A second recall for Mazda6 has been issued in North America due to the invasion of spiders inside the engine vents of the car, Reuters reported.
The smell of gasoline attracts spiders, prompting them to weave webs inside the vents and eventually blocking the engine.
Mazda Motor Corp, who has issued a recall for Mazda6 twice in three years, will be recalling 42,000 sedans with 2.5-liter engines from model years 2010 to 2012 in the U.S., the company told U.S. regulators.
It wasn't immediately clear whether recalls would be made by Mazda officials outside of the U.S.
Due to spider webs blocking evaporative canister vent lines three years ago, Mazda had recalled about 65,000 Mazda6 sedans in North America from model years 2009 and 2010.
The recent recall has been caused by the same problem, Mazda told the National Highway Traffic Safety Administration.
"The web weaved by a spider can lead to a restriction of fuel flow, which in turn can reduce fuel tank pressure when the emission control system purges vapors from the evaporative canister," Reuters reported. "This can put stress on the fuel tank, which may crack and leak fuel, increasing the risk of a fire, a report filed with NHTSA says."
However, the risk of any fires has not been verified, Mazda said.
"In 2011, Reuters reported that the Yellow Sac spider was the culprit in that year's recall. It just likes the smell of gasoline, an auto analyst told Reuters at the time," according to Reuters.
In order to keep spiders from crawling inside, a spring was added to the canister vent line by Mazda as a way to remedy the problem.
"For the most part, that solution worked, but after several reports of cracked fuel tanks in sedans equipped with the spring, Mazda engineers tried to figure out the spider's route to the canister," Reuters reported. "After learning of nine cases in which tanks were damaged even though a spring was loaded, engineers determined that a change in the car's software would keep tanks from cracking even if a spider web blocks a vent."
