What causes the metal shavings in Hyundai / Kia Theta II engines?
Kia and Hyundai engines may show premature rod bearing failure. Once the bearings fail, the metal debris will contaminate the engine oil. Contaminated oil with metal shavings does further damage to the internal engine parts. As the oil circulates through the engine, it can cause excessive wear and damage to other areas of the engine such as lifters, clog oil galleries, and restrict oil circulation.
Symptoms of metal shavings in oil:
- Excessive oil consumption,
- Engine knocking
- Oil light comes on
- Engine Rattle
- Catastrophic engine failure
If you catch this problem early enough, you may be able to slow down the failure but eventually, a new engine or complete engine rebuild will be required.
What to do if you have this problem
If you have found metal shavings in your oil and your Kia or Hyundai is still under warranty you may be able to get your dealer to fix your car free of charge. Kia and Hyundai have issued a recall on over 1 million vehicles. Keep in mind that you will need to prove that you have performed regular oil changes and that the oil level was not low at the time of failure.
Which Hyundai / Kia vehicles are affected by this problem
Kia/Hyundai with either 2-liter or 2.4-liter gasoline engines have been identified with this problem. The U.S. engines were made at the Hyundai's engine plant in Alabama. The list of vehicles to be recalled in the U.S. includes:

How to check if you have metal in oil:
- Get an oil change.
- Drive your vehicle for 200 miles.
- Check the oil by pulling the dipstick.
- Place oil on a white cloth and check to see if there are any vsible metal shavings.
- You could also send your oil to a lab to perform oil analysis.
The bigger problem is that once the crankshaft bearings start to fail the metal shavings can block the oil passages and cause catastrophic engine failures.
Excessive rod bearing and crankshaft wear can cause poor engine lubrification.
As clearances in the bearings and crankshaft increase, your engine oil pressure starts to drop. To correct this problem you can install a high volume oil pump.
You can't eliminate factory defects, but there are a couple of things you can do to make your Hyundai / Kia engine last longer.
- If you recently noticed metal shavings in your engine oil perform a couple of oil changes right away. Do the second oil change after 50 miles.
- In the future, perform oil change more frequently. Your Kia and Hyundai dealer recommend 7500-mile oil changes. Our recommendation would be to complete oil change every 3000 miles.
- Use heavier weight oil allowed for your engine. For the Theta II engine, you can use oil with viscosity up to 5W40 motor oil.
Kia / Hyundai Theta II Engine Lawsuit
CTV News station covered Hyundai/Kia engine failure class action lawsuit. That coverage can be watched in the following video clip.
Hyundai Engine Oil Defect Class Action Lawsuit
Back in 2015, model year 2011, 2012 Sonatas were recalled over the chance of engine failure from limited oil flow to the bearings. Similar wear has been found in seized Kia engines. The affected Hyundai engines were assembled in the U.S. Complete details on this lawsuit can be found here.
Warranty Extension: Hyundai is extending the Powertrain Warranty for Class Vehicles. The extension of the warranty will cover the engine short block assembly consisting of the engine block, crankshaft and bearings, connecting rods and bearings, and pistons for 10 years and 120,000 miles (whichever comes first) from the original sale or lease of the vehicle. The 10-year / 120,000-mile extension of the warranty continues even if the vehicle is sold.
In March 31, 2017 Kia recalled many vehicles equipped with 2.0 and 2.4 L engine.
