2020 Ssangyong Musso 2.2L Diesel · RK20 AAJ

The most recent MOT tests on this 2020 SSangYong Musso, conducted just five months ago on 25 February 2026, reveal a concerning inconsistency rather than a stable roadworthiness trend. The vehicle failed the first test at 42,032 miles before passing the subsequent retest on the same day—an unusual outcome that suggests either a temporary oversight in the testing process or a last-minute repair to address an undocumented issue. The lack of recorded defects across all prior tests, including the 2025 and 2024 examinations, implies that while the vehicle has not suffered catastrophic failures, it has never been subjected to a thorough mechanical review beyond the minimum MOT requirements. This pattern raises questions about whether critical components—such as suspension bushes, coil springs, or brake calipers—have been systematically inspected or replaced, despite the vehicle’s age and mileage. The recorded mileage progression of approximately 7,000 miles annually aligns with typical usage patterns for a vehicle of this age, though the absence of intermediate MOTs between 2024 and 2025 is notable. The gap between the 2024 test at 31,326 miles and the 2025 failure at 36,916 miles—just 15 months later—suggests either a deliberate delay in testing or a period of reduced mileage accumulation. The subsequent rapid return to testing in early 2025, followed by another 15-month interval before the 2026 tests, indicates inconsistent maintenance scheduling. This irregularity could imply that the vehicle was either stored for extended periods or driven sporadically, potentially accelerating wear on components like tyres, fuel systems, or battery health. Given the lack of documented defects across multiple MOTs, a buyer should prioritise an independent inspection of high-wear areas that are not routinely checked during standard MOT testing. The suspension system—particularly the rear bushes and coil springs—should be examined for uneven wear or corrosion, as these components are prone to gradual degradation over 6,000 miles of annual use. Brake discs and calipers, while not explicitly failed, warrant scrutiny for binding or excessive lateral wear, especially if the vehicle has experienced uneven mileage patterns. Additionally, the exhaust system should be inspected for leaks or corrosion, as older vehicles often develop hidden rust in underbody components. Finally, the battery and electrical connections should be tested, as prolonged periods of inactivity can lead to sulfation or terminal corrosion, which may not be evident during a basic MOT. The absence of advisories in past tests does not guarantee these areas are in optimal condition.
