Unfortunately this didn’t do it for me. I turned off the battery conservation feature a few months ago after the 1% drain started, and it made no difference.

Thank you! You are right. I think I'm going to wait and see if a software update improves the situation, because I do enjoy the car a lot and wouldn't buy another model right now. If the issue gets worse, I'll consider pushing for a trade-in. For now, I'm still hopeful they're working on it...

False alert, still reliably losing 1% per day 🙃 The dashcam and its external battery were not the culprits. I'm just going to ignore this issue until they fix it. I've wasted too much time trying to troubleshoot it. Dealers are clueless, Porsche pretends it's normal (for now). I could try to...

Well, the battery drain may have gone away (!) I charged the car to 90% for a road trip on Wednesday morning, and when I took it today (two days later), it was still at 90%. This has not happened since July. That said, it’s a bit early to call this a fix, so I’ll report back soon. The two...

It was my hope as well, and based on this thread (which is, in all fairness, a small group of self-selecting owners) it doesn't seem like they've this technology under control just yet. I see it as growing pains of a manufacturer that has been doing gas engines for the last 70 years, and is –...

@EVowner 🙈 hopefully this works for him. You need to be quite immune to embarrassment to drive around trying to raise awareness on issues with your £140k car. They definitely know, and likely working on a fix. @byebye definitely curious to know if the Guest account workaround works for you.

I’m wondering if all this energy has really dissipated or if the SoC indication is unreliable (possibly both). Because I’ve definitely observed the latter.

Agreed! I did bring it again because of the slow DC charging issue, but I’m thinking I should have tried to troubleshoot both issues myself, since I don’t think anything has changed after their intervention. At least now I have the latest updates.

I did suspect this as well, and told them to test exactly that. But I’ll try on my own. How do you know it takes longer to enter sleep mode?

Yes, but they disconnected it when they tested. That said, it doesn’t hurt to try disconnecting everything again on my own.

Did you get a recent software update? I assume you didn’t. I’m getting my car back tomorrow after it spent 3 weeks at the dealership (for this + the slow DC charging issue). They could replicate the battery drain, sent the data to Porsche, and after careful consideration… they’ve decided to...

Good to know, and indeed I'm not quite sure how they installed mine. I believe they didn't use the OBD port, but I may be wrong. I went with the battery because that's the only way you can get to 10-15 days of parking mode, which you may not need?

I also have a Thinkware U3000 with an external battery, and have been happy with it. Main reason I got it is because it was the only one with an extended parking mode (~10-15 days), which I need because my car is parked in a shared underground garage. I remember my installer struggled to find...

As a Turbo owner, this is not going to sound objective, but... did they say that primarily because of the suspension tuning? (Assuming that's the main/only difference.) I already find the Turbo too sporty, leaning on rough for the NY roads (at least much more than my previous non-EV Macan GTS)...

You’re aware they’re incentivized to have you buy one of their cars, right? 😛 Also, they can’t have already forgotten how many issues the first Taycans had. When I talked to a salesman after I first got issues with my Macan EV, he had hard time hiding that I was not the only one. He said a...

I’m wondering if we should start a shared Google spreadsheet with standardized data recording the daily battery drain issue across this forum. If we have a consistent pattern across enough cars that we can share with Porsche, they may start caring a little bit more. Thoughts?

Yeah, I took a look today, lemon law doesn’t look at all like an easy process, I’m not there yet. I’m bringing the car back to the dealer next week, let’s see if the slow DC charging issue changes anything. I also contacted Porsche on the side, but I’m not super hopeful they’ll do anything.

Thanks! I think I’m going to ask the dealer to run and document these tests, I don’t have that kind of time (at least for now) 😄

I’ve been curious about this indeed. I’ll research the best way to bring it up to the dealer.

If you know someone at Porsche that could bump up the priority of this issue, don’t hesitate 😛
