Could you elaborate on what specific symptoms you observed? Was it a gradual decline in performance, or a more abrupt stop? And what was the eventual fix?

Yeah, mine was more of a gradual thing. Like, it felt weaker and weaker, and the battery seemed to drain faster than usual. I ended up taking it to a workshop, and they sorted it out. Honestly, I'd suggest you do the same. Sounds like it could be a voltage sensor or the inverter. If you keep driving, it might just get worse and could damage something else.

Your advice was right: it was a defective voltage sensor on the high-voltage battery. The shop replaced it and recalibrated the system for 290€. Thanks for the help, it guided me to a quick fix.

Whoa, that sounds rough! I've got a Jazz too, though I'm not sure of the year, and I remember having something similar happen a while back. It wasn't exactly the same, but it had to do with the EV system acting up. Is it super sluggish, or just cuts out completely? For me, it felt like the car was running on fumes even with a full tank.
