Kuga Overvoltage Error

I'm having a weird issue with my 2020 Ford Kuga Hybrid. I'm getting a persistent overvoltage error. Mileage is at 30095 km. The car's throwing a ton of fault codes related to it, some systems are failing intermittently, and the battery seems weak on startup. I suspect a potential power surge or something messing with the ECU. Anyone experienced something similar with these symptoms or can point me in the right direction?

A 2020 Ford Kuga Hybrid is experiencing a persistent overvoltage error, accompanied by multiple fault codes and intermittent system failures. The issue may be linked to a weak battery, which appears to discharge while the car is off, suggesting a potential power surge or ECU problem. A defective battery was identified as the cause, and replacing it resolved the issue.

I had a similar issue with my Kuga. A bunch of electrical faults and overvoltage warnings. Did you check the car battery?

Yeah, the battery seems fine, but it looks like its discharging while the car is sitting turned off. Could it be a voltage regulator issue?

Possible. But in my case, the battery was heavily discharged and defective. Check it out at a workshop. Good luck!

Thanks for the insight! Indeed, it ended up being a defective battery. Cost me 290€ to replace. I appreciate the help!
