Engine 2

The component that failed on my 2014 Kia Optima was the engine. Prior to the malfunction there were no lights indicating a failure. My safety was put at risk several times as my car had completely shut down on the highway going over 55 mph in way of many vehicles causing police to shut down the highway. I took the car to several auto shops to test and there was no indication of engine failure. I’ve got my battery checked, front end alignment and oil changed on schedule. The car still malfunctioned. I had it towed to the Kia dealership in March after learning about the recall on the engine. The dealership confirmed that the engine was faulty and had been recalled. There were several other recalls on that model as well. After keeping my car for a few days and charging me a service fee, they decided not to repair the engine saying that the software was not updated prior to the engine failure and they refused to repair. I was instructed to remove my car from the facility. I called their corporate office and a representative also denied my claim saying that the mileage on my car was too great. I have not been able to get in touch with anyone that can help. The car is located in a shared parking lot amongst hundreds of tenants and close to residential areas. I don’t believe it is a safe area if there is a fire risk but Kia refuses to honor their recall. The car is available for inspection upon request if needed.

High pressure fuel This put me at risk because my car could have caught on fire if that gas leaked in a certain spot under the hood. Independent service center No warning signs. This is the second time, I am paying to get this done. There should be some type of recall on this part.

The dealer stated my engine repair is not covered under the recall/warranty because an ECU software update was not performed. I was quoted $8500 for engine replacement (Long block). I have owned this vehicle for 2 months, going on 3. I am requesting a review of whether this vehicle qualifies for any engine recall or safety-related warranty coverage, as the explanation provided by the dealership appears inconsistent.

My vehicle was leaking oil an oil change. My vehicle started having a knocking sound. I am a single parent of a [XXX] child. The car would suddenly stop while I was driving which put me and my daughter's safety at risk. I took if to Southern Kia Greenbriar dealership to have a diagnostic test on Jan 17, 2026. [XXX] from the dealership confirmed my vehicle needs a new engine. It could be covered under the recall, however I would need to show receipts of every oil change from 2017 to 2026. The dealership has had my vehicle for over 2 1/2 months. My vehicle or component has been inspected by the Kia dealership, but not inspected by the police, insurance representatives or others. I noticed my oil on my drive way Jan 10th and put additional oil in my vehicle. Shortly after I began to noticed the car suddenly stopping for no reason, then heard a knocking sound when driving.

Issue: My 2014 Kia Optima has repeatedly experienced overheating, flashing check‑engine light, and loss of coolant. The dealership has misdiagnosed the issue multiple times and returned the vehicle to me in unsafe condition. Safety Concern: The vehicle overheats while driving, the check‑engine light flashes, and the engine loses power. This creates a serious risk of engine failure while on the road. I am concerned about potential engine damage, stalling, or fire risk due to overheating.

While driving down the highway, my engine completely turned off. I was able to get to a safe location. When I tried turning the car back on, it would not turn back on. I took it to Kia, and they said I was covered under warranty due to their settlement. However, due to the salvage title of the car, they will not replace the engine, even though that is what their recall settlement covers.

The contact owns a 2014 Kia Optima. The contact received notification of NHTSA Campaign Number: 21V331000 (Service Brakes, Hydraulic); however, the part to do the recall repair was not yet available. The contact stated that while driving at an undisclosed speed, the vehicle lost automotive power, and smoke was coming from under the hood. No warning light was illuminated. The vehicle was taken to a local dealer; however, the contact was informed that the recall could not be repaired because other unknown repairs had not performed prior to the failure. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 130,000.

The vehicle is currently experiencing failure consistent with a U.S safety call {Technical Service Bulletin) related to the steering column. A diagnostic scan has confirmed error code C1259 (angle sensor signal error) that match those referenced in the recall documentation. The vehicle was taken to a local authorized Kia dealership in Ponce, Puerto Rico, where we were informed that no recall appears in their system and that the recall “only applies to the mainland United States”. This response is concerning, as Puerto Rico is a US territory, and this defect directly impacts driver safety and vehicle control. Given that this involves steering system failure, I consider this a critical safety concern.

Upon inspection it was brought to my attention that kia had known of a problem with a coupler in the steering that goes bad..they have extended the warranty..
