NHTSA lists 5 recall campaigns for the 2004 Hyundai Elantra. Recalls are free to have fixed at a franchised dealer regardless of who owns the car now, but only if they were never done, so check the VIN of the specific car rather than trusting the model.
DURING AN INSURANCE INSTITUTE FOR HIGHWAY SAFETY (IIHS) OFFSET FRONTAL BARRIER IMPACT TEST, IT WAS DETERMINED THAT FUEL TAN DAMAGE COULD OCCUR. ON CERTAIN PASSENGER VEHICLES, A VAPOR TUBE HOSE CLAMP THAT IS LOCATED NEAR THE FUEL TANK MAY NOT BE POSITIONED PROPERLY AND COULD CAUSE FUEL LEAKAGE.
Risk: FUEL LEAKAGE IN THE PRESENCE OF AN IGNITION SOURCE MAY RESULT IN A FIRE.
Fix: DEALERS WILL INSPECT THE POSITION OF THE VAPOR TUBE HOSE CLAMP EARS AND CORRECTLY POSITION THE CLAMP, IF NECESSARY. THE RECALL BEGAN ON OCTOBER 5, 2004. OWNERS SHOULD CONTACT HYUNDAI DE PUERTO RICO
CERTAIN VEHICLES EQUIPPED WITH AN ADVANCED AIR BAG SYSTEM. THE OCCUPANT CLASSIFICATION SYSTEM (OCS) INSTALLED IN THE RIGHT FRONT SEAT OF THE VEHICLE MAY MISCLASSIFY A CHILD RESTRAINT SEAT (CRS) AS AN ADULT. THIS MAY OCCUR IF THE CRS IS INSTALLED AFTER AN ADULT HAS BEEN SEATED IN THE RIGHT FRONT
Risk: THE POSSIBILITY OF MISCLASSIFICATION OF A CRS AS AN ADULT MAY ALLOW THE RIGHT FRONT AIRBAG OR SIDE IMPACT AIRBAG TO DEPLOY IN A CRASH AND COULD RESULT IN INJURY TO THE RIGHT FRONT OCCUPANT.
Fix: DEALERS WILL REPROGRAM THE VEHICLE'S OCS ELECTRONIC CONTROL UNIT (ECU) TO REMOVE THE FEATURE THAT MAY CAUSE THE CRS TO BE RECOGNIZED AS AN ADULT. THE RECALL BEGAN ON NOVEMBER 15, 2005. OWNERS MAY C

ON CERTAIN VEHICLES, IF THE FRONT PASSENGER SEAT IS UNOCCUPIED OR IS OCCUPIED BY SOMEONE LIGHTER THAN 56.4 POUNDS, THE PASSENGER AIR BAG IS DEACTIVATED AND WILL NOT DEPLOY IF A CRASH OCCURS. HOWEVER, THE OCCUPANT CLASSIFICATION SENSOR MAY INCORRECTLY INTERPRET THAT A SEATED ADULT IS AN INFANT SEAT
Risk: IN THE EVENT OF A VEHICLE CRASH, THE AIR BAG MAY NOT DEPLOY, POSSIBLY RESULTING IN SERIOUS INJURY TO THE RIGHT FRONT PASSENGER.
Fix: THE OCCUPANT CLASSIFICATION SENSOR WILL BE REPROGRAMMED.

What stands behind each score for this car:
Owners have filed 182 complaints with NHTSA for this model-year, and air bags is the most reported area with 107 of them (59%). There are 5 recalls on record. Check any specific car against its VIN before buying.
AVOIR scores its reliability 74/100 (good) from NHTSA recall campaigns and complaint density. That figure is a raw complaint count, not yet adjusted for sales volume, so a high-volume model scores worse than it deserves.
AVOIR scores its longevity 76/100, but that figure is an estimate built from the powertrain and the brand's record, not a measurement. A 2004 car has no 200,000-mile population to observe yet, so treat it as a prior rather than evidence.
AVOIR's read: worth a look, because a solid ownership case with specific caveats below. Its overall ownership score is 72/100. Condition, mileage and service history still matter more than any score, so get a pre-purchase inspection on the specific car.
