2004 Infiniti QX56 common problems

The most-reported problem areas across all 106 owner complaints filed with NHTSA — and what to check before you buy.

Service Brakes
Brakes should feel firm and quiet — no grinding, pulsing or pulling. Check for an ABS light and uneven pad/rotor wear.
Hydraulic
Have a trusted mechanic inspect this system as part of a pre-purchase inspection.
Electrical System
Test every electrical feature: windows, locks, infotainment, charging and all lights. Watch for flickering, dead accessories or warning lights.
Air Bags
Confirm the airbag light turns on then off at startup — if it stays lit there's a fault (costly, and a safety risk). Check for signs of prior deployment.
Engine
Listen for knocks or ticking, check for leaks and blue/white exhaust smoke, and make sure it doesn't overheat. No check-engine light should be on.
Visibility
Test wipers, washers, defrosters and all mirrors. Check the windshield for cracks and any camera/sensor for fogging or faults.

Engine

On certain vehicles the Intelligent Power Distribution Module (IPDM) assembly contains an Engine Control Module (ECM) relay that has a diode for electrical current noise reduction. The ECM relay may allow silicon vapor to form and over time the silicon evaporates from the diode molding which causes silicon oxide to develop on the ECM relay contact due to arcing. In certain inst…

Electrical

Certain 2005-2006 model year vehicles may have been assembled with an incorrectly manufactured air conditioning condenser fan motor, which could allow excessive water intrusion and inadequate drainage. If sufficient moisture accumulates in the motor, corrosion could occur, increasing internal friction, and thereby augmenting the electrical current draw. This could cause an incr…
