Hyundai Kia Metal shaving in Oil (Theta II Engine)
Many Hyundai and Kia cars equipped with Theta II (2.0 L turbo and 2.4 L) engines may notice metal shavings in their engine oil. This article will provide details about this problem. Check if your oil has metal shavings and what to do if you find them.
Engine failures are reported to occur as early as 30,000 miles. These symptoms affect US vehicles and maybe a common problem experienced by Kia / Hyundai owners worldwide. If you have this problem, please use the comments section to let us know.
Kia and Hyundai engines equipped with the Theta II engine 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 engine areas, such as lifters, clog oil galleries, and restrict oil circulation.
Symptoms
- Excessive oil consumption
- Engine knocking
- The oil light comes on
- Engine Rattle
- Catastrophic engine failure
What to do
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 of over 1 million vehicles. Remember that you must prove that you have performed regular oil changes and that the oil level was not low at the time of failure.Affected models
Kia/Hyundai vehicles with either 2-liter or 2.4-liter gasoline engines have been identified with this problem. The U.S. engines were made at Hyundai’s engine plant in Alabama. The list of vehicles to be recalled in the U.S. includes:- Hyundai Santa Fe Sport SUVs, 2013 – 2014

How to check

Hi I have a 2020 Hyundai Santa Fe with 60k miles and when I changed the oil I found metal flakes in it. I took it to the dealer and all they said is this normal and to monitor it. They didn’t even drain the oil to see if there was more in the oil. They just pulled the dipstick. This can’t be normal. I contacted Hyundai customer care and they stated it doesn’t seem right but the dealerships hold the warranty and there is nothing they can do unless the deal determines it is not right . Not sure how to get them to correct whatever is going on in the engine. It is still under warranty.
This just happened in my 2007 sonata. Have you heard of similar issues in 2007s?
In your write up you mentioned that one of the ways to manage the problem is to “install a high pressure oil pump”. However you failed to give an example of one that is compatible and will work. Can you let me know ?
