Clock spring assembly is mounted between steering column and steering wheel to provide the electrical connection between the steering column and steering wheel for steering wheel mounted switches and the airbag. Took the vehicle to the dealer where purchased to have a scraping noise within the steering column fixed that has existed since the vehicle was purchased new. Dealer informed me that the clockspring mechanism needed to be replaced as it was broken. Clock spring provides electrical interconnection to the horn (which works fine), the cruise control switches (which work fine), stereo controls (which work fine) and the airbag. Three of the four systems worked properly as verified through daily use while driving. The only system that cannot be tested by the driver is the airbag system. The computer for the srs is supposed to monitor all system components for proper operation (including the initiator mechanism for the driver side airbag) and provide a failure notification to the driver via a flashing airbag warning light on the instrument panel. No indication of system failure was ever provided by a flashing warning light. Dealer would not provide details as to what portion of the clockspring mechanism failed, but since three of the four systems that are connected via the clockspring worked properly, I have to assume the airbag system connection had failed. It is my opinion that this incident needs further investigation, since the obvious result could be failure of the driver side airbag to deploy as required in a collision.
