2013 Kia Optima Complaints

The vehicle is experiencing sudden engine stalling while in motion, a known safety hazard. Despite a documented maintenance history with no issues, the dealer (Bayside Kia) is attempting to deny a Theta II Settlement claim by shifting the narrative to 'engine sludge,' which only appeared as a symptom in June 2025( Walmart oil change) alongside engine performance issues. The vehicle has active codes P0014 and P0017, which are secondary symptoms of the internal bearing wear and metallic debris contaminating the oiling system. KDS Diagnostic tests showed Cylinder 1 at 0.16mm (approaching the 0.20mm failure limit). This clearance proves the connecting rod bearings are worn and reaching the failure threshold; this mechanical wear is the root cause of the engine's inability to operate safely. The presence of metallic debris in the oil is the definitive signature of the Theta II manufacturing defect. Furthermore, the dealer acted in bad faith by attempting to charge for Airbag repairs (Codes...

We were told by the mechanic that the engine was locked up after the car refused to drive faster than approximately 23 mph. We had to have the car towed from Boone, NC which was about 200 miles. The car is at our house and is available for inspection upon request. I have made repeated calls to different Kia dealers asking for a call back to assist me with direction but there will never be a returned phone call. As far as I know, there has been no inspection of the engine or vehicle.

Code : P1777 Transmission- oil pump A issue with the Valve cover gasket leaking into the engine causing a misfire. Making the car suddenly stop while driving which is very unsafe. I took the car to the dealership and they want to charge me for the repairs. I have 2 kia optima hybrid and both cars have the same issue around the same mileage. There were no warning lights during the time it was at the shop. I believe later down the line the engine will stall out and it should be fixed now while under warranty. However I received no help from the dealership unless I am willing to pay upfront. In addition to this there are electrical issues the front seats aren't moving immediately when the button is pressed. The steering wheel buttons barely work along with the radio. This is a huge problem that needs to be fixed.
