Toyota Motor Corp said on Wednesday it planned to recall about 1.03 million vehicles, including its hybrid Prius gasoline model, in Japan, North America, Europe and other regions due to a problem with the engine’s wire harness, which may represent a fire risk.
Following a national recall announcement by the Japanese Ministry of Transportation, Toyota said that in the affected vehicles, the wire harness that connects to the hybrid power control unit may come into contact with the cover at the connection point .
If dust builds up in the wiring harness or cover, the insulation of the cables may wear out over time due to vehicle vibrations.
This could cause an electrical short circuit, which could generate heat and cause a fire, Toyota said.
The problem affects vehicles produced in Japan between June 2015 and May 2018, and includes the plug-in version of the Prius and the compact C-HR crossover SUV sold in Japan, Europe, Australia and other countries.
Approximately half of the withdrawals would be made in Japan, said Toyota spokesman Jean-Yves Jault.
Only the Prius model would be removed from the market in the United States, where around 192,000 vehicles were affected, he said.
