Mazda is recalling certain Mazda6 sedans from the 2009 and 2010 model years to clean the cobwebs out of their fuel systems.
The car maker says the recall, which affects about 65,916 cars built from April 8, 2008 through Feb. 8, 2010, was brought on by a certain kind of spider called the Yellow Sac. The spider may weave a web in the vent line for the car’s evaporative canister. The web can cause a restriction in the line, which can result in excessive negative pressure (vacuum) in the fuel tank, reported The Wall Street Journal.
The pressure buildup can occur during normal operation when the emission-control system purges vapors from the canister. These purges happen repeatedly as the car is driven and the resulting stress on the tank can cause it to crack.
In a document filed with the National Highway Traffic Safety Administration, the company said its technicians noted two instances of cracked fuel tanks in 2009 and in the second case they found the web clogging the vent line.
Mazda spokesman Jeremy Barnes said it is unclear why the spiders were attracted to the Mazda cars. “Perhaps they enjoy cars that are fun to drive.”
On the serious side, he said fuel leaks are potentially dangerous so the company plans to begin the recall on or before March 25. Dealers will inspect and clean the canister vent line, and install a spring to prevent the spider from getting into the line. This service is free of charge.
