2005 Infiniti Q45 common problems

The most-reported problem areas across all 4 owner complaints filed with NHTSA — and what to check before you buy.

Vehicle Speed Control
Test cruise control and throttle response, and watch for any hesitation or unintended acceleration.
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.
Seats
Have a trusted mechanic inspect this system as part of a pre-purchase inspection.
Tires
Check tread depth, the DOT age date, and that all four tires match with even wear. Look for bulges or cracks.
Electrical System
Test every electrical feature: windows, locks, infotainment, charging and all lights. Watch for flickering, dead accessories or warning lights.
