It seems that Yellow Sac spiders really, really love Mazda. Three years after Mazda recalled 52,000 Mazda6 sedans over spider webs obstructing the evaporative canister vent lines of 2009 and 2010 Mazda6 models, another recall has been issued for 42,000 more of the models built between 2010 and 2012 and equipped with the 2.5-liter four-cylinder engine.

According to the automaker, there have been nine confirmed sightings of spiders in vent lines since the original recall. It seems that covers were applied at the factory to keep the arachnids from entering, but it hasn't quite exterminated the problem. A reflash of the ECU is required that "[changes] the logic behind how the car purges the charcoal canister during normal operation," says Jeremy Barnes, Director, Public Relations & Brand Experience at Mazda North American Operations.

So far, Mazda has not recorded any fires, accidents or injuries due to this tangled mess of webs. Recall notices will be mailed out to owners later this month.

"This is a follow-on to a recall we had a few years ago that you probably remember, where a certain type of spider – the Yellow Sac spider, to be specific – is attracted to hydrocarbons and built a web in a vent line. We installed a cover on the line that stopped the spider entering it, and did a reprogram of the ECU to change the logic behind how the car purges the charcoal canister during normal operation. Subsequent to the recall, we made a running change to install the cover on all cars at the factory, but did not apply the ECU logic change. We are now applying that logic change through a reflash of the ECU. It will cover cars in the US too, with notices going out to customers later this month.

While, in extreme cases, the purging of the canister may cause the tank to become damaged if the line is blocked, there have been no fires, accidents or injuries tied to this situation."

RECALL Subject : Spiders may Block Fuel Tank Vent Line

Report Receipt Date: MAR 11, 2014
NHTSA Campaign Number: 14V114000
Potential Number of Units Affected: 42,000
Manufacturer: Mazda North American Operations

Mazda North America Operations (Mazda) is recalling certain model year 2010-2012 Mazda6 vehicles manufactured September 14, 2009, through May 2, 2011, and equipped with 2.5L engine. In the affected vehicles, spiders may weave a web in the evaporative canister vent hose, blocking it and causing the fuel tank to have an excessive amount of negative pressure.

Negative pressure could cause the fuel tank to crack resulting in a fuel leak, increasing the risk of a fire.

Mazda will notify owners, and dealers will reprogram the powertrain control module and inspect and clean the canister vent line. If a web was found in the line, the fuel tank and check valve on canister vent line will be replaced. These repairs will be done free of charge. The recall is expected to begin in April 2014. Owners may contact Mazda at 1-800-222-5500. Mazda's recall number associated with this campaign is 7214C.

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to

      I hate spiders and I'll shamelessly admit I'm deathly afraid of them.

      This is a pretty awesome marketing scheme. Mazda is cashing in on all the negative press GM has stirred up by asserting themselves as a brand that will recall a vehicle for the smallest defects. Brilliant!

      I bought my 2013 Mazda 3 back in August. Not sure how long it was sitting on the lot, but within the first week I found 3 or 4 yellow spiders inside the car, mostly crawling on the inside of the windshield. They were crawling through a hole in the headliner where i'm assuming wires would go for an accessory. You can bet I brought it in and had them look, no way in hell was I removing anything to find a thousand eggs or something. They said they didn't see anything and I haven't seen any since... #knockonwood

        They're harmless spiders...every spring I see a few spiderwebs and spiders in my car and they go away when it gets colder. Usually I try to catch them and release them outside. The first time one dropped onto me while driving I did freak out a little but most species are pretty harmless. As long as you don't have a really poisonous species in your car you're fine and most of those aren't big web weavers.

      Such a fantastic car that even the arachnids love it.

      I agree with dafusom, I own and operate a 2008 Mitsubishi Lancer GTS that has 122,689 miles on it, and the engine sounds like it did the day I bought it, which was March 21, 2007. The car handles like a dream, is the best looking compact on the market, and shows no signs of slowing down at all. This car is an absolute gem. As for Mazda, I've never seen one of their cars I'd want ta part pesos with. Until I saw the 2015 Mazda Hazumi pics released about a month ago. The Hazumi is the name of the concept car that will turn in to the new Mazda 2. Now that car deserves a decent test drive in late 2014 sometime, no doubt!

      We fog our basement and garage once a year takes care of everything. I would check before doing it to your car but it will kill anything living in it.

        Not sure I'd want to sit in the car after it's been fogged. I'd try taking a road trip to some place very very hot (death valley?) or very very cold (skiing), and leave the car parked outside for a couple of days. The spiders might leave, die, or hibernate. If they hibernate, they'll be back unfortunately.

      You shouldn't have anything living in your car. These things can bite and should be treated.

      Mazda:you are unclear of the concept. In the automotive world it is "Spyder", and refers to a variety of car.

      I was hoping the unification with Alfa Romeo and Mazda the return of the spiders meant something totally different.
