The famous RED DEAD electrical circle

[AnloTaycan2022]

How many of you have got that famous RED circle and few hours later it went away and the car worked normal. I had this issue yesterday night. Nothing worked even after locking the car for almost an hour. This morning the car started just as normal!!!!

If you have got a similar situation, have you got the car inspected and what was the result of such inspection? Why did it do that and then dissapear. Has it come back for you or never reappear?

2025 model. Ive had this a few times, and each time it was because my 12v died due to me not driving the car for about 2 weeks. That's what they told me at least. The error would go away if I let the car idle in place while turned on for about an hour.

I really wish this car was able to keep a charge better on the 12v. Especially because I keep it plugged in. Never had a car with such a delicate 12v.

I don't think that is the case for me as I had just driven for one hour before this occurs. Also, this morning after putting it back on the charge, I got a charging error now on the battery and the red circle came back, so this seems to be a solid issue now and most likely related to the high voltage battery. I will discuss with Porsche tomorrow morning at the opening

There is a recall for an update to the 12V battery sensor for a lot of Porsche models.
Maybe that solves your problem.

Had this happen a couple of weeks ago. Left the car for a couple of hours at a store parking lot, error went away on its own. Had service diagnose, they found the faults in ECU history, did some additional diagnostics, cleared the errors, but found nothing actionable. My car already had the 12V recall done.

No problem since I've had it back & repaired.

. In my case it ended up to be the HV battery heater that went kapout! This alert in the end is for many types of issues. I got my car 2 days later in my case and here they give us a Porsche as loaner.

oh ok, glad for you that it's solved
Taycan J1.2 I got as 3rd loaner was really nice to drive for ~10 days, even though less specced than mine (4S vs Turbo, same 21" wheels, RAS in both, no PDCC in both), which makes me think they must have tweaked a few somethings that make the J1.2 slightly more comfortable than the 1.1 with same specs
