Are you exclusively DCFC charging or what is your charging regime (AC vs DC ). -32C or -25F is seriously 😳 cold and any EV will have problems accepting a charge even with DCFC preconditioning. It sounds like you battery is cold gating, as mentioned in other posts. If traveling try to start with a warm battery and if you DCFC every 2-3 hours, the battery will stay warm. It’s amazing how Ford press shots showed Lightnings in cold snowy weather, but truthfully they are ill equipped to handle it. No DCFC preconditioning or use of heat pumps.
