  The vehicle is a 2022 Hyundai Kona N Line, VIN [XXX]. The driver-assistance/safety systems have intermittently malfunctioned. The reported problems include false forward-collision warnings, unintended automatic emergency braking when there is no apparent obstacle or collision threat, false blind-spot/side warnings, and unwanted steering intervention from the lane-assist system. The exact failed component is UNKNOWN. Possible involved systems include the Forward Collision-Avoidance Assist system, Lane Keeping/Lane Following Assist, Blind-Spot Collision Warning/Collision-Avoidance Assist, related cameras/radar sensors, control modules, wiring, or software. The vehicle remains available for inspection upon request. These malfunctions create a serious crash risk because the vehicle may unexpectedly brake or steer while traveling at highway speed. Three different drivers in my household have independently experienced abnormal behavior from these systems. My greatest concern is that sudden braking or steering intervention could cause the vehicle to be struck from behind, leave its lane, enter another lane, or collide with another vehicle or fixed object. The vehicle was taken to AutoFair Hyundai for inspection and diagnosis. The dealership stated that it could not reproduce the condition during its evaluation and did not find a stored diagnostic trouble code. The dealership therefore did not identify a specific cause or perform a repair directed at the reported forward-collision, blind-spot, braking, or steering malfunction. A rocker cover assembly was replaced under warranty for a separate issue. The dealership has stated that it is checking whether the affected driver-assistance systems can be permanently disabled. Hyundai Motor America has also been notified through a national customer-care case. Hyundai is aware that the complaint remains unresolved. There are not always warning lamps or stored fault codes associated with the events. The symptoms are INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION

  I purchased this 2022 Hyundai Kona used in May 2025 with approximately 55,000 miles. Within about one to two months of purchase, in June 2025, the transmission began to malfunction. When I pressed the accelerator, the speedometer and engine speed would climb but the vehicle would not accelerate, resulting in a sudden loss of acceleration while driving. This happened in traffic on a public road, which put me at serious risk of being rear-ended and left me unable to safely merge, cross intersections, or maintain speed. The vehicle was taken to a Hyundai dealership service center, which diagnosed a transmission failure and performed a transmission repair in August 2025. In October 2026, about 14 months after that repair and about 17 months after I purchased the vehicle, the exact same symptom returned. When accelerating, the speedometer surges while the vehicle fails to accelerate and loses drive. This has again occurred on public roads. The vehicle now has approximately 78,000 miles. This is a serious safety concern, not only for me but for everyone driving around me. The loss of acceleration is sudden and unpredictable, and it occurs while the vehicle is in motion, including in traffic. It puts the driver and surrounding vehicles at risk of a collision. I have stopped driving the vehicle until it is repaired. Warning signs: No warning lights or messages appeared before the failure. The first symptom was the speedometer surging with no corresponding acceleration. Confirmation and inspection: The first failure was diagnosed and repaired by a Hyundai dealership service center in August 2025. The current failure will be taken to the same service center for diagnosis. The vehicle and transmission are available for inspection. I am reporting this because the same symptom has led to transmission failure twice in only about 17 months of ownership.

  Today, my Kona tried to kill me. I was traveling on a freeway in a construction zone. Road conditions were clear: no fog, precipitation, potholes or obstructions. Traffic slowed down to 30 mph as the rightmost lane becomes an exit only lane (and people exchanged between the middle and right lane). Traffic continued to flow freely around 50 mph in the left lane. I was in the middle lane, and after passing the off ramp my lane was clear for at least an eighth of a mile ahead (all visible traffic in front of me had taken the exit). I began to accelerate back up to freeway speeds when the "Automatic Emergency Braking" engaged for no reason. There was a curved driving path on the display (which read "Automatic Emergency Braking"), and it seemed like the car was trying to force me into the left lane (underneath a semi truck). I could feel the same motored pull that the Kona has while using the "lane keeping assistance" feature. But unlike the lane assist which takes 20 pounds to manually override, this took approximately 80 pounds of force to fight. Even fighting the turn, I was multiple feet into the left lane. The only reason I was not crushed by the wheels of the semi trailer is because the driver was hugging the left side of their lane. I was nearly rear-ended and the 4 cars behind me nearly had a pile-up because of this as well. My best guess is that it detected the cement barrier along the side of the curved road and incorrectly determined that I was on a collision path with it. Since it was a construction zone, the cement barrier was approximately 3 feet outside of the lane. In reality, this feature is not production ready and needs to be fixed/removed from the fleet.

