2026 Kia Sportage Fuel System Problems

Your car's fuel economy has been significantly worse than expected since you purchased it in September 2025, with actual mileage around 16-17 mpg instead of the EPA rating on the window sticker. When a check engine light appeared in December, the dealership found that your EVAP canister was split open and the under-shield was damaged—they claimed you caused the damage, but you haven't hit anything and there's no other undercarriage damage. The dealership says this damage is responsible for the poor fuel economy and is not covered under warranty, though you reported low mileage immediately after purchase, long before any visible damage occurred. The repair will likely involve replacing the EVAP canister and repairing or replacing the under-shield.
