What owners say about the engine
Verbatim from NHTSA complaints, newest first
“While driving at highway speeds, the vehicle suddenly began bucking, lost power, and lost oil. The engine compartment immediately caught fire. The fire was entirely non-collision related and required immediate extinguishing. The incident was logged by the Washington State Patrol. The vehicle was towed and subsequently inspected by a certified Kia dealership. The Kia dealership technicians officially diagnosed the cause of the fire as a catastrophic internal engine failure, specifically noting in writing that they "found hole in engine block." They noted there was no other possible causation. This spontaneous engine failure and resulting fire occurred at approximately 99,000 miles. The vehicle is currently disabled and available for inspection upon request.”
“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”
“My car is consuming a lot of oil and I have to add it on a weekly basis. The catalytic converter has already been replace once and is on the verge of having to be replaced again because of this issue. I just bought the vehicle last year. I see that there was a previous campaign with this same issue. See campaign NHTSA ID: 23V-652000. I am wondering why my vehicle was not part of it. Please advise next steps to remedy this safety issue on the 2018 KIA Rio models.”
“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.”
“Vehicle burning through excessive amounts of oil. Check engine light came on and car was making a loud ticking noise and knock. Dealership confirmed the vehicle will need a new engine. Kia Corporate denied replacement because vehicle is out of warranty. Reported problem to Kia before warranty expired and was still denied.”
“What component or system failed or malfunctioned, and is it available for inspection upon request? Complete engine lockup during operation at speed which caused steering and braking to be greatly hampered. How was your safety or the safety of others put at risk? The engine failed on a 4-lane highway in traffic which could have easily caused a high-speed accident since the car extremely decelerated and lost power steering and braking in order to get out of traffic. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes confirmed by an independent service center which told me it was either a cylinder rod or a lower engine bearing failure. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No, the manufacture KIA has a recall on other models in this year range but not the RIO. The other models have a similar engine failure caused by a faulty cylinder rod bearing. The RIO has never been added to this recall list, but it should be because it looks like the engine issues are also on this model in the same time frame. Were there any warning lamps, messages or other symptoms…”
