3rd gen · 2024–present
1.0 ECO-G LPG bi-fuel · 100 hp · 1.2 TCe mild hybrid · 130 hp · 1.6 E-Tech full hybrid · 140 hp
Known problems
- Good to know
1.0 ECO-G LPG boot space and range trade-off
Symptoms: reduced luggage space and shorter per-tank range from the additional gas tank
What to do: This is a design trade-off rather than a fault; the LPG tank cuts boot volume, so factor that in if you carry a lot of luggage.
- Good to know
Limited long-term reliability history
Symptoms: no established high-mileage track record yet for the new mild-hybrid and full-hybrid drivetrains
What to do: The body and running gear are proven Dacia, but the 1.2 mild-hybrid and 1.6 E-Tech hybrid are newer; keep to the service book and watch early recall notices while the model builds history.
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 severe/short-trip use. |
| LPG filter & system inspection (ECO-G) important | every 12,000 mi (20,000 km) | — |
| Air filter | every 19,000 mi (30,000 km) | — |
| Spark plugs (petrol/LPG) | every 25,000 mi (40,000 km) | — |
| Brake fluid important | every 36 months | — |
| Timing chain important | — | The 1.2 mild-hybrid and 1.6 hybrid petrol units are chain-driven. |
2nd gen (HM) · 2018–2023
1.0 ECO-G LPG bi-fuel · 100 hp · 1.0 TCe · 100 hp · 1.3 TCe · 150 hp · 1.5 dCi · 115 hp · 1.6 SCe · 115 hp
Known problems
- Worth watching
1.3 TCe intercooler / boost pipe popping off
Symptoms: sudden loss of power under acceleration, limp mode, boost-related fault codes
What to do: The factory single-use clamps on the intercooler pipes can lose grip; if you get intermittent limp mode under boost, have the charge pipes and clamps checked and reclamped.
- Worth watching
1.5 dCi DPF and AdBlue faults
Symptoms: DPF clogging on short trips, plus AdBlue/SCR warnings sometimes from sensor faults
What to do: Drive the diesel on longer runs to regenerate the DPF; if AdBlue warnings appear with a full tank, suspect a sensor or crystallised fluid rather than low level.
- Worth watching usually 12,000–50,000 mi (20,000–80,000 km)
Front strut-mount and steering wear
Symptoms: knocking from the front over bumps, vague steering; tie-rod ends and strut mounts wearing early
What to do: Have the upper strut mounts/bearings and tie-rod ends checked from fairly low mileage; they are undersized for the car and wear sooner than expected.
- Good to know
Infotainment and electrical faults
Symptoms: media-system glitches, occasional warning lights, connectivity dropouts
What to do: Many are resolved by a dealer software update; keep the infotainment firmware current.
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 severe/short-trip use; the 1.3 TCe direct-injection turbo benefits from cleaner oil. |
| LPG filter & system inspection (ECO-G) important | every 12,000 mi (20,000 km) | — |
| Air filter | every 19,000 mi (30,000 km) | — |
| Spark plugs (petrol/LPG) | every 25,000 mi (40,000 km) | Turbo TCe and LPG running shorten plug life. |
| Brake fluid important | every 36 months | — |
| Timing chain (TCe and SCe) important | — | The 1.0/1.3 TCe and 1.6 SCe are chain-driven; the 1.5 dCi is belt-driven — replace the diesel belt on schedule. |
1st gen (HS) · 2010–2018
1.2 TCe · 125 hp · 1.5 dCi · 110 hp · 1.6 16V · 105 hp · 1.6 SCe · 114 hp
Known problems
- Worth watching
1.5 dCi diesel particulate filter clogging
Symptoms: DPF warning, reduced power and repeated regenerations on short urban journeys
What to do: The diesel needs regular higher-speed runs to burn off soot; if you mostly drive short trips, budget for forced regens or pick a petrol Duster.
- Worth watching
Cooling fan / overheating in slow traffic
Symptoms: temperature climbing in stop-start traffic, sometimes traced to a blown cooling-fan fuse
What to do: If the gauge rises in traffic, have the cooling fan, its fuse and the thermostat checked; catching it early avoids head-gasket damage.
- Worth watching usually from 50,000 mi (80,000 km)
Suspension and wheel-bearing wear
Symptoms: clunks over bumps, droning wheel-bearing noise, worn bushes on higher-mileage cars
What to do: Have the wheel bearings, bushes and drop links checked at service; they are routine, inexpensive wear items on a car often used on rough roads.
- Good to know
Electrical niggles and dashboard warnings
Symptoms: intermittent warning lights, lighting glitches and minor electrical faults, more common on early cars
What to do: Most are connector/earth or sensor issues rather than serious faults; check earliest 2010-2013 cars more carefully.
Service schedule

|---|---|---|
| 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 severe/off-road/short-trip use. |
| Air filter | every 19,000 mi (30,000 km) | — |
| Diesel fuel filter (1.5 dCi) | every 19,000 mi (30,000 km) | — |
| Spark plugs (petrol) | every 37,000 mi (60,000 km) | 1.2 TCe turbo runs a shorter ~40k interval. |
| Timing belt (1.6 16V and 1.5 dCi) / chain (1.2 TCe, 1.6 SCe) critical | every 56,000 mi (90,000 km) | The K4M 1.6 16V and K9K 1.5 dCi are belt-driven interference engines — a snapped belt bends valves; the H4M/H5Ft use chains. |
| 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.
