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 141 complaints with NHTSA about the 2003 Pontiac Aztek, and it carries 4 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.

Since we first bought the car in 2005, whenever the fuel tank is filled to 3/4 or higher the car starts to smell of fuel fumes. If it is filled up full to the top, it literally spills fuel onto the ground (about 16oz). I

NHTSA lists 4 recall campaigns for the 2003 Pontiac Aztek. 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 VEHICLES, VARIATIONS IN THE MANUFACTURING PROCESS OR EXPOSURE TO HIGH AMBIENT TEMPERATURES MAY LEAD TO FRACTURE OF THE FUEL TANK INLET CHECK VALVE (ICV).
Risk: A FRACTURE MAY ALLOW FUEL VAPORS TO PASS THROUGH AND ALLOW DROPLETS OF FUEL TO ACCUMULATE ON THE SIDE OF THE FUEL TANK. FUEL LEAKAGE, IN THE PRESENCE OF AN IGNITION SOURCE, COULD RESULT IN A FIRE.
Fix: DEALERS WILL REPLACE THE FUEL TANK. THE RECALL WILL BE MAILED IN TWO PHASES WITH THE FIRST PHASE BEGINNING ON DECEMBER 4, 2007. THE SECOND PHASE WILL BE MAILED ON DECEMBER 13, 2007. OWNERS MAY CON

Risk: FUEL MAY LEAK, POSSIBLY RESULTING IN A FIRE.
Fix: DELPHI WILL NOTIFY OWNERS AND REPLACE THE UPR FREE OF CHARGE. THE RECALL BEGAN ON APRIL 23, 2007. OWNERS CAN CONTACT DELPHI AT 877-411-8770.
CERTAIN MINIVANS, PASSENGER AND SPORT UTILITY VEHICLES FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 225, "CHILD RESTRAINT ANCHORAGE SYSTEM." THE OWNER'S MANUAL DOES NOT EXPLAIN THE MEANING OF THE LOCATION SYMBOLS FOR THE CHILD RESTRAINT LOWER UNIVERSAL ANCHORAGE
Risk: THIS DOES NOT MEET THE REQUIREMENTS OF THE STANDARD.
Fix: OWNERS WILL BE PROVIDED WITH A SUPPLEMENT FOR THEIR OWNER'S MANUAL. THIS SUPPLEMENT DESCRIBES AND SHOWS THE LOCATION SYMBOLS FOR THE CHILD RESTRAINT ANCHORS THAT ARE LOCATED IN THE VEHICLE AND ON THE
IN SOME OF THESE SPORT UTILITY VEHICLES, THE DIAMETER OF THE STEERING COLUMN INTERMEDIATE SHAFT IS TOO SMALL.
Risk: THIS CONDITION COULD ALLOW THE INTERMEDIATE SHAFT TO SPIN INSIDE THE STEERING COLUMN COUPLING, RESULTING IN LOSS OF STEERING CONTROL OF THE VEHICLE. IF THIS WERE TO HAPPEN WHILE THE VEHICLE IS MOVING
Fix: DEALERS WILL INSPECT, AND REPLACE IF NECESSARY, THE STEERING COLUMN INTERMEDIATE SHAFT. OWNERS WERE NOTIFIED BY TELEPHONE ON FEBRUARY 7, 2003, WITH A FOLLOW-UP LETTER ON FEBRUARY 11, 2003. OWNERS WH

Percentile ranks against other SUVs in the catalog.
What stands behind each score for this car:
Owners have filed 141 complaints with NHTSA for this model-year, and fuel system is the most reported area with 19 of them (13%). There are 4 recalls on record. Check any specific car against its VIN before buying.
AVOIR scores its reliability 72/100 (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 74/100, 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 67/100. 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.
