I have a Ford Flex 2013 and I love it but this door ajar is a little disappointing, 3 of my doors have this issue and have called dealer and super pricey just to diagnose the problem plus whatever it is to fix it. Now my driver door has as much times i tried to close or slam it, it wont and it will beep every time I get my foot of the brake. Now the only option for me is to ground that wire to the car which is not the fix I want but its the only option I have. If anyone out there has a better solution please let me know.

I have owned 3 Ford Flex. A 2009 that had not issues whatsoever. A 2013 Limited that had door sensor issues. Trade that and went to a Buick. Missed the Flex so we bought a 3rd one. Another 2013 but an SEL this time. SAME DAMN PROBLEM!!! After owning it for 2 years the sensors starting going out. We've had 2 replaced but the drivers door is the absolute worst! It is obviously the most used door and it's gotten to where it is continuous and we've had to replace the battery. This issue should have been recalled long ago. Ridiculous.

SO OUR CAR ALARM WILL GO OFF IN THE MIDDLE OF THE NIGHT DUE TO THIS PROBLEM. WAKER THE WHOLE NEIGHBORHOOD UP. IT ALSO KEEPS THE LIGHT ON FOR A WHILE WHEN WE START TO DRIVE WHICH MAKES IT HARD TO SEE. WE HAVE STOPPED PUTTING THE ALARM ON AS IT HELPS TO OT HAVE THE SENSOR START THE ALARM BT THE OUR CAR IS IN DANGER OF BEING ROBBED. VERY FRUSTRATING. NOW WE HAVE TO HAVE THE CAR FIXED FOR THE SCOND TIME. A YEAR AGO IT WAS ONE DOOR AND NOT ANOTHER BUT THIS TIME OUR WARRANTY HAS RUN OUT SO WE HAVE TO PAY 376.00. REAL FRUSTRATING.

Already replaced back passenger sensor. Warranty is out so cost is $500 to fix the passenger front door. Have to keep opening and closing to get it to shut off. Already replaced one dead battery. Dome lights stay on continuously dings and kills battery. Now the sensor light came on and door was not even opened. Can't use door or have a passenger in front seat because the door will have to be opened and closed until the door sensor light goes off.. I have read lots of reviews that this is a problem with this year of Flex.. and now I am reading there was a lawsuit filed last year.

My right front passenger door sensor has been sticking "door ajar" light remains on for about 6 months. At first I thought it was my kid not shutting the door all the way. Then by February 2018 I started to realize it was the car not the user. Now my spouse can't even sit in the front seat of our "family vehicle" because the last time he got out of the car we didn't think we were going to be able to shut the door enough times to get the "door ajar" light to trigger so our kid has to sit in front by climbing the seats! Also even when we don't use the door, I've noticed more and more that something will trigger it and the light will be on when I go to start the car. The dome lights are supposed to automatically turn off, but they don't, when I go to move my car when my spouse gets home from work that's usually when I find the lights are sometimes on, sometimes not & I'll get just the light on the dash and the dome lights when I start my car. Also I'm now having issues with the battery that was replaced last year so it should not have any issues. However a couple of times I've come out to start my car in the morning and the "door ajar" was somehow triggered and my car battery is low. The lights are on when I'm driving through neighborhoods because I'm driving at a lower speed and I can't shut them off because of this stupid "door ajar" light. I can't lock my car doors when it's triggered, not when the car is in motion or off. This is dangerous as I do have a young child and car theft is serious in my area. This is getting ridiculous as this is something that ford needs to fix, this is not just an annoyance, it is a safety issue. Having to drive with the dome lights on, not being able to lock the car at all, in motion or parked, battery dying, heck one day I'm lucky the car started after getting groceries. From what I have read, once one door does this, another door is sure to follow until all have had this issue and the parts been replaced... this sounds very much like Ford should just recall and fix the darn doors!

I bought this car used to replace my Taurus x. I thought that the little issues with the Taurus made this a good investment. Instead I have had nothing but electrical issues starting with the radio control module. The door latch sensor is a real pisser. It takes hours to turn off the warning lights and interior lights etc. We just keep slamming the door until it turns off and exit out of another door.Not fun when you are in your sixties.The light comes on whenever it feels like and causes the car to stall. The interior lights;All of them, come on whenever they feel like it. Driving down dark country roads is hazardous because there are no street lights and we almost collided with a group of people crossing the road at night because of the night blindness and not being able to see out the windows with the inside lights on. If they do not want to recall this, then at the very least have the new sensors installed at an affordable price. Ford knows there is a problem. I work at a factory that supplies the doors and they know it is a problem. It has been investigated more than once and now someone should do the right thing before I get a lawyer involved and file a class action lawsuit. Lets start putting parts that are premium on these cars. This cheapening of the product does not work. This will probably be my last Ford.

Dangerous when pulled off side of highway and tried to remedy by closing door harder. Occurs practically every day. Slamming door sometimes helps. In addition to door open icon, the doors will not lock when driving when lock switches are pressed and auto lock does not function. DANGEROUS situation especially with child locks in back and when driving in "bad" high crime areas!

Update from Aug 27, 2018: Ground colored wire to switch. Will keep door ajar warning from coming on (whether door is opened or closed) therefor it is not a true fix but a work around that works to prevent dead batteries, false alarm triggers, overhead cockpit lamps from staying on. I works for me since Ford says there is no easy fix and the switch (latch) must be replaced but that it can go bad again. There are 5 such switches including tailgate and they will go bad. Only 1 Ford Service Adviser I spoke to said this was a safe work around but of course could not authorize it but it would work as I describe and it does work. With all materials present the fix takes between 1/2 to 1 hour, but is a PITA. How to's are on You Tube, and wire diagrams on FixYa to find wire colors (ones closest to switch are the ones to use --wires are small)
