2015 MASERATI GRANTURISMO

Typical onset: 40,000-80,000 mi

Symptoms: Transmission slipping or harsh shifts, Check engine light with trans temp codes, Pink fluid under car (coolant mixing with ATF), Milky or strawberry-colored transmission fluid

Fix: Replace transmission oil cooler and flush both coolant and transmission systems completely. Contaminated fluid destroys clutch packs quickly. 6-8 hours labor including proper fluid flushing procedures. If caught late, transmission rebuild adds $8K-12K.

Estimated cost: $1,800-3,200

Typical onset: 50,000-90,000 mi

Symptoms: Clunking when shifting from Park to Drive, Vibration through cabin at idle, Excessive driveline movement during acceleration, Visible sagging or cracks in rubber mounts

Fix: Replace transmission mounts—these cars are heavy and the ZF transmission uses hydraulic mounts that fail predictably. Front mount is worst. 3-4 hours labor, requires subframe support.

Estimated cost: $900-1,600

Typical onset: 60,000-100,000 mi

Symptoms: Burning 1+ quart per 1,000 miles, Blue smoke on cold start or deceleration, Carbon buildup on spark plugs, Loss of power and rough idle as it progresses

Fix: Piston ring wear is a known F136 issue—caused by bore glazing and inadequate oil scraping. Repair requires engine-out service, cylinder honing/boring, new pistons and rings. 40-60 hours labor for proper rebuild. Some shops do top-end only (heads-off) but it often comes back. If cylinders are scored, short block replacement needed.

Estimated cost: $12,000-22,000

Typical onset: 70,000-110,000 mi

Symptoms: Rough idle or stumbling at low RPM, Check engine light with camshaft position codes (P0010, P0011), Rattling noise from valve covers on cold start, Reduced power and poor fuel economy

Fix: VVT solenoids and actuators fail from sludge buildup—this engine demands religious oil changes every 5K miles with proper 5W-40 synthetic. Requires valve cover removal, both banks. 5-7 hours labor. Replace all four actuators and solenoids as preventive.

Estimated cost: $2,200-3,800

Typical onset: 50,000-80,000 mi

Symptoms: Hesitation or stumble under acceleration, Difficulty starting when hot, Intermittent misfires across multiple cylinders, Fuel pump whining audible in cabin

Fix: In-tank fuel filter often neglected—Maserati service schedule calls for replacement every 30K miles but many owners skip it. Clogged filter starves injectors and kills the $1,200 pump. Requires fuel tank drop, 4-5 hours labor. Replace pump strainer, filter, and inspect pump while you're in there.

Estimated cost: $800-1,400

Typical onset: 80,000-120,000 mi

Symptoms: External coolant weeping at head-to-block junction, Slight coolant smell after hard driving, Minor coolant loss with no visible leaks underneath, No overheating or mixing into oil typically

Fix: F136 head gaskets develop external seepage—not catastrophic internal failure usually, but annoying and progressive. Requires heads-off service both banks, resurface heads, new gaskets and all valve cover seals. 24-30 hours labor. Good time to do valve stem seals and timing chain tensioners if high mileage.

Estimated cost: $6,500-9,500

Typical onset: 60,000-100,000 mi

Symptoms: Delayed or harsh 2-3 or 3-4 upshifts, Transmission stuck in one gear (limp mode), Check engine light with P0750-P0760 codes, Intermittent shifting issues when transmission is hot

Fix: ZF solenoid pack lives inside valve body—common failure point especially if transmission fluid service was neglected. Requires pan drop, valve body removal, solenoid replacement, new filter and fluid. 6-8 hours labor. Use only ZF LifeGuard 6 fluid, not generic Dexron.

Estimated cost: $1,600-2,800
