Rear passenger door won't lock. My wife "apparently" locked the car at work in an open parking lot and later went to retrieve something from back seat to find that the door was not locked. No indication was given when locking the car using the remote locking mechanism that there is an issue because it sounds like it is fully locked. It isn't. I checked the issue by having her drive up and down the road making sure she thought all doors were locked and while she had stopped, I opened the rear passenger door and jumped in the back seat much as an attacker or carjacker might do. This is a safety issue because anyone can jump in the back of the car while stopped at traffic lights even though the owner may think that the car is securely locked, it just might not be. Beware and check all your door locks on a regular basis as this seems to be reported on multiple occasions on Ford Focus internet forums. To this date, we have no idea when the actual locking mechanism failed as it is not something we, or any other driver would check on a regular basis.
