Retro charm with the roof down, smiles guaranteed
The Fiat 500C is the convertible version of the hugely popular retro-styled Fiat 500, featuring a sliding fabric roof rather than a full fold-down soft top. It competes with the Mini Convertible but at a significantly lower price point, targeting fashion-conscious urban buyers who want open-air fun without sacrificing practicality. It's more of a lifestyle accessory than a performance car, thriving on charm and kerb appeal.
We track 5 known issues across the Fiat 500C range, including 1 rated as safety-critical. Knowing which variants and configurations to approach with caution can save you from expensive surprises after purchase.

312 (2007–2020) — Petrol options included the 0.9 TwinAir, 1.2 Fire, 1.4 Fire, with 1.3 MultiJet on the diesel side. Our database flags 5 known issues on this generation, 1 of which are rated as safety-critical. The most significant concern is Suspension component excessive damage or corrosion (£500–£1,500 to address).
MOT data shows the 500C fails structural suspension component tests at 635.3 times the national fleet average, with failures recorded across all mileage bands from 20,000 miles upward. This indicates premature corrosion or damage to load-bearing suspension components including control arms, subframes, and mounting points. The convertible body requires additional structural reinforcement compared to the standard 500, but the suspension mounting areas appear vulnerable to accelerated deterioration. This is classified as dangerous because compromised suspension mounting can affect vehicle stability and steering control.
Severely corroded or damaged suspension mounting points can lead to suspension component detachment, loss of steering control, or wheel detachment while driving. Depending on the extent of structural damage, repair may require welding work, subframe replacement, or in extreme cases may be uneconomical. Typical repair costs range from £500-2000 depending on which components are affected.
Listen for knocking, clunking or rattling over bumps during the test drive. Inspect the underside for corroded or cracked suspension components. Check the MOT history for suspension-related advisories, which often predict future failures.
MOT data shows shock absorber bushes failing at 635.3 times the national fleet average, with 1,165 recorded failures across all engine variants. The failures appear across the entire mileage range including cars under 20,000 miles, indicating a fundamental design or material quality issue with the suspension bushes. This affects ride quality, handling precision, and can accelerate wear on other suspension components including shock absorbers and springs. The problem appears universal across petrol and diesel variants.
Worn suspension bushes degrade ride quality, handling, and steering precision. They accelerate wear on shock absorbers, springs, and tyres due to poor suspension geometry. While not immediately dangerous, severely worn bushes can lead to MOT failure and poor vehicle stability. Replacement typically involves multiple bushes to restore proper suspension function.

MOT data shows spring or spring component failures at 635.3 times the national fleet average, with 1,165 recorded failures affecting all engine variants including cars under 20,000 miles. This indicates a systematic weakness in the coil spring design or material specification. Fractured springs affect vehicle ride height, handling, and can cause damage to tyres or bodywork if a spring end detaches. The high failure rate at low mileages suggests manufacturing defects rather than normal wear.
A fractured coil spring affects ride quality, vehicle stability, and tyre wear patterns. In severe cases, a completely detached spring end can damage the tyre sidewall, brake lines, or bodywork. The car should not be driven with a confirmed broken spring as handling becomes unpredictable. Spring replacement typically requires both sides to be changed to maintain even ride height and handling balance.

The two-cylinder TwinAir 0.9L engine uses advanced technology including MultiAir valve control and high turbocharger boost to extract significant power from a small displacement. Owner forums and specialist mechanics report higher than expected failure rates for timing components, oil system problems, and internal wear patterns compared to the conventional 1.2L Fire engine. The MultiAir system requires precise oil pressure control and is sensitive to oil quality and service intervals. Engine rebuilds are often uneconomical relative to the car's value.
TwinAir engine failures often involve expensive internal components including timing system, turbocharger, or MultiAir valve control system. Repair costs frequently exceed £3,000-5,000 and may approach the vehicle's value. The complexity of the engine design means diagnosis and repair require specialist knowledge. A failed TwinAir engine is often replaced rather than rebuilt.
Listen for any unusual knocking, tapping or rattling from the engine at idle and under load. Check the oil for metal particles or discolouration. On higher-mileage examples, a professional compression test can reveal internal wear before it becomes critical.
This includes doors that will not open using normal controls or will not close properly, affecting both access and security. The convertible roof mechanism and frameless door design place additional stress on door hinges, handles, and latching mechanisms compared to conventional cars. Failures typically involve door handle mechanisms, striker plates, or hinge wear.
Door operation problems affect daily usability and security. A door that will not open properly can trap occupants, while a door that will not close securely compromises vehicle security and weather protection. In extreme cases, a door that opens unexpectedly while driving poses a safety risk. Repair may involve door handle replacement, striker adjustment, or hinge replacement.
Check panel gaps are even and consistent all the way around the car. Look for signs of repainting — overspray on rubber seals, mismatched paint texture or colour differences between panels. Open and close all doors, the boot and bonnet to check alignment.

Based on 95k real DVSA MOT tests, the Fiat 500C fails more often than average on several items. The biggest outlier is suspension component damaged or corroded at 51x the fleet average, followed by body panel damage (30x).
When viewing a specific car, check its MOT history for recurring advisories in these categories. See the full Fiat 500C MOT failure breakdown for data at every mileage point.
Routine servicing (oil and filter change every 9k miles) typically costs £80–£120 at an independent garage.

The Fiat 500C 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. 2018-2020 petrol models are the most reliable with 86-89% MOT pass rates. The 2015 facelift brought improved infotainment and updated engines. Avoid 2010-2012 models and all diesel variants which have significantly worse reliability records.
