Three issues: 1) Upon stepping on the gas from a stop, the car often takes 4 or more seconds to actually move. This more than once has gotten me almost hit in the back by the other cars. 2) The car often makes "tractor noises" that are extremely loud and annoying. 3) The mechanic at the shop I took it to said that there's a crazy amount of oil going though the exhaust system. This could result in hat accumulation in the engine and jam it up (at best) or actually lead to a spontaneous fire. I am afraid of getting stranded so I haven't been driving very much. The KIA dealership said that there's nothing they can do. are you kidding me?

WHILE DRIVING ON THE NJ TURNPIKE AT NIGHT TIME, I WENT TO CHANGE FROM THE RIGHT LANE INTO THE MIDDLE LANE AND THE CAR STALLED NOT ABLE TO PICK UP SPEED. AS THE CAR STALLED THERE WAS A FAST MOVING TRUCK WHICH WAS COMING AND THAT WAS ABLE TO SWITCH LANES FORCING ME TO MOVE INTO THE LAST LANE WHICH MADE THE CARS BEHIND ME HAVE TO COME TO A SUDDEN STOP. I THEN HAD TO PUT ON MY HAZARDS AND SLOWLY MOVE BACK OVER TO THE SHOULDER. ONCE COMPLETELY STOPPED I SHUT OFF THE ENGINE. AFTER WAITING FOR SOME TIME I STARTED THE CAR AGAIN, BUT NOTHING CHANGED. I REMAINED IN THE RIGHT LANE WITH HAZARDS ON AND DROVE THE CAR NOT BEING ABLE TO GO ABOVE 40 MPH. EVENTUALLY THE CAR GOT BACK TO DRIVING NORMAL RIGHT BEFORE ARRIVING HOME WHICH WAS ABOUT A 40 TO 50 MINUTE RIDE. THE CAR WAS TAKEN TO THE DEALERSHIP AND I LEARNED THAT THE CATALYTIC CONVERTER NEEDS TO BE REPLACED. THIS IS AFTER TAKING THIS CAR TO BE LOOKED AT TWICE AND BEING TOLD THAT THERE WAS NOTHING FOUND. NOW I FIND THAT THERE IS A RECALL ON THE CAR (NHTSA ID: 19V120000), BUT IT SAYS THAT MY VEHICLE IS NOT AMONGST THE VEHICLES RECALLED.

WHILE SITTING IN TRAFFIC MY CAR BEGAN TO SHAKE AND THEN STALLED AND TURNED OFF. IT WAS ABLE TO RESTART AND THEN LATER WHILE DRIVING DOWN THE INTERSTATE IT BEGAN TO STOP ACCELERATING WHEN I PRESSED THE GAS. FORTUNATELY I WAS ABLE TO MAKE IT TO THE SHOULDER FROM THE LEFT LANE AS CAR SLOWED TO A STOP AND THE BREAK PEDAL LOCKED UP. THE CAR WOULD NOT TURN ON ANY MORE. AFTER MECHANIC INSPECTION, THEY REPORTED THAT A PISTON HAD MELTED IN THE ENGINE AND BECAUSE THE OIL HAD DRIED UP, EVEN THOUGH THE CAR HAD ITS LAST OIL CHANGE TWO MONTHS AGO.

AFTER TAKING MY CAR INTO THE DEALERSHIP FOR A RECALL AND AN UPGRADE TO COMPUTER SOFTWARE, I WAS TRAVELING ON THE HIGHWAY AT 65 MPH AND LOST POWER TO THE ENGINE WHILE IN THE MIDDLE LANES OF TRAFFIC. I TOOK THE VEHICLE BACK TO THE DEALERSHIP, AND UPON THE COMPLETION OF AN INSPECTION, THEY SAID THE VEHICLE IS SAFE TO DRIVE AND POWER WAS RESTORED. I WAS NOT OFFERED A LOANER CAR, AND HAD TO WALK OR USE PUBLIC TRANSPORTATION FOR SEVERAL DAYS. I AM NOW EXPERIENCING THE SAME ISSUE AGAIN. I CANNOT TRAVEL OUT OF TOWN WITHOUT THE POSSIBILITY OF THE SAME THING HAPPENING AS A SAFETY MECHANISM TRIGGERS. I HAVE TO FIND MY OWN MEANS OF TRANSPORTATION AND ONLY TRAVEL LOCALLY. IF THIS HAPPENS AGAIN WHILE ON THE HIGHWAY WITH MORE TRAFFIC I COULD BE INVOLVED IN A VERY SERIOUS ACCIDENT. THEY HAVE ALSO NOT OFFERED ANY FORM OF COMPENSATION FOR MY TIME LOSS WITH MY VEHICLE. THIS IS VERY DIFFICULT TO DEAL WITH FROM DAY. WHEN THE SAFETY MECHANISM TRIGGERS, THE VEHICLE WILL BARELY DO 35-45 MPH. IT TAKES MORE THAN 15 SECONDS TO ATTAIN THAT SPEED WHICH IS NOT SAFE IN HEAVY TRAFFIC OR MODERATE TRAFFIC. THE CAR WILL START AS NORMAL; HOWEVER, WITH TRYING TO TAKEOFF THE VEHICLE WILL NOT ACCELERATE AS NORMAL. PRIOR TO THIS 'UPGRADE' THE VEHICLE NEVER HAD ISSUES WITH ACCELERATION.

