I WAS ON THE FREEWAY IN THE FAST LANE AND MY CAR STARTED ACTING LIKE IT WANTED TO STALL. THE ENGINE LIGHT CAME ON BRIEFLY AND WENT AWAY. I HIT THE GAS TO TRY TO GET OVER TO THE RIGHT LANE SO THAT I COULD EXIT THE FREEWAY AND NOTHING WAS HAPPENING WITH THE RPM IT WOULD NOT GO OVER 2 AND I THOUGHT I WAS GOING TO STALL ON THE FREEWAY. I WAS SO UPSET AND FINALLY MADE IT TO AN OFF RAMP. WHEN I STOPPED AT THE OFF RAMP THE CAR WAS SHAKING AND MAKING A TERRIBLE NOISE LIKE IT WAS GOING TO JUST EXPLODE. I CONTEMPLATED STAYING OFF THE FREEWAY AND TAKING THE STREETS BUT I WAS NOT IN A GOOD AREA SO I GOT BACK ON THE FREEWAY AND STAYED IN THE RIGHT HAND LANE TO EXIT AND HEAD STRAIGHT TO THE DEALERSHIP. I IMMEDIATELY CALLED THEM AND TOLD THEM WHAT HAPPENED TO ME. THEY SAID IT WAS A CYLINDER THAT WAS MISFIRING AND THAT THEY REPLACED IT. WELL I WAS DRIVING YESTERDAY AND THE ENGINE LIGHT CAME ON AGAIN AND MY CAR WANTED TO STALL AGAIN AND IT HAD ONLY BEEN A WEEK SINCE THEY SUPPOSEDLY FIXED IT. I TOOK THE CAR IN AND AGAIN THEY BLAMED IT ON THE OIL AND ARE NOW SAYING THAT MY ENGINE MAY BE BURNING THE OIL FASTER THAN IT SHOULD AND IF THAT IS THE CASE THEY WILL NEED TO REPLACE THE MOTOR. THE CAR HAS ME ON EDGE AS I DRIVE MY KIDS AND GRANDKIDS EVERYWHERE. I DO NOT FEEL SAFE IN THIS CAR AT ALL ANYOMRE. I FEEL LIKE THE ENGINE CAN GIVE OUT AT ANYTIME WITHOUT WARNING.

WHEN I CALLED THE DEALERSHIP ABOUT THE CODE THAT POPPED UP WHEN I USED MY READER TO READ THE CHECK ENGINE LIGHT THAT POPPED UP TWO DAYS BEFORE THANKSGIVING. IT SAID IT WAS THE CATALYTIC CONVERTER. THE KIA LADY TOOK MY VIN AND SAID THERE WAS NO RECALLS BUT EVERYONE WITH MY CAR WAS CALLING IN ABOUT IT. AND THE PART ITSELF IS 1200 DOLLARS. HOW MANY OTHERS HAVE TO GO THROUGH THE EXACT SAME THING WHICH ALSO SAYS IT CAN RESULT IN LOSS OF CONTROL. AS A MOTHER WITH A TODDLER WHO CHOSE THIS CAR BASED ON ITS AFFORDABILITY AND SAFETY FEATURES. THIS IS UNACCEPTABLE. THERE NEEDS TO BE AN ISSUE RECALLED IMMEDIATELY. THE CAR IS A 2016 KIA. THERES SHOULD BE NO REASON THAT I WOULD HAVE TO PAY 3000 DOLLARS TO REPLACE A PART THAT EVERYONE'S HAVING TO REPLACE OR YOUR CAR WILL LITERALLY BREAK DOWN FOR GOOD. THE PO50A CODE.

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.  To review the reports cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.
