Common Problems Nissan 370Z

The Z is a classic sports car with generations spanning for decades. As with any vehicle, each generation has common issues, and in this article, we review the signs, causes, and fixes for the most common problems with the 6th generation Nissan 370Z, years 2009-2020.

Top 5 Issues 6th Gen Nissan 370Z (2009-2020)

1. Concentric Slave Cylinder (CSC) Failure

Symptoms of CSC Failure

Hose/line and bleeder valve on driver side of 370z transmission where clutch fluid may leak
Line and bleeder valve on driver side of transmission where clutch fluid may leak
  • Clutch pedal stays depressed and 370Z won’t go into gear after trying to shift
  • Sometimes the 370Z doesn’t pull out of gear when driving
  • If the two symptoms above occur, the brake master cylinder and clutch reservoir will be low on fluid and probably leaking underneath. Clutch fluid might be leaking outside of the driver side of the transmission housing, near the hose and bleeder valve, where the slave cylinder is located.

Causes of CSC Failure

Concentric slave cylinder failure on the Nissan 370Z is usually caused by low or leaking clutch fluid, which can wear out parts and create other problems like a worn clutch.

How to Fix CSC Failure

  • If the slave cylinder is broken and needs replacing, the clutch likely needs to be replaced and the flywheel likely needs to be resurfaced and replaced. Consider replacing the bad slave cylinder with a heavy duty slave cylinder
  • Sometimes a clutch fluid flush will fix CSC failure on the 09-20 Z. Refill the system with DOT 4 clutch fluid because it has a better temperature rating for the transmission than the DOT 3 fluid inside

Clicking sound from the rear wheel when it is turning

How to Fix Steering Wheel Lock

  • A potential temporary fix to unlock the steering wheel is to tap the ESCL module for a few times with a solid object like a smart phone.
  • A long-term fix is to replace the ESCL module

5. High Oil Consumption

Symptoms of High Oil Consumption

Engine ticking/knocking, especially when accelerating

Causes of 370Z High Oil Consumption

Low oil level causes high oil consumption. If the oil level is not low, see if the engine is near the oil change interval

How to Fix High Oil Consumption

  • Adding a little engine oil might help reduce the ticking noise if the 370Z is not due for an oil change soon
  • If the 370Z is under warranty, the dealer can run an oil consumption test to see how much is consumed by mileage over time. The 370Z will most likely get a new engine small block if it’s within the expectations
  • If the 370Z is not under warranty, try installing an oil catch can and keep up with oil change intervals
