9 systems errors at once

[Tighlines]

Yesterday I had 9 systems errors pop up at once while driving, the audio source even cut out. All errors said that the car was ok to continue driving but that it needed to be serviced asap. The driving dynamics of the car also changed when the errors popped up. Braking and suspension were the most notable. I drove it another 70miles after the errors to get home and it made it but all errors are still there this morning. The car successfully charged last night and I was hoping that the charge and locking overnight would have cleared the errors but no such luck. Has anyone else seen or dealt with this?

Can you check your battery terminals if they are secured tightly? A wide range of errors can come up when the 12V is drained or disconnected and car momentarily switches to the HV battery as failover. The errors will persist until the fault codes are cleared, ex. via OBD tool or MapEV Diag tool

The red cap was completely off but I dont think that affected the battery. The other connection i could see was firmly in place. Is there another hidden connector?

What you see there is the remote terminal post (meant for jumper cable connection). The black plastic cover can slide upwards to expose the actual positive terminal. See: https://www.taycanforum.com/forum/threads/routing-ctek-cable.23342/#post-517913

Use gloves and check both of those terminals are secure.

When you’re done, replace the cover and cover the remote terminal post with the red cap. It’s unlikely but a foreign object can touch on that post and to a grounding/chassis point and cause an electrical issue?

Everything seems to be firmly in place. It does make sense that is it something of that nature. How could so many different, unrelated areas of the car go into fault at the same time...? I have a service appt on Friday. Thanks for your guidance.

MapEV Diag if you want to actually know what is wrong with your car.

My experience when my rear motor was failing was that the car threw many codes that showed up when I scanned the car with my Foxwell i70BT scanner. I got no error messages displayed. Let the dealer look at it if possible. I was glad I had bought the extended warranty. Good luck.
