After two weeks of buying the car from a dealer, I was driving and I heard a noise in the engine, when I checked it had almost no motor oil. I have changed the oil and filter, but it consumes 2 quarts every 2 weeks (less than 1,000 miles). This has been happening since April 2021.

Last night, my car ran exactly as usual. No warning lights on the dash. No strange sounds. This morning when I started the car, there was a weird ticking sound coming from the engine. I decided to take the car into the shop. About a mile from home, it began to have trouble with acceleration and would randomly stall for a fraction of a second before catching again. The ticking sound became unbearable just as the check engine light and oil level lights turned on, so I pulled over and called a tow truck. After inspection at the auto shop, my beloved car was diagnosed with premature engine failure. The mechanic explained that this engine consumed oil rather than just using it to lubricate the moving parts, meaning that even religious oil changes are not enough. Had I continued driving instead of calling a tow, my car likely would have caught fire! Now I have no car (well a car but no engine) and because I am the second owner, the warranty doesn't apply to me. I have been a loyal Kia and Hyundai owner despite bad publicity over the years because I saw major improvements and innovative growth in the company. Kia tells me that because there is no active recall on the engine and I don't qualify for the warranty, there's nothing they can do. Please note they are actively involved in a lawsuit with the goal of recalling the 1.6L Gamma engines in Kia Rio 2015 for this very reason! There are a small percentage of defective engines that pose a fire risk in these cars. Raising awareness by contacting the company directly and reporting to NHTSA is the only way that Kia/Hyundai might do something about it!

I was driving to work, hand heard a pop under my hood. My engine and battery indicator lights started flashing and I lost all power. After polling over and turning my car off, I noticed a tone of smoke coming from under the hood. I popped the hood latch and peaked under with out opening the hood after seeing light. I noticed the flames and grabbed my phone to call 911. Soon after the car was engulfed inflames and 3 bangs where heard. Both tires and I'm guessing the fuel line erupted. The front half of my car was now ablaze starting to reach the interior started to burn before the fire department could put the fire out.

Rio

  • 70,000 miles
Vehicle was in motion turning right decelerating as I turned. Once I turned, acceleration pedal was disengaged and no acceleration was happening. Braking system was completely locked up and could not press the brakes. When I coasted to a stop, there was visible fire coming from underneath the engine compartment. Temp gage never registered as high while driving. Within a matter of a couple minutes, the whole car was engulfed in flames as I waited for the fire department to arrive. They said there was no visible fluid leaking on the ground and did not know the cause of the fire. Car was maintained regularly for oil. Had issues with the car overheating and took it to Kia and they could not find anything wrong with it and released me. Car is totaled now.

The engine light is constantly on but when hooked to the machine, there are no error messages. Some days it's on, some days it's not.

Rio

  • 11,000 miles
The engine periodically will stall for 2-3 seconds, usually when starting a left turn from a stop. This can prove hazardous in a busy intersection. This has been going on since I bought the car 12 October 2015. The dealer stated the "hesitation" was a normal function of the engine computer's "acclimation" to the driver. It hasn't adjusted to me, and I'm afraid to let my wife or daughter drive the car.
