The Dexcom lawsuit most people are searching for is a consumer class action by G6 and G7 users who say they overpaid for glucose monitors that, they allege, were less accurate and less reliable than advertised. Five federal cases became one in San Diego on May 15, 2026. There is no Dexcom settlement, no fund and no claim form. Two separate investor lawsuits are also pending.

What the Lawsuits Say Happened
In March 2025 the FDA sent Dexcom a warning letter after inspecting its plants in San Diego and Mesa, Arizona. The first consumer complaint, Levens v. Dexcom, filed September 29, 2025, builds on that letter: it alleges Dexcom changed a material in its G6 and G7 sensors without new FDA clearance and that readings became more variable as a result.
Across six complaints, the plaintiffs allege they overpaid for G6 and G7 devices and components because the products were “adulterated or misbranded” under federal law, did not perform as advertised, and were marketed with misleading claims about accuracy and reliability. One complaint, brought by a parent of a child with Type 1 diabetes, alleges sensors never lasted their advertised 10-day wear period. The suits also point to two 2025 recalls — receivers whose speakers could fail to sound low- and high-glucose alarms, and a G7 app error that could end a sensor session without a “Sensor Failed” alert. Dexcom says it will defend the claims vigorously; none of the allegations has been proven.
Case Details
Consumer case (federal): In re: Dexcom CGM Litigation, No. 3:25-cv-02565-BJC-JAC, U.S. District Court for the Southern District of California, consolidated May 15, 2026 from Levens, Estravit, Dalora, Grisoli and Dickinson.
Consumer case (state): Chatelain v. Dexcom, Inc., No. 25STCV30722, Los Angeles County Superior Court — stayed while the federal case proceeds.
Investor cases (shareholders only): Prime v. Dexcom, Inc., No. 1:25-cv-08912 (S.D.N.Y.), filed October 27, 2025, over statements about G7 accuracy and reliability; and In re Dexcom, Inc. Class Action Securities Litigation, No. 24-cv-1485-RSH-VET (S.D. Cal., Judge Robert S. Huie), over 2024 revenue guidance. Related shareholder derivative suits are stayed.
Status: Consolidated, Pretrial, No Settlement
The investor cases are further along but still unresolved: in the New York case, Dexcom moved to dismiss on June 9, 2026; in the San Diego securities case, a motion to dismiss the second amended complaint was filed February 20, 2026, with no oral argument scheduled as of that report.

Who Is in the Proposed Classes
The consumer plaintiffs seek nationwide classes and state-specific subclasses of people who bought Dexcom G6 or G7 devices or components. The exact class definitions will be set in the amended consolidated complaint and, later, by the court — they do not exist in final form yet.
You do not need to sign up. If a class is certified or a settlement is reached, a court-appointed administrator notifies class members directly. Keep pharmacy or supplier receipts, insurance statements and records of sensor replacements; they show what you paid and when.
Investors are a separate group. The New York securities case covers people who bought Dexcom common stock between January 8, 2024 and September 17, 2025, according to lead counsel. Buying a sensor does not make you part of it.
What a Dexcom Settlement Could Pay
People who say a missed alert or bad reading caused a hospitalization or other injury are in a different position. Those are individual personal-injury claims, not part of the consumer class; at least one plaintiffs’ firm has said it is evaluating such claims. Our medical device lawsuit calculator explains how those claims are generally valued.
How cases like this one end
Our copy of the federal courts’ own case database covers 80,165 other statutory actions casesclosed in U.S. federal district courts between 2015 and 2025, 11.8% of them filed as class actions:
- 26% ended in a settlement recorded by the court. Another 22.4% were dismissed voluntarily, which often follows a private settlement — so the real settlement share sits between 26% and 48.4%.
- 7.4% were decided on a motion before any trial.
- 1 in 155 reached a trial (0.6%), after a median of 22 months.
- Median time from filing to the end of the case: 5 months.
- Only 1,717 of them (2.1%) record a money award at all; the median of those is $195,000.
These are base rates for this type of case (federal other statutory actions cases) — not a prediction about this lawsuit, and not legal advice. Source: Federal Judicial Center, Integrated Database (civil), analysed by Settlement Insight. Cases heard in state courts are not included.

Three Things to Watch For
Recalls plus pending lawsuits plus a medical device people depend on daily is a combination imposters exploit:
“Claim your Dexcom settlement” pages
There is no Dexcom settlement, so there is no claims portal. A site asking for your insurance ID, Dexcom account login or Social Security number to “reserve your payment” is collecting data, not filing a claim.
Fake recall replacement messages
The real receiver recall runs through dexcom.com/checkreceiver and Dexcom Technical Support at 1-844-478-1600, and replacements are free. A text or call asking you to pay shipping or a fee for a “recall replacement” is not from Dexcom.
Shareholder “deadline” ads aimed at patients
Law-firm ads about Dexcom “class action deadlines” usually refer to the investor cases, where the deadline was to apply as lead plaintiff. They do not create a payout deadline for sensor users, and investors stay in a securities class without signing anything.
Dexcom Lawsuit — Questions People Actually Ask
Is there a Dexcom settlement I can file a claim for?
No. As of October 5, 2026 we found no settlement in the consumer or investor cases. There is no fund, administrator, claim form or deadline. If that changes, class members are notified by a court-appointed administrator.
What is the Dexcom lawsuit about?
G6 and G7 users allege they overpaid because the devices were adulterated or misbranded under federal law, did not perform as advertised, and were marketed with misleading accuracy and reliability claims. The suits cite a March 2025 FDA warning letter and two 2025 recalls. Dexcom says it intends to defend the claims vigorously.
Am I part of the Dexcom class action?
If you bought Dexcom G6 or G7 devices or components, you may fall within the proposed classes. The final definitions are not set and no class has been certified. You do not need to join anything now.
My Dexcom missed a low or high alarm and I was hurt. Is that this case?
Not directly. The class actions seek economic losses such as overpayment. Injuries are handled as individual personal-injury claims with their own filing deadlines, which vary by state — a licensed attorney can tell you which applies. Keep the device, sensor lot information and medical records, and consider reporting the event to the FDA through MedWatch.
Is my Dexcom receiver or app recalled?
Check the FDA receiver recall notice and dexcom.com/checkreceiver; affected receivers are replaced free through Dexcom Technical Support. For the G7 app correction, updating to a current app version was mandatory after August 20, 2025.
I own Dexcom stock. Which case is mine?
Investors have two separate securities cases: Prime v. Dexcom in New York over G7 statements, and the San Diego case over 2024 revenue statements. Both face motions to dismiss and neither has settled. Lead plaintiffs are already appointed; other investors remain class members unless they opt out of a certified class.
Where is the Dexcom lawsuit being heard?
The consumer case is In re: Dexcom CGM Litigation, No. 3:25-cv-02565-BJC-JAC, in the U.S. District Court for the Southern District of California. A parallel state case in Los Angeles County Superior Court is stayed.
What happens next, and how long will it take?
As of Dexcom’s latest quarterly report, the court had yet to choose interim class counsel. Then plaintiffs file an amended consolidated complaint and Dexcom responds, likely with a motion to dismiss. Class certification, any settlement and any payment would come after that; there is no date-certain schedule. Meanwhile, see open class action settlements for claims you can file today.
Separate from this case: were you injured in the last 2 years?
Class-action payouts are fixed amounts through an administrator. A personal injury claim is a different case — and often worth far more. Free estimate, no obligation.
