Sorry to hear about what happened @jmeys23. People have had issues with PCM before. It could be a connectivity issue. Has it happened again since?
PCM not connecting. How to reset PCM?
Hello everyone, I am new to this forum, but I just got delivery of my 4s last week. However my PCM is no longer “active”. It isn’t connecting and keeps saying “activation is being processed” for the last week. I was told to reset my PCM but I can’t figure that out anywhere. I also contacted...

Service activation and connect problems
Yep. I have been back to dealer twice this week. Really disappointing that Porsche pushed these vehicles out without educating their sales team and maintenance personnel. It has been my WORST automobile experience in my life. Yesterday, I spent an hour at an Electrify America station. Could...

This is a SERIOUS problem - hopefully this will help - from a thread in the taycanevforum.com.
OK, I just got the word from my dealer and they are fixing the problem. I'll have more details tomorrow, but they spoke with Porsche on the problem and it is a 'communication issue' between the main ICU and the DME for the rear engine. They weren't communicating properly, and Porsche sent a software fix to the dealer which they are installing, and say will completely solve the problem. They said that Porsche 'missed' this in their major update, which is the cause of the issue. They evidently will be including this fix into updates from now on, but I asked if they would be recalling cars that are currently on the road and the dealer did not have any indication this would be the case.
I would definitely recommend asking your dealer about this, since the problem is very serious. I'll post again tomorrow after I pick the car up and have more detail.

Hi, Just picked up my 4S last week. I love this car. Got the Ice Gray.
Last Saturday at the end of a 120 mile trip in the mountains a warning light came on on the right Tube. I swear it said something about the 'engine'- that doesn't make sense. Anyway, at the bottom of the alert it said 'find a safe place to park'. I pulled in to a parking lot but didn't have enough time to park before the car stopped (I had less than a minute) and stayed in park. I turned off the car and turned it back on and everything worked fine. Drove it back to the dealer (in the slow lane🙁 next to the shoulder- no shoulders next to the fast lane). My representative told me he had heard from three other drivers of that happening. He said you need to turn off the car, get out, lock it which resets it and then turn it back on. Like Vim said, this is a SERIOUS problem. Hope there is a software fix.

It does seem like something that can be fixed with an OTA update. If it can't it's going to be a huge pain for everyone and Porsche to deal with. Keep us posted with what your dealer tells you.
He said, if it happens again this is what you do. Next time I'll snap a picture of the alert. Haven't found anything like it in the manual.
Just got my car back, and the problem was identified and fixed. It is a problem due to the latest 'update' and may not affect all cars. Evidently, the software controlling the communication to the rear engine is defective and allows the rear cpu to get overwhelmed and it just shuts down. Porsche has a 'patch' that they send to the dealer OTA, and they can install this patch in your car. As far as I know, I'm one of the first to get this done, so you need to tell your dealer to call Porsche and get the patch! Anything else is bullshit. As I said before, this is a very serious problem, and seems to be affecting a large number of post-update cars. I was told there should be some kind of announcement from Porsche, but they need to determine the extent of the problem and what cars are affected. Given the serious nature of the problem, I'd get the announcement out to the dealers at least...
So many bugs in the PCM. So far I've been lucky with my 4S. Twice now I've gotten messages saying " Emergency Service Required ". Simply hit the back button and they disappeared. Still holding my breath that everything will continue to function normally. Fingers crossed.
