Stalled out
While driving on the interstate highway the engine stopped. The circumstances surrounding the failure matched those for Kona VINs that were recalled.
My car consumes a lot of oil. This is a very similar problem as the wrong tempered piston rings. All this car has used is 5W 20 full synthetic oil., which gets changed every 5000 miles. I would burn around 1 quart every 1000 miles. Dealer solution is to put in 5W 30 full synthetic oil. Got a little better but within a few months, back to burning1 quart every 1000 miles. Dealer is now saying…
The piston went through the top of my engine with my entire family in the car. We managed to get to a mechanic. And bring it to the dealership. We are very lucky to be alive.

Common questions
How serious is the engine problem on the 2021 Hyundai Kona?
It's a documented issue but not catastrophic. 56 complaints have been filed. Repairs average $3,100 and most owners catch it before it causes a breakdown.
At what mileage does the engine typically fail?
Across the 18 complaints that reported odometer mileage, most engine failures cluster between 8,900 and 87,000 miles, with the median around 36,000. A quarter of owners report trouble before 8,900; a quarter make it past 87,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $3,100 for engine repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to engine?
No active recalls currently cover engine issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
