The picture
The Dacia Logan is a family of automobiles produced and marketed jointly by the French manufacturer Renault and its Romanian subsidiary Dacia since mid-2004, and was the successor to the Dacia 1310 and Dacia Solenza. It has been produced as a sedan, station wagon, and as a pick-up.
MOT data from 18,827 tests puts this car on a 75.6% first-time pass rate, roughly in line with the UK fleet average. Average mileage at test is 66,437 miles. The most common fail item is failed number plate light, followed by tyre tread below the legal limit.
Buyers weighing up a used Logan should treat the failure breakdown as a pre-purchase checklist. The pass rate is reasonable, but the gap between first attempt and a clean sheet narrows with age and mileage.

Year-band analysis
First-time MOT pass rate split by registration band. A 5.0-point gap between bands means the year you buy Dacia Logan has a real effect on what turns up at the garage.
Best band to buy
79.0%
2018–2020 registration
the 2018–2020 band climbs to 79.0% — a 5.0-point improvement. Tests in this band average 48,776 miles — roughly 36K miles fewer on the clock than the older band. Failures here are mostly wear items: inoperative in the case of multiple lamps…, does not clear the windscreen effectively — the structural issues that drag down older examples don't appear in the top-10 for this band. The stricter post-2018 MOT test rules meant manufacturers had to tighten up emissions and electrical checks, but this band still shows far fewer major failures on suspension and bodywork than the older fleet.
Band to be cautious about
74.0%
Pre-2018 registration
On the older band (pre-2018), the data shows a 74.0% pass rate against a fleet average of 79.0% on the newer band. The main culprits logged at test: inoperative in the case of multiple lamps…, tread depth below requirements of 1.6mm, and ball joint excessively worn. Average mileage on test for this band is 85,044 miles — high-mileage wear items are a recurring theme.
Best band to buy: 2018-2020 (79.0% first-time pass). Worst band to avoid: pre-2018 (74.0% pass). That's a 5.0-point spread across 18,604 older tests and 6,369 newer ones — year of build makes a material difference on this model.

Recall history
The Logan has 9 official UK vehicle recalls covering defect details, remedies, and affected build dates.
Use the failure ranking as a pre-test checklist or a haggling lever. Treat the headline pass rate as a fleet-wide trend, not a guarantee on any individual car.
If you own a Logan and your last MOT looked nothing like the ranked failures above, that's normal — individual cars vary widely. The ranking shows the patterns testers flag most often across the country.
