Engine And Engine Cooling Problems of Hyundai Kona - part 1

The contact owns a 2019 Hyundai Kona. The contact stated that the vehicle had experienced excessive oil consumption. The contact stated that while driving 70 mph on the highway, the vehicle stalled. The contact was unable to pull over to the side of the road. The contact was able to restart the vehicle and continued driving. The contact stated that the failure recurred while driving into a parking lot. The battery warning light illuminated on several occasions. Additionally, the contact stated that the check engine and low oil pressure warning lights were intermittently illuminated. The vehicle was taken to auto zone and to an independent mechanic, where it was diagnosed and determined that the piston oil ring failure had caused low oil pressure, which resulted in the timing failure. The failure was related to NHTSA campaign number: 21v301000 (engine). The dealer and the manufacturer were notified of the failure but denied a loaner vehicle or towing assistance to the dealer located 75 miles away. The vehicle was not repaired. The failure mileage was approximately 113,000.

I am writing to express my frustration and concern regarding my 2021 Hyundai Kona, which currently has only 88,754 miles. My vehicle has been experiencing excessive oil consumption along with an ongoing check engine light. The diagnostic trouble codes are p0017 and p0011. In an effort to resolve the issue, I have had both the intake and exhaust vvt components replaced and the oil changed. When the problem persisted, my mechanic advised that Hyundai oem parts were required. I then spent approximately $700 replacing the components with oem parts, yet the check engine light remains on and the same issues continue. At fewer than 89,000 miles, I do not believe these are problems that should be occurring on a properly maintained vehicle. I have already invested significant money trying to repair what appears to be a larger issue, and I am left with a vehicle that is still not functioning correctly. I am requesting that Hyundai investigate this matter and provide assistance in diagnosing and repairing the underlying cause. Given the known concerns regarding excessive oil consumption and timing-related issues reported by other Hyundai owners, I believe this situation warrants Hyundai's attention and consideration for goodwill assistance. I would appreciate a prompt response outlining what steps Hyundai is willing to take to help resolve this issue. I have been a Hyundai owner in good faith, and I am disappointed that after spending hundreds of dollars on recommended repairs, my vehicle remains unresolved.

Vehicle (2019 Kona) is subject to recall 203 (piston ring/bore defect). On xxx puente hills Hyundai refused the mandatory physcial inspection, instead attempting to charge $1,100 for 'leak repairs. ' an independent inspection by valvoline on xxx confirmed the engine is dry with no leaks, proving the dealer's claim was fraudulent. Following a recent ecu update, the vehicle triggered a p0420 code—a known symptom of the internal engine damage covered by recall 203. My Hyundai corporate case (#xxx) is currently stalled as the dealer refuses to provide technician notes or perform the safety inspection. I am operating an unsafe vehicle with documented internal mechanical failure. Requesting immediate intervention for a physical cylinder inspection. Please refer to the attached document (summary of events) for the full chronology, supporting evidence, and email correspondence related to the dealership's refusal to perform recall 203. See attached pdf (evidence_email_correspondence) for documentation of the dealership's refusal to provide technician notes and their unprofessional communication regarding this safety recall. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My 2019 Hyundai Kona has been burning oil, I’ve done great upkeep on it, including topping the oil off in between services. This is because it obviously has been burning oil, well recently it started stalling, then starting/turning it over has been acting up. The rpm’s have not been stable at all an I’ve ran two diagnostic test on it, they came back as a “camshaft error” I can’t remember the exact code at the moment. However the mechanics I have questioned said it’s probably from the oil pressure being messed up from the oil burning up. Whether it be the sensor not regulating properly or the engine itself not getting enough lubricant. I have heard from others with Hyundais an it’s not just Kona’s, people are saying they burn through their oil fairly quickly compared to other cars they’ve had. With that being said, the car now stalls in traffic and the check engine light came on finally, that’s when we first ran diagnostics. Which I have had diagnostics ran at one place I go to for oil changes, a one at a meineke, and soon to be a third at autozone because I need to get the exact code again. I’m worried because my mom an I have been sharing this vehicle and the stalling makes it dangerous, it can be put in neutral and restarted but I have a service appointment with a dealership to see what they can do, however I feel this is happening from something caused straight from the manufacturer, not improper care or overuse. So I’m filing a complaint because if you stall while crossing traffic and could not restart, or know how to restart it, you could get in a wreck. This all seemed to start happening as well right after the vehicle rolled over 100,000 miles, go figure right? an if you needed to inspect this happening it would not be hard to do, all you would have to do is turn over the engine, then drive it for a bit an it will eventually stall, an you could also see the rpm’s bouncing and the noises it makes.

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.

Power train the engine roars up and drops jarring you back and forth second car within a yr first blew up brand new both and hyundia and dealership blew me off.

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.

96,247 mi engine knock and complete oil loss within 3,000 miles of last oil change symptoms consistent with NHTSA recall 21v301 (Hyundai recall 203) and warranty extension txxm coverage.

