2020 Hyundai Kona

Defect. Hyundai Motor America (Hyundai) is recalling certain 2019-2020 Elantra, 2019-2021 Kona and Veloster vehicles equipped with 2.0L Nu MPI engines. The piston oil rings may not have been properly heat-treated, which could result in engine damage.

Risk. A damaged engine may stall, increasing the risk of a crash. In addition, oil may leak onto hot exhaust components, increasing the risk of a fire.

Remedy. Dealers will inspect and, if necessary, replace the engine, free of charge. In addition, Hyundai will deploy Piston Ring Noise Sensing System (PNSS) software. Owner notification letters were mailed August 24, 2021. Owners may contact Hyundai customer service at 1-855-371-9460.

Defect. Hyundai Motor America (Hyundai) is recalling certain 2020 Kona vehicles. The certification label may indicate incorrect Gross Axle Weight Rating (GAWR). As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) numbers 567, "Certification" and 110, "Tire Selection and Rims."

Risk. An incorrect GAWR could result in the vehicle being overloaded, increasing the risk of a crash.

Remedy. Hyundai will notify owners, and dealers will install new label stickers displaying the correct GAWR over the affected areas of the certification label, free of charge. The recall began March 2, 2020. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's number for this recall is 187.

My 2020 Kona 2.OL failed an oil test losing 2.5 quarts in 960 miles, stalled on the highway, and blows oil out the tailpipe. Hyundai (Case #43141313) is denying repair coverage because my VIN was excluded from Recall 21V301000. This recall needs to be expanded to include my VIN.

The contact owns a 2020 Hyundai Kona. The contact stated that while driving at 35 MPH, the accelerator pedal was depressed, but the vehicle hesitated, and there was white smoke coming from the exhaust. The vehicle was towed to an independent mechanic, where the contact was advised to take the vehicle to a dealer. The dealer was made aware of the failure. 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. The failure mileage was approximately 53,976.

COMPONENT THAT FAILED: The engine short block piston rings (related to NHTSA recall 203) failed, causing severe cylinder wall scoring. The vehicle is currently located at an authorized Hyundai dealership and is available for manufacturer or NHTSA inspection. SAFETY RISK; The defective piston rings caused severe internal oil consumption, resulting in hydraulic oil starvation. This creates a high risk of sudden engine stalling, catastrophic engine seizure, and complete loss of motive power while driving in traffic. CONFIRMATION AND INSPECTION: Yes, the defect has been confirmed. The current Hyundai dealership performed a boroscope inspection, which physically confirmed severe vertical metal scoring in cylinder 3. They also documented that the engine was 1.5q low on oil with zero external leaks, confirming internal consumption. Despite physical proof of the recall defect, the manufacturer is currently refusing to honor the recall repair. WARNING LAMPS/SYMPTOMS: The check engine light illuminated, logging exhaust camshaft timing correlation codes (P0017). This first April 2026 at 169,000 miles. This timing code is a secondary hydraulic symptom caused by the severe internal oil starvation originating from priary lower block cylinder scoring defect.

I was fortunate to check my daughter's oil and noticed that it was almost empty. I alerted the dealer because I recently got an oil change and thought there was a leak, but no oil was on the driveway. The dealer performed an oil consumption test. They said it was 1 quart per 1,000 miles and this is acceptable. There are other models that are on the recall list, but mine is not. The dealer and Hyundai said that they will not pay for repairs because it is out of warranty. The bigger issue here is that Hyundai is aware of this issue (oil burning fast in these vehicles) and they are not warning owners to check their oil. This is a cute car and it is driven by college age girls who do not think about checking oil. If the oil runs dry, the engine can seize up and the car will stop. This can cause an accident and possible fatality. I am very concerned about the safety of my daughter and others. I have 5 quarts of oil in my daughters trunk to top it off regularly. This information needs to be given to owners of these vehicles to increase awareness of the problem an prevent a tragedy.

The contact owns a 2020 Hyundai Kona. The vehicle was taken to the dealer to be repaired under NHTSA Campaign Number: 21V301000 (Engine); however, the dealer was unable to perform the recall repair because the vehicle had not experienced a failure associated with the recall and there were no fault codes displayed or retrieved associated with the recall. However, an independent mechanic recommended that the engine be replaced. The contact provided the dealer with the fault codes and the failures that the independent mechanic had found; however, the dealer was unable to retrieve the same fault codes. The contact stated that the check engine warning light was illuminated. The manufacturer was notified of the failure and agreed with the dealer and refused additional assistance. The vehicle was not repaired.

