would you consider a EV that sitting on dealer about half year or almost a year
so early this mo I was shopping around. I saw many EQS AMGs that are 06 - 08/22
1st I was thinking oh I can push them for lots of discount.
but when I arrived to dealership, many of the EQS AMGs on their show room are dead with no power. not just AMG, many 580 sedan have date that is 08/22 09/22. basically that is about 9 mo sitting on the lot.
a question just popped up. EV are different than a gas car. gas car can sit there for 1-2 years without any issue but EV is different
HV battery can be low on 10% and overtime it will just drain. I dont believe dealer will check and charge it.
they might just charge it a day before someone come to check out the car.
the one AMG I really want, it is fully dead on their showroom. I been asking myself this, even if they sell it the price I ask, should I take it? maybe there will be a lot of problems I need to deal with later.
before you purchase or lease a EV, maybe consider check the build date before taking it.
edit: I didn't buy that AMG, dealer said they don't have many EQS AMG so they are not willing to take any lost. sales say maybe someone will walk in and buy with markup. yeah good luck on that

Mine is 07/22, picked up 8 weeks ago and the car is just fine. Got a killer deal
You think they literally let it sit there for 9 months? in the rain / snow and not move to wash it? Also, these things still have 12v batteries, so regardless of gas or ev, dealerships still have to charge it regardless no?

From what I've been reading it's worse with modern gas cars. Some go dead after just a couple weeks of sitting. That said, letting an EV go dead completely is really bad. They usually have a buffer just for that reason, so 0% isn't really 0%. If it's been sitting like that for a long time there's a good chance the battery capacity has significantly degraded.

no saying you are wrong but here in so cal, most the dealers I visit Bmw, Porsche and Mercedes they all have parking structure/building. There is no need for car wash nor seeing sun. Walk in will not see your car unless they pull it out for you. 5 MB dealers near me they all have over 100 EV in stock. I don’t think they are going to check and charge each of them. The one I just bought when I test drive, it only have 19% left and they charge immediately when I sign the paper. Only 26% when I sit in the car heading home. Lucky my house only 15 miles away but yeah I don’t think they would ever charge each of them. Plus they only have lv2 charger

Thing is they don't have to replace the high voltage battery under warranty until it degrades 30% or more. So if you find you're only getting 90% the advertised range because it sat dead for a few months you'll be out of luck and will just have to live with it. EV batteries typically degrade ~2% per year under normal use.
The dealer should be able to assess what the 100% capacity is. I would ask for that. On a Tesla you can pretty much do it sitting in the car. Don't know about an EQS.

I believe degrading is by % and year, mileage too. I haven’t read MB HV warranty but for Porsche it said 1st year 10000 miles should not over 10% for example. And 2nd year 20000 miles is total 15% so on and so forth.
Discount wise they offer the same ~20k off. Regardless the build date. I asked sales about that 08/22 and she just has no idea and replied you have warranty why care.

What's perhaps more stunning is all that EV inventory sitting around, but not at all surprising I guess. I would approach them on what it says in the owner's manual. They are neglecting these cars against MB's own advice. MB even states that letting the HV battery deplete can damage it. They explicitly say to keep it at between 30-50% charge for long term storage. All these cars should be hooked up to a LV2 charger with the SoC kept at between 30-50%, although it says not to leave it connected, but I'm guessing that's just referring to not leaving it connected and charge to 100%. Set the desired charging level at the charger or in the car to 30-50% so it stays there just like a 12V trickle charger.
Honestly I would walk, but I guess it depends on how long you are planning on keeping it. At this stage I'd only lease an EV anyway, so for 2-3 years you'll be fine and after that it's somebody else's problem. If the market value is higher than the residual at the end of the lease you can always trade it in to recoup the positive equity instead of just turning it in.

It might even be worth contacting MB USA and make them aware. There's clearly some training that needs to happen. But I suppose this is why I never buy off the lot anyway. EV or not. A traditional ICE doesn't particularly like sitting for months on end, either. Between the 12V battery draining, tire flat spots, moisture collecting in the engine and the oil completely draining into the oil pan leaving the rest of the engine oil dry and parts starting to fuse together, letting any car sit w/o taking proper measures is not a good idea. Mechanical parts need to move regularly, or they will start to deteriorate.
I had the dealer show me my car's VMI. 05/2022 build, but PDI at the dealer 04/2023. It sat at the port for almost a year. No real problems yet. My speculation
Port of Entry was Long Beach, so likely was stored at the Long Beach VPC (the old "Fly DC Jets" building)
MBUSA would do a better job at maintaining or refurbishing aging inventory in their possession than a franchise dealer would
Franchise dealers generally need to keep a maintenance log of inventory cars, as required by corporate

This is of course an extreme example but just as a point of reference you might like watching this video from Pine Hollow Auto Diagnostics (I really like this guy). TL;DR version: The packs that still have a charge are fine. The cells that were drained completely and left that way for a while need to be replaced.
One thing to think about with a car that has sat a long time is have there been any rodents in there building a nest. I bought a 2019 I Pace that had been on the lot for a year. A few months after I bought it, it bricked. The dealer found a substantial mouse nest built near some critical EV components, and tried to blame me for it. My garage is not really a garage--it is like a living room that gets vacuumed regularly. There's no way the mouse house was built in my garage, and I work from home so it is not sitting outside elsewhere. After some deliberation, Jaguar finally agreed to warranty the many thousand dollar repair, but it was close.

I guess in that case it depends on the area, some areas aren't prone to rodents like so.
Well, you have to be realistic about it. Most of us buying these are not planning to keep them for 5 or 10 years. If you are a typical EQS buyer you will probably keep it for 1-3yrs at most. If that is the case and you're getting a good deal, just buy it, drive it, be happy, and then trade it in when you're ready.

Just for grins and giggles tonight I was reading the legal terms of our 10 year / 155,000 mile high-voltage battery warranty. Look what's #1 on the list of things that will void it:

Unless you’re totally negligent it would be pretty tough to do that.

Define being negligent because a car sitting unattended for more that 2 weeks would not be considered negligent. At what point would a car that was properly charged for storage ie ~50% SOC reach 0%? I am assuming that you would say that the dealership in the OP is being totally negligent and it would appear that based on the post 17 they are likely violating the warranty.

You are right on the dealership being negligent.
What I meant is that it is not easy to run the battery down low enough and then have it be at 0% for 2 weeks. Even leaving a 50% charged EV for a couple months untouched is not enough to get it to 0%. It would have to be really a long extended period of time and the battery would have to be pretty low to start with.

Problem is there are so many electronics in the EQS, parasitic drain etc. I guess like a bad app on a phone affecting standby time. Thankfully you can turn on standby mode on the EQS I think that helps conserve battery but then it disables anti-theft and a couple of things such as connectivity to Mercedes Me servers for remote purposes.

Just for clarification. The electronics are powered by the 12V battery and standby mode is solely there to preserve the 12V battery if the car if left parked for an extended period. The 12V is required to actually start the car, so if it's drained the car can't be driven. Initially at least the 12V battery also didn't get charged from the high voltage battery while the car was parked. This has been a common issue with EVs and some manufacturers have updated the software so that the 12V battery charge is being maintained while the car is parked. This would eliminate the standby mode in the EQS. Sounds like MB hasn't updated this in the EQS yet and the 12V battery can still drain while the car is parked.

Joke's on them, the warranty starts when the vehicle is placed into service. If they left it dead as new inventory, there is no warranty to void!
