What can fail
The driver's side airbag clock spring wiring harness can break when the steering wheel turns to full lock while the suspension moves. When it breaks, the airbag deactivates, the airbag warning light turns on, and the horn and cruise control stop working.
What the fix does
The clock spring will be replaced with a new one that can rotate further without breaking.
