The 2017 370Z with the VQ37VHR is a solid enthusiast platform, but high-performance driving and oil starvation issues lead to catastrophic engine failures more often than typical sports cars. Transmission cooling and mount wear are also common pain points.
Oil Starvation and Engine Failure (VQ37VHR)
Occasional · high severityTypical onset: 40,000-80,000 mi
Symptoms: Rod knock or bearing noise during cold starts or hard cornering, Low oil pressure warning under sustained high-G turns, Complete engine seizure after track days or spirited canyon runs, Metal debris in oil filter after teardown
Fix: The VQ37 oil pickup design starves under high lateral G-forces, especially with oil below full mark. Requires full engine rebuild (pistons, rings, bearings, crankshaft machining) or short block replacement. 25-35 labor hours for rebuild, 18-22 for short block swap.
Estimated cost: $8,000-15,000
Transmission Oil Cooler Failure
Common · high severityTypical onset: 60,000-100,000 mi
Symptoms: Milky or strawberry-colored transmission fluid (coolant contamination), Overheating transmission temp gauge readings, Harsh or delayed shifts after fluid contamination, Coolant loss with no visible external leaks
Fix: Internal transmission cooler in radiator fails, allowing coolant and ATF to mix. Requires radiator replacement, complete transmission fluid flush (multiple exchanges), and often transmission rebuild if contamination ran long. 4-6 hours for cooler/flush, add 12-18 if transmission needs internal work.
Estimated cost: $1,200-5,500
Transmission Mount Failure
Common · medium severityTypical onset: 50,000-90,000 mi
Symptoms: Clunking when shifting from reverse to drive or during hard acceleration, Excessive drivetrain movement visible from engine bay, Vibration through shifter and center console, Clicking noise during throttle on/off transitions
Fix: Transmission mount rubber deteriorates quickly, especially with performance driving. Replacement is straightforward but requires supporting the transmission. 2-3 labor hours.
Estimated cost: $400-700
Fuel System Clogging and Starvation
Occasional · medium severityTypical onset: 70,000-120,000 mi
Symptoms: Fuel pump whine or buzzing louder than normal, Hesitation or stumble under wide-open throttle above 5,000 RPM, Intermittent rough idle or lean codes (P0171/P0174), Low fuel pressure readings during diagnostics
Fix: In-tank fuel filter screens and pump pre-filters clog with sediment. Fuel pump assembly or full tank drop required for access. Some owners report filter isn't serviceable separately, requiring pump replacement. 3-4 labor hours for tank drop and pump service.
Estimated cost: $600-1,200
Concentric Slave Cylinder Failure (Manual)
Occasional · medium severityTypical onset: 60,000-100,000 mi
Symptoms: Clutch pedal staying on floor after depression, Difficulty engaging gears with clutch pedal down, Gradual loss of clutch feel or engagement point, Transmission fluid leak visible at bell housing
Fix: The internal CSC (concentric slave cylinder) fails and leaks into the bell housing. Requires transmission removal. Smart shops replace with upgraded aftermarket unit. 8-10 labor hours with clutch inspection.
Estimated cost: $1,400-2,200
Steering Lock Module Failure
Occasional · high severitySymptoms: Push-button start system won't engage, "Steering Lock Malfunction" warning, Complete no-start condition despite good battery, Clicking sound from steering column when attempting start, Intermittent failures that become permanent
Fix: Electronic steering lock motor fails and physically locks steering, preventing start. Common enough that many owners preemptively pull the fuse. Nissan TSB exists. 2-3 labor hours for column disassembly and module replacement.
Estimated cost: $500-900
Buy it if you understand the oil starvation risk and budget for preventive measures or avoid track use—otherwise it's a grenade with the pin half-pulled for enthusiast drivers.
