These symptoms appeared recently at approximately 107,000 miles. Then when i checked the car it vanished, no error on dashboard ,so i took the car back and was driving error showed up at 109k miles again They asked to repair the vehicle and the repair is not in my budget and i told them that its the recall related issue and they are denying and saying recall was done and they dont open recall again and I found in the document they provided they just did the fuse replacement not HCA unit and The fuse swap did help with the hca corrosion and its not in drivable state and it becae a fire hazard.

This is a hybrid vehicle. It has Dual clutch transmission. Since I have owned it, intermittently the clutch does not disengage completely. This causes the vehicle to try to pull ahead but my foot is on the brake. The vehicle does not stall. Somehow it figures out it can't pull ahead and somehow fully releases. I have brought it to kia at least 3 times. In each case they tell me they cNt get the car to fail and since there are no codes produced they can't fix it. They even held onto the car several days. I asked them to please replace SOMETHING but the say Kia policy will not allow them to do that. So I am stuck with a car that keeps misbehaving. It is embarrassing because problems occur while a passenger is in the car and it seems to them that I am not driving correctly. I don't know what to do.

Driving VA Interstate 64. Traveling right side travel lane approximately 70 mph. Had ADAS engaged. Car entering highway, moved to center travel lane to pass. As I approached entering highway car, suddenly, my car stalled, engine off and I was stopped in center travel lane. Able to start car by putting transmission in park and pressing start button. Called KIA Car Care Center - They have no record of this type situation occurring throughout country. Took car to dealer. Their Technology Service Rep checked whole system and found no problems including memory bank listing the stall/stoppage incident. I will go to dealer and ask for their report. 2nd incident. Happened within first month or ownership 10/23. I dismissed incident as something I must have done due to my lack of familiarity with new technology.

This May of been a cause of a defective Harness Assembly that has taken a few tries to get repaired (Harness is fixed but problem still continues randomly). Since then, my car has stalling problems, randomly, sometimes multiple time in one drive. I have no way to replicate it on my own just that it "can happen" anytime and has subjected me to waiting on the side of the road for the engine computer to "reset" or needs for a tow. Ive been in the dealership at least twice for this with a 3rd this week. Me and the dealer thought it may go away with the new harness installed but it still remains

My wife was in an accident on [XXX] around [XXX] at the intersection of [XXX] . She had exchanged safety information with the person whose vehicle had stalled. She went to shut off the car upon exchanging the information and after pressing the ignition button the vehicle began to roll. She was outside of the vehicle when she had pressed the ignition button. She tried physically to stop the vehicle, trippped and was dragged until the vehicle came to a stop after running over her leg and hitting a tree. The vehicle had recall items addressed on October 2 or 3rd. She was trying to stop the vehicle from rolling as she knew that school was letting out and a school bus would be coming on the road she was at. I contacted the dealer about it and they stated that they had never heard of this happening with there vehicles and to call customer service. The police officer verified verbally that the vehicle was in park when he checked on the condition of my wife who sustained serious injuries on her left leg and was hospitalized for surgery and wound treatment. This is the first time that we ever had an issue with the vehicle. It started when the vehicle in front of her had stalled and backed into her (although his story changed after the injury to my wife).
