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

Same here, and some times it's close to 2% per day, no Dashcam, no nothing.
COuld you check the temp of the battery, the day before and the day you check the battery SoC?
in my car, this battery temp seems to remain high, for instance, the battery stands at 21 degrees C after 4 days in an underground parking at 18 degrees C.
To me, the car doesnt go in sleep, and keeps the battery under some unknown activity.

As part of all this SoC loss behavior I know experienced something new. Yesterday I was driving a distance of 100 km. I started with 71% SoC and an expected range of 270 km. After approximately 30 mins of driving the car started to lose 1% SoC every 10-20 seconds. The outcome was that I arrived with 15% SoC (lost 56% SoC on 100 km). I was even thinking about stopping to charge in order to not get down to 0%.

For me personally this car is not reliable anymore and 100% a lemon car.

Exact same behavior here, during drive or just after startup... it's never reliable since the (not so) big update 5 months ago.
1% or more loss per day was preexisting behavior since September or October 2025 For my particular car.

Do you also experience erratic nav behavior regarding soc at destination? (For instance, here 26 vs 33%)

My particular turbo is obviously a lemon considering this problems AND my red circles of death dangerous issues That Porsche don't know how to fix.
can't wait to change it, and never buy a Porsche again,EV or ICE. Fed up with this costly brand that doesn't respect their customers (in my case).

Yes, I also experienced the faulty navigation behavior. All in all, there is not one information regarding the SoC that you can rely on. You are always driving blind and it's luck if you do not get to 0% during your ride.

My car was with the dealer for 4 days to resolve range reporting issues. I had various issues -
1) The % at destination was sometimes more than at start of say a 40 mile drive
2) Charging at home on a 7Kw charger I noticed the last 3 hours were only at 3kw.
3) The consumption being shown was obviously wrong - as low as 4 miles / Kw !
4) Sometimes the forecast consumption was obviously far too high

A couple of weeks ago the car went in for an appraisal prior to the 1 week booking. A small update was installed and it is suspected that the drop to 3Kw charging was caused by this update ‘initially protecting the battery’. This week they used their 11Kw AC charger twice to 100% and it was fine so back to normal. I’ll know more next week when I charge at home.
The system showed the car was due several updates (not a recall or campaign) - these were installed on the first day.
The inaccurate forecast charge at destination still exists but they hope that after doing the reset & updates that will settle as currently the car has no previous history of consumption to rely on.
The consumption showing now in the App is what I expect and seems to align with how much charge it took to get it to 100%.
I’m sure it is my imagination but the car feels smoother to drive.
In terms of what the updates were - all I could glean was that there were about 4 or 5 of them and one of them was definitely battery management.

I had an ICE Macan as a curtesy car - I hated it. It was loud, harsh to drive (no air I suspect) and it cost me more in petrol to do 25 miles than 300 miles in my car.

Being a glutton for punishment I have ordered a Cayenne EV Coupe and are being told currently it will be one of the first non press cars in the country when it arrives mid July.
