Just when you think you've heard everything...
Mazda Motor Corp. has issued a voluntary recall for the second time in three years for it's Mazda6 sedans. The reason? A spider that seems to be attracted to the smell of gasoline.
The spider gets into the engine compartment and builds a web that ends up blocking evaporative canister vent lines. This can lead to a restriction of fuel flow, which might reduce fuel tank pressure when vapours from the evaporative canister are purged by the emission control system. All of this can stress the fuel tank, potentially causing it to crack and leak fuel which might increase the risk of a fire. Mazda says that no fires, accidents or injuries caused by this issue have been reported.
42,000 Mazda6 sedans from 2010 to 2012 with 2.5-litre engines are being recalled in the United States. About 65,000 models from 2009 and 2010 were recalled three years ago for the same reason.
When the problem was initially reported in 2011, the Yellow Sac spider was identified as the culprit. It is attracted to the smell of gasoline. At that time, Mazda's solution was to add a spring to the canister vent line, to keep spiders out. The fix seemed to work for a while, but the company later received at least nine reports of cracked fuel tanks, even in models that were equipped with the spring.
Engineers then got to work figuring out the spider's new route to the canister. They later determined that a software change could prevent fuel tanks from cracking, even if there was a spider web blocking a vent.
For those affected by the recall, Mazda techs will reprogram the car's software, and check the evaporative canister vent line and clear it if required.
Other Mazda models are not affected, and the issue seems to be confined to the cars built at the company's Flat Rock, Michigan plant. Mazda ceased production at this facility in 2012.
This recall gives a whole new meaning to "bug fix".