The contact owns a 2020 Hyundai Kona. The contact stated that the vehicle was repaired under NHTSA Campaign Number: 21V301000 (Engine); however, the recall repair failed to prevent the failure from occurring. The contact stated that while driving at various speeds, the vehicle lost motive power and failed to restart using the ignition key. The vehicle was towed to a dealer, Capital Hyundai of Greensboro (801 E Bessemer Ave, Greensboro, NC 27405), where it remained for further diagnosis. The contact stated that during the prior recall repair, the Continuously Variable Valve Timing (CVVT) assembly, Engine Control Module (ECM), and Body Control Module (BCM) were replaced, a solenoid was installed, and the engine was inspected but not replaced. The manufacturer was notified of the failure, and a case was opened. The failure mileage was approximately 72,000.

Leaking oil...burns exceptionally fast even with dealership services. Pistons not sealed, melts new spark plugs, misfire on cylinder 3

My 2020 Hyundai Kona experienced an engine-related malfunction. An authorized Hyundai dealer inspected the vehicle, confirmed diagnostic code P1327, and determined that the complete engine required replacement. Hyundai authorized the replacement, and the vehicle remained out of service for approximately two weeks. The engine defect created a safety concern because an engine malfunction could cause reduced or complete loss of motive power while driving, increasing the risk of a crash. The dealer inspected and removed the original engine; I do not know whether it remains available for further inspection, but the repair order and diagnostic records are available. I am filing this complaint so NHTSA can document this engine failure and determine whether it is related to NHTSA Campaign 21V301 / Hyundai Recall 203 and whether additional investigation or corrective action is warranted.

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 c

The Kona was driven a 1/2 hour before parking the vehicle. The Kona was turned off. Within 5 minutes smoke began wafting from under the hood. When I opened the hood to inspect I found the engine & underside of the hood was engulfed in flames. I closed the hood immediately. The Kona fully ignited with minor explosions & burnt completely to the metal frame within 25 minutes.

The car failed to accelerate on highway on multiple occasions, including when slowing down and then trying to accelerate when pulling out on highways.

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 b

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.

I stopped my car foot on brake put it in park and it accelerated on its own and forced me to crash into a concrete wall still not wanting to stop

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.

Basically normal driving the car stalled. It slowed to a stall. I had to restart the car. This has happened a couple to times.

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. If you have any questions, you can email me at [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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 movi

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. This puts me, everyone in the car and everyone on the highway at risk. Dealership was not able to reproduce or pull error codes.

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.

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.

The vehicle has ~51K miles. It has been maintained according to the manufacturer's recommended repair schedule. At low speeds (<10 mph) or when coming from a full stop the vehicle hard shifts. 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. I have reported three instances of this issue to my local Hyundai dealership. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The engine shut down when the car stops at a red light or stop sign. There are metal shavings in the oil due to issues with the pistons.

Car keeps stalling no matter what speed you're driving. Took the car to NTB and they said nothing is wrong with it. It continues to happen even in busy highways where someone almost ran into the back of me. Not safe to drive. Concerned as numerous forums suggest this is a problem with 2019-2021 Hyundai Konas.

The contact owns a 2020 Hyundai Kona. The contact stated that the vehicle was consuming an excessive amount of engine oil. There was no warning light illuminated. The vehicle was taken to a local dealer, where the vehicle was diagnosed, and the contact was informed that the turbocharger was faulty and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 65,000.

I purchased a used 2020 Hyundai Kona with the Nu 2.0L engine. I drove the vehicle regularly without issue for several years, including two days before the incident. On the day of the incident, I attempted to start the vehicle but it ran irregularly. I shut off the vehicle after a few seconds and restarted. The vehicle stalled seconds after starting. On subsequent attempts it failed to start at all. I learned of Recall 203 (defective piston rings), which affects this model year and engine. I contacted Hyundai, who recommended I visit a dealer. Upon inspection, the dealer recommended engine replacement. Hyundai denied engine replacement under Recall 203, on the grounds that the recall was "closed" during an inspection in 2021 (prior to my ownership) despite the defective part not being replaced. This engine, with defective and recalled part, has now experienced sudden and unexpected failure. Hyundai has been uncooperative and I have been without a vehicle for nearly a month.

