What to look out for
Serious issue
Inspect the boot for splits or grease contamination on the arm.
Front Lower Control Arm Ball Joint Wear
The front suspension uses a double-wishbone-derived layout with a compression-loaded ball joint pressed into the lower control arm. The ball joint stud seats in a tapered bore in the steering knuckle and carries the full vertical and lateral cornering loads of the front axle. As the joint's polymer bearing and grease seal deteriorate — accelerated by road contamination and the absence of a grease nipple on many units — the stud develops radial and axial play, which manifests as clunking and eventually causes wandering steering geometry. A failed ball joint can separate under load, resulting in immediate loss of steering and wheel collapse.
What you would notice
Costly issue
Inspect rubber compound for cracking, extrusion from the sleeve, or oil seepage from hydraulic bushes.
Rear Multi-link Suspension Bush Collapse
The Murano rear suspension uses a multi-link geometry with five rubber-bonded bushes per side controlling toe, camber, and trailing arm compliance. The bushes are hydraulically damped on some pivot locations and are not individually replaceable in standard service — the complete arm or sub-frame must be removed. Prolonged exposure to New Zealand road conditions, including salt spray and temperature cycling, degrades the rubber compound, causing the bonding layer to shear and the steel sleeve to move within the bush. The consequence is rear-axle toe and camber drift that produces rapid tyre wear on the inner edges and a distinct vagueness or directional instability at motorway speeds.

03Front and Rear Brake Caliper Guide Pin Seizure
Both the front and rear brake calipers use a sliding pin design where two hardened steel guide pins — coated in rubber boots and packed with high-temperature grease — allow the caliper body to float laterally as the pads wear. In New Zealand's environment, moisture tracks past degraded boots and corrodes the guide pin bores, causing the pins to seize in the caliper bracket. A seized pin prevents the caliper from retracting after brake application, leaving the outboard or inboard pad in constant contact with the rotor. This generates significant heat, accelerates pad and rotor wear asymmetrically, and in severe cases causes a brake fluid boil and partial loss of braking efficiency.

01AWD Transfer Case Front Coupling Actuator Failure
Can't confirm for this car
Can't confirm for this car
The Murano All-Wheel Drive system uses an electronically controlled viscous-electromagnetic coupling — housed at the rear of the transfer case — to distribute torque to the front axle on demand. The coupling is engaged by a rotary electromagnetic actuator whose field coils can fail from thermal cycling or moisture ingress, or whose position sensor can drift, causing the AWD-ECU to lose feedback and default to two-wheel-drive mode. In some failure modes the actuator attempts to engage and disengage repeatedly, producing a grinding noise and storing AWD system fault codes. Real-world consequence is loss of AWD traction in wet or loose conditions, which is the primary function of the system.

Does not apply
The rubber valve cover gaskets and spark plug tube seals on the VQ35DE degrade with age and heat cycling, allowing oil to seep from both cylinder head covers. The rear valve cover is particularly problematic because it sits beneath the intake plenum, making access extremely difficult and labour time substantially higher than for the front cover. When the spark plug tube seals fail, oil migrates into the spark plug recesses, saturating the ignition coils and causing cylinder-specific misfires. Both covers and the intake plenum gasket are typically replaced together as a set to avoid repeat disassembly. Oil dripping onto the exhaust manifold creates a persistent burning smell.

01EPS Rack Sensor Failure Causing Steering Warning
Does not apply
Does not apply
The Z52 Murano's electric power steering system incorporates a torque and angle sensor assembly integrated into the steering rack. Failure of this sensor triggers an EPS warning light and causes the power steering to default to a reduced-assist or no-assist mode, making the steering significantly heavier than normal. The fault is commonly caused by moisture ingress causing sensor corrosion, wiring connector degradation, or internal sensor element failure. In many cases the rack assembly requires complete replacement as the sensor is not sold separately.

