A little update here I went to mt buller yesterday, snow was great btw :) When I returned home it locked the doors. then I went down after 2 hours or so and took something from the car and doors didnt lock. I tried almost half an hour but no luck. opening the trunk and shutting hard helped once or twice. So I am suspecting it could be the trunk. I have one observation: when there is a literally open door and I try to lock the car it chirps immediately along with signals flashing. but when this problems occurs it first flashes the signal once then chirps. so the problem would be because of something else. or the computer messed up. I checked after 15 seconds the inside light dims. I tried pushing the trunk switch up with a screwdriver which shuts the trunk light so it means it's closed. but no help there still does that. I think whatever it happens or not I'll take it to the service before my warranty expires. Cheers
