Waymo Recalls Nearly 4,000 Robotaxis Over Construction-Zone Software Defect

Recall Overview: Software Fault Leads to Construction-Zone Intrusions
Waymo recalled between 3,871 and 3,900 robotaxis after NHTSA identified a software defect that could let the vehicles enter closed freeway construction zones at speed. The defect affects all fifth-generation ADS (Jaguar) robots, and Waymo paused freeway operations while a fix is built.
Incident Summary & Timeline
Six Phoenix incidents on SR 51 (April 11, 19) missed ramp-closure signs; seven San Francisco Bay Area events (May 18-19) drove between cones in active lane closures. NHTSA recorded 13 incidents; all fifth-generation vehicles share the defect.
Safety Impact
The defect could let autonomous cars travel at posted speed through work zones, which NHTSA says “increases the potential for collisions.” Freeway suspension cuts Waymo’s service in Phoenix, San Francisco, Los Angeles and Austin, briefly aiding rivals.
Official Responses
Waymo said it identified an area of improvement around freeway construction zones, voluntarily restricted freeway operations, notified regulators and filed a voluntary software recall with NHTSA. The firm added it still serves surface-street riders and that its mission is to be the world’s most trusted driver. NHTSA described the fault as a failure to recognize or correctly prioritize construction-zone conditions.
Criticism & Ongoing Investigations
Regulators opened a separate NHTSA probe into a January 2026 collision that injured a child near a Santa Monica school. Critics warn repeated recalls may erode public trust and give competitors a narrative edge before Waymo’s planned launches in London, Denver and other markets.
Passenger Account
Elliot Slade, a passenger in a May incident, said the robotaxi “sped through a construction zone… we’re dead,” before it left the highway for a residential street. No injuries were reported.
Conflicting Figures
Sources list the recall size as “nearly 4,000” (ABC15, Fox Business), 3,900 (CNET, Bloomberg) or 3,871 (NHTSA filing). The notice confirms all fifth-generation vehicles are affected, but the exact fleet count remains unclear.
Key Quotes
- “Waymo’s mission is to be the world’s most trusted driver, and the data shows that we’re making roads safer in the communities in which we operate.” — Waymo spokesperson
- “We identified an area of improvement regarding performance around freeway construction zones.” — Waymo spokesperson
- “Driving at speed in a freeway construction zone increases the potential for collisions.” — NHTSA statement
- “The Waymo started freaking out as we got closer to the merge cause the lanes were kind of all merging… we’re dead.” — Elliot Slade, passenger
Future Actions
Waymo is building an over-the-air update to improve construction-zone detection and adjust priority logic. After validation, the fix will be deployed and freeway service is expected to resume. Surface-street rides continue, and the firm readies expansions in London, Tokyo and additional U.S. cities.
