it seems to be the next level of the macan EV https://electrek.co/2026/02/02/porsche-cayenne-electric-enters-production-we-toured-its-battery-factory/

They probably will tell you it’s not under warranty and ask for thousands to replace it… Let us know…

It would be kind if you could try turning off you dash cam, and measure idling consumption. (I DM you for more context)

Do you have a dashcam or anything plugged in the car via usb or more directly into the LV system?

To people with 1% idle consumption: do you have dashcam or anything that is connected to your car, through USB, rain sensor wire or other powered source that is supposed to be off when the car is sleeping?

Another weird behavior, so now: - majority of the cars : 0% change, no matter idle time, 1 or 10+ days, - 20% (almost?) of the cars were in the first category, but for no apparent reason, they have fallen in the category of 1% loss per day, almost consistently. - Others: it depends and varies...

I agree, the App SoC is not reliable, even if some people on this forum don't like this fact... The app states that it has updated data, but for sure, it does't mean the data related to SoC have been updated with the latest incar value... It's probably one of the many problems of the server side...

And my loaner Macan (which is problem free) loses 0% per week in the same conditions as my Turbo, which loses 1% per day since the problem has appeared. (underground parking, no 4g/5g connectivity, stable temperature) 30kWh per month for 0 km/miles, I can't imagine it's "within specs" 😂

My car is at the dealership since 3rd of November, first for the red circle of death, and since 12/12, when they've said they've solved the red circles (which it remains to be confirmed), I've refused to take back the car because of the over consumption, 1% per day meaning 40 watts consumption...

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...

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...

The main reason is the Porsche will... and probably on the top of that some technical missteps when they designed the hardware of the Macan (The update of the electronic modules is PITA for dealerships with old procedures such as the need to connect the 12v battery to a charger, even though I'm...

As someone (@Yves ?) stated, the IX seems more efficient than the Macan EV. If range is a concern, check that. If there is no problem for you to buy a car that will not have any software improvements for years because Porsche thinks that it's better (?) to give the new software features only to...

100% agree. My car has the same issue.

Different car, different experience. My car is a total failure since this the last spring. My 50 cents in this rosy world of happy macan owners (obviously, Ì'm jealous) Frankly, I disagree with @Petzi 's story telling that there is no problem with Macan EVs, but I do agree with him when it...

I do understand better the way the LV battery is charged during idle thanks to this official statement.

Thanks, that helps a lot.

That's interesting to see the use of generative IA, and even thought the sources are displayed (here macanevowner, which is in fact us...), you think it's a reliable source to counter the same source ... frankly, unfortunately there is no official source to corroborate or not. Because of your...

I don't think so, for instance, my ex 2018 Tesla which had a 12v battery was not maintening LV battery when idling. And I guess, most of the EV cars with 12v system are not maintening 12v battery when off/idling. It's more or less like ICE cars, because this 12v powered onboard systems are...

@BigApple That's very interesting! I was pretty certain that the 12v battery is not maintened by the HV battery when the macan is off. Only when it'S on, and that's why some had 12v problems. how did you/they manage to change that behavior to cope with the drain of the dashcam?
