⚠️ Genesis G70 — Moderate misfuel risk
NZ G70 is petrol only — diesel in petrol is the main forecourt error.
If the engine was not started
Do not start the engine or cycle the ignition to RUN (diesel pre-heat). Have the vehicle recovered if needed and tank drained before any crank attempt.
If the engine was started
If the engine ran, spark plugs, injectors, catalytic converter, and filters may need replacement after draining and flushing per OEM limits.
⚠️ Genesis position — G70
Genesis warranty excludes contaminated fuel. Follow Genesis NZ repair procedures shared with Hyundai-Kia N platform hardware.

Frequently asked questions
What if I put diesel in my petrol Genesis G70?
Do not start the engine. Diesel in a petrol tank will not ignite easily but can foul spark plugs and the fuel system. Drain the tank per OEM procedure and replace filters as specified.
Will misfuel damage void my Genesis warranty in New Zealand?
Genesis warranty terms typically exclude damage from incorrect fuel or contaminated fuel. Keep invoices from an authorised repairer or NZIFDA-certified operator; disputes may be referred to the Disputes Tribunal or Motor Vehicle Disputes Tribunal.
Where is the fuel pump access on a Genesis G70?
On most NZ-market examples, access is via a service panel under the rear seat or in the load area — confirm in Genesis workshop manuals for your chassis code. Saddle-tank designs may need both sides drained.
