2016 KIA OPTIMA Complaints

I am submitting a defect complaint regarding the paint on my vehicle, which has been progressively deteriorating. The issue begins as small bubbles in the paint, which eventually lead to peeling and complete paint loss in affected areas. This condition is currently present on the trunk, roof, and rear sides of the vehicle, and early signs are now appearing on the hood. This defect is more than cosmetic. As the paint peels, it exposes the underlying metal panels to environmental elements, increasing the risk of corrosion and rust. Over time, this can compromise the structural integrity of the vehicle. Additionally, significant peeling—particularly on surfaces like the roof or hood—can create glare or release debris, posing a potential safety hazard and distraction to both myself and surrounding drivers. I initially brought this issue to a Kia dealership, where the manager advised me to contact Kia Customer Affairs. Upon doing so, I was informed that the issue falls outside the warranty timeframe. However, after speaking with other Kia owners experiencing similar problems—especially with the same paint color—it appears this may be a widespread manufacturing defect rather than normal wear and tear. Furthermore, a professional paint specialist evaluated the condition and indicated that the bubbling and peeling are consistent with poor paint adhesion or a defective clear coat/mid-coat application during manufacturing.

The contact owns a 2016 Kia Optima. The contact stated that while driving 70 MPH, the check engine warning light illuminated. An independent mechanic was contacted. The vehicle was taken to an independent mechanic to be diagnosed. The contact was made aware of a misfire coming from the engine. The vehicle was not repaired. The manufacturer was notified of the failure but offered no assistance. The approximate failure mileage was 160,000.

For a second time, the window goes off the runner and will not operate. This happened to the drivers side window and the rear drivers side window. The only option is to return to the dealership and have the part replaced to allow the window to move up and down, This is a safety hazard and fails state inspection if the windows will not move up and down. This is a safety recall.

The Kias have been recalled for a failure to adhere the shark fin antenna. This has been recalled in some models. My 2016 has fallen off and is not on the recall list. Please include.

I purchased a vehicle from Banter Auto here in Wichita, Kansas. I reviewed the Carfax beforehand and nothing stood out that scared me so I signed off and purchased the vehicle. I have had nothing but problems since buying which was 7 months ago and have spent $9000 on repairs. I’ve been told by several mechanics the last 5 times I’ve been in and out of mechanic shops it’s evident my car sat in deep water for a long period of time. I finally took it to an electrical auto specialist here in town and while he said it is evident my vehicle sat deep water for a period of time and while the corrosion hasn’t quite started to cause an electrical problem that it very well could down the road. I’ve given the man who owns the dealership and opportunity to make this right however he stopped responding. I believe that is illegal and I’ve been told it should’ve been a “flood title”. I will know for sure after seeing a I will know for sure after seeing an attorney this week. That was not disclosed to me or I would definitely would have not purchased the car. When I first got the car, the locks and windows were going insane flickering all over the place and Kia dealership told me it was quite crazy and nothing they had seen before, however, they were able to fix it. I strongly believe that when my car was flooded it caused something to happen that I’m only going to have to keep paying for overtime. I’m already in debt from the $9000 I’ve had to getting personal loans. This is causing me enormous emotional distress. Please help.
