Dexcom G7Recalls & reported problems across all models

We found 32 models of Dexcom G7 by Dexcom, Inc. in the FDA's device registry (GUDID). Together they are named in 325,909 adverse event reports in the FDA's MAUDE database, received between Dec 27, 2022 and Sep 30, 2026 — classified as 9 deaths, 4,307 injuries, 321,576 malfunctions.

The most frequently reported specific device problem is “Wireless Communication Problem” (93,013 reports).

8 FDA recall records name at least one of these models by its device identifier, 8 still open.

Reports come from manufacturers, hospitals and patients and are not verified by the FDA. A report does not prove the device caused the event. Widely used products collect more reports, so totals can't be used to compare products or estimate failure rates. Only reports that name a model's exact device identifier are counted.

Dexcom G7 recalls

FDA recall records that name at least one of these models by its device identifier, newest first. Each recall usually covers specific models or lots, so check the details.

   Certain lots of Dexcom G7 sensors originally designated as scrap and intended for destruction were stolen during the destruction process. The sensors were later sold to pharmacies and distributors by Pharmsource, LLC. Lot 1725204004 were designated for destruction because the G7 sensors were not properly sterilized and have an increased risk of skin infection if used. Lot 1725069002 were designated for destruction due to an increased risk of having no sensor readings available or experiencing sensor inaccuracy that includes the potential for missed detection of a hyperglycemic event or incorrect treatment decisions that can result in patient injury, including medical intervention to prevent permanent injury or impairment. Additionally, due to the unknown storage and handling and storage conditions these sensors may have undergone during the distribution, these sensors may present additional risk.

   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.

   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.

   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.

   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.
