Same thing happened with me. I just checked carguru forum and there are about 20 post of this happening to Kia cars., not just Niro's. Has Kia responded with an answer yet?Sometime last night between 10pm and 9am, the clock in my Niro HEV stopped.
The display looks like --:-- and the Time/Date button in setup is grayed out.
Has this happened to anyone else?
