Waymo is recalling more than 600 self-driving vehicles after one of them struck a telephone pole in Arizona.

The recall includes 672 vehicles, which is the entire fleet.

The National Highway Traffic Safety Administration said in its report that last month a driverless Waymo vehicle hit a wooden utility pole in Phoenix, Arizona while it was in an alleyway and trying to perform a low-speed pullover maneuver.

There were no passengers, other road users, or injuries associated with the event, the report said. There was some damage to the Waymo vehicle.

Waymo has completed a software update that improves the automated driving system's response to poles or pole-like permanent objects. It also provided a map update to include a hard road edge between the pole or pole-like object and the driveable surface.
