Reliability, what owners report, and what it costs to keep.
AVOIR's read: the numbers are mixed and the complaint record is worth reading before you commit.
Owners have filed 883 complaints with NHTSA about the 2003 Nissan Altima, and it carries 10 recalls. These are owner allegations rather than confirmed defects, but the pattern of what people complain about is the most useful signal a used buyer has.

What stands behind each score for this car:
Owners have filed 883 complaints with NHTSA for this model-year, and engine and engine cooling is the most reported area with 384 of them (43%). There are 10 recalls on record. Check any specific car against its VIN before buying.
AVOIR scores its reliability 48/100 (below average) from NHTSA recall campaigns and complaint density, adjusted for how many were sold so a popular model is not penalised for having more owners.
AVOIR scores its longevity 63/100, but that figure is an estimate built from the powertrain and the brand's record, not a measurement. A 2003 car has no 200,000-mile population to observe yet, so treat it as a prior rather than evidence.
AVOIR's read: be careful, because the numbers are mixed and the complaint record is worth reading before you commit. Its overall ownership score is 62/100. Condition, mileage and service history still matter more than any score, so get a pre-purchase inspection on the specific car.
Sources: NHTSA recalls and complaints, EPA fuel economy, IIHS awards, and live market listings. A score describes a model-year, not the individual car in front of you. Get a pre-purchase inspection.
