New Car Assessment Program
The 2025HYUNDAIKONA carries 25 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 2 crashes, 0 fires, 3 injuries, and 0 fatalities. For crash performance, NHTSA's New Car Assessment Program gave this cohort an overall 4/5 rating, with 4/5 front crash, 5/5 side crash, and 4/5 rollover scores derived from standardized barrier and dynamic tests.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2025 KONA is power train with 3 filings, followed by unknown or other (3) and electrical system (3). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability.
NHTSA currently has 37 investigation files overlapping the 2025 KONA, and 1 remain open. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

While the cruise is set, traveling on I44 with no other car in front of my Kona, the adaptive cruise control will start to flash and apply brakes immediately. The speed will drop instantly. Thankfully no other vehicle has been behind me, otherwise it would have caused a massive wreck. I have taken the Kona to the shop 5 to 6 times for this situation, but they will not do anything since they can not duplicate it. I took a video recording of it happening, and they still would not do anything. The first incident was December 31, 2024. This happens every other week when I travel out of town for my daughter parenting time with her dad.

The contact owns a 2025 Hyundai Kona. The contact stated that while upon starting the vehicle, the vehicle failed to respond as intended, and the vehicle needed to be jump-started. The vehicle was taken to a dealer to be diagnosed; however, the diagnostic result was unknown. The vehicle was not repaired. The failure had occurred on several occasions. The manufacturer was notified of the failure and informed the contact that the vehicle did not fall under the Lemon Law. The failure mileage was 12,000.

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.
Engine light was on - I was told by Belmont Enterprise on Sept 17th to keep driving the vehicle even though it needed repairs immediately.
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 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 the speed limit and/or your intended driving speed if the uphill is long enough for the speed to fully recover itself. It is not an issue with vehicle power available as I can easily maintain an exac

As part of Hyundaiâs 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 on the highway around 70 to 75 MPH and suddenly the sunroof exploded. No debris impact. Just suddenly and randomly the glass just exploded and shattered.
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.
