2020 Dacia Duster 1.5L Diesel · SE70 ACX

The most recent MOT history of this Dacia Duster reveals a concerning pattern of repeated failures despite no recorded defects on the test dates. The vehicle failed twice in April 2026—just 15 miles apart—before passing on the third attempt, a red flag for either administrative oversight or a persistent but undetected issue. The August 2025 tests also show a double failure at identical mileage, suggesting a recurring problem that evaded initial inspection. While the August 2024 test passed without issue, the lack of defects on any test does not account for why failures occurred in 2025 and 2026, implying either a mechanical condition that fluctuates or inconsistent testing. The trend is not improving; rather, it suggests either a lack of pre-MOT maintenance or a component prone to intermittent failure. The recorded mileage of 59,121 miles over six years equates to approximately 9,854 miles annually, which aligns with typical usage for a vehicle of this age. There are no significant gaps or rapid spikes in mileage between tests, though the 2025 and 2026 failures occurred within a narrow window—just over six months apart—without intermediate mileage progression. This suggests the vehicle was either stationary or driven sparingly during that period, which could contribute to mechanical issues if fluids were neglected or components were not regularly stressed. The consistency in mileage between tests does not explain the repeated failures, however, as the distance covered between August 2024 and April 2026 (6,901 miles) should have exposed any latent faults. Given the repeated failures without recorded defects, a buyer should prioritise a thorough inspection of the braking system, suspension components, and exhaust emissions. The double failures in 2025 and 2026 imply a recurring issue that may not have been visually apparent—potential candidates include binding brake calipers, worn suspension bushes, or failing coil springs. Corrosion in wheel arches or subframe areas should also be checked, as structural integrity is critical for safety. The lack of defects on passing tests does not rule out hidden wear; independent verification of fluid levels (brakes, power steering, engine coolant) and tyre condition is essential, particularly if the vehicle was stationary for extended periods. A pre-purchase inspection by a qualified mechanic is strongly advised to identify any intermittent faults.
