Toyota Motor Corp. announced a recal of around 1.03 million hybrid vehicles in Japan, North America, Europe and other regions due to an issue with the engine wire harness which can pose a fire risk. The models that are affected includes the plug-in version of the Prius, Prius PHV and C-HR that were produced in Japan between June 2015 and May 2018. In the U.S., approximately 192,000 Toyota Prius will be recalled, produced between the year 2016 to 2018.
Toyota said in a statement that the affected 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.
Toyota has sold more than 10 million units of hybrid gasoline-electric vehicles globally, including the Prius, since 1997. In February 2014, the company announced the biggest recall ever for the Prius with 1.9 million vehicles involved. In 2016, Toyota announced the recall of 3.37 million vehicles globally over problems with air bags and a fuel emission control unit.
