My vehicle doors lock up and can't be unlocked due to faulty locks. No way to get door or doors to unlock. Which can cause death if involved in a roll over, submerged, or any major accidents. It can be any door on the vehicle. On mine it's my rear passenger door which my child sits next too in her car seat. I've read many other Volvos have this issue and very costly to repair. Volvo should be responsible as I have been told by a Volvo dealer mechanic that these S40 are very known to have this issue. For my experience of this happening is just driving home and parking. Tried to get my daughter out and it would not unlock. The key faubourg, the power lock switch and tried pulling on handle and nothing unlocks this door. I read that the lock actuators are the cause or its the wiring harness. I also have this problem in the trunk. Only the kid napped cord works to get the trunk to open. Please get Volvo to fix all there actuators before kids or adults get trapped and killed cause of their negligence.
