The contact owns a 2015 Kia Optima. The contact stated while her granddaughter was driving at an undisclosed speed, the vehicle lost motive power and there was smoke coming from the front end of the vehicle. The driver was able to pull to the side of the road and turned off the vehicle. The contact met her granddaughter on the side of the road. Upon inspecting the vehicle, the contact noticed that the smoke was coming from underneath the vehicle, under the engine compartment. The vehicle was towed to an independent mechanic, where the contact was informed that an unknown wiring harness had burned, but the cause of the failure could not be determined. The vehicle was towed to the dealer, where it was diagnosed that the engine had seized and needed to be replaced. The was not repaired. The contact related the failure to NHTSA Campaign Number: 21V331000 (Service Brakes, Hydraulic); however, the dealer informed the contact that the repair could not be covered under the recall. The manufacturer was not notified of the failure. The failure mileage was approximately 107,000.

Drove this 15 Kia Optima on the highway when all of a sudden it lost power and died. There was no lights or symptoms prior to this happening. The vehicle ran as it should up until the other day, the Engine had no codes or lights on in the vehicle.. Then without any signs at all the vehicle stalled and almost caused an accident on the highway and the would not start. Barely made it to the breakdown lane. We had it towed to a shop and We spent some time checking the Kia over to find out the starter had melted. We installed a new starter and now the engine has a very loud knocking sound that was never there before. Based on reading the safety recalls and bulletins on this Kia and issues surrounding this vehicle online, we should meet the criteria for a claim. Can you help me please!!!!

The contact owns a 2015 Kia Optima. The contact stated the vehicle failed to start-up. No warning light was illuminated. The vehicle was towed to an independent mechanic where it was diagnosed that the oil level was extremely low. The contact was unaware of any oil leaks. The local dealer was contacted, but the vehicle was not diagnosed or repaired due to the cost of towing the vehicle. The contact received notification of NHTSA Campaign Number: 23V652000 (Service Brakes, Hydraulic) after the failure had occurred. The failure mileage was approximately 184,000.

I have 3 issues currently going on with my 2015 Kia Optima. The first is the Oil Control Valve. This is supposed to be covered under my extended warranty that I pay for. If I didn't have the extended warranty I would be responsible for putting a new engine in a car with less than 60,000 miles on it. However, it will take time for the adjuster to come out and then to decide if the entire engine should be replaced which would then take even longer. The second issue is the O2 sensor which is part of the exhaust. Apparently in a care with less than 60,000 miles on it it's not unusual in the Kia Optima for this to go bad. Kia knows this is an issue but hasn't done anything about it. Lastly, the Stop Module in the braking system needs to be replaced. After hitting my brakes at a red light the ESC light came on and the brake lights don't go off. It's very dangerous as no one behind me can tell if I'm stopping or not. There was a previous recall for the HEC system which I had fixed. Per that recall brake fluid can leak and cause an electrical issue within the brake system but my Kia dealer service department is telling me it's not related to the original recall. I think it is and I think Kia should make the repair with no charge to me on a car with less than 60,000 miles on it. How does the engine, the exhaust system and the electrical system all go bad at the same exact time? This is unacceptable.

- The issue occurred for the first time 4/30/2024 - The following 3 warning lights appeared while I was driving: ABS, Traction Control, and Brake - I took the vehicle immediately to a facility to have the warning codes read. The printout showed: C2402 & C2380 - The warning lights remain illuminated every time the vehicle is turned on - I believe there is a safety concern of a potential fire or brake failure

I received a safety recall notice in November 2023 stating that there is defect with Hydraulic Electrical Control Unit (HECU) in my car that can result in an engine compartment fire either while I am driving my car or when it is parked. As of April 2024, I am still waiting to be notified that the part to fix this issue is available. This delay is putting my life and my children's lives at risk every time we drive in our only car, as well as the drivers around me if my car catches on fire when I am near them. In addition, this issue puts our home, as well as our neighbors' homes, at risk of catching on fire since I am not able to park outdoors away from other cars and structures as was recommended. In the past few days, I have felt a difference in my car's performance and today 04/19/24, the Malfunction Indicator Lamp (MIL) warning light turned on. According to the notice I received, I am supposed to stop driving my car and have it taken to a dealership immediately if this happens. However, I called my local dealership, and the earliest appointment available is on 05/13/24. I have no other car and cannot afford to drive a rental car for almost 30 days. I have been placed into a horrible situation because of this major issue. I have to risk my safety every time I am in car and even when it is simply parked because of this. This is completely unacceptable, and Kia should be held responsible immediately as I have no other means to remedy this problem.

