Hyundai i10 Undervoltage Warning

I'm having a weird electrical problem with my 2022 Hyundai i10, gasoline engine. It's got 181220 km on the clock. Basically, I'm getting undervoltage detected warnings. It starts poorly, some systems are failing, lights are flickering, and the battery seems weak when starting. Anyone else had this? I checked the battery terminals, they seem ok, but I don't know what else to do!

A 2022 Hyundai i10 with 181,220 km is experiencing an undervoltage warning, poor starting, system failures, flickering lights, and a weak battery. The issue is likely due to a heavily discharged and defective battery. Replacing the battery resolved the problems, restoring normal function to the vehicle.

Sounds familiar! I had something similar happen with my i10 (don't remember the year). It was like the car's brain was slowly shutting down. Was the undervoltage warning constant, or intermittent? Did it get worse over time?

Good to know I am not alone! It started intermittently, but now it's pretty constant, like a bad toothache that won't go away. It's definitely getting worse. What was the cause in your case?

Yep, that's exactly what happened to me. It turned out to be a heavily discharged and defective battery. Get it checked out by a workshop. Cost me around 290€ to replace, but it solved all the problems.

Thanks a lot for the help! I took it to a workshop, and you were spot on. The battery was toast! Replaced it, and everything's back to normal. You saved me a lot of headache!
