The total number of vehicles covered by the recall is 3,791. Waymo filed a voluntary recall with the National Highway Traffic Safety Administration on April 30.In a statement, the company said: "We are working to implement additional software safeguards and have put mitigations in place, including refining our extreme weather operations during periods of intense rain, limiting access to areas where flash flooding might occur."AdvertisementAdvertisementAutomotiveworld reported that NHTSA described Waymo's interim response as a temporary tightening of its operational boundaries, including new weather-related constraints and map revisions, as engineers work toward a full software fix. The recall affects both fifth- and sixth-generation Waymo systems.Because the recall filing required Waymo to enumerate every affected vehicle, the document functioned as an inadvertent census of the company's operations — a level of transparency Waymo rarely provides voluntarily. Active deployments span six metropolitan areas: Phoenix, San Francisco, Los Angeles, Austin, San Antonio, and Atlanta. The tally of 3,791 takes on additional significance given that Waymo did not publicly acknowledge crossing the 2,000-vehicle threshold until September 2025, implying the fleet has come close to tripling within roughly two years, according to Automotiveworld.Regulatory pressure on Waymo extends beyond the flood-related recall. Among the open probes, NHTSA has launched a separate inquiry into a collision that occurred in January when one of the company's vehicles hit a child outside an elementary school in Santa Monica, California; minor injuries were reported.School bus violations have drawn scrutiny from the National Transportation Safety Board as well. Automotiveworld reported that investigators are looking into multiple cases in which Waymo vehicles are said to have rolled past school buses whose warning lights were flashing — conduct that would violate state law. Austin logged at least 20 such episodes between the school year's opening and January; Atlanta recorded six during the same window.AdvertisementAdvertisementOn the question of whether its vehicles should be pulled from areas near schools, Waymo has pushed back, pointing to proprietary data and modeling it says demonstrate a safety advantage over human drivers under similar conditions.
