Pininfarina-styled Italian executive saloon with a Ferrari-derived 4.2-litre V8 that sounds magnificent. It was a genuine four-door supercar when new, and depreciation has made it accessible, but running costs remain firmly in the luxury bracket. Specialist knowledge is essential for maintenance, and the car rewards regular use far more than sitting idle.· more· less
Expensive and complex to maintainSteering rack leaks are endemic
Buy if: You want an exotic Italian saloon with a Ferrari V8, accept high running costs, and can find a well-maintained ZF automatic example with full specialist service history.
Avoid if: You cannot budget for four-figure repair bills, want a trouble-free daily driver, or are looking at a DuoSelect model for city driving.
Steering rack develops leaks on virtually all examples, sometimes with as little as 15,000 km on the clock · more· less
This is the most widespread issue on the Quattroporte V. In inspections of multiple cars, nearly all showed signs of steering rack leakage regardless of mileage. The power steering pump also fails frequently. Minor seepage can be managed temporarily with seal-swelling additives in the power steering fluid, but eventually the rack and often the pump need replacement. A new rack from Maserati is extremely expensive, and combined rack and pump replacement typically exceeds €4,000-5,500 at a dealer. Independent specialists can source reconditioned racks for less, bringing total cost to around €1,500-3,000. The leak worsens gradually, so catching it early during a pre-purchase inspection is critical.
Camshaft variator (VVT) rattle and failure
€1,500 - 4,0002 of 8
VVT system fails to return to base position, causing a distinctive rattle on cold start and overrun · more· less
The variable valve timing system uses hydraulic variators that can fail, preventing the locking pin from engaging when the engine is shut off. This causes a characteristic rattle on cold start lasting several seconds, and sometimes on overrun. The 4.2-litre dry-sump engines (DuoSelect cars) have a relatively low failure rate of approximately 1 in 20. The 4.2-litre wet-sump engines (ZF automatic) are slightly more susceptible. The 4.7-litre engines have the highest failure rate (roughly 1 in 3) but are not covered in this report. Engines built after September 2010 received upgraded variators from the factory. Repair costs approximately €1,500-2,000 per side at a specialist, with parts around €650 per variator. If both sides need doing, expect €3,000-4,000 total. Always listen carefully on a cold start during any test drive.
DuoSelect clutch wear
€2,000 - 3,5003 of 8
Automated manual clutch wears rapidly in stop-start traffic, lasting as little as 30,000 km · more· less
The DuoSelect (F1-style) transmission is an automated manual with a dry twin-plate clutch. Maserati's records place the DuoSelect era from 2003 to 2008, and its technical portal lists both DuoSelect and automatic cars for 2007, so the two overlap rather than splitting neatly at a model year. If driven gently or in heavy traffic, the clutch wears very quickly, sometimes lasting as little as 30,000 km. Highway-biased driving can extend life to 60,000-80,000 km. Clutch replacement costs approximately €2,000-3,500 including parts and labor. The hydraulic gear selectors can also develop faults causing slow or slurred shifts, with each selector costing €2,000-2,500 to replace. This issue only affects DuoSelect cars. The ZF 6-speed automatic, offered alongside DuoSelect from 2007, is significantly more reliable and is the strongly recommended transmission choice for used buyers.
Skyhook adaptive suspension damper failure
€2,000 - 5,0004 of 8
Skyhook dampers leak or the ECU overheats, causing suspension warning lights · more· less
The optional Skyhook suspension uses hydraulic ZF CDC dampers with electromechanical control valves that adjust firmness in real time; it is not a magnetorheological system. These dampers develop leaks over time, typically after 60,000-100,000 km. Each OEM damper costs approximately €1,000-1,500, and the suspension ECU can also fail (roughly €1,000 for the unit alone). In warm weather, the Skyhook ECU is prone to overheating and throwing errors. Replacing all four dampers at a Maserati dealer can reach €5,000+. Some owners convert to conventional sport dampers as a more affordable and reliable long-term solution. Not all Quattroporte V models have Skyhook; check if the car is equipped before purchase.
Electrical system faults and battery drain
€500 - 3,0005 of 8
Complex electrical system causes parasitic drain, warning light storms, and intermittent module failures · more· less
The Quattroporte V is described by automotive journalists as being immensely and scarily complex electrically. Problems include sporadic warning lights appearing across the dashboard, unresponsive infotainment, power window and mirror failures, and parasitic battery drain that can flatten the battery within 2-7 days if the car is not driven regularly. A high-quality trickle charger is essential for any Quattroporte V owner, and the battery itself should be a strong one: the relevant figure is cold cranking amps (800 A or more), while capacity is the separate Ah rating. Diagnosis typically requires Maserati SD3 diagnostic equipment, which limits where the car can be serviced. Individual module replacements range from €300-1,500 depending on the component. Budget €2,000-3,000 annually for unexpected electrical diagnostics and repairs on high-mileage examples.
