general problems of the 2025 Hyundai Kona

The vehicle experienced a total electrical failure while driving. Dealer diagnosed the issue as a loose fuse box connector/power distribution connector. The vehicle and repaired component should be available for inspection through the Hyundai dealer service department. The vehicle suddenly lost all power while being driven on a public roadway. The engine shut off, dashboard went dark, and power steering assistance was lost, creating a risk of collision and leaving the vehicle disabled in traffic. A Hyundai dealer diagnosed and confirmed that a loose fuse box connector caused the loss of power. The vehicle was inspected by an authorized Hyundai dealer service department. No police or insurance inspection was performed. No warning lights, messages, or symptoms appeared prior to the failure. The vehicle lost power suddenly without warning while driving.

I have a 2025 Hyundai Kona limited. On [xxx], around the afternoon on sunnyvale, California, while exiting [xxx] headed to lake tahoe, the liftgate bolt that attaches to the body had buckled mechanically as the system did not back away when a flashlight that came out of a travel bag was blocking the way to have it closed. The car computer thinks the liftgate is open even though the lock is secured. The car computer allows to drive without seatbelts secured or closures ajar for a few seconds at low speed but then it automatically with little warning engages the electronic handbrake while driving. I was driving on a highway in a middle lane when the car engaged without my consent the electronic handbrake locking the wheels and I almost got rear ended and killed by a semitruck. I had to floor the gas pedal and steer to a shoulder to request a tow. Since it was a long weekend before presidents day, I had the car taken to the nearest dealer in modesto California. Their service department invented a lie that due to a side crash, which was a failure of the collision mitigation system that happened months ago, is the cause and that it is my fault even though the driver admitted responsibility but it is an unrelated issue. There should be a way of overriding the car computer so it does not engage the electronic hand brake on the middle of the highway, specially at night as this creates a road hazard that can lead to death. I replicate the issue with a rental, a Hyundai tucson, they use the same gas strut and bolt that in my opinion has a very narrow gage. As you can see in the picture, the passenger side bolt is fine, the driver side is buckled. The side accident that happened on may 2025 was on the passenger side but the liftgate is fine; at any rate both sides should be deformed not just one if that were to be the case but it is not. Dealer and Hyundai attempting to sideline the issue to avoid a warranty and recall in my opinion. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

This is second time all electrical has gone dead in the car. First time I took car in for an update and now something is still draining the battery. I have read multiple posts online of this issue. The car has less than 5000 mile on it.

The embedded navigation system tends to provide directions getting the vehicle into off road areas that are not designated to be driven. This not only causes damages to the car but also leads to unsafe situations. While driving in the upper peninsula of michigan headed to the kitch-iti-kipi, it took me to tall grass and high voltage towers almost getting me to a ditch. While driving in st. Augustine beach, it almost took me to the ocean. While driving near lubbock texas around a detour due to construction, it almost took me to a cliff.

As part of Hyundai’s driver attention warning system, it plays a loud beeping noise that disables other systems in the car (map, audio). This beeping noise plays at random times and has been heavily distracting on long drives almost causing me to crash due to issues with my hearing and the frequency of the noise. It cannot be disabled. I would be happy to present the vehicle for inspection. The dealership and manufacturer have not responded to calls or have given unsatisfactory feedback as to solutions. This alarm has gone off about three times within the past 10 minutes and I am struggling to drive long distances with it on. Any help please.

I was driving at 930pm in the dark at a speed of 30 mph and the car completely shut off all power. No warning signs. Just completely lost power. No headlights or interior lights. I was able to brake and stop the car and restarted it to continue on. Lu ckily I was on neighborhood roads with street lights and little traffic. This could have been extremely dangerous on a road with no lighting and a high speed. I am now scared to let my new teen driver use this car and we bought the car for her! the car was at 47 percent battery and only has 5000 miles on it. Seems in my current research this is somewhat common for Hyundai. Please make them fix this before someone is seriously injured!.

A week after I got my 2025 Hyundai Kona limited, while trying to have the moonroof when headed into the highway since it gets too noisy if left open, the glass will touch the guard and then back away and remain fully open. However, the issue becomes more serious when it starts to rain or snow as it will remain open. In three occasions, the moonroof will not close. During a downpour, I had to use a large umbrella to avoid water to flood the car. Had I not had an umbrella or something to prevent water from getting in, the vehicle electronics could have become damaged including my personal belongings including but not limited to my sensitive medical equipment. Had I been in a snow shower, I will have gotten sick with a cold. I had reported the issue several times to different dealers and they only say it needs to be cleaned and reset. I had a sonata with the same moonroof for over three years and I never experienced such an issue.
