2022 Hyundai Kona Electric problems

We took this car in to the dealer to implement the "BMS Battery Logic Improve (26-01-065H)" update on 9/17/26. We have had two issues that appear to be software related and might be caused by improper voltage from the 12 volt battery. The issues are: - Warning messages appeared "Check forward safety system" and "Smart cruise control conditions not met”. The Smart cruise control stopped working. This is still happening. Started on October 10. - The Charging Port door release required 3 or more clicks of the "unlock" function to open. We resolved this by changing the unlock setting in the settings software, making us think this is a software issue from the update. Started on September 18. Safety is decreased by not having Smart Cruise and Forward Safety Systems available. We will go to the dealer today. We have reported this to Hyundai, case #43378707. No one else has inspected the car. The warning lights appeared on October 10th.

While driving my 2022 Hyundai Kona Electric at a low speed, pulling into a parking space, the electronic braking system suffered an immediate, catastrophic failure. Upon pressing the brake pedal, the vehicle completely failed to provide power brake assistance or slow down, resulting in a low-speed collision. The airbags did not deploy. Immediately following the crash, a diagnostic scan of the vehicle’s chassis network revealed active diagnostic trouble code C160404 (ECU Hardware Error / Internal Self-Test Failure), confirming a hard electronic fault within the Integrated Electronic Brake (IEB) module. This vehicle platform has a documented history of dangerous IEB signal and software anomalies under past federal actions like the federal safety agency Campaign 20V748000, where regulators explicitly stated that these failures significantly reduce braking performance, extend stopping distances, and cause crashes. My vehicle suffered this exact failure mechanism, posing an immediate threat to life and property. I am requesting a formal federal investigation into this specific electronic brake computer failure to prevent further consumer injuries or collisions.

I found a lot of debris of metals contaminated in the gear reduction oil when I changed my gear reduction oil. I had a Vortex oil lug nut, which it sucks all of the metal debris in. I have pictures of that as a proof. I think this is a design flaw that Hyundai should recall, but they didn’t. Now it caused a clicking noise whenever I accelerate or step on the accelerator pedal. Additionally, their are some glitches with their software where it disconnected the wireless Apple car play and the back up camera didn’t show up sometimes whenever I put into reverse.

1. Component or System Failed or Malfunctioned: The primary component that has consistently failed or malfunctioned is the air conditioning (AC) system. The AC unit does not adequately cool the vehicle's cabin, especially in hot weather. The vehicle is available for inspection upon request; it has been previously inspected by authorized Hyundai dealerships. 2. How Safety was Put at Risk: The malfunctioning AC unit poses a significant health and safety risk, particularly due to the presence of a [XXX] infant who frequently rides in the vehicle. Driving in a hot car without effective cooling can lead to heat-related distress for a young child. There is also a concern that this persistent issue may indicate a broader manufacturing defect, potentially warranting a safety recall. 3. Problem Reproduced or Confirmed by Dealer/Service Center: Yes, the problem has been repeatedly reproduced and confirmed by an authorized Hyundai dealership. Paramus Hyundai has examined this specific AC issue on four separate occasions during the last summer, and a fifth visit is now scheduled/imminent. Despite these multiple service attempts, the issue remains unresolved. 4. Inspection by Manufacturer, Police, Insurance, or Others: The vehicle and its AC component have been inspected multiple times by an authorized Hyundai dealer (Paramus Hyundai). The manufacturer, Hyundai Motor America, is aware of this ongoing issue, as evidenced by two formal customer service cases: an older case (Case Number: [XXX]) handled by Customer Service Specialist Raghad, and a more recent, open case (Case Number: [XXX]) handled by Customer Service Specialist Simran. The repeated advice given for the new case is the same as previous attempts, indicating a lack of definitive resolution despite manufacturer involvement through their customer service channels. 5. Warning Lamps, Messages, or Other Symptoms: No specific warning lamps or messages have appeared on the vehicle's dashboard related to the INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION

Message: "check/refill coolant light has intermittently come on for past two days. I checked coolant and it is lower than "max" but higher than "min". Also, why is this website saying 0 unaddressed recalls on my car? There are recalls that were not done on my car. Message: "0 Unrepaired Recalls associated with this VIN"

Horn stops working.â it stopped working about a year into owning the car, then again a few weeks later. The horn seems to stop working after windshield wiper fluid is refilled; not sure if it's related though.â I have been in situations where I needed to use the horn but was unable to because it was constantly not working.â

During the winter the vehicle does not produce heat. There is a knocking sound from under the dash and only cold air comes out of all the vents. When it was 20 degrees out I measure 35 degree air out the vents over the couse of an hour drive. The car has been to the dealer multiple times for this issues. They have acknowledged the problem and have tried replaing different parts but the problem still occurs. It's very cold in the car when it's below freezing outside and it's difficult to clear the windows of fog, frost, and snow with no heat. The HVAC system will make the knocking sound when turing on the car and sometimes when driving also. Trying to adjust the temperature will sometimes trigger the noise. I feel the knocking sound and lack of hear are related.

There were several recall/service notices on my vehicle. I brought car to dealer in May and they were unable to address them all b/c I was informed a dealer specific piece of equipment necessary for the recall had broken and they could not address that issue. Why is it saying on the federal safety agency website zero unaddressed recalls for my car? Here are some of the notices: Service Campaign 9A4: Kona EV DTC Inspection, BMS Update, and BSA Replacement – Dealer Best Practice August 29, 2023 I believe there was an additional issue of concern. I originally scheduled for early 2024 & then there was an additional recall/concern and I could not be accommodated until May 2024; however, as mentioned, they were unable to address all the issues at that time. Please let me know.

The push door to the charging port locks and I am unble to open it. It will sometimes unlock if I push the unlock button several times. This is worrisome since I need access to the charging port to charge my batter. Not sure if there is a design flaw with the latch to the door.

While driving slowly less than 5 MPH into parking stall the vehicle accelerated excessively while trying to brake the vehicle it continued to accelerate and jumped the curb while I was still pumping the brakes to try to get it to stop and the car finally stopped after hitting the front of the establishment building. No collision warning went off at this time as well. I checked the mats to see if they were against the accelerator pedal and they were not.