The contact owns a 2019 Hyundai Kona. The contact stated while driving the vehicle at an undisclosed speed, he noticed he had an engine knock, and noticed that the engine was consuming a good amount of oil with no warning lights or oil leaks. The contact pulled over to the side when the knock started and noticed the vehicle was starving of oil although a recent oil change shows it was recent. The vehicle was taken to a dealer where it was diagnosed to have poor service, and engine sludge although dealer stated there was none. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 120,132.

Vehicle frequently and quietly stalls while driving in active traffic, creating an immediate safety hazard. Vehicle is a 2019 Kona with the 2. 0l nu mpi engine, which is the exact subject of NHTSA safety recall 21v301 (recall 209). Hyundai motor America (case #42541672) is actively refusing to honor or inspect the vehicle under the safety recall mandates, claiming a lack of dealership service history overrides a federal safety defect.

Engine blew a head gasket so had to have the engine rebuilt @ a cost of $13,000. Car only had 22,500 miles on it. I think that should instigate a recall.

Last week just driving to school, my engine started to knock. So the next day we take it to a local mechanic shop and it exploded while they were test driving it and they diagnosed it with rod bearing failure. So I contact Hyundai and get it towed to the Hyundai dealership for them to inspect it and eventually do an engine swap, but after it got dropped off I was told it’d be $360 to get it diagnosed and filed and they said that I have no warranty. I explained to the rep that the class action lawsuit regarding the theta 2 gdi engines extends the warranty to 15 years/150,000 miles for all subsequent owners especially since I’ve had the ksds installed. They’re refusing to cover damages even though my car was affected by a manufacturing issue on their end and was part of major recall campaigns. My car failed at 94,000 miles while up to date on services and the representative was recommending I ask Hyundai for “good-will funding” but I don’t need their “good will” I need them to make the situation right and cover all my expenses related to my blown engine.

The vehicle suddenly stalled while driving on the highway at normal speed without warning. The engine lost power completely, creating a dangerous situation and a risk of collision with surrounding traffic. The vehicle had to be towed to a repair shop, where the issue was diagnosed as engine failure. There were no warning lights or prior symptoms before the incident. This appears to be a serious safety-related defect. I am aware that similar engine issues have been reported in Hyundai vehicles.

My 2019 Hyundai Kona is equipped with a 2. 0l nu mpi engine covered under recall 203 (NHTSA campaign 21v301) for defective piston oil rings. The recall inspection was performed and closed at a Hyundai dealership in September 2023. The engine was passed and not replaced. Following that recall closure, the vehicle has required the same repair four times: replacement of the cvvt assembly-exhaust, camshaft assembly-exhaust, and timing chain tensioner. Each repair was performed under warranty. The recurring diagnostic code is p0017 (crankshaft/camshaft position correlation - exhaust). Total warranty expenditure on these repeated repairs exceeds $7,800. During one of these visits (January 2025), the technician noted the cvvt had a "slight hold on rotation" and flagged possible exhaust camshaft damage. The vehicle has also experienced stalling while driving, creating a direct safety risk to the driver and others on the road. An independent repair facility has evaluated the vehicle and provided a written assessment concluding that full engine replacement is required, and that an underlying engine defect is causing the repeated component failures. It is my position that the recall 203 inspection was performed inadequately — the defect was present at the time of inspection and was not identified. The recall remedy did not resolve the condition it was designed to address. Hyundai has since declined to replace the engine despite the documented failure pattern and independent shop recommendation. The vehicle is available for inspection. The problem has been confirmed by both a Hyundai dealer and an independent shop.

The contact owns a 2021 Hyundai Kona. The contact stated that while driving at an undisclosed speed, the vehicle lost motive power. The contact was unaware of the warning lights that were illuminated during the failure. The vehicle was unable to be restarted. The vehicle was towed to an independent mechanic, where it was diagnosed and determined that the piston rings had failed and that the engine needed to be replaced. The vehicle was not repaired. The vehicle was towed to the dealer, where it was diagnosed that the piston rings had failed and that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure, and a case was opened. The approximate failure mileage was 82,000.

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

Engine is consuming oil and developed piston slap, per the mechanic I took it to. Currently it sounds like there is gravel inside the engine and it does not seem safe to drive. The malfunction indicator lamp has also come on, the codes were cleared by my mechanic but they told me it likely will return. The piston slap developed a week ago today (Thursday), the mil started flashing 3 days later (Sunday), mechanic did the oil change on Tuesday and noted the piston slap at that time. All symptoms point to the issues noted in #21v-301, but my VIN is not included in that recall per the NHTSA website.

Low speed hesitancy and shuddering. Car has lost power when driving at 55 mph. Car does not want to move at very slow speeds as in a parking garage. It hesitates and starts to roll backwards.

