Early Warning Reporting (EWR)

What It Means

Early Warning Reporting (EWR) is a quarterly data submission program established by the TREAD Act of 2000 (Public Law 106-414) and codified at 49 CFR Part 579. EWR was created in direct response to the Ford Explorer/Firestone tire tread separation scandal, during which both companies possessed internal warranty and incident data that would have revealed the emerging defect years before the 2000 recall, but NHTSA had no mechanism to compel that information. Under EWR, every manufacturer that produces more than 5,000 vehicles per year in the U.S. market must submit quarterly reports containing: aggregate production numbers, warranty claims broken down by component category, field reports from dealers, consumer complaints received directly by the manufacturer, property damage claims, and itemized death and injury claims including incident dates and narrative descriptions. Smaller manufacturers submit less detailed "light" EWR reports. The data is submitted in structured CSV format and ingested into NHTSA's Artemis database, where ODI statisticians run anomaly detection against peer vehicles and historical baselines. EWR data led directly to investigations that produced the 2009-2014 GM ignition switch recall, the 2015-2019 Hyundai/Kia engine-fire recalls, and multiple Tesla Autopilot investigations. Much of EWR data is confidential under 49 U.S.C. 30166(m), but death and injury incident summaries, production totals, and certain aggregate counts are publicly released. Manufacturers face civil penalties of up to $27,168 per day for late or incomplete EWR filings. RecallCheck does not currently display EWR data directly (it is confidential for warranty and field-report components), but several of the largest recalls on site were opened as a direct result of NHTSA EWR pattern analysis, so EWR is central to how the recall pipeline produces the data RecallCheck indexes.