Window regulator failure
€400 - 8006 of 8
Regulators fail frequently, causing windows to drop or stop operating · more· less
Window regulators are a well-known weak point on the Quattroporte V. The mechanism fails, causing the window to drop suddenly or stop operating entirely. Replacement at a Maserati dealer costs approximately €600-800 per window including parts and labor. Aftermarket regulators are available for less (around €200-300 for the part), reducing total cost to approximately €400-500 at an independent specialist. Most owners report needing at least one regulator replaced during ownership, and some report all four eventually failing. Test all four windows during any pre-purchase inspection.
Valve cover gasket oil leaks
€500 - 1,5007 of 8
Gaskets seep oil onto exhaust manifolds, causing smoke and burning oil smell · more· less
The 4.2-litre V8's valve cover gaskets gradually deteriorate and begin seeping oil, which drips onto the hot exhaust manifolds below. This produces a noticeable burning oil smell when idling and visible smoke on cold starts. While not dangerous in the short term, prolonged leaking can damage other components and creates a fire risk. The gaskets themselves cost approximately €150-250 for both sides. Labor takes approximately 4-6 hours at a specialist. Total repair cost at an independent shop is typically €500-800, while Maserati dealers can charge €1,200-1,500. This is a very common issue on high-mileage 4.2 engines and should be considered almost inevitable beyond 80,000-100,000 km.
Front suspension ball joint and tie rod wear
€1,000 - 3,0008 of 8
Ball joints on front A-arms wear prematurely, causing clunking over bumps · more· less
The front suspension design places heavy loads on the lower ball joints, which are mounted inverted compared to most cars. This causes accelerated wear, resulting in clunking noises when driving over bumps or uneven surfaces. The tie rod ends are also described as a notorious problem area. Repair is expensive because Maserati does not sell the ball joint separately; the complete control arm assembly must be replaced. Parts alone can cost €800-1,500 for a full front suspension refresh. At an independent specialist, total cost is typically €1,000-2,000. A dealer quote can reach €3,000 or more. Worn ball joints should be addressed promptly as they affect steering precision and safety.
High-maintenance exotic requiring specialist care and a healthy budget
The Quattroporte V with the 4.2-litre V8 is fundamentally a Ferrari-engined luxury saloon, and running costs reflect this. The steering rack leak issue is near-universal, electrical complexity demands specialist diagnostic equipment, and even routine parts are expensive. The ZF automatic is far more reliable than the DuoSelect, and the 4.2 dry-sump engine has lower variator failure rates than the later 4.7. With the right specialist, a documented service history, and realistic expectations about costs, the Quattroporte V can be a rewarding ownership experience. However, buyers expecting German-car reliability will be disappointed.
Full specialist service history
Complete Maserati dealer or approved specialist records are essential. Gaps in history on this car are a serious red flag.
Cold start test
Must start the engine completely cold. Listen carefully for variator rattle in the first 10-30 seconds.
Extended test drive
Drive for at least 30 minutes including urban and highway driving to allow all systems to reach operating temperature.
Battery condition
Check battery age and condition. Should be a strong unit, 800 A cold cranking or more. Weak battery causes cascading electrical faults.
Specific for this vehicle
Inspect steering rack for leaks
Look under the car at the steering rack area for any signs of power steering fluid. Check the fluid reservoir level. Even minor weeping needs attention: additives can hold it for a while, but it worsens gradually toward rack replacement.
Check all four power windows
Operate each window fully up and down multiple times. Listen for grinding or hesitation. Failed regulators are very common.
Verify transmission type (DuoSelect vs ZF)
If DuoSelect, check clutch wear indicator using diagnostic tool. If ZF automatic, test electronic handbrake operation.
+ 5 more checksShow less
Test Skyhook suspension (if equipped)
Check for any suspension warning lights. Visually inspect dampers for oil leakage. Switch between comfort and sport modes during test drive.
Check for oil leaks around valve covers
With engine warm, look and smell for burning oil around the top of the engine. Seeping valve cover gaskets are visible as wet/oily patches.
Verify rear tie rod recall completed
The rear tie rod recall over insufficient anti-corrosion material is dated 2005-2008 in US-market records, while the European campaign dates vary by country. Confirm by VIN with a Maserati dealer.
Check electrical systems comprehensively
Test every button, switch, seat motor, mirror, navigation screen, and sensor. Electrical faults are the most common complaint on these cars.
Inspect front suspension for play
Rock each front wheel at 12 and 6 o'clock with the car raised. Any significant play indicates worn ball joints requiring expensive control arm replacement.
