Uber’s Global Vehicle Program Chief Quits

Sherif Marakby, the former Ford Motor Co. executive who joined Uber Technologies Inc. a year ago to become the ride-sharing company’s vice president of global vehicle programs, has quit.

Marakby had been Ford's head of global electronics and engineering before joining Uber. It isn’t clear what he plans to do next.

His departure is the latest among the ranks of Uber’s leadership. Last week Rachel Whetstone, who headed policy and communications for the past two years, quit. Other executives who left this year are President Jeff Jones, engineering chief Amit Singhal and Ed Baker, who oversaw product and growth. Last month Gary Marcus stepped down four months after being named director of Uber's new artificial intelligence lab.

Uber has been swamped with multiple controversies, including some that were self-inflected. The company faces driver complaints about payment policies and a lawsuit alleging that it is using data stolen from Alphabet Inc.’s Waymo autonomous car company.

News also surfaced last month that Uber was using a software program called “greyball” to hide its activities in markets where the company’s services are banned. And CEO Travis Kalanick declared in March that he needs “leadership help” after a video showed him berating an Uber driver about wages.
