Dacia Duster (Mk3) Common Problems & Reliability
The Mk3 Dacia Duster brings significant modernization to the brand's iconic SUV, introducing hybrid powertrains and sharper styling while attempting to retain its famous value-for-money ethos. Built on the modern CMF-B platform, it offers vastly improved safety tech, refinement, and interior quality compared to its predecessors. In the UK, it continues to appeal to pragmatic buyers but now attracts those who might have previously considered mainstream rivals like the Nissan Qashqai. Reliability is expected to be strong, leaning heavily on Renault's latest hybrid and petrol powertrains. It suits modern families who want a durable, practical, and stylish SUV without paying a premium badge tax.
