The 2018 370Z's VQ37VHR is generally robust, but this platform suffers from specific high-mileage engine failures, chronic transmission cooler failures, and some notorious fuel system quirks that can leave you stranded.
Symptoms: Pink or milky transmission fluid indicating coolant contamination, Transmission slipping or erratic shifting, Overheating transmission temp gauge readings, Catastrophic transmission failure if contamination progresses
Fix: Replace transmission oil cooler, flush entire cooling system and transmission multiple times to remove cross-contaminated fluids. If caught late, transmission rebuild required. 4-6 hours labor for cooler only, 15-20 hours if transmission damaged.
Symptoms: Engine stumbles or cuts out during aggressive cornering with less than half tank, Hesitation or bogging during track use or spirited mountain driving, Check engine light with lean fuel codes (P0171/P0174)
Fix: Design flaw where fuel sloshes away from pickup on low fuel. Aftermarket fuel starvation kit installation includes secondary baffles and pickup relocation. 3-4 hours labor dropping tank and modifying internals.
Symptoms: Clutch pedal stuck to floor or extremely soft engagement, Inability to shift gears or get into gear, Fluid leaking inside bell housing, Clutch engagement point changes dramatically
Fix: Internal slave cylinder requires transmission removal. Common practice is to replace clutch assembly simultaneously since transmission is already out. 8-10 hours labor.
VQ37VHR Oil Consumption and Gallery Gasket Failure
Occasional · high severity
Typical onset: 80,000-130,000 mi
Symptoms: Excessive oil consumption (quart every 1,000-2,000 miles), Valve train noise or ticking that doesn't resolve with fresh oil, Low oil pressure at idle when hot, Metallic debris in oil filter during changes
Fix: Oil gallery gaskets deteriorate causing pressure loss; piston ring wear from inadequate lubrication. Requires engine removal, teardown, gallery gasket replacement, honing cylinders, new rings minimum. Some cases need oversized pistons. 25-35 hours labor for proper rebuild.
Estimated cost: $4,500-7,500
Steering Lock Mechanism Failure
Occasional · high severity
Typical onset: 50,000-90,000 mi
Symptoms: Car won't start with steering lock error on dash, Clicking noise from steering column when starting, Intermittent no-start condition that resolves after waiting, Complete inability to start requiring tow
Fix: Electronic steering lock actuator fails and prevents starting entirely. Common preventive measure is to remove fuse to disable system. Replacement requires column disassembly. 2-3 hours labor.
Estimated cost: $400-700 (many owners just pull the fuse)
Transmission Mount Failure
Common · low severity
Typical onset: 60,000-100,000 mi
Symptoms: Clunking when shifting gears or engaging clutch, Excessive vibration at idle in gear, Shifter slop or difficulty finding gears, Visible cracking or separation of rubber mount
Fix: Transmission mount deteriorates from engine torque and heat. Straightforward replacement but requires supporting transmission. 1.5-2 hours labor.
Estimated cost: $250-450
Concentric Slave Cylinder (CSC) Bearing Failure
Occasional · medium severity
Typical onset: 40,000-80,000 mi
Symptoms: Grinding or rattling noise when clutch pedal depressed, Clutch chatter during engagement, Difficulty shifting into first or reverse, Bearing noise that changes with clutch pedal position
Fix: The CSC bearing wears prematurely, especially with performance driving. Requires transmission removal same as slave cylinder. Smart shops do clutch, slave, and bearing together. 8-10 hours labor.
Estimated cost: $1,500-2,500 (combined with clutch job)
Owner tips
Keep fuel tank above half on spirited drives to avoid starvation issues
Check transmission fluid color religiously on automatics every 5,000 miles for coolant contamination
Monitor oil consumption closely after 60,000 miles and address gallery gaskets before rings wear
Pull the steering lock fuse (common preventive mod in the community) to avoid being stranded
Manual transmission buyers: budget for clutch/slave/bearing as a package deal around 60k miles
Use quality synthetic oil and change every 5,000 miles maximum—this engine is sensitive to oil quality
Buy one if you love the driving experience and accept that the 7AT cooler and manual CSC are virtually guaranteed expenses—budget $3-5k for deferred maintenance on anything over 50k miles.

Nissan North America, Inc. (Nissan) is recalling certain 2018 Nissan 370Z vehicles. The driver's side curtain air bag may have been installed incorrectly during production, possibly affecting its deployment. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 214, "Side Impact Protection," and 226, "Ejection Mitigation."
Consequence: The incorrect curtain air bag installation can prevent the air bag from deploying correctly in the event of a crash, increasing the risk of injury.
Remedy: Nissan will notify owners, and dealers will inspect the curtain air bag, correcting its installation as necessary, free of charge. The recall began May 1, 2018. Owners may contact Nissan customer service at 1-800-867-7669.
Size-standard part numbers — verify your connector type before buying. Rear blades are model-specific; check the package's vehicle list.
