Electrical System
9 of the 34 complaints (26%) mention the electrical system. Electrical problems are made worse by desert heat, which ages batteries, cables and connectors. We test the battery, starter and charging system and trace faults to the actual part. See our battery replacement and starter & alternator repair pages.
Engine
4 of the 34 complaints (11%) mention the engine and cooling system. Engine and cooling complaints are best caught early in Phoenix, where heat pushes cooling systems and engine oil to their limits. We diagnose warning lights and check coolant, hoses and oil condition. See our check engine light diagnostics and oil change & maintenance pages.
Fuel System, Gasoline
4 of the 34 complaints (11%) mention the fuel system. Fuel system problems can cause stalling, hard starts and poor mileage. We test fuel delivery and related sensors to find the real cause. See our no-start diagnostics and check engine light diagnostics pages.
Pontiac Aztek Check Engine Codes
NHTSA owner complaints rarely cite specific trouble codes for the Aztek, so we do not have a model-specific ranking to show. These are the check engine codes we see most often on vehicles in Phoenix heat, and any of them can show up on a Pontiac.
| Code | What it means |
|---|---|
| P0420 | Catalyst efficiency below threshold (bank 1) Often a worn catalytic converter, but failing oxygen sensors or exhaust leaks can set it too. Can cause an emissions test failure. |
| P0300 | Random or multiple cylinder misfire Worn spark plugs, failing ignition coils, fuel or vacuum problems. Do not ignore a flashing check engine light. |
| P0171 | System too lean (bank 1) Often a vacuum leak, dirty MAF sensor, weak fuel delivery or a failing oxygen sensor. |
| P0455 | EVAP system large leak Missing or loose gas cap, or a disconnected or cracked vapor hose. |
| P0128 | Coolant temperature below thermostat regulating temperature Usually a thermostat stuck open. Fix it to restore efficiency and cabin heat. |
| P0442 | EVAP system small leak Loose or worn gas cap, cracked hose or purge or vent valve. |
| P0301 | Cylinder 1 misfire Commonly a bad spark plug or ignition coil on that cylinder. |
| P0401 | EGR flow insufficient Clogged EGR passages or a stuck EGR valve. |

Keeping a Pontiac Aztek Reliable in Phoenix
Arizona heat is the hardest test a Pontiac will face. Batteries, belts, hoses, tires and engine oil all wear faster here, and a Aztek that spends its life in stop-and-go Valley traffic needs maintenance earlier than the owner's manual's normal schedule suggests.
Our recommendation for Aztek owners: follow the severe-service schedule, test the battery before every summer, inspect brakes and tires twice a year, and have any warning light diagnosed instead of ignored. If you are shopping for a used Pontiac Aztek, a pre-purchase inspection shows what the paperwork does not.
