Class I: Dangerous 08/28/2025 device

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).
Class I: Dangerous 07/24/2025 device

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.

Class I: Dangerous 05/12/2025 device

Defective foam or an assembly error may cause the receiver speaker to lose contact with the printed circuit board, leading to missed audible alerts for low or high blood glucose values. A missed audible alert for low or high blood glucose values could lead to untreated hypo or hyperglycemia which can cause seizures, vomiting, loss of consciousness, or death.

Class II: Risk 05/05/2025 device

A bug in the 2.7.0 version of the G7 iOS App can cause the app to enter a state where it stops updating the estimated glucose value (EGV) and continues to show this stale EGV. If the user is unaware that the EGVs are not being updated and that glucose alerts will not trigger, there is potential for the missed detection of a hyperglycemic or hypoglycemic event or a treatment decision made based off incorrect data. There is no impact to transmitter communication with concurrently connected displays. A concurrently connected receiver, Apple Watch, and/or insulin pump will continue to receive EGVs directly from the transmitter when the app is in the problematic state. There is no impact to Automated Insulin Dosing (AID) therapy as the AID system continues to receive EGVs directly from the transmitter.
Class II: Risk 01/27/2025 device

Under very rare situations, the Dexcom G6 touchscreen receiver may not provide high or low glucose alarms/alerts as designed, which can result in two different conditions. First, if a receiver operating system .net error occurs when an alarm/alert should be triggered, the initial alarm/alert will not be delivered until a subsequent alarm/alert is triggered. At that time, the initial alarm/alert is delivered, but not the second one. Alarm/alerts will continue to be delayed and be one alarm/alert behind, causing delayed alarm/alerts until the receiver is reset. This condition could result in the missed detection of a hyperglycemic or hypoglycemic event. Second, a single EGV reading may be delayed for 5 minutes after the initial .net operating system error. If the user receives a single EGV reading delayed by 5 minutes, the delay is not expected to cause user harm.
