Petrol-sniffing spiders have forced Mazda has issued a voluntary recall notice involves around 42,000 vehicles so it can apply a software fix to its cars.
The yellow sac spider likes the hydrogen oxide found in petrol, and will weave its web in engines, causing a blockage and build-up of pressure.
The problem increased the risk of fire, Mazda said.
A software update will be applied to recalled cars to monitor the pressure level and warn drivers of any danger.
Mazda said it was unaware of any fires being started due to the vulnerability, but it has been a problem that has plagued the company since at least 2009.
Specifically, it is Mazda 6s from the 2010-12 range that are covered by this latest recall.
