My Kia had be under an unresolved recall that can cause a fire, not only putting myself and my family, but other drivers at risk. I have a toddler who rides with me and would be extremely hard to get out of a car seat if the car caught on fire, as such I have reduced driving with them to ensure safety, but this is an issue that cannot continue and I should not have to put myself and others at risk. I cannot afford to buy a new car and should not be forced to due to a manufacturing issue

The contact owns a 2015 Kia Rio. The contact stated while driving at approximately 40 MPH, the brake pedal was depressed, the steering wheel began shaking and the vehicle failed to slow down as intended. Additionally, when the accelerator pedal was depressed, the speed of the vehicle increased dramatically. The vehicle then stalled and was towed to an independent dealer where it was diagnosed that the oxygen sensor and air fuel ration sensor needed to be replaced.

My oil light does not and has not ever notified me of my oil level being low. The engine burns oil for unknown reasons. The oil dip stick tells me my oil is full after adding two quarts of oil but it-??s calls for 3.8 quarts of oil.?

My vehicle consumes oil according to my Midas repair shop. I was unaware that when I brought it in for regular servicing, the engine was almost empty of oil according to the mechanic. It had been rattling upon acceleration and lacking power set on ECO, but I ignored it. Now, I have to check and add 1/2 to 1 quart of oil every 7-10 days as the dipstick shows oil is low and also very dark. There is also an engine warning light on most of the time but it comes up as from the Catalytic Converter which I doubt. The electrical system also flashes on the dash where the a/c settings and circulation fan are on ocassion but is corrected when the temp guage is adjusted 1 click toward the warmer setting. I was notified of the lack of oil on my visit to Midas for an oli change back in April 2023. The mileage was 110,000 then. Everyone I know who has/had a Kia has had this problem and 3 have lost their engines as a result. Kia has lost my confidence because nothing was advised to owners until I found out of this common and costly issue just by chance. I wont buy another Kia now.

After an oil routine change last May, my mechanic informed me that the engine had almost no oil. I had been hearing a rattle when accelerating at times and noticed the vehicle seemed to be having trouble when increasing speeds were necessary (entering higher traffic areas/highway on ramps). I had always met the scheduled oil change requirements since I bought it in 2019 but this was the first time I had been told of this. The mechanic told me that it has been known that these vehicles have this problem. I usually went to the same reputable mechanic. Now, as requested by the mechanic, I check the oil each week and find that I have to add 1 quart every 10 days or less to keep the engine from failing outright. The engine light periodically comes on and goes off again, but I was told it was possibly related to the catalytic converter. I do not feel confident driving it much longer especially on highways because of possible engine failure on very hot summer days leaving me stranded in the heat.

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.

problem #4

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.

problem #2

Dec 212017

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.
