Official summary
Some vehicles with the two-step deployment control air bag module may exhibit a clicking sound when turning the steering wheel. This is caused by the horn spring (1) of the airbag module interfering with the black color tape (2) of the clock spring harness (3), resulting in a stick-slip noise (click on attached sound file below).
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
