All Hyundai i30 faults28 documented faults on this model

What you are looking at

No photograph available

We do not hold a verified photograph for this fault yet. We would rather show none than show a picture of something else.

What goes wrong

Piston ring flutter on 1.4L Gamma (G4FA) and 1.6L Gamma (G4FC/G4FG) engines causes oil to enter the combustion chamber and burn during normal driving. Consumption rates of 1L per 1,000km or worse are widely reported. Hyundai acknowledged the issue with a warranty extension programme in several markets. NZ and AU owners reported out-of-pocket engine repairs after extended warranty eligibility was denied based on service record gaps or mileage thresholds.

What you would notice

Blue or grey smoke from exhaust on cold start or acceleration
Oil level below minimum before next service is due
Burning oil smell during and after driving
Fouled spark plugs with oily carbon buildup
Engine oil warning light activating well before service mileage

How to check it

Where to look. Engine internals - piston rings, cylinder walls and valve stem seals

Check dipstick level and ask to see the last service invoice for recorded oil level notation.
Cold-start and observe exhaust for blue smoke.
Inspect spark plugs for oil fouling.
Request any dealer consumption test records or warranty extension correspondence.
Verify oil change intervals are within manufacturer specification.

What it costs to put right

$1,200 to $6,500 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

Ask the seller

“How frequently do you top up the engine oil between services?”
“Has the car been through a Hyundai oil consumption test?”
“Did Hyundai offer or carry out any warranty repair for oil consumption?”
“Has the engine ever needed top-up oil between 5,000km service intervals?”

Everything above is true of the model, and it is free. What it does not tell you is whether THIS car has been looked after: its odometer history and whether the reading has ever gone backwards, whether there is still money owing on it, whether it has been reported stolen, how many owners it has had and what it is really worth today.

Hyundai i30 buyer questions

Is gamma engine excessive oil consumption serious on a Hyundai i30?

We rate it major and very common on the Hyundai i30. Piston ring flutter on 1.4L Gamma (G4FA) and 1.6L Gamma (G4FC/G4FG) engines causes oil to enter the combustion chamber and burn during normal driving. Consumption rates of 1L per 1,000km or worse are widely reported. Hyundai acknowledged the issue with a warranty extension programme in several markets. NZ and AU owners reported out-of-pocket engine repairs after extended warranty eligibility was denied based on service record gaps or mileage thresholds.

How much does it cost to fix on a Hyundai i30?

$1,200 to $6,500 at New Zealand independent workshop rates. That figure is for this job on its own. A car showing the symptoms on this page is usually worth either walking away from or negotiating down by at least the repair figure.

Which Hyundai i30 years are affected?

Our research records this fault on the 2011–2017 Hyundai i30. Build dates move around, especially on imported cars, so treat the range as the years to look hardest at rather than a guarantee either way. The official records tell you the exact build and first registration date for the car in front of you.

How do I check for it before I buy?

Check dipstick level and ask to see the last service invoice for recorded oil level notation. Cold-start and observe exhaust for blue smoke. Inspect spark plugs for oil fouling. Request any dealer consumption test records or warranty extension correspondence. Verify oil change intervals are within manufacturer specification.
