  • openFDA Device Enforcement Report-date coverage June 20, 2012–July 08, 2026 Known gap: openFDA describes 2004-present coverage, but the current export has no report-date records in this interval.
  • openFDA Device Recall event_date_initiated coverage June 01, 1997–June 30, 2026

Enforcement coverage uses report dates; product initiation dates can precede those bounds. Device-enrichment coverage uses FDA event_date_initiated.

Reason for recall

A software defect in Version 7.9 of the pump software for Tandem t:slim X2 and Tandem Mobi pumps, when used with Control IQ+ technology, will cause the pump to incorrectly interpolate glucose trends when the Estimated Glucose Value (EGV) is above 255 mg/dL at the start or end of a gap in data collection due to a lapse in connection from a paired continuous glucose monitor (CGM) sensor, which can lead to under-delivery or over-delivery of insulin based on inaccurate result leading to severe cases of hypoglycemia or hyperglycemia.
