Mirai seat heating malfunction

Experiencing an issue with my 2022 Toyota Mirai (electric engine). The seat heating elements don't generate warmth, and there's an error code. Suspect a defective seat heating mat. Anyone else encountered this?

I have a Mirai as well, and your issue sounds similar to what I experienced. The seat heater would just not get warm. Did you check the fuses? Sometimes it is just that. Although a stored error code suggests something more substantial.

Thanks. I did inspect the fuses and they seem fine. Could you elaborate on your issue and how it was resolved? What diagnostic steps did you take?

In my case, it ended up being a faulty heating element in the seat itself. Unfortunately, there wasn't a simple fix. I recommend consulting a qualified technician for a thorough inspection. It will probably need replacement.

Thanks for sharing. Based on your recommendation, I had it inspected by a certified technician. The diagnosis confirmed a defective seat heating mat. The repair, including parts and labor, amounted to 390€. Your insights were helpful in resolving this.
