Toyota Noah high voltage system error

Alright, gearheads! I'm freaking out a bit. My 2015 Toyota Noah hybrid is throwing a high-voltage system error. I've only got 30423 km on the clock! The error's stored in the memory, and the engine keeps shutting off, like, totally randomly. Plus, engine power is way down when it does run. Could this be a battery drain issue or something worse, like an inverter problem? Anyone seen this EV problem before?

I had a similar issue with my Noah. Is your battery warning light on? Sounds like the high-voltage system is cutting power. Could be a heavily discharged or defective battery.

Yeah, the battery warning flickers sometimes, but it's not constantly on. How did you figure out it was the battery? Did you get any specific codes?

No specific codes that I recall, just the system malfunction light and the reduced power. Honestly, I didn't dig too deep myself. With hybrid systems, it's best to take it to a workshop that knows what they're doing. They'll have the right diagnostic tools.

You were spot on! Took it to a specialist, and it was indeed the high-voltage battery. They replaced it, and the error is gone. Cost me 290€, but now she runs like new again. Thanks for the heads-up; I really appreciate it!
