experience?

This happens to me occasionally. I let it sit for15-20 minutes and it starts right up.

Thanks, J_house, still makes me nervous though. First time since I got it that anything like this happened. Will see what the dealer service team can find out.

Just got a call that the dealership detected something in the software related to the 48v battery. They are applying an update that takes 8 hours (!). Should get it back tomorrow PM.

wildta

Please do post the work order and notes for the rest of us once you get it back.

tomb73

Can do...

chassis

Sorry to hear and hope for a fast and acceptable resolution.

Three model years later and MB still hasn’t solved the 48V issues. Stay away from MB 48V systems, far away.

They did identify an error condition with the 48V battery. So, here's the notes from the service invoice, apparently corrected with a software update, though they did remove the rear seats and check out the cables and connections as well.

Give it a break bud. The Mercedes battery issues (cars produced last 2 years) may very well be less than most others.

Take a peek at the Porsche Taycan issues and you can expand your griping. Porsche flew a Tech into my Dealer last week to deal with several ongoing Taycan issues that they couldn’t resolve remotely. The first boat fire (Felicity Ace)…likely caused by an EV had VAG EV’s.
Personally I’d rather have a battery controller software issue like this one than an exploding EV battery fire in my garage or anywhere else. All brands seem to be having EV issues of some kind. For some reason you don’t see the pictures of a Tesla on fire anymore…maybe not politically correct with the Woke crowd.
Now another ship (Fremantle Highway) burned up with BMW and Mercedes cars onboard. The EV fire killed one as an EV exploded.
Spontaneous combustion of EV’s parked! Russian Roulette, IMO.
I don’t recall one Mercedes 48 volt EV issue that burned up the vehicle….just saying!

It sounds like they did a very thorough job of investigation, and you should probably be fine going forward.

Yes there's a February '23 recall, link here - https://static.nhtsa.gov/odi/tsbs/20...32318-0001.pdf 58,540 cars, I didn't know about it either.

Symptoms -It's a Battery Management System update. My RV forum members have many threads about lithium battery Management systems and firmware updates.

I doubt that it damaged your battery, because it was disconnected by the BMS. That's why it wouldn't start.

BenjaminKohl

what the hell does any of this have to do with “woke”, whatever you think that means?

Ron.s

If you don’t understand the term “Woke” I can’t help you. You might Google Greta Thunberg for an example…Or NY Representative AOC and the “Squad”.

There is an ongoing Political and Media push to blame everything on “Climate Change” since “Global Warming” didn’t pass muster. The answer is mandating EV’s. Any bad news about EV’s seems to no longer be newsworthy.
The fact that EV’s are having serious issues doesn’t seem newsworthy anymore isn’t the reason, IMO. It just doesn’t fit the narrative! How much coverage did anyone see on National news media like CBS, NBC or ABC covering the burning Fremantle Highway ship? I could be wrong, but IMO it’s not woke or PC to cover negative news about EV’s in todays world.

wildta

Please let us not ruin every thread with divisive political banter, that's why the moderators created a sub forum for that. I have a 580 and would like this thread to stay on topic.

mikapen

Unfortunately, the political climate is a driving force in the auto industry.

Not recognizing the ESG agenda, or the pressure for politicians to embrace it, would be avoiding what is probably the biggest factor in what we'll be driving in a few years.
It's an important topic that even affects 580's.

My opinion about ESG (another term for "Woke) is shared by many (most in the USA, BTW), so "not talking about it" is probably Ostrich bait. (Yes I'd call myself an Environmentalist.)

It's not Banter, it's a discussion. One can add to it or ignore it. No reason for another thread-killing attack.
I don't know if I've ever seen a thread that didn't have "thread drift."

I think we'll be OK. The thread is still alive, waiting for feedback from others.

If you read the ticket carefully, the only thing of substance they did was update the software and reset the code. That’s MB’s universal solution to a lot of problems and it’s essentially MB crossing their fingers and hoping the problem doesn’t come back…

tomb73

What the service tech said was they did detect an error (BATTERY DETECTS AN ABNORMALITY WHEN THEN CAUSES 48V BATT TO DISCONNECT ITSELF) which then called out an update to the software. Agree that it does not give in depth detail, but he did feel that it was specific enough to lead them to that action.

We also chatted about the 48v battery, and the push for electronic vehicles, and he was a bit concerned about the amount of software in them, and that they had already seen indications there were going to be problems with it... About half of the inventory on the lot was EV's.

mikapen

I read it differently, with a lot of unpaid diagnostic time spent taking the interior apart, verifying no faults.

Those are the steps that a do-nothing shop skips.

I would go to that shop in a heartbeat.

Ron.s

Divisive? Every thread? Give me a break. That’s your opinion so I assume you don’t agree with me & that’s OK.
What I posted is a fact, maybe not on topic…except that even the smaller Lithium batteries in the GLE pack a lot of fire power, not far from the fuel tank.

Frenetic

Ron is a troll. Just like Mikapen. These geniuses diagnosed my car and said everything is ok with the piece of crap without ever stepping within 100 miles of it, let alone even seeing it person. That is all you need to know about these individuals.

wildta

My apologies @Ron.s. By "every thread," I meant every time politics are mentioned, the thread goes on a long off-topic diatribe. It just irks me.

On the contrary, I appreciate many of your posts and I actually agree with you, in part, about EV batteries and fires. I disagree, for now, that an EV caused the fire on the recent car-carrying ship because I don't think they have any evidence of it yet. However, I fully agree that lithium batteries are a major problem when they catch fire and made the fire much more difficult to contain on that ship, and many other car-carrying ships in recent history. I'm not against the world going EV but I'm not ready yet, I like my V8TT and the 48v system within it (reduced turbo lag is nice). In the meantime, I'll accept @mikapen's advice and just read thru the noise. 🤐

mikapen

False statement.

We asked clarifying questions, as did many others.

Ours were on point, and you were unable to answer the questions. The simplest ones.
Embarrassed, you attacked everybody who tried to help. How many threads did you kill?

You fabricated your "many" dealer experiences. Read your comments in the threads again to understand. Thank you. 🙂

You ended up arguing with yourself several times, mistaking your own posts for ours. You threatened me in a PM. Angry guy.
You must have begun pounding your keyboard before you read the posts.
