Alphabet’s (NASDAQ:GOOG) autonomous-driving division Waymo has recalled 3,067 vehicles in the United States due to a software malfunction that has since been corrected through an update, the National Highway Traffic Safety Administration (NHTSA) announced Thursday.
According to the agency, the recall applies to vehicles equipped with Waymo’s fifth-generation automated driving system (ADS). The affected software could cause the cars to continue driving past stopped school buses, creating an elevated risk of collision.
NHTSA said the company deployed a software update to remedy the issue, and all vehicles involved had been updated by November 17.
The announcement follows Waymo’s statement last week that it would initiate a recall after Texas officials reported at least 19 incidents this school year in which the company’s self-driving cars unlawfully passed stopped school buses.
At the time, Waymo said the problem stemmed from software that made its vehicles slow down or stop for a bus but then continue moving. The company added that it plans to monitor performance and apply further updates if needed.
The NHTSA, which launched an investigation into Waymo in October, has requested additional information regarding the Texas incidents, with responses due by January 20.
