Issue: Kia Motors America (Kia) is recalling certain 2011-2017 Optima, 2012-2017 Sorento and 2011-2018 Sportage vehicles that previously received an engine replacement under recall number 17V-224, warranty, or the Knock Sensor Detection System (KSDS) Product Improvement Campaign. The high pressure fuel pipe that connects to the fuel pump outlet may have been damaged, misaligned or improperly torqued during the engine replacement procedure, possibly causing a fuel leak.

Issue: Kia Motors America (Kia) is recalling certain 2010-2013 Kia Forte, Forte Koup, 2011-2013 Kia Optima and 2011-2012 Kia Optima Hybrid and Sedona vehicles. In the event of a crash, the air bag control unit (ACU) may short circuit, preventing the frontal air bags and seat belt pretensioners from deploying.
Risk: If the frontal air bags and seat belt pretensioners are disabled, there is an increased risk of injury to the vehicle occupants in the event of a vehicle crash that necessitates deployment of these safety systems.
Remedy: Kia will notify owners. For model year 2011 Sedona vehicles, Kia will instruct dealers to verify the ACU part number and, if necessary, install an extension wire harness kit between the ACU Connector and the Vehicle Harness Connector.

The dealer is refusing to replace the engine under the previously completed Safety Recall Campaign SC147 (NHTSA Campaign 17V224000). The engine is currently exhibiting clear signs of connecting rod bearing failure—the exact mechanical hazard SC147 was issued to address. The dealership inspected the vehicle, confirmed internal engine failure, and verified that SC147 was completed on this VIN. However, they denied coverage citing an incomplete software update (Product Improvement Campaign PI1803) associated with a separate class-action lawsuit. The dealer is incorrectly conflating the requirements of the class-action warranty with the vehicle's independent eligibility under the safety recall. Independent of the class-action parameters, I am requesting a repair under the standalone 15-year/unlimited-mileage extended warranty provided specifically for vehicles that completed SC147 (detailed in the SC147 Safety Recall Campaign Q&A dated May 22, 2017, and Kia Warranty Bulletin 2017-09, both uploaded with this submission). The vehicle is well within this 15-year extended warranty period. Additionally, the PI1803 Knock Sensor Detection System update is a diagnostic detection tool, not a physical remedy for the underlying crankshaft machining defects identified in 17V224000. A manufacturer and its dealer network should not be permitted to use an unrelated class-action software prerequisite to invalidate a pre-existing, federally mandated safety recall warranty.
Steering flexible coupling was a recall over 10 years ago, it was replaced. The steering wheel “sticks” and it’s catching again and they will not do anything. I’m not happy that this is an ongoing problem and can be dangerous if it sticks at the wrong time!
Entire vehicle got burned while driving on the highway, the car is available at the impound shop for inspection. I was driving the car on the highway during the hours of rush hour when the car started burning, there were many drivers around on the other lanes. The NY Fire Department battalion and the NYPD responded to the scene and we have reports. The car was inspected by the NY fire department and a KIA inspector. There were no lamps or any warnings signs nor messages of any problem or failure.
Engine faílúre on June 26, 2026.Dies while moving. Engine died while turning from my side street onto busy street and traffic.I could've been struck in the rear had I not pulled out far enough in advance for the traffic to move around me. This is a second engine failure for my Kia. The engine was replaced in December 2023/ January 2024. Incident #11558201. It does not immediately restart. After some time (about an hour) it takes a long time for it to kick over then finally starts. When beginning to move forward it travels approximately 100-150 feet then dies again. A gentleman stopped to see if he could help. He thought the fuel gauge was broken and just needed gas. (Gas tank was full). Then he put the car in neutral and pushed me home with his truck. Then he helped me push it up into my driveway. I haven't gotten to the dealership (Ferguson Imports) Kia because of the cost of towing which I am responsible for if I wish to have it seen by a service specialist. It is available for inspection upon requést.

The clock spring keeps failing which is causing the air bag light to remain on; the horn to not work; various functions of the dashboard; and steering wheel heat.
The horn stops working, steering heat stop working, control functions and air bag warning. I changed the clock spring and it fixed all those issues the first time but within 6 months all those issues happened again. Is there something more wrong?
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. However one day the check engine light did come on and the OBD code P1326 came up. When I took it to the shop the check engine light disappeared and the dealership said they will not check my engine unless they see the code on their end. 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.
Sudden engine failure while driving with no warning. Vehicle began jerking, shaking, and losing power. RPMs dropped unexpectedly and the engine stalled intermittently. Multiple misfire codes were present (cylinders 1, 3, and 4), and the engine was found to have low or no compression in cylinder 1. The condition rapidly worsened to near complete engine failure. The vehicle was operating normally prior to this incident. This failure is consistent with known Kia engine defects involving internal engine damage, including rod bearing failure. This is a safety concern due to sudden loss of power while driving.
When the brake pedal is pressed on the brakes will grab. It snatches the car kinda hard. Also when you give the car gas it will hesitate and will not accelerate. Another with the gas is that you can be driving at a higher speed such as 45 to 55 or so and you press down the gas pedal like your going into passing gear and it will not accelerate it’s like it’s trying to stop. Feels like the car is gonna fall on down onto itself and it loses power.
