Just like Toyota, Mazda's also recalling cars due to a nasty bug -- the difference is, Mazda's problem involves real, live multi-legged creatures. Apparently, the company's recalling roughly 42,000 Mazda 6 sedans in the US, because of a certain yellow sac spider with a penchant for the smell of gasoline. If this spider makes the engine its home, the webs it'll inevitably weave could block fuel flow and increase internal pressure. This, in turn, could lead to cracks and fuel leaks that increase the risk of fire, though the automaker claims it has yet to receive complaints about spontaneously combusting sedans.
In 2011, Mazda recalled cars for the exact same reason, and thus has started putting covers on vent lines to prevent the spiders from crawling in. Unfortunately, the company recently found out that the spiders can still wreak havoc -- they can go through the preventative measure Mazda added, prompting this development. Not sure if you need to turn your car in? If it's a 2010 to 2012 model with a 2.5-liter engine, then the Japanese auto manufacturer might call you up as soon as this month. Mazda will update your car's software to prevent pressure from building up inside the fuel tank, just in case one of the gas-loving spiders crawl in.
