We took our 2013 KIA Optima 4D EX to the local Kia dealership for diagnosis of what we perceived to be a knock engine sensor issue. We delivered the vehicle at 0920, 5 July 2024. The vehicle sat at the dealership for 4 weeks waiting for the diagnosis which was ultimately that the engine needed to be replaced...under warranty. On 16 August 2024, after so many calls to the dealership (Spradley Kia, Pueblo) and Kia Customer Support, we were informed that the service ticket was closed. No reason for it to be closed...just closed. Warranty work not complete. No offer to complete any of the other recalls on the vehicle. Not only would we like all recalls to be complete we would really like that to be completed in a timely manner.

On [XXX] @ approx. 9:30pm while driving south on [XXX] between Pullman, WA and Lewiston, ID. my 2013 Kia Optima SXL turn off with warning, the engine turned off and never started again. no lights, smoke, smells or leaks. there were no noises of any kind come from the car, nothing to alert me there was a problem. at the time there was no music playing. My daughter was sleeping so the only noise was the car, if there were any noises from the engine they were not muffled by conversation or music. I called my wife who came up and I tried to jump it, thinking perhaps the alternator failed. Due to the location, we were not able to fully exit the highway, the car was a half tire width over the white line. This is a rural location not an elevated interstate, as such traffic though moving fast was not bumper to bumper. Next day I drove up and pushed the car about 100yards behind where it was, on the opposite side of the road. Then called a roll back to haul the car to a local shop. They were able to best guess the diagnosis as a seized engine. as the engine was not turning over, and manually turning the crank was not possible. I trailered it to my house, removed the serp. belt and was able to very slightly turn the crank with a 2.5ft long breaker bar. it is currently in my garage. Oil was changed recently; it was not low.

On 7/31, we had the HECU Fuse recall fixed at the Federico Kia Dealership. In 8/1, one day later, when driving the vehicle all of the car emergency lights came on, the engine started smoking and eventually caught fire. Fire department and police were called. Vehicle was toed to Kia Dealership. The next morning 8/2 we spoke with the service manager at the dealership, who was no help and gave us a 1-800 number to call Kia directly. Since this fire directly pertains to the part they -??fixed-?? the day before during the recall, we believe the dealership did not fix the issue and believe something they -??fixed-?? caused the issue as we have never had any prior issues with the engine.

I've had my car since late 2018. A couple years after having I've noticed it's burning oil. I made an appt at Evansville Kia dealership & was called the day before appt to be told the excessive oil consumption test was not part of the warranty. I asked what am I suppose to do keep spending money on oil" The mechanic told me to keep topping it off til it quits, cause he said it's going to quit. How is this safe" Not knowing when & where you will be when something happens. My car is now using a quart or more of oil every 500 or so miles. This is ALOT of money out of pocket.

While driving on the freeway I noticed my car wasnt going as I was pushing the gas and noticed all my dash lights were on like I was in accessory mode. I coasted to the edge of the freeway and decided to pop my hood and see if it was my battery cable that came loose. While waiting for traffic to break I noticed my hood looked alittle hazy like it was hot. When I was able to get out of my car I noticed black smoke coming from under the hood so I backed off and called 911.

Car stopped accelerating on the highway. Check engine lights and other lights went on. Dealership is refusing to inspect the car without the CEL staying on. My family's life is at risk as long as Kia deems this car safe to drive. The dealer and corporate refuse to inspect it without a check engine light staying on when starting up again.

I have maintained my car well since i first bought it. I was randomly cruising [XXX] 2024 at [XXX] and my car stopped and nothing worked. No ignition, my wheel locked, my brakes locked and all i could see was black smoke coming out of engine. I had recently changed the oil on 11th May 2024 so I know that wasnt the oil that messed my car up and on internet it shows the recalls for fire in engine.

We took the car in for the recalls. ASC245 Headliner plates - they state they still don-??t have the part. BSC2484QF HECU fuse. After they replaced the fuse, the car started losing power when driving, as well as the traction control lights were on, and the brake lights were on. I have read on the KIA forum this is happening to multiple people following the fuse replacement. We took the car back to KIA the same day and they told us it was nothing to do with what they did. We have now taken it to another non KIA mechanic. This is extremely dangerous and clearly related.
