Infiniti QX50

The name covers two mechanically opposite cars. To 2017 the QX50 is the renamed EX35 and EX37: rear-drive-based, longitudinal VQ V6, and diagnostically an Infiniti G-series with a different body — so G37 and 370Z information applies. From 2019 it is transverse, front-drive-based and carries the VC-Turbo, the production variable-compression engine, which is the reason to read the year first. That engine has a multilink mechanism and an electric actuator that continuously changes the compression ratio, with its own position sensor and control strategy, so it can set faults no other four-cylinder can — and a compression test on it does not mean what it means elsewhere. The CVT behind it is a Jatco unit with the usual fluid-temperature sensitivity.

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.
