How the engine fits this car

The higher-output engine option on this FX generation — the same VQ37VHR covered in detail on the G37's page, replacing the earlier VQ35DE used on the base FX35.

Addresses the earlier VQ35's documented timing chain guide concern through the VQ37's revised design.

Infiniti FX37-specific pros and cons

This is about the car itself — for engine-specific failure points, see the dedicated engine page below.

WHAT HOLDS UP WELL

  • VQ37's revised design addresses the earlier VQ35's documented timing chain guide concern
  • Genuinely strong, distinctive performance-oriented SUV character
  • Strong specialist and tuning community knowledge given shared use across Infiniti's lineup
  • Rear-wheel-drive and all-wheel-drive versions both available

WHAT TO WATCH

  • Fuel economy is modest, typical of a performance-oriented V6 SUV
  • Minor oil consumption has been reported on a smaller subset of examples
  • All-wheel-drive versions add drivetrain complexity worth inspecting separately
  • Purchase price runs somewhat higher than the base FX35

Pre-purchase checklist for this generation

Beyond general maintenance history, there's genuinely little engine-specific risk to flag.

If considering an all-wheel-drive version, inspect the additional drivetrain components separately.

Ask for documented oil change history given this engine's high-revving nature.
