Mazda 6 charcoal canister malfunction causing fuel collection and fire hazard on Mazda 6

Some Mazda 6 owners report experiencing issues related to a malfunctioning charcoal canister, which can lead to fuel collection and pose a fire hazard. A faulty charcoal canister may trigger the P0443 trouble code, impacting the EVAP system and potentially causing fuel leaks. If the canister is damaged or clogged, it increases the risk of fire hazards, especially if the fuel tank is overfilled, allowing gas to flow into the canister. Common symptoms reported include the check engine light illuminating, difficulty filling the fuel tank without spills, and hissing noises when opening the fuel cap. To mitigate these risks, it is essential for owners to inspect the charcoal canister and replace it if air leakage is detected, ensuring safe operation of their Mazda 6.
