My 2011 Edge with 17k miles on it doing the same thing. I took it in while under warranty, they "fixed" it long enough for it to go out of warranty now they want $350 to fix it. NO!!!! I saw a YouTube someone posted, will try that. I called Ford to report, hopefully they'll recall as this is a serious safety issue, driving with the dome light on at night can't be safe and going 70 mph down the freeway with the door unlocked.....
Yea, I'm done with Ford. Years of driving a Honda, should have stuck with that.
