2025 KIA K5 Complaints

Transmission has extremely hard shifting if vehicle sits for more than 24 hours. After the vehicle is parked, inside garage, or outside, the first drive of the day has an extremely hard shift of the transmission on the first shifting of the day. The shift it so hard, it jerks the entire car and jolts me in my seat. The remainder of the drive and day, the hard shifting does not occur. Took the vehicle into dealership where purchased at 1000 miles and left it with them for 2 full days. Unsurprisingly, they said they were, "Unable to reproduce". The next day, the vehicle had the exact same problem. I have close to 3000 miles on the vehicle and the transmission continues to do the exact same thing every time I drive it. It is terrible for a brand new car. It doesn't matter which "Drive mode" the vehicle is in. The dealership also tried to reset the ECM. But no luck. My neck and back have been sore from the hard shift events too.

234/45/R18 - 94V bubble developed on exterior of front, passenger side tire AND the interior of back, passenger side tire within a year of purchasing vehicle new with this tire installed. The tire had to be replaced immediately to avoid a tire blowout.

OEM Pirelli tire blew out going 55mph. The car has 6500 miles on it. The sidewall of the tire blew. There were no punctures in the tire or reasoning for this to happen.

Third time that this happened when I step on the gas you're accelerate the transmission wines when I'm trying to merge I have to slow the car down and take my foot off the accelerator and then when I put my foot on the celebrator there's a car really close to me

I am the owner of a 2025 Kia K5 GT-Line that was recently involved in an accident. In the days prior to the crash, I experienced recurring issues including screen reboots while driving and temporary power loss. I do not remember the moment of the accident, and I am currently under medical care for head trauma. I am reporting this because I believe the vehicle may have malfunctioned in a way that contributed to the accident. Please advise if there are known issues with the 2025 K5 GT-Line, and how I can formally report this case for technical investigation.

Tire pressure light did not illuminate. Tire was apparently low, and tire blew out at stop. Inside sidewall of tire had large gash once tire was removed and spare installed. See picture.

I am reporting a safety concern with the KIA K5 Advance Driving Assistance Systems. The concern is the Driver Attention Warning (DAW) being a distraction to the driver due to consistent dinging and flashing light of the "taking a break" that according to manual could go off every 4 minutes, however, in my experience it can go off every 3 minutes (see attached documentation), which is excessive. The frequency that the light goes off has led me to be distracted and nearly hitting the car in front of me because I am looking down at the light. I'm at the point; I am afraid to drive the car because I don't know when this light will go off. According to the manual it can go off 4 minutes into a drive. When reviewing the manual, it fails to tell you what exactly is causes the light to go off and how long you are supposed to be taking a break for. I have taken it to the dealership three times, and they tell me it is working property. I have asked if the light can be shut off, but they tell me it cannot be shut off even though it says in the manual it can be. I have also worked with KIA corporate, and they tell me the newer KIAs it cannot be shut off. The older models also had attention level gauge that could show the driver where their attention level is, but this was removed. In conclusion, this "take a break light" is a major distraction to driver that cannot be shut off that could lead the driver taking their eyes off the road multiple times in a driver that can cause an accident.
