Since taking delivery of this vehicle in April I have intermittant failure of door locks, that is when locking doors only the passenger doors lock it takes numerous resets to work. The problem has recently got a lot worse and has had to be taken to Volvo dealership for further investigation. Has anyone else had similar problems.

Yes, I have the same issues. Door locks -- usually the left side doors -- don't unlock with key. When it gets in this state, the only way to get it to open is to get into the car from the other side and manually pull on the door handle. In this state, even the passenger door unlock control does not unlock the driver's door. Recent service to address this did not resolve the issue. I don't see any pattern with starting / stopping / restarting the car.

I also have the problem with the driver door panel controls not working -- meaning no windows can go down, no moving mirrors, etc.

Has anyone succeeded in getting this fixed?
