The 2017 GranTurismo uses Ferrari's 4.7L F136 V8 and ZF 6-speed auto. Beautiful and sonorous, but aging platform means expensive wear items and catastrophic engine failures lurk past 40k miles if maintenance lapses.
Catastrophic Engine Failure (Connecting Rod Bearing Failure)
Occasional · high severityTypical onset: 40,000-80,000 mi
Symptoms: Metallic knocking at idle that worsens with RPM, Oil pressure warning light, Metal shavings in oil during changes, Sudden loss of power and engine seizure in severe cases
Fix: Complete engine rebuild or replacement required. Rod bearings wear prematurely due to oiling system design and extended oil change intervals. Most common on engines that saw 10k+ mile oil changes. Expect 60-80 labor hours for proper rebuild including block honing, new pistons, rings, bearings, and gaskets. Many shops sub this out or recommend used/remanufactured long block.
Estimated cost: $18,000-35,000
ZF Transmission Valve Body and Solenoid Failure
Common · high severityTypical onset: 60,000-90,000 mi
Symptoms: Harsh or delayed shifts especially 2-3 and 3-4, Transmission slipping or refusing to engage gears, Check engine light with shift solenoid codes (P0750-P0770 range), Limp mode activation
Fix: ZF 6HP26 valve body wears and solenoids fail. Requires transmission removal, valve body replacement or rebuild, and all solenoids. 12-16 hours labor. Some attempt solenoid-only replacement but valve body wear usually returns within 20k miles. Proper fluid flush mandatory after repair.
Estimated cost: $4,500-7,500
Transmission Oil Cooler Line Leaks
Common · medium severityTypical onset: 50,000-100,000 mi
Symptoms: Transmission fluid puddles under engine bay center, Burnt transmission fluid smell, Low fluid level on dipstick, Overheating transmission with slipping under load
Fix: Hard lines and rubber sections crack from heat cycling. Lines run along engine valley and require significant disassembly to access properly. 6-8 hours labor. Replace all cooler lines as a set, not individually. OEM parts essential—aftermarket lines fail quickly.
Estimated cost: $1,800-2,800
Rear Transmission Mount Failure
Common · low severityTypical onset: 40,000-70,000 mi
Symptoms: Clunking when shifting from Park to Drive or Reverse, Vibration through center console at idle, Excessive drivetrain movement visible during acceleration, Banging noise over bumps from tunnel area
Fix: Rubber mount deteriorates from heat and age. Access is tight but straightforward once exhaust is dropped. 3-4 hours labor. Inspect front engine mounts simultaneously—they often fail around same interval.
Estimated cost: $800-1,200
Fuel Filter Clogging (High-Pressure)
Occasional · medium severityTypical onset: 60,000-80,000 mi
Symptoms: Hard starting especially when hot, Stumbling and hesitation under acceleration, Limp mode at highway speeds, Fuel pressure codes (P0087), Check engine light
Fix: High-pressure filter in fuel tank assembly clogs from sediment, especially if premium fuel discipline lapses. Requires fuel tank drop. 4-5 hours labor. Maserati officially says 'lifetime' filter but real-world is 60-80k. Replace both high-pressure and inline filters simultaneously.
Estimated cost: $900-1,400
Camshaft Variable Valve Timing Solenoid Failure
Occasional · medium severityTypical onset: 70,000-110,000 mi
Symptoms: Rough idle and poor low-end torque, Check engine light with P0010-P0014 codes (VVT system), Rattling from valve covers on cold start, Reduced fuel economy
Fix: VVT solenoids stick from sludge buildup. Eight solenoids total (one per cam). Access requires valve cover removal both sides. Often accompanied by cam position sensor failures. 6-8 hours labor to do all solenoids preventively. Clean oil journals during repair.
Estimated cost: $1,500-2,500
Buy only with comprehensive service records showing religious oil changes and recent transmission service; otherwise budget for engine replacement within first year—beautiful but financially brutal if neglected.
