As anyone ever experienced this; my 2017 etron after more than 6000 km or 3700 miles switches to hold mode, with a full charge, when driven over 20 km/h or 12 mi/h? After the ICE warms up EV becomes available again but only under these speed. I have no warning or error displayed, and this is the first issue I ever experienced even after driving it in very cold weather here in eastern Canada.
