Ignoring a faulty fuel cap can lead to long-term consequences in the Alsvin. A persistent EVAP system leak due to a loose o r cracked cap causes check engine lights, which may mask other issues. It can also cause gradual fuel evaporation, reducing efficiency and increasing pollution. Over time, this might damage EVAP components like the purge valve o r charcoal canister, which are more expensive to replace. Moreover, a lingering fuel odor around the vehicle poses a safety hazard, especially in enclosed spaces like garages.
