NHTSA Complaint #11521971 — 2003 JEEP GRAND CHEROKEE

While driving at low speed, the side curtain airbags deployed along with the front seat belts. No injuries just stunted by the loud bang. I took car to Jeep dealership to have recall R06/15v-046 repaired and to diagnose cause of side curtain airbags deployment. Dealer would not repair recall R06/15v-046 due to the requirement that the side curtain and seat belts be repaired before making the recall repairs. Side curtain airbags repair was not accomplished because some repair parts are no longer available (seatbelts/headliner). Dealer indicated that, even if they could have repaired side curtain airbags that the cost of the side curtain airbags repair would be on me. Dealer charged me for a diagnostic of side curtain airbags deployment. I feel that the manufacturer is responsible for the defects and are responsible for restitution. Subject car has airbags light on know but not beforehand. What is my recourse now that my car is unsafe with no repair available and of little value?
