2025 Hyundai Kona problems

Filed Nov 3, 2026 · Seats · CA

New 2025 Hyundai Kona purchased in Aug 2025. After driving long distances, about 75 miles - 400 miles, I would experience left shoulder discomfort & constant pain in upper left arm. The bolsters of driver seat protrude & the driver needs to hunch forward. Also, the head rests do not pivot forward or back, leaving body position hunched forward as well as head & neck pushed forward. At times, I would have to hold the left assist grab bar with my left hand to avoid resting my left upper arm against the bolster in order to mitigate the pain somewhat. After 2-3 months, I made appointment with primary care doctor to assess the shoulder pain. Doctor prescribed x-ray & physical therapy, both completed & suggested buying new car with different seats or getting the seat modified. I reported my experience & complaint to Hyundai Headquarters. Information was noted by complaint intake person. Beginning mid-Dec 2025, & for the following 7 months, I lived out of state & did not drive the 2025 Kona. During that time, the shoulder pain & upper arm pain resolved. Now that I've returned to CA & driving the Kona, I use a foam square for the seat (raising me from bucket) & (2) car seat cushions (to push my back forward away from bolsters). This helps somewhat but the problem is still present. And the head rest still does not adjust leaving me to incline my head & neck forward yet not as much as previously since the (2) car seat cushions behind my back provide a bit of distance away from the head rest. I do not think the new bucket seat style with enlarged bolsters & fixed headrest are ergonomically appropriate for drivers over [XXX] of age. I did not take the name of the gentleman at headquarters of the Hyundai Complaint Division, nor do I remember the exact date we spoke.

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.

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.

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.
