2013 Kia Optima power train problems

“The contact owns a 2013 Kia Optima. The contact stated that while a family member was driving the vehicle at 40 MPH, the vehicle stalled. There was no warning light illuminated. The driver pulled over to the side of the road where the vehicle failed to restart. The vehicle was towed to the residence, where an independent mechanic diagnosed the vehicle and determined that the engine and transmission needed to be replaced. The vehicle was not repaired due to the cost. The dealer and the manufacturer were not contacted or notified of the failure. The failure mileage was unknown.”

“Vehicle: 2013 Kia Optima SXL VIN: [XXX] While driving on a highway at approximately 55–58 mph, the rear driver-side electronic parking brake (EPB) motor housing failed with a loud bang. Immediately after, there was heavy smoke and a strong burning smell. The vehicle became very difficult to drive, and the wheel began screeching and dragging as if the brake had locked. The failure appears to have caused the rear brake caliper to seize while the vehicle was in motion. This created a dangerous driving situation at highway speed and could have caused a crash. The brake system component that failed appears to be the electronic parking brake actuator/motor assembly attached to the rear caliper. This was a sudden mechanical failure, not normal brake wear, and it occurred while driving at speed. Kia care case number: XXX”

“The engine began exhibiting symptoms consistent with the known bearing wear defect covered under the manufacturer’s safety recall, including knocking noises, loss of power, and engine malfunction. The condition worsened to the point that the vehicle became unsafe to operate due to the risk of engine seizure and sudden loss of propulsion while driving. The vehicle was inspected by a Kia dealership, which confirmed engine damage consistent with the recall defect. The engine remains available for inspection. Despite an active, unrepaired safety recall for engine bearing wear that increases the risk of engine seizure and crash, the manufacturer and dealership have refused to perform the recall remedy unless the owner first replaces the engine at personal expense. The manufacturer has stated that the recall cannot be performed due to the current condition of the engine. This refusal leaves the vehicle with an open safety recall and no manufacturer-provided remedy, creating an ongoing safety risk due to potential engine seizure and loss of power while driving.”

“I have had 2 incidents of engine ceasure in my 2013 Kia Optima SX w/ Limited package. Once it ceased on the freeway causing me to have a minor collision with the offramp guide rail and just recenting on 10/18/2025 it happened again on the 405 with loud knocking sounds engine light flashing and no real engine power after ceasing. My engine was previously repaired under warranty with case number XXX which should have extended the warranty along with the existing recall for the GDI engine. I need help to get KIA to repair/replace under warranty as my engine is covered in the Theta II class action settlement. Kia repeatedly tries to dodge responsibility for repairing my car under warranty.”

“Car was in park at our home and not running. I was outside and noticed the car rolling backward. I thought my wife was leaving at first, but then noticed no one was in the driver's seat. I ran after the car got the door open and was pulling on it to stop it when it became stuck in a ditch between my driveway and the neighbor's driveway. After getting the keys and trying to start the car, it would not. The shifter was all the way in the park position but the reverse light was lit up. I used the shift release so I could move the shifter. I moved it out of park down to drive and back into park. I could then start the car, but I could not get the car out of park. There is an active recall on Telluride for a similar issue, and I have found other reports of 2013 kia optimas doing the same thing. This is a major safety issue as the vehicle could start rolling at any time.”

“Bought car 2020, engine failed and was consuming oil like it was fuel after 50-60K miles in 2022, Serra Kia Misdiagnosed and charged me $900 for ignition coil and combustion chamber cleaning that was not needed nor refunded when I was denied replacement due to me NOT letting engine lock up(Service manager basically told me to do so to be approved) or a P1326 code, charged +\-$8,000 for engine to be replaced. Horrible experience, engine was fine at first, then shortly after the SHORT mileage warranty they give, the engine started having minor non catastrophic issues here and there. Finally, around the same amount of time(last October 2024) and almost the SAME AMOUNT OF MILES on the engine, its doing EXACTLY what it was when i took it to KIA for the engine. One random day, on my way to work, i got to a red light and when i went to go at green the engine hesitated and i noticed a MASSIVE smoke cloud behind me and coming from my engine. It was consuming oil yet again the same way. Reached out to KCC(Kia Customer Care) and provided them a 4 page personally written letter by myself explaining the full story and my experience. However they merely closed my case…”
