Hi, I'm new to this posting site. I have a problem with my 750 volvo -- the door locks sometimes spontaneously lock while it is parked. This only started happening recently. The rear lights flash and the doors lock. I do not use a key fob, only the regular, manual key. Any thoughts on what is causing this to lock? It happens at my home, at my daughter's school and last week, in the parking lot of the local mall.
