Carrier/rack problems of the 2004 Mazda Tribute

I noticed the problem when I was driving down the road and heard a knocking coming from the rear of the vehicle I thought it was a bad shock at first so I pulled over to check it out and the rear shock brackets are completely rusted through and are breaking away from the main frame. I contacted Mazda on July 11, 2014 and they said they will not do anything until teh car is recalled. They havent provided any other info on assitance with repairs or a recall. The car is no longer driveable until it goes through massive reconstruction of the sheet metal and framing in the rear wheel well.
