Cruise, the self-driving car unit owned by General Motors (GM), has announced the resignation of Kyle Vogt, its chief executive officer (CEO) and co-founder.

He will be replaced by Mo Elshenawy, the current executive vice president (EVP) of engineering at Cruise, who will now serve as president and chief technology officer (CTO) of the company. He will continue his duties as the EVP of engineering in addition to his new role.

Jon McNeill, a recent addition to GM’s board, has been appointed vice chairman of the Cruise board, working alongside Cruise Board Chair Mary Barra. Craig Glidden, a Cruise board member and GM’s EVP of legal and policy, will continue as chief administrative officer at Cruise.

Analyst QuickTake: The resignation comes after recent controversies at Cruise, including having its self-driving vehicle permits suspended due to an accident in October, withdrawing all robotaxis from operations in the US, and issuing a recall for vehicles to update software. It also started laying off its contingent workers earlier this month.
