Talisman Undervoltage Error

I also have a Talisman and experienced something similar last year. Have you checked the battery's charging system? It might be a voltage regulator issue or a voltage drop somewhere. How old is your battery?

I haven't checked the regulator. Where is it located and how can I test it? The battery is the original one that came with the car, I think.

I'm not sure about the exact location on the 2022 model, but a workshop should be able to diagnose it quickly. Given it's the original battery and you're getting undervoltage, it's likely heavily discharged or defective. Could be time for a replacement!

Thanks for the advice! I took it to a workshop, and you were right. It was a defective battery. Cost me 290€ to replace. Appreciate the help.
