Ecoboost dead battery but with normal voltage

[jewc75]

For future reference a fully charged 12v battery should show 13.4 volts and at idle should be around 14.4. Anything under 10.5 volts is considered a bad battery. Most dealerships will do a simple battery test which is the same thing an auto parts store does which doesn't give an accurate state of the battery.

I HATE THE DAMN IDIOTS AT THE DEALERSHIP. . . FFS FREAKING AUTOZONE WOULD HAVE DONE A BETTER DIAGNOSIS IN 15 MINUTES, WHY THE HELL IS A DEALERSHIP SHOP SO INCOMPETENT, HOW AM I SUPPOSED TO TRUST THEY WON'T TOTAL MY TRUCK DOING THE SIMPLEST THINGS

It's not a lack of intelligence. Ford knows exactly what the issue is, and if they acknowledge it, are afraid they'll have to replace batteries on thousands of Mavericks. So they play dumb and waste your time pretending to give warranty service. I wouldn't be surprised if there ends up being a class action lawsuit. Then you can fill out some ten page form in order to receive your $1.50 while the attorneys keep the rest.
