Door Latch problems of the 2006 Lexus GS300

Lexus Gs300 had 1472 miles, driver door opened & was over-extended by wind. Hinges separated from body & door misaligned. We complained from the time car was bought, the front doors swing too easily. On 2/9/07, front passenger door was opened , passenger entered & door would not close properly. Re-opened door to check if anything was caught in door, & nothing was found. Door would not close. Re-opened door & saw identical separation of hinge as on driver's door a year earlier. Vehicle has 8300 miles. Door had no mis-treatment prior to incidents.
