Fuel system notes
- Many Hyundai cars have under-rear-seat fuel pump access on front-wheel-drive platforms.
- Diesel CRDi engines need clean fuel — petrol contamination can destroy the high-pressure pump.
- Ioniq 5 and Ioniq 6 are electric only; no petrol or diesel tank.

Frequently asked questions
Does Hyundai UK warranty cover misfuel?
