2022 Hyundai Kona Problems

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 purchased my 2022 Hyundai Kona on August 28, 2024, and I am the first registered owner. Only 48 days after purchase, the vehicle suddenly broke down without warning while stopped at a red light in [XXX] after traveling from [XXX] . The vehicle had to be towed. Since then, the vehicle has repeatedly experienced dangerous engine and timing-related issues despite major repairs, including an engine replacement, timing chain repairs, and multiple dealership inspections. The most dangerous incidents involve sudden power loss and large clouds of smoke while driving. On January 1, 2026, while attempting to pass a semi-truck on a multi-lane highway, the vehicle suddenly lagged, lost acceleration power, and emitted a large cloud of white smoke from the exhaust. This created an extremely unsafe situation because I was actively passing traffic at highway speeds and could have been struck by surrounding vehicles. I have also experienced these failures late at night on busy highways while traveling between [XXX] and [XXX] . In March 2026, the vehicle again emitted a large cloud of smoke and resumed lagging during acceleration. On April 23, 2026, Hyundai of Meridian informed me they personally witnessed the vehicle emit another large cloud of black smoke during test driving. These smoke events can reduce visibility for surrounding drivers and create hazardous roadway conditions. The vehicle has spent approximately 149 days in repair facilities, nearly 24% of the time I have owned it. Multiple dealerships documented timing chain slack, cam timing issues, and major engine concerns. Despite the recurring failures and safety concerns, Hyundai denied replacing the engine again and denied buying back the vehicle. I no longer feel safe operating this vehicle due to the risk of sudden power loss, engine failure, and smoke emissions while driving in traffic.

The vehicle trunk doors pops open. This has been happening for several months. We’ve taken it to the dealership. They said that it was not covered and there has been no recall on this, but it’s still happening and it’s very dangerous. It’s happened on the freeway on the back roads at night it doesn’t matter it just when it feels like it wants to open up it beeps loudly and light comes on the dashboard as something is wrong and It will just pop open.

When I first brought the car for its first service appointment (6 months after purchase), I informed the service dept at the dealership that the car seemed to accelerate itself when I was driving. They said they hit a reset button and that I shouldn't have any more problems. What I found was that the car then drove sluggishly but it did not accelerate anymore. Recently however (2.5 years into the purchase), the car started "sliding" when I hit the break pad. I took the car in again for service a few months ahead of time and they said that my car mat was wedged under the break pad and that was what was causing the car to slide when I hit the break. The car slid but also accelerated by about 5 miles, however I was able to quickly break and stop it without incident. This last service was on Friday, August 1st, and on Sunday August 3, the car slid and accelerated again - without the floor mat being wedged under the break. On Monday morning (August 4th) I called Hyundai so many times that I lost count. I was never able to speak with a service employee but I was given an appointment for a week and half later. According to ChatGPT, it is a common issue with the 2022 Kona and it should be recalled.

While accelerating onto the highway, the engine backfired and suddenly lost speed, violently shaking.

I found a lot of shaved metals when I did the oil change for the Gear Reduction. It made a lot of noises when driving or the wheel of fortune sounds whether the car is in Regenerative Braking. The sounds developed as time goes on but Hyundai failed to recall this issue. I found this has been an ongoing issue since 2019 when Hyundai make this Kona EV, but their engineers didn’t fix this type of issue and continue to manufacture the Kona EV with the same Gear Reduction Assembly and it caused a lot of noises with these shaving metals found in the oil changes. This is abnormal for a GRU to have so many metals found in the oil. Thus, it made a lot of noises. Now my car can’t even drive because of this. The GRU has been broken because of this issue that Hyundai didn’t even fix since 2019.

When I purchased the car with in 2 weeks epb , auto hold and auto stop all 3 lights on dashboard came on orange. Took to dealership and they fixed the problem. 4 months later now the lights are back on.

I believe was sold a lemon car I purchased from carmax.

22’ Kona N DCT Base US spec. 5,600 miles est (2nd Kona) Fuel used: Shell Premium Outside Temp: 76F/Dry-Clear Sky. This is my 2nd Kona N, this is the 4th experience I’ve had with my Kona N’s. Towed the first on Vin# [XXX] to dealer, engine stalled after refueling during a road trip. 6/7k miles. Misfire. No replaced parts, car started acting normal. Then I traded it in for another Kona N in June 22’. The vehicle in normal mode is fine. I believe. Switching from N Mode is where the engine starts misfiring and runs on 3,2cyl puffing out white smoke. Leaving me stranded. The codes all show via car touch screen, and OBD reader/history. All electronics perform properly, including active safety features. I am Hyundai affiliated but I do not know how to relay the message. All of the Kona N/Elantra N/Veloster N DCT. Need software updates. It’s a bug, I honestly think. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

My vehicle keeps shutting off with no warning and has almost killed me on multiple occasions The dealership keeps placating me about getting it fixed, saying that a repair is months out Meanwhile, I am driving a very dangerous vehicle that shuts off and shakes like it’s going to explode

The low bean headlights are where the Brights should shine. The brights shine in the tree tops. Every time I go out at night I get flashed by almost all passing cars when the low beams are on. The dealership told us there is no way to adjust the lights. How am I supposed to drive this at night?

The tread came off the tire on the highway causing me to crash off I 75. The tires were made 6 of 2025 and the pressure was 31.5 according to the highway patrol officer on scene. I have the paperwork for the tires I purchased at Sams Club in Cape Coral Florida on 7/29/25. The tires are less than 11 months old and this shouldn't have happened. The tread damaged multiple parts of my car.

Pirelli P Zero 235 / 40 R19 96Y Purchased a 2022 Hyundai Kona N on 7/23/22. At 8ooo miles all 4 tires are cracking on side wall and tread area. Hyundai said those tires are not to be driven on if the outside temperature is 40 degrees or lower. We currently live in Joplin Missouri. When we purchased the vehicle we were not informed about the situation with the tires and temperature. The warranty on the Hyundai website stated the tires should last for 30,000 miles. All 4 tires need to be replaced, if we knew about this issue we would have made arrangements, prior to the purchase, to have different tires placed on the vehicle. We feel that we have been taken advantage of due to the lack of information on Hyundai’s part. On 4/7/23 I contacted Hyundai and was told to take the vehicle to a Hyundai dealer and have the tires inspected. On 4/10/23 we took the vehicle to the Hyundai dealer and they inspected the tires and recommended that they be replaced and they would send a complaint to Hyundai. The service manager at Fletcher Hyundai, Zeb Nageotte 417-434-1601, said he has never seen anything like that before in that little time.

I was rear ended waiting for the car in front of me to turn. Driver was going between 33-40 on a residential. My air bags did not deploy.

During collision, airbags did not deploy. In attempt to avoid collision, automatic breaks failed and did not stop the vehicle, cruise control continued to attempt to drive the vehicle despite collision warning and did not stop- coupled with my manual breaking, the car did not stop. Car is currently at a tow lot waiting for insurance. My safety was put at risk due to airbags not deploying during serious collision, the breaks malfunctioned. At this time, the car is in the beginning stages of insurance. My car did not display any prior failure features.
