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 NHTSA to review complaints involving the 2012 Kia Rio and investigate whether exces

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.

The engine of my Kia Rio 2017 is the system that is failing it is sudden with no warning and has been diagnosed by Kia themselves stating that the engine will seize. My safety is put at risk because the car may seize while in traffic causing difficulty steering and breaking. This problem was first confirmed by an independent shop called Accurate transmission (1040 s Joliet st, Aurora CO, 80013 or call 3033646254) and following that I took it to Kia for a diagnostic where they confirmed what Accurate transmission stated. This vehicle has not been inspected by anyone currently. There were no warning lamps previous to current issue. Warning lights appeared upon incident.

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.

As my car was driving my vehicle encountered sudden changes and my engine light went on. As the vehicle stopped driving on its own there was smoke coming from the hood and a fire stared shortly after underneath the car.

I was driving my 2017 Kia Rio at approximately 70 mph when the vehicle began shaking violently. I heard a loud mechanical sound from the engine compartment that sounded like something broke loose and was being thrown around. I immediately began pulling over as smoke started entering the cabin. As soon as I stopped, the car erupted into a fast-moving, intense fire originating in the engine compartment. The fire spread so quickly that the front of the vehicle and the passenger cabin were completely destroyed before the fire department arrived. The Austin Fire Department responded (Incident Type: Engine 2f) and the Travis County Sheriff's Office also opened a case (Case #[Insert Your Sheriff Case Number]). Multiple bystanders also called 911 due to the severity of the fire. The vehicle had under 80,000 miles and was maintained with regular oil changes every 6 months. I believe this fire was caused by a known manufacturing defect related to the engine connecting rod bearings or the HECU electrical short, both of which are subjects of major Kia safety recalls/settlements. The vehicle is currently a total loss
NHTSA complaint #11727456 — an unverified report by a vehicle owner.
The first problem part is the airbag. The clockspring was fixed twice under warranty. Then the dealership said they wont keep doing it and blamed me wrongly. I had a private mechanic repair the same part twice due to the code it was giving but it turns out thats not what's wrong with it. The entire airbag and electrical components are bad, that is why the two repairs the dealership as well as the private mechanic made did not work. We also have some engine problems they wont continue to fix because my warranty is now surpassed. The car burns through 20 quarts of oil in between changes, it has no leaks. It has so much carbon buildup. They replaced a gasket and thats another part that has continually needed replaced but they did not fix the issue that has caused it to go bad. When the small mechanics hear about the issue they are confused because the type of motor I have was recalled in other cars for the same issues. My car just recently surpassed the warranty, I should not be having to still fight the dealership to have a car in working condition for the same problems they kept putting bandaid on during warranty repairs.

I am filing this complaint regarding Kia America's arbitrary denial of coverage for a suspected connecting-rod-bearing failure in my 2014 Kia Rio (85,000 miles). The vehicle exhibits classic symptoms of the Gamma 1.6L GDI defect: excessive oil consumption (bone-dry after ~1,200 miles post-January 2026 shop oil change), flashing CEL, and loud rod knock after oil starvation. Kia corporate denied all extended warranty/campaign relief on 03/18/2025, stating the powertrain warranty expired in 2019 and "no campaigns" apply. This is inconsistent and deceptive: -U.S. Litigation: Early complaints and law-firm summaries in In re: Hyundai and Kia Engine Litigation II (C.D. Cal., 8:18-cv-02223) and related MDL explicitly referenced 2012–2019 Kia Rios with 1.6L Gamma GDI for the exact defect (oil burn → bearing failure → seizure/fire risk). However, Kia negotiated to exclude Rios from the final E2 Class Vehicles list (see kiaengineclasssettlement.com FAQ #6), limiting relief to Souls and select others despite the identical engine family. -Canadian Precedent: The McKenzie Lake/Strosberg class action explicitly includes 2012–2017 Kia Rios with Gamma 1.6 GDI for the same issues, providing inspections/repairs—proving the defect transcends model badging. -Safety & Consumer Impact: This selective denial violates Magnuson-Moss (unreasonable warranty conditions) and constitutes deceptive trade practices, as Kia advertised these engines as reliable while knowing the failure mode. I request: immediate investigation, compelled goodwill repair (or full engine replacement), and documentation of how Kia limited Rio coverage in settlement negotiations. Attached are all supporting records.

