Honda facing possible venomous spider recall similar to Mazda
Honda has not elevated this situation to a recall, but to acknowledge the possible problem, the Japanese automaker has issued a technical service bulletin (TSB). This explains to dealership technicians how to handle the problem, should they have to work with any 2008-2009 Honda Accord models plagued with the evaporative canister vent tube blockage.
If you missed the initial recall announcement from Mazda explaining their Mazda6 recall, what is happening is that the Yellow Sac Spider is climbing into the vent tube for the emissions evaporative canister and building their sac-style webs. These strong little sacs (which house the spider and its eggs) can get to be strong enough that they prevent the tube from venting during the evaporative purge process. This inability to vent the pressure can cause excessive pressure inside the fuel tank and provided enough of this pressure over a period of time, it can actually crack the fuel tank.
The Mazda6 recall includes cleaning out the vent hose and adding a spring-loaded cap that should prevent the little buggers from getting into the tube. Honda, on the other hand, has simply let their technicians to know to be on the lookout for any problems that could relate to this issue – addressing the problem as needed. Considering that Mazda saw a safety issue with this spider issue, it will be interesting to see if the NHTSA lets the Honda issue slide with just a TSB.
