Xiaomi SU7 Fatal Crash in Chengdu Puts Electronic Door Safety Under Scrutiny

Police say the driver was suspected of drunk driving, with reported door-access failures drawing regulatory attention.

Overview

  • Videos from the scene show bystanders unable to open the SU7’s doors after the car crashed and caught fire, and police confirmed the 31-year-old driver died.
  • Xiaomi’s Hong Kong-listed shares fell as much as about 8.7–9% intraday before trimming losses, marking their sharpest drop since April.
  • Regulators and industry observers are focusing on electronically actuated and flush door handles, an issue already under review in China and the subject of a U.S. NHTSA probe into Tesla Model Y handles.
  • The Chengdu incident follows an earlier fatal SU7 crash this year and a September over-the-air recall addressing an ADAS highway-assist detection flaw affecting roughly 116,900 vehicles.
  • Xiaomi had not issued a public statement as of the latest reports, and formal investigative findings on the door mechanism and cause remain pending.
