Mercedes E Klasse Hybrid High Voltage System Error

My 2018 Mercedes E Klasse hybrid is throwing a high-voltage system error. I have 176282 km on the clock. The error is stored, and the engine cuts out sometimes, also feels like reduced power. Could this be the EV problem I've heard about? I'm guessing a voltage sensor issue or something draining the battery, or maybe an inverter issue? Has anyone else seen this system malfunction?

I had a similar issue with my E Klasse hybrid. I'm not sure about the voltage sensor, but it sounds like battery drain to me. Have you checked the battery?

Checked it how? I mean, I saw the error message. Is there a way to check the battery myself? What did you do to solve it?

No, I didn't check it myself. When I had the same symptoms, error codes and everything, the dealer told me the battery was heavily discharged. I took it to the shop and they sorted it out. I would recommend doing the same.

Ok, thanks. It turns out it was a heavily discharged battery, just like you said. Cost me 290€ to get it sorted. I appreciate the help.