Official recalls

19V120000 · Engine; Engine And Engine Cooling:exhaust System:emission Control:catalytic Convertor

Feb 22, 2019

Kia Motors America (Kia) is recalling certain 2012-2016 Kia Soul vehicles equipped with 1.6L Gasoline Direct Injection (GDI) engines. High exhaust gas temperatures may damage the catalytic converter, possibly resulting in abnormal engine combustion and damage to one or more of the engine's pistons and possible piston connecting rod failure.

Consequence & remedy

Consequence: Piston damage may result in an engine stall, increasing the risk of a crash. A broken connecting rod may puncture the engine block allowing engine oil to escape. The leaking oil may contact the exhaust, increasing the risk of a fire.

Remedy: Kia will notify owners, and dealers will upgrade the Catalytic Overheating Protection Engine Control Unit logic to prevent overheating of the catalytic converter. In addition, the catalytic converter will also be replaced if it has been damaged. Depending on the extent of any damage, the engine may also be replaced, free of charge. The recall began April 17, 2019. Owners may contact Kia customer service at 1-800-333-4542. Kia's number for this recall is SC176.

EA21003 · Engine Fires

Opened Dec 22, 2021 · Closed Feb 5, 2024

Status: closed (inferred from source dates) · Engine

On March 29, 2019, the Office of Defects Investigation (ODI) opened two Preliminary Evaluations (PE19-003 on Hyundai and PE19-004 on Kia) to broadly investigate incidents of non-crash fires (regardless of origin or operational status of the vehicle) on various model year Hyundai and Kia vehicles. During the PE investigations, Hyundai and Kia issued several recalls to address vehicle fires, including those due to engine failures involving various engine types. The remedies for the engine failure recalls typically involve engine inspection (to detect existing damage), and if necessary, engine replacement. Additionally, both manufacturers have been installing an engine control software modification known as Knock Sensor Detection Software (KSDS) which is intended to detect impending engine failure, alert the driver, and limit engine power (to lessen likelihood of engine failure).KSDS is being installed under recalls and non-safety field actions, and both companies have extended limited engine warranties (see recall files). On December 22, 2021, ODI upgraded PE19-003 and PE19-004 to this Engineering Analysis (EA21-003, covering both Hyundai and Kia) to evaluate the scope of the prior recalls related to engine failures/fires and the efficacy of the recall remedies for the recalls, as well as the long-term viability of related programs and non-safety field actions being conducted by Hyundai and Kia. The former issue involved approximately 550,000 MY 2013 Hyundai Elantra, MY 2011 Kia Sorento, and MY 2012-2015 Kia Rio. The latter issue involved approximately 2.5 million recalled vehicles, which have been identified as displaying potential remedy concerns: Hyundai recalls 15V-568, 17V-226, 20V-746, and 21V-727; and Kia recalls 17V-224, 19V-120, 20V-750, and 21V-844. Regarding the recall scope issue, among all of the scope vehicles identified at EA opening, ODI found only the MY 2011 Kia Sorento vehicles equipped with both the Theta II 2.4L 4-cylinder Multi-Point Injection (MPI) and the Lambda II 3.5L 6-cylinder MPI engines experienced relatively high rates of reported fires. In December 2023, Kia issued recall 23V-877 that will cover about 80,000 MY 2011 Kia Sorento vehicles equipped with the Theta II 2.4L MPI engines. The remedy will involve an inspection, and if necessary, a replacement of the engine, as well as the installation of KSDS. It should be noted that in 2021 these vehicles were included in a KSDS product improvement campaign with warranty extension. For the MY 2011 Sorento vehicles equipped with the Lambda II 3.5L engines, ODI believes that future engine failures/fires involving these vehicles will likely be due to a lax in adhering to the proper or scheduled engine maintenance (regular engine oil changes), rather than a design or manufacturing engine issue. Regarding the issue of the efficacy of the recall remedies, ODI found the majority of the recalled Hyundai and Kia vehicles, by model, experienced lower reported fire rates after the remedies were applied. Furthermore, ODI found that for most vehicles that did not receive the recall remedies, by model, experienced relatively high fire rates. To address this problem, Hyundai informed ODI in December 2023, that it will renotify all of its owners covered by the Hyundai recalls of engine failures/fires every 8 months for the next 3 years. In December 2023, Kia stated that it will renotify the majority of its owners every 8 months for the next 3 years.Several previously recalled Kia models are excluded from the renotification due to their lower reported rates of engine fires. Overall, the renotification actions will help to increase the recall completion rates, thus reduce the frequency of engine fires in the future. In view of the recall action being taken by Kia and renotification actions being taken by both Kia and Hyundai, ODI is closing this Engineering Analysis. Also, both companies have been released from the 2020-iniated Consent Orders (Kia since November 2022 and Hyundai since November 2023). The agency reserves the right to take additional action if warranted by future circumstances.
