Speed Control Springs problems of the 2013 Toyota Prius

Often referred clock spring as it is referred to part number 84307-47020 it affects a multitude of things on my car that are safety related including the horn, the buttons on the steering wheel that control the radio and tricks odometer, the airbag, maybe be airbags plearle, be adaptive cruise control and maybe other things. My knowledge my car has never been wrecked or had airbags blown and this is very premature for this part to fail. Believe Toyota should take responsibility for it. The warning light came on and it says in the manual that is unsafe to drive. Do not have a clue why it failed. The Toyota dealer repair is close to $900 which is ridiculous.
