Interim notices informing owners of the safety risk are expected to begin October 22, 2018. Owners will receive a second notice when the remedy becomes available. Owners may contact Toyota customer service at 1-888-270-9371. Toyota’s number for this recall is J0V. Note: The software updates in this recall are needed even if the vehicle had the software previously updated under recalls 14V-053 or 15V-449.
