Last Sunday, after our first week of ownership, my wife called while out shopping and said the Jeep wouldn't start. The message "key not detected" was on the MFD, even though the key was in her purse on the passenger seat. She tried placoing the key next to the START button, but no luck. I told her to use the fob to lock and unlock the doors and that triggered it to work. Then, every other day, this same thing happened. Yesterday morning, it seemed nothing we did would get it to recognize the key to start. One time when pressing the START button, I saw the message "Remote start not possible" on the MFD. I finally did something to get it started and took it to the dealer. They kept it overnight and were able to duplicate the problem. They fixed it by reprogramming the keys and the car electronics. Oddly enough, ours is a June 2011 build, and the referenced bulletin above notes that it's only for April and earlier builds. I hope what they did was a permanent fix.
