A cyber breach at **Hyundai AutoEver America (HAEA)**, the IT services division supporting Hyundai, Kia, and Genesis, exposed the personal data of up to **2.7 million U.S. vehicle owners** in **March 2025**. Hackers gained unauthorized access to HAEA’s IT environment, compromising **sensitive information**—including **Social Security numbers (SSNs), driver’s license details, names, and potentially other identifiers**—linked to over **2 million users and nearly 3 million vehicles**. The stolen data heightens risks of **identity theft, financial fraud, and long-term reputational damage** to Hyundai’s connected vehicle ecosystem. While the exact victim count remains unclear, state filings in **Massachusetts and Maine** confirm broad exposure. HAEA has initiated **customer notifications and credit monitoring**, but criticism persists over **delayed transparency and systemic vulnerabilities** in automotive IT infrastructure. The breach follows a **2023 incident** affecting European customers, reinforcing concerns about **recurring security gaps** in the sector. Legal firms are exploring **class-action lawsuits**, and regulators may impose penalties under laws like **CCPA**.
