The 2012 370Z with its VQ37VHR engine is a solid sports car platform, but suffers from a notorious oil consumption defect tied to piston ring issues, plus CSC (concentric slave cylinder) failures on manuals that can leave you stranded.
VQ37VHR Oil Consumption / Piston Ring Failure
Common · high severity
Typical onset: 60,000-100,000 mi
Symptoms: Excessive oil consumption (1 qt per 500-1,000 miles), Blue smoke from exhaust on startup or acceleration, Fouled spark plugs, Loss of power, Check engine light with misfire codes
Fix: Galley gasket and piston ring design flaw causes oil to pool and carbon up rings. Proper fix requires engine-out teardown, new pistons/rings, honing, valve seals, timing components. 25-35 hours labor. Some attempt top-end refresh but compression loss often mandates full rebuild or short block swap.
Symptoms: Clutch pedal stays to floor, Grinding into gear or inability to shift, Clutch fluid leak inside bellhousing, Soft or spongy clutch pedal feel
Fix: Internal slave cylinder fails, leaks fluid into bellhousing. Requires transmission drop to access. 8-12 hours labor. Smart owners replace with upgraded aftermarket CSC and clutch line at same time. If doing clutch anyway, add 2-3 hours.
Estimated cost: $1,200-2,200
Fuel Starvation / Fuel System Issues Under High-G Loads
Occasional · medium severity
Symptoms: Engine stumble or cut-out during hard cornering or track use, Hesitation when fuel level below half tank, Limp mode activation during spirited driving
Fix: Factory fuel pump setup and baffling inadequate for sustained lateral G. Not catastrophic for street use, but track rats see it regularly. Aftermarket fuel starve kit or upgraded pump assembly solves it. 3-5 hours labor for pump/sender work.
Estimated cost: $800-1,500
Transmission Oil Cooler and Differential Fluid Overheating
Common · medium severity
Symptoms: Transmission or diff goes into limp mode in hot weather or spirited driving, Burnt transmission fluid smell, Harsh shifts when hot, Diff whine increasing with temperature
Fix: Factory cooling marginal, especially on automatics and in warm climates. Aftermarket trans and diff coolers recommended for any performance use. Installation 4-6 hours depending on setup. Fluid flush adds 1 hour.
Estimated cost: $600-1,200
Steering Lock Actuator Failure
Occasional · high severity
Typical onset: 50,000-90,000 mi
Symptoms: Car won't start, steering wheel locked, No crank, dash lit but ignition won't engage, Intermittent no-start requiring multiple key cycles
Fix: Electronic steering lock motor fails, prevents starting entirely. Nissan part expensive and fails again. Most techs pull fuse #46 to disable system permanently (steering still locks mechanically with key out). 1-2 hours to diagnose and defeat, or 2-3 hours to replace actuator.
Estimated cost: $150-800
Transmission Mounts Collapsing
Common · low severity
Typical onset: 60,000-100,000 mi
Symptoms: Clunking on hard acceleration or deceleration, Excessive driveline movement felt through shifter, Vibration at idle in gear
Fix: Factory mounts wear quickly, especially with spirited driving. Replace all drivetrain mounts as a set. 3-4 hours labor. Polyurethane aftermarket mounts last longer but increase NVH.
Estimated cost: $500-900
Owner tips
Check oil every 500 miles religiously—early VQ37 engines eat oil even when 'healthy'
Manual trans: budget for CSC replacement preventively if buying high-mileage, or upgrade immediately
Pull fuse #46 (steering lock) as preventive measure—it WILL fail eventually
Use Ester oil (Nissan spec) and change every 3,750 miles to slow ring carbon buildup
Avoid track use without oil cooler, transmission cooler, and diff cooler upgrades
Buy one if you love the platform and budget $3K-5K reserve for the CSC and potential engine work—fantastic driver's car but the oil consumption issue is a ticking time bomb.
