Due to a manufacturing issue, the NADI inflators may absorb moisture, possibly causing the air bag to deploy improperly in the event of a crash.
ELECTRICAL SYSTEM
ON CERTAIN PASSENGER VEHICLES EQUIPPED WITH HALOGEN LOW BEAM HEADLIGHTS, CERTAIN CONNECTOR PINS IN THE HEADLIGHT SWITCH CONNECTOR COME INTO CONTACT WITH EACH OTHER CAUSING A SHORT CIRCUIT. NOTE: VEHICLES WITH XENON LOW BEAM HEADLIGHTS ARE NOT AFFECTED BECAUSE THE CIRCUIT IN THESE VEHICLES CONTAINS A FUSE, WHICH PRECLUDES EXCESSIVE CURRENT FLOW IN THE CASE OF A SHORT CIRCUIT.
