Has anyone else experienced the driver side door locking on its own after leaving the vehicle? After returning home on two occasions, the driver door was locked when I went back out to the car. Initially, I just thought I had inadvertently just locked it and didn't realize it. This morning, I let the vehicle warm up, and with the keys still in the ignition, ran back into the house to get something. When I came back, the door was locked again. This time I know I did not lock it myself. Fortunately, I have my extra set of keys handy to unlock it. Is this supposed to be a safety feature? My own garage or driveway is the only place I leave the car running for a short period of time. Perhaps this is to prevent someone from stealing the vehicle for those who leave their car running when they go into convenient stores?
