2009 Fiat 500 1.2L Petrol · ML58 WXB

A pattern of recurrent chassis and braking failures defines the 2009 FIAT 500's roadworthiness history, with the most recent September 2023 MOT passing only after addressing persistent rear coil spring corrosion, oil misting within the front suspension system, and ongoing deterioration of the rear subframe and front suspension arm bushings. Despite this final clearance, the record shows a troubling oscillation between passes and failures spanning seven years, indicating that underlying structural weaknesses have resurfaced rather than been resolved. The latest test result confirms that while the vehicle cleared the MOT standard, it carries multiple active advisories that point to systemic reliability concerns rather than isolated incidents, suggesting the car has accumulated cumulative damage that may not yet be reflected in its current certificate. The mileage figure of 100,401 miles for a seventeen-year-old vehicle translates to approximately 5,906 miles per year, which appears lower than expected for a car of this age and raises questions about the typical wear patterns associated with such driving distances. This unusually low odometer reading could indicate extended periods of storage or infrequent use, but it does not necessarily align with the severity of the reported defects. The gap between the August 2023 failed test and the subsequent September 2023 successful MOT is merely twenty-eight days, suggesting that the vehicle remained under scrutiny for just one month before clearing, yet the continued presence of rear subframe corrosion and front suspension issues implies that the underlying degradation has progressed independently of the immediate test cycle. Such a discrepancy between low recorded mileage and widespread mechanical advisories warrants particular attention when evaluating long-term reliability. Focused examination of the documented failures reveals three critical areas requiring immediate investigation during a test drive. The rear coil springs have shown consistent corrosion on both sides across two separate MOTs, and their continued presence alongside new oil misting in the front side-shock absorbers indicates potential hydraulic system contamination that could compromise braking performance and handling stability. The rear subframe has suffered corrosive damage throughout its history, with the 2023 record noting it remains "not seriously weakened" despite the extensive rust noted previously, meaning structural integrity is compromised enough to risk progressive failure. Additionally, the front suspension arm ball joints have exhibited varying degrees of wear and play across multiple assessments, and the front suspension arm pins or bushings have shown signs of fatigue that could manifest as knocking noises over bumps or loss of control during corners. For a prospective buyer, the most pressing mechanical checks should centre on the rear coil spring assembly and the front suspension linkages, as these directly impact safety-critical functions. When testing drive, listen for any metallic knocks or clunks over speed bumps, particularly through the rear axle, since corroded coil springs can transmit vibrations and lose load-bearing capacity. Inspect the front suspension arms for visible play at the ball joints by gently wiggling them while the vehicle is moving; excessive movement here would confirm the wear noted in the 2021 and 2022 MOT reports. The rear subframe should be examined for any structural flexing or cracks, especially around the rear wheel arches where corrosion has been documented repeatedly. Finally, verify the condition of the front brake discs and pipes, as historical failures included imbalance and missing support clamps, and ensure the front headlamps are securely mounted and properly aligned, since the 2021 and 2022 records highlighted multiple headlamp security concerns that could affect night-time visibility and lighting consistency. While the September 2023 MOT granted clearance, the persistence of these specific failures means the vehicle requires thorough physical verification before committing to purchase.
