2008 Daihatsu Sirion 1.0L Petrol · CE58 OKG

The 2008 DAIHATSU SIRION presents a concerning pattern of recurring MOT failures spanning nearly two decades, with three consecutive failed tests between 2019 and 2021 followed by a partial pass in 2022 that retained multiple advisories. The latest 2022-09-08 MOT confirmed persistent issues including worn rear axle suspension components, play in the front lower suspension arm, and critical tyre safety violations that remain unresolved despite the pass result. While the most recent test did not trigger a fail, the continued presence of advisories indicates the underlying mechanical problems have not been fully resolved and the vehicle remains in a state of ongoing remediation rather than satisfactory roadworthiness. This trajectory suggests a gradual degradation of key chassis and drivetrain elements rather than an abrupt breakdown, with the failure modes centering on suspension integrity, brake system corrosion, and tyre deterioration. With 127,546 recorded miles accumulated over approximately eighteen years, the vehicle averages roughly 7,086 miles per annum, which aligns with expected usage for its age but masks the accelerated wear evident in the MOT history. The absence of a MOT test between the 2021-09-01 failure and the 2020-09-08 pass creates a six-month gap during which the car likely operated under degraded conditions, potentially allowing minor issues to compound. The mileage figure appears consistent with moderate daily use, yet the concentration of failures—particularly the recurrent rear tyre shortfalls and suspension component wear—points to significant cumulative abuse affecting consumable parts such as bushings, brake pipes, and tyre carcass integrity. When viewed against the older failure clusters in 2019 and 2020, the high mileage correlates with progressive deterioration rather than indicating excessive driving for a vehicle of this type. Focused attention should be directed at the rear axle suspension assembly where the 2022 MOT identified a worn pin or bushing on the offside rear axle and play in the front lower suspension arm ball joint, both of which are prone to developing noise and loss of control over time. During a test drive, listen for clunking or skipping over bumps, particularly through the front lower arm area, and observe whether the rear wheels exhibit any lateral tendency or uneven contact patch. The rear brake pipe history documented in 2020 and 2021 shows a pattern of corrosion and grease buildup that compromises braking performance; inspect the pipe for visible cracks, bulges, or internal leakage while the vehicle is stationary to ensure the caliper-to-pipe connection remains secure. Additionally, check the front outer drive shaft boot for signs of detachment or grease contamination that could allow lubricant to enter the differential housing. Tyre condition warrants particular scrutiny because multiple failed MOTs between 2019 and 2021 each cited dangerously short tread depths on both front and rear tyres, with one rear tyre described as excessively worn on the inner edge. A thorough visual and tactile inspection should confirm that all tyres meet the minimum 1.6mm legal requirement, paying special attention to the rears which have repeatedly triggered the maximum dangerous rating. On a test drive, press firmly on the accelerator and note any vibrations, pulling to one direction, or reduced braking effectiveness that might indicate suspension misalignment or worn bushings. Verify that all exterior lighting functions correctly since the records show multiple warning lamp failures across different years, and address any non-functional indicator lights immediately as they may signal deeper electrical system issues that could affect safety. If any of the flagged components require replacement before purchase, budget accordingly and consider having a professional mechanic perform a comprehensive chassis inspection given the persistent nature of the failure patterns.
