A spokesperson for Cruise said Kan announced his resignation in a Slack message. The company and Kan offered no other details.
In his message to employees, seen by Reuters, Kan noted that Cruise had been serving 10,000 rides per week. “I know Cruise will achieve that again soon,” he wrote.
Vogt, 38, offered little in the way of explanation, stating simply “I have resigned from my position” in an email to staff viewed by Reuters on Sunday.
Cruise’s woes are also a setback for an industry dependent on public trust and the cooperation of regulators. The unit had in recent months touted ambitious plans to expand to more cities, offering fully autonomous taxi rides.
Vogt’s resignation came after GM and the board at Cruise increased their scrutiny of its leadership.
Cruise is retrenching after an October accident that ended with one of Cruise’s self-driving taxis dragging a pedestrian. Cruise pulled all its vehicles from testing in the United States to conduct a safety review.
Kan didn’t immediately respond to a request for comment Monday.
Vogt over the weekend apologized to staff for the company’s continuing troubles. “I take responsibility for the situation Cruise is in today,” he wrote in an email. “There are no excuses, and there is no sugar coating what has happened.”
