2015 Infiniti q40 common problems

The most-reported problem areas across all 8 owner complaints filed with NHTSA — and what to check before you buy.

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.
Structure
Inspect for rust, fresh undercoating, mismatched paint, uneven panel gaps and any sign of prior collision or frame repair.
Electronic Stability Control (esc)
Have a trusted mechanic inspect this system as part of a pre-purchase inspection.
