Ford Fusion Hybrid High Voltage Error

I own a 2017 Ford Fusion Hybrid. Recently, at 23913 km, I received a high-voltage system error message. The engine shuts off and power is significantly reduced. Error is stored in the error memory. Could a discharged battery be the problem?

I had a similar issue with my Fusion Hybrid. It sounds like the car's electrical system is acting up. Have you checked the voltage sensor or the electrical wiring related to the high-voltage system? It could be as simple as a loose connection, or potentially a problem with the inverter.

Thank you for your reply. How did you resolve the problem? Was it difficult to diagnose, like finding a needle in a haystack?

In my case, the battery was heavily discharged and likely defective. I recommend you take it to a workshop. They can properly diagnose the issue, perhaps a faulty voltage sensor or a damaged inverter. Better safe than sorry.

I appreciate the advice. I took the car to a workshop, and it was indeed a battery issue. The repair cost 290€. Thank you for pointing me in the right direction.
