NHTSA Complaint #11548828 — 2013 KIA RIO

I received a letter from KIA corporation that they would voluntarily replace a part (the clockspring assembly) in the steering wheel shaft as the malfunction would impair the proper functioning of the air bags, in the letter they stated specifically that this would not cost me any money out pocket including the diagnostic, I took the car to one of their dealers and they refused to service my vehicle if I did not pay upfront. I called another of their dealers but they also said I would have to pay for the diagnostic. I then called corporate and also corresponded with them via email but they did not solve the problem. Ever since I have been involved in two separate collisions and the air bags did not deploy, also the horn stop functioning and after doing some online research I found out it also depends on the part that was supposed to be replaced to function, the steering wheel control such as cruise control etc. also stopped working. Corporate has not gotten back to me and I feel they are just going to let it die out and not do anything about it. Meanwhile I am driving the vehicle without air bags, horn and steering wheel controls. I have no choice because my family only owns this vehicle. Please let me know what I need to do to get help to get a solution for this issue/s. thank you. Note: At this moment I only have information related to one of the collisions but I could provide for the other if need be. Also, the car belongs to my wife [XXX] ) but I was the driver at both collisions as I am the primary driver in my family household.
