Just like all of the others, my Ford Flex has the door ajar problem. It thinks the door is open when it is not. Because of this it will not automatically lock the car when I start (I have toddlers so this is important). It is draining my battery. The alarm is randomly going off in the middle of the night, too. I brought it in and Ford says they cannot replicate the door ajar problem. I show them all of the complaints and it does not matter. What a joke. I loved the car for three years and now tell everyone to stay clear.

CONSTANT DOOR AJAR WARNING WHEN ALL DOORS ARE CLOSED (OR OPEN) DRAINS BATTERY AND CONTINUALLY SETS OFF CAR ALARM. DOORS NO LONGER LOCK WHEN CAR IS IN MOTION. DOORS CANNOT BE LOCKED ONCE PARKED OR ALARM WILL SOUND WITHIN 10-15 MINUTES. ISSUE HAS DRAINED MULTIPLE BATTERIES AND STRANDED OWNER. DOME LIGHTS COME ON UNEXPECTEDLY WHILE DRIVING AT NIGHT - ISSUE OCCURS ON STREETS AND HIGHWAYS. FORD DEALER RECOMMENDS REPLACING ALL DOOR LATCHES AT >$200 A PIECE WITH NO GUARANTEE OF ISSUE NOT RECURRING. 

This is a recurring issue and and incredibly expensive repair for a faulty switch (~$600 with parts and labour).

In our case this has happened twice, this complaint outlines the first time (date and mileage is an approximation since I'm entering this complaint after the fact), but there are many reports of this happening many, many times, even on the same vehicle.

The first time for us was the drivers side front door. Luckily this occurred during the term of our extended warranty and was repaired without charge , eventually... (It took a LOT of complaints/arguments with the dealership service dept manager and Ford Canada to have the dealership categorize this as an issue with the safety related "door ajar" section of the warranty... They initially insisted on it being categorized as the door latch, which apparently wouldn't have been covered...)

Not looking forward to the next door sensor to go... but fully expect it too... very disappointed...

Me....Again :( Now the 3rd faulty sensor on the passenger side back door is acting up. Called Ford Canada to log the complaint - I actually spoke with the same rep as back in May...she noted my concern. I'm going to take another run at her useless boss. NEVER AGAIN WILL I BUY A FORD PRODUCT....EVER. They need to do right by their customers, put on their big boy pants and own up to their mistakes and crappy products. Come on Ford - be bold! take the hit on the chin and your big bonuses to take responsibility for the junk you produce. I will not go back to a dealership to have anything fixed and will look for aftermarket parts where possible. I really used to like Ford - I guess things change. SUCH a disappointment taking a chance on a North American brand again...their bottom-feeder reputation for quality has not changed.

The door ajar light has been coming on in my Ford Flex for months and months. I took it to the dealership a few months ago for this and they sprayed lube in it but did not fix the problem. I took it back a few days ago while it was doing it and showed the service writer and left it running so the tech would see it. So after waiting 1 1/2 hours I went out to see what was going on and the tech came over and said they could not duplicate it. So I said I have been sitting here for this long and you didn't fix it!!! So he turned it over to another service writer, mine was at lunch. He told me they would have to order the part for it and would call me when it got here. I have extended warranty with a $100 deductible. I told the service writer there was a universal problem with these door ajar lights on escapes and flexes I believe, and Ford Motor needs to man up and pay for it!!!!!!!!!!!!

When the light comes on, it thinks the driver's door is not closed, so it keeps binging and says door ajar and shift to park and the inside lights come on. But it all stops until you are driving and you stop and then go again, and it starts all over again every time you stop at a light or for whatever reason you stop. It is starting to come on at night while I am driving down the road for no reason and it makes it very hard to see the road when the inside lights are on!!!!!!!!!!!!! Very annoying and could lead to bad things, especially if I can't see the road at night!!!!

This type thing is what really worried me of all the electronics on these new vehicles. All started in February when needed to go to a funeral and the remote key would not start it. Once returned in two days called roadside assistance and they said it was the batteries in remote start switch. Fixed and bought two new spare batteries. Then lights inside would not work when door opens and still doesn't unless this replacement of the door switch solves that. Next the front passenger door "NOT CLOSED" light comes on and can turn off so know it is closed.

NEXT the car alarm goes off at 11:00 p.m. And wakes my neighbor and he comes and tells me. I don't know what to do but it shut off when I got in and started it than shut off. Next day the alarm goes off again at 3:00 p.m. And I catch it.

Call dealer and set up and now 3 days later I am getting my car back with an awful bill. Obviously this Ford is going to be expensive to maintain. ??? $500 plus dollars for the diagnostics and a switch and a fuse. May have to seriously have to consider getting an older car that's more maintenance free like a Honda or Toyota.
