Catastrophic engine failure while driving at highway speeds in dense traffic led to seized engine and highly dangerous situation. Root cause wasn't determined due to volume of damage. Three pistons, rods, and crankshaft where shattered beyond recognition along with a cracked block. Engine was highly maintained and showed no signs of failure prior. Completely torn differential bushings around the bolt sleeve with low mileage and roughly a year and a half from build date. Personal research shows that this is a highly common issues that remains unaddressed by Ford and safety agencies.
