Vehicle started to stall at low rpms. While idling at red lights, engine would stall and go into limp mode. All safety features, such as forward collision would stop working. Car would need to be turned off and restarted for a temporary fix. No engine lights would come on. Car inspected by dealership and cannot figure out what the cause is. VIN comes up saying that my car is not part of the recall.

The contact owns a 2019 Hyundai Kona. The contact stated that while his daughter was driving 45 mph, the check engine warning light illuminated, and the vehicle shut off. The driver pulled over to the side of the road and the vehicle was towed to an independent mechanic to be diagnosed. The mechanic related the failure to NHTSA campaign number: 21v301000 (engine); however, the vehicle was towed to a dealer and the dealer declined to honor the recall repair due to sludge in the oil cap. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 100,220.

The car's engine stuttered after pressing on gas pedal when engine is cold. When pressing on gas pedal from idle position at stop sign, engine does not switch from 1st -> 2nd gear.

Vehicle safety complaint narrative on Saturday, December 6, 2025, I brought my 2019 Hyundai Kona to millennium Hyundai in hempstead, new york, the dealership where the vehicle was purchased, for evaluation due to engine safety concerns. While driving the vehicle, we heard a knocking sound coming from the engine. One week earlier, on November 29, 2025, we brought the vehicle to our local mechanic after noticing the noise. The mechanic advised that the engine oil level was low and refilled the oil. Despite this, the knocking sound continued. Due to ongoing concerns about potential engine failure and because the vehicle is still under warranty, we scheduled an appointment with millennium Hyundai for further diagnosis. The knocking noise raised serious safety concerns. On December 6th, we contacted the service manager, who advised us that the pistons were bad and they would need to replace the engine. On Monday, December 8th, we called the dealer and they then told us, that before any work could be done, that we would have to do an oil change for $90, drive the car for 1,000 miles and come back for an oil consumption test for $600 before they could make the repairs under the warranty. We are submitting this complaint to report a potential safety defect related to engine performance and reliability in the 2019 Hyundai Kona, as unexpected engine failure could pose a significant safety risk and, their requirement that we have to drive an unsafe car for 1,000 miles could be dangerous to the driver, passengers, and others on the roadway.

Prior to 100,000 miles, I noted knocking in the engine, especially while going uphill. The knocking would appear and disappear, possibly with oil change intervals. No check engine light ever appeared. After 100,000 miles, the engine progressively began knocking, losing power, and eventually stalling on the road occasionally. I have had to put on my hazards and restart my car. One time, I was barely able to pull over to the side. Again, no check engine light ever appeared. I have several videos of the vehicle in motion with audible knocking, and almost stalling. The videos show the dashboard with no check engine light appearing. There was no sign of oil loss. No smoke. No oil stains under the vehicle. I was due for an oil change when the knocking and stalling became severe. I visited the dealer and informed them of the engine issues. They performed an oil change. And then could not reproduce the problem I experienced. Told me to come back if it happened again. This sounded odd to me given the severity of the knocking and stalling. Or it signaled to me that an oil change including refilling the oil solved the issue. Long story short. An oil consumption test was performed. The engine is consuming oil. I am scheduled for combustion chamber cleaning per the technical service bulletin, as mentioned by the service rep. I am not confident that this will fix the problem. Given that this is the same / similar engine as the recalled 2018-2021 Kona for the same / similar issue. Oil consumption.

I believe that I’m leaking oil somewhere and that it’s due to the recall with the piston oil rings that’s on my car.

The contact owns a 2019 Hyundai Kona. The contact stated that while driving at an undisclosed speed, there was a knocking sound coming from the vehicle with the check engine warning light illuminated. The vehicle was driven to an independent mechanic, where it was diagnosed with engine failure. The contact referenced NHTSA campaign number: 21v301000 (engine); however, the VIN was not under recall. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 94,634.

Over the last 2 1/2 months the car has shut off approximately 5 times while driving, without warning. Most instances have been while pulling into a parking lot, but one time (so far) it shut off while trying to back into my driveway. I'm fearful it will happen while on the freeway. I took it to the dealer, but there wasn't a fault code so they refused to look at it unless I left the car with them to drive, and wanted to charge me $45/day for a rental so I could get back & forth to work until it happened again while they were driving it.

