NHTSA lists 2 recall campaigns for the 1998 Infiniti I30. 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.
ON CERTAIN PASSENGER VEHICLES, ONE OF THE DIODES USED IN THE ALTERNATOR MAY HAVE BEEN DAMAGED WHEN BUILT. THIS CAN EVENTUALLY RESULT IN FAILURE OF THE DIODE AND AN ELECTRICAL SHORT WHICH COULD MELT THE PLASTIC HOUSING.
Risk: IF THE COMBUSTIBLE GAS EMITTED BY THE MELTING PLASTIC DOES NOT DISPERSE DUE TO AIR FLOW THROUGH THE ENGINE COMPARTMENT, IT COULD IGNITE AND IN TURN IGNITE THE FAN GUIDE IN THE ALTERNATOR.
Fix: DEALERS WILL REPLACE THE ALTERNATOR. OWNER NOTIFICATION BEGAN JULY 29, 2002. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY

What stands behind each score for this car:
Owners have filed 54 complaints with NHTSA for this model-year, and air bags is the most reported area with 20 of them (37%). There are 2 recalls on record. Check any specific car against its VIN before buying.
AVOIR scores its reliability 90/100 (excellent) 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 82/100, but that figure is an estimate built from the powertrain and the brand's record, not a measurement. A 1998 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.
