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. They also told me i had to drive fast because its a muscle car and it would squatt upon going fast making the tires contact the road more even. After getting new, more premium tires and driving another 25,000 miles and the same thing happened at my 50,000 mile service, I started investigating and other year models have this same problem (years 15-23). I am in a situation where I have to put aftermarket parts on my car and potentially void my warranties and pay out of my own pocket. I have had an alignment 4 times and they say it is within specs but at the same time they say I do not have any camber adjustment left to prevent this problem. Ford makes an adjustable cam plate that is 410$ and another 480$ labor plus tax is almost a thousand dollars. Plus another realignment. This is not fair for a new car. I had to research myself and it was most definitely a safety concern. If I hadn't went right on time, I could have had a blow out. My tires have been properly rotated, and not driven in some bad way. It is also an environmental problem because I am throwing away perfectly good tires that are worn thru on the insides

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.