The contact owns a 2019 Hyundai Kona. The contact stated that while operating the vehicle, the check engine warning light illuminated, with a knocking sound coming from the engine compartment. The contact stated that the vehicle shutoff while idling. The vehicle was taken to the local mechanic who was unable to determine the cause of the failure. Later, while idling at a stoplight, the vehicle stalled and failed to restart. The vehicle was eventually towed to the local dealer, who confirmed that the connecting rods had failed and punctured a hole in the engine. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure, and 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 94,000.

I have gotten a oil change over a month ago and my car is still running low on oil. Sometimes my car would shut off while I’m driving on the road with cars behind me. I have gotten my car oil topped off three different times since getting my oil change. It also makes a fan like noise as well. There’s no leak at all. It’s very bizarre.

The component that failed was the connecting engine rod bearing. The engine is currently in the vehicle located at a Hyundai dealership. The connecting engine rod bearing failure came after 1 or 2 engine miss-fires. The vehicle suffered poor performance, I was unable to start the car and properly accelerate the vehicle. The vehicle has exhibited poor acceleration/ jerk acceleration since purchase. However, this incident occurred immediately during initial startup in a parked position. The vehicle rode roughly upon initial observance of this engine miss fire which led us to deem the engine and car unsafe to use. The vehicle was initially towed to an independent service center where they identified the engine missfire code. The vehicle was then towed to our frequently used independent servicer where they said the problem related to low compression in the engine possibly something internal in the engine. Next we towed the vehicle to our preferred Hyundai dealership. Hyundai confirmed the engine missfires and connecting rod bearing failure. A claim is in process with Hyundai to assess the vehicle further. The check engine light came on when the engine miss-fired initially. An earlier check engine light came on for a missfire earlier in the 2025 and earlier in 2022 and in 2023 which led to a catalytic converter replacement. While not certain, we think that low compression and poor engine performance has plagued the vehicle since purchase. The vehicle drive jerky(poor/delayed acceleration when pressing the gas) and had early catalytic converter issues prior to 50k miles.

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.

My Kona n line is not functioning well. Especially after driving for a longer period of time. About 60% of the time, upon letting go of my brake, the car jerks. Going from 0 - 5 mph is the worst. The car definitely hesitates many times. Again, it is when I have driven it for over 10 minutes. I took the car to a service department in el monte, CA on 11/1. They cannot find the problem. They rode with me and it did not show at that time. They released the car to me. The Kona n has a recall but not my car, the Kona n line. The recall is for the same problem. I am extremely frustrated. I have another appointment on Tuesday of this week to take to the glendora service department. I don't know what to do. I am not one to complain but this is not safe. This is my fifth Hyundai. Nothing but good cars until now. Please advise. [xxx] [xxx] . Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The contact owns a 2021 Hyundai Kona. The contact stated that while attempting to accelerate from a stop and while driving at various speeds, the vehicle stalled unexpectedly. The vehicle was coasted to the side of the road, and the vehicle was turned off and restarted, and continued driving. The check engine warning light was illuminated. The vehicle was taken to auto zone, where it was determined that the spark plugs had failed and needed to be replaced. The spark plugs were replaced; however, the check engine warning light remained illuminated, and the vehicle stalled. The failure had occurred three times; however, the last time, the vehicle failed to restart, and there was smoke coming from underneath the hood. The vehicle was towed to the dealer to be diagnosed. The contact was informed that the turbocharger and the piston rings had failed, and the engine needed to be replaced. The vehicle was not repaired. The vehicle was towed back to the residence. The contact became aware of NHTSA campaign number: 21v301000 (engine); however, the VIN was not included. The manufacturer was not informed of the failure. The failure mileage was 121,334.

I am having issues with my oil consumption and my car is going through a quart of oil every 1-1. 5 weeks. There have been similar recalls on the 2019 Kona’s which have the same 1. 6l 4-cylinder engine. My car is currently a little over 126,000 miles.

My vehicle turns off while driving, which has almost cost mine and my child's life twice on the highway and once inside a roundabout. It often happens after acceleration and slight braking soon after, rpm goes to zero and a few dash lights come on. I am completely unable to accelerate, have to coast to a full stop until I can brake and put it into park and then push to start again. I'm sure you can see how absolutely life threatening this situation is when it happens in moving traffic! I have replaced spark plugs, ignition coils, all fuel injectors, camshaft sensor. The mechanic cannot get it to replicate the problem when he has it as it does not happen every time but I see that this is a common problem with Hyundai. After all above repairs, this problem persists and I have no direction as to how to remedy this, but driving this vehicle now has me completely anxiety ridden and terrified for my life.

