Hyundai Motor America (Hyundai) is recalling certain 2023-2024 Palisade Tucson, 2023 Sonata, Elantra, and Kona vehicles. The electronic controller for the Idle Stop & Go oil pump assembly may contain damaged electrical components that can cause the pump controller to overheat.
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

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 old and has been properly maintained. When I brought the vehicle to an authorized Hyundai dealership, I was required to pay a $248 diagnostic fee simply to identify the failed component. After the diagnosis, I was presented with an estimated repair cost of approximately $1,600 to replace the defective coolant valve and associated parts. I believe these charges are unreasonable because the failure appears to involve a defective component rather than normal wear and tear. Consumers should not be expected to pay significant diagnostic and repair costs for a major cooling system component that fails prematurely. I have also learned that Hyundai has issued recalls and/or service campaigns affecting certain other vehicles for cooling system-related issues. However, my vehicle is apparently not included in those actions, despite experiencing a similar premature failure. While I understand that recalls apply only to specific vehicles and conditions, I respectfully request that investigators determine whether the defect affecting my vehicle is related to those existing actions or whether additional vehicles, including my 2023 Hyundai Kona, should be evaluated for expanded coverage. My research also indicates that other Hyundai Kona owners have reported similar coolant valve fail

My horn is not working again. It was replaced when I initially got the Kona in 2023. It did not work coming out of the dealership. And now again it is back to not working. This is a liability and also a danger to my children.
