It began when we would try to start the car it seemed to have battery issues and have trouble starting, and finally the battery did drain but isn't holding charge but took it in to get checked and battery is fine. The headlights will randomly shut off while driving at night like if the sensor were in the day time. Now the engine light has came on while driving it and when you hit the gas it jerks the car after 20 mph. This happens on and off where it will be fine then suddenly start doing it all over again everything also happens in different occasions.

Sometimes when I start the car it only runs at about 500rpm and the digital speedometer starts going up in numbers when I'm in park and I have no power steering. I can put the car in drive and park or open the door and it starts acting normal. It also acts like it's going to shut off when I come to a stop. I am aware that the rpms drop when you stop almost like a gas saver but with in the last 20 thousand miles it has gotten really rough. It burns oil like crazy the dealership is aware of this but can't do anything with the engine tell it throws a code and they can't duplicate any of my other issues, the front end has made awful noises for the last 50 thousand miles or so and has had the front suspension replaced but that didn't fix the issue. Iv has the knock sensor replaced but I'm convinced it was just a gimmick so the car won't throw codes anymore because it should be with the issues I'm having. Like when the electronic steering goes out I get no dash light. I wish Kia would own up to their issues

I'll start with the windows. Prior to covid my right rear passenger window motor and regulator went out. Citrus Kia fixed it. Right after covid was announced my front right passenger window went out and I couldnt get my car in. 2 weeks later my front left driver window went out. When I finally got my car in they told me I was 200 miles over on my warranty to fix it. I havent had the use of either of my front windows for months. They dropped randomly going down the road. If I dont leave something wedged in the window they drop so far I have to use duct tape to adhere to it and pull up enough to grab it. Its definitely a safety issue that I cannot use my windows. And I dont know what is going on with the drive train, axle and suspension but I am eating through brand new tires every couple months. The dealership blamed it on me and seriously asked me if I was jumping curbs. I have had so many issues with this car since the motor got replaced. Not to mention my heat doesnt work unless its in defrost mode. The dealership knows about all these ongoing issues. Karen is my service advisor. I even tried to trade my car in with them and they turned it down. This car is falling apart and I am only one month away from having it for 4 years. I am the only owner it has had

The headlights will randomly turn themselves on and off in day and night time. This only happens in the 'auto' option for the headlights. I have seen numerous other reports on this on here. In addition to that the car doesn't respond to the key fob most of the time even with brand new battery in the fob. Step dad has the same car with same issues with the key fob.

In June 2020 after ordering food at a fast food drive through my driver side window would roll back up. I didn't think much thought maybe the window was off track. About a week or so later while driving on a local street in my town my driver side back passenger window slid down I began hearing and feeling wind come through the window I called my dad who lives in miami he told me to put a flat head screwdriver down in the window to keep the window from sliding down and possible breaking and to call the dealership. I called the Kia dealership I was told to make an appointment to have the windows looked at. (which I did) a couple days later while picking my daughter up from work I was backed into a parking spot. I rolled the back passenger side window down to let her know I was there since she was more to the back side of the car then the front and all behold the window would not go back up. I called Kia 1st thing the next morning and was told my car had a recall for the electrical but they could not do anything about my windows unless I paid out of pocket because the recall did not cover the windows. I'm upset because I do not have money to fix 3 windows had I not had that electrical problem my windows would still be working.

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.
