2015 NISSAN 370Z

Typical onset: 40,000-80,000 mi

Symptoms: Clutch pedal falls to floor and stays there, Grinding into gear or inability to shift, Clutch fluid leaking internally into bellhousing, Gradual loss of clutch engagement point

Fix: Requires transmission removal to access the internal slave cylinder. Smart owners replace clutch, flywheel, and rear main seal while in there. 8-12 hours labor depending on shop efficiency.

Estimated cost: $1,800-3,200

Typical onset: 60,000-100,000 mi

Symptoms: Blue smoke on startup or hard acceleration, Oil consumption 1 quart per 1,000-2,000 miles, Oil residue on underside of intake plenum, Low oil pressure warnings if neglected

Fix: Gallery gaskets between block halves deteriorate. Requires upper oil pan removal and plenum off. If caught early, gasket replacement suffices (6-8 hours). If run low on oil repeatedly, expect bearing damage requiring short block.

Estimated cost: $1,200-2,000

Typical onset: 50,000-90,000 mi

Symptoms: Rod knock on cold start that quiets when warm, Metal shavings in oil or filter, Sudden catastrophic failure with loss of power, Low oil pressure at idle after spirited driving

Fix: VQ37VHR bearings are marginal under sustained high RPM or track use. Once knock starts, you're looking at crankshaft polishing or replacement, all bearings, and often piston/ring work if debris circulated. 25-35 hours for short block swap or full rebuild.

Estimated cost: $6,500-12,000

Typical onset: 70,000-120,000 mi

Symptoms: Clunking on shifts or during throttle transitions, Excessive shifter vibration, Difficulty getting into first or reverse, Visible cracking or separation of rubber mount

Fix: Manual transmission mount fatigues and collapses. Replacement is straightforward with trans supported. Often done with CSC job if timing aligns. 2-3 hours standalone.

Estimated cost: $300-600

Typical onset: 80,000-130,000 mi

Symptoms: Engine stumble or cut-out during hard cornering below half tank, No-start after sitting with fuel pump whine absent, Hesitation under wide-open throttle, Check engine light with fuel pressure codes

Fix: Factory fuel pump setup starves in corners; enthusiasts install aftermarket surge tanks. Pump failure requires tank drop. 3-4 hours for pump replacement. Add 2-3 hours if installing proper baffle or dual pump setup.

Estimated cost: $800-1,800

Symptoms: Car won't start with steering lock error on dash, Clicking noise from steering column on start attempt, Intermittent starting issues that become permanent, No warning before total failure

Fix: Electronic steering lock motor fails and prevents ignition. Common enough that many owners pre-emptively pull the fuse and disable the system. Dealer replacement is column-out work, 4-6 hours. Many just live with fuse pulled.

Estimated cost: $800-1,400
