Waymo is recalling thousands of its autonomous vehicles due to a dangerous software issue. The Alphabet Inc. (Google’s parent company) subsidiary and autonomous ride-sharing service have recently made headlines for several mishaps that created strange and potentially hazardous conditions for motorists, pedestrians, and riders. Waymo's latest operational issue is leading to its largest recall of 2026 thus far. Here's what Nashville residents need to know about Waymo's latest recall and how it impacts Music City. Why are Waymo autonomous vehicles being recalled? Waymo vehicles are being recalled following an April 20 incident in San Antonio, Texas, where an unoccupied Waymo entered a flooded road going 40 miles per hour. After reviewing the incident, Waymo determined that vehicles with the 5th and 6th-Generation Automated Driving System (ADS) should be recalled. The company is recalling the entire U.S. fleet, 3,791 vehicles, because of a software flaw that could allow vehicles to drive into floodwater after detecting it. There have been no injuries or crashes involving other vehicles related to this specific software flaw. "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," Waymo said in a statement to Reuters. How Waymo is addressing the floodwater software flaw - An over-the-air (OTA) software update for the entire fleet - Active development of a long-term software fix - Limitations on service
