2018 Kia Rio: excessive oil consumption

Filed Aug 5, 2026 · Airbags, Electrical · FL

The Components that have malfunctioned are the airbags, exaust system, electrical systems, sensors, gaskets, and a few other things. We had 5 failed clockspring repairs. The first (3?) under warranty, we paid for another when they said it was our fault, then that mechanic said that it needed to go back to a dealership because it was defective. I advocated for months for it to be evaluated. No one at kia helped me despite this being a repeat warranty issue. I finally found a shop that would waive a diagnostic and he confirmed the issues atleast with the airbags- however in order to fully diagnose the engine they also needed to replace parts in order to perform an oil consumption test. While the represenative did approve the repairs for the airbag, they have not given the dealership an answear about ANYTHING engine related- we need an answear if we should be waiting or having it towed out of there. They have had it for a month. We repeatedly try to get ahold of them but they ignore when we call or email them. The represenative also made sexist comments about "being a woman" and its clear our safety concerns are not being handled serioursly. Just like with the inside, we get codes for certian parts but not all the other parts that go bad. You can not just hook it up to a computer and see what is wrong because of all the issues with the sensors (all reported under warranty and never fixed). The car goes through over 30 quarts of oil in between changes, and we belive that the tempterature sensors do not actually work because there is an EXCESSIVE amount of heat that comes off the engine. The clockspring turned into steering colums, a seat, electrical. Otherwise we can not drive the car anyways and would be happy to hand it over to be dismantled and inspected if the NHSTA would be willing to do that- the car is INCREDIBLY defective. I am INCREDIBLY scared if I have to drive off with this thing. Its an absolute safety hazzard weather or not the computer is flagging it.

Vehicle has excessive oil consumption defect acknowledged in Kia TSB ENG222. Repeated catalytic converter failures indicate potential overheating risk similar to 2019 Gamma engine recall for fire hazard. Engine burning oil creates risk of critically low oil levels leading to engine failure/stalling while driving. Multiple emission system failures (oil consumption, catalytic converter) suggest unsafe vehicle condition. Vehicle failed Kia’s own oil consumption tests in December 2023 and March 2024. Kia dealership recommended engine replacement per TSB ENG222 in March 2024. Kia denied coverage citing “second owner, out of warranty” despite defect clearly existing at time of purchase and being acknowledged in their TSB. Vehicle now showing catalytic converter failure code again (14-month-old converter failing). Kia refuses to remedy despite documented defect.

My 2018 Kia Rio is burning 2 quarts of oil every 800 miles, confirmed by a Kia dealership through an official oil consumption test. The issue first started around 110,000 miles and has progressively gotten worse. I have owned the vehicle since it had 40,000 miles, and I have always had the oil changed on time and maintained the car properly. Despite proper maintenance, the engine gives off a strong burning-oil odor, and smoke enters the cabin while driving. This happens consistently, not occasionally. Because the engine loses oil so quickly, it can run dangerously low without warning, creating a risk of sudden engine failure while driving. I regularly transport my [XXX] child, and the fumes entering the cabin are unsafe to breathe. Kia Customer Care denied goodwill assistance due to the number of previous owners and the mileage, even though the dealership confirmed abnormal oil consumption and noted this is a known issue with these engines. Kia has refused to assist repairing or replacing the engine, leaving me driving a vehicle that is unsafe and at risk of failure. The excessive oil consumption, smoke entering the cabin, and the potential for engine failure create a serious safety hazard for occupants and other drivers. I am requesting the federal safety agency to investigate this issue, as it appears to be a recurring safety-related problem with these engines.
