“I had to put 3 sets of tires on my car by 50,000 miles. The Ford company told me to go to an alignment specialist because without putting some sort of aftermarket part on my car they can't properly align it and they are tired of fooling with it. I had taken my car for a regular 25,000 mile service, and my tires were so bad that the Ford company would not allow me to leave without rotating the tires. They told me that new tires are soft and not good quality really, they are for selling the car so they are soft rubber. …”

“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.”
