Voice command bug allegedly turned off headlights and caused crash in China

Mar 1st 2026

A vehicle owner in China says a voice command meant to turn off interior lights disabled the headlights and caused a crash; Lynk & Co issued an emergency OTA patch and owners of other brands reported similar voice command vulnerabilities.

  • A Lynk & Co Z20 driver says a voice request to turn off interior lamps instead disabled the headlights and led to a crash into a median.
  • Dashcam footage reportedly shows the crash after the driver could not re-enable headlights and the voice system replied that the operation could not be completed.
  • Lynk & Co posted on Weibo that it pushed an emergency over the air update to prevent headlights from being disabled by voice in unsafe conditions.
  • Owners of other brands including Zeekr and Deepal tested broad commands like "turn off all lights" and found similar vulnerabilities on their vehicles.
  • It is not yet clear whether cars sold outside China or by other automakers are affected by the same issue.
