2006 Chrysler Town and Country Brakes & Aribag

I was recently involved in an accident in which I was going about 20 mph and rear-ended the car in front of me that abruptly slammed on brakes. My anti-lock brakes locked up (left skid marks ~ 3ft. long) and my airbag did not deploy upon impact (not at all!). To what would you attibute these two factors? Do you know who I should contact at Chrysler about these two issues?

Thank you,

L. Carleton
