Hi, I have the european version of Niro PHEV, with the dashboard screen as on the video above ( i think it's first versions of phev). Had the same problem, went to my dealership, they said there is a problem with locking mechanism and asked to wait 2-3 weeks as they need to get the part from manufacturer. So I came home, and luckily found this thread. released orange button under the hood and it's started charging. Hope it will last... Thanks to everybody here for starting this thread!
