The 2016 Fairlady Z (370Z in most markets) with the VQ37VHR is a solid sports car platform, but the 7-speed automatic transmission has known weak points, and the VQ37 suffers from timing chain gallery gasket oil consumption issues that can lead to catastrophic internal damage if neglected.
Timing Chain Gallery Gasket Oil Consumption / Timing System Failure
Common · high severity
Typical onset: 80,000-120,000 mi
Symptoms: Excessive oil consumption (1 qt per 1,000-2,000 mi), Cold start rattle lasting 2-5 seconds from timing chain area, Check engine light with cam/crank correlation codes (P0011, P0021), Metal shavings in oil, engine knock at higher mileage if chain jumped
Fix: Gallery gaskets leak internally, starving timing components of oil. Full timing chain kit replacement with updated gaskets, guides, tensioners, and both chains required. Engine-out service recommended for thorough access and gallery inspection. 18-24 labor hours depending on additional head work if damage occurred.
Estimated cost: $3,500-6,500
7-Speed Automatic Transmission Valve Body / Torque Converter Shudder
Common · medium severity
Typical onset: 60,000-90,000 mi
Symptoms: Harsh 2-3 or 3-4 upshifts, especially when warm, Shudder or vibration during light throttle acceleration 30-50 mph, Delayed engagement into Drive or Reverse after sitting, Transmission overheat warnings on spirited drives
Fix: Valve body solenoids stick, and torque converter lockup clutch wears. Valve body replacement or rebuild plus fluid flush often needed; severe cases require torque converter replacement. 8-12 labor hours for valve body, 14-18 if converter included.
Estimated cost: $2,200-4,800
Fuel System / Fuel Pump Failure
Occasional · high severity
Typical onset: 70,000-110,000 mi
Symptoms: Hard starting after sitting, especially in heat, Stumble or hesitation under hard acceleration, Stalling at idle after highway runs, Fuel pump whine audible from rear seat area
Fix: In-tank fuel pump assembly fails, sometimes related to clogged fuel filter element inside the pump module. Requires drop of fuel tank. 4-6 labor hours including pump assembly and new tank seals.
Estimated cost: $900-1,600
CSC (Concentric Slave Cylinder) Failure - Manual Transmission Only
Common · high severity
Typical onset: 40,000-80,000 mi
Symptoms: Clutch pedal stays on floor or feels spongy, Difficulty shifting into gear, especially 1st and Reverse, Fluid leak visible at bellhousing inspection cover, Complete loss of clutch function
Fix: Internal slave cylinder seals fail, leaking fluid into bellhousing. Requires transmission removal. Most techs replace with OEM or upgraded aftermarket unit and full clutch kit while trans is out. 10-14 labor hours including clutch service.
Estimated cost: $2,000-3,500
Steering Lock Actuator Failure
Occasional · high severity
Symptoms: Car will not start, steering wheel locked, dash shows 'Key System Error', Clicking noise from steering column when turning key or pushing start button, Intermittent no-start requiring multiple key cycles, Fails more often in hot weather or after short trips
Fix: Electronic steering lock actuator behind the column fails, preventing ignition. Replacement requires column disassembly and actuator replacement or, commonly, a permanent delete kit to bypass the system. 3-5 labor hours for OEM replacement, 2-3 for delete kit install.
Estimated cost: $800-1,400
Differential Bushing Wear / Clunking
Occasional · low severity
Typical onset: 60,000-100,000 mi
Symptoms: Clunk from rear on throttle tip-in or lift-off, Vibration through chassis during acceleration, Visible movement of differential housing under load, Worn rubber visible on differential mount bushings
Fix: Rear subframe and differential mount bushings wear, allowing excessive movement. Replace all subframe bushings and differential mounts as a set. 4-6 labor hours with alignment check afterward.
Estimated cost: $700-1,200
Owner tips
Check oil level every 500 miles — VQ37 oil consumption is normal up to a point, but anything over 1 qt per 3,000 mi suggests gallery gasket issues brewing.
If buying used, listen for cold-start timing chain rattle and inspect oil cap/filler for sludge; these engines need quality oil and 5,000-mile OCIs maximum.
Manual transmission cars: budget for CSC replacement as preventive maintenance around 50k-60k if not already done; it's not if, but when.
7AT cars: confirm transmission fluid has been serviced every 30k-40k with OEM Nissan Matic-S fluid; aftermarket fluids cause valve body issues.
Steering lock actuator: many owners proactively install a delete kit to avoid being stranded; consider this on any used purchase.
Great driving dynamics and the VQ37 sounds fantastic, but budget $3k-5k for deferred timing chain work or transmission repairs on higher-mileage examples — buy one with service records or walk away.
