Consider taking a coffee break distracts driver. This issue warrants immediate consideration for a recall. Anytime I drive, this warning keeps going off shortly after going on a windy or pothole filled road (all of PA). Despite driving safely and normally, the problem persists. This occurs regardless of the time of day, weather conditions, or whether I am sitting upright or reclining. The warning randomly activates and deactivates, sometimes without any intervention. Occasionally, I simply allow the warning to sound without taking any action, and it remains active for a few seconds or until it triggers a warning that the system will be turned off, at which point it deactivates. I have attempted various troubleshooting methods, such as keeping my eyes open, adjusting my seating position, wearing and removing my glasses, and tilting them to minimize glare. None of these methods have proven effective in preventing the warning from activating or in making it deactivate. This is a persistent problem. Hyundai dealerships initially informed me that the warning might be an annoyance and their response was to simply refrain from using it. However, if a basic feature like cruise control in a 2024 & 2025 model is rendered unusable due to a design flaw (which this certainly is), it constitutes a clear violation of safety standards and should be addressed through a recall. The incessant alerts are highly disruptive and can be quite frustrating. For instance, driving with an arm in the 12 o’clock position triggers a warning, while wearing polarized sunglasses also results in an alert. The presence of a setting to disable the warning is a welcome feature, but the system’s persistent alerts can be overwhelming. The alerts continue even after taking a break. It is distracting and a safety hazard. Drivers should be able to adjust the sensitivity of the feature or turn it off all together.

ENGINE
My 2020 Hyundai Kona experienced an engine-related malfunction. An authorized Hyundai dealer inspected the vehicle, confirmed diagnostic code P1327, and determined that the complete engine required replacement. Hyundai authorized the replacement, and the vehicle remained out of service for approximately two weeks. The engine defect created a safety concern because an engine malfunction could cause reduced or complete loss of motive power while driving, increasing the risk of a crash. The dealer inspected and removed the original engine; I do not know whether it remains available for further inspection, but the repair order and diagnostic records are available. I am filing this complaint so NHTSA can document this engine failure and determine whether it is related to NHTSA Campaign 21V301 / Hyundai Recall 203 and whether additional investigation or corrective action is warranted.

ENGINE
At approximately 100,500 miles, the 2.0L Nu engine experienced a sudden, catastrophic internal failure while operating, causing a loss of power and stalling. Failed Component & Availability: The engine block assembly failed internally due to severe low compression (95 psi) across multiple cylinders and intake valve leakage. The original failed engine component was replaced and retained by the servicing dealership's service department during the long-block replacement. Safety Risk: The sudden loss of engine power and stalling occurred while navigating active traffic, creating an immediate crash hazard due to the loss of momentum and propulsion on a public roadway. Diagnosis & Confirmation: The failure was independently confirmed by a certified master mechanic (compression test showing 95 psi) and subsequently diagnosed and confirmed by an authorized manufacturer dealership service department. Inspection History: The vehicle was fully inspected by the authorized dealership, which verified the low compression, confirmed internal engine failure, and performed a full long-block engine replacement.

I purchased this vehicle new on July 28, 2026. NHTSA Recall 26V-452 / Hyundai Recall 306 was dated July 13, 2026, and the VIN showed the recall as incomplete when I discovered it. The dealer states that it was unaware of the recall at the time of sale. I am reporting this to document that a new vehicle was delivered to me while this safety recall was unrepaired. I intend to have the recall repair completed.

The contact's daughter owns a 2019 Hyundai Kona. The contact stated that while her daughter was driving 40 MPH, smoke started coming from under the hood. The vehicle lost power and came to a stop in front of a convenience store, blocking the entrance. Several unknown warning lights were illuminated. The driver called the Fire Department, and it was confirmed that the engine compartment displayed severe heating damage. There was no fire. The firemen on the scene recommended that the vehicle be towed. The vehicle was towed to an independent mechanic, and the contact was informed that the failure was a known failure and might be covered under an extended warranty program. The vehicle was towed to the dealer, where it was diagnosed and determined that the engine had seized. No electrical failure was found. The dealer initially offered to cover 95% of the cost of the repair. The manufacturer was notified of the failure and offered to cover 85% of the cost of the repair, but the contact declined. The contact stated that the Knock Sensor Detection System (KSDS) software update had previously been completed on the vehicle; however, the update failed to prevent the engine failure. The manufacturer informed the contact that the extended warranty could not be applied due to a transfer of ownership to the contact's daughter. The failure mileage was approximately 81,000.

ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: WARNINGS
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 received the recall, brought the Kona in had the software download. Now the engine code indicates engine issues with the safety code. Hyundai customer service representatives stars because the issue wasn't found and the software download completed this doesn't fall under the recall. I do have an appointment to bring the Kona into the dealership but because Hyundai states it is no longer under the recall I am responsible for the towing and will not be remembursed. When I initially brought the vehicle in I was told if the pistons and engine codes appears under the recall layer on towing and replacement of the engine is covered. I was also told my engine covered up to 150,000 miles. Even through I only have 65,000 Hyndai dealer and customer service stated it is not as this is only if the engine showed signs at the time of the software download. This is absolutely wrong to be treated like this and been advised by my local mechanic this does appear to be part of the recall, will deregulate, or engine could seize up causing a safety issue.

ENGINE, POWER TRAIN, SUSPENSION
I am filing a safety complaint against Scott Stark’s South Point Hyundai for selling me a vehicle with an active open safety recall, a blown transmission, an A/C failure, and a dry-rotted tire. Before returning the car for service under a promised 1,000-mile warranty, my sister, who has worked for Corporate Hyundai for 15 years, helped me conduct a full intake baseline inspection at her dealership. We performed a recorded 360-degree video inspection, took high-resolution photos of every square inch, and ran full computer diagnostics, which confirmed zero tool marks on any bolts under the hood or on the transmission, and all diagnostic readings were perfectly recorded. South Point Hyundai kept my vehicle for 10 days for repairs, making excuses about test drives and failing to find technicians. However, a hidden GPS tracker tucked deep under my passenger side carpet meticulously documented every single time the vehicle moved or remained completely stationary on their lot. Upon picking up the vehicle, my sister scanned the car immediately with her diagnostic computer. The readings are now completely erratic and all over the place compared to the baseline corporate readings we documented 10 days prior. Physical inspection reveals that bolts have been turned, internal components have been actively tampered with, and parts have been structurally altered. The evidence directly indicates that this dealership used my personal vehicle as an unauthorized parts donor vehicle to harvest components, severely compromising its mechanical integrity, structural reliability, and overall road safety. This severe tampering has left the vehicle completely unsafe to operate. We possess full video evidence, high-resolution photographs, GPS tracking logs, and comparative corporate Hyundai diagnostic data verifying this severe mechanical fraud. I have turned this info over to Corporate Hyundai, the DMV, and federal enforcement agencies due to safety risks.

ELECTRICAL SYSTEM, ENGINE
COMPONENT/SYSTEM: Air Conditioning (HVAC) / Climate Control System and closed-loop refrigerant lines. The vehicle and all climate control components are available for immediate inspection. SAFETY RISK: Total loss of cooling in peak summer heat (90°F-95°F+) causes cabin temperatures to rapidly exceed 110°F. This sudden heat trapped in the vehicle caused me (the driver) acute heat exhaustion, culminating in a medical fainting episode. The vehicle regularly transports my newborn baby and toddler, subjecting them to severe heatstroke risks. Additionally, an ongoing 4-year chemical refrigerant leak inside an enclosed EV cabin creates an active toxic inhalation hazard for all passengers. DEALER CONFIRMATION: Yes. The failure has been repeatedly confirmed and documented by authorized Hyundai dealerships, including Paramus Hyundai, Garvey Hyundai, and Liberty Hyundai. Technicians repeatedly measured zero refrigerant charge/pressure, performed UV dye tests, and completed major repairs including AC line and radiator rebuilds without resolving the leak. INSPECTION HISTORY: Yes. Inspected multiple times by authorized Hyundai dealership technicians under official Corporate Case Nos #42549212, #41020884, and #23781133. WARNING LAMPS/SYMPTOMS: No dashboard warning lamps or error messages ever appeared. The only symptom was the AC suddenly blowing boiling hot air as refrigerant leaked out. This failure first appeared in Summer 2022 (shortly after vehicle purchase) and has recurred every summer for 4 consecutive years despite repeated warranty repair attempts.

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
