A Conversation with Dexcom: Sensor Failures, Recalls & the Future of CGM

Dexcom is rolling out major updates, including a 15-day Dexcom G7 expected later this year, the recently released G7 app version 2.9 with AI-powered smart food logging, and a new integration between the Stelo CGM and Oura Ring that combines glucose with sleep, stress, and activity data.

But recent months haven’t been all smooth sailing. In March, Dexcom received an FDA warning letter for unvalidated material changes made to the G7. Though Dexcom says accuracy wasn’t affected, the incident highlights the strict oversight medical devices face. And recently, a Class I recall was issued for over 700,000 receivers due to rare but critical speaker failures that could cause alerts to go silent. Dexcom responded by offering free replacements and an online tool to check your device.

More troubling for everyday users has been a rise in G7 sensor issues—including “goosenecking,” where the sensor filament fails to insert properly, and connectivity failures that leave users without readings for days. Traveling without backups has only added to the stress. I shared my own experience—and what I’ve heard from others—in a recent podcast episode with two experts in the field.

After the episode aired and I heard from many of your experiences, it was time to go straight to the source—Dexcom. I sat down with Jake Leach, Dexcom’s President and COO, to unpack everything: the latest technology updates, regulatory challenges, how Dexcom tracks and addresses sensor issues, and what the future holds for CGM innovation.
