“While driving, my 2020 Kia Optima suddenly lost engine power and went into limp mode on the road, leaving me stranded and creating a severe safety hazard in traffic. The vehicle threw diagnostic trouble code P1326, which indicates a catastrophic rod bearing failure. The problem has been confirmed by a Kia dealership scanner. However, both the dealership and Kia America are refusing to cover the inspection and repair under their safety campaigns or goodwill due to the vehicle having 180,000 miles, despite this being a well-documented manufacturing defect inherent to these engines. Prior to the failure, the check engine light started flashing. The vehicle is currently available for inspection.”Owner report · Power Train · Sep 2026
“Today as I was driving to work my car suddenly stopped while being idle at the stop light. It turned off. I was able to restart and drive to work safely and home. I googled the issue and saw many Kia optima owners having the same issues and they're saying no codes or anything popping up. Should this be considered a recall.”Owner report · Engine · Aug 2026
“The contact owns a 2020 Kia Optima. The contact stated that while driving approximately 40 MPH, the vehicle intermittently stalled and lost automotive power, with an abnormal odor entering the cabin through the air vents. The vehicle was restarted and returned to normal operation; however, the failure reoccurred. The "Service In" message flashed on and off on the instrument panel. The vehicle was taken to a dealer where it was diagnosed and determined that the low-pressure fuel pump needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 145,000.”Owner report · Fuel System, Gasoline · Aug 2026

“Fuel Leak: I can smell heavy gas fumes inside the vehicle cabin. Fire Hazard: The vehicle is unsafe to drive due to an imminent risk of a fuel fire. Corporate Refusal: Kia Corporate refused to generate a case number and my local dealership refused to service the vehicle leaving a dangerous safety defect unrepaired on public roads. Mechanical Symptoms: The car is experiencing slow cranking, engine sputtering, and multiple dashboard warning lights.”Owner report · Engine · Aug 2026
“My engine failed while driving which put me and others at risk. It was confirmed by the Kia dealership as rod bearing failure. Which is a known recall on the Kia 2.4L Theta II engine. My specific VIN number is not listed on the Kia recall list. And Kia is stating that it does not qualify for a warranty replacement. Although it is the same engine with the known defect.”Owner report · Engine · Jul 2026
“I have a 2020 Optima, apparently there is a recall for the older models, yet mine is experiencing the exact same issues. Over oil consumption leading to engine failure. I have been in a rental for a month and a half due to fighting with Kia to correct the issue all while they drag their feet. Smells like another class action.”Owner report · Engine · Jun 2026
“Engine replacement needed at 99,782 miles. P1326 code continuously popping up. Also has excessive oil consumption and electrical problems concerning the forward collision system. Kia refuses to replace engine although the P1326 code is covered by lifetime warranty. The cause of the incident was defect in engine resulting in a recall of all 2011-2019 models. The 2020 Kia optima LX contains a 2.4L GDI engine which has identical problems relating to previous lawsuits.”Owner report · Power Train · Jun 2026
“I was driving on the freeway and my check engine light started to flicker and I felt my car shake and going to limp mode. I made an appointment with the Kia dealership and they told me the engine is failing. They submitted a request for a Goodwill case to Kia corporation and it was denied since there's no open recalls and is not covered by the extended warranty. the dealership recommended me to take my car and keep driving it even though it's unsafe the vehicle will not go above 50 mph and it starts to shake when driving I have tried to call Kia corporate and explain this situation but they have yet to follow up with me in my case”Owner report · Fuel/Propulsion System · May 2026
“Car is consuming oil every three weeks. Engine is going to burn if it does not stop. It's not in a class action but probably should be. It's been 4 months and over 1,000 spent.”Owner report · Engine · May 2026
“The rod barring failed in my engine. I broke down in the middle of the parkway with my daughter. This is my third Kia optima that has had this issue but the dealership is stating there is not a recall on this model. The check engine light did not come on except when the car lost all power.”Owner report · Engine · Mar 2026
