While driving approximately 70 mph on I-10 in Louisiana late at night, my 2020 Hyundai Kona EV displayed a “Check EV System” warning while I was on the highway. There were no safe areas or emergency shoulders available to pull over, so I continued driving toward the nearest exit. Approximately 15 minutes after the warning appeared, as I attempted to exit the highway, the vehicle suddenly lost power and rapidly slowed. The vehicle came to a complete stop and could not accelerate, move forward, or reverse. This created a serious safety risk because the vehicle lost propulsion while traveling at highway speed. The vehicle had approximately 62,000 miles at the time of the incident. The vehicle was towed to Giles Hyundai where the dealership diagnosed an internal temperature sensor and resolver failure. Because these components are integrated into the drive system, the dealership replaced the entire traction motor assembly. The repair cost was approximately $9,000. The sudden loss of propulsion at highway speed created a dangerous situation for both the driver and surrounding traffic.
NHTSA complaint 11722050My wife was pulling into a parking place at Home Depot when the car suddenly accelerated, jumped the curb & hit a tree on the sidewalk. It did significant damage to the front bumper of the car but the airbags did not deploy & my wife was not hurt. I am guessing that it will be several thousand dollars to repair.
NHTSA complaint 11667507On 3.22.2025 the rear view camera did not display; either a black screen with text "Check surroundings for your safety," a green screen reading "No camera signa received. Please try again later," or distorted images appeared. Camera was replaced under warranty on 4.14.2025; I learned from Crossroads Hyundai that other vehicles had a recall in effect. Images and work order are included.
NHTSA complaint 116545236/17/2024 12 volt battery was dead; EV was fully charged 6/16/2024 using Level 2 charger in my home garage. AAA charged the battery; I drove to Crossroads Hyundai Loveland, CO and asked to have the converter to the main battery checked; this was not done. Crossroads checked the battery via CADEX with "good battery charge" as result. No other diagnostic work was performed. 8/26/2024 12 volt battery again depleted; AAA charged twice 11:06 am (recharge and retest ) and 3:51pm (Bad & replace). I drove again to Crossroads Hyundai which claimed battery test showed good battery. Technician found a draw dropped after pulling fuses F6 multi media and F16 memory. Techline at Hyundai was contacted and tech was instructed to install junction box for fuses (91950-K4061 Junction Box assembly I/PNL 91). The car was undriveable on the Crossroads lot until part received and replaced 9/20/2024. 9/24/2024 when I arrived to pick up the car, the service advisor told me the door was left ajar after car wash, causing draw on battery; the battery was damaged by continued discharge due to strain from parts replaced. Hyundai agreed to replace the battery at no charge to customer. There were no warming lamps, messages or other symptoms of the problem prior to 6/17/2024. My safety, as a senior and woman is at risk if the car was stranded in a parking lot or other area outside of my home garage.
NHTSA complaint 11641724I am concerned about the safety of my car and have little faith that there are qualified mechanics who understand EVs and can properly service an EV car. Two times on April 9, 2024 (and on at least 4 other occasions in 2023) while drive at approximately 45 miles an hour on a RI State highway at a safe distance from any care in front of me, my vehicle went into the fail-safe mode while I was driving causing a sudden significant loss of power to the car and it appeared to be that it was going to stall. There was no warning sound indicating that I was going to crash into the forward vehicle (again, I was at a safe distance). In order to continue driving, I had to pull onto the road shoulder, shut off the car, which seemed to reset it. On this particular day/occasion, this situation occurred twice in the span of about 10 minutes. Had there been anyone driving right behind me, they would have hit my car. In addition, I brought my car to the dealer to address but the dealership did not know how to fix/address my problem. They did find "multiple codes" in the car history, deleted the codes, and test drove the car. They said if it happened again, to let them know. They also told me if it occurred again, then I should bring it in when the 1 and only technician, who knows anything about the EV cars, was working. I took a photo of the dashboard immediately after one of the episodes while the car was still running before I shut if off. I will attach it.
NHTSA complaint 11585896We just had our 2020 Kona updated from the dealer with major software and recall updates. Since that point the car has been draining from the 12volt battery on it's own and killing the charging circuit for the battery. It has caused us to have to jump start the car and not be able to keep the 12 volt charged which runs all of the environmentals and car systems. Unless you have a jump pack with you, you have to jump it after every stop. I have tested the battery and it is fine but the system needs a high end initial draw and is not getting it. I have contacted the dealer but they are saying it is not their problem. This needs government address, as it is the same issue in the NHTSA recalls or Hybrid and EV Sonata and Ioniq 5 models.
