Diabetes patients across the United States trusted Dexcom’s G6 and G7 Continuous Glucose Monitoring (CGM) systems to alert them when their blood sugar reached dangerous levels. Instead, many discovered that these devices failed at the most critical moments, leaving them vulnerable to severe health emergencies, hospitalizations, and in some tragic cases, death.
The Dexcom lawsuit alleges that defective sensors failed to warn users of dangerous blood sugar levels, leading to preventable medical crises. For individuals living with diabetes, these devices represent more than convenience—they are essential safety tools that can mean the difference between life and death. When they fail, the consequences can be devastating.
A class action Dexcom lawsuit was filed in September 2025 against the manufacturer, highlighting widespread issues with both G6 and G7 systems.
The legal action reveals a pattern of device failures that have put countless patients at risk, raising serious questions about the safety and reliability of these widely-used medical devices.
The most serious defect identified in Dexcom G6 and G7 systems involves the complete failure of the alert system to notify users of dangerously high or low blood sugar levels.
Medical research has demonstrated that failures in CGM alerts can lead to prolonged hypoglycemic events, which can result in seizures, coma, or death, particularly for patients who cannot feel hypoglycemic symptoms.
Many patients have reported that their devices simply stopped working when they needed them most. The importance of functioning alerts cannot be overstated—research indicates that functioning alerts can reduce the time spent in dangerous glycemic ranges, highlighting the critical nature of these alerts for patient safety.
Recent litigation has revealed that Dexcom G6 and G7 devices were allegedly manufactured with unapproved materials, rendering them adulterated and misbranded under federal law. These manufacturing defects have contributed to the devices’ failure to perform as advertised, with users experiencing inaccurate glucose readings that fail to reflect actual blood sugar levels and missed critical alerts for dangerous blood glucose levels.
The Dexcom sensor defects have led to serious health emergencies and hospitalizations, affecting patients who relied on these devices for their daily diabetes management. FDA inspections have identified significant issues with sensor variability and accuracy, raising questions about the consistency and reliability of Dexcom’s manufacturing processes.
The FDA issued a Class I Dexcom recall due to critical alert system failures—the most serious type of recall, indicating a reasonable probability that the use of the product will cause serious adverse health consequences or death. The fact that both Dexcom G6 and G7 systems have received this classification underscores the severity of the safety concerns.
The Dexcom recall affects both G6 and G7 continuous glucose monitoring systems, with the 2019 Class I recall for certain Dexcom G6 receivers specifically addressing alarm failures that could prevent users from being notified of critical glucose levels. Subsequent recalls have addressed similar issues with the G7 system, indicating that Dexcom has not adequately resolved these fundamental safety problems across product generations.
The Dexcom FDA warning letter cited unauthorized modifications to sensor components, suggesting that the company may have made changes to device components without proper regulatory approval or notification. According to the Dexcom FDA warning letter, the company altered critical parts without approval, leading to devices with higher variability and lower accuracy than FDA-approved versions.

The recent Dexcom FDA warning addresses manufacturing defects and safety concerns that have contributed to the widespread device failures. The Dexcom FDA warning highlights the risks of using devices with unapproved materials, which may explain why so many patients have experienced life-threatening situations when their devices failed to function properly.
Patients using Dexcom G6 and G7 systems have experienced a range of serious health consequences when the devices fail to alert them to dangerous blood sugar levels. At least 56 severe adverse events have been documented, including seizures and loss of consciousness.
The documented health emergencies include seizures resulting from prolonged low blood sugar, loss of consciousness and coma, hospitalization for severe hypoglycemic episodes, and permanent neurological damage from extended periods of dangerously low glucose levels. Additionally, patients have suffered from diabetic ketoacidosis from undetected high blood sugar and severe hyperglycemic events requiring emergency medical intervention.
The consequences of device failures are particularly severe for patients who cannot feel hypoglycemic symptoms—a condition known as hypoglycemia unawareness. For these individuals, the CGM alert system is their only warning of dangerous blood sugar levels, making device reliability literally a matter of life and death.
Patients have also experienced severe skin reactions or infections at the sensor application site, wrongful deaths linked to device failures, and permanent injuries resulting from delayed treatment of glucose emergencies.
Individuals affected by device failures may be eligible to join the Dexcom lawsuit based on specific criteria. The class action lawsuit filed in September 2025 includes all U.S. residents who purchased Dexcom G6 or G7 devices within the applicable statute of limitations.
Purchase Timeline Requirements: Individuals must have purchased a Dexcom G6 or G7 monitor or sensor between January and November 2024. This specific timeframe is critical for class action eligibility.
Qualifying Circumstances: You may qualify for the lawsuit if you or a family member purchased Dexcom G6 or G7 devices during the specified timeframe, suffered harm from using these devices including missed critical alerts or inaccurate readings, or experienced serious skin reactions that resulted in diabetic emergencies or other life-threatening complications. Use this Dexcom Claim Form.
Importantly, even if you did not suffer physical injuries but purchased a Dexcom G7 device during the specified timeframe (January-November 2024), you may still have grounds to file a lawsuit based on the misleading marketing practices of Dexcom.
Beyond the class action, the Dexcom G7 lawsuit includes claims for individuals who have experienced serious health complications and may qualify for personal injury lawsuits with potentially higher compensation.
To have a valid claim, individuals must have been prescribed the Dexcom G6 or G7 device, used the device as prescribed, experienced a significant health emergency related to the device’s failure, and have medical evidence linking their health issues to the device failure.
Qualifying Health Complications include:
Lawsuits against Dexcom are based on several legal theories including design defects in the alert system and sensor technology, manufacturing flaws including use of unapproved materials, inadequate testing before market release, and failure to warn about the risks of inaccurate glucose readings.
Victims of Dexcom device failures may be entitled to compensation claims from any potential settlements that may occur for medical expenses (past and future costs of treatment), lost wages and earning capacity, pain and suffering, loss of quality of life, and emotional distress.
