Overview
- The subpoenas, issued in March and April 2026, seek names, addresses and purchase histories for people who downloaded EZ Lynk’s Auto Agent app or bought its hardware, covering at least 100,000 users.
- The Justice Department says it wants the records to find and interview witnesses about how the tools were used and argues users gave up a privacy claim by agreeing to EZ Lynk’s terms.
- EZ Lynk calls the demand overbroad and says Apple and Google plan to challenge the subpoenas in court.
- The lawsuit, filed in 2021 under the Clean Air Act, accuses EZ Lynk of selling “defeat devices,” with prosecutors citing forum and Facebook posts showing emissions deletes, while the company says the app-and-OBD dongle system is used for diagnostics, tuning and updates; a judge rejected EZ Lynk’s Section 230 defense in August 2025.
- The scale dwarfs a 2019 order for a gun-scope app and could set a model for future cases that mine app store and retailer logs to identify large groups of users.
