Engine

“I bought this vehicle less than 60 days ago and there is transmission hesitation, hard engagement in lower gears, Rough jerking shifting along with acceleration lag. Erracric shifting and phantom braking. I have taken it into the dealership I bought it at at they are not seeing anything. It currently is at another Kia dealership for the past two days. This vehicle is going to cause an accident that puts my safety and others at risk. There is no warning lights that come on. I have done my research and there has been other complaints from other consumers having the same issues. I do have video of in town driving but have not been on the highway”

“chrome pillars came off on highway. the recall was sent in mail but upon visitation to kia for a different recall, I mentioned pillars and they did not have part to repair and there was a wait for part on their end is what they said. car was literally built with many defects I don't know how it passed inspection.”
Electrical system

“Beginning only about 6 months after I purchased the vehicle, the audio system intermittently screams at me, blasting at over 800 decibels road, engine noise and audio interference noises so that I cannot hear the radio, the telephone, turn it off or down, even when the audio infotainment system is not running. The only way to keep the vehicle from doing this when it occurs is to turn off the car. The noise is so loud that I cannot hear oncoming vehicles, including emergency vehicles, nor can I use the bluetooth phone system - if necessary I would have to break the state law about holding my phone to scream into it- even if someone could hear me on the other end. If I had the windows open, the audio system would break local noise ordinances. It is almost impossible to drive the vehicle when this occurs even though the dealership has said several times that I must bring it in when it is occuring; on one occasion to fulfill this requirement, I put in my earbuds and played music to drive to them for 1 hr to drown out the sound still surpassing my ability to safely focus on the road. Having documented PTSD, ADHD and anxiety disorder, having to drive the vehicle not…”
Forward collision avoidance
4 reports1 crash
“I purchased a brand new 2024 kia k5 gt on September 2 2023; from kia of Cerritos "18201 Studebaker Rd, Cerritos, CA 90703" . My car has noticeable defects that affect the driving experience and can be dangerous. When coming to a stop the engine turns off as if it was deactivating one or more of my cylinders. While that happens it stalls the car. My adaptive cruise control doesn't work as intended since it came damaged from the manufacturer, while driving with the adaptive cruise control on the vehicle requires more input to maneuver. The vehicle did a sudden jerked and almost ran me into a freeway barricade. I also noticed some of my trim pieces and my steering wheel aren't properly put on and are falling off and the body trim is under recall. The dealer handlingthe recall is kia of downtown los angeles "1945 S Figueroa St, Los Angeles, CA 90007". I was able to fix the trim pieces by another dealer. I let the dealer I purchased the vehicle from know of the experiences I had with the vehicle and nothing was done.”

“On [XXX], while driving to campus during rush-hour traffic at approximately 15-20 MPH, the car suddenly felt as if the brakes had been slammed, giving me a serious scare and nearly causing an accident. The car stopped in the middle of the road, and I was stuck there, forced to manually push the car to the side to avoid further risk to myself and other drivers. I immediately had the vehicle towed to Ourisman Chantilly Kia for service. Upon arrival at the dealership, I requested a loaner vehicle. However, it took an entire week for one to be provided, leaving me without transportation for a significant period of time. I was informed that the dealership needed my approval to take apart the transmission, which I gave immediately. Despite this, for the next two weeks, I called daily for updates, only to be told that no new information was available and that the dealership was still waiting for guidance from Kia's technical team. After two weeks of no progress, I asked my service advisor, Sean, what had actually been done to my car. He informed me that the only action taken was draining the transmission fluid. I was baffled that it had taken two weeks just to drain…”
