One problem related to tailgate has been reported for the 2013 Ford Edge. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2013 Ford Edge based on all problems reported for the 2013 Edge.
Starting in February 2017, the 'driver door ajar' warning indicator would not turn off when the driver door was closed. The vehicle had about 90,000miles. None of the three passenger doors or the tailgate have this same issue. At first the problem was intermittent. I tried to lubricate the latch with silicon spray and the problem would go away for a week, then come back. It progressively got worse until June of 2017, when the problem would not go away at all. Slamming the door shut repeatedly did not work, the driver door ajar warning stayed on. Because of this issue, it's hard to tell if the door is really closed or not. If the door is not latched properly, it would be a severe safety concern. In addition, the doors no longer lock, neither automatically nor using the lock switch which also presents a safety concern. Another result of this problem is the interior lights do not go out when the car is off and the door closed which has drained the battery on several occasions. Please look into this issue as a major safety concern, especially in view of the doors not locking when the vehicle is in motion and the uncertainty as to whether or not the door is actually closed.
