P0440 on the All-New 2024 Hyundai Santa Fe
The 2024 Hyundai Santa Fe is a complete redesign with bold new styling and an updated 2.5L turbo engine (277 hp) paired with an 8-speed DCT. If your new Santa Fe has triggered P0440, the EVAP system has detected a malfunction. On a brand-new platform, the cause is often simple and covered by warranty.

Your Santa Fe drives, tows, and handles normally. All systems function as designed.
