Description

Waymo issued a voluntary recall of 1,212 vehicles due to a software issue causing collisions with roadside barriers, gates, and chains.

Multiple low-speed collisions were reported across Waymo's operating territories. No injuries resulted from these incidents but vehicle and property damage occurred.

Resolution: software recall and OTA update to improve barrier detection

Root Cause

perception deficiency

Perception system failed to reliably detect thin, low-contrast, or flexible barriers such as chains, gates, and flexible bollards; these objects fell outside the trained detection model's reliable performance envelope

✅ Confirmed

Systemic Issues

  • Thin and low-contrast objects remain a challenging perception edge case
  • Parking lot and driveway environments have diverse barrier types
  • Pattern of repeated collisions before recall indicates detection gap was systematic
  • Largest Waymo recall to date at 1,212 vehicles

Regulatory Action

NHTSA recall. Waymo issued voluntary recall and deployed OTA software update to improve detection of thin barriers, gates, and chains.
