10.3% of complaints about the 2003 Pontiac Aztek came in the first year, which is unremarkable for a 2003 vehicle — around the middle of the 228 model-years on record. The median complaint arrives at 3.9 yr in service. The most-reported system is electrical system (28 complaints), typically at 6.9 yr or about 76,000 miles.
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).
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.
CERTAIN DELPHI FUEL PRESSURE REGULATORS, P/NOS. FP10020-11B1, FP10026-11B1, AND FP10027-11B1, SOLD AFTER JANUARY 9, 2007, AS AFTERMARKET EQUIPMENT FOR VARIOUS PASSENGER VEHICLES LISTED ABOVE. THE UNIVERSAL PRESSURE REGULATORS (UPR) WERE PRODUCED WITHOUT AN O'RING AND RETAINER.

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 SYSTEM.
THIS DOES NOT MEET THE REQUIREMENTS OF THE STANDARD.
IN SOME OF THESE SPORT UTILITY VEHICLES, THE DIAMETER OF THE STEERING COLUMN INTERMEDIATE SHAFT IS TOO SMALL.
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, A CRASH COULD RESULTING WITHOUT PRIOR WARNING.
