General Motors Co.’s autonomous-vehicle business, Cruise, plans to resume service gradually after a series of missteps led it to halt all robotaxi operations last month.

Cruise President Mo Elshenawy told employees in an email Wednesday that the company will eventually restart in a single city. It will focus in the near term on retrofitted Chevrolet Bolts while delaying plans for its driverless Origin vehicle, according to the email, details of which were confirmed by a spokesperson.
