Uber Technologies Inc.'s incoming chief executive officer, Dara Khosrowshahi, inherits an embattled global business with crises sprawling across continents.

Since Uber's founding in 2009, the San Francisco-based company has tested the world's tolerance for disruption and rule-breaking. The company's toe-stepping ways, overseen by co-founder and former CEO Travis Kalanick, helped the ride-hailing company grow to more than 600 cities and a $69 billion (about ¥7.45 trillion) private valuation.

But the startup's aggressive approach left a trail of self-inflicted wounds along the way. Those controversies — including raising doubts about a passenger's rape, the use of software meant to evade law enforcement officials, an intense human resources investigation sparked by sexual harassment charges, and a fierce legal battle with Alphabet Inc.— ultimately felled Kalanick after some of Uber's largest investors asked for his resignation in June.
