Toyota said that in affected vehicles, the wire harness which connects to the hybrid power control unit can come into contact with the covering at the connection point.
If dust accumulates on the wire harness or the cover, the insulation on the wires could wear down over time due to vehicle vibrations. This could cause an electrical short circuit, which could generate heat and lead to a risk of fire, Toyota said.
The issue affects vehicles produced in Japan between June 2015 and May 2018, and includes the plug-in version of the Prius and the C-HR compact crossover SUV sold in Japan, Europe, Australia and other countries.
** Anybody knows the exact portion of the wire harness to add extra covering ? **

Recall overview Improvement plot
1. Problem status
In the electrical wiring in the engine room, due to lack of consideration of assembly variation, there is a wiring that interferes with peripheral parts at a place without a protective cover. As a result, the covering of the wiring may be damaged due to vibration during running, causing short-circuiting between the wiring and heating, resulting in burnout. In the worst case, there is a danger of vehicle fire.
2. Content of improvement
Inspect all vehicles, wiring concerned and add protective materials for those with no damage to the covering. Also, if the covering is damaged, replace it with a new one with added protective material.
