I am filing a safety complaint regarding my 2012 Kia Rio, which currently has approximately 150,000 miles. I first became aware of these problems at approximately 120,000 miles. The vehicle has excessive oil consumption despite being consistently and properly maintained. I have been meticulous about maintenance because the vehicle has a lifetime powertrain warranty, and I have documentation and receipts for required maintenance, including regular oil changes and other scheduled services. On multiple occasions, I have taken the vehicle in for a scheduled oil change and discovered that it had little or no oil remaining. Because of this, I have had to begin having oil added between regularly scheduled oil changes. I do not know the exact amount of oil being consumed because I initially had no reason to monitor or measure oil consumption between oil changes. The vehicle also has a recurring catalytic-converter/check-engine warning that comes on, goes off, and later returns. It has experienced noticeable loss of power and has developed a clicking or knocking sound from the engine. When the vehicle is sitting or idling, it can also indicate that it is running hot even though it does not appear to actually be overheating. These problems have continued despite regular, documented maintenance. I am concerned about the safety implications of a vehicle consuming enough oil to have little or no oil remaining before its next scheduled oil change, particularly when there may be no consistent warning to alert the driver that the oil level is dangerously low. I am also concerned about the recurring catalytic-converter warning, loss of engine power, abnormal engine noise, and the possibility of engine or catalytic-converter failure while the vehicle is being driven. I understand that other Kia vehicles have been subject to recalls and investigations involving engine-related defects. I am asking the federal safety agency to review complaints involving the 2012 Kia Rio and investigate whether exces

Engine Fires
On March 29, 2019, the Office of Defects Investigation (ODI) opened two Preliminary Evaluations (PE19-003 on Hyundai and PE19-004 on Kia) to broadly investigate incidents of non-crash fires (regardless of origin or operational status of the vehicle) on various model year Hyundai and Kia vehicles. During the PE investigations, Hyundai and Kia issued several recalls to address vehicle fires, including those due to engine failures involving various engine types. The remedies for the engine failure recalls typically involve engine inspection (to detect existing damage), and if necessary, engine replacement. Additionally, both manufacturers have been installing an engine control software modification known as Knock Sensor Detection Software (KSDS) which is intended to detect impending engine failure, alert the driver, and limit engine power (to lessen likelihood of engine failure).KSDS is being installed under recalls and non-safety field actions, and both companies have extended limited engine warranties (see recall files). On December 22, 2021, ODI upgraded PE19-003 and PE19-004 to this Engineering Analysis (EA21-003, covering both Hyundai and Kia) to evaluate the scope of the prior recalls related to engine failures/fires and the efficacy of the recall remedies for the recalls, as well as the long-term viability of related programs and non-safety field actions being conducted by Hyundai and Kia. The former issue involved approximately 550,000 MY 2013 Hyundai Elantra, MY 2011 Kia Sorento, and MY 2012-2015 Kia Rio. The latter issue involved approximately 2.5 million recalled vehicles, which have been identified as displaying potential remedy concerns: Hyundai recalls 15V‑568, 17V‑226, 20V‑746, and 21V‑727; and Kia recalls 17V‑224, 19V‑120, 20V‑750, and 21V‑844. Regarding the recall scope issue, among all of the scope vehicles identified at EA opening, ODI found only the MY 2011 Kia Sorento vehicles equipped with both the Theta II 2.4L 4-cylinder Multi-Point Injection (MPI) and the Lambda II 3.5L 6-cylinder MPI engines experienced relatively high rates of reported fires. In December 2023, Kia issued recall 23V‑877 that will cover about 80,000 MY 2011 Kia Sorento vehicles equipped with the Theta II 2.4L MPI engines.  The remedy will involve an inspection, and if necessary, a replacement of the engine, as well as the installation of KSDS.  It should be noted that in 2021 these vehicles were included in a KSDS product improvement campaign with warranty extension. For the MY 2011 Sorento vehicles equipped with the Lambda II 3.5L engines, ODI believes that future engine failures/fires involving these vehicles will likely be due to a lax in adhering to the proper or scheduled engine maintenance (regular engine oil changes), rather than a design or manufacturing engine issue. Regarding the issue of the efficacy of the recall remedies, ODI found the majority of the recalled Hyundai and Kia vehicles, by model, experienced lower reported fire rates after the remedies were applied. Furthermore, ODI found that for most vehicles that did not receive the recall remedies, by model, experienced relatively high fire rates. To address this problem, Hyundai informed ODI in December 2023, that it will renotify all of its owners covered by the Hyundai recalls of engine failures/fires every 8 months for the next 3 years. In December 2023, Kia stated that it will renotify the majority of its owners every 8 months for the next 3 years.Several previously recalled Kia models are excluded from the renotification due to their lower reported rates of engine fires. Overall, the renotification actions will help to increase the recall completion rates, thus reduce the frequency of engine fires in the future. In view of the recall action being taken by Kia and renotification actions being taken by both Kia and Hyundai, ODI is closing this Engineering Analysis. Also, both companies have been released from the 2020-iniated Consent Orders (Kia since November 2022 and Hyundai since November 2023). The agency reserves the right to take additional action if warranted by future circumstances. To review the reports cited in the Closing Resume ODI Report Identification Number document, go to

What 2012 Kia Rio owners say
Most recent owner complaints, unedited.
