Toyota is recalling over a million vehicles worldwide in one of their biggest recalls ever.
The recall is specifically regarding Toyota’s hybrid vehicles since it has to do with a potential wiring fault that could lead to a fire. Which is what most people would consider to be bad--nobody wants to wake up one morning to their house on fire because they owned a Prius.
Reuters reports that the recall would affect 1.03 million vehicles around the world. The recall was announced Wednesday and is calling for the return of certain hybrid vehicles in Japan, North America, Europe, Asia Pacific, and other regions.
It all has to do with the engine wire harness that connects to the hybrid power control unit. Since everything is electrified in a Prius, the engine is much more full of wires than a regular car and those wires are much thicker to deal with all the current that’s passing through them.
However, that size is proving to be a problem. The wiring harness can come into the contact with the engine covering at a connection point, and if dust and dirt have accumulated on either the wiring or the engine cover, it can act like an abrasive surface and slowly wear away the insulation while the car vibrates during normal operation.
Long story short, the insulation can come off, the wires can come into contact with each other, cause a short, and then start a fire.
The recalled models are all made between June 2015 and May 2018 and is for both the plug-in Prius as well as the C-HR compact crossover SUV. Half of the 1 million vehicles would be recalled in Japan, while the US will see about 192,000 vehicles recalled--all of them Priuses.
There has only been one noted incident where a Prius has caught fire, and it happened in Japan. All the same, it’s probably a good idea to take some precautions if you’re a Prius owner. Maybe store your car on the street for the time being and not take too many drives on the highway.
