2023 Hyundai Kona owner complaints (15)

• ELECTRICAL SYSTEM,FORWARD COLLISION AVOIDANCE

  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 (FOIA), 5 U.S.C. 552(B)(6)

• ENGINE

  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

• ELECTRICAL SYSTEM,UNKNOWN OR OTHER

  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)

• VEHICLE SPEED CONTROL,SERVICE BRAKES,FORWARD COLLISION AVOIDANCE

  After a routine service visit, the vehicle’s braking and speed‑control systems began to behave abnormally. The ABS/ESC control module was replaced or reprogrammed without documentation, and immediately afterward the vehicle’s braking feel, speed‑control behavior, and forward‑collision warning timing changed noticeably. These changes created a safety risk because the vehicle no longer responded in a predictable way compared to its original performance. The affected components are available for inspection upon request. The issue was reproduced multiple times under normal driving conditions. Braking response became inconsistent, and the speed‑control system no longer behaved as it did before the service. The timing and behavior of forward‑collision alerts also changed compared to pre‑service operation. These changes created unpredictability in traffic, especially during following‑distance adjustments, stop‑and‑go situations, and sudden‑braking scenarios. The dealership did not provide technical documentation or explanation for the module replacement or configuration changes and did not acknowledge the change in system behavior. The manufacturer’s customer service reviewed the case but did not provide technical findings. An independent service center could not verify the original configuration because the manufacturer did not provide the Manufacturer Build Sheet. The vehicle has not been inspected by police or insurance representatives. No warning lamps or dashboard messages appeared before or after the issue. The only indication of a problem was the sudden change in braking, speed‑control, and forward‑collision system behavior immediately after the service visit.

• POWER TRAIN,ENGINE,FUEL/PROPULSION SYSTEM

  My Kona N Line is not functioning well. Especially after driving for a longer period of time. About 60% of the time, upon letting go of my brake, the car jerks. Going from 0 - 5 mph is the worst. The car definitely hesitates many times. Again, it is when I have driven it for over 10 minutes. I took the car to a service department in El Monte, CA on 11/1. They cannot find the problem. They rode with me and it did not show at that time. They released the car to me. The Kona N has a recall but not my car, the Kona N Line. The recall is for the same problem. I am extremely frustrated. I have another appointment on Tuesday of this week to take to the Glendora service department. I don't know what to do. I am not one to complain but this is not safe. This is my fifth Hyundai. Nothing but good cars until now. Please advise. [XXX] [XXX] . INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

  I was trapped inside the liftgate of my 2023 Hyundai Kona and was unable to operate the emergency release. I had the key fob with me and the car was unlocked, but the trunk would not open from the inside. I tried sliding a standard key and a flat card into the release, but it would not engage. It was not specified that the mechanical key inside the Hyundai fob was required. The release is a small black sliding latch at the bottom of the liftgate with only a car symbol. It is recessed, not easily visible in low light, and does not glow in the dark. I also could not climb over the rear seats because the liftgate hood was sealed, so the fire department had to open the trunk to get me out. Even the operator and the fire department found the instructions difficult to determine. While this may be a rare circumstance, it could have been dangerous. I was able to get out safely, but it would be helpful if the emergency release were redesigned with clearer instructions or made more visible, such as using neon or glow in the dark markings, so that in the future it can be accessed more easily by anyone inside.

  The issue is the horn. On three different occasions, I've attempted to use the horn and it wasn't working. I've taken it to Hallmark Hyundai in Flowood and they've repaired and/or replaced the horn on four separate occasions. The new horn is always working when I leave the dealership, but it eventually goes out. Or it goes out for a period of time and then comes back without explanation. My most recent horn outage happened while I was driving on I-55 in Jackson MS and an 18 wheeler started shifting in my lane. I wasn't able to notify them with my horn and ended up having to drive on the shoulder to avoid a collision. This is a major safety issue and they haven't taken the time to remedy it.
