Tandem t:slim X2 and Mobi Insulin Pumps Recalled for Software Dosing Error

Sign in to monitor this recall

Summary

Tandem Diabetes Care is recalling 148 insulin pumps, specifically the t:slim X2 and Tandem Mobi models running software version 7.9. A software defect can cause the pumps to deliver the wrong amount of insulin if they lose connection with a glucose sensor while blood sugar levels are high. Affected units were distributed across 29 U.S. states including California, Texas, and New York between February and April 2025. No injuries have been reported, but consumers should contact the manufacturer to arrange for a software correction.

Risk

The software incorrectly calculates glucose trends after a data gap, which can cause the pump to deliver too much or too little insulin. This dosing error can lead to severe hypoglycemia (dangerously low blood sugar) or hyperglycemia (dangerously high blood sugar), both of which can cause serious medical complications or death.

What You Should Do

  1. This recall affects Tandem t:slim X2 and Tandem Mobi Insulin Pumps equipped with Control-IQ technology and software version 7.9.
  2. Identify your device by checking for UDI codes 00389152407012 (t:slim X2) or 00389152480114 (Mobi) and verify if the software is Version 7.9.
  3. Stop using the recalled insulin pump immediately and switch to an alternative insulin delivery method as directed by your healthcare provider.
  4. Contact Tandem Diabetes Care or your distributor to arrange for a software correction, replacement, or further instructions regarding the software update.
  5. If you have experienced health concerns related to insulin dosing while using these devices, contact your healthcare provider immediately.
