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.

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.

Recall with car regarding coolant. Last year Hyundai apparently addressed; however, coolant light came on, despite coolant being full. Told by different dealership that with these issues, it needs to be checked and rechecked multiple times; otherwise, issues arise again (as in my case). Want this addressed by dealership. They are charging me a diagnostic fee of $198. Previously, when brought car in for recall work, equipment not always working.

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.

In January 2026, my engine light illuminated and the vehicle lost power. The dealership found a sudden loss of compression across all four cylinders, requiring a total engine replacement. This occurred without warning, only two months after a routine oil change at the same facility where no issues were reported. Despite opening a case with Hyundai corporate, there has been no progress. My research indicates that while NHTSA Recall 21V301 (Safety Recall 203) specifies 2019–2021 models, the 2022 model shares the same engine design and identical reports of stalling and compression loss. My vehicle has been at the dealership for three months with no resolution. The dealership says they are running tests requested by tech line without providing documentation of the tests or the results. Although, the initial test performed indicated that it was a compression ring issue.

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.

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.

I had the radiator replaced by the Ourisman Hyundai Laurel dealership on 10/1/25. Radiator replacement was under warranty. On 10/4/25car overheated while driving. I pulled the car over and called for a tow truck. Car was leaking lots of coolant. Brought it to service center at Ourisman Hyundai Laurel, they stated “the hose to the thermostat was not all the way on. Put hose on correctly no more leaking.” On 10/15/25 multiple lights came on the dashboard including the master warning light. Took car to Ourisman Hyundai Laurel again; received the car back, dealership stated “ TECH COULD NOT DUPLICATE THE LIGHTS POPPING ON DASHBOARD. UPON FURTHER DIAGNOSIS TECH FOUND THAT THERE WAS A CONNECTOR NOT GETTING THE PROPER CONTACT TO COIL NUMBER 1 TECH RECONNECTED THE CONNECTOR AND TEST DROVE THE VEHICLE FOR 5 MILES. NO CONCERNS PRESENT AT THIS TIME.” On 10/20 I brought the car in to Ourisman Hyundai Laurel again because Electronic Stability Control light as well as ABS warning light and several other warning lights came on multiple times. Ourisman Hyundai Laurel service technician said they could not duplicate the problem and there is nothing they can do. This is a safety issue because it concerns the electronic stability control and brakes.

The horn on my 2022 Hyundai Kona has failed multiple times. It has been replaced twice already, and it has stopped working again at around 65,000 miles. This is a serious safety concern as I am unable to alert other drivers in emergency situations. The repeated failure of the horn suggests a possible defect in the electrical system or horn assembly. I am requesting an investigation into this issue.

On Saturday, [XXX], while driving on the highway, the oil plug on my vehicle suddenly fell out, causing all the oil to drain rapidly. This created an extreme safety hazard not only for myself but also for other drivers on the road. I did not notice the oil spillage until the oil light on the dash appeared. At the time, I was in the leftmost lane traveling at highway speeds, so I could not stop immediately. I had to carefully veer across five lanes of traffic and navigate out of a construction zone before I was able to pull over safely. The engine lost lubrication during this process, and I was forced to have the vehicle towed to Ed Napleton Hyundai in Hazelwood, the same dealership where I purchased and serviced the car, for inspection and repairs. This incident occurred just three weeks after I had an oil change performed at the same dealership. I have been attempting to contact the dealership for updates on the status of my vehicle and the investigation into potential engine damage for the past three days, but I have received limited information until today, when the service manager, Jerry, stated that they installed a new plug and added oil, and since it's not ticking, it's okay. However, having worked in the automotive industry for years, I know that a full teardown is necessary to properly check for damage, including inspecting the bearings, rings, cylinder walls, and turbo for signs of oil starvation. This service was not performed. Additionally, Jerry informed me that speaking to someone higher up would do absolutely nothing for me. This is not an isolated issue. Over the course of my ownership, the dealership has damaged my oil filter by over-tightening and stripping it on two separate occasions during routine maintenance, requiring me to return to the facility each time. On both instances, I had to wait an additional 2 to 3 hours while they installed replacement parts to correct their errors.

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.
