Reliability, common problems and owner reviews for the Dacia Bigster 1.2 TCe 130 mild hybrid (H5Dt / HR12). Check this before you buy used.
The TCe 130 in the Duster III and the Bigster is the 1,199 cc three-cylinder with a 48V starter-generator. It is not the old 1,198 cc four-cylinder that drinks oil, and it is not the Duster Hybrid 140. Auto Plus, 5 September 2026, put the early Duster III complaints on the 12V and the electronics: a dead screen, a reversing camera that stays black, parking radars and driver aids that drop out, and a stack of warnings that can vanish after a restart. On the mild-hybrid cars the same piece records no-starts with a shower of messages, at mileages still under about 26,000 km, plus a few injection faults that it does not describe further. On Dacia's own forum a 2024 1.2 TCe 130 4x4 fired and died until several tries; another owner with the same start-and-stall said an engine update stopped it. Auto Plus's gearbox stories — swarf in the oil, a complete gearbox, a gearbox computer that bricks the car — are written against the E-Tech Hybrid 140, which is a different powertrain. Buy the 130 on the 12V, the software level and a quiet cold start. Do not price it as the Hybrid 140's gearbox.
Same engine, other cars
This is the same physical engine (H5Dt) sold under different names across brands. Reliability is broadly shared — cross-check these:
Known Issues
Auto Plus: mild-hybrid Duster IIIs refuse to start and light a cluster of faults at low mileage, the highest figure they had being about 26,000 km. The screen and the reversing camera fail on the same cars, and the warnings often leave no trace after a restart, which makes the dealer visit harder. This 48V car still needs the 12V to wake the controllers. A battery that has already stranded the car once is the part to replace, not a story about a chain.
Fix / Workaround: Leave it overnight and start it cold. A no-start, a black camera or a warning pile is the pattern. Ask whether the 12V has been replaced and whether an engine update has been loaded.
0Typically appears after: 15,000 km
On communaute.dacia.fr a 2024 Duster 1.2 TCe 130 4x4 cranked, fired and stalled, and needed several tries. The first time a connected-services fault showed; the second time the screen offered an engine update after it finally ran. A reply on that thread said the same stall stopped after the petrol-engine update the car had asked for. Auto Plus adds 'a few injection faults' on this 130 without naming a part. That is not a published injector campaign and it is not an oil-burning engine.
Fix / Workaround: Three cold starts, not one warm handover. If it stalls, the car wants the engine calibration before you buy it. Do not accept 'they all do that' without the update on the invoice.
0Typically appears after: 5,000 km
Auto Plus describes swarf in the gearbox oil and complete gearbox replacements on the Duster E-Tech Hybrid 140. That is the full hybrid, not the TCe 130 mild hybrid this page is about. The old Renault 1.2 four-cylinder oil consumption is a different engine again, 1,198 cc rather than this 1,199 cc three-cylinder. A seller who bundles those stories into the price of a 130 is selling a different car's reputation.
Fix / Workaround: Read the badge. TCe 130 mild hybrid: 12V, screen, engine update. Hybrid 140: ask the gearbox questions on that car's page, not here.
0Mileage Thresholds
After 26,000 km: Auto Plus's mild-hybrid no-starts sit under about this mileage. A clean 12V and a current engine calibration matter here, not a chain replacement.
After 100,000 km: No high-mileage mechanical pattern for this 1.2 in the sources read. The oil-consumption reputation belongs to an older four-cylinder.
Pre-Purchase Checklist
- ☐Badge says TCe 130 mild hybrid, not Hybrid 140 and not Eco-G
- ☐Cold start three times: it must stay running
- ☐Screen, reversing camera and parking aids work on that same start
- ☐Engine-update level written down if it has ever stalled
- ☐12V tested after the car has sat, not just after a drive
- ☐Parking-brake recall (build 13 March 2024 to 26 February 2025) and the R107 pedal connector (cars built before 10 July 2024) are the car, not the engine — still check the VIN
