Air Bag On-off Switch problems of the 2009 Toyota Tacoma

I have exactly the same problem with read leaf springs as everybody else- the rear is sagging and and the front end is starting to rise(excessive tire wear) my truck has 66,000 miles and it only carries a 210lb vintage dirtbike 5 or 6 times a year. Do people have to start dying like gm's ignition switch before someone in the federal govt gets off their rear end and actually does their job? also spiral cable recall that could damage driver's airbag(cob (c1b) I have paperwork from Toyota and dealer stating the recall and now they are denying that one exists or ever existed. Also, when transmission shifts at low speeds(usually downshifting, clunk is heard in drive shaft) too much lash in rearend or junk u-joints. I have an aas in automotive technolgy and over 105 credits in automotive engineering . I'm not just blowing smoke. When I lived in nys, I had a vehicle inspection license and I would definitely fail many Toyotas with these problems. No inspection sticker-no driving of vehicle.
