The 2017 GT-R's VR38DETT is a robust platform when maintained properly, but the dual-clutch transmission and associated cooling systems are its Achilles heel. Track use or aggressive driving accelerates wear dramatically, and major engine work—while rare under stock conditions—becomes inevitable when owners chase power.
Transmission Oil Cooler Failure
Common · high severityTypical onset: 40,000-80,000 mi
Symptoms: Transmission overheating warnings on display, Limp mode activation during spirited driving, Burnt transmission fluid smell, Rough shifts or clutch slippage
Fix: Cooler assembly replacement requires dropping undertray and disconnecting multiple hard lines. 4-6 hours labor. OEM cooler is mandatory—aftermarket units fail faster. Flush and refill transmission fluid while you're in there.
Estimated cost: $1,800-2,800
Transmission Mount Deterioration
Common · medium severityTypical onset: 50,000-90,000 mi
Symptoms: Clunking during hard acceleration or deceleration, Excessive drivetrain movement felt through cabin, Vibration at idle in gear, Misalignment causing premature driveshaft wear
Fix: Rubber mounts crack and separate from metal housing. Replacement requires supporting transmission on jack, removing crossmember bolts. 3-4 hours. Replace both while you're in—they fail together. Upgraded polyurethane mounts add NVH but last longer.
Estimated cost: $900-1,500
Launch Control Clutch Pack Degradation
Occasional · high severitySymptoms: Shuddering during 1-2 or 2-3 shifts, Transmission slipping under load, Delayed engagement from stop, Metal shavings in transmission fluid
Fix: Repeated launch control use cooks the dual-clutch packs. Requires full transmission removal and teardown—16-20 hours labor. Clutch pack replacement, new seals, fluid, and often the mechatronic unit needs cleaning or replacement. This is why low-mileage used GT-Rs scare me.
Estimated cost: $8,000-14,000
Engine Internals Failure (Modified Cars)
Occasional · high severitySymptoms: Rod knock at startup or under load, Metal debris in oil filter, Loss of compression in one or more cylinders, Catastrophic failure with external oil leak
Fix: Stock internals are good to ~600whp. Beyond that, piston rings land, rods bend, and bearings spin. Short block replacement or full rebuild: 40-60 hours. Forged pistons, rods, upgraded bearings, ARP studs, machine work. If buying used, verify tune history and compression test every cylinder.
Estimated cost: $15,000-28,000
Fuel System Contamination / Filter Clogging
Occasional · medium severityTypical onset: 60,000-100,000 mi
Symptoms: Hesitation or stumble during acceleration, Fuel pressure faults logged, Hard starting when hot, Lean condition codes (P0171/P0174)
Fix: In-tank fuel filter clogs with debris, and the high-pressure pumps are sensitive. Filter replacement requires fuel tank drop—8-10 hours labor because of undertray and exhaust removal. Nissan doesn't sell filter separately; sometimes you're buying the whole pump assembly.
Estimated cost: $1,200-2,200
Turbocharger Wastegate Rattle
Occasional · low severityTypical onset: 70,000-120,000 mi
Symptoms: Metallic rattle at idle or light throttle, disappears under boost, No performance loss initially, Can progress to boost control issues
Fix: Wastegate actuator rods wear at the pivot points. Not a failure yet, but irritating and eventually affects boost control. Turbo removal and actuator replacement or rebuild: 10-12 hours for both sides. Many owners live with it until turbo upgrade time.
Estimated cost: $2,500-4,000
Buy a bone-stock, well-documented example with records and prepare for transmission work—skip anything modified unless you have deep pockets for an engine rebuild.
