    Subject: Safety Recall J0T– Remedy
    2016 – 2018 Model Year Prius Engine Wire Harness

    On September 5, 2018, Toyota filed a Defect Information Report (DIR) with the National Highway Traffic Safety Administration (NHTSA) informing the agency of our intent to conduct a voluntary Safety Recall on certain 2016 – 2018 model year Prius vehicles.

    Condition:
    The subject vehicles have an engine wire harness which is connected to the hybrid vehicle Power Control Unit. A portion of the wire harness could contact the cover at this connection and wear over time, causing an electrical short circuit, which can generate heat. If sufficient heat is generated, there is an increased risk of a vehicle fire.

    Remedy:
    Toyota dealers will check the engine wire harness assembly. If a wire core is exposed, the engine wire harness assembly will be replaced with a new one that includes a protective sleeve. If a wire core is not exposed, protective tape will be installed on the engine wire harness assembly. The repair will be performed FREE OF CHARGE to customers.

    Covered Vehicles:
    There are approximately 192,300 vehicles covered by this Safety Recall. There were approximately 200 vehicles distributed to Puerto Rico covered by this Safety Recall.

    Owner Letter Mailing Date:
    Toyota will begin notifying owners within September 2018


    Frequently Asked Questions

    What is the condition?
    The subject vehicles have an engine wire harness which is connected to the hybrid vehicle Power Control Unit. A portion of the wire harness could contact the cover at this connection and wear over time, causing an electrical short circuit, which can generate heat. If sufficient heat is generated, there is an increased risk of a vehicle fire.

    Are there any warnings that this condition will occur?
    No. In some cases, if this condition does occur, a warning light could illuminate, depending on the extent and location of the damage.

    What is Toyota going to do?
    Toyota dealers will check the engine wire harness assembly. If a wire core is exposed, the engine wire harness assembly will be replaced with a new one that includes a protective sleeve. If a wire core is not exposed, protective tape will be installed on the engine wire harness assembly. The repair will be performed FREE OF CHARGE to customers.

    Toyota will send an owner notification, beginning in September, by first class mail advising owners to make an appointment with their authorized Toyota dealer to have the remedy performed.


    Which and how many vehicles are covered by this Safety Recall?
    There are approximately 192,300 vehicles covered by this Safety Recall.

    Why are Prius Prime vehicles not involved in this Safety Recall in the U.S?
    The routing of the engine wire harness in Prius Prime vehicles distributed to the U.S. is different from Prius Prime vehicles in certain other markets. Therefore, Prius Prime vehicles distributed to the U.S. are not affected by the condition.

    How long will the repair take?
    Inspection of the wire harness and installing the protective tape will take approximately 45 minutes. If the inspection determines that the wire harness needs replacement, the repair will take approximately 5 hours. However, depending upon the dealer’s work schedule, it may be necessary to make the vehicle available for a longer period. If wire harness replacement is necessary, the dealer may offer you a loaner vehicle.

    What if I have additional questions or concerns?
    If you have additional questions or concerns, please contact the Toyota Customer Experience Center at 1- 888-270-9371 Monday through Friday, 7:00 am to 7:00 pm, Saturday 7:00 am to 4:30 pm Central Time.

    I don't know if other Techs noticed but Toyota updated the procedure and time for taping the second wiring harness. I submitted a few pic's showing the other harness having chaffing marks also....
