2005 Ford Focus suspension problems

This is about a 2005 ford focus zx3, bought new with 8 miles on the car. Driving along @ 65 MPH & according to witnesses in back of car, the driver-side front wheel came off of the car. The car then fish-tailed then started flipping front end to back end 5 to 7 times for a good 100 to 150 feet along the side of the road. The car was totaled and because of a seat belt there was only minor injuries.

We purchased our 2005 ford focus zx4 ses brand new in february 2005. Since the date of purchase we have had to replace the rear tires 5 times, two of the 5 times we replaced the whole set. The original factory tires on the rear of vehicle (yokohama 205/50/zr16) were bald at 11,000 miles. At that time we replaced them with 4 new yokohama tires. Six months later, we had to buy another complete set of tires (michelin/205/55/r16) because the tires in the rear were cupping and wearing in a diagonal cross pattern.
