2009 Nissan Murano

On certain vehicles, the brake Hydraulic Control Unit (HCU) may become contaminated by a reaction between brake fluid and internal anti-corrosion coatings. This could cause an internal control valve to stick open, potentially increasing brake pedal travel and/or stopping distances. This may create an increased risk of a crash causing injury and/or damage to property. Correction: Dealers will flush the brake system with DOT 4 brake fluid. The HCU will then be tested to detect a possible stuck valve condition. If necessary, HCU will be replaced.

On certain vehicles, the filament in the bulb of the Daytime Running Lamps (DRL) may burn out due to a shorter lifespan than expected.  A loss of DRL illumination could render the vehicle less visible to other motorists and to pedestrians during daylight hours, possibly resulting in a crash causing property damage and/or personal injury.  Correction: Dealers will replace the Daytime Running Lamp bulbs with a longer life type bulb.

On certain vehicles, material in the nut used to secure the sensor-transmitter of the Tire Pressure Monitoring System (TPMS) may corrode and crack in areas with heavy concentrations of road salt.  If this occurs, the nut may come out of the TPMS sensor-transmitter causing a rapid loss of tire air pressure.  This could adversely affect vehicle control and cause a crash resulting in property damage, personal injury or death.  Correction: Dealers will replace the TPMS nut with a revised version.

On certain vehicles, a varistor in the Occupant Classification System (OCS) control unit located in the passenger seat cushion may have been manufactured incorrectly.  Under certain conditions, this could cause an interruption of signal between the OCS and the Airbag control unit (ACU). This could result in the passenger airbag being suppressed. The (red) supplemental airbag warning light would flash & the (amber) front passenger airbag status light would illuminate to alert the vehicle operator, however in case of a crash a suppressed airbag could result in personal injury or death.   Correction: Dealers will test the signal between the OCS & ACU and if necessary will replace the seat cushion containing OCS hardware.

If the vehicle battery becomes significantly discharged and the voltage in the electrical system drops (because, for example, the ignition is left in the "ON" position for a significant length of time without the engine running), the Airbag Control unit (ACU) is designed to suppress the passenger airbag and illuminate the passenger airbag status light.  When the battery recharges and correct voltage is restored, the ACU is designed to reactivate the passenger airbag system.  On certain vehicles, incorrect software programming may not allow the ACU to reactivate the airbag as intended.  This can result in the passenger airbag being suppressed without lighting the warning indicator and the airbag status light.  Failure of the airbag to inflate during a crash could increase the passenger seat occupant's risk of injury.  Correction: Dealers will reprogram the ACU.
