My dealer is at a loss. Twice the 2019 XC40 has been completely dead. Both times, after a few hours, it starts like nothing happened. I open the door, nothing lights up, nothing reacts, no lights, no sounds. The second time, I had been sitting in the car for maybe 30 minutes waiting on the tow truck. I was playing a phone game and the car lit up all if the sudden. I did nothing, key had been laying in the cup holder and the driver door was open. I was sitting in the driver seat. If anyone has any ideas, share them please..
