Waymo had to recall a similar number last month after it discovered a bug that allowed AVs to drive onto flooded roads.
A new recall notice shows that Waymo is pulling out nearly 3,900 robotaxis from US streets over a software issue that lets autonomous vehicles (AV) enter and drive on closed freeway construction zones.
This comes just a month after the company had to recall a similar number of cars after it found a different bug that allowed its AVs to drive onto flooded roadways.
“Under certain circumstances”, Waymo’s fifth-generation automated driving system software (ADS) could allow AVs to enter and drive “at speed” in freeway construction zones, the safety recall report filed with the US National Highway Traffic Safety Administration (NHTSA) on 17 June read.
The ADS in question is unable to recognise construction zones, or “inappropriately” prioritises avoiding other freeway hazards, the document showed. Waymo said it owned all of the 3,871 robotaxis it is recalling.