  My radiator has coolant leak. I noticed the fluid getting low and the smell. I had to put fluid in 2-3 times the last month. I took it into the shop and they confirmed that it is the lower left part of the radiator that it’s leaking from and it has to get replaced. I did notice on a campaign 24\-EM\-005H\. for the Hyundai Kona 2022. But my VIN number wasn’t part of that. It is having the same leak and I have to get the radiator replaced. My car has 65000 miles on it so it wasn’t covered under warranty. It is in the auto shop now and will cost me over 1200 to get it fixed.

  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.

  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.

  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.

  The National Highway Traffic Safety Administration (NHTSA) received a letter dated July 13, 2022, petitioning the Agency to initiate a safety defect investigation into loss of motive power allegations attributed to oil drain pan assembly failures on certain Hyundai Motor America, Inc. and Kia America, Inc. vehicles spanning Model Years (MY) 2005-2021. The Petitioners cited examples of complaints indicating that the subject vehicles were experiencing rapid loss of engine oil due to oil drain plug back outs, resulting in loss of motive power and/or catastrophic engine damage. Additional complaints were provided which alleged that the oil drain pans lack sufficient structural integrity and are susceptible to cracking. The petition itself can be reviewed at NHTSA.gov under ODI number 11481745. On September 12, 2022, the Office of Defects Investigation (ODI) opened Defect Petition (DP22-003) to evaluate the Petitioners’ request. The Petitioners have provided additional complaints within four supplemental letters dated January 31, 2023, March 21, 2023, May 23, 2023, and August 4, 2023. ODI’s evaluation included the review and analysis of the complaints and supporting information submitted by the Petitioners, as well as additional complaints submitted directly to NHTSA which referenced either the oil drain plug or a crack in the oil pan. After reviewing the available data, ODI has not identified evidence that would support opening a defect investigation into the oil drain pan assemblies of the subject vehicles. Based on a review of the available information, a loss of motive power resulting from an oil drain plug back out has not occurred between the initial sale of a vehicle and the completion of its first oil change. If during an oil change service, a technician fails to remove the existing drain plug gasket before installing a new gasket, it is likely that a proper seal between the drain plug and the oil pan will not be made. An improper seal between the drain plug and oil pan could lead to the backing out on the drain plug, resulting in the sudden loss of oil while driving. Additionally, the provided examples of oil pan cracks were localized to the immediate vicinity of the oil drain plug and/or appeared to be the result of direct-contact with a tool during servicing.  There is no information to support that a vehicle-based defect exists relating to the oil pan assembly, and instead the documented incidents are related to the failure to follow the proper maintenance procedures during oil change service. In October 2023, Hyundai published a Technical Service Bulletin (TSB) that provided detailed instructions for oil change service on its gasoline powered vehicles, specifically highlighting the need to remove and replace the existing drain plug gasket prior to reinstalling the drain plug. After a thorough review of the material submitted by the petitioner, the information already in NHTSA's possession, and the potential risks to motor vehicle safety implicated by the petitioners' allegations, NHTSA does not believe that a formal investigation is warranted. Therefore, the petition is denied. A Federal Register Notice (FRN) further detailing NHTSA’s reasons for denial of the petition will be published. The reference numbers for the complaints to NHTSA cited by the petitioner can be found in the petition submission documents in the public file for DP22-003. To review those complaints and the additional complaints ODI added to its evaluation which are cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.
