Top issues to watch for
The most serious Fiat Cinquecento problems ranked by severity. We track 5 known issues — here are the ones you need to know about first.
Dangerous
Structural corrosion to load-bearing areas (176)
The Cinquecento suffers from severe structural corrosion affecting load-bearing areas within 30cm of suspension mounting points and the vehicle structure itself. This occurs at unusually low mileages due to inadequate factory rustproofing and thin steel construction. MOT data shows failure rates 45 times higher than the fleet average for structural integrity failures, with the rigidity of the assembly becoming seriously compromised. This represents the most significant safety risk on surviving examples.
What happens if ignoredStructural failure can occur without warning, potentially causing loss of control or suspension collapse. The vehicle becomes immediately dangerous to drive and will fail its MOT. Repair typically requires extensive welding work that often exceeds the car's value, making most affected vehicles uneconomical to repair.

Major
Exhaust system failure (176)
The exhaust system fails at 28 times the national average rate, typically due to corrosion of the mild steel system and failure of mounting points. The rear silencer and centre section are particularly prone to perforation and detachment. This occurs at relatively low mileages due to the thin gauge steel used and inadequate corrosion protection from the factory.
What happens if ignoredA failing exhaust system will cause MOT failure and can allow dangerous fumes to enter the cabin. Detached sections can drag on the road surface creating a fire risk. Complete exhaust replacement is often required rather than partial repairs due to the extent of corrosion.

Major
Brake system corrosion and binding (176)
The brake system suffers from excessive corrosion affecting brake pipes, hoses, and calipers. MOT data shows brake hose ferrule corrosion at 9.4 times the fleet average and brake binding at 6.7 times the average. The brake pipes corrode at 4.1 times the fleet rate. This is attributed to poor quality steel brake components and inadequate corrosion protection, compounded by the car's low ground clearance exposing brake components to road salt and water.
What happens if ignoredBrake system failure can result in complete loss of braking ability or brakes that bind and cause loss of control. Corroded brake components will cause MOT failure. Seized brake calipers can cause brake discs to overheat and warp. The entire brake system may require renewal on higher mileage examples.

Major
Head gasket failure (176)
The FIRE engines are prone to head gasket failure, particularly on the 899cc variant. This occurs due to the aluminium head expanding at a different rate to the cast iron block, causing the gasket to fail between cylinders or into the cooling system. The small cooling system capacity and basic thermostat design contribute to overheating episodes that accelerate gasket failure.
What happens if ignoredHead gasket failure leads to coolant loss, overheating, and potential engine seizure. Coolant entering the cylinders can cause hydrostatic lock and bent connecting rods. Repair requires engine removal and full head reconditioning, often costing more than the car's value on these models.
