Infiniti Q70
The large rear-drive saloon, renamed from M to Q70 in 2014 — the same car, and the older name is where most of its written history sits. It is the Nissan Fuga in Japan and shares the FM platform with the Q50 and 370Z, so those pages cover much of the driveline. The VQ37VHR V6 is the engine most carry, and its variable valve event and lift system on the intake side is the part that generates unfamiliar codes. The VK56 V8 cars use the same exhaust-manifold and precatalyst arrangement as the Titan, so a lean code with healthy fuelling is worth investigating upstream before the fuel system. Air suspension on some trims sets its own ride-height faults.
Generations

Y33 (M45) 2002–2004
The first M in North America — a rebadged **Nissan Gloria** with the 4.5 VK45DE V8 dropped in, sold for two model years only and in small numbers. Mechanically it belongs with the Q45 of the same years rather than with the M35 that followed.

Y50 2004–2010
Sold as **M35 and M45**, and in Japan as the Nissan Fuga. On the FM platform shared with the G35 and the 350Z, so its front suspension and much of its drivetrain read across from those cars.

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
