2018 Infiniti QX80 common problems

The most-reported problem areas across all 8 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.
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.
Exterior Lighting
Confirm all headlights, brake lights, turn signals and reverse lights work, with no moisture inside the housings.
Steering
Steering should be tight and centered — no play, clunks or wandering. Test at low and highway speed; listen for power-steering whine.
Communication
Have a trusted mechanic inspect this system as part of a pre-purchase inspection.
Seat Belts
Check that every belt latches, retracts and locks under a sharp tug, and that none are frayed.
