The other vehicle fled the scene. The contact's daughter merged to the shoulder of the road. There was damage to the front passenger side door, and front passenger wheel well, and tire. The vehicle failed to restart. The police were on the scene however no Police Report was filed. There were no injuries reported. The vehicle was towed to a collision center for cosmetic repairs but the vehicle failed to start. The vehicle was then towed to a local dealer. The dealer diagnosed that the engine had failed and needed to be replaced. The dealer mentioned a recall related to the engine, but it was not eligible for engine replacement because the vehicle had not had a software update performed for the engine. The vehicle was not repaired. The contact had researched online and related the failure to NHTSA Campaign Number: 17V224000 (Engine and Engine Cooling). The manufacturer was notified of the failure. The failure mileage was approximately 73,000.

My paint is delaminating all over my vehicle and is flying off in large sheets. My car now has metal exposed which is susceptible to rust which poses a risk to the structure of my vehicle and the potential of my windshield flying off as a result. This first started occurring about a year ago. KIA fails to recognize this manufacturer defect and it continues to delaminate at an alarming rate.

ELECTRICAL SYSTEM, ENGINE
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 vehicle was taken to the dealer, where it was diagnosed that the Hydraulic Electronic Control Unit (HECU) had experienced an internal electrical short. The vehicle was not repaired. The contact stated that the vehicle was previously repaired under NHTSA Campaign Number: 20V519000 (Service Brakes, Hydraulic). The failure mileage was approximately 119,000.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, ELECTRICAL SYSTEM
- 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

UNKNOWN OR OTHER, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
Not sure what the exact problem is and my mechanic cannot figure out either, I had the car a little over a year purchased from carvana! First few months the brakes started messing up got caught in the rain ran into a trash can left minor scartches but nothing was wrong internally. September got side swiped on the highway not a reportable accident but I had to change whatever held the wheel literally everything that holds the right wheel had to be changed and after that incident a sensor came off, traction with wheels off but still drivable, about 3 days ago the engine just started making a cracking sound mechanic said it was some sensors he changed both and still making the weird noise, only had the car for a year and my mechanic cannot pinpoint the problem and suspects some type of engine issue which idk if it’s a recall on Kia optima’s or not because I don’t drive crazy!

The vehicle was taken to an independent mechanic, who determined that there was an oil leak in the engine compartment. The vehicle was not repaired.

I've been having an issue with my car just out of the blue breaking while I'm going into it seems to be only a left turn I had let Kia know about this when I took it in for the other recalls just recently nobody seemed to have any idea of what was going on or look at me like I was crazy I guess and now I see this recall that explains everything to a tee of what my car is doing I need somebody to contact me please. This has almost gotten me into serious accidents on more than one occasion

ELECTRICAL SYSTEM, ENGINE, UNKNOWN OR OTHER
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.

ENGINE, UNKNOWN OR OTHER
Driving to work, that is less than 5 miles, started to hear a noise then car just stopped, called roadside assistance , towed to dealership. Had to wait for their diagnosis… I should be under my warranty. I have 44,400? Miles so under 100,000 miles. Has 10 yr warranty also but is 9 years old. Car paid off. They diagnosed rod bearings out and need a new engine—- m/b 6700.00 to replace engine. It should be under warranty- they said they had 4 recalls on that car/ make & model. I was never NOTIFIED so that is now supposedly null & void my warranty because they said my problem.

ELECTRICAL SYSTEM, ENGINE, VEHICLE SPEED CONTROL
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.

ENGINE
Loss of power to engine when trying to increase speed to turn into traffic/getting onto the highway and constant severe engine knocking noise. I have to use hazards when turning into traffic/merging onto highway because the vehicle takes too long to catch up with the speed of traffic. It also has a problem with excess oil consumption, needs to be refilled every week and a half to two weeks. Bremerton Transmission has provided an inspection and a Diagnostic Trouble Code (DTC) P1326 (Knock Signal Range/Performance). The oil consumption has been an ongoing issue since I bought the car in February of 2022, only getting worse. The rest of the issues have been escalating problems.
