The vehicle throws a forward collision warning and then suddenly brakes to slow down while driving with no road hazard in front. This occurs about once every 10 days. This is a safety hazard because the forward collision warning has to be turned off every time the car is turned on. It will not stay off. During sudden braking, an accident may occur behind the vehicle. We have left the car at the dealer for 3 days while paying for a rental car and they said they could not reproduce the error. I have contacted KIA through their website about a week ago and have received no response. I have video evidence of this problem occuring on dashcam.

I have an issue that involves the metal railings in the center of the vehicle (on the floor) to get hot enough to burn and blister you. I filed a complaint with Kia which opened a case. I also took my vehicle in and this issue was verified by their mechanic. I was assigned a case number and after the employee on my case spoke with the enginer team it was determined that the only option for me was to purchase mats to cover the metal railings. I purchased both all weather and fabric mats when i purchased the vehicle. these mats do not cover the railing nor would you want them to. it would prevent the seats from moving forward and back and it would also be a fire risk. I have tried to find a solution with kia with no success. There are other forums of people complaining of the same issue such as this one https:// [XXX] I just purchased my car brand new and Kia has put me in a position to just deal with these safety issues. Besides mats that i already have the suggestion was to just not touch the rails that are on the floor where you put your feet. I put 10,000 down on a brand-new vehicle because i had the intentions of keeping it long term. now im in a position where I have to look for a safer vehicle with no help from KIA. This complaint may not help me but maybe it can help someone else. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Purchased in Aug 2022 brand new I express concern very early on that the back door would reopen after starting the car I express concern about shifting/breaking being automatic/ice light coming on when you hit bumps coming in parking lots and the doors not unlocking. All were evaluated and basically all for nothing “ could not be duplicated” I called, left voicemails, emailed the dealership with concerns Advised there was a recall on Back door which was one of my complaints did recall update still and issue The back door should not re open and stay open that is not a safety feature this day and age it’s asking to be mug, robbed ect. After the 3rd time in a week happening I called the dealership spoke to the president and advised I no longer felt safe I just want to turn in the lease have it bought back and my down payment returned. I have 3 children safety features they claim are not safe in my eyes. One example driving by myself out of a parking lot the back door reopened as I was backing out and I assumed it would just reshut - no it stayed wide open. No movement. No unlocking, turning off after auto start under a few mins. I called Kia and have yet to speak to the agent, phone tag, no emails back. Reviews online show multiple people have these issues.

Unknown. My vehicle has cut off in the middle of traffic several times. Another incident was when my vehicle was shaking uncontrollably and couldn't go over 40. The check engine light never comes on. One dealership looked at it and said nothing was wrong even though one of the techs heard the vehicle. They said because the check engine light wasn't on that there was nothing that they could do. Took it to the kia dealership in Huntsville. They know something is wrong but because no check engine light or codes. They don't know where the problem is . My main issue is when something is wrong. No lights or codes show up. I haven't had it a year yet. Safety concerns with it cutting off in the middle of traffic .

The side sliding (rear) doors do not stop when there is an object in between. Even when you put heavy force (this is in some angles), the door continues to close. With mild force, the door just refuses to recognize and closes out. It is a big safety concern with small children, since if the force applied by adults is not enough,…

The side sliding (rear) doors do not stop when there is an object in between. Even when you put heavy force (this is in some angles), the door continues to close. With mild force, the door just refuses to recognize and closes out. It is a big safety concern with small children, since if the force applied by adults is not enough, then any force the child would apply is definitely not going to stop the door from closing.
