WHEELS
I am writing to formally escalate a serious safety concern regarding my 2021 Hyundai Kona Ultimate, which was sold to me as a new vehicle in April 2021 but was equipped with tires manufactured in 2019 at the time of delivery. This issue raises significant concerns regarding product safety, quality control, and customer protection. I have already contacted Hyundai Customer Care and have been working with a case manager regarding this matter. During our conversation on February 23, 2026, I was informed that the issue would be investigated and that I would receive an update by February 27, 2026. As of today, I have not received any meaningful response or resolution. The absence of communication and delay in addressing a matter that directly affects the safety of my family is unacceptable. I currently reside in the Boston, Massachusetts area, where winter driving conditions regularly involve snow, ice, and freezing temperatures. Tires are one of the most critical safety components of a vehicle under these conditions. Installing tires that were already approximately two years old at the time the vehicle was sold as new significantly reduced the usable safe life of those tires. According to guidance provided by the tire manufacturer, tires installed on new vehicles should ideally be recently manufactured, and tire age is a key safety consideration regardless of mileage. Because the tires on my Kona were manufactured in 2019, their safe service life has effectively been shortened by several years through no fault of my own.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
The embedded navigation system tends to provide directions getting the vehicle into off road areas that are not designated to be driven. This not only causes damages to the car but also leads to unsafe situations. While driving in the Upper Peninsula of Michigan headed to the Kitch-Iti-Kipi, it took me to tall grass and high voltage towers almost getting me to a ditch. While driving in St. Augustine Beach, it almost took me to the ocean. While driving near Lubbock Texas around a detour due to construction, it almost took me to a cliff.

STRUCTURE:BODY, SUSPENSION, WHEELS
The plastic covers such as the wheel wells, inner fender linings, under body shield, are very prone to coming off by either minor objects intruding them or hitting them such as branches, rocks, or even water and sand. While driving on a highway at the Upper Peninsula in Michigan on October, a large branch on the road got inside the front wheel well and it took it away. It flew into the highway as debris and cars began evading them. I had to replace it at my expense and it come off again while driving on sand on a beach in St. Augustine Florida on December (the car is 4x4 off-road capable and sold as such). The underbody shield began coming off in a highway in near Austin Texas around a construction zone where loose gravel was present. Almost all plastic clips were missing after I was informed by a driver that plastic parts were coming off my car striking his vehicle. The wheel well of the driver side also began to come off. I had to zip-tie it; no holes were damaged but it was fully scratch and cracked in multiple locations from touching the pavement. I was hit on the side of the rear of the passenger side door and the plastic cover came off. I replaced it but it seems those plastic parts are superimposed and not well secured into the body of the car and can come off fairly easily during driving becoming road hazards that can result in a crash to vehicles driving from behind or even people or animals. I had a Sonata and the same under shield came off while driving to Miami on December 2024, their service department only had it cut leaving the underbody exposed.

STRUCTURE:BODY, ELECTRICAL SYSTEM
A week after I got my 2025 Hyundai Kona Limited, while trying to have the moonroof when headed into the highway since it gets too noisy if left open, the glass will touch the guard and then back away and remain fully open. However, the issue becomes more serious when it starts to rain or snow as it will remain open. In three occasions, the moonroof will not close. During a downpour, I had to use a large umbrella to avoid water to flood the car. Had I not had an umbrella or something to prevent water from getting in, the vehicle electronics could have become damaged including my personal belongings including but not limited to my sensitive medical equipment. Had I been in a snow shower, I will have gotten sick with a cold. I had reported the issue several times to different dealers and they only say it needs to be cleaned and reset. I had a Sonata with the same moonroof for over three years and I never experienced such an issue.

STRUCTURE:BODY, SERVICE BRAKES, ELECTRICAL SYSTEM
I have a 2025 Hyundai Kona Limited. On [XXX], around the afternoon on Sunnyvale, California, while exiting [XXX] headed to Lake Tahoe, the liftgate bolt that attaches to the body had buckled mechanically as the system did not back away when a flashlight that came out of a travel bag was blocking the way to have it closed. The car computer thinks the liftgate is open even though the lock is secured. The car computer allows to drive without seatbelts secured or closures ajar for a few seconds at low speed but then it automatically with little warning engages the electronic handbrake while driving. I was driving on a highway in a middle lane when the car engaged without my consent the electronic handbrake locking the wheels and I almost got rear ended and killed by a semitruck. I had to floor the gas pedal and steer to a shoulder to request a tow. Since it was a long weekend before Presidents Day, I had the car taken to the nearest dealer in Modesto California. Their service department invented a lie that due to a side crash, which was a failure of the collision mitigation system that happened months ago, is the cause and that it is my fault even though the driver admitted responsibility but it is an unrelated issue. There should be a way of overriding the car computer so it does not engage the electronic hand brake on the middle of the highway, specially at night as this creates a road hazard that can lead to death. I replicate the issue with a rental, a Hyundai Tucson, they use the same gas strut and bolt that in my opinion has a very narrow gage. As you can see in the picture, the passenger side bolt is fine, the driver side is buckled. The side accident that happened on May 2025 was on the passenger side but the liftgate is fine; at any rate both sides should be deformed not just one if that were to be the case but it is not. Dealer and Hyundai attempting to sideline the issue to avoid a warranty and recall in my opinion. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ENGINE, UNKNOWN OR OTHER
Was driving when the car seemed to lose power and would not accelerate and started shaking. Check engine light came on and got it read, the code indicated a misfire and other errors. There was no one local to fix it as we were out of town. So we replaced the plugs that were indicated and noticed how badly damaged they were. Vehicle started to drive better before stalling out again and replacing the rest of the plugs. Was able to get it home and seemed to be driving normally but then we noticed it has an oil leak now. We have to keep a religious check on the oil because of the amount leaking and the fact the car isn't giving us a low oil warning. We took it to the dealership and they said we needed a new engine and it was just outside the power train warranty. All of this occurred our 78,000-80,000 mile mark. The dealer would not even change the oil before of how bad the leak was. This car was for our teenage daughter and its not safe for anyone to drive. I believe the dealership knew this car had issues, we bought it pre-owned and have only had it 6 months.

