2022 Hyundai Kona

I have had my horn replaced three separate times at my local Hyundai dealership. It recently passed the NC vehicle inspection, but the horn failed the third time sometime after that inspection in Feb-2025. I have never had a horn EVER fail on ANY car I have owned for the past 50 years. A horn is a critical safety necessity and it is expected to work - especially in times of emergency. I was almost run off the highway, once by a semi-trailer and each time I discovered my horn had failed - it was due to my needing to use it to alert pedestrians or other motor vehicles to avoid accidents. The dealer would not reveal WHY this has failed three times except to state that they 'replaced the horn'. The dealer is the only one to have attempted an examination, diagnosis and supposed repair for this problem. There are no warning lights or other type of notification that would let me know of a horn failure. The only way to know that it had failed - was my immediate need to employ the use of the horn in an emergency - and it's silence aka malfunction at the worst possible times.

On February 3rd 2025, directly after putting my Kona in park, I felt it pulsing, saw the RPM dial bouncing repeatedly up and down, and the overhead lights flickering in rhythm with the vibrating/pulsing and RPM dial bounces. I recorded this incident, then turned my car off and on again at which point these observations could not be repeated - in other words, the car was acting fine. There were no other observable issues until March 1st, 2025, when these exact symptoms emerged under different circumstances. I came to an idle at a red light (with the auto-start/stop feature turned off for this drive) when the RPM bouncing, car pulsing back and forth, and lights flickering happened again. My car felt as though it was about to stall this time until, thankfully, the light turned green and I could accelerate. The issues dissipated with acceleration. I have this incident on video as well. I have a little over 63K miles on this car. I drive all day for my job, so it's used often for short trips throughout the city.

Car will stop running and not start back up when stopped at a light or stop sign sometimes. I have started driving with the auto start stop off because I will be stuck at a light or stop sign because it will power off but not come back on again. This has occurred several times. The dealership told me there was no issue 11/22/24 but were willing to sell me another battery if I wanted to just replace the battery. The battery would test fine and then not and then fine again. I did price battery’s and they tested my battery at auto zone when pricing them and it tested fine with them also. They did not feel like it was a battery issue. I don’t either now since it stays on no problem when I turn off the auto start stop. There is something honestly wrong because if I leave that feature on, it will power off and sometimes stay off. The first times it happened was in November 2024 but it keeps happening. Sometimes i forget to click off the auto start stop and it will happen to me again but I shouldn’t have to turn that feature off to prevent my car from shutting down and not restarting when stopped.

The vehicle has lose of acceleration while driving.. On Freeway the gas pedal loses acceleration. Lift off gas it accelerates then loses acceleration again. (4 times in a row) It was a big safety issue. There was no where to pull off. I made it to the nearest exit and took backroads home. Took it to Dealership they couldn't replicate the issue. I contacted Hyundai and they had the car sent back to dealership and so far they can't replicate it. It has done this numerous times, at different times and speeds. The car is now at the dealership for the second time (since the 17 of December) There were NO WARNING LIGHTS so dealership says hard to diagnose the issues.

On 10/4/2024 I was driving my 2022 Hyundai Kona SEL (61, 492 miles on odometer) with a cruise control set at 75 mph for my morning commute into work. I was approx 15 miles away from my house and at least 7 miles away from my place of employement. Suddenly and without warning the engine revved to beyond 4500 RPM and shut off. The lights on the dashboard all lit up and a message flashed on the screen stating engine cut off, turn off car and restart. I was surrounded by several cars at this time. I was able to navigate to the shoulder of the 2 lane road I was on and bring the car to a stop. When I tried to turn the car back on it would not. I had the car towed to the dealership. First they had to replace the battery as they stated there was not even enough juice in the battery to update the onboard computer for diagnostic. Then, after a week of waiting, I called and was informed that the engine was deak (advisor used the phrase "the engine when clunck"). As of today, 11/12/2024, I do not have a full diagnosis for the engine failure as the dealership has yet to inform me even though I have submitted multiple requests through various means. Service advisors states that the engine will be covered under the CPO warranty. At the time of the incident, the engine had not given any indications of any issues (like noices, stalls, etc). My sister had driven the car two days before and said it was driving fine. I had had the oil changed a week before and the tech did an inspection at that time and all parts were in working/good condition.

On four separate occasions now, I have been driving on the highway at roughly 60 mph, no cars in front of or beside me, and nothing else obstructing the roadway, when completely out of nowhere the emergency braking activates for 3-5 seconds. Thankfully there was only a car behind me on one occasion, and they were far enough behind to not collide after my sudden braking.

The contact owns a 2022 Hyundai Kona. The contact stated while driving at an undisclosed speed, the sunroof fractured without impact. The contact stated that the fractured glass fell onto the contact while driving. The vehicle was taken to the dealer where it was diagnosed with a defective sunroof glass. The contact was informed that the sunroof needed to be replaced. The vehicle was not repaired. The contact was informed that the sunroof glass needed to be ordered, and there was a 10-day waiting period before the parts would be delivered. The manufacturer was made aware of the failure. The failure mileage was approximately 40,000. The VIN was unavailable.
