My engine locked while driving on the highway, I have got the car inspected twice since I purchased it and only had it for a year and it passed, everything worked fine and no hazard lights were on dashboard until it stopped then the battery and engine light showed when stopping! I had no problems with the car prior to it, just stopping on me I had my kids with me and we were going to another state so that-??s dangerous! I had to get it towed to a Kia dealership and was told they had 4 recalls on my car and the problem was the engine locked but I was told they would not do it free of charge or under warranty because the car has a salvage title overall the car was still drive able and in good condition up until that point.

My car started smoking while parked at work for no reason and I had to call the fire department. It stop smoking by the time the fire department came. I had it towed to the Dealer. My brakes are a mess but especially on a wet road you have to pump them to try to stop. I have taken it to the Dealer and of course they find nothing wrong. I told them to test drive it on a wet raining day and try to stop hard. Supposedly they could not but I have almost been it several accidents and had to run through a red light because I could not stop. So, I try to drive this car on a rainy day or drive slowly. This car has been trouble since I got it and the dealer will not listen.

My Kia optima has been having engine issues regarding fluid spilling in different components of the vehicle, first started within spark plugs, then in the exhaust camshaft, once I fixed those two issues it's now spilling within my wiring hardness. I was told to fix my valve cover which I did but oil is still spilling out from the engine and into other components. The vehicle stalls while driving on the highway which is unsafe for myself and other drivers due to the speed slowing down without warning until after the decline in speed. I've went to an independent service center, but once new issues arouse I assumed he was just trying to get more money out of me but I even brought it to Kia and still seems to have issues occur. I received an engine light warning when the vehicle stalls, there is times where the car actually turns off but not completely ( I guess due to the car being in drive mode) and I have to actually push my engine start/stop button for the engine to start again.

1st problem happened when I was at a complete stop, at a traffic light, in rush hour traffic. All the sudden steam started coming out from underneath my hood. I instantly looked at my temperature gauge and it did not show anything however I knew something was wrong when the light turned green I immediately pulled over, out of the street as far as I can get without being hit by other cars. I put on my hazard lights. Pop the hood. I had a gallon jug in my trunk. And I walked to a store to fill it up with water. Came back, poured the entire gallon into the radiator. Waited for at least 30 minutes. Started the car and made it home. After that incident, the problems with this 2015 Kia Optima has snowballed. It just amazes me that it has started happening 2000 miles after my extended warranty expired. I had to purchase and replace spark plugs, the coil packs, two other sensor things, which I do have the receipts for and now the car reeks a gasoline and it automatically kicks into overdrive and I lose my reading on my tachometer, this puts it into a disabled mode, I'm on the freeway in Russia traffic, trying to pull over without getting into an accident. Do I believe this is a safety concern? You're damn right I do am I mad yes. I am taking my k i a into the dealership. After doing my research on this make and model, is the dealership doesn't honor what the claims department and the media response to this problem. Will then I will leave the car with Kia because I cannot afford a new engine. I will have to call to finance company and let them know that I voluntary I'm letting them come repo this car, good luck selling

I was driving the car 30 mph and the engine just cuts off completely and dies in the middle of the road in traffic. It wouldnt start. There was no time given to pull off the roadway. I get to safely call a tow truck which took them 3 hours to get there. They took it to Kia and there Kia says it has 4 recalls and the engine is seized up. Even though Kia is responsible for motor replacement and has replaced motors in other Kia's they have denied me of a new engine die to their recall. I have paid dearly for that car for 6 years now that im a thousand away from paying it off and having my sanity Kia almost gets me killed on the street and took what sanity I have left. They say they are not going to fix any of the recalls on my car.

My 2015 Kia Optima EX with 56,462 miles which I am the original owner. On 09/07/2024, my vehicle oil light came on and the vehicle was taken to Weston Kia in Gresham, OR. This vehicle has had regular oil changes every 3,000 miles since purchased performed at Weston Kia. The service department found a leaking oil pressure switch and preformed the repairs totaling $248.60 on 09/08/2023. Per Kia 10yr/100,000 Powertrain warranty for original owner "In the Engine: Cylinder block, cylinder head and all INTERNAL PARTS, timing gear, seals and gaskets, valve cover, flywheel, OIL PUMP, water pump and turbo charger, pg. 6." I believe this part is covered per Kia warranty and the definition of drivetrain "A powertrain is a system inside a vehicle, in a car, a powertrain consists of the engine or motor and its internal components, such as the energy storage system, transmission and driveshaft." After reviewing all Kia warranty information and speaking to customer service at 800-333-4542 (Who stated the repairs are not covered), there is no information to the contrary that a oil leaking pressure switch that is located within the engine block is not covered. Kia would not provide any detailed information that shows this part falls outside of the terms of my 10yr/100,000 mile warranty.

I-??ve had my 2015 Kia optima since 7/11/23. My dipstick showed oil full. I drove it 977 miles from 7/11/23 until August 23 2023. My oil went from full mark on dip stick to low. My vehicle I purchased had 66,892. I should think it shouldn-??t be losing a quart oil in a little over a month. I had to add a quart of oil. This is unacceptable.

I recently got a 2015 Kia Optima LX, I loved the vehicle and decided to buy it. I had no issues until I decided to drive it, and after 30 minutes of driving, I faintly hear a sound coming from the engine, as if it's hitting some metal. Shortly after, a warning light on the dashboard turns on. I reach home and decide to scan it with a small OBD scanner I have, and to my surprise, it's showing error code P1326. The vehicle is running very poorly, making a sound like metal rubbing against metal, and it has no power at all. I'm stuck on the road with the vehicle like this. It has 104,600 miles on it.
