Chinese electric vehicle maker Xiaomi Automobile Technology Co. Ltd. has launched a massive recall of 116,887 SU7 Standard Edition sedans, citing a software defect in its Advanced Driver Assistance System (ADAS) that could fail to detect or respond to extreme navigation scenarios, potentially leading to collisions if drivers do not intervene promptly.

The recall, announced today, by China’s State Administration for Market Regulation (SAMR), affects vehicles produced between February 6, 2024, and August 30, 2025—roughly one-third of the model’s cumulative sales of 340,000 units since its March 2024 debut.

Xiaomi confirmed the issue involves its Level 2 highway pilot feature, where the system may provide insufficient warnings or performance in rare, high-risk conditions, such as sudden obstacles or erratic road markings.

No injuries or accidents have been directly linked to this specific flaw, but the move follows intense scrutiny after a fatal March 29, 2025, highway crash in Anhui Province that killed three university students. The Standard Edition SU7, traveling at 116 km/h in Navigation on Autopilot (NOA) mode, veered into a guardrail and burst into flames seconds after the driver disengaged the system.

Xiaomi released vehicle logs showing a two-second obstacle warning, but critics questioned the ADAS's vision-based setup—lacking LiDAR—and door-locking mechanisms that hindered escape. The incident, the model's first reported fatality, prompted Xiaomi's shares to drop 5% and accelerated Beijing's draft rules for Level 2 automation, mandating enhanced safeguards.

To address the defect, Xiaomi will deploy a free over-the-air (OTA) software update via its HyperOS 1.10.0 platform, rolling out immediately to affected owners and extending to the SU7 and upcoming YU7 SUV. The upgrade improves speed adjustments in rain, nighttime driving, and edge-case detection, with no hardware changes required.
