The yellow sac spider likes to stay warm and it apparently like to go zoom, zoom. This has led to the recall of 52,000 2009-2010 Mazda 6 vehicles in the United States. The spiders weave their webs in the evaporative canister vent line, restricting the line and causing pressure to build up which could cause the fuel tank to crack and leak. Who would have guessed that in a fight between a car and a dime sized spider the arachnid would come out on top? If you drive the four-cylinder version you can take it to a dealer who will inspect the vent tubes, remove webs and insert a spring to keep the spiders out.
