High voltage system error

I've got a 2023 Honda Stepwgn hybrid that's throwing up a high-voltage system error. Mileage is at 222512 km. Symptoms include the error being stored, the engine occasionally shutting off, and a noticeable reduction in engine power. I've checked for any obvious cable damage, but nothing stands out. Wondering if anyone else has run into this?

A 2023 Honda Stepwgn hybrid exhibited a high-voltage system error, causing the engine to occasionally shut off and reduce power. The issue was linked to an intermittent battery warning light. After consulting with others who experienced similar problems, it was suggested that the high-voltage system, particularly the battery, might be the cause. The problem was resolved by replacing the heavily discharged battery, which restored normal function.

I had something similar with my Stepwgn. Is there a battery warning light too? Could be an EV problem, high-voltage system related. I remember the power cutting out on mine.

Yeah, there's a battery warning light, but it's intermittent. Did yours give you any other clues before it went completely kaput? And how did you resolve it?

Sounds like the same electrical fault I had. Honestly, I nursed it for a few days, but the engine dying at random wasn't ideal. Best bet is to get it to a workshop to check the high-voltage system. Could well be battery-related.

Cheers for the advice. Took it to the shop, and you were spot on. Heavily discharged battery. New one fitted, and all sorted. Cost me 290€ Appreciate the help!
