Why Was This Recalled?

The fuel gauge, the component that reads and reports the battery parameters to the pump, could provide inaccurate readings, which present to the user in one of two ways: A) by triggering a Malfunction 4 Alarm, or B) by triggering a succession of notifications prior to the pump shutting off, including Alert 2 (Battery Low), Alert 3 (Battery Very Low) and Alarm 12 (Battery Very Low). The alarms in both scenarios notify the user that the pump has stopped delivering insulin.
