2014 Ford Flex Limited AWD
Please watch the 57 second video Basically the dash lights gives every single warning imaginable. Sometimes it wont start until a zillion tries. It does it while driving or not driving. Will go a month without issues too. Newer less than a year battery. The ground cable off the battery is secure. Not sure where to start. Figured something is wrong with the ECU or a ground is bad somewhere.

 

did you happen to figure this out I am having same issue

 

Did you figure a solution for this, going through it again but now it won’t start at all for 3 days

 

Light show during driving usually alternator or voltage regulator or bad ground connection, and NOT the battery.
No start, is it no crank no start or crank no start?
if no crank no start, it's a problem with the starting circuit, including the battery, but irrelevant to the charging circuit. You can crank with alternator completely removed off your car.
Crank no start could be a million things.
You have exact same vehicle same year as the thread starter? If not, check my signature below.

 

Sounds like a power interruption, which could start from power supplied to ign sw to power supplied from ign sw to rest of vehicle. Ground connections are also part of circuit.
Sometimes removing and reinstalling fuses one at a time can correct problem like this where poor connection is at fuse panel.
