Mazda has issued a recall of more than 65,000 cars across North America to secure vents against spiders making webs inside them.
Around 20 cases of spiders' web inside vents have been noticed by dealers, and Mazda said it feared the creatures could weave webs inside lines leading into the fuel tank system.
Any blockage in the fuel tank pipes could mean a build-up of pressure, cracks and the risk of fire, the company said. It added that no fires, accidents or injuries related to the problem had been reported so far.
The recall will affects over 50,000 Mazda 6 cars in the US and around 15,000 in Canada, Mexico and Puerto Rico. The cars are 2.5-litre engine models produced between April 2008 and February 2010.
Mazda will notify owners by mid-March to take their cars for inspection and repairs, which would involve cleaning up of the vents and fixing a spring to stop spiders from getting inside.
Spokesman Jeremy Barnes said the webs were linked to yellow sac spiders, he said, but it was unclear why they were crawling into the Mazda 6 rather than other vehicles.
Adding to the mystery, Mr Barnes said the arachnoid attraction to the sporty cars - which the company has marketed with its "zoom-zoom" tagline - had no specific connection to a particular region of North America.
"Perhaps yellow sac spiders like to go zoom-zoom?" he quipped.
