3rd gen · 2021–present
1.0 ECO-G LPG bi-fuel · 100 hp · 1.0 SCe · 65 hp · 1.0 TCe · 90 hp
Known problems
- Critical
Battery-terminal / alternator short-circuit recall
Symptoms: risk of the positive battery lead contacting the alternator, causing a short and possible fire
What to do: Check the car's VIN against Dacia's recall records and confirm the battery-terminal rework was carried out.
- Worth watching usually from 37,000 mi (60,000 km)
Premature clutch and dual-mass flywheel wear
Symptoms: clutch slip or judder, sometimes needing replacement well before 100k km
What to do: The clutch is more stressed on LPG cars and in stop-start use; have it inspected if you feel slip, and expect the dual-mass flywheel may need replacing with it.
- Good to know
Intermittent electrical and warning-light faults
Symptoms: random dashboard warnings, A/C, keyless or media faults that come and go
What to do: Note when a fault occurs to help diagnosis; many are software or connector issues resolved by a dealer update rather than a mechanical fault.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Cabin filter | every 9,000 mi (15,000 km) | — |
| Engine oil & filter change | every 9,000 mi (15,000 km) or 12 months | Halve for short-trip / severe use; the small TCe turbo relies on clean oil for its timing-chain oil jet. |
| LPG filter & system inspection (ECO-G) important | every 12,000 mi (20,000 km) | Change the gas filter and check the reducer/lines periodically on the bi-fuel car. |
| Air filter | every 19,000 mi (30,000 km) | — |
| Spark plugs | every 25,000 mi (40,000 km) | Petrol/LPG; LPG running can foul plugs a little faster. |
| Brake fluid important | every 36 months | — |
| Timing chain (1.0 TCe) important | — | Chain-driven; longevity depends on oil quality and interval discipline. |

0.9 TCe · 90 hp · 1.0 SCe · 73 hp · 1.2 16V · 75 hp · 1.2 16V LPG bi-fuel · 84 hp · 1.5 dCi · 90 hp
Known problems
- Worth watching
1.5 dCi diesel particulate filter clogging
Symptoms: DPF warning light, reduced power, forced regenerations on mostly short/urban journeys
What to do: The diesel needs regular longer runs to regenerate the DPF; if used only for short trips, budget for periodic forced regens or choose the petrol/LPG instead.
- Worth watching
Clutch slave-cylinder failure (manual)
Symptoms: spongy or dropping clutch pedal, difficulty selecting gears
What to do: If the clutch pedal feel changes, have the concentric slave cylinder inspected; it is a known failure on pre-2018 manual cars.
- Worth watching
Easy-R automated manual jerky shifting
Symptoms: hesitation and jerky, delayed gear changes when pulling away or in traffic
What to do: A dealer software update was released to smooth the shifts; if a used car still shifts harshly, have the clutch actuator and software revision checked before buying.
- Worth watching usually from 37,000 mi (60,000 km)
Front lower-arm bush and suspension wear
Symptoms: clunking over bumps, uneven front tyre wear, vague steering
What to do: Have the front control-arm bushes and drop links checked at service; they are inexpensive wear items on this car.
- Worth watching usually from 56,000 mi (90,000 km)
0.9 TCe timing-chain rattle
Symptoms: metallic rattle on cold start-up from the front of the engine
What to do: Keep to strict oil-change intervals with the correct grade; if a cold-start rattle appears, have the chain and tensioner inspected before the chain stretches further.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Cabin filter | every 9,000 mi (15,000 km) | — |
| Engine oil & filter change | every 9,000 mi (15,000 km) or 12 months | Halve for short-trip / severe use; the 0.9 TCe turbo especially benefits from cleaner oil. |
| LPG filter & system inspection (bi-fuel) important | every 12,000 mi (20,000 km) | Bi-fuel cars need the gas filter changed and the tank/lines checked periodically. |
| Air filter | every 19,000 mi (30,000 km) | — |
| Spark plugs | every 37,000 mi (60,000 km) | Petrol only; the 0.9 TCe turbo runs a shorter ~30-40k interval. |
| Timing belt (dCi and older petrol) / chain (0.9 TCe) critical | every 56,000 mi (90,000 km) | 1.5 dCi and 1.2 16V are belt-driven — replace on schedule to avoid valve damage; the 0.9 TCe uses a chain. |
| Brake fluid important | every 36 months | — |
Manufacturer-declared fuel economy
No manufacturer-declared figures for this model are in the Knowledge Base yet. A figure without the cycle it was measured under is not comparable to anything, so we publish none rather than a number you cannot interpret.
