Underbody Shield problems of the 1998 Nissan Pathfinder

How can a major car company build a vehicle that has so many rust problems. My 1998 Pathfinder has so many rust problems. The company has had recall on the front strut housing, filler gas tube. Why can't the company stand up and take care of all the rust problems. Ever 1998 Pathfinder has rust issues fenders rear quarter panels . If you paid $1000,00 for factory running boards they all have rusted off. Why is it that the owners have to accept the problem with all these rust issues? this is my first and last Nissan I will ever own. Oh did I also tell you the transmission has been replaced, rear end makes noise,the distributor has been replaced filler tube, now the strut tower is rusting. Is this even a safe vehicle to operate on the road?.
