Paint problems of the 2009 Ford Focus

This car was purchased in 2010 for our daughter for college. After 6 months had to replace the tires. The mechanic replacing them warned us that on this car we would need to rotate them every so many miles because of the the way they ware out. Then at about a year started having trouble with the doors not wanting to open got to be the drivers door not opening at all. So had the Ford dealership fix it was almost $600. Long story short we have had to replace tires 3 times now , and we have them rotated every 3000 miles. As for the doors the back doors will not open at all, have not fixed them . We have fixed the drivers door again and also the passenger door twice also. We purchased the car for the gas mileage. And yes all cars have their problems but not like this . She now has trouble the the suspension, the ignition switch is going out and when the car was painted , the trunk was not primed so the paint is all peeling off. This is the most costly car we have ever bought. We will never by another Ford again.
