TRUCK IS LESS THAN 3 YEARS OLD AND RECENTLY SERVICED AT FORD DEALERSHIP. AFTER RECENT SERVICE THE TRUCK WOULDN'T START. WHEN THE TRUCK WAS CHECKED BOTH LARGE FACTORY INSTALLED BATTERIES HAD CATASTROPHIC FAILURE LEADING TO BATTERY ACID CORROSION DESTROYING WIRING, POTENTIAL THE THE BRAKING SYSTEM AND OTHER ELECTRONICS THAT WERE EXPOSED TO BATTERY ACID AND CORROSION. THERE IS TREMENDOUS DAMAGE TO THE TRUCK AND A LARGE CHEMICAL SPILL FROM THE ACID. DEALERSHIP QUOTED OVER $1800 IN DAMAGES. TRUCK WAS A FIRE AND CHEMICAL HAZARD BECAUSE THE FAILURE WAS HIDDEN BY A FACTORY COVER, A HUGE COPPER CABLE WAS FREE TO ARC AND COULD HAVE IGNITED THE BATTERY OR CAUSED A DANGEROUS ELECTICAL FIRE.
