2013 NISSAN GT-R

Typical onset: 40,000-80,000 mi

Symptoms: harsh shifts or clunking during gear changes, transmission overheating warnings on display, loss of gears or stuck in limp mode, metallic debris in transmission fluid during service

Fix: Transmission requires removal for clutch pack replacement or full rebuild. Expect 18-24 hours labor for clutch service, 30+ hours for complete rebuild. OEM clutch packs are mandatory; aftermarket often fails prematurely. Cooler line upgrades recommended during reinstallation.

Estimated cost: $5,000-12,000

Typical onset: 60,000-100,000 mi

Symptoms: metallic knocking or ticking on cold start that worsens with RPM, oil pressure drop or fluctuation, metal shavings in oil filter during changes, catastrophic engine failure if ignored

Fix: Full engine teardown required. Crankshaft, main bearings, and rod bearings typically replaced together. Expect 40-50 hours labor for complete bottom-end rebuild. Machine work for crank journals often needed. Many owners upgrade to forged internals at this point.

Estimated cost: $15,000-25,000

Typical onset: 70,000-120,000 mi

Symptoms: white smoke from exhaust on startup, coolant loss with no visible leaks, oil and coolant mixing (milky oil or oil in coolant), misfires or rough idle as gasket degrades

Fix: Heads must be removed, inspected for warping, and resurfaced if needed. Head studs recommended over stock bolts for longevity. 20-28 hours labor per bank. If both banks are leaking, many shops recommend doing both simultaneously.

Estimated cost: $4,500-8,000

Typical onset: 50,000-90,000 mi

Symptoms: transmission fluid puddles under vehicle, burnt transmission fluid smell, transmission overheating warnings, visible fluid weeping from hard lines or fittings

Fix: Hard lines crack from heat cycling and vibration. Front undertray and bumper removal required for access. 4-6 hours labor. OEM lines recommended; aftermarket braided alternatives available for track cars. Replace all lines simultaneously to prevent comebacks.

Estimated cost: $800-1,500

Typical onset: 80,000-130,000 mi

Symptoms: rough idle or misfires under load, fuel trims way off (rich or lean), check engine light with injector flow codes, hard starting or extended cranking when hot

Fix: Injectors clog or fail; pump output drops with age. Injector replacement requires intake manifold removal, 8-12 hours labor for all six. Fuel pump access is easier (3-4 hours) but requires tank drop. Use OEM or quality aftermarket (Injector Dynamics) only.

Estimated cost: $2,000-4,500

Typical onset: 40,000-70,000 mi

Symptoms: clunking during hard acceleration or deceleration, excessive driveline vibration at idle, visible cracking or tearing of rubber mount, transmission movement visible during launch control

Fix: Single rear transmission mount fails from repeated launch control abuse. 2-3 hours labor with lift access. Upgrade to polyurethane or solid mounts common for performance use but increases NVH. OEM rubber acceptable for street cars.

Estimated cost: $400-800

Symptoms: sudden loss of compression in one or more cylinders, excessive blowby and crankcase pressure, blue smoke under load, catastrophic if detonation occurs

Fix: Almost exclusive to cars with sustained track use or aggressive tuning. Piston ring lands crack from detonation or sustained high load. Requires complete short-block replacement or forged piston upgrade. 35-45 hours labor.

Estimated cost: $12,000-20,000
