FreeStyle Libre 3 Plus and iLet Lawsuit, Shannon Johnson Sues Abbott and Beta Bionics Over Husband’s Death

A Kentucky woman has sued Abbott Laboratories, Abbott Diabetes Care and Beta Bionics, alleging that a FreeStyle Libre 3 Plus glucose sensor and a Beta Bionics iLet ACE Pump caused her husband’s death.

Shannon Johnson, individually and as administratrix of the estate of Bennie Johnson, filed the lawsuit on October 1, 2026, in the U.S. District Court for the Eastern District of Kentucky. The case number is 6:26-cv-00270, and it is assigned to Judge Karen K. Caldwell. The docket lists it as a personal-injury product-liability case, and the plaintiff has demanded a jury.

This is not a class action, and there is no settlement or claim form. The claims are allegations. No court has found that either device caused Bennie Johnson’s death.

What Does the Shannon Johnson Complaint Allege About the FreeStyle Libre 3 Plus and iLet Pump?

The docket confirms the filing but not the complaint text, so the details below come from reports describing the complaint. They are allegations only.

According to those reports, Bennie Johnson used a FreeStyle Libre 3 Plus continuous glucose monitor wirelessly paired with a Beta Bionics iLet ACE Pump. The complaint alleges that on the evening of October 8, 2025, the sensor reported an extremely high glucose reading of about 400, and that the paired pump then delivered insulin at around 8 p.m. and again around midnight. It alleges the readings were inaccurate, the doses were inappropriate, and the resulting severe hypoglycemia caused him to lose consciousness and die.

What Does the Lawsuit Allege Against Abbott and Beta Bionics?

• Abbott Laboratories and Abbott Diabetes Care: that the FreeStyle Libre 3 Plus failed to measure glucose accurately and that Abbott knew or should have known of the risk of inaccurate readings but kept marketing the product as accurate and reliable.
• Beta Bionics: that the iLet pump did not adequately evaluate, limit, suspend or warn against insulin delivery based on unreliable sensor data, and that the two devices did not operate safely together as a paired system.

The plaintiff seeks damages for wrongful death, personal injury, loss of consortium and related relief. The defendants will have the chance to respond and raise their own defenses.

What Does the FDA Say About FreeStyle Libre 3 and Libre 3 Plus Sensors?

On November 24, 2025, Abbott announced a medical-device correction for certain FreeStyle Libre 3 and Libre 3 Plus sensors in the U.S. The FDA posted the company’s announcement on its website. The announcement says internal testing found that some sensors may provide incorrect low glucose readings, that the issue traced to one production line, and that it involved about 3 million U.S. sensors from that line, roughly half of which were estimated to be expired or used. Abbott reported worldwide 736 severe adverse events (57 in the U.S.) and seven deaths (none in the U.S.) potentially associated with the issue.

Two points matter for readers:

• The correction concerned low readings. The Johnson complaint alleges a high reading. The correction does not describe the problem alleged in this lawsuit.
• The alleged events (October 8, 2025) came before the November 2025 announcement.

The correction does not show that any device caused Bennie Johnson’s death.

Is the FreeStyle Libre 3 Plus and iLet Lawsuit a Class Action?

No. The docket lists Shannon Johnson as plaintiff and administratrix and does not identify a proposed class. You are not part of this lawsuit because you use a Libre 3 Plus or an iLet pump, and there is no registration, claim form, administrator or deadline. For how real class settlement claims work, see How To Claim A Lawsuit Settlement?

What Should FreeStyle Libre 3 Plus and iLet Users Do Now?

Nothing needs to be filed. Medically, Abbott’s announcement tells people to use a blood glucose meter to make treatment decisions when sensor readings do not match symptoms or expectations, and to check at FreeStyleCheck.com whether a sensor is affected by the correction. Do not change insulin dosing without talking to your doctor.

If you believe a device caused you or a family member a serious injury, keep:

1. Device details: model, serial and lot numbers, and the pump information
2. Glucose readings, including CGM history and meter readings
3. Insulin and pump records
4. Medical and hospital records
5. Messages with Abbott or Beta Bionics, and support tickets
6. The devices and packaging, if you still have them

Filing deadlines vary by state, so consider speaking to a licensed attorney promptly. For background on this kind of case, see What Is a Wrongful Death Lawsuit? Everything Families Need to Know.

What Happens Next in the Johnson Lawsuit Against Abbott and Beta Bionics?

The case is at its earliest stage. The docket shows the complaint, a notice of filing and a notice of deficiency about the summons. Next steps typically include service on the defendants, their responses or motions to dismiss, discovery, possible summary-judgment motions, and then trial or settlement. Nothing on the docket establishes liability.

How Is This Different From Other Abbott Lawsuits?

Other Abbott device lawsuits involve different products and claims. For example, see Abbott Spinal Cord Stimulator Lawsuit Filed Were You Affected. A case about one Abbott device does not affect users of another.