The contact owns a 2019 Hyundai Kona. The contact stated that while driving on several occasions at various speeds, the awd warning light illuminated and was reset each time the vehicle was restarted. The contact also stated that over a couple of months, while downshifting, stopping, or decelerating, the vehicle stalled on several occasions. Additionally, the contact stated that while driving at approximately 30 mph, the check engine warning light illuminated. The vehicle was then taken to an autozone, where a handheld diagnostic machine retrieved diagnostic trouble codes: p0017 (crankshaft) and p0171 (system too lean), and it was observed that the oil reservoir was empty. Two quarts of oil were added to the vehicle. The contact stated that after being serviced, the vehicle was idling high and stalled while driving at unknown speeds on several occasions. The vehicle was taken to a dealer, where it was diagnosed with a sheared timing pin, and it was determined that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 100,000.

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.

Vehicle struggling to accelerate and rolling back when brake is not being used. It stays at a few miles per hour even with full pressure on the gas pedal. A mechanic reviewed and stated the problem was due to low compression in the engine, causing the pistons to misfire. This issue has happened a total of 5 times and has almost caused other vehicles to crash into me due to sudden loss of speed and not being able to accelerate fast enough to properly get to safety.

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 has 82. 000 miles on it, and the engine started to rattle as I entered the street to my house, and the motor quit running. I had the vehicle hauled to a repair garage for analysis, and they said the piston rings failed. The vehicle is in perfect shape except for the broken engine.

My 2020 Hyundai Kona (VIN: km8k62aa3lu561277) 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 I-5 near the leucadia 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 encinitas. 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 #42349744) 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 22-01-042h requires only the vibration inspection; engine replacement is authorized if "no pass" – no separate oil consumption test or monitored drive.

The check engine light came on while driving. Vehicle was assessed by mechanic with strange diagnostic code; full oil and filter change done. Check engine light still on and engine stalled while driving on freeway. Took to dealer and was advised the car requires cvvts (which is essentially a new engine), serpentine belt and spark plugs (approx $3600). There is a known engine defect with the 2018 Hyundai but they refuse to do as a recall and refuse discounted repair on a vehicle that 8 years old with 92,000 miles. This vehicle is owned by my young adult child and I believe it is undriveable since stalling at full speed is quite dangerous.

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.

VIN: [xxx] 2021 Hyundai Kona experienced sudden engine failure at approximately 103,000 miles. The engine began knocking without any prior warning, and the check engine light came on at the same time the knocking started. The vehicle was not driven for an extended period after the issue began. There were no earlier warning indicators or drivability issues that would suggest neglect or lack of maintenance. The failure was immediate and unexpected. This vehicle had previously received Hyundai recall t8y, which involved an ecu update related to engine monitoring and performance. Despite this manufacturer intervention, the engine still experienced sudden failure. Hyundai has denied warranty and goodwill coverage for this failure. This appears to be a premature engine failure and raises concerns about reliability and safety due to the sudden nature of the issue. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The contact owns a 2018 Hyundai koa. The contact stated that while the daughter was driving the vehicle began to sputter and jerk before stalling. During the failure the oil warning light flashed off and on. The vehicle was towed to the local dealer who diagnosed that the engine had failed due to carbon buildup. The contact was advised that the engine needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure but no assistance was offered. The contact was informed that the VIN was not included in the NHTSA campaign number: 21v301000(engine) the contact indicated that the vehicle had experienced that same failure listed in the recall. The failure mileage was 90,000.

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.

Was driving when the car seemed to lose power and would not accelerate and started shaking. Check engine light came on and got it read, the code indicated a misfire and other errors. There was no one local to fix it as we were out of town. So we replaced the plugs that were indicated and noticed how badly damaged they were. Vehicle started to drive better before stalling out again and replacing the rest of the plugs. Was able to get it home and seemed to be driving normally but then we noticed it has an oil leak now. We have to keep a religious check on the oil because of the amount leaking and the fact the car isn't giving us a low oil warning. We took it to the dealership and they said we needed a new engine and it was just outside the power train warranty. All of this occurred our 78,000-80,000 mile mark. The dealer would not even change the oil before of how bad the leak was. This car was for our teenage daughter and its not safe for anyone to drive. I believe the dealership knew this car had issues, we bought it pre-owned and have only had it 6 months.

The cars engine vibrates when accelerating and hesitates. It is always dangerous to stall after hitting the gas. This issue causes many near accidents. It began to vibrate at less than 70k. It has 90k now. These engines have had issues and mine is no exception. They should recall this engine as it's dangerous. Top of the line and poop.

The contact owns a 2019 Hyundai Kona. The contact stated that while driving at an undisclosed speed, there was a burning odor coming from the vehicle, with the low engine oil warning light illuminated. The contact stated that while checking the dipstick, the contact became aware that the engine oil level was low. The dealer was contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 150,000.

Known problem of oil consumption . 1 week used 3 quarts . Wife driving down road oil light. Engine light seconds later engine seized at 55mph. Lucky to drift off road.
