2004 Infiniti Q45 common problems

The most-reported problem areas across all 7 owner complaints filed with NHTSA — and what to check before you buy.

Electrical System
Test every electrical feature: windows, locks, infotainment, charging and all lights. Watch for flickering, dead accessories or warning lights.
Steering
Steering should be tight and centered — no play, clunks or wandering. Test at low and highway speed; listen for power-steering whine.
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.
Exterior Lighting
Confirm all headlights, brake lights, turn signals and reverse lights work, with no moisture inside the housings.
Vehicle Speed Control
Test cruise control and throttle response, and watch for any hesitation or unintended acceleration.
Structure
Inspect for rust, fresh undercoating, mismatched paint, uneven panel gaps and any sign of prior collision or frame repair.
