Japanese car maker Mazda is recalling more than 50,000 Mazda6 cars in US after finding spider web in the vents. The recall also affects another 15,000 vehicle in Canada, Mexico and Puerto Rico.

There doesn't seem to be any particular reason why he's chosen the Mazda6, spokesman Jeremy Barnes said.

The spider's web could clog up the ventilation and put pressure on the tank, leading to a crack which can cause fuel leakage and present the risk of a fire, the carmaker said.

So far the carmaker has identified 20 cases of spider infestation in the Mazda6 cars and all have been in four-cylinder engines, with the V6 engines unaffected.

'A certain type of spider may weave a web in the evaporative canister vent line and this may cause a restriction in the line,' it said in a letter to the National Highway Traffic Safety Administration.

The vehicles affected were built between April 2008 and February 2010, it said.
