Uber Technologies’ board was sued on Monday by shareholders who accused management and directors of letting the ride-sharing company cut corners on compliance, leading to thousands of lawsuits ​from people alleging sexual assault and harassment.

In a complaint ​filed in San Francisco federal court, shareholders led by a Detroit pension fund said board members ignored repeated internal and external warnings about Uber’s alleged failure ​to address sexual abuse by drivers.

Shareholders said oversight failures were also ⁠a factor in two lawsuits filed ⁠last year by the federal government. One accused ‌Uber of routinely refusing to serve disabled passengers, including people with service animals or stowable wheelchairs. The other alleged deceptive billing and cancellation practices in the Uber One subscription service.

“Uber is a serial compliance offender,” whose reputation has been “irredeemably damaged” ⁠by negative media coverage, the complaint said.

Uber’s ride-hailing service is a popular way to get around, but the Fifth Estate is looking into the company’s track record and why some customers are calling for a better screening process for Uber drivers.

A spokesperson for San Francisco-based Uber said the lawsuit “ignores important facts and is based on misleading, false narratives from other meritless lawsuits that we have already addressed ‌publicly and in the courtroom.”

Lawyers for the shareholders, led by the Police and Fire Retirement System of the City of Detroit, did not immediately respond to requests for comment.

Monday’s so-called derivative lawsuit seeks to require directors to reimburse Uber for their ​alleged breaches of fiduciary duties and violations of securities law, with any proceeds benefiting shareholders.

Chief Executive Dara Khosrowshahi is among ⁠the defendants. Shareholders said that in nearly nine years as chief executive, he has been “less brazen in ⁠pushing regulatory limits” than his predecessor, but continued to skimp on compliance.

As of June 1, ⁠Uber ⁠faced 3,571 lawsuits in litigation ​overseen in the San Francisco court accusing drivers of sexual misconduct.

Shareholders said Uber’s board has been told ​repeatedly that fewer than 40 per cent ⁠of users believe the company takes safety seriously.

Earlier this month, Uber and rival Lyft sued New York City to block a new law they said would prevent them from getting rid of bad drivers who threaten passenger safety.

Uber’s share price has fallen by more than 25 per cent since peaking last ⁠September 22.
