2024 Hyundai Kona problems

Filed Oct 20, 2026 · Brakes · MA

I purchased a new 2024 Hyundai Kona in September 2023 and followed its scheduled maintenance program. By August 12, 2026, I had noticed mild, intermittent excessive brake-pedal travel, especially at low speeds. I reported it to the dealer that day; September 14 was their earliest available appointment. By September 14, the pedal drop was more pronounced and frequent at low speeds. The dealer inspected the brakes and reported no abnormality. A technician verbally acknowledged some downward pedal movement but reportedly considered it acceptable. No cause was identified or repair made. By September 16, the problem had become persistent and severe: approximately the first 90% of pedal travel produced little or no effective braking, with limited braking only near the floor. Stopping even at very low speeds became difficult. Sounds and pedal feedback suggested frequent ABS activation, although this was not diagnostically confirmed. I stopped driving on September 16; the vehicle has remained parked and is available for inspection. I first reported this severe condition to Hyundai Motor America on September 16 because I had lost confidence in the original dealer's handling of the problem. More than a month later, Hyundai has offered no clear corrective plan, instead referring me back to the dealer for another inspection. I am willing to have the vehicle inspected by another authorized dealer, or even the original dealer if Hyundai directly coordinates a defined diagnostic and repair plan, rather than leaving me to negotiate it myself. This serious braking problem arose in a roughly three-year-old, regularly maintained vehicle, was reported before its third anniversary, and remains undiagnosed and unrepaired despite dealer and manufacturer notification. I request the federal safety agency review this potential brake-system safety defect and the associated collision risk.

This mainly concerns the forward collision detection sensor, if that’s even what it’s actually called. My vehicle is available for testing and inspection. I was driving on an interstate, with my adaptive cruise control set to 75 mph. I was in the left of 3 lanes when got to a curve that went to the right. As I came to the beginning of the curve, all of a sudden my dash is warning me of a forward collision and the car started braking hard on its own. There is a metal guardrail that separates the 2 sides of the interstate and cars are also coming from the other direction. There wasn’t anyone behind me, thank goodness. If there had been, I can’t say for sure what would have happened, but it would not have been good. It took a hot minute for me to figure out what it was doing so I could stop it and get back up to speed. It scared me when it happened. When I go the same way without my cruise control on, it doesn’t happen. That’s how I know it has something to do with how it’s all connected. This has happened twice at 2 different places since I got the car in May of 2024. I don’t use my cruise control hardly at all now because I’m scared it’s going to suddenly brake again. I wasn’t sure what could be done about it. I put the info on the Hyundai owner surveys but nothing ever happened. I found the federal safety agency completely by accident. I want someone to inspect it and try to recreate it, but it’s an awfully dangerous thing to try. Nobody has yet. It’s not like it’s a noise or a rattle. The only thing that I would consider a warning was the crash detection warning on the dash screen that flashes red. That started right about the time that the brakes were activated.

Consider taking a coffee break distracts driver. This issue warrants immediate consideration for a recall. Anytime I drive, this warning keeps going off shortly after going on a windy or pothole filled road (all of PA). Despite driving safely and normally, the problem persists. This occurs regardless of the time of day, weather conditions, or whether I am sitting upright or reclining. The warning randomly activates and deactivates, sometimes without any intervention. Occasionally, I simply allow the warning to sound without taking any action, and it remains active for a few seconds or until it triggers a warning that the system will be turned off, at which point it deactivates. I have attempted various troubleshooting methods, such as keeping my eyes open, adjusting my seating position, wearing and removing my glasses, and tilting them to minimize glare. None of these methods have proven effective in preventing the warning from activating or in making it deactivate. This is a persistent problem. Hyundai dealerships initially informed me that the warning might be an annoyance and their response was to simply refrain from using it. However, if a basic feature like cruise control in a 2024 & 2025 model is rendered unusable due to a design flaw (which this certainly is), it constitutes a clear violation of safety standards and should be addressed through a recall. The incessant alerts are highly disruptive and can be quite frustrating. For instance, driving with an arm in the 12 o’clock position triggers a warning, while wearing polarized sunglasses also results in an alert. The presence of a setting to disable the warning is a welcome feature, but the system’s persistent alerts can be overwhelming. The alerts continue even after taking a break. It is distracting and a safety hazard. Drivers should be able to adjust the sensitivity of the feature or turn it off all together.
