2014 Edge, 4500 miles, won’t start

[PaquitoGonzalez]

Greetings. We really need some help with our 2014 Ford Edge (US specs). We have taken it to the dealer many times and spent several thousand dollars in the last seven years for electrical issues--but the issues have never been fixed. 

 

The low mileage is because it’s always broken but the mechanic is telling me it’s always broken because we don’t drive it enough. Since we've bought it, we replaced the spark plugs at 1,533 miles, the battery at 2510 miles, a relay at 3326 miles, the FCIM at 3600 miles, another battery and a fuse at 4360 miles, another fuse at 4375 miles, and another battery at 4450 miles.
 

Inspite of all these repairs and regular maintenance, the vehicle isn't starting. Again. The dealer is recommending replacing the smart junction box and the HCU and ECU ABS modules. 
 

I’m banging my head on the advisor’s desk asking him to look at this holistically—this isn’t normal that a car (even one that’s seven years old) has so many problems of this type. Last time we replaced the battery, they told me THAT was the reason it wasn’t starting. They rolled their eyes when I told them the dead battery was just a symptom of a larger problem. 
 

So I’m not sure if they’re playing darts with their diagnoses, or maybe they’re recommending replacing the smart junction box because they know it’s out of stock nation wide, or if they legitimately diagnosed the problem this time. 
 

anyone got any suggestions?
