Nissan 370z Problems: Common Issues and Repair Costs
The Nissan 370Z is a fan-favorite among sports car enthusiasts. With its powerful V6 engine, sharp handling, and bold styling, it’s easy to see why. But like any performance car, the 370Z comes with some common issues that owners or buyers should be aware of. In this guide, we’ll go through the most frequent Nissan 370Z problems, what to look for, and how much they cost to repair in the UK.
1. Clutch Slave Cylinder Failure
What happens:
Many 370Zs suffer from clutch slave cylinder (CSC) issues, especially older models from 2009 to 2014. The CSC is located inside the gearbox, so replacing it involves removing the transmission, which means high labour costs.
Symptoms:
- Spongy or sinking clutch pedal
- Clutch doesn’t return properly
- Fluid leaks near the gearbox
Repair cost in the UK:
- Parts: £150 to £250
- Labour: £500 to £700
- Total: £650 to £950
If you’re replacing this part, it’s wise to change the clutch and flywheel at the same time to avoid future labour costs.
2. Steering Lock Module Failure
What happens:
Early 370Z models (2009 to 2012) often suffer from a failed electronic steering lock, which stops the car from starting. This was part of a recall in the US, but not all UK vehicles were covered.
Symptoms:
- Car doesn’t start
- Steering lock light on the dashboard
- Clicking noise from the steering column
Repair cost in the UK:
- OEM parts: £400 to £600
- Labour: £80 to £150
- Bypass kit option: £60 plus fitting
- Total: £140 to £750
Most owners now choose the bypass kit, which disables the steering lock permanently and avoids future failure.
3. High Oil Consumption and Heat Issues
What happens:
The VQ37VHR engine is strong but can consume oil quickly, especially if driven hard. High oil temperatures are another common issue, which is why many owners fit aftermarket oil coolers.
Symptoms:
- Frequent low oil readings
- Burning oil smell
- High oil temperature on dashboard
Repair cost in the UK:
- Aftermarket oil cooler: £300 to £500
- Installation: £150 to £250
- Engine rebuild (if ignored): £2,500 to £6,000
- Total: £450 to £750 (preventive)
Check oil monthly and top up with the correct grade to avoid engine damage.
4. Gearbox Synchro Wear
What happens:
Manual 370Zs often develop synchro wear in 2nd and 3rd gear, especially after 60,000 miles. This is caused by aggressive shifting or poor gearbox oil maintenance.
Symptoms:
- Crunching when shifting gears
- Stiff gear engagement
- Grinding sound
Repair cost in the UK:
- Rebuild or used gearbox: £1,000 to £2,000
- Labour: £400 to £600
- Total: £1,400 to £2,600
Early signs can be reduced with a gearbox oil flush and additive, but that only delays the inevitable.
5. Hatch Doesn’t Pop Open
What happens:
A common but minor annoyance. Over time, the hatch struts wear out and don’t provide enough force to pop the boot open.
Symptoms:
- Boot doesn’t lift on its own
- Must pull it open manually
Repair cost in the UK:
- New struts: £30 to £60
- DIY fitting or garage: £20 to £40
- Total: £50 to £100
6. Exhaust Fumes in the Cabin
What happens:
Some 370Z owners notice a strong exhaust smell inside the cabin. This is usually due to worn rear hatch seals or failing exhaust gaskets.
Symptoms:
- Smell of fumes while driving
- Black soot around the bumper
- Headaches or nausea during longer drives
Repair cost in the UK:
- Seals and gaskets: £50 to £100
- Labour: £100 to £200
- Total: £150 to £300
7. Timing Chain Rattle
What happens:
Rare, but high-mileage cars can suffer from a rattling timing chain caused by worn tensioners. It usually starts as a noise during cold starts and can get worse over time.
Symptoms:
- Rattling when starting the car
- Engine warning light
- Reduced performance
Repair cost in the UK:
- Parts: £400 to £700
- Labour: £600 to £900
- Total: £1,000 to £1,600

Final Advice for Buyers and Owners
