2012 Lincoln Navigator L

Certain vehicles equipped with a 6-speed automatic transmission may experience an intermittent loss of the Transmission Output-shaft Speed Sensor (OSS) signal to the Power Control Module.  This could potentially cause an unintended downshift into first gear, which depending on vehicle speed at the time of the downshift, may cause the rear tires to slide or lock up until the vehicle slows. This may result in a loss of vehicle control without warning, increasing the risk of a crash causing injury and/or damage to property. Correction: Dealers will reprogram the Powertrain Control Module with updated software.

Certain vehicles may have been equipped with an incorrectly manufactured Transmission Range Sensor.  In some instances, when the shift lever is placed in the "R" position, signal may not be provided to the electronic transmission range indicator "PRNDL" for "R" illumination and/or for backup lamp activation.  Should the backup lamps fail to illuminate, the driver's intentions to reverse may not be conveyed clearly to other motorists and/or pedestrians, which could result in property damage and/or personal injury.  Correction: Dealers will inspect and, if necessary, replace the Transmission Range Sensor.

On certain vehicles, the second row right-hand seat may have been manufactured incorrectly.  Improper weld penetration between the head restraint guide sleeve tube and the seat back frame could allow the headrest to fail during a rear-end vehicle crash, increasing the risk of injury to the seat occupant.  Correction: Dealers will inspect and, if necessary, replace the seat back frame for the second row right-hand seat.
