Well-- my otherwise flawless 2020 4S has failed me :(

Would love others' perspectives on what lies ahead for me. Here is the scene:
  • drove the car without issue the other day, garaged it with approx 140 miles of range (did not plug it in)
  • went to drive it a day later---range showed 25 miles
  • put it on the charger and had two issues: screen said 'Charging not Possible' and red light at the charge port
  • called Porsche Roadside to take it to the dealership
  • when they arrived, I had the red circle of death (Electrical System Failure) and car would not engage in either Drive or Reverse (and range down to 20)
  • car now at dealership waiting for service to open on Monday
  • never had any issues before- was routinely getting 225-230 miles of range at 85%
Uggh.....

Shit, that sucks. Hope you get more info on Monday and it’s fixable in a couple of days. Did you get a loaner?

Sorry to hear your 4S has succumbed. You'll find the cause, repair duration, and remedy varies widely. Join the club and the poll:
Dreaded Red Electrical System Error & Poll | TaycanForum -- Porsche Taycan Owners, News, Discussions, Forums

I was pretty lucky last fall when it only took 12 days in the U.S. from diagnosis to new HV battery. Key to speed is having a dealer with a HV battery trained technician on staff. Others have waited months to have someone from PNA fly to the dealer. In some cases, if HV battery related, PNA will often just replace failed modules.

You also may join the club of drivers who have had their HV battery recently replaced, like me, but still subject to the ARA4 HV Battery recall:
Recall: High-Voltage Batteries May Short Circuit (ARA4) - March 20, 2024 | TaycanForum -- Porsche Taycan Owners, News, Discussions, Forums

Good luck!

Sounds like mine over a year ago with one battery module failure. Shouldn't be a biggy to fix if they have a module spare...

I would expect to be without the car from 1-6 months. Took mine four months

Sorry about that. Went through it myself. Good chance you need a new battery pack, if it’s covered by warranty look at the bright side. You get a brand new battery!

also this tells me that no matter how careful you are with charging, doesn’t really change whether you will have a catastrophic failure.

Met with the service advisor this morning and explained the history of what happened. They could not have been nicer. They will have a tech on it first thing Monday morning and they give me a Panamera loaner.

Let’s see how it goes from here!

No updates yet---hopefully the tech will be able to check it out today.
UPDATED: tech won't get to it until tomorrow.

First update from service:
It appears your Taycan issue is traction battery related. Tech has sent the data to Porsche and said once they respond they will likely ask him to run a number of tests to confirm and he said, depending on how long they take to respond, it can take some time so I will let you know what the next step will be as soon as I know.
