| Engine | 55 | 15% | |
| Electrical System | 46 | 12% | |

Service Brakes
104 of the 358 complaints (29%) mention brakes. Brake complaints turn up on nearly every vehicle, and Phoenix stop-and-go traffic wears brake parts quickly. We measure pads and rotors, check calipers and fluid, and replace only what is worn. See our brake repair page.
Engine
55 of the 358 complaints (15%) 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.
Electrical System
46 of the 358 complaints (12%) 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.

Most Common Infiniti QX56 Check Engine Codes
Owners often put the exact trouble code in their NHTSA complaint. These are the codes cited most often for the QX56. The most-cited is C1179 (manufacturer-specific chassis code), mentioned in 4 complaints. Counts reflect complaints that name a code, not every car on the road.
| Code | What it means | Complaints citing it |
|---|---|---|
| C1179 | Manufacturer-specific chassis code The meaning of this code varies by make and model, so it needs to be looked up for your vehicle and tested. | 4 |
| P0011 | Intake camshaft timing over-advanced (bank 1) Often an oil, variable valve timing solenoid or timing component issue. Low or dirty oil is a common trigger. | 2 |
| P0300 | Random or multiple cylinder misfire Worn spark plugs, failing ignition coils, fuel or vacuum problems. Do not ignore a flashing check engine light. | 2 |
A code is a clue, not a diagnosis. The same code can have several causes, so we test before replacing parts. See our check engine light diagnostics, and read whether it is safe to drive with the check engine light on.

Keeping a Infiniti QX56 Reliable in Phoenix
Arizona heat is the hardest test a Infiniti will face. Batteries, belts, hoses, tires and engine oil all wear faster here, and a QX56 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 QX56 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 Infiniti QX56, a pre-purchase inspection shows what the paperwork does not.
