I received the recall, brought the Kona in had the software download. Now the engine code indicates engine issues with the safety code. Hyundai customer service representatives stars because the issue wasn't found and the software download completed this doesn't fall under the recall. I do have an appointment to bring the Kona into the dealership but because Hyundai states it is no longer under the recall I am responsible for the towing and will not be remembursed. When I initially brought the vehicle in I was told if the pistons and engine codes appears under the recall layer on towing and replacement of the engine is covered. I was also told my engine covered up to 150,000 miles. Even through I only have 65,000 Hyndai dealer and customer service stated it is not as this is only if the engine showed signs at the time of the software download. This is absolutely wrong to be treated like this and been advised by my local mechanic this does appear to be part of the recall, will deregulate, or engine could seize up causing a safety issue.

I am filing a safety complaint against Scott Stark’s South Point Hyundai for selling me a vehicle with an active open safety recall, a blown transmission, an A/C failure, and a dry-rotted tire. Before returning the car for service under a promised 1,000-mile warranty, my sister, who has worked for Corporate Hyundai for 15 years, helped me conduct a full intake baseline inspection at her dealership. We performed a recorded 360-degree video inspection, took high-resolution photos of every square inch, and ran full computer diagnostics, which confirmed zero tool marks on any bolts under the hood or on the transmission, and all diagnostic readings were perfectly recorded. South Point Hyundai kept my vehicle for 10 days for repairs, making excuses about test drives and failing to find technicians. However, a hidden GPS tracker tucked deep under my passenger side carpet meticulously documented every single time the vehicle moved or remained completely stationary on their lot. Upon picking up the vehicle, my sister scanned the car immediately with her diagnostic computer. The readings are now completely erratic and all over the place compared to the baseline corporate readings we documented 10 days prior. Physical inspection reveals that bolts have been turned, internal components have been actively tampered with, and parts have been structurally altered. The evidence directly indicates that this dealership used my personal vehicle as an unauthorized parts donor vehicle to harvest components, severely compromising its mechanical integrity, structural reliability, and overall road safety. This severe tampering has left the vehicle completely unsafe to operate. We possess full video evidence, high-resolution photographs, GPS tracking logs, and comparative corporate Hyundai diagnostic data verifying this severe mechanical fraud. I have turned this info over to Corporate Hyundai, the DMV, and federal enforcement agencies due to safety risks.

The contact owns a 2020 Hyunndai Kona. The contact stated while attempting to start the vehicle, the check engine warning light illuminated. The contact's fiance, who is an independent mechanic attached the portable diagnostic tester to the vehicle, and the failure code was P1327. The dealer was made aware of the failure but provided no assistance. The contact was informed that the repair was not covered under warranty. The contact referenced an unknown recall; however, the VIN was not associated with a recall related to the failure. The manufacturer was made aware of the failure and a case was filed. The contact as advised to take the vehicle to the dealer for diagnostic testing. The failure mileage was approximately 117,000.

I am receiving an intermittent "check regenerative brake" message. The message will clear automatically and then reappear every three to four weeks. An internet search reveals this is a common error for the Kona. Most people report no repair by the dealer. In several cases, the brakes stopped working, resulting in collisions. The hydraulic breaks do not work if the regenerative brake system fails leaving you with no way to stop the car. The manufacture has no solution.

2020 Hyundai Kona, ~36,300 miles. Driver's side door latch assembly. On or around May 9, 2026, an abnormal mechanical noise began coming from inside the driver's door whenever the key fob lock/unlock button was pressed, consistent with a failing latch actuator. I booked a service appointment, and on May 15, 2026, an authorized Hyundai dealership confirmed the defect and recommended full replacement of the driver's door latch assembly. The vehicle is available for inspection. A latch that does not reliably operate is a serious safety risk. The driver's door is the primary egress point. An intermittent or inoperative latch could prevent emergency exit, block post-collision egress, or prevent first-responder access. The vehicle regularly transports children, increasing the consequence of any failure. No dashboard warning lights, alerts, or messages preceded the failure. This is a mechanical defect that does not trigger electronic warnings. Hyundai TSB 21-BD-006H (May 2021) acknowledges this exact failure mode — door handle inoperative or requiring repeated attempts to open — on the Elantra (AD/ADa) and Tucson (TL). The remedy is full latch assembly replacement, and Hyundai extended warranty coverage on the latch to 10 years / unlimited miles on those models. The 2020 Kona is not named in 21-BD-006H despite exhibiting the identical failure mode at low mileage on a 6-year-old vehicle. The defect appears to extend to the Kona platform and is not currently covered. Vehicle has not been inspected by Hyundai corporate, police, insurance, or independent shops. Filing this complaint to record the cross-platform defect pattern and request that NHTSA evaluate whether the door latch warranty extension should be expanded to include the Kona.

