A well-documented failure on early Y51-platform Infiniti models is the electronic steering column lock (ESCL) malfunction, which can prevent the vehicle from recognizing the ignition sequence and leave the car unable to start. Owners report intermittent no-crank/no-start conditions that often become permanent as the steering lock module or related control logic fails.

This issue also affects: Infiniti QX50, Nissan Rogue

Common Symptoms

  • No-crank no-start condition
  • Ignition turns on but engine will not start
  • Steering lock warning or key system warning
  • Intermittent starting before complete failure

How to Fix

Diagnosis typically confirms power and Intelligent Key operation but no start authorization, often with steering lock-related faults stored. Repair usually involves replacing the steering lock assembly or performing the Infiniti service campaign/TSB procedure, then reprogramming as needed; dealer repairs commonly run about $900-$1,500, while some independent shops may be lower if programming capability is available.

Owner tips & cautions

  • TipIf the car intermittently fails to start, scan for BCM/steering lock faults before replacing the battery or starter; many owners misdiagnose this issue at first.
  • TipCheck whether the vehicle qualifies for any Infiniti campaign or prior warranty extension related to steering lock concerns before paying out of pocket.

Clogged or poorly routed sunroof drains can allow water to enter the cabin and soak wiring, connectors, and control modules under the dash or carpet. On the M37, owners commonly report water intrusion leading to erratic electrical behavior, battery drain, warning lights, and in severe cases damage to the BCM or related harnesses.

This issue also affects: Infiniti FX50, Infiniti QX50, Nissan Altima

Common Symptoms

  • Wet front carpet or damp interior
  • Random warning lights or electrical glitches
  • Battery drain after rain
  • Power accessories acting erratically
  • Musty odor inside cabin

How to Fix

Diagnosis involves water testing the sunroof drains, inspecting A-pillar and firewall drain routing, and checking for corrosion at connectors and modules. Repair may include clearing or rerouting drains, replacing damaged hose sections, drying the interior, and repairing corroded wiring or modules; minor drain service can be under $250, but BCM/harness damage can push repairs into the $1,200-$3,000 range.

Owner tips & cautions

  • TipClean the sunroof drains proactively and inspect the front footwells after heavy rain; catching moisture early can prevent module damage.
  • TipIf water intrusion is found, disconnect the battery and inspect under-carpet harnesses immediately because corrosion spreads quickly once connectors get wet.

The VQ37VHR engine can develop intermittent camshaft or crankshaft position sensor failures, causing hard starts, stalling, or reduced performance. Heat and age can degrade the sensors or their signal quality, and owners across Nissan/Infiniti VQ applications frequently report these failures as mileage increases.

This issue also affects: Infiniti FX45, Infiniti G35, Infiniti G37

Common Symptoms

  • Check engine light
  • Extended cranking or hard starting
  • Engine stalling intermittently
  • Reduced power or limp-like behavior

How to Fix

Diagnosis is done with a scan tool and live data to identify which sensor is dropping out, followed by checking connector condition and harness integrity. Repair involves replacing the failed camshaft or crankshaft position sensor with a quality OE-equivalent part and clearing codes; typical repair costs range from about $180-$450 depending on which sensor failed and labor access.

Owner tips & cautions

  • TipIf one sensor fails at higher mileage, inspect the others and the connectors at the same time since heat exposure affects them similarly.
  • TipAvoid cheap no-name sensors; many owners report repeat check-engine lights and drivability issues with low-cost replacements.

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 FX50, Infiniti M35

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.

The M37's weight and wheel/tire package contribute to wear in front suspension components such as tension rods, lower control arm bushings, and sway bar end links. Owners frequently report clunks, looseness, vibration under braking, and uneven tire wear as bushings crack or hydraulic-filled components deteriorate.

This issue also affects: Infiniti FX45, Infiniti FX50

Common Symptoms

  • Clunking over bumps
  • Steering shimmy or vibration
  • Uneven front tire wear
  • Wandering or loose front-end feel
  • Brake vibration not caused by rotors

How to Fix

A proper inspection checks for play in the front lower arms, compression/tension rods, ball joints, and sway bar links, followed by an alignment after repairs. Typical fixes include replacing worn control arms or tension rods in pairs; parts and labor usually total about $400-$1,200 depending on how many components are replaced and whether OEM or aftermarket parts are used.

Some M37 owners report the cabin blower motor becoming noisy, intermittent, or inoperative, sometimes tied to the blower motor itself and sometimes to the fan control module. As the blower ages, worn bearings or electrical faults can reduce airflow or cause the fan to work only at certain speeds.

Common Symptoms

  • Weak or no airflow from vents
  • Blower works intermittently
  • Squealing or chirping from dash area
  • Fan only works on certain speeds

How to Fix

Diagnosis includes checking blower power and ground, command signals from the HVAC control head, and current draw of the blower motor. Repair usually involves replacing the blower motor and, if needed, the blower control module/resistor equivalent; total cost is commonly about $250-$700 depending on parts source and labor time.
