This bulletin applies to 2019 Subaru Forester vehicles. There have been several cases involving damaged or deformed battery sensors. These reports usually describe a loose negative battery terminal (battery sensor) and/or cable connections.
As a reminder, unless the battery or the battery sensor is being replaced, the sensor should NOT be removed from the negative battery post. When disconnecting the negative battery cable, it should be removed from the battery sensor, NOT the sensor assembly from the battery post.
When removing or installing the negative battery cable from or to the battery sensor, always support it and hold it in place with one hand while loosening or torquing either retaining nut. Doing so will prevent battery sensor damage/deformation from unnecessary movement.
Note that the torque specification for the battery sensor retaining nut has been changed from 4.4 ft-lb to 2.9 ft-lb. The torque specification for the negative battery cable retaining nut is unchanged at 5.5 ft-lb. Never over-torque either nut.
