Breaking: Xiaomi will push an over-the-air (OTA) update to roughly 115,000 SU7 sedans to address an assisted-driving warning/engagement gap identified by China’s auto safety regulator. The company says driving functions remain available and that the fix adds clearer prompts and tighter hand-off behavior for the Advanced Driver Assistance System (ADAS). No workshop visits required.
What changed and why it matters
The update focuses on edge cases where drivers might over-trust lane-keeping and traffic-jam assist. Expect more assertive steering-wheel torque checks, earlier visual/audible prompts, and revised deceleration logic when the car judges the driver isn’t engaged. Xiaomi also says it’s improving the dashboard state indicators so drivers can immediately tell whether the system is in standby, active assist, or safe-stop mode.
The broader context: China tightens ADAS messaging
Beijing has leaned on EV makers to tone down “autopilot”-ish marketing and to make human-in-the-loop limits unmistakable. For Xiaomi, a fast-growing entrant whose SU7 has built momentum against Tesla Model 3 and local rivals, the calculus is simple: fix the messaging and the hand-off frictions before they become brand-dragging events. OTA keeps customer pain to a minimum and demonstrates a mature software cadence.
Analysis: the new ADAS playbook
- Safety UX is the product. With feature parity across brands, the next battleground is how cars explain their intent and limits. Clearer prompts, graduated interventions, and graceful degradation are becoming purchase drivers.
- Regulatory alignment beats headline features. China’s regulator is nudging ADAS toward conservative defaults. Vendors that ship fast but fail to align will end up shipping twice.
- Fleet learning loop. Xiaomi’s OTA implies upstream telemetry and A/B guardrail tuning. Expect recurring safety releases with measurable changes to disengagements and driver-monitoring events.
What SU7 owners should do
- Install the OTA promptly (Settings ► Vehicle ► Updates). Keep the vehicle parked with sufficient battery charge.
- After updating, review the revised ADAS status icons and prompts in the driver display, and re-enable your preferred assist features.
- Use two-hands-on-wheel driving on all roads. Treat ADAS as “assist,” not “automation.”
Market impact
In the short term, this is a reputational stabilizer for Xiaomi as delivery volumes scale. Medium-term, expect similar OTA hygiene across the Chinese EV field—more frequent nudges, stricter attention checks, and more transparent driver scoring. The winners will be those who make safety UX feel intuitive, not punitive.
