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

We were diving on the interstate and the RPMs went up all the way up and after it came back down the car wouldn’t respond anymore and came to a stop while on the interstate putting my family safety at risk! There were no notifications before the car came to a stop while on the interstate but when we pulled over to the shoulder we tried to start the car again and then the Check engine light came on saying there was issues with the transmission control system. We had the car towed to Hyundai of Metairie on 5/28/23 and notified Hyundai of everything that happened. We were assigned a case# from Hyundai on 5/30/23. We were later contacted by the Hyundai case manager on 6/9/23 and the Service department letting us know that a new transmission will need to be installed on a brand new car we only had for 33 days at the time of this incident!

My 2023 Hyundai Kona SEL FWD currently has approximately 1500 miles on the odometer. Pretty much since the day I my 2023 Kona SEL on 9/3/2022, the car has had an issue where, after I start the car and begin driving it for about 20 or 30 seconds the car will lose power entirely. Engine shuts down, and the following warning codes illuminate-Immobilizer, check engine light, battery light, and oil lights come on and the car prompts me to restart it. Sometimes an alarm will also sound, flashing red, with the following message on the vehicle's information display "Engine Off! Shift to N, then start engine." At other times the following message will appear "Shift to P and N to start engine." Initially this happened once or twice a week, 1-2 times a day, usually after the vehicle has been powered off for 12 or more hours. As of the writing of this message, 11/2/2022, this issue occured 4 times in one day. The first time in the morning while I was driving the vehicle at low speeds and applied the brakes, and the other 3 times in the evening, also while I was driving at low speeds and applied the brake. Fortunately, vehicle shuts down when I am driving at low speeds while the brake is applied. I personally feel unsafe driving the car, because I am not sure if the issue will worsen and the vehicle will lose power while it being driven at higer speeds and public roasds. I have a servicing appointment scheduled my with Hyundai dealership for 11/11/2022 (this message is dated 11/2/2022). Honestly, I am very concerned the problem will worsen. I hope the dealership will be able to reproduce and rectify the issue. I have opened a case with Hyundai USA in this regard as well. I am not sure what specific system is causing the above warning lights and warnings to appear, or causing the vehicle to lose power while being driven at low speeds with the brake applied, but the vehicle would defintely be available for further inspection if needed.
