The 812 Superfast's 6.5L naturally-aspirated V12 is a masterpiece when healthy, but early examples have shown catastrophic engine failures tied to assembly quality and lubrication issues—particularly piston ring wear and bearing failures that can grenade the motor. Transmission oil cooler leaks and shift solenoid glitches also plague the dual-clutch gearbox.
Catastrophic Engine Failure — Piston Ring & Bearing Wear
Occasional · high severityTypical onset: 15,000-35,000 mi
Symptoms: Excessive oil consumption (1+ quart per 1,000 mi), Blue smoke on startup or hard acceleration, Metallic knocking or ticking from lower end, Sudden loss of oil pressure — engine seizure
Fix: Full engine-out rebuild or short-block replacement required. Reports trace failures to insufficient ring seating during break-in or defective rings allowing fuel wash into bores. Expect 60-80 hours labor plus Ferrari OEM parts (pistons, rings, bearings, gaskets). Some dealers have covered under goodwill; independents cite poor factory QC on 2017-2018 builds.
Estimated cost: $45,000-75,000
Transmission Oil Cooler Line Leak
Common · medium severityTypical onset: 20,000-50,000 mi
Symptoms: Transmission fluid spots under car (red/brown fluid), Burnt smell after spirited driving, Transmission overheat warning on dash, Slipping or delayed shifts when hot
Fix: Rubber-lined hard lines crack at crimp joints; Ferrari revised part number mid-2018. Replace both feed and return lines, flush cooler, refill with Tutela transmission fluid. 8-12 hours labor with undertray removal and fluid service.
Estimated cost: $3,500-5,200
Shift Solenoid Pack Failure (DCT)
Occasional · medium severityTypical onset: 30,000-60,000 mi
Symptoms: Hard or lurching shifts, especially 2-3 and 5-6, Gear selection fault messages, Transmission enters limp mode (stuck in one gear), Metallic clunk when engaging Drive from Park
Fix: DCT mechatronic unit solenoids wear or suffer from contamination due to cooler leaks (see above). Replace solenoid pack and perform clutch adaptation. If caught early, no clutch damage; if ignored, dual-clutch replacement adds $15k+. 10-14 hours with fluid service.
Estimated cost: $4,800-7,500
Transmission Mount Deterioration
Common · low severityTypical onset: 25,000-50,000 mi
Symptoms: Clunking or banging on takeoff or shifts, Vibration through cabin at idle in gear, Excessive driveline movement visible during throttle blips
Fix: Rear transaxle mount uses a fluid-filled bushing that fails under high torque loads. Replace mount and alignment bushings. 4-6 hours labor; requires lifting rear subframe slightly.
Estimated cost: $1,800-2,800
Fuel Filter Clogging (Ethanol Sensitivity)
Occasional · medium severitySymptoms: Rough idle or stumbling under hard acceleration, Check engine light with lean fuel codes (P0171/P0174), Loss of top-end power above 6,000 RPM, Hard starting after sitting overnight
Fix: In-tank filter degrades rapidly with E10+ fuel; Ferrari specifies low-ethanol premium. Replace filter and both fuel pumps if contaminated. Tank drop required. 6-8 hours labor.
Estimated cost: $2,200-3,500
Head Gasket Weeping (Cylinder 2 & 11)
Rare · high severityTypical onset: 40,000-70,000 mi
Symptoms: Coolant smell in cabin or from engine bay, Slow coolant loss without visible external leaks, White residue around head-to-block seam, Overheating under sustained high RPM
Fix: Gaskets fail at rear-bank outer cylinders due to localized overheating from marginal coolant flow. Both heads off, resurface, new gaskets, timing chain inspection. Engine-out not required but recommended for thoroughness. 40-50 hours labor.
Estimated cost: $18,000-28,000
Buy only with full service records and post-warranty engine inspection—the V12 is glorious but 2017s are landmines; 2019+ models have better assembly quality.
