2012 Mitsubishi ASX 1.8L Diesel · NX12 YJD

The vehicle presents a concerning roadworthiness profile characterized by a worsening trend in structural corrosion and mechanical wear. While it passed its last recorded MOT in March 2023 at 134,709 miles, this record is now over three years old, leaving the current state of the vehicle unverified. The failure in February 2023 revealed multiple critical issues, including imbalanced brakes and a major exhaust leak, indicating that maintenance was only addressed in response to failure rather than through preventative care. The recorded mileage of 134,709 miles over 14 years reflects a consistent annual usage pattern of approximately 9,600 miles. However, the interval of data shows a significant drop in vehicle quality standards between February 2022 (120,119 miles) and March 2023 (134,709 miles). During this 14,000-mile period, the vehicle transitioned from having minor advisories on aged components to failing a test with multiple serious defects, suggesting the vehicle is reaching a stage where heavy components are nearing their end of life simultaneously. A physical inspection must prioritize the structural integrity of the rear sub-frame and front wishbones, which have been flagged for corrosion across three consecutive years. The tester noted that the rear sub-frame was corroded but not yet weakened in 2023, but rust on these components accelerates without intervention. The buyer should also examine the rear trailing arm bushes and anti-roll bar bushes, which have shown a history of separation and will negatively affect handling and cause uneven tyre wear. The braking system requires further scrutiny, as the engine oil leak noted in 2023 needs immediate investigation to determine if it is a persistent gasket or seal. Given the history of corroded brake pipes and fluctuating service brakes, a full pressure test of the hydraulic lines is necessary to ensure no hidden thinning has occurred. The lack of a MOT record since 2023 significantly increases the risk that these recurring issues have deteriorated into costly mechanical failures.
