Xiaomi to update 116,000 SU7 EVs due to self-driving software issue

Xiaomi is recalling a big chunk of the SU7 cars, its debut model. The company found a software defect in its driver-assistance feature that could pose a safety risk in specific situations. The recall affects nearly 117,000 vehicles and comes months after a fatal crash involving an SU7 brought increased scrutiny to the new electric vehicle maker.

The recall was announced through China's State Administration for Market Regulation (SAMR), and it targets 116,887 units of the SU7 Standard Edition. These electric cars were manufactured between February 6, 2024, and August 30, 2025.

According to the regulatory filing, the problem is with the Level 2 highway pilot driving assistance function. The system may have "insufficient recognition, warning, or handling capabilities in extreme special scenarios." In plain English, the car's computer might not react correctly or quickly enough in unusual road conditions, increasing the risk of a collision if the driver isn't paying close attention.

For SU7 owners, the fix will not require a trip to the dealership. Xiaomi announced it will push a free, over-the-air (OTA) software update to all affected electric cars. This update will upgrade the vehicles to the latest Xiaomi HyperOS 1.10.0 system.

The company's new electric SUV, the YU7, will also receive this software update, highlighting a key advantage of modern EVs, where critical safety issues can often be resolved with a software patch downloaded directly to the car, much like an update for a smartphone.

This recall is an important event for the young carmaker. The 116,887 SU7s being recalled represent roughly one-third of all SU7 models sold since the car's launch on March 28, 2024. The SU7 sedan has been a hit for the brand, with sales reaching 339,421 units by the end of August, and making up nearly 89 percent of Xiaomi's total EV sales.

The software concerns came to light after a tragic incident from late March 2025. A Xiaomi SU7 was involved in a fatal accident after it collided with a highway guardrail at 60 mph and caught fire, resulting in three deaths.

According to Xiaomi's statement at the time, the SU7's assisted driving feature was active but was disengaged just one second before the impact, as the driver took back control. The company stated that the system had issued a warning about obstacles ahead.

Level 2 automation, the system at the center of the recall, provides steering, acceleration, and braking support but still legally requires the driver to remain fully engaged and ready to take control at any moment. It seems the 'smart' in smart driving still requires a very smart human to be paying attention.
