The head of GM's car-sharing service has reportedly left the company (GM)

Julia Steyn, the head of General Motors' car-sharing service, will leave the company, Automotive News reported Monday.

GM did not immediately confirm or comment on the news.

Steyn, a GM vice president, is finalizing her separation terms, according to Automotive News.

The executive started at GM in 2012 after stints at Goldman Sachs and Alcoa. She later took over at Maven, which was founded in 2016 as a separate GM division, concentrating on urban transportation and ride-sharing.

In 2018, Maven unveiled a service that enabled customers who own or lease GM vehicles to offer their cars for short-term rentals.

GM has been undergoing a modest management reorganization. The head of its Cadillac division, Johan De Nysschen, stepped down last year. Also in late 2018, former president Dan Ammann became CEO of GM's Cruise self-driving division. Vice president and product czar Mark Reuss then took over the president position.

CEO Mary Barra has been in the process of positioning GM for a future in which autonomous and electric vehicles will be a bigger business, and when customers may no longer fall into the traditional ownership model.
