2016 Kia Rio: excessive oil consumption

Filed Nov 22, 2025 · Engine · NC

My car is experiencing excessive oil consumption. Upon inspection, it was determined that the issue lies with my catalytic converter. I have discovered that this problem has been reported in other Kia vehicles. The information I found suggests that the oil I am using is being bypassed by the catalytic converter, which indicates a potential issue with the Kia car’s design. Engine light won’t go off

This vehicle is burning oil at an alarming rate: at least 1 quart per tank of gas, approximately 340 miles. No oil light comes on in the dash, even if the engine gets ran to dry. Kia accepts this and claims the vehicle is fine. Even with extended warranty coverage, I’m on month 8 now of trying to get this car fixed with Kia shops and now the catalytic converter is failing. Finally the car has displayed its first check engine code.

I stayed on top of oil changes and engine continued to burn an excessive amount of oil in between oil changes. No leak was found after having 3 different inspections. I was told this is a common problem with Kia engines from multiple Kia owners, mechanics, and oil change technicians. Despite this, I made sure I always had oil in it and kept up with the changes. Suddenly, while driving on the interstate, the engine completely failed. I had it towed to a mechanic where it was determined internal engine failure if some sort. My car only had 83,000 miles on it when this happened. Due to me being the second owner, ( I bought the cat at 14,000 miles) I was unable to receive the 100,000 miles power train warranty. I called my local Kia dealership to see if there was anything they could do and was told “engines fail all the time” and that there is nothing they can do.Replacing the engine is more than the car is worth. For the engine to fail out of nowhere with no warning (this was the first time any sort of light came on my dash) after spending time and money on upkeep, is unacceptable. It is also completely unsafe. After some researching, I see that this is a very common issue with kia engines and Kia failed to notify me about obsessive oil consumption and the their faulty motors. Over $400 dollars in mechanic fees and over $300 in towing fees to determine all of this and I am out of a car. Getting a new engine or even fixing whatever internal component it is would be way more than what my car is worth with it running.

Was told that my car was consuming too much oil and I’ve been doing oil consumption test for the past year I even did the chemical that was run through my motor which I had to pay for and it was over $800 I feel like they’re giving me the runaround one of the employees at Dick Hanna Kia also told me at one point that I could actually replace the motor myself but my car is still under warranty at 92,000 miles. I just want it resolved either they replaced my motor or do something I have two more oil consumption test and then at that point they will send the information to Dick Hanna Kia dealerships or wherever they send it and then tell me what to do next actually getting frustrated. I have to go every 1000 miles and it takes time out of my day to do this.

At first I thought I was leaking oil. on my next oil change I asked them about the oil consumption. they had me do an oil consumption study. this was around 95,000 miles. at my next oil change they suggested I talked with Kia. before my next oil change my car shut down while my mom was driving on the highway. and I had it towed to kia to find that the catalytic converter was clogged and need to be replace. whats worse is the Kia soul with the 1.6 engine has the exact same problem but that has a recall for it. but not the Rio.

At about 90000 mile brought car into dealership because it was consuming oil. Was told there was no leak found. Oil consumption was not covered. At about 110,000 miles had to bring car into shop because catalytic converter ended up being blocked and had to replaced. Less than a year later at 129,000 miles had vehicle towed back to shop again. Mechanic stated lower bearing had failed and engine would need to be replaced. Contacted junkyards for replacement and there were two he found but we're very expensive. He called Kia and they don't make that engine any longer. Guessing because of all the problems they have with it.
