Starter problems of the 2012 Ford Edge

"door ajar" - my 2012 Ford Edge sel will have this problem on a daily basis intermittently throughout the day. Door will be closed & dash will light with door ajar warning. At times the warning will go away & auto lock will lock after I start driving. Other times I can make a long drive & open & reclose the door numerous times without the warning going away. Because the door just randomly thinks it's unlocked during the day and night time this in turn makes my sync system interior lights & sometimes headlights and taillights cycle on and stay on for different intervals as witnessed by my many neighbors, husband & myself. This has had a drain on my battery & we have had to replace it & jump it before. Also, we are expecting our first child & are very concerned about this issue because we cannot make the car think that the door should be locked. We live in texas where it's quite hot & can be cold for infant in the winter I need to be able to have a remote starter to pre-heat & pre-cool my vehicle for the baby. I cannot leave vehicle unlocked when running because I have a neighbor with dementia who will get in the vehicle & try to drive away so for me this is a huge safety concern. This also gives Ford a bad reputation just by everyone in my subdivision seeing this car and it's erratic cycling of lights interior and exterior. If someone is trying to mug me or rape me I cannot even locked myself in my vehicle because it will lock the door and they will automatically unlock when the vehicle is running because my door "is ajar". I have read many postings all over the internet & youtube with people having the same problem with many Fords especially a 2012 Ford Edge. This is our fifth Ford vehicle for my husband & myself. My dad worked for Ford for a number of years & was a manager at a Ford, but safety issues for my family like this making me not want another.
