UNKNOWN OR OTHER, ELECTRICAL SYSTEM:HORN
The horn for this vehicle simply stopped working. The horn was used earlier in the day to prevent a different vehicle from changing lanes to avoid an accident. My wife has the same vehicle (year make and model) and her horn stopped working 2 weeks ago. The fuse is not the issue on either vehicle. My wife was informed by local Kia that this issue has been common. I researched this issue online and several Kia customers have experienced the same issue. This does not seem coincidental, and poses a great safety concern! Customers should not have to front the cost for this as it seems to be a defect in the manufactured line.

AIR BAGS
While on her way from work, my mother was involved in an accident in her 2021 Kia K5 LXS where she was rear ended at a high speed by a driver not paying attention to the road and she ended up hitting the car in front of her. During the accident NONE OF THE AIRBAGS DEVELOPED. My mother was hospitalized for a month and do to the SEVERITY OF HER MAJOR INJURIES (rib fractures, a closed fracture of her T7-T8 with loss of sensation and mobility of lower half of body) she passed away from “Effects Of Blunt Spinal And Rib Cage Trauma.” No recalls were noted for this particular model and year until March of 2023 which was way too late.

SERVICE BRAKES
My vehicle is a 2021 Kia K5 GT (2.5L-T), mechanically identical to Hyundai Sonata N-Line (2.5L-T). My car has 24000 miles on it and I have replaced the rotors on my car five times now due to premature warping. KIA OEM rotors, R1 Concepts, Brakenetic Rotors, all have warped. This issue is discussed amongst GT and N-Line owners heavily in the forums stating how the OEM Brake system has some sort of issue that causes premature rotor warp. Some have even resorted to changing their brake system to a old model Cadillac CTS-V system because of how crap these brakes are. Again after less than 2 months with new rotors, they have warped yet again.

ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS
Vehicle will occasionally fail to properly initialize its safety systems, causing ABS, Traction Control, FCW, warning, auto stop, auto hold lights to come on and the aforementioned systems to fail. This disables driver assist features and important safety systems. Kia Dealer does not attempt to resolve. Claims that “we parked too close to a tree and the vehicle thinks it was in an accident” would like further investigation from Kia to be performed regarding this issue.

LANE DEPARTURE, FORWARD COLLISION AVOIDANCE, ELECTRICAL SYSTEM
The contact owns a 2021 Kia K5. The contact stated that while driving at various speeds, the Lane Assist feature would illuminate without other vehicles nearby. The contact also stated that the vehicle would independently switch lanes independently; causing the contact to forcefully adjust the steering wheel into the desired lane to prevent a potential crash. The contact manually disabled the features; however, the features independently reactivated. In addition, the defroster failed to operate as needed which obstructed her vision due to fog on the windshield. The vehicle was initially taken to a dealer, but the contact was offered no assistance. The contact then took the vehicle to Kia of Irvine (45 Oldfield Building B, Irvine, CA 92618) where two mechanics acknowledged the failure while test driving the vehicle. The contact was assured by the dealer that both safety features where disabled; however, within minutes of leaving the dealer; the features independently reactivated. The manufacturer was notified of the failure and the contact was given a case number. The vehicle had yet to be repaired. The failure mileage was 17,951. The consumer called to make an appt due to the check engine light illuminating and informed vehicle will not be repaired for a few weeks. In the meantime the gas smell is pouring through the vents.

POWER TRAIN
My vehicle has been experiencing shifting delays when accelerating. Often times when I stop accelerating my vehicle has a delay and remains revved up for a few seconds before the RPM's go back down. The sluggish/delayed acceleration presents a safety issue when the vehicle is not operating as it should. This issue has been occurring for about 6 months. I informed the dealership where I purchased the vehicle and have the routine maintenance done and they say there are no issues reported about the issues I have been having. I addressed the issue again over the weekend when I had my oil change and tire rotation on April 1, 2023 and I have been told the same thing that there are no issues reported. But the dealership fails to report the issue I had addressed the first time.

ENGINE, FUEL/PROPULSION SYSTEM, UNKNOWN OR OTHER
One day I was driving my car when suddenly I heard a loud explosion sound from the back. I continued to drive the car until I could pull over to inspect the car. In the midst of pulling the car over I began smelling a strong odor of gas in the cabin of the car. Prior to stopping the car started skipping and missing badly. I pulled over checked the car and discovered something malfunctioned and caused the rear seat to pop up and be bent from the frame. I proceeded to look under the seat and saw where what appeared to be the fuel pump almost popped out, the bracket above the fuel pump was broken and popped up from the explosion, the seat would not go back in place. I looked at the gas hand I went from 3/4 tank of gas to E in less than a few miles. The exhaust also sounds like something blew or came apart the car runs very loud and you can hear the car sounding like the exhaust have a hole. After the sequence of events the engine light never came on. This is huge life safety problem that should have never happened.

1. Car has completely lost power during normal driving. Transmission failure. Loss of Motive power. It is available for inspection upon request 2. Car lost all motive power while on the highway, car had to coast to a stop. This was very dangerous. 3. Car was taken to the Kia dealership, diagnosed by their techs, and transmission replaced. This has occurred two times since the car was purchased new. First at 4,600 miles (6/13/2021) , second at 16,600 miles (9/7/2022). Both times dealership replaced the transmission 4. Both times this occurred the check engine light illuminated and a warning to pull over immediately. There were no prior symptoms when this occurred. The failures happen suddenly. There is apparently already a recall for this issue for the Hyundai vehicles that have this very same engine/DCT combination. Recall #236. This same issue is also occurring on the 2021+ Kia Sorento and 2021+ K5 GT 2.5L
