2021 Dacia Duster SE Twenty TCE 4X2 1.3L Petrol · PX21 ONN

The vehicle remains roadworthy as of its most recent MOT on 2026-03-20, but the maintenance trend is clearly worsening. The tester flagged three tyre-related defects — all tyres perishing, and both front tyres worn to the legal limit on the inner edge — which indicates a failure to maintain tread depth and tyre condition. These are not minor issues; they represent a significant safety risk and suggest the previous owner either neglected tyre replacement or allowed the tyres to degrade beyond acceptable limits. The fact that these defects appeared in the most recent test, despite no issues in 2025-03-05, signals a deterioration in upkeep rather than a one-off oversight. The mileage history reveals a very low annual usage profile — approximately 2,379 miles per year over five years — which is unusually low for a 2021 model. The jump from 7,226 miles in March 2024 to 9,419 miles in March 2025, then to 11,895 miles in March 2026, suggests the vehicle was stationary for long periods, possibly stored or used infrequently. This low usage may explain why some components like suspension bushes or brake calipers have not yet shown wear, but it also increases the risk of rubber degradation, battery drain, and brake caliper binding due to lack of movement. The gap between MOTs is consistent, with no signs of sudden mileage spikes, which supports the idea of steady, low-mileage ownership. A buyer should inspect the tyres immediately — all four should be replaced before the next MOT, as the current ones are legally unsafe. The nearside rear tyre with a nail in 2024 may have been repaired, but the presence of a nail suggests possible structural damage or a history of punctures that could have compromised the tyre’s integrity. Brake systems should be checked for binding or corrosion, especially since the front brakes were flagged for wear in the most recent test — this could indicate uneven wear or poor maintenance. Suspension components, particularly the rear coil springs and bushes, should be examined for signs of sagging or cracking, as low mileage often masks structural fatigue from prolonged inactivity. The exhaust and underbody should also be inspected for corrosion, as infrequent use can lead to moisture buildup and rust in vulnerable areas. Overall, the vehicle’s mechanical condition is acceptable for immediate use, but the tyre condition and maintenance pattern demand urgent attention. The low mileage is not a guarantee of mechanical health — it can mask other risks like degraded fluids, seized components, or electrical issues. A thorough pre-purchase inspection should focus on tyres, brakes, suspension, and corrosion, especially around the wheel arches and exhaust system. The MOT record shows a clear decline in upkeep over the last 12 months, which should factor into any purchase decision.
