At first it was thought that just one assembly plant was to blame, but they expanded to cover just about all of the 04-08s. The recall itself is not a big deal - it being fixed that is. My service took 1.5 hours
The chaffing of the airbag wire against the clockspring is a big deal. Once the wire's casing is rubbed through the airbag can deploy randomly, causing pretty decent injuries. The airbag light is supposed to illuminate prior to deployment as an indicator that the wiring has gone south.
