Nissan Pathfinder R51-FL
Weaknesses, engine ratings and buying advice
The Pathfinder R51 facelift (2010–2014) is the revised version of the Navara-based ladder-frame SUV. The rugged off-roader concept stays, as do selectable low-range four-wheel drive, the towing capacity and seating for up to seven. In this phase the engine range focused on diesel: the continued 2.5-litre YD25DDTi (now up to 190 hp) plus the larger V9X 3.0 V6 diesel with 231 hp, which moves the heavy SUV noticeably more easily and smoothly than the strained four-cylinder and turns it into a usable long-distance cruiser.
In the Pathfinder the V9X is a pleasant touring engine with plenty of torque, but it is no fit-and-forget unit: clean maintenance, diligent oil changes and an eye on the injectors and EGR are mandatory, and its repairs cost more than the YD25's. The YD25 in turn brings the family's known weaknesses: timing-chain stretch with cold-start rattle and the cracking EGR cooler that can let coolant into the combustion chamber. Disappearing coolant with no visible leak is the warning sign here too, and one to take seriously.
And of course the facelift shares the platform's frame-rust issue. The ladder frame can rot through in its box sections — barely visible from outside on the closed SUV, which is why inspection from underneath is indispensable, especially on vehicles from salted regions. With age come the typical electrical and air-conditioning issues, though these are manageable.
Buying advice: Onto the lift first, then the test drive. Check the frame, crossmembers and underbody for rot, probing if in doubt. On the YD25, check the coolant level and EGR history and listen for chain rattle on cold start. On the V9X, watch for an even idle, smoke behaviour and stored faults, and verify a complete service history. Try the four-wheel-drive system including low range, the air conditioning and the electrics.
Verdict: The R51 facelift is the more mature Pathfinder — especially with the smooth V9X V6, which gives the heavy off-roader tolerable muscle. But as with all Navara and Pathfinder models on this platform, the frame's condition decides between purchase and goodbye. A dry, well-kept example with a healthy chassis and clean engine history is a solid, off-road-capable family SUV; frame rust, by contrast, makes it an economic risk.

Engine Overview
The Nissan Pathfinder R51-FL is available with 2 engine variants — from 171 to 280 hp.
Strong 2.5-litre four-cylinder turbodiesel with around 174 to 190 hp — built for rugged commercial duty, with hefty torque and a long stride. Fundamentally a workhorse, but not without pitfalls. The simplex timing chain stretches or can snap and needs regular checking; a skipped chain ends expensively. The turbo bearing wears with mileage and announces itself through whistling and oil use, while the EGR cooler tends to leak and causes creeping coolant loss. Keep an eye on the timing chain, turbo and cooling system and change the oil consistently, and this diesel goes the distance.
- !! Simplex timing chain breaks/stretches from 140,000 km
The lower timing chain was reduced from duplex to simplex while engine output increased by 50%, leading to premature stretch and in the worst case chain breakage. Upgrade to duplex chain is possible (Billcarengineering).
Symptoms: Rattling and metallic ticking near the high-pressure pump/crankshaft area, engine warning light, poor cold start - !! Turbocharger bearing wear from 160,000 km
The YD25DDTi turbocharger tends to develop bearing wear at high mileage or with neglected oil changes. Severe turbo damage can cause secondary engine damage.
Symptoms: Whistling noise from turbo, blue smoke, power loss, oil in intercooler - !! EGR cooler leaking / coolant loss from 120,000 km
The YD25DDTi EGR cooler can develop leaks and allow coolant into the intake tract. Coolant loss without visible external leak is a typical symptom. If left untreated, overheating and engine damage follow.
Symptoms: Slow coolant loss, white smoke under acceleration, sweet smell in engine bay
+ 1 more engine weaknesses + vehicle weaknesses
Cultivated 3.0-litre V6 common-rail turbodiesel with around 231 hp — effortless pull, silky running and ample torque for relaxed cruising. A pleasant drivetrain, but not a cheap one to run. The particulate filter clogs in short-trip use and needs regular long runs to burn off, while the turbo bearing wears with mileage and signals itself through whistling and oil consumption. The fuel pump is among the costlier failure candidates. Drive this V6 the way it likes, use quality oil and keep to the service intervals, and it rewards with upmarket refinement — skimping on care bites back sharply here.
- !! Turbocharger bearing wear from 150,000 km
The turbocharger of the V9X 3.0 V6 dCi wears at higher mileages. Typical signs from 120,000–180,000 km. Turbo repair on this V6 diesel is particularly expensive.
Symptoms: Whistling turbo noise, power loss at high load, blue smoke, oil in intercooler - !! Fuel pump failure from 120,000 km
The electric fuel pump of the V9X fails between 100,000 and 150,000 km. The engine fails to start or runs erratically. Risk of breakdown.
Symptoms: Engine fails to start, irregular running, sudden power loss, breakdown - !! DPF blockage from short-trip use from 80,000 km
The V9X DPF blocks particularly quickly under short-trip use. Problems are documented from 60,000 km. The heavy SUV (Pathfinder) is often used in urban traffic, making regeneration difficult.
Symptoms: DPF warning light, power loss, increased fuel consumption, limp mode
