Volvo Cars has recalled more than 500,000 vehicles around the world for possible engine fires.

Volvo said Wednesday that the intake manifold inside the engine is rare but melted and deformed, and in the worst case could lead to engine fire, the Guardian of the United States and Bloomberg reported.

S60, S80, S90, V40, V60, V70, V90, XC60, and XC90 were produced for the four-cylinder diesel engine vehicles from 2014 to 2019.

Volvo said there were a few cases of fire, but no injuries.

A letter was sent to the recalled car owners, advising them that they should still be able to use the car, but be aware of the possibility of a problem, and pay attention to whether the engine warning light is on.

"We are taking this situation very seriously and are working to correct the defect," Volvo said in a statement.

In January, Volvo recalled 219,000 diesel-powered vehicles, including the XC60 and XC90, sold in 2015 and 2016, to fix the risk of fuel leaks in the engine area.

Volvo was a preventive measure at the time.

Volvo, a car company in Sweden, is now the largest shareholder in China.

Jiji Cha became the largest shareholder in 2010 when he bought shares from Ford Motor Company.
