2025 Hyundai Kona Problems

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.

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.

The dash will completely go black except for red words *no signal.* and all warnings are no longer visible, I cannot tell what speed I’m going, or what percentage battery my car is at. I don’t see visible lane or collision warnings. It is very unsafe and I have been to the dealership twice to try and fix it. The issue returned both times.

My forward collision warning activates without cause. My automatic braking systems will engage.

I purchased a used Hyndai Kona with 26,000 miles April 30 2026. I was told I have the balance of the manufacturer warranty of 5 years or 60,000 miles. I have not driven my car for 73 days because of extreme safety problems the Hyundai Kona. The car is very difficult to steer. The car pulls significantly to the right. One day after I purchased this vehicle the car jumped the curb and my face hit the steering wheel cutting my nose and creating a black eye. There is a lot of play in the steering wheel. When accelerating from a stop the car hesitates to move creating a safety concern. My rear view mirror does not stay in place. The mirror drops down and I cannot see behind me causing a safety concern. Both side view mirrors have to be adjusted each time I drive the car.

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], a technician directly witnessed and confirmed the occurrence. Despite this confirmation, it was not documented on the repair order. Two prior repair attempts returned cannot-reproduce results: March 2, 2026 at Bob Howard Hyundai and March 10, 2026 at Edmond Hyundai. Additional Repair/Inspection Attempts: On April 7, 2026, Norman Hyundai opened and closed a repair order without the consumer's knowledge and refused to provide a copy despite an explicit request. On May 23, 2026, a scheduled appointment at Bob Howard Hyundai was missed; a reschedule request was subsequently ignored by the dealership. HMA Case No. [XXX] is active. Warning Lamps or Prior Symptoms: No warning lamps have illuminated. The defect presents exclusively as a physical sensation—pedal/brake chugging, softening, and erratic stopping during normal dry-pavement braking. The issue has been present since delivery on [XXX].

The contact owns a 2025 Hyundai Kona. The contact stated that upon entering the vehicle, the front driver's side seat independently ejected the contact forward into the steering wheel. No warning lights were illuminated. The vehicle was taken to a local dealer; however, the failure was unidentified. The vehicle was not repaired. The contact sustained injuries to her back; however, no medical attention was sought. The manufacturer was made aware of the failure. The failure mileage was approximately 385.

The contact rented a 2025 Hyundai Kona. The contact stated while driving 70 MPH, the driver's side front door independently unlatched and opened. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The Enterprise Car Rental Agency was made aware of the failure. The manufacturer was not made aware of the failure. The failure mileage was approximately 14,000.

The plastic covers such as the wheel wells, inner fender linings, under body shield, are very prone to coming off by either minor objects intruding them or hitting them such as branches, rocks, or even water and sand. While driving on a highway at the Upper Peninsula in Michigan on October, a large branch on the road got inside the front wheel well and it took it away. It flew into the highway as debris and cars began evading them. I had to replace it at my expense and it come off again while driving on sand on a beach in St. Augustine Florida on December (the car is 4x4 off-road capable and sold as such). The underbody shield began coming off in a highway in near Austin Texas around a construction zone where loose gravel was present. Almost all plastic clips were missing after I was informed by a driver that plastic parts were coming off my car striking his vehicle. The wheel well of the driver side also began to come off. I had to zip-tie it; no holes were damaged but it was fully scratch and cracked in multiple locations from touching the pavement. I was hit on the side of the rear of the passenger side door and the plastic cover came off. I replaced it but it seems those plastic parts are superimposed and not well secured into the body of the car and can come off fairly easily during driving becoming road hazards that can result in a crash to vehicles driving from behind or even people or animals. I had a Sonata and the same under shield came off while driving to Miami on December 2024, their service department only had it cut leaving the underbody exposed.

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.

The contact owned a 2025 Hyundai Kona. The contact stated that while driving at an undisclosed speed through an intersection, the vehicle collided with another vehicle that was towing a trailer. The contact stated that during the crash, the driver's air bag, located in the steering wheel, deployed; however, the air bag became inoperable and deflated. The contact further stated that smoke emitted from the deployed air bag and entered the passenger compartment of the vehicle. A police report was filed. No injuries were sustained, and no medical treatment was required. The vehicle was towed by the insurance company and was deemed a total loss. The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure, and a case was opened. The failure mileage was approximately 5,000.

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.
