Recalls
ON CERTAIN MINIVANS EQUIPPED WITH SECOND-ROW BUCKET SEATS OR CAPTAIN'S CHAIRS AND A POWER SLIDING DOOR ON THE PASSENGER SIDE OF THE VEHICLE, A PASSENGER USING THE INTERIOR HANDLE TO OPEN THE POWER SLIDING DOOR COULD BE INJURED.
ON CERTAIN PASSENGER VEHICLES AND MINI VANS, THE DRIVER'S AIR BAG INFLATOR MODULES COULD PRODUCE EXCESSIVE INTERNAL PRESSURE. IN THE EVENT OF A CRASH THAT WOULD TRIGGER A DRIVER'S AIR BAG DEPLOYMENT, THE INCREASED INTERNAL PRESSURE CAN CAUSE THE INFLATOR MODULE TO EXPLODE.
Whether a recall was fixed on a particular car is known only to the manufacturer: check the VIN at nhtsa.gov/recalls.
