Loss of power on highway

[pschloes]

well... this happened: 70+ mph left lane of a highway (uphill) sudden loss of power, was able to coast to a (narrow) shoulder on the left with this message (attached). turned car off and resumed normal function upon restart... anyone else has seen this? 2025 4S 12k miles, latest firmware update a month ago...

Just noticed that whatever the glitch was it caused the car to shift into neutral...

Yes, total or partial loss of power, in town, b-road and highway... and several other variants of the red circles. In my case, the car doesn't always shift into neutral.

First, it was rare, and now, it occurs during each trip several times: the car is very dangerous.

4th time at the dealership (3-4 months cumulated). Always the same dealership statement: we "think" that the issue has been fixed.
This time is the last time for me and this Macan.

I'm pretty sure it's a very specific and rare issue.

This Electrical error known as the “red circle of death“ is a common occurrence and has been frequently posted on this site. This has happened to my car twice despite having it fixed the first time I’m currently in litigation with Porsche Canada and my local Porsche dealer I refused to take the car back and cancelled my agreement of purchase.
the car is dangerous.

Happened again to me this morning... agree with you, very dangerous. Uphill travel @ 80 mph with lots of traffic whizzing by.

there are several circle of death, and I've experienced many of them with and without partial or total loss of power. the car is dangerous, but in the meantime, the car is a beautiful 140k€ Christmas tree: red, yellow, white circle of death, some delightful bells and always a surprise when you take the car...
Hate it.

You likely have a 12v battery issue (or the electronics that provide the 12v to the modules). As the voltage drops, all the sensors start to enter undefined territory and emit random errors. 12v issues are the Achilles heel of cars these days, particularly EVs.
