Top issues to watch for

The most serious Maserati Quattroporte problems ranked by severity. We track 5 known issues — here are the ones you need to know about first.

Major
Shock absorber bush failure (IV)
IV2004–201240k–100k miles
The shock absorber mounting bushes on the 4.2L V8 Quattroporte fail at exceptionally high rates, with MOT data showing failure at 10.7 times the national fleet average. The rubber bushes deteriorate due to the car's weight and performance suspension setup, causing knocking noises over bumps and reduced handling precision. This is a well-documented weakness across the generation, with replacements typically lasting 30,000-40,000 miles before requiring renewal.
What happens if ignoredFailed shock absorber bushes reduce handling precision and allow excessive movement of the suspension assembly. While not immediately dangerous, the knocking noise is intrusive and the handling deterioration becomes pronounced. Replacement typically requires removal of the complete shock absorber assembly.

Major
Parking brake efficiency failure (IV)
IV2004–201260k–100k miles
The electronic parking brake system on 4.2L V8 models fails MOT testing at 4.9 times the national average, typically due to seized brake caliper mechanisms or worn brake pads specific to the rear axle. The system uses electric actuators to engage the rear brake calipers, and these actuators can seize or lose effectiveness over time, particularly when the car is not used regularly.
What happens if ignoredA parking brake that fails to meet minimum efficiency requirements will result in MOT failure and the car cannot be legally driven on the road. In severe cases where actuators have seized, the rear brakes may bind continuously, causing overheating and further damage to brake components.

Major
Suspension component corrosion (IV)
IV2004–201240k–80k miles
Suspension components on the 4.2L V8 models suffer from corrosion at 3.8 times the national fleet average, typically affecting control arms, subframe mounting points, and anti-roll bar components. The aluminium and steel components in the suspension system are vulnerable to galvanic corrosion, particularly where dissimilar metals meet, and road salt accelerates the process on UK cars.
What happens if ignoredSeverely corroded suspension components can fail suddenly, causing loss of control. Even moderate corrosion weakens the structural integrity of the suspension system and affects handling precision. Corroded components typically require complete replacement rather than repair.

Major
Spring failure (IV)
IV2004–201240k–100k miles
Coil springs on the 4.2L V8 Quattroporte fracture at 2.8 times the national fleet average, with the trend worsening according to recent MOT data. The springs are stressed by the car's 1,930kg kerb weight and performance suspension tuning. Spring failure typically occurs near the end coils and can happen without warning, causing sudden ride height loss and potential tyre damage.
What happens if ignoredA broken coil spring can cause sudden loss of ride height, potentially allowing the tyre to contact the wheel arch under compression. This creates a dangerous handling situation and can cause rapid tyre failure. The sharp end of a broken spring can also puncture the tyre.
