2026 Hyundai Kona Speed Control & Cruise Problems

I bought the car in November 2025. I was on a highway, going at a comfortable, 65 mph speed (a few weeks after purchasing this happened the first time ). Suddenly, the car stopped accelerating, of course I panicked, slowly pulled off to the shoulder, and shut the car off. Luckily, it was not rush hour . I restarted the car, and it was normal driving. I texted my salesperson and asked if he had heard about this issue. He said no. No warning lights or messages appeared as that happened. The speed had decreased and stayed at 36 mph for a few seconds. A few weeks later, it happened again, this time it stayed at around 36 mph. I pulled over and shut the car off, restarted, and no issues. This time I told my salesperson I wanted to bring it in, but they had a one-month wait and offered no help, didn't seem phased or concerned. I took the appointment for February 17, which was approximately a 4-week wait. Again, no lights or warning signals. The third time this happened I was merging on to a very busy ramp to enter a busy highway, and the speed stopped at 11 mph, and I panicked, pulled over restarted the car and that was enough for me to call and insist they take the car as soon as possible, as we were expecting a major snowstorm which did happen the next day. I did not take the car out and brought it in to the dealer on Monday. Again, they seemed unconcerned but took the car after I insisted. The car has been there for 2-weeks now and they claim they cannot find a problem. I called Hyundai corporate. After investigating, they too said there was nothing they could do since they could not find a problem. I may add that while this is happening I am stepping on the gas and nothing happens.
