The 2020 370Z with the VQ37VHR engine is a proven sports car platform, but heat management issues and aggressive driving lead to predictable wear patterns. The manual transmission is bulletproof, but the 7-speed auto has cooling vulnerabilities.
Transmission Oil Cooler Failure (7-speed Auto Only)
Common · high severity
Typical onset: 40,000-80,000 mi
Symptoms: transmission overheating warnings, limp mode during spirited driving or hot weather, burnt ATF smell, erratic shifting when hot
Fix: Factory cooler is undersized for performance use. Replace with OEM or aftermarket upgraded unit, flush contaminated fluid. 3-4 hours labor including fluid service.
Symptoms: clutch pedal stays on floor, difficulty shifting into gear, clutch fluid leak visible at bellhousing, sudden loss of clutch engagement
Fix: Internal slave cylinder fails, requires transmission removal. Smart owners upgrade to external conversion kit during repair. 8-10 hours labor for OEM replacement, add 2 hours for conversion kit install.
Estimated cost: $1,200-2,000 OEM, $1,800-2,500 with conversion kit
Fuel Starve Under High-G Cornering
Occasional · medium severity
Symptoms: engine hesitation or cutting out in sustained right-hand turns, problem worse below half tank, stumble during track days or aggressive canyon driving
Fix: Factory fuel pump design allows fuel to slosh away from pickup. Aftermarket surge tank or return-style fuel system required for track use. Some owners add simple baffles. 4-6 hours labor for proper fix.
Estimated cost: $600-1,500 depending on solution
Transmission Mount Deterioration
Common · low severity
Typical onset: 50,000-90,000 mi
Symptoms: clunking when shifting or launching, excessive driveline vibration, visible tearing or separation in rubber mount, shifter feel becomes vague
Fix: Hydraulic transmission mount fails from spirited driving. Simple swap, accessible from underneath. 1.5-2 hours labor. Upgrade to stiffer polyurethane available.
Symptoms: consuming 1+ quart per 1,000 miles, blue smoke on startup or deceleration, oil residue around valve covers, low oil warnings between changes
Fix: Oil gallery gaskets deteriorate, causing excessive consumption. Requires engine disassembly to upper block level. Sometimes warrants used engine swap instead. 18-25 hours labor for in-chassis repair.
Estimated cost: $3,500-6,000 gasket replacement, $4,500-7,500 used engine swap
Steering Lock Module Failure
Occasional · high severity
Symptoms: push-button start works but steering won't unlock, error message on dash, stranded in parking lot, clicking noise from steering column on start attempt
Fix: Electronic steering lock motor fails, preventing vehicle from starting. Common across Nissan lineup. Dealer-only programming required. 2 hours labor plus module. Many owners proactively delete/bypass.
Estimated cost: $600-1,000 OEM replacement, $200-400 for aftermarket delete kit
Owner tips
Change diff fluid every 30k miles if driven hard—factory fill breaks down quickly
Install transmission and diff coolers if tracking or in hot climates, especially with the 7-speed auto
If buying manual, budget immediately for CSC conversion kit—it's not 'if' but 'when'
Keep fuel above half-tank for spirited driving to avoid fuel starve issues
Check oil level religiously; consumption issues can sneak up on VQ37 engines past 60k miles
Buy the manual if you can live with the CSC issue, avoid the auto unless it has cooler upgrades—otherwise a solid, reliable sports car platform with known weak points that are manageable.
