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. …

In March 2023 car stopped in the middle of an intersection with no warning. "Hybrid system warning" on dashboard lit up as well as all other lights. Dealer said repair was under warranty because of faulty spark plugs which were a safety recall. Prior to this all safety recalls were taken to dealer yet the problem still occurred. On July 2, 2023, the car stopped on the freeway. All lights lit up and the "Hybrid system warning" came up. The car began to smoke. The car was towed to Kia dealer they said the water pump needed to be replaced. The water pump was replaced with a certified Kia part. The car still would not turn on. Kia replaced the battery and said the engine needed to be replaced for $9000. They said we were out of warranty (10 years by 2 months). …

Vehicle: 2013 Kia Optima SXL VIN: [redacted] 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: [redacted]

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.

Hello, I had my vehicle's engine replaced by a dealership (Reason - recall on engine and failure on freeway that has me traumatized!!!) and due to the labor done at Kia Tullahoma, TN my transmission has failed causing a near mishap crash on the freeway due to transmission slip. Noticed transmission fluid leaking. After taking it to another dealership (Kia Anderson, SC) they inspected and said that the labor performed by previous dealership had caused the malfunction. Today (7-24-23) Kia Tullahoma, TN refuses to cover the new transmission that now I have to replace due to their negligence. Due to separation of the transmission to engine the output seals started leaking and causing the incident. May I add that the engine might be at risk due to this also. Please post or let Kia corporate. I will also make claim. Thank you!!

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 [redacted] 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.
