Would all these problems relate to this? SAFETY RECALL G28 - IGNITION/PARK SHIFT INTERLOCK. About 6 months ago the air bag warning light would come on intermittantly, now it stays on. Also, and not all at the same time, cruise control, horn and radio controls on the steering wheel don't work. Now the key switch has become more and more harder to turn and sometimes takes a bit of jiggling in order to operate. Will replacement of this "shift interlock" cure these problems?
