Recalls
CERTAIN PASSENGER VEHICLES FAIL TO CONFORM TO THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 208, 'OCCUPANT CRASH PROTECTION.' THE BILINGUAL ENGLISH/SPANISH REMOVABLE AIR BAG WARNING LABELS AFFIXED TO THE DASH AND TO THE SUNVISOR DO NOT MEET THE SIZE REQUIREMENTS OF THE STANDARD.
CERTAIN SPORT UTILITY AND PASSENGER VEHICLES FAIL TO COMPLY WITH FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 225, "CHILD RESTRAINT ANCHORAGE SYSTEMS." THE OWNER'S MANUAL DOES NOT CONTAIN A STEP-BY-STEP DESCRIPTION FOR HEADREST ADJUSTMENT WHEN INSTALLING A CHILD RESTRAINT SYSTEM (CRS) TETHER STRAP.
ON CERTAIN PASSENGER VEHICLES, THE MAIN UNDER HOOD ELECTRICAL WIRING HARNESS MAY HAVE INSUFFICIENT CLEARANCE BETWEEN THE ENGINE CONTROL HARNESS AND THE EXHAUST HEAT SHIELD. AS A RESULT, THE HARNESS COULD COME IN CONTACT WITH THE HEAT SHIELD, WHICH COULD RESULT IN MELTING OF THE HARNESS INSULATION.
Whether a recall was fixed on a particular car is known only to the manufacturer: check the VIN at nhtsa.gov/recalls.
