The car’s theft alarm goes on after rain. It normally takes one to two hours after it has stopped raining. Sometimes the hatch door lamp indicates that the hatch door is open, but it isn't open. The alarm can be turned off and after some minutes the alarm goes on again. Then it takes around one hour before it will go on again. Then the alarm is silent until the rain is coming. After I wash the car the alarm doesn't go on. The dealer has change the switch in the hatch door. They have also checked that all doors will be closed properly. The car has been parked inside a garage from 2011- 2015, and therefore the alarm hasn't turned on. Since June 2015 the car has been parked outside our new house and it was at this time the problem started. There is no indicating lamps of open doors, hood or hatch.