The vehicle all shut off as I slowed down for a stop sign. Put in Park turn the key off restarted it got to the next stop sign same thing. Also the red light same had to shut it off put it in put in Park shut off and then restart and step on the gas so I can get through before a car hit me. Happened several times till I finally got the car home done it started knocking loudly and shut off just as I got into my driveway. Check the oil. The oil is fine. Occasionally the oil light would come on if you put in Dr.. It is knocking really loud. The engine light keeps flashing constantly. I called Brown Dobb Hyundai in Easton Pennsylvania. They told me this recall has nothing to do with my car because of the VIN number. But everything that is happening to it is is under recall 187. But because of the VIN number they are insisting it’s not my car. What can I do before I get in an accident? I don’t have any other cars to rely on. I have a son with Autism and I am a single mother. What else can I do? I had this car not even three months.

Engine light comes on starts flashing as well as the oil light occasionally. If you slow down or have to stop it completely shuts down you have to put in park and restart the car to get anywhere and start stopping in front in the middle of traffic. So if you slow down to go up a hill or anything, it just stops completely. Also making a clicking or grinding sound not sure.

On February 27, 2026, my 2020 Hyundai Kona (Recall 203) suffered a catastrophic engine stall while driving, requiring an emergency tow. The dealership (Rosen Hyundai) and Hyundai Motor America are refusing to perform the Safety Recall 203 remedy unless I first pay $4,715.26 for a timing repair. I was also required to pay $453.05 for wiring repairs just to "enable" the recall test, yet the recall remains unaddressed because of a financial paywall. I am reporting an obstruction of a federal safety recall by the manufacturer.

The contact owns a 2020 Hyundai Kona. The contact stated that during a regular maintenance visit, the contact was informed that there was a leak coming from the front axle transfer case, which was initially unrepaired. The vehicle was subsequently taken to a dealer in Colorado, where the seal was replaced. However, while an oil change service was being performed later, it was discovered that the failure recurred because the previous repair was performed incorrectly. The first failure was for an inoperable seal, and the second failure was due to an improper repair. The third inspection confirmed that the seal had not been installed correctly during the prior service. The dealer was notified of the failure. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 146,000.

On 3/29/26 my Kona caught fire while parked in the front left side of the engine and burned completely within eight minutes. This is not an electric car. Prior to that I drove the car all day with no incident. It was later in the evening around 5:40 PM. I had driven from my house to a restaurant which is about 6.8 miles from my house. I parked my car and then my son-in-law noticed that my engine was smoking. My husband went to check to see if it was the radiator, but he noticed that it was fire and we called [XXX] . I know there are no recalls for my car, but I wanted to report it to you. The car only had 44,900 miles on it and was only serviced by West Nyack Hyundai. The last service was on 1/19/26.

My car was taken in as a part of recall bulletin 203 for improperly heated piston rings treated pistons rings that result in premature engine failure and possible fire on 12/5/25. The knock sensor test was performed and the KSDS software was installed. On 3/12/26 my daughter who was on the way home from a trip called because her checking engine light started flashing and the engine was knocking. We had it towed to Hyundai and they are denying service under the recall stating improper codes yet one of the codes is P1327 KSDS detection which is related to the rod bearing failure the car currently has. They are trying to make me pay $4600 out of pocket plus the tow bill when this is directly related to the recall.

