I have a 2015 Kia optima bought in July 2023 from a used dealer. This is the 4th Kia my family have owned. Prior to purchasing I ran a car fax and checked for recalls. The dealer where I purchased it at also check for recall.. I also checked again today on your Kia website for recalls and the only one listed is the newest one concerning the fuse which I also received a letter in the mail on Monday. The car currently has 131,000 miles service has been maintained. On [XXX] the car just stopped running going down the road no check engine or any warning that something was wrong.. I had it towed on Tuesday to a local shop who then told me it needed to go to the Kia dealership which is about 20 miles away… I had to have it towed again.. once at the Kia dealership I would told that more than likely it would be covered 100% due to a defect in the engines… I received a call back on Friday and was told it would not be covered due to a product improvement that was not complete that came out in 2018… 5 years prior to me owning the car.. I never received any information concerning the produce improvement … Again it was check for recalls on the https://www.nhtsa.gov/ by myself and also the dealer… none was showing and to this day it is not showing.. I even check the Kia website today and it still does not show the product improvement needed…. I see that there has also been a class action lawsuit that was settled due to the defective engines… I assure you if I knew of a recall it would have been completed. This car is the only mode of transportation my son has. I am a single parent who works for a local government and I do not make nor have the $6800 for an engine replacement. I am still paying on this car as I had to finance it due to lack of funds to purchase… Again we did our due diligence to make sure the car was in operating order when I purchased it.. we check recalls car fax and did not know of the issues… this is the 4th family Kia car and I trusted the bra INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Engine started knocking

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!!!!

Driving on the highway at 60mph and the engine just shutdown and the car turned off. Fortunately, I was able to get onto the shoulder without incident. No warning lights came on until the engine shutdown. Tried to restart the engine after letting it sit for a few minutes, would not start again. Had the car towed to a local mechanic and they discovered that the engine seized. Hoping the service contract I bought when I bout this car used in November will cover the engine.

I purchased a brand new Kia from an authorized Kia dealership. The vehicle in question is a 2015 Kia Optima, white pearl in color. Since its purchase, I have maintained this vehicle ensuring that it is serviced regularly at authorized Kia service centers and taking all necessary steps to protect its exterior. Despite these efforts, I have recently observed a drastic deterioration in the paint quality of my vehicle. Specifically, the paint on my Kia Optima has been peeling extensively in several areas, including the roof, hood, and trunk. This issue not only affects the vehicle's aesthetic appeal but also raises concerns about the potential for further deterioration and damage to the underlying metal, which could lead to rust and other long-term issues. I have conducted some research and discovered that paint peeling issues are not uncommon with vehicles of this model and color. It appears that this problem may be linked to a manufacturing defect, particularly with the application and adhesion of the paint. I believe this to be a defect that falls under Kia's responsibility, as the paint should reasonably be expected to last much longer under normal use and care conditions.

Hybrid system malfunction
Other or unspecified, May 7, 2024
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, May 6, 2024
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.
