The 2017 Quattroporte with the 4.2L V8 (Ferrari-derived engine) is a handbuilt Italian luxury sedan with impressive performance but notorious for catastrophic engine failures and expensive drivetrain issues that can total the car's value.
Catastrophic Engine Failure - Piston Ring / Bore Scoring
Common · high severityTypical onset: 40,000-80,000 mi
Symptoms: Excessive oil consumption (1+ quart per 1,000 miles), Blue smoke on startup or acceleration, Loss of compression and power, Metallic knocking sounds from cylinder bank, Check engine light with misfire codes
Fix: The 4.2L suffers from known piston ring land failure and cylinder bore scoring. Requires complete engine rebuild or short block replacement. Expect 40-60 labor hours for proper rebuild with machine work, new pistons, rings, bearings, gaskets. Many shops recommend replacing rather than rebuilding due to core damage.
Estimated cost: $18,000-35,000
ZF 8-Speed Transmission Oil Cooler Failure
Common · high severityTypical onset: 50,000-90,000 mi
Symptoms: Transmission fluid mixing with coolant (strawberry milkshake in reservoir), Harsh shifts or slipping, Transmission overheating warnings, Complete transmission failure if contamination not caught early
Fix: Internal cooler in the radiator fails, allowing cross-contamination. Requires transmission oil cooler replacement, complete fluid flush of both cooling and transmission systems. If caught late, transmission rebuild needed (add $8,000-12,000). 8-12 hours for cooler and flush alone.
Estimated cost: $2,500-4,500
Rear Differential Failure
Occasional · high severityTypical onset: 60,000-100,000 mi
Symptoms: Whining or howling noise from rear, speed-dependent, Clunking when engaging drive or reverse, Vibration under acceleration, Metal shavings in differential fluid
Fix: Limited-slip differential bearings and gears fail prematurely, especially in high-performance driving. Requires differential rebuild or replacement unit. Genuine Maserati parts only. 10-14 hours labor for removal, rebuild, and reinstallation.
Estimated cost: $4,500-7,500
Transmission Shift Solenoid Pack Failure
Common · medium severityTypical onset: 55,000-95,000 mi
Symptoms: Harsh or delayed shifts, Stuck in gear or limp mode, Transmission fault warnings on dash, Erratic shifting patterns
Fix: ZF mechatronic unit solenoids fail, common across this platform. Requires dropping transmission pan, replacing entire solenoid pack and valve body adaptation. 6-8 hours labor plus genuine ZF parts.
Estimated cost: $2,800-4,200
High-Pressure Fuel Pump Failure
Occasional · medium severityTypical onset: 70,000-110,000 mi
Symptoms: Hard starting, especially when hot, Rough idle and hesitation, Loss of power under load, Fuel system pressure codes, No-start condition
Fix: Direct injection system uses high-pressure pump that fails from contamination or wear. Located on engine, requires fuel system depressurization and special tools. 4-6 hours labor, expensive OEM part required.
Estimated cost: $2,200-3,500
Engine and Transmission Mount Failure
Common · low severityTypical onset: 45,000-75,000 mi
Symptoms: Excessive vibration at idle, Clunking when shifting or accelerating, Visible engine movement in bay, Transmission thunk when engaging drive
Fix: Hydraulic mounts deteriorate quickly, especially transmission mount. Requires lift and support of drivetrain. Multiple mounts typically need replacement simultaneously. 3-5 hours for all mounts.
Estimated cost: $1,200-2,000
Absolute no unless you have deep pockets or access to cheap Ferrari-trained labor — engine failure is more likely than not before 100,000 miles and will exceed the car's value.