Ignition, speed and driving halts. I've had this Kona repaired a couple years ago and it took about 6-8mos to get my vehicle back, the this year 2025 the vehicle again is giving me problems. I thought of applying the lemon law however the week of the 6-8months being in the repair shop, I got the vehicle back, and the owner(mr. Crisostomo was very kind and understanding) so it made me be more patience nonetheless there's only so much he could do if he is not the one repairing the vehicle. I was offered carpets for my patience yet still have not gotten them and feel like a bother when I call to inquiry about them and it's not the service manager that I talk to , I feel otherwise. That could just be me, however I know good customer service if it's presence. For the actually year, I would need to check emails and records. But it's probably the year after so 2022 ( almost certain) now, This year, 2025.. I see that there is a recall that the dealership did not inform me. The vehicle is paid of last year, because I was going to relocate but that had changed. I found out about the recall cause my dad had died and step mother is using my other car so I'm using the Kona much more that 3 days a week. I keep dying out in one (1) day.. I died out twice. So I checked if there's a recall and there is. I would like my vehicle repurchased or credit for the amount purchased or I like a jeep 2 door ( is fine) as a recovery vehicle, thank you.

The contact owns a 2020 Hyundai Kona. The contact stated that while operating the vehicle, there was a knocking sound coming from the engine compartment. The vehicle was taken to the local dealer, who replaced the turbocharger, but the failure persisted. The contact stated that the vehicle was consuming an excessive amount of engine oil. The vehicle was later examined by an independent mechanic who determined that the pistons were faulty. No further information was available. The vehicle was not yet repaired. The manufacturer and local dealer were notified of the failures. The contact was informed that the VIN was not included in NHTSA Campaign Number: 21V301000 (ENGINE). The contact stated that the vehicle had experienced the failure listed in the recall. The failure mileage was 127,000.

2020 Hyundai Kona wirh 22,000 miles, original owner, great condition(except oil usage). First consumption test used 3/4 qt. in 1,000 miles. Seems convenient that Hyundai says 1 qt & the dealership came up with 3/4 so there is no problem. BULL! No oil light came on to warn of low oil.

The contact owns a 2020 Hyundai Kona. The contact stated that the vehicle was consuming an excessive amount of engine oil. The contact stated there was a pinging sound inside the vehicle. There were no warning lights illuminated. The vehicle was taken to the local dealer for a multi-point inspection, and it was confirmed that the oil level was extremely low. The contact stated that an oil consumption test was performed. The vehicle had consumed ¾ quarts of oil in a month. The vehicle was not diagnosed or repaired. The manufacturer was contacted and referred the contact to seek legal assistance. The approximate failure mileage was 22,000.

Car has extreme oil consumption and power stalls which are related to a recall in 2021 for bad poston rings which werent properly heat protected. I brought in and they said it was checked for recall but engine was never actually replaced. My warning lights come on for oil when this happens. My engine could either seize or I could lose power on highway. Car dealership laughed in my face when brought and told me id have to fork over 10k for a new engine which doesn't seem accurate considering Hyundai manufactured this vehicle with bad piston rings.

Vehicle showed these warning lights while stalling out at stop signs: FCA, ESC, and DBC. She was able to turn off the car and restart it. We took it to a Hyundai dealership and ran a diagnostic test where they found nothing wrong. They noticed her oil was low, so they topped it off. This was on a Monday. By Saturday, she had this issue again where she stalled out at a stoplight in the center lane of a 4 lane busy road and had to coast to a parking lot where she restarted the car. We then personally checked the oil again, she was almost out of oil!! We added more full synthetic oil. We googled the issue and saw other 2020 Kona's have this issue. I spoke with Hyundai Consumer Affairs to get advice but they said without any open recalls or extended warraties they couldn't help. They suggested the lengthy process of a repeated oil consumption test at the dealership. We are now taking it to an engine shop today (8-29-25) where he will try to put a syntheic blend in after taking out the full syntheic out. The mechanic said sometimes this helps the oil consumption. We will see how the car runs with the blend. He mentioned that his research shows older models had this issue and Hyundai replaced some engines.

The air conditioning system has a drain for condensation. If it gets plugged up, from debris, algae, etc., it accumulates and sprays it into the passenger cabin. In my auto it sprays considerable water onto the floor boards of both the driver side and passenger side. I encountered such spraying onto my right foot making it slip off the accelerator pad while turning left. While turning right it sprays onto the passenger side. This is an actual spray of water. The dealer reports this is an owner maintenance item. This is not addressed in owner manuals. A search of google issues shows this to be a very big issue. To issues exists. Water onto the accelerator and the brake pedal are safety issues. Wet carpeting causes mold. It is a very bad design.