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.

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.

Engine light was on - I was told by belmont enterprise on sept 17th to keep driving the vehicle even though it needed repairs immediately.

The piston went through the top of my engine with my entire family in the car. We managed to get to a mechanic. And bring it to the dealership. We are very lucky to be alive.

The contact’s daughter owns a 2018 Hyundai Kona. While the contact’s daughter was driving approximately 65 - 70 mph, the vehicle started decelerating and sputtering before the vehicle coasted to the side of the road and stalled. The check engine warning light was illuminated. The vehicle was towed to a certified mechanic, who diagnosed the vehicle and determined that the engine needed to be replaced. The vehicle was not repaired. The dealer was contacted and confirmed that the VIN was not under recall. The manufacturer was informed and opened a case. The manufacturer referred the contact to the NHTSA hotline to report the failure. The failure mileage was approximately 100,000.

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.

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 contact owns a 2021 Hyundai Kona. The contact stated that while coming to a stop, the vehicle stalled. There was no warning light illuminated. The vehicle was able to restart. The vehicle was taken to the dealer and was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 86,000. The VIN was not available.

About a month after purchasing my car it shut down on the highway while driving. It completely lost power so I could not accelerate or even press the brake. Only the emergency brake stopped me from going into other cars. I started the car up again and then it worked fine until about another month later it happened again. I was on an exit ramp on the highway and it lost power. Cars had to quickly go around me as I had no control of my vehicle. Neither brakes or gas pedal worked at the time and my check engine light stayed on. I then took my car to Hyundai service where they told me my car went through 2 quarts of oil in one month. They want me to drive this car another 1,000 miles knowing it’s dangerous, unsafe, a risk to me and other drivers and a fire hazard to have an engine consuming this much oil. I fear to drive this unpredictable car any more. The manager of Hyundai knows it’s unfair but must follow protocol. I just don’t understand how they can tell someone to drive a stalling car waiting for an accident to happen.

I own a 2019 Hyundai Kona with around 110,000 miles. The vehicle has been consuming an excessive amount of engine oil, approximately one quart every 1,000 miles. I first noticed the issue around 80,000 miles when oil levels began dropping significantly between oil changes. The problem has worsened over time, and during a long family road trip, I had to add a total of about 8 quarts of oil just to keep the engine from running dry. I took the vehicle to a Hyundai dealership for an official oil consumption test, which confirmed the loss rate (1 quart per 1,000 miles). However, Hyundai motor America stated that this level of oil consumption is "within factory specifications" and denied any repair or assistance. This seems unreasonably high for a modern engine and creates both a safety concern (risk of running low on oil during travel) and a financial burden (frequent oil top-offs between changes). I am concerned this may indicate a defect similar to oil consumption issues seen in other Hyundai and kia engines.

Piston ring failure. No oil in car and no leaks. P0301 code and knocking sound. Unable to drive.

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 engine burns too much oil. I have to put it a quart every 2 weeks.

The contact owns a 2021 Hyundai Kona. The contact stated that while driving at slow speeds in stop-and-go traffic, the vehicle inadvertently lost motive power. The contact was able to restart the vehicle but almost immediately lost motive power. No warning lights were illuminated. The vehicle was towed to an independent mechanic, who diagnosed a failure with the piston oil rings, resulting in damage to the engine. The contact was informed that the engine needed to be replaced. After investigating the failure, the contact related the failure to NHTSA campaign number: 21v301000 (engine); but the VIN was not included. The manufacturer was not notified of the failure. The failure mileage was 96,000.

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. The vehicle does not feel safe at pulls to the right , I have problems with my ac as well as my transmission is slipping. The car loses power when I accelerate. I believe was sold a lemon car I purchased from carmax.

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. These repeated mistakes have caused significant inconv information redacted pursuant to the freedom of informat.

The piston oil ring recall. I have had a mechanic determine I am having the exact same problem as the recalls but my VIN is not covered. Please update the recall so my repairs can be covered.