On the morning of October 15th, the oil light of my 2019 Kia Rio came on, immediately followed by extreme engine noise, just before the engine locked. I had the vehicle towed to a nearby service center. They checked and reported that all oil had leaked out and motor had locked. I then had vehicle towed to Kia dealer and requested a motor replacement. They not only charged me for a diagnostic test that determined the motor had locked but also refused to replace the engine without me paying $12,000. The vehicle's motor has the same problems as the motors in 2011-2019 kia Engine Defect Settlement but for some reason was allowed to be excluded from the settlement.
NHTSA complaint #11710569 — an unverified report by a vehicle owner.
The engine experienced a rod bearing failure resulting in internal engine damage and sudden loss of normal engine operation. The vehicle and failed engine components are currently available for inspection upon request. The engine failure occurred while the vehicle was traveling at high speed on the freeway, resulting in sudden loss of engine power. This created a significant safety risk, as loss of power at freeway speeds increases the likelihood of collision with surrounding vehicles and posed a danger to myself and other motorists. The failure was diagnosed and confirmed by a Kia dealership as rod bearing failure. The vehicle has been inspected by a Kia dealership. No inspection has been conducted by police or insurance representatives. There were no prior warning lamps, messages, or indications of engine malfunction before the failure. The only warning light present prior to the incident was the check engine light related to previous vandalism involving an attempted catalytic converter theft, which caused ongoing sensor issues unrelated to engine performance. That warning light had been present despite resets during routine maintenance and was not associated with any engine functionality issues. There were no pre existing engine performance problems, drivability issues, or warnings indicating impending failure. The engine failure was sudden and catastrophic. This failure is consistent with known Kia engine rod bearing defects that have resulted in recalls, safety campaigns, and settlements. Kia has denied assistance in this case, stating that my VIN is excluded due to manufacturing origin, despite the identical failure mode

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.

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
NHTSA complaint #11700990 — an unverified report by a vehicle owner.
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 NHTSA to investigate this issue, as it appears to be a recurring safety-related problem with these engines.

The contact owns a 2013 Kia Rio. The contact had notification of NHTSA Campaign Number: 23V652000 (Service Brakes, Hydraulic) and the vehicle was taken to the dealer for the recall repair. The recall repair was performed; however, while starting the vehicle the check engine, ABS, and oil warning lights and several other unknown warning lights illuminated. While attempting to turn the steering wheel, there was a lot of resistance in the steering wheel and while pressing the brake pedal the brake pedal went to the floorboard and lost power brakes functionality. The contact checked the brake fluid level, and the vehicle was returned to the dealer. The contact was informed that there repair had not worked, and resetting the fuse had failed. The vehicle was not repaired and remained at the dealer. The manufacturer was made aware of the failure and opened a case. The failure mileage was approximately 114,928.

2018 Kia Rio – severe oil consumption leading to low compression (30 PSI on Cylinder 2) and engine failure. Dealership installed incorrect non-OEM spark plugs prior to failure. Kia denies warranty coverage although this matches known engine defects in other Kia models
NHTSA complaint #11692892 — an unverified report by a vehicle owner.
My 2018 Kia Rio S (VIN [XXX] ) suffered sudden engine failure at approximately 84 000 miles. I pulled over immediately when the oil light came on, but the engine began rattling and was later diagnosed by the dealer as a bearing/seizure failure requiring full engine replacement (estimate ≈ $15 865). This vehicle uses the 1.6 L Gamma II GDI engine, which is the same engine family already included in Kia’s “Engine Litigation II” settlement and KSDS (Knock Sensor Detection System) program for Forte, Soul, and other models. However, Kia claims the 2018 Rio is not covered by the extended warranty even though the failure mode is identical (rod-bearing wear and oil starvation). I never received any recall or settlement notice. The lack of notification and exclusion of the Rio model leave owners unprotected against a known safety-related defect that can cause stalling or fire. I request NHTSA investigate inclusion of 2018 Kia Rio vehicles in the existing Gamma engine recall/settlement.

The contact owns a 2016 Kia Rio. The contact stated that upon driving from a complete stop, the vehicle failed to exceed 2-3 MPH. There was no warning light illuminated. The contact was able to drive to the residence. The Ford dealer where the vehicle was purchased arranged for the vehicle to be picked up at the residence. The Ford dealer informed the contact that the mechanic and the Kia dealer where the vehicle was taken could not determine the cause of the failure. The contact then took the vehicle to an independent mechanic, where it was determined that the catalytic converter was clogged and needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 126,000.
