2023 Hyundai Kona Electrical System Problems

Dear Hyundai Motor America Consumer Affairs, I am formally escalating a safety defect involving my 2023 Hyundai Kona, VIN [XXX] , purchased [XXX]. Since the purchase, the vehicle’s horn has repeatedly failed. I have brought the car in for service multiple times, and the issue is thoroughly documented in service records and email correspondence. Despite these efforts, the defect has not been permanently resolved. A non-functioning horn is a serious safety issue. This defect is not isolated; identical horn failures in Hyundai Kona vehicles are widely documented across public Internet forums, consumer complaint sites, and owner reports, further underscoring the seriousness of this issue. Given the repeated repair attempts and ongoing safety risk, I am requesting immediate corporate-level review and a clear, permanent resolution. This matter requires prompt attention. [XXX] , service manager, informed me today that my horn was changed/serviced 4 times already. As of today, 2-10-2-26 he is ordering me another horn. Please respond in writing with next steps. Sincerely, [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2023 Hyundai Kona. The contact stated that the horn was working intermittently. The horn occasionally operated but had become permanently inoperable. The dealer was notified of the failure. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 106,000.

The horn is not working in my vehicle. I found this out today when I almost had someone collide with my vehicle while I was on the highway, not once, but twice. I was unable to use my horn to alert the other driver. I called Hyundai and they said it is not covered under warranty and this is a known issue with my vehicle. I have only had the vehicle for 3-4 months and this should not be happening. I cannot safely drive without a horn and if something happens to me or my vehicle and Hyundai knows its an ongoing issue with this year, make, and model, I am not sure what I can do. Please make this right.

Horn keeps failing

Rear latch unlocks while vehicle is running or not running up to 30 times at once. Rear latch unlocks without key being in vehicle. This has been reported to Hyundai Motor America since August 2025. The front collision warning goes off at random times, left side departure goes off at random times.

The horn stopped working. The first time, replacing a fuse fixed it, the second time I had to go to the dealership to get the horn replaced under warranty. There were no warning lamps.

The contact owns a 2023 Hyundai Kona. The contact stated that while pressing the horn pad, the horn failed to produce a sound. The vehicle was taken to the dealer, and the horn was replaced; however, the failure persisted. The contact stated that the horn had been replaced four times and was scheduled for a fifth horn replacement. The manufacturer was informed of the failure and opened a case. The failure mileage was approximately 12,000.

Horn does not work.

While driving, my car completely turned off and the dashboard say “engine turn off”. This happened on two separate occasions. Also on separate occasions while i was driving the beep to indicate that i was too close to another car went off when i was not near another car, during that time it also emergency breaked on its own.

The contact owns a 2023 Hyundai Kona. The contact stated that when starting the vehicle, the system check lights were illuminated normally; however, all the system symbols had a red "exclamation mark" next to the symbols. Additionally, the contact stated that the horn and many safety features were no longer operable. The contact stated that the Lane Departure warning, Blind Spot warning, and the radio were inoperable. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the main computer was not interfacing with the safety systems. The contact was advised by the dealer that there was no remedy for the failure. The vehicle was not repaired. The manufacturer was informed of the failure. The failure mileage was approximately 3,000.

MY HORN STOPPED WORKING LAST JULY AT 7467 MILES, AND STOPPED WORKING AGAIN INJUNE AT 10,000 MILES

The contact owns a 2023 Hyundai Kona. The contact stated that while pressing the horn to avoid an accident, it was discovered that the horn was inoperable. The contact stated that the failure was intermittent. The cause of the failure was not yet determined. The local dealer was informed of the failure. The manufacturer was not contacted. The failure mileage was 12,000. The VIN was not available.

Horn stopped Working out of nowhere.

Rodent damage found during 1-year maintenance. This is an increasing problem that is under-reported. Damage was found before any wires were effected, however, the wiring was exposed and would have caused a malfunction had this not been detected by technician. 1. Automakers across the board are using cheaper, soy-based elements to wrap wiring and customers are having to deal with the result of subpar parts. 2. With automakers increasing the time allowed between oil changes, customers are given a false sense of functionality in the vehicles they drive. 3. Automakers that advertise "free maintenance" should not be allowed to limit maintenance to once per year or every 5,000-8,000 miles, as more prudent inspection would prevent customers from unknowingly having their cars devoured by rodents.

The vehicles horn randomly decides not to work. The horn has been replaced once, but the same wiring was kept the same. The vehicle is going back after a few months due to horn malfunction again.

The rear door Latch opens while vehicle is moving and I've have taken it to service and they don't know what failure is al about.Its a manufacture failure.

Horn no longer works when pressed at 11,396 miles. Manufacturer will not offer loaner vehicle. Vehicle is not safe to drive without horn. Manufacturer does not seem to care that it's broken and will not expedite the repair process. I will have to drive this vehicle for approximately a month with no horn. My safety is put at risk as I cannot warn other drivers of impending danger and cannot warn other drivers they are about to hit me. The manufacturer has not yet inspected the vehicle. The inspection will take place on August 21st. There were no warning indications before I attempted to use the horn and it didn't work. It's possible that the horn has been broken for a while.

Radio stopped working. Screen went blank. Looks like a loading screen and then nothing. Radio does not come on at all

I have been having electrical issues since I bought this car. The radio screen goes black for no reason, the clock changes time on it's own the Android auto only works intermittently. The tire lights come on and say there is 0 psi in the tires. Right now it says that 1 tire is low but the psi is the same in all 4 tires. I think this car was damaged during Hurricane Ian and the dealership still sold it to me. I have already brought it to the dealership to be fixed and it still has issues.

The radio/GPS screen cuts out and goes completely blank and I can't turn it off or down or do anything with the radio. The tire pressure lights come on and off at random times. The backup camera randomly stays on when I'm driving and I can't get it to go back to a regular screen. The lights randomly turn on and off when I am driving. There is obviously some kind of electrical issues.
