The wiring in this vehicle is soy-based and is attractive to rodents. I have experienced rodent damage twice now totaling about $3000 in damages. I have contacted Kia and they suggested making a claim on insurance. The first time damage occurred was in 11/2019 we made a claim on insurance. This time we will pay out of pocket because of the fear insurance might drop us for making continued claims. This seems to be a known fact about the soy-based wiring, yet Kia is not willing to assist.

Three out of four windows have stopped working. It started with the rear passenger window about 6 months ago, then the rear driver 3 months ago, and now the front passenger about a month ago. Did some research to find it's a pretty common problem on Kia's for the regulators to break. I didn't have the money at the time to fix the first one, was saving up and then second one stopped working. Definitely didn't have money for two, when third quit. Now just waiting for the last one to keel over. I don't know the exact problem, but I don't have money to fix all four windows at one time on a car that's only four years old.

3rd window motor that has failed in just a few months! first my back two window motors and housings needed to be replaced and now my front driver side window is down and will not roll up. On the way to work this morning it stopped working and now my car is sitting outside at work unsecured. Kia contacted me regarding my last complaint and is working to see if I can be reimbursed for the second window. I am waiting for a response now to my email and call this morning regarding this third window.

My rear driver's side window started falling down all of a sudden. I had to replace the regulator and the motor. Now, just a few months later, the passenger rear window is doing the same thing. This seems like a defect. I never had to replace a window motor in my 1997 Toyota 4runner that I just traded in in July of 2018.

The drivers side running light went out one day and my car alerted that it was out. I changed the bulb and that did not fix the problem. The fuse appeared ok, however I replaced it just to be sure. There was still no change. Checked the power to the headlight assembly and I have power all the way up until it enters the headlight assembly and then there is no power to the running light only. The entire headlight assembly had to be replaced for a whopping $360.

On the evening of May 17, I needed a jump after work. I went home, turned off my car but was unable to start it again so I replaced the battery. I thought I had fixed the problem until the next day when I was driving 65mph on a local interstate with my daughter in the car, all my dash lights came on, I lost navigation & radio and my power steering locked up. I went to turn on my hazards and those did not work either. I checked my mirrors to make sure no one was going to hit me and I was able to get off the highway and pull onto the shoulder. I was extremely fearful as I had minimal steering capability & was unable to notify other motorists of my disabled vehicle as my hazard lights were not functioning. I was able to get it towed to a dealership where I was told I needed a new alternator for my 3 year old car. While my mileage was at 66,500 miles, I definitely had not anticipated need to replace that part of a while. Despite that, I was more upset that I lost function of my car and was not able to warn other cars with working hazard lights.

As I began crossing the intersection (highway) I ended up getting T- boned halfway through the intersection by a pickup. He was speeding going roughly 60mph in a 45mph zone my Kia Optima sustained passenger side/ and frontal impact damage. The impact of the accident sent me skidding across the highway and none of my frontal airbags activated nor did the seatbelt lock up. This lead me to sustain heavy chest injuries from the impact of the steering wheel. Also the car could not be shut off after the accident. The vehicle stayed running until emt disconnected the power to it.

In August 2018 I noticed that the camera on the front grille of my 2016 Kia Optima was producing a blurry image. It did not do this the night prior when I used the camera to park in my garage (where I did not hit or bump anything, I was not even near the wall at the front of the garage). The lens had a crack. Some context: This happened before in 2017 and the Kia dealership in mcdonough, ga repaired it as a warrant item. I took the car to the dealership, where the service representative named jose camacho said they they would cover it as a warrant time and that I would not have to pay for it. They just needed to order the part and would call me when it arrived. I never received a call, so when I called the dealership in September 2018 I was told that the claim was denied as a normal wear and tear problem and that they should never have replaced it the first time. I was told that if I wanted to disputed it, I would need to call Kia Consumer Affairs. Kia Consumer Affairs told me that they would check with the dealership and after a few weeks, I called them back and they said the dealership wanted my to come back. I called the dealership and they asked for me to bring the car in so they could take pictures. While I was there I ask what the odds where that the camera lens would crack twice with no visible damage to the camera unit, the grille or the bumper, the service manager justin, told me it wasn't likely. I notified them that there was a 3 page forum on the internet where other Kia Optima owners have reported the same problem, in fact, if you do a simple google search for Kia Optima cracked lens, it is the first search result. I asked why this is not a recall item, and they shrugged there shoulders and said they didn't know why. They then said they would submit the pictures and I would get a call back from Kia Consumer Affairs. It was denied, no reason.

In had just been turned off, and was already in park and emergency brake on.

They reported the accident and it is under investigation. Murray Kia was where the car was towed. They could not replicate the problem and told me it was an insurance problem. Not true!! my passenger and I were lucky not to have rolled into the street and oncoming traffic, and could been killed or seriously injured, or injured others. Thank god the parked car was there and only then did the car crash into it, and stop.

My Optima seems to hesitate or studder when accelerating from a stop. It reminds me of a gear slipping but my car only has 11,145 mi on it so there's no way that's possible. This has been an ongoing observation for months now. I've also had one of my mirrors not go back to normal position after I moved the car from R and began to drive. I had to pull over, place the car back in R, and flip back to D for the mirror to go back to place. Lastly I've noticed my driver seat seat warmer button isn't lighting up like it used to. When on high, only 2 lights are on. I recorded a video of it vs how the passenger seat works but I don't think I can upload it. I've at least taken photos of it in each level. This has been for about 2 weeks now. Mileage listed on report is what I'm currently at but the studdering has been since 3,000mi or
