Top issues to watch for
The most serious Maserati Granturismo problems ranked by severity. We track 5 known issues — here are the ones you need to know about first.
Dangerous
Suspension component corrosion and damage (M145)
The GranTurismo's front suspension components, particularly control arms and subframe mounting points, suffer from accelerated corrosion that can lead to structural failure. MOT data shows this model fails at 86.5 times the national fleet average for suspension component damage or corrosion, primarily affecting 4.2L models from 40-60k miles. The aluminium suspension components develop galvanic corrosion where they meet steel mounting points, and the protective coatings deteriorate faster than expected. This is not routine maintenance but a design-related failure that can compromise vehicle safety.
What happens if ignoredIf suspension components fail due to corrosion, the car becomes unsafe to drive with potential for loss of control. Component replacement requires specialist knowledge and genuine Maserati parts. Repair costs typically range from £2,000-£5,000 depending on the extent of damage and number of components requiring replacement.

Major
Front spring failure (M145)
Coil spring failure affects both 4.2L and 4.7L GranTurismo models at 86.5 times the fleet average rate according to MOT data, with a worsening trend over recent years. The springs can fracture or seriously weaken, typically at the lower coils where road salt and debris accumulate. This appears to be related to the spring steel specification rather than overloading, as failures occur across all mileage bands from 20k miles onwards. A fractured spring can damage the tyre and affects vehicle stability.
What happens if ignoredA fractured spring reduces ride height and can damage the tyre. In severe cases, a broken spring end can puncture the tyre or interfere with steering. The car remains drivable with care but should be repaired promptly. Spring replacement requires specialist suspension tools and wheel alignment afterwards.

Minor
Shock absorber bush wear (M145)
The shock absorber mounting bushes deteriorate prematurely on the GranTurismo, with MOT data showing failure at 95.5 times the fleet average for the 4.2L engine. The rubber bushes that mount the shock absorbers to the chassis and suspension arms become soft and perished, leading to increased road noise and reduced handling precision. This affects the car's refined character and can accelerate wear in related suspension components if left unaddressed.
What happens if ignoredWorn shock absorber bushes reduce ride quality and handling precision. They allow excessive movement of the suspension components, which can accelerate wear in ball joints and other bushes. Replacement is straightforward but requires the suspension to be partially dismantled.

Minor
Suspension pin and joint wear (M145)
Ball joints, track rod ends, and anti-roll bar drop links wear at an accelerated rate on the GranTurismo, with MOT data showing failure at 86.5 times the fleet average. Both the 4.2L and 4.7L engines are affected, typically from 40k miles onwards. The suspension geometry places higher loads on these components than typical road cars, and the original equipment parts appear undersized for the application. Worn joints create play in the suspension that affects both handling and tyre wear patterns.
What happens if ignoredWorn suspension joints create imprecise handling and can cause uneven tyre wear patterns. Multiple worn joints can make the car feel unstable at speed. Individual components can be replaced as they fail, but labour costs are high due to the complexity of accessing components on this platform.
