Got in, pushed button. The engine is soo quiet I'm not 100% sure if it started but i saw the rpms fluctuate a few times. Then it went back to 0. The Mercedes me app says the battery is partially charged. I'm not sure if that means there's not enough juice to start the car or if there's some type of mechanical issues. Sucks because it's a holiday weekend.

I also tried a remote start and the app said the engine was running when it wasn't.

Tried again a few minutes later. Car ran for a few seconds then died.

Sorry to hear that you are facing this issue, so you are saying there are no actual error messages on the dash, is that correct? That is strange then because if the app reports the 12V battery being partially charged, it should also show on the vehicle. Hopefully it isn't a 48V battery issue.

@ColeBlooded is this related to the 48V systems? Try reading the W213 E-Class and V167/X167 GLE/GLS sections of the site to see if what you are experiencing is similar to what has been posted for those vehicles.

Sorry to hear of this, hopefully not a 48v issue and dealer can quick fix. Keep us posted.

ColeBlooded

I can't recall what message popped up but it wasn't the 48v battery message. From what I've read, people who've had the 48v problem where still able to start and drive the car.

I'm gonna get up early and call roadside assistance and have it towed early as possible.

W205C43PFL

Hmmm, keep us posted but because the 48V battery does power the electrical starter, the AC compressor and the electric water pump, it is necessary to be operational for the car to function. In short, if that malfunctions the car wouldn't be able to start so from the symptoms you are describing, it maybe in fact is the 48V battery. However, I don't think that battery defect should be present on the W223.

Uggh, that's gut wrenching on such a new car! GL!

SW20S

Ugh! What wound up happening?

W205C43PFL

​​​​​​​Ugh is right! and worse is op's dealership "lost" his car until later that day, the dealership kept saying they couldn't find the car once it was towed there.

So ridiculous!

hyperion667

What in the actual fawk!

ColeBlooded

I think it was the 3rd or 4th phone call when I asked to speak to the service manager when they finally acted like they cared where my car was. They found it. Service advisor says they've been backed up, and says he'll have updates on the diagnosis by this evening.

I didn't wanna get too belligerent while they have possession of my car but that was pretty ridiculous and I feel like if i didn't keep calling, nothing would've happened.

SW20S

They should have had the service manager himself out there waiting to take possession of the car. Crazy.

ColeBlooded

Agreed. As soon as the tow truck driver left my house I called the dealer for a heads up. They tell me there's no need and the service advisor will call me when it arrives.

I'll make my 1 star reviews and talk to the service manager when this is all done. Possibly before. They're gonna be tired of me.

SW20S

And this is such a missed opportunity for the dealer. As someone who is in a customer service business, it makes me cringe. Huge opportunity to turn a very negative experience for you into an opportunity to shine for them.

As much as you paid for that car and as much as a Mercedes dealer commands for service, they should pretend to give a **** about you.

W205C43PFL

Exactly, the sad part is as you stated... they didn't even pretend to care let alone actually caring.

ColeBlooded

SW20S

So, so frustrating...

W205C43PFL

Thanks for updating us on your vehicle's status. Your SA gave you a pretty vague update though, I was hoping they at least tell you what they tried/didn't try and what error codes the car returned, it just seems like they put all the responsibility back to MB corporate. Either way, hopefully they give you a satisfactory response soon.

SW20S

They have no clue whats wrong

ColeBlooded

Agreed. I've called the dealer 3 times today i believe. I always get a voicemail. Terrible customer service.

Are they owned by DTLA Motors, same as Porsche-Audi-VW? I had amazing customer service with Porsche when I had my 911. I’d drive past Beverly Hills Porsche service to go to them.

Sorry you are having such bad luck with their customer service. I’ve had decent luck with Simonson and very good luck with Beverly Hills Mercedes, FYI.

Best of luck to you!

ColeBlooded

Yes DTLA. Beverly hills and DTLA are almost the same distance from home so I'll definitely try there next time.

If nothing else, their customer service lounge area is really nice. They have a barista serving drinks and fresh fruit, bagels, etc. Well, they did pre Covid. Anyway, they always took care of my wife’s E350 cabriolet very well. Then we moved to the Marina and have been going to Simonson ever since for both my S550 and her ( new to her ) SLC. Simonson may not get it right the first time, every time, but they will keep trying until they do. They don’t give up.
