The paint on my vehicle has been bubbling and chipping off for years. I did buy my vehicle used and was a certified pre owned. It was in great condition at the time of purchase. The paint became a problem soon after owning the vehicle. I didn't think much of it till it continued to peel off more and rust in certain areas. I noticed more vehicles like mine had the same problem. I began looking into it and seen that others were complaining of the same issue as mine online. I did contact Kias main corporate office and they wanted estimates and pictures. I did not go thru with this because they said it was a process to even get approved and if they approved it they would only paint certain parts, and not the whole car. I figured why paint parts if the same paint was used originally to paint the entire car then chips could happen anywhere else. …
On October 10th 2024, my 2015 Kia Optima caught fire while I was driving. The fire originated from the engine compartment, completely engulfing the vehicle in flames within minutes. Component/System Failure: The exact cause of the fire is unknown, but Kia had previously issued a recall for this model due to an engine defect that posed a fire risk. The vehicle is no longer available for inspection as it was completely destroyed in the fire. However, I have multiple videos documenting the incident, including footage of the fire and the aftermath. Safety Risk: My safety and the safety of others were severely compromised. The fire started suddenly while I was driving, forcing me to evacuate the vehicle immediately. If I hadn't reacted quickly, I could have suffered serious injuries or worse. Additionally, the fire posed a danger to other drivers and pedestrians nearby. …
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. …
Paint is peeling off my white 2015 KIA Optima on the passenger side, trunk and driver and passenger front pillars. The paint is peeling from underneath the paint at the base of the vehicle. This is obviously a paint defect and unacceptable. I was told by multiple auto paint body shops that "the paint did not fuse with the primer which is causing the paint to bubble and peel". Kia is telling consumers to put in a claim and send pictures, sales contracts and paint estimates etc. and then deny the claim. However, I know for a fact that they are picking and choosing which claims to take care of. My claim was denied but I refuse to accept this and asked for a Case manager to call me directly to discuss further. I am suppose to get a call back within a 5 to 7 days. …
I have a 2015 Kia Optima and the paint (Pearl White) is starting to peel of. It started on the front left of the windshield last December (2021) There is now the back right of the vehicle, the top of the trunk and the hood. After research on line, it looks like it is common on this paint type on the Kia models. I am seeking out some help to resolve this problem for everyone. I talked to my car dealer about the problem and told me that the warranty for the paint stops at 36000 miles. My car has 96021 and is not covered anymore, even if it is a defect. My car is starting to rust, no recourse from the dealer, need some support from the NHTSA department to resolve this problem that is not isolated to my vehicle only but many more. Sincerely,
A small spot the size of a half-dollar formed on the exterior paint (pearl white) on the passenger side rear door and has since expanded to the size of two fists. I brought the vehicle to a reputable body repair shop that was recommended by my auto insurance provider to get the area repainted. The body shop reports that the paint is "delaminating" and is not adhering to the primer. There are countless related complaints online from vehicle owners with the same year, make and model - yet no recall has been issued by Kia. There are no warnings to alert the driver to this problem. However, over time, the exposed metal will rust and the door will eventually corrode, putting the passenger at risk.
My 2015 Kia Optima has shown signs of paint chipping for the past year in the half. At first a minor inconvenience, now is becoming a major problem with parts of the body starting to rust and larger sections beginning to peel as well. While paint deterioration is expected on a car, it shouldn't happen as early as 5 years in or less than 80,000 miles. I am worried that paint will continue to peel off and the body work will continue to rust. The car has not been looked at by the manufacturer and various site across the internet have shown that the Pearl White Paint color is the sole color that has experienced this problem. The Hood, A Pillar, and rood railings are all experiencing this problem.
The paint on the vehicle is separating from the body. This vehicle is available for inspection at any time. The paint begins to peel and break off when it rains, and it washes into the drains. From there, it ends up on the grass where my young child plays, potentially getting on his hands and into his mouth. Additionally, animals like birds are picking at the paint on the grass. My insurance has verified this problem, and there were no prior signs that indicated any issues. Recently, following a storm, water started bubbling up beneath the paint, causing it to crack and eventually blow off. It started in a small area but with every rain gets worse.
The paint on my 2015 Kia Optima is severely peeling off, especially on the trunk, hood, and driver-side pillar. The passenger side also has some peeling. This is not a minor cosmetic issue - it significantly affects the vehicle's appearance and long-term durability. Many other owners of this model have reported the same issue, indicating a widespread paint defect. I contacted Kia through several official channels and received no response. I believe this is a manufacturer defect and should be addressed as a broader consumer issue.
