Dacia Duster
Renault's 1.2-litre turbo engine is notorious for excessive oil consumption and timing chain problems. Excessively wide piston tolerances lead to oil burning that thermally damages the exhaust valves and can ultimately result in total engine failure. Check oil level at least every 2,000 km; inspect thoroughly before purchase.
Problem engine: turbo power in the Duster
125 hp TCe in the Duster — punchy and agile. But the notorious timing chain casts a shadow. Repair costs up to €2,000 are realistic. Known issues make this engine a risk.
Engine Weaknesses 4
Oil return jets to the chain tensioner are undersized and clog. Chain stretch begins from as early as 37,000 km. Multiple replacements documented without a permanent fix.
Symptoms: Oil return jets to the chain tensioner are undersized and clog
Oil consumption up to 1.5 L/1,000 km documented. Piston rings and valve stem seals affected. Classified internally by Renault as a risk engine.
Symptoms: Oil consumption up to 1.5 L/1,000 km documented
Wastegate flap sticks or no longer closes properly. Boost pressure too low or overboost possible. Turbo replacement required.
Symptoms: Wastegate flap sticks or no longer closes properly
Water pump leaks at the shaft seal. Coolant loss can lead to overheating if not caught in time.
Symptoms: Water pump leaks at the shaft seal
Vehicle Weaknesses 6
The Duster II also shows axle components with a five-fold above-average defect rate at the very first MOT. Tie rod ends and steering joints are among the most common weak points.
The Duster II brake lines tend to corrode after four years of operation.
A recall was issued for vehicles produced June to July 2023 due to possible cable connector defects that could affect the airbag and drivetrain.
As with its predecessor, the Duster II headlights and tail lights show above-average defect rates at MOT.
Four-wheel drive vehicles develop oil leaks in the transfer case area more frequently after a few years of operation.
The front seats in the Duster II provide little lateral support. Rear seat passengers can slide out of position in corners on the barely contoured bench.
Reports & Tests
At 6–7 years old, nearly one in four has significant defects (23.5% vs. 13.6% average). Main issues: steering joints, lighting, and brakes.
3.7 to 8.4 breakdowns per 1,000 registrations (model years 2017–2020) — green rating. Breakdown frequency acceptable for a budget SUV.
