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.
This is the second recall over software concerns this year.
In a recall report of the National Highway Traffic Safety Administration, Waymo says it is updating all 672 of its self-driving vehicles.
The recall cites an “insufficient ability to avoid pole or pole-like permanent objects “ in certain circumstances.
Last month, a Waymo vehicle hit a wooden utility pole trying to perform a low-speed pullover maneuver in a Phoenix alleyway. No passengers were on board.
This also followed a federal investigation launched in May to look into accidents involving driverless Waymo vehicles.
Back in February, Waymo issued a voluntary recall for a different software issue that the company said corrected “a rare scenario” resulting in two incidents, including one in Phoenix that had no injuries but minor vehicle damage.
