Selected complaints filed with NHTSA by 2016 Kia Optima owners, lightly cleaned up (personal details are redacted by NHTSA).
I was told that my engine had a recall on it so I had an upcoming appointment with Kia in like 2 weeks for them to check my engine but the car didn't make it. I was driving my car on interstate 20 my car had began to have a bad chemical smell and started smoking so I pulled over on the interstate and my car was in flames. Me and my daughter was in the car we could have lost our lives thank God we were able to make it out just in time. The fire department came and made a report on the incident. It wasn't any engine light on at the time. I have contacted Kia about the tragedy that has happened but nothing has been resolved yet.
The body shop later informed me that there is a recall for engine fire recently,but my year/make is not listedin the info obtained online. The car started stalling while driving down the off. Smoke started coming through the vents. I pulled over to the side of the highway. A passerby told me that the car was on fire. Called 911. To note I had just picked the car up from Jim marsh Kia for battery replacement and problems with steering after the car was stolen in July. I had no previous issues with my car other than routine maintenance which I have records for.
The contact owns a 2016 Kia Optima. The contact stated that while driving in a heavy rainstorm, the vehicle experienced water intrusion causing the sub frame undercarriage to become damaged and unsecured. The vehicle was not yet repaired. The local dealer was notified of the failure, but no assistance was offered. The manufacturer was not yet contacted. The failure mileage was 14,000.
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. …
My 2016 Optima has the Pearl White paint. In April 2018 I noticed that it started peeling on the hood. The dealership told me that since I was past the 36k mile warranty (I was at 39k miles then) that I would have to cover the cost out of pocket. It's sad that the vehicle was not even 2 years old and that the paint was coming off and the dealership basically told me "oh well". I am now scared to hand wash the vehicle for fear of it getting any worse. If Kia knew/knows there was an issue with the paint, why don't they just make it right? It's now all over the car that it has peeled off, not just exclusively to the hood, and theres even rust that has started to show up in aomw of those paintless spots. I have always hand washed the vehicle, waxed, never taken to a car wash either. You can see from the pictures provided that this is not caused by rocks or pressure. …
2 of my windows drop when i go over a speed bump....i have already gotten the motors replaced for the windows (front driver, and back driver sides)....i don't even use the POWER up/down FOR the back windows AT ALL because i am the only one that drives my car (wondering why this is happening for this)....when i took my vehicle for these windows to be replaced, even my mechanic says there should be a recall on these windows and that this should not be happening....NOW my back passenger window is doing the same thing and again i don't even let the BACK WINDOWS down...someone can break in my car by just literally SLIDING the window down (OMG!!!!!!!!)....there are no warning lamps for this..i noticed this happening when KIA fixed one of my recalls
I bought this car with just under 48k miles September 2023, it had a very small chip on the bumper that I assumed was from a rock. After driving this car for a while, I noticed that chip got bigger and eventually other parts of my bumper and hood started bubbling and chipping as well.90% of my bumper is now lacking paint and it's starting to chip on my hood more. I've only driven it an additional 12k miles since I've bought it. Auto body shops are saying it's delaminating and it's common in this color.
The paint is peeling or delaminating from the car. It is happening in many places. The paint is Snow White Pearl. The car now has about 110,000 miles. The paint warranted for only for 36 months. But it is obvious that this is a quality issue and latent defect. The paint shop says he has seen this a lot with Kias. The paint is not sticking to the primer. I keep hoping there will be a recall on the paint. Even the dealer says it is a problem but Kia corp will not pay to fix the cars with this issue.
Soonroof/Moonroof closed rattle noise. When the Soonroff/Moonroof is closed at highway speeds or windy weather it make a rattle noise to inside of the car, i try to do their reset method and nothing worked, i being looking in kia forums and most of the people had complained about this issue, and that kia doesnt wants to fix. I will like an investigation of this issue and if you can start a repair campaign recall due this soonroof parts are really pricey. And i think is a manufacturer problem.
While driving on the highway, the roof antenna assembly flew off our car. Inspection of the area shows that the screws that were supposed to hold the antenna on had all become sheared off. It looks like there is a recall for this exact issue covering 2016 Kia Optimas produced through June 1, 2016 (SA272), but our Optima was produced on June 23, 2016 and is therefore not covered according to Kia.
