While slowing down from highway speed during hot weather, the front passenger door suddenly became unlatched and partially opened. A warning alert sounded, and I had to pull the door closed. There were no prior warnings or symptoms, and the dealer has not been able to reproduce the issue.

Component or System: The brake system, specifically what appears to be a false ABS activation or IEB (Integrated Electronic Brake) system malfunction. The component is available for inspection upon request. Safety Risk: While braking at speeds between 25-40 mph, typically on dry pavement and more frequently on downhill grades, the brake pedal exhibits a chugging sensation, erratic stopping behavior, and pedal softening consistent with unintended ABS activation or IEB malfunction. This occurs on dry roads where ABS activation is neither warranted nor expected, creating unpredictable braking response and extended stopping distances. The defect has occurred 24 documented times since [XXX], and existed prior to that date. Dealer Confirmation: Yes. During a ride-along at Edmond Hyundai on [XXX]
My forward collision warning activates without cause. My automatic braking systems will engage.
electrical 4 complaints shown
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
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.
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 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.

I was driving down my street (one way) at 20mph when all of a sudden, the car veered to the left and smashed into a dumpster that was parked on the street. I had driven down my block several times during the day and was aware of the dumpster. I am convinced that the lane assist malfunctioned and drove into the side of the dumpster. I was not distracted and my brand new, 2025 Hyundai Kona was totaled in the accident. I had minor injuries but could have been much worse. I am not sure who to contact to report this and not sure it could be proven. Any help you can give me I will appreciate.

Engine light was on - I was told by Belmont Enterprise on Sept 17th to keep driving the vehicle even though it needed repairs immediately.
cruise control 1 complaint shown
The cruise control operation is unusual and the speed can vary greatly while it's engaged in moderately hilly terrain (not extreme) on the interstate ([XXX] through Kentucky and Tennessee). With the cruise set at interstate speeds and starting to climb a hill, the speed can drop by as much as 6mph below set point as the cruise control very, very slowly starts to increase throttle to compensate for the grade. Eventually it will stop the deceleration at that up to 6mph speed below the set point, before slowly starting to accelerate back up to the set point. One instance I timed was 22 seconds between the speed first falling below the set point, down to 6mph below, before recovering back to the set point. Sometimes it overshoots the set point by 2mph, meaning it could cause you to exceed
brakes 1 complaint shown
Mushy brake pedal after 1000 miles This just started yesterday, seemingly out of nowhere. When I push the brake pedal it's mushier than it used to be. If I push hard, I get more resistance at first but then it slowly sinks toward the floor as a I continue to press. If I push softer then it just sinks toward the floor. I still have plenty of stopping power. If I push the pedal repeatedly then it builds up more resistance ("pump the brakes") but then the resistance calms down and it becomes mushy again.
