On the 2009-2013 Infiniti FX50, as these vehicles age, cooling system issues such as radiator seepage, fan control problems, or thermostat degradation can lead to elevated engine temperatures. The VK50VE V8 runs hot under load, so any reduction in cooling efficiency can quickly cause overheating, especially in traffic or hot climates.

This issue also affects: Infiniti FX45, Infiniti M56, Nissan Altima

Common Symptoms

  • Temperature gauge rising in traffic
  • Coolant smell near front of vehicle
  • Visible coolant loss
  • Cooling fans not running properly
  • Engine overheating warning

How to Fix

Diagnosis should include pressure-testing the cooling system, checking for radiator tank leaks, verifying fan operation, and monitoring live coolant temperature data. Repairs may involve replacing the radiator, thermostat, hoses, or fan assembly and refilling with the correct coolant; total cost typically ranges from $300 to $1,400 depending on the failed component.

On the 2009-2013 Infiniti FX50, clogged or poorly routed sunroof drains can allow water to enter the cabin, often soaking carpet, wiring connectors, and body control electronics. On the FX platform, owners commonly report water intrusion leading to electrical malfunctions, musty interior odor, and intermittent warning lights after heavy rain or car washes.

This issue also affects: Infiniti M37, Infiniti QX50, Nissan Altima

Common Symptoms

  • Wet front or rear floorboards
  • Musty smell inside cabin
  • Random electrical glitches
  • Warning lights after rain
  • Power accessories acting erratically

How to Fix

Diagnosis involves water testing the sunroof cassette drains, inspecting A-pillar and firewall drain routing, and checking under-carpet harnesses/modules for corrosion. Repair usually includes clearing or rerouting drains, replacing damaged connectors or modules, drying the interior thoroughly, and sometimes replacing the BCM or affected harness sections; costs range from about $150 for drain service to $1,500+ if electronics are damaged.

Owner tips & cautions

  • TipOwners recommend checking and cleaning the sunroof drains yearly, especially if the vehicle is parked under trees.
  • TipIf the carpet gets wet, pull trim and dry the padding quickly; leaving it soaked often leads to connector corrosion and recurring electrical faults.

On the 2009-2013 Infiniti FX50, a known Nissan/Infiniti issue on this era is failure of the electronic steering lock (ESCL/steering lock control unit), which can prevent the vehicle from recognizing the ignition sequence and leave the FX50 in a no-start condition. Owners report the problem as an intermittent or sudden failure tied to the steering lock assembly and Intelligent Key start authorization system.

This issue also affects: Infiniti QX50, Nissan Rogue

Common Symptoms

  • Push-button start does nothing
  • Steering remains locked
  • Intermittent no-start with key recognized
  • Security/Intelligent Key warning messages
  • Vehicle stuck in ACC or LOCK mode

How to Fix

Diagnosis typically includes checking for power at the steering lock unit, confirming Intelligent Key operation, and scanning BCM/IPDM-related faults. Repair usually involves replacing or bypassing the steering lock module depending on campaign/repair status, then performing key/immobilizer relearn if needed; typical repair cost is about $400-$1,200 depending on dealer programming and parts.

On the 2009-2013 Infiniti FX50, infiniti service bulletin ITB00-024I applies to all Infiniti vehicles and defines brake judder as vibration felt through the vehicle, steering wheel or brake pedal while braking. The bulletin identifies rotor thickness variation and/or rotor runout as the cause; brake-pedal pulsation and, in severe cases, steering-wheel oscillation can result.

This issue also affects: Infiniti FX35, Infiniti M37

Common Symptoms

  • Vehicle vibration while braking
  • Brake-pedal pulsation
  • Steering-wheel oscillation while braking

How to Fix

Verify the condition with the driver and a road test. Infiniti directs technicians to correct brake judder by machining the rotors with an approved on-car brake lathe. If a rotor is replaced, index it to the axle hub for minimum runout, tighten lug nuts evenly with a torque wrench, and burnish serviced brakes as specified in ITB00-024I.

On the 2009-2013 Infiniti FX50, the FX50's weight, large wheels, and performance-oriented suspension contribute to wear in front control arm bushings, ball joints, and sway bar end links. Owners frequently report clunks over bumps, uneven tire wear, and looseness in the front end as mileage climbs.

This issue also affects: Infiniti FX45, Infiniti M37

Common Symptoms

  • Clunking over bumps
  • Uneven front tire wear
  • Loose or wandering steering feel
  • Front-end vibration
  • Noise during low-speed turns

How to Fix

Inspection should include checking upper and lower control arm bushings, ball joint play, sway bar links, and alignment angles. Repair commonly involves replacing worn control arms or links as complete assemblies, followed by a four-wheel alignment; typical cost is around $400-$1,500 depending on how many components are replaced.

On the 2009-2013 Infiniti FX50, owners occasionally report check-engine lights caused by EVAP system leaks, often related to the gas cap, purge control valve, vent valve, or associated hoses. These faults usually do not affect drivability much, but they can prevent emissions readiness and trigger recurring warning lights.

This issue also affects: Infiniti FX35, Infiniti G35, Nissan Rogue

Common Symptoms

  • Check engine light on
  • Loose or worn gas cap
  • Failed emissions inspection
  • Occasional fuel vapor smell
  • No major drivability change

How to Fix

Diagnosis starts with reading EVAP-related codes, inspecting the fuel cap seal, and smoke-testing the EVAP system for leaks. Repairs may be as simple as replacing the gas cap or may require a purge/vent solenoid and hose replacement; typical cost runs from about $40 to $450 depending on the fault.