02Power Steering System Failure Causing Loss of Steering Assist
Does not apply
Does not apply
The Z50 and Z51 Murano use a hydraulic rack-and-pinion power steering system. Multiple failure modes are documented in NHTSA complaints across both generations. The power steering pump can fail prematurely, causing a sudden and dramatic increase in steering effort. The high-pressure power steering hose is subject to chafing, fatigue cracking, and clamp failure, leading to fluid loss and assist reduction. Nissan issued recall 17V184 in 2017 covering 2013-2014 Z51 Muranos for a high-pressure hose clamp that could allow the hose to detach, creating both a loss of assist and a fire risk if fluid contacts hot exhaust components. The 2009 Z51 Murano accumulated 32 NHTSA steering complaints with documented instances of the steering wheel becoming suddenly heavy while driving.

03Air Conditioning Compressor Clutch Failure
Does not apply
Does not apply
The air conditioning compressor clutch on both Z50 and Z51 Muranos is a documented high-frequency failure. The clutch electromagnetic coil, clutch plate, and pulley bearing are subject to wear and heat damage. Clutch failure appears across multiple model years in NHTSA complaints and is a recurring topic on nissanmurano.org. The failure mechanism involves the clutch plate wearing or the electromagnetic coil losing sufficient magnetic draw to engage the clutch against the compressor pulley. Low refrigerant charge also prevents clutch engagement through the low-pressure protection switch, which can mask an underlying refrigerant leak as an apparent clutch fault. Once the clutch fails to engage, the air conditioning system produces no cooling regardless of system pressure.

04TPMS Sensor Battery Failure and Module Faults
Does not apply
Does not apply
The Z51 Murano uses wheel-mounted TPMS sensors with internal lithium batteries rated for approximately 7–10 years of service life. On 2008–2012 vehicles these sensors are now well past end-of-life and will trigger a persistent TPMS warning light as individual sensors go flat. Additionally, the TPMS control module fitted to early Z51 vehicles has a documented failure mode where it stops communicating with sensors and must be replaced separately from the sensors themselves.

05Power Window Regulator Cable and Clip Failure
Does not apply
Does not apply
The Z51 Murano uses a cable-type electric window regulator in all four doors. The plastic end-clips that attach the cable to the window glass carrier are prone to fracturing, causing the window to drop suddenly into the door cavity and become inoperative. This is a very widely reported failure on this generation of Nissan products; the driver's window is most commonly affected due to frequency of use but all four doors are susceptible.

01Electric Power Steering Rack Internal Rattle and Knock
Does not apply
Does not apply
The Z51 Murano replaced hydraulic assistance with a column-mounted electric power steering motor driving a conventional rack and pinion. The rack's internal anti-rattle spring and yoke mechanism — which maintains preload between the rack bar and pinion — loses its preload as the adjustment screw backs off from vibration over time. This allows the rack bar to knock against the housing under steering inputs, particularly when the wheel is moved on a stationary vehicle or over rough surfaces. In some units the EPS motor coupling also develops backlash, adding a secondary clunk felt directly at the steering wheel.

02Front Subframe Rubber Bush Wear and Compliance Steer (Z50/Z51)
Does not apply
Does not apply
The four front subframe mounting bushes on the Z50 and Z51 Murano deteriorate with age and mileage, allowing the subframe to shift under load. This produces vagueness in steering feel, mild pulling under braking and can promote uneven front tyre wear. NZ roads with potholes and rough surfaces accelerate bushing degradation. The fault is common by 120,000 km and is frequently overlooked at sale.

03Blocked sunroof drains flooding the cabin
Does not apply
Does not apply
The Murano's large sunroof relies on drain tubes that route water down the pillars; on both generations these block with debris and the water backs up into the headlining, footwells and under-carpet wiring instead of draining out. Owners find soaked carpets, a musty smell and, in bad cases, corroded floor connectors and electrical faults. It is cheap to prevent (clear the drains) but expensive once water has been sitting in the car.

Fluid leaks
01Intake manifold gasket deterioration (Z50)
Does not apply
Does not apply
The Z50 Murano's VQ35DE has a known weak point in the intake-manifold gaskets, which deteriorate and cause vacuum leaks - rough idle, hesitation and sometimes a coolant weep. It is a documented soft spot of this platform. Left alone a vacuum leak can throw the car into a lean-running fault; the fix itself is not huge but the manifold has to come off.
