2019 Dacia Logan — MOT failures & pass rate
The 2019 Dacia Logan passed 87.3% of its 10,681 recorded MOT tests. Against small family cars of a similar age (9.6% fail rate), the 2019 Logan comes out 3.2pp worse. Failures cluster in lighting & signalling, visibility and tyres.
What the MOT record shows
Lighting & signalling dominates the failure mix at 10.3% of all tests — 4.0 points clear of visibility, so it is the first thing to check.
At component level the recurring items are headlamp aim, wipers and headlamp — headlamp aim alone was recorded 822 times.
A 150k+ example is materially riskier than a 0-30k one: 23.8% versus 8.5%.
Split by fuel, diesel examples fail 4.4pp more often than petrol ones (15.7% vs 11.4%) — worth weighing if you have a choice.
Advisories point at the next bill rather than this one: tyres was flagged on 23.6% of tests without failing them.
The trend is worsening — 8.5% of tests failed in 2021 against 14.9% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2019 Logan
On a 2019 Logan, lighting & signalling is what the MOT record says goes wrong most — it appeared in 10.3% of tests. Check these areas before you commit.
- Lighting & signalling (10.3% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (6.3% 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 (3.6% 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.
