The contact owned a 2015 Kia Rio. The contact stated that while the friend was driving approximately 70 MPH, the vehicle suddenly began to lose automotive power, and smoke was seen coming from under the hood. The vehicle was parked and the friend exited the vehicle and discovered flames coming from the engine compartment. The fire department was called to the scene and extinguished the flames. The vehicle was destroyed and later towed away to a nearby towing facility. A fire and police report was taken at the scene. The cause of the failure and fire was not determined. The manufacturer and local dealer were not contacted. The failure mileage was 118,000.
Engine making noise and smelling like it’s burning. Towed to mechanic said oil was not there despite recent oil change and said sparks of metal was on oil dipstick. Now being told needs new engine after recall oiece completed and the car has less than 110k miles. Kia will not honor an engine replacement.
The contact owns a 2015 Kia Rio. The contact stated that while driving at an undisclosed speed, the check engine warning light was illuminated. The vehicle was taken to an independent mechanic, who diagnosed a failure with the catalytic converter. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 53,000.
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.
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.?
Burning excessive oil, rod bearing noise
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. The vehicle was repaired but the failure persisted. The manufacturer was not notified of the failure. The failure mileage was unknown.
The contact owns a 2015 Kia Rio. The contact stated while driving 55 MPH, the vehicle started jerking and the contact smelled an oil burning odor coming from the vehicle.

The mechanic stated that the engine was misfiring, and that the engine needed to be replaced. The contact was referred to the dealer for assistance. The vehicle was towed to the dealer and the dealer confirmed the misfire and stated that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was not contacted.

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!
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.

SUDDENLY, THERE WAS A LOUD EXPLOSION UNDER THE HOOD AND THE CONTACT'S HEAD IMPACTED THE STEERING WHEEL. THE VEHICLE BECAME ENGULFED WITH BLACK SMOKE.

THE VIN WAS UNKNOWN.
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.
MY ENGINE CAUGHT ON FIRE AS I WAS DRIVING THE CAR. THERE WAS A KNOCK SENSOR ERROR DISCOVERED A COUPLE HOURS BEFORE, BUT NOTHING WAS INDICATING THAT THERE WAS IMMINENT CRITICAL DANGER.
DRIVING APPROXIMATELY 40 MPH, CAR HESITATES TO ACCELERATE. CHECK ENGINE LIGHT CAME ON. HAD CAR CHECKED, DIAGNOSTIC SAYS CATALYTIC CONVERTER IS NOT OPERATING PROPERLY. I HAD THIS PART REPLACED LESS THAN 4 MONTHS AGO! NOW THE SAME PROBLEM IS OCCURRING AGAIN!
I SENT IN A COMPLAINT ABOUT MY VEHICLE .I WROTE THE WRONG PROBLEM RIGHT PROBLEM IS CATALYTIC CONVERTER
WHEN I FRIST GOT MY CAR THE ENGINE LIGHT CAME ON. DEAN MCCRARY FIXED IT. NOW THE LIGHT COMES BACK ON AND OFF. MAY CAR DRIVE SLOW SOMETIME. I HAD IT CHECKED THEY SAID IT WAS CAVALIER
WHILE DRIVING THE VEHICLE AND ACCELERATING THE VEHICLE STALLS OUT.
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.
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.
PURCHASED THE CAR FROM KIA DEALER ON 5/20/17 WITH LIMITED POWER TRAIN WARRANTY. HAD OIL CHANGE DONE ON 7/22/17AND AGAIN ON 10/14/17(COPIES WERE PROVIDED TO THE WARRANTY COMPANY). THE SECOND ONE WAS AT THE DEALER. ON 12/8/17 MY DAUGHTER WAS DRIVING DOWN THE STREET AND FELT A JOLT AND SAW SMOKE COMING FROM THE HOOD OF THE CAR. SHE WAS ABLE TO PULL OVER AND GET OUT OF THE CAR SAFELY. SOMEONE USED A FIRE EXTINGUISHER TO PUT OUT THE FIRE BEFORE THE FIRE DEPARTMENT ARRIVED. IT WAS TOWED TO A DIFFERENT KIA DEALERSHIP WHO SAID "THE ENGINE HAS INTERNAL DAMAGE THAT LOCKED UP THE ENGINE AND CAUSED OIL TO SPILL AND CATCH FIRE." THE WARRANTY COMPANY DENIED THE CLAIM AND SAID THAT IT WAS LACK OF MAINTENANCE AND THERE WASN'T ANY OIL IN THE CAR WHICH CONTRADICTS WHAT THE DEALER SAID. WE TRIED FIGHTING IT BUT AFTER A MONTH WE NEEDED TRANSPORTATION AND REPORTED THE CLAIM TO OUR INSURANCE COMPANY WHO TOTALED THE CAR BUT DID NOT GIVE US FULL VALUE BECAUSE THE WARRANTY COMPANY SAID IT WAS LACK OF MAINTENANCE. NOW WE SEE ALL THE REPORTS ON OTHER KIA'S GOING ON FIRE AND BELIEVE OUR CAR HAD THE SAME ISSUE. WE LOST OVER $7,000 ON THE DEAL.
