"Onboard network error" - red - Taycan won't move - battery modules replaced

[Gkwan]

Hi guys,
Just thought I'd post this if it's useful for others.
My Taycan was parked in the street, I didn't use it the previous 2 days and had an errand to run, but I got a red alert (see photo) which completely immobilized the car, it wouldn't move an inch.
I tried a few on/off of the car : no effect
I tried off for >1h : no effect
I called Porsche assistance, they picked up the car the next morning and guess what : it worked, no more red flag when powering it up.

Porsche service was overall flawless except the first 2 loaners I got (Q5 hybrid, really bad, A3 better comparatively), good thing that the 3rd and last was a J1.2 Taycan 4S, really nice and brought me 1 step further to switching

Tech guy told me they identified 1 faulty HV battery module, and 2 others flagged as "potentially weak", so they ended up replacing the 3 modules under warranty.
Problem solved, I did notice a slightly better range than before.
I should get their intervention report "soon".

Cheers!

A typical "red circle of death" encounter.
In EU, those cases seem to be handled well and a lot quicker, than in the U.S.

oh ok, it wasn't useful then sorry!
Wish I'd have the luck to have more damage to get a full J1.2 battery, maybe next time

Yes, "hoping" that too. But ondeed please after stock of J1.1 modules is gone.

Sounds like a very quick turn around by Porsche? Good news at least!

Crazy low mileage for a failure but it is a 2020 I suppose....
