Does your Macan EV keep SoC stable when left idle for a week or longer?

Update:
My car is parked in a garage since the first week of December. It is not attached to an charger. Intial SOC: 60%
SOC as of yesterday: 60%. So no loss in nearly 6 weeks.

This is great and I can concur - mine is sitting for a second week OUTSIDE during winter -10C temps and also keeps 50% SoC just how I left it.

Do you observe increased consumption/drop in the first miles after this?

i am in the USA right now and will be back in vienna in three weeks. then i will know.
but there is allways a "higher consumption" for the first miles especially in cold/warm weather. (as it is with every ICE). the AC is running, battery has to be cooled or heated and the system has to recalibrate. consumption for the first miles is only a snapshot and is not relevant for the real range. you all should stop watching the momentary consumption !

@Petzi & @TomekGnomek, guys there's a great chance your app shows the SoC from when the car was activated for the last time and the app was used at the same time.Mine also was showing 67% stable just days ago before my friend go to the car and realized the actual wasn't what app was saying but what the car showed at the moment.From then on my app also jumped to 50% exactly as my friend reported.
However,I really hope this to not be the case for you and what you report to be the actual SoC of your cars.When you get back please confirm your car indeed kept the reported by the app SoC or not.
In 3 weeks exactly I also return home from Germany so we'll all know what happened!

i answered this several times already. the data i have been providing is current. the reading is in my case „ updated 8 hours ago“. as all the other readings i have posted in the last weeks have been current. frankly it is tiresome to post comprehensive information again and again, which is completely ignored again and again by the very same that pretend to seek answers.

No !
Even when the reading states updated 8 hours ago, it could be wrong. First hand behavior with my car.
To be sure, you MUST read the SoC in the car, it's the only reliable (for what it means with the SoC of the Macan) way to check the status of the car.
'That's @Fly4ever tried to explain...

However, I'm pretty sure that as usual, you car will be without any errors or bad behaviors, so the remaining SoC will be around 60%, if not 61%.

you are right. my (2) macan work just fine „as usual“ . as they do for the same percentage (99%?) of their other owners. same percentage as most of the better cars and machines.

And yes, it's really bad luck to be one of the few whose iPhone or Lenovo laptop, or Windows or Mercedes or BMW or Cadillac or even Rolls Royce doesn't work. But that's what warranties and guarantees are for.

Or maybe a product just isn't right for someone...

You are so adamant, that now, you even insinuate that my problems and others's are not true.
Come on... Several people have issues, more or less severe, why are you unable to accept the facts, there's no consequence for you.
14 cars actually have the 1% problem.

By the way, the readings through the App are not reliable per different owners, except you „as usual“ indeed. Even though, here, you don't know for the specific data you've provided us, because you are thousands miles from your car.
Sure, a data coming from whatever IT infrastructure (operated by Porsche...) has better reliability than the source of the data, in the car.

Even when charging my macan, the SoC could be wrong in the app.

Every time,literally every time I charge the car the SoC reported by the app stays behind what the car reports and for whatever reason keeps reporting the same lower value for a considerable amount of time up to 25-30 min. in many cases.There have been cases where the value in the car was 55% and the app was stuck at 45%.However such extreme diffeneces were always reported as data been received a while ago and not "now".But even then I clearly remember there have been some cases where the app showed fresh data which also fall behind what the car was reporting at the time, although the difference then were small like 1-2% only.

that is a misunderstanding. am sure your problems are „true“ (At least subjectively) my problem with this is that you and a few others assume that these are "universal" problems. I believe that logic is on my side when I claim that these problems are an anomaly and not the rule.

That's just not right. Just like the expectation that a car costing 100k (oh my god) must be flawless, perfect, and better than any other car in every respect.

and what is a „1% Problem“ ? are you serious ? no relevance whatsoever if the car loses a bit of soc over weeks. this has been reported for every other ev. i just wanted to give the information that i am not loosing anything. it is you and some others here that are trying to say its not true.

It's hard to debate how the % of faulty Macans is in relation to other Porsche cars and brands - we do not have the data.

It's reasonable to expect that first batch of cars (MY2024, early 2025) could have had more issues and this has been my observation with loaners I've driven. This is to be expected with any new platform regardless of the price, Taycan had it's share of problems at the beginning as well. These issues are being fixed in newer models and this risk is the price you pay for being an early adopter.

There is however one "universal" problem and this has been confirmed by two of my local dealers - the difficulty in diagnosing root causes for issues people report and the lack of support from HQ. So basically IF your car have some faults it CAN get frustrating - still, not a rule and they are getting more data so it will get better but there is some risk.

In my case for example most of the issues have been fixed but only after several attempts. There is one left that shows the above mentioned problem - the alignment going off after 500-1000kms - which the dealer states they have no clue why it happens and are attempting one fix after another.

V28.13 as I understand is a step in this direction as it improves diagnostics so this will get better.

I am not expecting flawless or perfect. Car is a machine and as any other machine it can have defects. On any new thing you have warranty. So if something goes wrong owner can just bring defective thing to the service center and they should fix it.

The issue that we are describing in this thread is that Porsche is pretending that there is no issue and are either looking at owners that are reporting this as they are imagining things or provide only excuses.

And that to me on 120k+ new car from premium brand is definitely not OK. What I would expect from such brand is to get units that are showing this behaviour back from customers, so they can be properly diagnosed to figure out why some units have this problem and other does not. And after that provide proper fix for everybody experiencing these problems.

BTW I just checked my car and after a week in garage it lost 4%. Once I opened door (interestingly car has not unlocked as I approached it which is just another random problem to the list) I saw it was adjusting SOC during boot up from 74% first to 72% and then to 70% within seconds. So that is 3.8KWh gone somewhere while battery temp stayed same...

Would you be happy if your Macan would be doing this and dealer would tell you that there is no problem even when you have photos showing this behaviour?

I do have the same issue but recently I am experiencing something new (I guess). When I start charging the car and the target is set to 80%, after some time (next morning) the app tells me that it reached the 80% and charging is done. Next time / day I get to the car it only has 75% of charge. This now happened multiple times. So either the car is not able to reach the 80% anymore (for what ever reason) or it loses 5% within some hours (4-8 hours) even though it's still plugged in. Just wanted to share this in case someone experienced the same.

This is something happened to me some times but the % drop wasn't that much it rather was around 1-2%.Now I wonder if temperatures have to do with this one way or another.It might be possible (I really don't know,just guessing,if anyone has a better knowledge please ellaborate) during the charging proccess the battery be warmed up thus the SoC shows the corresponding % of a warmed battery.At this state the % indication is most likely correct that's why the charging stops.Later,when the charging has stopped, the battery temp goes down, especially when outside air temperature (OAT) is very low.At such lower battery temps it might be possible the battery shows a SoC lower than before.Don't know,saying it again,just guessing if an "explanation" like this would be possible.

Exactly. That's why I post about how my vehicle behaves. If my car works, that's proof that this problem shouldn't normally occur.

On the other hand, many of the problems described here are quite theoretical (like loosing some SOC or not), and all other brands have similar or worse problems. So, to be honest, the “I paid so much and this and that shouldn't be happening” attitude gets on my nerves. I look at almost every test report on every EV on the market. The problems are very similar or worse for every vehicle, even the more expensive ones. But no vehicle (except the Taycan) has a better driving experience, better brakes, better steering, etc. than the Macan.

I believe that 90% of the problems described here have less to do with the Macan and more to do with the fact that there are many incompetent Porshce Centers in some countries. This is, of course, a problem that Porsche should solve. Anyone who can't repair the car should lose their accreditation as a Porsche repair shop.
