2015 Mitsubishi ASX 1.6L Petrol · SC65 TXB

The latest MOT test for the 2015 Mitsubishi ASX was conducted on 2025-11-29, resulting in a passing outcome, though it did not entirely mitigate the previous failures observed in November 2024 and November 2023. The trend over the past two years shows a pattern of recurring issues, particularly with corrosion affecting all four brake pipes and front suspension ball joints, which have been flagged as either major or advisory defects. The 2023 failure for exhaust emissions also highlights a persistent problem with the vehicle’s catalytic converter or lambda sensor, indicating either ongoing engine management issues or a need for deeper diagnostics. While the 2025 test cleared these concerns, the consistent presence of these advisories suggests that the vehicle has not been fully addressed in previous servicing, leaving potential long-term risks such as brake pipe failure or suspension component wear progression. The recorded mileage of 63,699 miles for a vehicle aged approximately 11 years represents a relatively low annual usage rate of around 5,791 miles per year, which is unusually low for its age. This discrepancy could imply periods of prolonged inactivity, such as storage or infrequent use, which often exacerbates wear-related issues like corrosion, tyre perishing, and fluid degradation. However, it also raises questions about whether the vehicle has been subjected to excessive static stress, particularly in areas prone to standing corrosion—such as brake pipes, suspension components, and undercarriage elements—where moisture and lack of movement accelerate deterioration. A more typical annual mileage for a 11-year-old ASX would be closer to 10,000 to 15,000 miles, which would have distributed wear more evenly across consumables and moving parts. Given the recurring MOT advisories and the vehicle’s age and mileage profile, prospective buyers should conduct a thorough physical inspection to address the immediate and potential long-term risks. The corroded brake pipes, particularly the near and offside rear pipes, are critical failures that could lead to catastrophic brake failure if left unaddressed. Inspect the brake pipes for signs of internal corrosion or leaks, and ensure all brake hoses and lines are securely fitted and free from damage. During a test drive, listen for any unusual brake pulsation or shuddering, which may indicate warped discs or binding calipers, and check for uneven brake pad wear or excessive heat buildup. The front suspension ball joints with slight play noted in previous tests should be inspected for excessive wear or binding, as this can lead to steering instability or suspension failure; look for clunking noises when driving over bumps or uneven surfaces. For the front track rod ends, which also showed slight play, buyers should verify their condition by checking for excessive movement at the ball joints and inspecting for signs of wear or cracking in the rubber bushings. The near-side rear tyre showing slight cracking or perishing is a red flag for potential sidewall damage, which can compromise tyre integrity and increase the risk of sudden blowouts. Inspect the tyre for any signs of bulges, delamination, or internal damage, and ensure the tread depth meets legal requirements. Additionally, given the vehicle’s age and low mileage, buyers should check for tyre sidewall perishing due to prolonged exposure to the elements, which can weaken the tyre structure over time. The 12V battery should be tested for charge retention and overall health, as low-mileage vehicles often suffer from battery degradation due to prolonged disuse. Finally, since the exhaust emissions issue from 2023 remains unresolved, a professional diagnostic check of the engine management system is essential to confirm whether the lambda sensor or catalytic converter requires repair or replacement. For fluid servicing, consider checking the brake fluid for moisture contamination, as standing brake systems can lead to fluid degradation, and ensure all other fluids such as coolant and transmission fluid are within their service intervals, even if the vehicle has not been driven extensively.
