^As noted above, I seem to have the same issue. Many times I've been to the grocery store and had to pull over on the highway because the door ajar light is on. This last time, last week, I got out at a red light and slammed it hard to no avail. Had to pull over further ahead and gave it an even harder slam and that finally did it.
I haven't brought it in to the dealer yet, but next time I go in I'll have them look at it
