Kia Rio loss of power problems

Filed Oct 19, 2026 · Electrical, Engine · WA · fire

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.

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

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

The engine started to lose power, and the check engine light illuminated. The power drop was most noticable when accelerating from a stop. At times, randomly, the engine RPMs would dip down to 200-300 at idle and would almost stall. Upon further investigation, the engine has been excessively consuming oil. I brought the vehicle to a local mechanic shop to get a detailed diagnosis, they informed me the catalytic converter was clogged and constricting exhaust flow. The engine has developed a ticking/knock. The catalytic converter, and an O2 sensor was replaced with that visit. The ticking/knock persists.

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 of the problem prior to the failure, and when did they first appear? No, they only came on when the engine failed. Then every warning light appeared.

This vehicle has electrical issues none stop. One day it randomly stalled out while still in motion and lost all power. No power at all. It was “repaired” and I had it for 2 weeks and it again lost all power while in motion. It put my life completely at risk as I had to pull over into a parking lot after losing all power turning in the middle of a very busy main intersection. Kia dealership said it was the main wiring harness at first and replaced that but then the second time said that the new harness was out again and needed replaced a second time because of a fuse that was causing too much power therefor blowing the wiring harness again? Now I am having engine and electrical issues months later. I had what appeared to be a need for a tune up. Which was done. It has continued to throw wrong codes and lights come and go on the dash all the time. I’ve gotten several tests done and I always get a code stating misfiring even when there is no light on the dash. The check engine light will come on for 2 weeks then randomly go off for 2 weeks. No matter what it will throw a code as misfiring in the 1&3 cylinders. Spark plugs, coils, air filter. everything has been replaced yet the light still comes and goes and it continues to throw the code. Car has been seen by the dealership multiple times

On June 29, 2022, I was driving on I-5 southbound when I heard a loud sort of tapping sound coming from my engine. About 30 minutes later, before I had time to get to a gas station, there was a loud "BOOM!" sound and all of a sudden, the catalytic converter light and some other dash lights started to flash and I started to lose power. I pulled over to the left shoulder of the highway and before I could even pop the hood, I noticed flames immediately licking from the underside of the hood. I grabbed my phone and pulled my rabbit in her cage from the back seat of the car and called 911. My car continued to burn, starting a small brush fire, until the fire department finally came and put the fire out. The whole front of my car was completely incinerated and it had made its way to the back hatch in less than hour. I don't know for certain what caused this as the only indication of a problem was the loud tapping sound- zero dash lights were flashing until the boom. I had just taken the car in for an oil change and general check up less than a week before, and they saw nothing amiss. Geico, my insurance company, has inspected it to determine that it is, in fact, a total loss, but I'm sure they didn't do a sort of diagnostic to determine what happened to cause the incident. I am beyond lucky that I was able to escape my car with my pet and my life, but had the fire moved any faster through the car, we would be dead. It all happened within an hour.
