“Had the software update for piston recall in April 2025, did all the testing and getting codes p0300 all the way to p0305 being that it only has 4 cylinders a 5th cylinder misfire code leads to piston ring failure, it is also burning oil the spark plugs are ashy which I have photo evidence of all of this and they are covered in oil, my car broke down while driving and lost complete engine power I am medically complex. Dealerships are denying the recall as it was "completed" due to a software update. This is a known safety hazard and I could have died. I have all proof it's the spark plugs failing.”Owner report · Engine · Sep 2026
“Was driving and power steering became difficult to steer and a red steering wheel icon with a exclamation mark came on in the dashboard.”Owner report · Steering · Aug 2026
“My 2021 Kia Seltos stalled twice while driving and failed to restart, creating a severe safety hazard. The vehicle was previously inspected twice at a Kia dealer for the Piston Ring Recall (SC209). The dealer diagnosis now shows timing failure codes P0014 and P0017 with misfires. The technician notes that the engine oil is entirely 'metalized' and the oil control valves are contaminated with metal debris. Kia is attempting to charge me $7,182 to fix a failure caused by the exact oil starvation symptoms of their active federal safety defect.”Owner report · Engine · Aug 2026

“Randomly started having engine issues in July 2026. Had an appt with Kia dealership and said my engine needed to be repaired with assumptions on what the problem is. They claimed it had nothing to do with the engine recall on my Kia and that it was my responsibility to pay for the repair. There has been 2 separate recalls on this car for engine issues which Kia is refusing to deal with or take care of. My car has been serviced by Kia dealership since I bought it in 2020, I also noticed in all my service receipts/reports that they were putting the wrong oil in my car and who knows if that is what caused my engine to start having issues. Car is unsafe to drive.”Owner report · Engine · Jul 2026

“My engine is damaged and needs replacement. My car starting stalling, when I put the car in reverse the car would stop working, the car starting vibrating and my check engine light came on. When I took it to Southwest Kia dealership, they pulled the recall and stated that the symptoms I was experiencing were what was described in the recall. However, the warranty has refused to repair the recall. I have been without a car for almost 6 weeks. The warranty keeps saying my VIN is not associated with the recall.”Owner report · Engine · Jun 2026
