2021 Dacia Duster Prestige Tce 4X2 — MOT failures & pass rate
The 2021 Dacia Duster Prestige Tce 4X2 passed 93.9% of its 409 recorded MOT tests. That is 2.6 percentage points better than all cars of a similar age, which fail at 8.7%. Failures cluster in lighting & signalling, visibility and tyres.
What the MOT record shows
No single area dominates — lighting & signalling (3.4%) and visibility (2.7%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, wipers and individual direction indicators — headlamp aim alone was recorded 13 times.
Tyres is the most common advisory, noted on 17.1% of tests — work that passed today but is likely due soon.

What to check before buying a 2021 Duster Prestige Tce 4X2
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 3.4% of tests. Start there.
- Lighting & signalling (3.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (2.7% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
- Tyres (2.2% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
