Product Recall 1 What: Mazda 6 Cracking of Gas Tank due to Spider Webs Recall Date: March 14, 2014 [1] Why: On certain Mazda6 vehicles, a certain type of spider may weaver a web in the evaporative canister vent line, potential causing a restriction in the line. If this occurs, the fuel tank pressure may become excessively negative when the emission control system works to purge the vapors from the canister. As the canister is purged repeatedly during normal operation, the stress on the fuel tank may eventually result in a crack, potentially leading to fuel leakage and an increased risk of fire. [1] Incidents: A similar recall was issued in 2011 regarding the same spider related cause, for 65,000 vehicles. A solution was implemented in the form of the installation of a spring inside the canister to prevent spiders from crawling inside [2]. However, a report was received in November 2011, for the same issue on a vehicle with the spring installed. A second report was received regarding the same cause in September 2013 [1]. Number of Units Sold: 42,000 [1]. When Sold: 2010 – 2012 Model Year equipped with 2.5L engine built from September 14, 2009 through May 2, 2011 [1] ETM627 Tie Duan – Mazda6 Spider Gas Tank Recall 11/25/14
