How do you know if your vehicle is currently under a National Highway Traffic Safety Administration (NHTSA) recall? You can wait for a notification letter to arrive by mail but the easiest way is to log onto the NHTSA website and do a VIN search. That'll tell you for sure. Have your vehicle identification number and production date (located inside the driver door jamb on most models) handy; this information will make it easier to determine whether or not your ride is under a NHTSA recall.
