Frequently asked questions
Which Nissan Primera P12 engine is the most reliable?
1.8 / 2.0 (QG18 / QR20) — Reliable verdict. The naturally-aspirated petrols — the 1.8 QG18 and the 2.0 QR20 — are the dependable, simple choice in the quirky P12 Primera: chain-driven, port-injected and largely vice-free, with the unburstable reputation that made these Nissan fours popular as taxis. Cautions are minor: the QR20 can show some oil use and the odd coil/sensor, and the CVT automatic (where fitted) is the real weak point to avoid more than the engine. On a manual, a serviced car is a genuinely low-worry, long-lived unit.
