WASHINGTON (Reuters) -More than two dozen unions urged U.S. auto safety regulators on Thursday to open an industry-wide probe into driverless vehicles including Alphabet’s Waymo and’s Zoox.

The unions, including the Transportation Trades Department, Transport Workers Union of America, Teamsters and United Auto Workers, cited the recent investigation into General Motors’ self-driving unit Cruise and California’s decision to suspend Cruise testing.

Driverless vehicles “are unsafe and untenable in their current form. This industry is in dire need of federal regulation and leadership to restore a modicum of safety and establish a realistic path for these vehicles to operate without threatening other road users,” they said in a letter to Transportation Secretary Pete Buttigieg and Ann Carlson, acting administrator at the National Highway Traffic Safety Administration (NHTSA). The letter also said workers are facing safety issues from robotaxis.

“NHTSA must initiate an industry-wide investigation to determine the true extent of the safety failures behind the scenes,” the letter added.

Waymo, Zoox and NHTSA did not immediately respond to requests for comment.

The letter said it is time for NHTSA to “step up its regulatory authority to ensure these vehicles are being operated responsibly and with the serious oversight they require.”

In March, NHTSA said it was probing the self-certification by Zoox in 2022 of a robotaxi without traditional driving controls.

Cruise on Wednesday recalled 950 driverless cars from the roads across the United States following a crash involving one of its robotaxis and will likely issue more recalls.

Last month, a pedestrian in San Francisco was struck by a hit-and-run driver and thrown into an adjacent lane and was hit a second time by a Cruise robotaxi that was not able to stop in time and then dragged the pedestrian.

Cruise last month said it would halt operations nationwide after California regulators suspended the robotaxi operator’s license, saying the Cruise self-driving vehicles were a risk to the public. The company on Monday said it is temporarily halting production of its fully autonomous Cruise Origin.
