2016 Fiat 500 1.2L Petrol · PL16 HWM

The 2016 FIAT 500 passed its most recent MOT test on 9 January 2026 with no defects recorded, which represents a positive current position. However, reviewing the trajectory over the previous two years reveals a pattern that warrants scrutiny. The 2024 test introduced advisories regarding front inner brake disc wear and rear sub-frame corrosion, before the April 2024 retest identified major wear on both front suspension arm pins or bushes and dangerously worn front brake pads. The 2025 cycle then escalated further, recording dangerous wear to the rear upper shock absorber top mount bushes on both sides, alongside a clutch pedal rubber deficiency categorised as a dangerous advisory. While the latest pass is clean, the recent history suggests an accumulation of suspension, braking, and structural advisories that have only just been addressed or have not yet re-presented themselves. With a recorded mileage of 47,879 miles over approximately ten years, this FIAT 500 is averaging just under 4,800 miles annually, which is significantly below the typical usage profile for a vehicle of this age. This low annual mileage carries specific mechanical implications. Extended periods of standing or very light use commonly lead to brake caliper binding, corrosion on brake disc surfaces, and degradation of brake fluid through moisture absorption rather than active service. The 12V battery is also highly likely to have suffered reduced capacity due to repeated shallow discharge cycles, and age-related perishing or cracking of tyre rubber should be expected even if tread depth appears adequate. Coolant, brake fluid, and gearbox oil will all have degraded on a calendar basis, irrespective of the low odometer reading, and a full fluid service history should be verified. From the recorded defects, the suspension system clearly demands the most thorough physical inspection on a test drive. The worn rear shock absorber top mount bushes and the earlier failure of both front suspension arm pins or bushes indicate that the entire front and rear suspension should be evaluated for clonking, knocking, or rattling over uneven road surfaces, particularly over speed humps and during full-lock manoeuvres. Steering vagueness or uneven tyre wear, particularly on the inner or outer shoulders, would suggest that the offside front track rod end dust cover deterioration noted in 2025 has progressed, allowing contaminant ingress and joint wear. On the road, listen for creaks from the rear top mount locations under acceleration and braking, and ensure the vehicle does not drift or wander, which would indicate compromised bush integrity. Given the advisory regarding rear sub-frame corrosion, the underside of the vehicle should also be inspected on a ramp for any progression of surface rust to a structurally significant level, particularly around mounting brackets and mounting points. Braking performance should be tested with particular care given the dangerous brake pad failure recorded in 2024 and the front brake disc scoring advisory. On a test drive, expect any brake shudder through the steering wheel or a pulsing pedal under firm application, which would indicate lateral disc runout resulting from the previously noted wear or from corrosion due to standing. Inspect the front discs directly for a pronounced lip on the outer edge and for surface pitting or scoring. The clutch pedal rubber absence recorded as dangerous is a minor but important physical and safety deficiency, allowing foot slippage; ensure this has been correctly replaced. Additionally, examine the sidewalls of all four tyres for cracking, crazing, or perishing consistent with age rather than mileage, verify all registration plate lamps are fully operational, and confirm evidence of recent brake fluid, coolant, and gearbox oil replacement in line with calendar intervals, as the odometer alone will not reflect the true service requirement for any of these fluids.