VEHICLE SPEED CONTROL
I bought the car in November 2025. I was on a highway, going at a comfortable, 65 mph speed (a few weeks after purchasing this happened the first time ). Suddenly, the car stopped accelerating, of course I panicked, slowly pulled off to the shoulder, and shut the car off. Luckily, it was not rush hour . I restarted the car, and it was normal driving. I texted my salesperson and asked if he had heard about this issue. He said no. No warning lights or messages appeared as that happened. The speed had decreased and stayed at 36 mph for a few seconds. A few weeks later, it happened again, this time it stayed at around 36 mph. I pulled over and shut the car off, restarted, and no issues. This time I told my salesperson I wanted to bring it in, but they had a one-month wait and offered no help, didn't seem phased or concerned. I took the appointment for February 17, which was approximately a 4-week wait. Again, no lights or warning signals. The third time this happened I was merging on to a very busy ramp to enter a busy highway, and the speed stopped at 11 mph, and I panicked, pulled over restarted the car and that was enough for me to call and insist they take the car as soon as possible, as we were expecting a major snowstorm which did happen the next day. I did not take the car out and brought it in to the dealer on Monday. Again, they seemed unconcerned but took the car after I insisted. The car has been there for 2-weeks now and they claim they cannot find a problem. I called Hyundai corporate. After investigating, they too said there was nothing they could do since they could not find a problem. I may add that while this is happening I am stepping on the gas and nothing happens.

VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
While the cruise is set, traveling on I44 with no other car in front of my Kona, the adaptive cruise control will start to flash and apply brakes immediately. The speed will drop instantly. Thankfully no other vehicle has been behind me, otherwise it would have caused a massive wreck. I have taken the Kona to the shop 5 to 6 times for this situation, but they will not do anything since they can not duplicate it. I took a video recording of it happening, and they still would not do anything. The first incident was December 31, 2024. This happens every other week when I travel out of town for my daughter parenting time with her dad.

POWER TRAIN, ENGINE
The cars engine vibrates when accelerating and hesitates. It is always dangerous to stall after hitting the gas. This issue causes many near accidents. It began to vibrate at less than 70k. It has 90k now. These engines have had issues and mine is no exception. They should recall this engine as it's dangerous. top of the line and poop.

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)

FUEL/PROPULSION SYSTEM, ENGINE, ELECTRICAL SYSTEM
Over the last 2 1/2 months the car has shut off approximately 5 times while driving, without warning. Most instances have been while pulling into a parking lot, but one time (so far) it shut off while trying to back into my driveway. I'm fearful it will happen while on the freeway. I took it to the dealer, but there wasn't a fault code so they refused to look at it unless I left the car with them to drive, and wanted to charge me $45/day for a rental so I could get back & forth to work until it happened again while they were driving it.

FUEL SYSTEM, GASOLINE
The contact owns a 2026 Hyundai Kona. The contact stated that while the vehicle was parked and turned off, an inspector discovered a puddle of fuel on the ground underneath the vehicle. The vehicle was taken to the dealer, who determined that the hood insulation was damaged, and the fuel lines were punctured. The vehicle was not repaired. The contact stated that two other GSA fleet vehicles of the same year, make, and model, as well as a coworker who owns a 2025 Hyundai Konda had experienced the same failure. The contact related the failure to rodents chewing the organic-based fuel lines. The manufacturer was not made aware of the failure. The failure mileage was approximately 900.

ENGINE
The vehicle displayed a warning lamp indicating a Cooling System Performance failure. The specific defect relates to the Integrated Thermal-Management Module (ITM) and the thermostat opening prematurely, corresponding to Diagnostic Trouble Code (DTC) P218100. This issue requires a repair outlined in Technical Service Bulletin 25-EM-007H, involving a spring installation and ECU update. This failure creates a serious safety concern because improper thermal management can cause the engine to overheat or force the vehicle into a reduced-power 'limp mode' without warning. A sudden loss of acceleration or engine stall while driving in traffic significantly increases the risk of a crash.

LANE DEPARTURE: BLIND SPOT DETECTION
The Blind Spot Collision Warning (BSCW) light comes on 10 minutes into a drive (we live in a rural area and drive two lane roads for at least 25 miles before multiple lanes). I have had the car in for service on the system twice before learning that this is built into the system. Others are having the same problem, (see the two Hyundai Kona forum links below). I've spent about $600 trying to solve a problem Kona already knows existed (see p. 5-52 of the 2021 Kona owner's manual). Of course I hadn't read the entire manual, but I feel the service technicians should have. I will attempt to put a more detailed description in the files below.
