Frequently asked questions
Can I misfuel a Hyundai Ioniq 5/6?
There is no petrol or diesel tank. Risk is limited to adding the wrong fluid to the washer reservoir or other caps — never use the charging port for anything except charging.

Do not charge. Isolate the vehicle, contact Hyundai roadside assistance or a high-voltage-qualified workshop. Contamination of HV components is a serious safety issue under HSWA 2015 and the Health and Safety at Work (Hazardous Substances) Regulations 2017.