The engine on my 2020 Hyundai Kona failed suddenly while driving, causing complete loss of power. There were no warning lights until after the failure. The vehicle was towed to a Hyundai dealership. Initially, the dealership stated the failure was related to an open recall from 2021 and warned that repairs might not be covered because the recall had not been completed. I sent them a written request outlining both NHTSA Recall 21V-301 (federally mandated) and Service Campaign 974, asking for documentation supporting their diagnosis and any communications with corporate. This request was ignored. Afterward, the dealership said they would replace the engine, but upon completion they recommended replacing certain bolts and hoses at my expense ($849), claiming that if I declined, any future related repairs would not be covered. When asked why these parts were not included in the repair or how their condition would void future coverage, I was told they were “normal wear” items not covered under warranty. No documentation or policy basis was provided. When asked whether the repair was processed under Recall 21V-301 or Campaign 974, they stated it was not tied to either and was filed under the powertrain warranty without corporate involvement. Multiple shop personnel had earlier confirmed verbally that the failed part matched the recall defect, but the service manager provided a different explanation and refused supporting documents. The dealership also claimed Recall 21V-301 was “co

Back up camera had not worked since purchase. It is now August been dealing with the dealership and Hyundai National with a case number and zero help to rectify this issue. It is not my fault the sales man who sold me this car left two days later. anyone I speak to at the dealership, is not there again the next week. even hyundai usa are consistently unable to even get a manger to call me back. This is unacceptable. at this point any warranty is expired, this car was sold with a faulty camera.

I am the original owner of a 2020 Hyundai Kona equipped with the 2.0L Nu MPI engine. This engine has been subject to known manufacturing defects, including excessive oil consumption, timing component wear, and premature failure. Hyundai has acknowledged that my specific engine falls within the range of engines affected by this defect and has confirmed that it is part of a recall/service campaign group. However, Hyundai is refusing to repair or replace the engine because it passed a vibration test back in 2021. That test was performed over three years ago, and my vehicle is now experiencing major engine problems, including the activation of check engine light with code P0017, which refers to crankshaft-camshaft correlation issues — a known symptom of the engine defect. Hyundai is denying coverage based on a test that is now outdated and irrelevant, despite the fact that the engine is part of the known defect group and is showing signs of failure consistent with hundreds of similar cases. The vehicle is no longer under powertrain warranty, but the root cause of the failure is clearly related to the previously identified defect. Hyundai’s refusal to act puts me, and potentially others, at risk of sudden engine failure due to timing or lubrication problems. This is a potential safety issue if the engine stalls while driving. I respectfully request that NHTSA investigate Hyundai’s use of past vibration tests to deny coverage for active and dangerous engine defects. Owners like mys

While driving on the highway, our vehicle suddenly stopped accelerating without warning, forcing us to pull over immediately. There were no warning lamps, messages, or prior symptoms before the failure occurred. We had to stop on a narrow shoulder with no guardrails, leaving us exposed to fast-moving traffic and putting our safety at serious risk. The vehicle was inspected by a local dealership, who diagnosed the issue as a failed fuel injector. This component is available for inspection upon request. The problem has not been reproduced, but the diagnosis has been confirmed by the dealer.

The horn stopped working. I have owned several cars and never had a horn malfunction. This is an important safety feature and is mandated, like airbags. They should work.

I was driving when I heard a rattle below the car. About a mile later, my engine died. Turns out the oil plug fell out causing irreparable damage to my engine. Was fortunate to be able to coast down the bottom side of the bridge I was on to a safe spot off to the side.

Car is losing power. Car is stopping in the middle of the road. Car was towed to my Personal mechanic on June 21,2025 who has ran a diagnostic on vehicle & vehicle is throwing out an Engine Failure Code. Check Engine light is blinking ; car is making odd "knocking type" noises. First appeared June 20, 2025. Car is not safe to drive due to losing power. Vehicle is now being towed to the dealership (after multiple calls) and the loss of power is concerning/dangerous if vehicle looses power with traffic around. I feel I won't be able to get the vehicle and myself off the road safely before an accident/injury/fatality occurs. I will upload a copy of the diagnostic report

Recall 203 was done on vehicle immediately upon purchase in 2021. Recall 974 was done and CNDS software installed in 2022. Engine stalled and check engine light came on at the end of February. Took car in March 11th to the dealership was told that the engine would need to be replaced due to code P1327. Said there was piston noise. Told me none of it is covered and that I would be out of pocket almost $9,000.00 with a car that is 5 years old. Have a case open with Hyundai Consumer Affairs (Case#[XXX]) and have not heard anything back from them. I am needing to know if this should be covered. According to my research it should be.
