I WAS TOLD BY THE DEALERSHIP THAT MY 2018 KIA OPTIMA PHEV WAS REPAIRED BUT AFTER I DROVE IT OFF THE LOT AND GOT ON THE FREEWAY THE WARNING LIGHT CAME ON AGAIN AND LOST ALL POWER. I ALMOST GOT INTO ANOTHER ACCIDENT BECAUSE OF THIS. THE DEALERSHIP SAID THEY WORKED WITH KIA TECHNICAL SUPPORT TO FIX MY CAR BUT APPARENTLY KIA DOESN'T KNOW WHAT'S WRONG WITH THEIR OWN CAR. THE VEHICLE HAS ONLY 19K MILES. I'M AFRAID FOR MY SAFETY AND MY FAMILIES THAT THIS WILL CONTINUE TO HAPPEN.

Loss of Motive PowerClosed
The National Highway Traffic Safety Administration (NHTSA) received a letter dated July 13, 2022, petitioning the Agency to initiate a safety defect investigation into loss of motive power allegations attributed to oil drain pan assembly failures on certain Hyundai Motor America, Inc. and Kia America, Inc. vehicles spanning Model Years (MY) 2005-2021.

Engine FiresClosedLed to recall 23V877
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.Â During the PE investigations, Hyundai and Kia issued several recalls to address vehicle fires, including those due to engine failures involving various engine types.Â The remedies for the engine failure recalls typically involve engine inspection (to detect existing damage), and if necessary, engine replacement.Â 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…
