Toyota is recalling 73,000 Corolla Cross Hybrid vehicles from 2023 to 2025. They don't make enough noise when backing up, so pedestrians can't hear them coming.
Federal law requires electric and hybrid vehicles to emit warning sounds at low speeds. These Corolla Cross Hybrids fell short of that standard while in reverse. NHTSA flagged the safety issue.
Dealers will update the software through an OBD-II diagnostic port at no charge. The process takes minutes. Owner notifications begin by May 30, 2026.
Watch whether Toyota reports any pedestrian incidents involving these vehicles and whether other hybrid makers face similar recalls.
