The horn on my vehicle completely stop working.  There were no alert messages and I found out that it wasn't working when I needed to use it.  I was driving 55 miles per hr in a highway and another vehicle was about to switch lane to merge into my lane and driver did not see me and almost got into an accident.  When I try to use the horn to alert tge other vehicle, horn did not work.  It still doesn't work.  Took my vehicle to Millenium Hyunday Dealership in Hempstead, NY and was told by service advisor that horn is only covered up to 60,000 Mike's because is an electronic feature.  I disagree with that assessment and believe this is a safety feature that needs to be reevaluated.

HYUNDAI SONATA 2024 UNKNOWN OR OTHER

While driving on the highway on 4/4/26 at 10:40 pm the dashboard and the headlights went out. The outage lasted about 5 seconds and then they came back on. I drove another 40 minutes and did not have another problem. My safety was put at risk because I could not see the road and others could not see me! There were no warnings prior to the problem. This is the second time in a year that this incident has happened. The first time was in September 2025.

HYUNDAI SONATA 2024 EXTERIOR LIGHTING

Sudden loss of acceleration. This occurred while making a left turn across traffic from a stop. At approximately 7mph the car would not accelerate any further. I was luckily able to coast the vehicle into a center turn lane. Upon coming to a stop I was unable to get any acceleration. The vehicle was turned off and turned back on again and operated normally. There were no trouble codes displayed.

HYUNDAI SONATA 2024 POWER TRAIN

While driving the vehicle the other night, the cars electrical system completely shut off for a few seconds before popping back on. The whole car inside and out went completely black. It was around 10pm on a dark country road. I had the seat heater on high and the defrost on high because it was cold. It appeared to happen when the auto high beams were supposed to engage. Instead of them engaging, the whole cars electrical system just shut off. No headlights, no instruments, interior lighting, console display, nothing worked. The car was in battery mode at the time, and it sounded like the whole car just shutoff. I took my foot off the accelerator wondering what happened, and before I could understand what was going on, everything came back on. It did not prompt me to start the vehicle again. The auto on/off brights never worked like they were supposed to again either. I had to manually engage and disengage them. Thankfully it was just me on that stretch of road going 30mph at the time or it could have ended badly.
