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 blew out 2 tires hitting a curb and needed to be towed.State police arrived on the other side of the bridge. My HORN has been replaced by the dealer 3 times now.

Dear Hyundai Motor America Consumer Affairs, My name is [XXX], and I am submitting this correspondence as a formal safety and customer-service complaint concerning my 2023 Hyundai Kona SEL, the recurring failure of its horn, and the treatment I received at Capitol Hyundai in San Jose, California. I am requesting that Hyundai Motor America immediately open a corporate case, investigate the dealership’s handling of this matter, preserve all relevant records, and provide me with a written resolution. This complaint involves an unresolved vehicle safety concern. My vehicle’s horn has failed repeatedly. I previously presented the vehicle to Hyundai for this same horn issue in 2024. One of those visits was properly documented. I subsequently returned regarding the horn again, and the horn was made operational; however, to the best of my knowledge, that subsequent visit and/or work was not properly documented in my service history. The horn has now failed again. A functioning horn is an important vehicle safety device. Without it, I cannot reliably warn another driver, cyclist, pedestrian, or other road user when immediate warning may be necessary to avoid a collision. On August 11, 2026, I brought my vehicle to Capitol Hyundai, 1050 Capitol Expressway Auto Mall, San Jose, CA 95136, seeking assistance with this recurring problem. What occurred is particularly concerning because Capitol Hyundai’s own Repair Order documents the situation. The Repair Order states: “CUSTOMER STATES HORN IS NOT WORKING PLEASE CHECK AND ADVISE” and also states: “DEALERSHIP IS REFUSING TO SERVICE CLIENT DUE TO CUSTOMER ISSUE.” I am attaching a copy of this Repair Order. Therefore, there should be no dispute that Capitol Hyundai had actual written notice on [XXX] that I reported an inoperative horn and that the dealership documented its refusal to service me. Instead of resolving the safety concern, I left without the horn being repaired. I was also told that the dealership would INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT

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 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.

Dear Customer Care, I am the owner of a 2023 Hyundai Kona AWD purchased brand new from Vision Hyundai West Henrietta, NY. I paid for the vehicle in full with a cashier's check totaling over $31,000. At just 64,000 miles, the vehicle has become undrivable-experiencing loud noises, jerking, and no acceleration. I was driving and car would not move. These symptoms are clearly drivetrain-related and should be covered under Hyundai's 10-year/100,000-mile powertrain warranty . When I contacted the dealership, I was incorrectly told my roadside coverage had expired at 36,000 miles, Hyundai Warranty Escalation Letters which contradicts Hyundai's stated policy of 5 years/unlimited mileage. Additionally, I requested a loaner vehicle due to the urgency and distance (I'm 80 miles away), but no one followed up, leaving me stranded and without any transportation options. I am requesting Hyundai's assistance:

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.
