Toyota is conducting a safety recall involving certain 2016-2018 model year Toyota Prius vehicles. Approximately 192,000 vehicles in the U.S. will be involved in this recall, and also gasoline-hybrid Prius models, in Japan, North America, Europe and other regions. For more information see the IDTechEx report on Electric Vehicles 2018-2028.
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.
For all involved vehicles, 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 at no cost to customers. All known owners will receive a notification by first class mail starting in late September.
Information about automotive recalls, including but not limited to the list of involved vehicles, is subject to change over time.
