Infiniti is Nissan's luxury division — the G/Q-series sedans (G35, G37, Q50, Q60), the QX SUVs (QX50, QX60, QX80), and the FX/QX70 share platforms and parts catalogs with their Nissan counterparts. The VQ-series V6 (3.5L / 3.7L) is the most common drivetrain we see, and it has its own service profile alongside the platform-specific items Nissan-built vehicles bring with them. Frank's Automotive in Seguin services Infiniti with Nissan-platform diagnostic capability.
Infiniti issues we see most often
Infiniti patterns overlap with Nissan plus some luxury-tech items:
- VVEL (Variable Valve Event and Lift) actuator issues on VQ37VHR (G37, Q50, Q60, FX37) — misfire, rough running, sometimes metallic noise
- Timing chain stretch on VQ37 engines at high mileage
- CVT transmission issues on Q50, QX50, QX60 (CVT-equipped) — same patterns as Nissan: shudder, hesitation; fluid service is critical
- VQ-series oil consumption on some years — worth documenting if you're seeing it
- Catalytic converter failures (similar pattern to Altima 2.5L on shared-engine Infiniti models)
- Air suspension on FX / QX70 / QX80 — compressor or air-spring failure
- InfinitiConnect / electronics glitches — battery drain from telematics, infotainment reboots