NHTSA complaint 11580665This has happened about 15 times since I bought my Hyundai Kona EV Ultimate new in February 2021: When a car in front of me slows very quickly, occasionally my car tries to help me too much. I have been in complete control of the situations, but my car beeps it's warning, adds it's efforts and the brakes lock up with tires squealing, and we stop with plenty of space in between myself and the car in front of me. This usually happens in freeway traffic. It is terrifying and I always immediately look in my rearview mirror to see if I'm going to get rear-ended. I haven't been hit yet, though I have been flipped off a few times. One of these days, people will be hurt, along with the damages to the cars. The first time it happened was only about 2 weeks after the purchase. I had my 5-year old twin granddaughters in their car seats. Just as described above, the brakes locked up and it really scared them (me too!). I took it back to the salesman I bought it from at Stevens Creek Hyundai and he said it was just a setting with the response time, so he changed it. But it kept happening intermittently. I brought into the Future Hyundai of Concord dealer and they test drove it, could not replicate it, and after checking with their computers, said that the "system is working as designed". Frustrated that I wasn't being heard, I contacted Hyundai Consumer Affairs. They supported me and I got a case number and another appointment at a different dealer, Dublin Hyundai. This time, I went on the test drive and the technician was able to replicate the situation. At first he said it was a setting, but I said that I didn't care what the setting was, this should never happen. It is very dangerous. He agreed and said he would need to contact "Techline" the next day. But when I tried to find out any information about this conversation, I got only silence. Then I got a message that I could come pick up my car and that "the system is working as designed". Help!
NHTSA complaint 11574761I was driving at about 45mph and my vehicle brakes suddenly stopped responding. The car alarms went crazy and said "regenerative brake failure" which is fine and all, but why the hell would the regent failing impact my ability to stop entirely? I could not get the vehicle to respond by pumping the brakes, so I put my flashers on and rolled into a lot and thankfully didn't kill anyone. Rolled into an uphill spot, thanked the curb, and engaged the ebrake which I'm not sure actually worked. The brake was both firm and soft when pressed. That was terrifying and I was literally just on the freeway.
NHTSA complaint 11543580Braking: When coming to a stop, the vehicle slows as expected. at about 10 MPH or less, while still continuing to apply braking pressure by foot, the vehicle stops braking and a sudden acceleration kick occurs, propelling the vehicle forward an additional 10 feet or so, then the brake kicks in again. Was able to duplicate this issue with a Tech from Hyundai of Moreno Valley riding as a passenger. This is hazardous, because it could result in striking a vehicle or pedestrian in a crosswalk for example.

NHTSA complaint 11446612215/55/R17 The N Priz AH8 tires are extremely slippery on wet pavement. Unless I drive exceptionally slow and cautiously, I could lose control of my Hyundai Kona Ev
NHTSA complaint 11445281When starting the vehicle, the forward collision avoidance system is automatically on, this is the default. I must take the active step of turning it off every time I begin to drive, if I do not wish to use it. The issue is that the avoidance system has several times almost CAUSED me to have an accident and thrown me forward, through sudden and hard breaking if the car thinks I am too close to the vehicle in front of me. This is why I continually turn it off. I would like to point out that I have NEVER rear ended anyone in over 40 years of driving, so rather than truly avoiding any collision, the car causes me to come very close to having an accident, as the sudden and hard braking has caused me to swerve while preparing to pass another vehicle.

NHTSA complaint 11420016Hyundai issued a several recalls that notified me of various updates related to my car battery as well as that I cannot park my car in my garage as battery could catch fire. I have taken my car to a local dealer each time for these software updates as required. They originally did a "fix" for the battery issue back in 2020 but clearly the issue has not been remedied since it first came to light in 3/2019. Then in 3/2021, Hyundai notified me by mail that in addition, I must limit my battery capacity to 80%, prohibiting my use of the car for longer planned trips this spring and summer and likely fall 2021. I have had to change my lifestyle and make other arrangements in order to continue my plans. The battery has a lifetime guarantee and I bought the car due to this guarantee as well as the use of 100% of the battery expected mileage as I have a long commute and take long day trips since this is my only car. The requirement of parking outside my garage for over 6 months now reduces the value of my car as it is subject to intense heat/sun/sandy wind/fire debris as I live in a Southern California desert. Between the reduction in battery change, fire danger of battery, parking outside, the value of my purchase had decreased significantly and it was false advertising when I purchased the car in 11/2019. I would not have purchased this car if I only had 80% of the battery capacity and had to park it outside to avoid possible fire due to charging. Hyundai has only offered $200 to come in to dealer to have then change battery capacity to 80% (which I did . That is not enough compensation for the loss of use, loss of value, loss of car quality from parking outside, and loss of my time. My fear is that they will issue a buyback that does not include the value of my window tinting and specialized lazer fit car mats and deducts value for my mileage. There is not ETA on when the battery will be replaced/fixed at this time - completely unacceptable.
