Reliability, common problems and owner reviews for the Nissan Qashqai II 1.5 / 1.6 dCi (K9K / R9M). Check this before you buy used.
The diesels are the high-mileage J11 Qashqai choice — the frugal 1.5 dCi (K9K, the ubiquitous Renault-Nissan small diesel) and the stronger 1.6 dCi (R9M, shared with the Mégane/Kadjar). Both are economical and proven; standard cautions apply: DPF clogging on short trips, EGR sooting, injector wear, the K9K timing belt (do it on schedule), and AdBlue on later cars. The 1.6 is better-matched to the crossover's weight. A motorway-driven, on-schedule car is a dependable long-hauler — buy on belt, DPF and injector history.
