Three times now, I have come back to my car (2015 XC-60) and the dashboard is dead. Also the alarm spontaneously goes off at the same time..the alarm won't react to the key fob and the dashboard is dead and the car won't start. After about 20 minutes....the dash board spontaneously lights up and the alarm turns off and everything is fine.

The dealer had had no clue. I have brought it to the dealer and they can't find anything.

Anybody have ace any ideas?

 

Just a shot in the dark but see if the Dealer can disable the alarm and see if that stops the behavior.
