Recall Details

Company:
Dexcom, Inc.
Reason for Recall:
The affected devices are the Dexcom G7 Continuous Glucose Monitoring System (CGM System) using iOS, watchOS and Android App software (versions 2.8.0 or earlier) and Dexcom ONE+ CGM System using iOS and Android App software (versions 1.4.0 or earlier), henceforth referred to as the App. The affected App does not provide an expected "Sensor Failed" alert when the transmitter sends a "transmitterFailed" error message to the App when the CGM experiences a hardware or firmware failure. Instead, the App ends the CGM sensor session, stops reporting glucose values and displays the Start Sensor screen or No active sensor message without alerting the user, which can lead to missed detection of a hyperglycemic or hypoglycemic event and a delay in treatment.
Classification:
Class I - Dangerous

Dangerous or defective products that predictably could cause serious health problems or death.

Status:
ongoing

A software defect in which a low-priority file I/O check blocks the higher-priority thread responsible for processing estimated glucose values (EGVs) and trend arrows. When the app is running in the background, EGV notifications may queue up and then "replay" sequentially when the user brings the app to the foreground, causing the Glucose Compass to flicker through previous EGVs. In more severe instances, the app may perceive signal loss and deploy signal loss mitigations. This delay in EGV and alert processing creates a risk that users may miss detection of a hypoglycemic or hyperglycemic event, or make treatment decisions based on outdated glucose information.

A software defect in version v1.15.0 of the G6 Android app can cause the app to terminate unexpectedly, which may result in the user not receiving estimated glucose values, alarms, alerts or notifications. This could result in the missed detection of a hyperglycemic or hypoglycemic event, protentional resulting in severe hyperglycemia, diabetic ketoacidosis (DKA), or hyperosmolar hyperglycemic state (HHS).
