How does one start a class action suit against Ford?

The problem is with 2005 Ford Escapes. The rear disintegrating inner wheel wells cause the shock towers to break loose and hit the inner storage area. The repair is expensive if you can find he parts and is a safety hazard. The problem was covered under a recall for previous years. I have also heard that problems extend as far as 2012. Ford refuses to acknowledge the problem. Most people in today's economy can't afford the repair or a new car.How does one start a class action suit against Ford - 1

IIRC the car should have a ten year rust perforation warranty…

I will have to check. I would assume it would be from manufacturing date?