I was driving in downtown Gilbert when I pulled up to a red light. My car would not inch forward when taking foot off brake. I then had to put my foot all the way down to get my car to drive. When taking a turn my car would run perfectly until I stopped. Then we pull up to parking garage and the car just stops without while in drive so I put it in park and then turn it off and then back on and it works again. I had the alternator, battery and starter checked and they were all good no issues so why am I having electrical problems with my vehicle Kia needs to fix this.

Hello, I am writing a complain in hopes of getting some type of help to try and recover damage on my car. I own a KIA OPTIMA 2015 and sometime in November of 2023 I received a letter in the mail stating the car had a recall on it that could result in the car catching on fire. While I was waiting for the remedy letter to come in less than a month after I received the recall letter the car randomly caught on fire. I strongly believe that it had to do with the recall because the car was Fine before that and had no check engine light on or anything on the dash board. The car was parked in the backyard of my residence in which the letter did warn to park away from any residence if any light was on in the car but at this time no warning light was shown on the dashboard. At this time I was taking my brother who is a minor to school when it happened.It was around 8am in the morning when I had turned on the car to let it warm up and as I ran inside the house for less than 2 minutes I came back to the car shut off making a weird noise. When I tried to turn it back on it took less than a minute and it started to catch on fire. I did have to call the fire department as the flames moved fast and were uncontrollable. My insurance unfortunately was no help in helping recover anything and when I reached out to the kia company after 2 long months of waiting on answers I was told that they could not offer no type of reimbursement as they aren't sure how or why the fire started. They said that the fire started in the compartment of the passenger side which the recall letter did mention something similar to that.Kia company does not want to take any responsibility in their mistakes and just brushed me off. I am now left with no car and a bill that I am waiting for in the mail from calling the fire department. Not only was my life in danger but so was my brother as he did suffer a panic attack from how scared he was that day. Please assist in what I can do next. Thank you

HI, I own a 2015 KIA OPTIMA. Sometimes when I drive it, I get a burning smell from the dashboard/engine after driving it after a while. I received A KIA recall notice regarding an electrical short circuit in November 2023. The notice said that the electrical short circuit could cause a fire, which I think is the cause of the burning smell. When I called KIA to bring the car in, they said there is no remedy to fix it yet. So I receive the notices in November 2023 and at the time of writing it is March 5th 2024, five months after and KIA does still does not have a remedy to fix the problem. I think this is a major safety issue that is not solved in a timely manner as there is potential risk of fire every time I drive my car. I hope NHTSA can step in and have KIA expedite a remedy to fix this hazard that can lead to potential injury and/or death. Thank you Concerned KIA owner

I purchased my car in 2015 at 23k miles, now we're at 86k miles and I'm experiencing issues. How is there a recall for this car but no remedy yet when there is a high risk of fire" Shouldn't there be a resolution for this safety concern" I noticed my car in 2022 would smoke here and there when driving, and I would smell burning. I took it to my mechanic and he changed the head gasket, and the smoking stopped. There is residue on my engine from a leak from the oil. My mechanic at the time told me I might still smell burning oil just due to that. As time went on things were fine but a year later, the oil smell came back stronger. I notice it only on longer drives, so I do believe my car is leaking oil. Also, the amount of time I've changed my break lights this year and head lights. They dim so fast over time and eventually go out to where I have to replace them. There is 100% an electrical issue going on.

The contact leased a 2015 Kia Optima. The contact stated that the front passenger's side window, the rearview camera, and the brake lights were intermittently inoperable. Additionally, the contact stated while driving at approximately 10 MPH, the check engine warning light and several unknown warning lights illuminated, and the vehicle shut off. The contact shifted into neutral(N) and was able to push the vehicle to the side of the road with the assistance of several bystanders. The vehicle was towed to the residence. The vehicle was then towed to the dealer where it was leased, and it was diagnosed that the engine had seized and needed to be replaced. The engine was replaced; however, the failure persisted. The contact stated while driving at an undisclosed speed, the battery warning light and the steering warning light illuminated, and the vehicle shut off. The contact was able to jumpstart the vehicle and drove to the residence, where the vehicle remained parked. The vehicle was not repaired. The Kia dealer and manufacturer were not notified of the failure. The failure mileage was unknown.