Waiting to get air in my tire. Car was turned off and the car started fire under the hood.
I brought my Kia in for a recall, and they determined the part was discontinued thus making my vehicle inoperable. When I brought my vehicle in, it was driveable-now I have been without my vehicle for over a month.
The GDI 1.6L engines are manufactured with a flaw that affects piston rings and makes oil consumption go up which in turn can make the engine run dry and damage the engine, which if you're in a bad location could be dangerous. My car has been dealing with the issue and I searched yet found no recalls for the engine. 2. It can put me and others at risk, if my car breaks and I'm driving in a snowy or hot area, or breaks when driving up hill or down hill. 3. Look all over the internet GDI 1.6 Oil consumption issue. 4. Yes, repair shop. 5. Plenty of times barely drove 200 miles and I get the red lamp for no oil/low oil level.
Car started running oddly pulled over went to restart and Fire came up an engine compartment
The contact owns a 2012 Kia Rio. The contact stated that after the niece had park and exited the vehicle smoke and flames were present coming from under the hood of the vehicle. The fire department was called to scene to extinguish the flames. During the incident the vehicle was destroyed and towed away. The cause of the failure was not determined. The contact indicated that prior to the incident the vehicle was experiencing excessive oil consumption but no assistance was offered from local dealer. The manufacturer was not notified of the failure. The failure mileage was 108,000.
Check engine light comes on. I pull the code of p050a. I looked that up and there is a Techincal Service Bulletin, from Kia on this problem of Cold start idle air control system performance. Kia only put out a recall on the Kia Soul and not the Kia Rio. They have the exact same engine and computer with the 1.6L. The bulletin list both vehicle but the recall is only for the 1 vehicle. I was told by Kia dealer sorry to fix this I would have to pay to reprogram the computer. Kia originally was replacing the throttle body on the engine than decided because of cost, to reprogram the computer.
Will not start early morning, use about 3 quart oil a week, before warranty ran out Kia dealer check out and said to drive it another 900 miles, which made no sense, and bring back in Then they said it was out of warranty, what a scam Kia dealership is.they had overfill oil level 3 times before this problem
2012 kia rio, not currently subject to any recall, and having been maintained correctly, is experiencing dangerous levels of oil consumption. Current milage 108,000. Two weeks ago I sent the attached letter via case to kia consumer customer affairs seeking safety advice from the company relating to the issue. Kia never responded, opting to close the case without a word regarding the issue. Oil consumption is very high, and effecting engine performance. I assume the only recourse is to have the engine taken apart and examined, a costly review, however due to lack of response from kia I haven't yet; I was hoping they could coordinate through either a dealer or 3rd party investigator. Currently the car is not being used, as this anomalous issue is a concern for safety when driving. Considering the recent recall, as well as how the symptoms align with previously recorded issues to similar engines, I wished to create this report, if only to add my case to the federal safety agency's accounts. Thank you for your time joseph elliott
I recently purchased my vehicle and immediately noticed what seems to be oil coming from the engine, pooling on top of the block but also leaking onto the ground after being parked for an hour or so. The walls around the engine, mainly on the left side or passenger side were saturated with presumably the same fluid. Under the car is also saturated from what I am guessing to be a leak, perhaps the same leak from atop the engine block. I've had the car repaired and paid for a system fault diagnostic, and in both cases haven't received any helpful info as to what it is, the cause or where the leak is coming from, or how to treat it. I very recently had the oil changed and the invoice showed a comment stating that my car appears to be leaking oil. There was no further commentary. I fear that my kia rio may be dangerous to drive for reasons such as a fire hazard or breakdown from overheating possibly resulting in leaving me on the side of a highway, stranded. Also the A/C and heater do not operate as they should. The panel controls are out of whack and neither A/C or heat perform in sync with the commands. A mechanic has said this appears to be due to electrical issues, possibly with the main computer, though the systems fault diagnostics was performed after the mechanic informed me of this, and seeing that I was charged for that service I can only assume that the main computer is doing what it is meant to do, relaying the info to the tech's computer. I just don't know if I have a good car that needs a lot of work or if I'm driving a deathtrap. No recalls for this vehicle but I see a lot of kia's vehicles being recalled. And I believe they no longer make the kia rio. Just at a loss as to what is happening and what to do about it. Times are tough financially or I would definitely have more proper detailed info to give, that or have a good running car...
