SgtRich... Ever since I closed the driver's door at a FedEx kiosk in the middle of a busy bank parking lot and had the Murano lock itself with the engine running, do I ever, ever, ever leave the key in the ignition or inside the vehicle and close the door.
First time it happened was 2 weeks after delivery, also at a FedEx location (pattern emerging?) but luckily I had the sunroof open and the back windows partially down. At the time I thought I had done something until I heard about everyone else having the same problem. The dealer won't fix since they can't seem to ever duplicate problem. Do a search for locks on the forum. Doesn't matter what the manual says.
