2013 MASERATI GRANTURISMO

Typical onset: 40,000-80,000 mi

Symptoms: Cold-start rattle for first 10-30 seconds, Metallic knocking from engine bay, Oil consumption 1+ quart per 1,000 miles, White smoke on startup, Check engine light with misfire codes

Fix: Requires complete engine-out tear-down. Damaged cylinders need re-sleeving or block replacement, plus new pistons, rings, bearings. Expect 60-80 hours labor for full rebuild or 40-50 hours for short block swap. This is the death sentence failure—aftermarket sleeves run $8k-12k, Maserati short block $18k-25k.

Estimated cost: $15,000-35,000

Typical onset: 60,000-100,000 mi

Symptoms: Harsh 2-3 or 3-4 shifts, Limp mode activation, Delayed engagement into gear, Check engine light with transmission codes P0750-P0760 range, Erratic shifting when transmission is hot

Fix: ZF 6HP26 solenoid pack lives in the valve body. Transmission must be dropped (8-12 hours), pan removed, valve body extracted. Replace entire solenoid set plus conductor plate—never do one solenoid. OEM Maserati parts only; aftermarket fails quickly.

Estimated cost: $2,800-4,500

Typical onset: 70,000-120,000 mi

Symptoms: Transmission fluid pooling under car center-front, Low transmission fluid warning, Burnt transmission fluid smell, Pink/red fluid on driveway, Slipping or delayed shifts due to low fluid

Fix: Hard lines from transmission to front-mounted cooler corrode at fittings or develop pinhole leaks. Requires lift access, sometimes subframe lowering for complete line replacement. 4-7 hours labor depending on which line fails. Replace both lines while you're in there.

Estimated cost: $1,200-2,200

Typical onset: 50,000-90,000 mi

Symptoms: Clunk when shifting from Park to Drive, Vibration at idle in gear, Excessive drivetrain movement over bumps, Thud when accelerating from stop

Fix: Hydraulic transmission mount fails—common on ZF transmissions in all platforms. Requires transmission support and mount replacement from underneath. 2-3 hours labor. Use OEM Maserati or Lemforder—aftermarket lasts 20k miles.

Estimated cost: $600-1,000

Typical onset: 60,000-100,000 mi

Symptoms: Rough idle and hesitation under acceleration, Intermittent no-start conditions, Loss of power at highway speeds, Fuel pump whine audible from rear, Check engine light with fuel trim or lean codes

Fix: Maserati fuel filter service interval is criminally long (48k miles). Clogged filter starves pump, killing it prematurely. Filter lives under car mid-chassis—2 hours labor. In-tank pump replacement requires tank drop—add 6-8 hours. Always replace filter when doing pump.

Estimated cost: $400-800 filter only, $1,800-3,000 with pump

Typical onset: 70,000-110,000 mi

Symptoms: Rough cold idle that smooths when warm, Check engine light with camshaft position codes, Ticking from valve covers, Reduced power and throttle response, Poor fuel economy

Fix: Variable valve timing solenoids stick due to oil sludge or fail electrically. Bank-specific codes point to which side. Solenoids accessible under cam covers—4-6 hours per bank including gaskets. If timing chain jumped due to worn guides/tensioners, that's 25-35 hours with engine-out. Inspect timing components with scope before assuming solenoids.

Estimated cost: $1,200-2,500 solenoids, $8,000-15,000 timing chain job
