Volvo has announced a recall involving 507,000 vehicles worldwide due to a faulty engine component that, in extreme cases, could result in a fire, Automotive News Europe reports. In its own investigations, the Swedish automaker has identified that the plastic engine intake manifold may melt and deform, although cases are very rare.

“In the very worst case, there is a possibility that a localised engine bay fire may occur,” Volvo said. The cars affected by the recall were manufactured from 2014 and 2019 and have a 2.0 litre four-cylinder diesel engine, Volvo said. The affected models are the S60, S80, S90, V40, V60, V70, V90, XC90, and XC60.

So far, no reports of accidents or personal injuries have been detected. Volvo added that all customers will receive a letter, urging them to contact their local retailer for corrective measures. When asked to provide details of the potential financial impact, company spokesman Stefan Elfstrom refused to comment on the cost. All rectification costs related to the recall will be borne by the automaker.
