What goes wrong, what it costs, and what to check before you buy a used Fiat Cinquecento.
The Fiat Cinquecento occupies a niche position on the UK market.
We track 5 known issues across the Fiat Cinquecento range, including 1 rated as safety-critical. Knowing which variants and configurations to approach with caution can save you from expensive surprises after purchase.

176 (1993–1998) — Engine options included the 0.9 FIRE, 1.1 FIRE. Our database flags 5 known issues on this generation, 1 of which are rated as safety-critical. The most significant concern is Structural corrosion to load-bearing areas (£800–£2,000 to address).
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.
Structural 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.
Inspect the wheel arches, sills, jacking points and door bottoms carefully. Press gently on sills to check for soft spots. Look underneath for corrosion on structural components. Check the MOT history for corrosion-related advisories or failures.
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.
A 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.
Check for any engine warning lights on the dashboard. Ask about the car's MOT emissions history — repeated failures suggest underlying issues. A pre-purchase diagnostic scan is especially worthwhile to check for stored emissions fault codes.
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.
Brake 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.
Check brake disc condition for lipping or scoring. Test braking at moderate speed for pulling to one side or vibration through the steering wheel. Review MOT advisories for brake-related items.
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.
Head 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.
Look for oil weeping around gasket surfaces — rocker cover, sump and timing cover are common areas. Check for coolant mixing with oil (creamy residue on the filler cap) which indicates a more serious head gasket issue.
The model shows excessive fluid leakage at The FIRE engines are known for oil leaks from the rocker cover gasket, crankshaft seals, and oil filter housing. These leaks develop due to aging rubber seals and gaskets, compounded by the engine's high operating temperatures in the small engine bay.
Oil leaks can contaminate the timing belt leading to premature failure. Significant leaks will cause MOT failure due to environmental hazard. Engine oil loss can lead to seizure if not regularly topped up. Leaked fluids can create fire risk on hot exhaust components.
Check the oil level before the engine is started. Ask the seller how often they top up the oil between services. After a test drive, check the level again and look behind the car for blue or grey exhaust smoke under acceleration.

Based on 2k real DVSA MOT tests, the Fiat Cinquecento fails more often than average on several items. The biggest outlier is service brake efficiency below minimum requirement at 119x the fleet average, followed by parking brake efficiency less than 50% of the r... (75x).
When viewing a specific car, check its MOT history for recurring advisories in these categories. See the full Fiat Cinquecento MOT failure breakdown for data at every mileage point.
Routine servicing (oil and filter change every 6k miles) typically costs £40–£70 at an independent garage.
The bigger-ticket items to budget for include timing belt (£200–£350).

The Fiat Cinquecento has some well-documented weak points, including 1 safety-critical issue that demand careful checking. The right example, properly maintained, can still be a sound purchase — but cutting corners on the pre-purchase inspection is not advisable.
