2020 Fiat 500 Rockstar Mhev 1.0L Petrol · YR12 SHA

The most recent MOT test on 22 December 2025 confirms the vehicle remains roadworthy, though with critical tyre-related advisories that demand immediate attention. The trend over the past three tests shows a deterioration in tyre condition, with the December 2025 failure to meet legal limits on tread depth and evidence of perishing and cracking on both rear tyres. This contrasts sharply with the clean passes in 2023 and 2024, where no defects were recorded, suggesting a recent lapse in tyre maintenance or a failure to replace worn components in a timely manner. The November 2023 failure, just one mile before the subsequent pass, further highlights a pattern of neglect in tyre upkeep—front tyres suffered structural separation, a serious risk of sudden blowout. The recorded mileage of 32,781 miles over five years and nine months indicates unusually low usage, averaging just over 5,400 miles annually. This suggests the vehicle has spent extended periods either stationary or lightly utilised, which can accelerate wear on suspension bushes, coil springs, and brake calipers due to lack of motion. The gap between the 2023 failure and the following pass—just one mile apart—implies the test was conducted after a tyre replacement, yet the new tyres were not properly inspected or rotated, as evidenced by the rapid re-emergence of edge wear. Such low mileage also raises questions about fluid changes—brake fluid, power steering, and differential oil—components that degrade over time regardless of distance travelled. A buyer should prioritise a thorough inspection of all four tyres, focusing on the rear set, which now show signs of perishing and cracking. The front tyres, previously failed for structural separation, should be examined for residual weaknesses or uneven wear patterns that might indicate alignment issues or improper mounting. Given the low mileage, attention must also be given to suspension components—check coil springs for corrosion or fatigue, and inspect bushes for dryness or excessive play, as prolonged inactivity can embrittle rubber. The braking system warrants scrutiny: binding calipers or seized wheel cylinders were not flagged in past tests, but the lack of recent use may have allowed moisture ingress or brake fluid degradation, potentially compromising stopping performance. Finally, verify the MHEV hybrid system’s cooling and battery health, as hybrid vehicles are prone to thermal and electrical failures when left unused for prolonged periods.
