2009 Mazda 3 1.6L Diesel · YB09 BHA

The 2009 Mazda 3 presents a mixed mechanical picture across its MOT history, with a pattern of intermittent failures interspersed between passes that suggests ongoing reliability rather than outright breakdowns. The most recent test on 2022-01-20 returned a passing result, yet the overall record reveals three distinct failure events—most notably the 2019 failure involving a severely cut front tyre and the 2017 failure also linked to a non-functional rear registration plate lamp—which indicate persistent underlying issues that were not fully resolved before the vehicle reached its current age. Between these setbacks, several other advisories such as minor registration plate lamp insecurity and power steering fluid deficiency have been recorded, creating a narrative of a car that experienced repeated minor systems failures rather than catastrophic damage, though the severity of the 2019 tyre failure warrants particular attention given the extent of the damage to the front tyres. At 17 years old with 135,694 miles recorded, the vehicle accumulates approximately 7,982 miles annually—a rate consistent with normal driving patterns for its model year and not indicative of unusually high or low usage. There are no significant gaps in the MOT testing schedule that would suggest extended lay-up periods, as tests were conducted each year from 2016 through 2022, including two consecutive failed years (2017 and 2019) followed by a pass in 2022. However, the distribution of failures shows that while the car generally held up between incidents, certain components required remedial work that may still be present, particularly where the 2019 failure involved structural damage to the tyres reaching the ply or cords, potentially affecting handling and safety. The absence of critical system failures since 2022 does not guarantee current reliability, especially given the prior instances where braking surfaces showed pitting and rear suspension linkage ball joints exhibited play. Buyers should pay close attention to the suspension bushings and rear road wheels, as the 2022 MOT specifically noted slight distortion on the nearside rear tyres, a condition that could manifest as a vague pulling sensation during cornering or increased vibration when travelling at speed. The power steering fluid level being below minimum in late 2021 suggests potential lubrication issues that might become more pronounced under heavy use; a leak or inadequate fill should be verified immediately. The 2018 test revealed pitting on the brake discs and play in the rear anti-roll bar linkage ball joint, meaning the driver should monitor for any shuddering or vibration through the rear suspension when accelerating or turning, and ensure the brake discs remain within safe thickness limits despite their general scoring appearance. Additionally, the obscured engine covers and under-tray components from the 2018 test point to potential water ingress or debris accumulation that could affect electrical connectivity and cooling efficiency, so a visual inspection of these areas is advisable before committing to the purchase.