My 2020 Hyundai Kona (VIN: [XXX] ) has a persistent engine stalling safety defect that matches Recall 203 (22-01-042H, NHTSA Campaign 21V301000 – Nu 2.0L Atkinson Engine Inspection and Replacement). The recall addresses improperly heat-treated piston oil rings causing cylinder bore scuffing, accelerated oil consumption, abnormal knocking, and potential engine stall while driving (increasing crash/fire risk).I first brought the vehicle to Corona Hyundai for repeated stalling while driving. They performed the recall vibration inspection and software update (Campaign 974), stated the test passed, and declared the vehicle "fixed", safe and "good-to-go" Immediately after pickup, the stalling returned worse: approximately 60-80 miles later on XX near the XXX exit (four-lane high-speed highway), the engine completely stalled at 65 mph while merging for an exit. This caused vehicles and semi-trucks behind me to swerve dangerously and very nearly collide with me. The vehicle stalled four more times on the way to my destination in [XXX] .I then took it to the nearest dealer, Carlsbad Hyundai for safety reasons. They performed the vibration inspection again, which also "passed," yet the real-world symptoms would continue unchanged: accelerated oil consumption (I monitor the dipstick and refill regularly), sputtering, knocking noises, and complete engine stalls (dozens of incidents, especially on local roads and turns). The vehicle remains undrivable due to imminent stall risk while moving and putting myself, my passengers and other commuters at high risk of severe injury or death.Both dealers and Hyundai Customer Care (Case #XXX) have refused further action, stating the vibration test passed, they cannot duplicate the concern, and no additional claim can be submitted for engine replacement. Hyundai's TSB [XXX] requires only the vibration inspection; engine replacement is authorized if "NO PASS" – no separate oil consumption test or monitored drive INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.

The contact owns a 2020 Hyundai Kona. While the contact’s son was driving the vehicle on the highway at an undisclosed speed, there was a knocking sound coming from the engine and the vehicle failed to stop as intended. The gear shifter was shifted into neutral(N) and restarted; however, the engine failed shortly afterwards, and the vehicle was unable to restart. No warning lights were illuminated. The vehicle was towed to an independent mechanic, where it was diagnosed with piston rings failure and low engine oil. The vehicle was not repaired. The manufacturer was notified of the failure, where it was confirmed that the VIN was included in NHTSA Campaign Number: 21V301000 (Engine); however, the recall repair was already performed. The approximate failure mileage was 108,000.

many times a year, without warning, vehicle dash lights turn off and light up like a christmas tree, followed by fca warning sound and lights going off, and a loud mechanical thud. Lose engine throttle going highway speeds. This can occur at nearly any speed without warning. Car must be powered off and back on to get normalcy.

While driving under normal conditions, the vehicle’s dual-clutch transmission (DCT) failed to engage properly, causing a sudden and unexpected loss of propulsion. When the accelerator was pressed, the vehicle hesitated and did not respond as commanded, resulting in delayed or no acceleration. This occurred while driving in traffic at approximately 30 mph while trying to acceletate to merge onto highway and has happened multiple times. In some instances, the vehicle appeared to remain in gear but would not accelerate, and in other instances the transmission disengaged before re-engaging unpredictably. This created an unsafe situation, as the vehicle could not maintain speed or merge safely, significantly increasing the risk of a collision, especially in traffic or at intersections. The issue occurred without sufficient warning and continues to happen intermittently during normal driving.The vehicle was inspected by a dealership, which stated the condition is related to a clutch issue within the dual-clutch transmission and acknowledged it is a known issue affecting this transmission. The dealership further stated the issue would not be repaired because the vehicle is out of warranty.

the headlights in this model Kona keep burning out after 9 months or so. I have replaced them multiple times in the last 5 years on both left and right sides. I use glove to put in the bulbs and are very careful not to let my hands touch the bulb. I have never had this happen with any other car I have owned. I suspect an electrical system issue, or perhaps wiring, but that is speculation. I have not had this inspected by the dealership. The latest date of failure is listed below.

The timing system was repaired in February 2025. After similar symptoms of vehicle stalling, the check engine light came on Found a software update that needed to be completed to determine if engine needed replaced. Dealership has refused for seven weeks to complete the entire job of the update which includes running a diagnostic of codes. Instead, they have been arguing that the timing system needs replaced and not providing the codes from the safety software update. Obviously there's a much deeper issue if the timing system keeps breaking down.

When driving up inclines at low speeds (<10 mph), the vehicle shakes and stutters on the verge of shutting off. This happened twice on [XXX]. I experienced a full vehicle shut off on [XXX} while the vehicle was stationary, but shifted into drive . In August, the vehicle stuttered and shook before shutting off.

Vehicle suddenly began shutting off upon braking and/or acceleration at any speed, idling very hard, and/or barely starting or dying immediately after starting and making a very loud whining noise while driving on an interstate. A mechanic ran a diagnostic test on it and determined that it was a P1327 code and recommended it be taken to dealership for full engine failure. This particular code was known by Hyundai to occur on certain models and years, including Kona 2019-2021, as early as 2022 and while a recall campaign was initiated, no recall to date has been issued. No warning indicators on dash occurred in advance or even after the vehicle began malfunctioning (i.e., no check engine indicator, etc.). Vehicle is available at dealership upon request.
