The horn on my 2023 Hyundai Kona has failed for the THIRD time. This is a dangerous situation. The time before this I barely avoided an accident when a pickup truck was accelerating very fast in reverse from a driveway and didn't see me. Luckily no one was in the oncoming traffic lane and I was able to accelerate into that lane and avoid an accident. But I could not warn him, my horn wasn't working. I can't warn anyone that they're about to drive into my space/lane. IT ISN'T SAFE. Hyundai needs to permanently fix the horns. I have to test mine everyday when I start my vehicle. I shouldn't have to do that!! Do you do that?? Do most people have to do that?? DO SOMETHING TO HELP ME!!!

I was in a rotary and there were two lanes and they both exited to a bridge. I was on the outside lane of the rotary and when exiting the rotary the car from the inside cut me off and I was unable to alert the driver because me HORN wasn't working.

I was driving to work on a normal day under normal circumstances when a check engine light won my dashboard. Seconds later my car started showing car is over heating. I immediately swayed from the speed lane to the side of the road almost getting into a crash as other vehicles were at full speeds behind me. I immediately called dealership and made an appointment. My vehicle experienced a premature failure of the cooling coolant valve, a critical component of the engine cooling system. This failure resulted in diagnostic trouble codes, warning messages, and concerns regarding the reliability of the vehicle. A component of this importance should not fail on a vehicle that is only three years o
