Nissan Qashqai
Renault-Nissan 1.5 dCi diesel engine — fitted in millions of vehicles. Fundamentally solid, but EGR valve and injectors are weak points.
Pure diesel sensibility
103 hp diesel — economical and practical, but driving fun is not a criterion here.
Engine Weaknesses 6
The K9K high-pressure pump can generate metal swarf that contaminates the entire fuel system. Pump, all four injectors, fuel lines, and tank must all be replaced.
Symptoms: Engine failure, starting difficulties, black smoke, metal particles visible in fuel filter.
The K9K timing belt can break prematurely if the injection pump is not correctly aligned. Misalignment causes the belt to fray at the edge and snap well before the replacement interval. Engine damage as it is an interference engine.
Symptoms: Belt noise, visible edge wear on timing belt, sudden engine shutdown
The K9K EGR valve clogs with soot deposits, especially during frequent short-trip driving. A stuck valve causes power loss and increased consumption.
Symptoms: Power loss, rough running, increased fuel consumption, check engine light with EGR fault code.
The K9K DPF does not regenerate sufficiently during frequent short-trip driving and clogs up. First problems often arise between 50,000 and 80,000 km.
Symptoms: DPF warning light, power loss, black smoke, regeneration cycles fail, vehicle enters limp mode.
The K9K charge air hose splits frequently, especially on older build years (FE0C version). Newer FE1C versions are more robust. The hose often tears at clamps or pinch points.
Symptoms: Sudden severe power loss, hissing noise under load, increased fuel consumption, check engine light.
The K9K camshaft sensor fails repeatedly from around 100,000 km. Sporadic starting problems and rough running are the result. Aftermarket sensors often last only a short time.
Symptoms: Sporadic starting problems, engine misfires, check engine light, occasional stalling
Vehicle Weaknesses 13
Suspension components and steering joints on the J10 wear at an above-average rate. MOT reports show these items flagged significantly more often than the fleet average. Tie rod ends and ball joints are particularly affected.
The Qashqai J10 front shock absorbers fail earlier than expected. Oil leakage is a typical picture at MOT inspection and often causes test failures.
The J10 subframe and underbody start to corrode after just a few years. Forum reports show rust starting as early as 1.5–2 years. Factory underbody corrosion protection is inadequate.
The Qashqai J10 AC compressor magnetic clutch fails from around 100,000 km. AC no longer cools; full compressor replacement is often needed.
In the Qashqai J10 water enters the footwell through leaking cable gland seals or the windscreen seal. Moisture can damage ECUs.
The Qashqai J10 brake discs wear at an above-average rate despite moderate mileage. Early build years also frequently show a poorly functioning handbrake at MOT inspection.
Low beam lights, indicators, and rear lights fail on the Qashqai J10 at an above-average rate and are a recurring MOT deficiency. Bulbs and sockets are the most common fault points.
The tailgate gas struts lose pressure and no longer hold the lid open. A recall was required due to inadequate coating on the struts which caused gas leakage.
Parking sensors on the J10 fail more frequently or give false alarms. Defective sensors or wiring breaks are the most common causes, especially on older vehicles with connector corrosion.
The Qashqai J10 blower resistor burns out and the fan only runs on highest speed or not at all. Common recurring issue, replacement part is inexpensive.
The Qashqai J10 sway bar end links wear from as early as around 36,000 km. Thudding over bumps is typical. Known production issue.
The seats creak with age, and the hard plastic quality in the interior is poor. Squeaking and rattling from the dashboard area are typical complaints.
The steering column universal joint on the Qashqai J10 dries out and causes squeaking when steering. Temporarily resolved with grease; long-term replacement needed.
