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.

I purchased a 2021 Hyundai Kona in 2023. I own it outright. 2 weeks later my engine seized on the CA 118 in the middle lane & I lost steering & power. I don’t know how I made it to the side w cars doing 80. I was shaking. The dealer refurbished my engine no cost , it was due to the oil consumption problem & the piston ring issues many cars in ‘20 & ‘21 had. I had a Hyundai rep call & offer me $400 to sign off on any future engine issues w this car, & I knew this car was likely to have many other future problems after that offer. I did not accept offer. The transmission is also very jerky on surface streets. Well 2 yrs later, the engine started to seize up again today as I was on my way to a dentist appt. I don’t feel safe in this car. I am a 58 y/o woman w fibromyalgia & the stress of the power just shutting down when I’m driving makes my disease flair up terribly. I’ve had many cars & this is the only 1 I’m truly scared to drive alone in , after being stuck on a mountainside road, w no power, no steering, no one w me. I avoid driving at times, because the PTSD from the first incident is always w me . I love to drive - I had a motor home I drove across this country 6 times. I really want to sell this car, but I don’t want some other person to be in danger either. If I knew Hyundais in certain yrs had these issues, I certainly never would have purchased that particular year/model. That should be disclosed w the cars stats if it is known & actually in several class action suits. No advanced warning came on to alert me either - the engine just seized on a mountainside freeway as I was doing 68 mph. I feel lucky to be here after that.

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.

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.

I am reporting a persistent and unresolved excessive oil consumption issue that I began to notice at approximately 61,000 miles. I follow all routine maintenance and oil change schedules, but my car has returned to the dealership I purchased from (only owner), three times for this specific problem. - First Visit (64,074 miles): I shared my observations of excessive oil consumption to the dealership, they stated there was an oil leak at the timing cover and oil pan. They repaired the leaks, however this did not resolve the consumption issue. - Second Visit (65,273 miles) - The oil change done by Mobil at 75,238 miles, before I brought my car in for the third time to Hyundai for the consumption issue, documented that my oil level was at the 'Low'(L) level, this is the case each time I get an oil change around 3,000 miles - The third time bringing my car to Hyundai my mileage was at 78,913, less than 3,000 miles since my last oil change. Before making the appointment my cars engine sounded like it was running rough so we took a look at the oil level, which was at L - The first two times I did the 1000 mile oil test, Hyundai reported that my oil level remained above Full when I returned for a check, shortly after, within an additional 2000 miles, my dipstick would show L. The third reading is TBD.

I am writing to formally escalate a serious safety concern regarding my 2021 Hyundai Kona Ultimate, which was sold to me as a new vehicle in April 2021 but was equipped with tires manufactured in 2019 at the time of delivery. This issue raises significant concerns regarding product safety, quality control, and customer protection. I have already contacted Hyundai Customer Care and have been working with a case manager regarding this matter. During our conversation on February 23, 2026, I was informed that the issue would be investigated and that I would receive an update by February 27, 2026. As of today, I have not received any meaningful response or resolution. The absence of communication and delay in addressing a matter that directly affects the safety of my family is unacceptable. I currently reside in the Boston, Massachusetts area, where winter driving conditions regularly involve snow, ice, and freezing temperatures. Tires are one of the most critical safety components of a vehicle under these conditions. Installing tires that were already approximately two years old at the time the vehicle was sold as new significantly reduced the usable safe life of those tires. According to guidance provided by the tire manufacturer, tires installed on new vehicles should ideally be recently manufactured, and tire age is a key safety consideration regardless of mileage. Because the tires on my Kona were manufactured in 2019, their safe service life has effectively been shortened by several years through no fault of my own.

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.

On February 3, 2026, while driving in a high-traffic turning lane, my Hyundai Kona Electric vehicle suddenly lost propulsion and would not accelerate. The vehicle shut down without warning and could not be restarted. Traffic was building behind me, creating a safety hazard. I felt unsafe due to surrounding vehicles expecting movement, I contacted the police for assistance. The vehicle had to be towed from the roadway. The vehicle was transferred between 3 dealerships before being diagonsed. On February 16, 2026, the issue was diagnosed as a motor position sensor failure affecting the propulsion system. The vehicle has remained inoperable since February 3, 2026, and there is no repair ETA due to parts availability. The vehicle remains at the servicing dealership and is available for inspection upon request. There were no prior warning lamps, dashboard messages, or noticeable symptoms before the sudden loss of propulsion. This incident involved a sudden failure of the vehicle’s propulsion system while operating in active traffic and presented a significant safety concern.

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 Blind Spot Collision Warning (BSCW) light comes on 10 minutes into a drive (we live in a rural area and drive two lane roads for at least 25 miles before multiple lanes). I have had the car in for service on the system twice before learning that this is built into the system. Others are having the same problem, (see the two Hyundai Kona forum links below). I've spent about $600 trying to solve a problem Kona already knows existed (see p. 5-52 of the 2021 Kona owner's manual). Of course I hadn't read the entire manual, but I feel the service technicians should have. I will attempt to put a more detailed description in the files below.

My car consumes a lot of oil. This is a very similar problem as the wrong tempered piston rings. All this car has used is 5W 20 full synthetic oil., which gets changed every 5000 miles. I would burn around 1 quart every 1000 miles. Dealer solution is to put in 5W 30 full synthetic oil. Got a little better but within a few months, back to burning1 quart every 1000 miles. Dealer is now saying Hyundai won’t fix the issue because car now has 116000 miles on it. This has been a problem for a while.

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.

File with NHTSA now please!!!! What do you have to lose??? If anything If they do an investigation we are safe post warranty. Report a Vehicle Safety Problem, Equipment Issue | NHTSA [XXX] The Hyundai Kona Electric Vehicle (EV) has experienced issues with its Integrated Charging Control Unit (ICCU) due to problems with the low-conductivity coolant (BSC-1) used in models produced between 2018 and October 2021. This coolant can crystallize, forming debris that clogs the cooling system, leading to false "Refill Inverter Coolant" warnings and potential overheating risks. A Technical Service Bulletin (TSB 23-01-049H) outlines a recall to flush and replace the coolant with an improved BSC-2 formula to address this issue. However, improper or repeated coolant flushes, if not performed correctly using Hyundai’s specialized equipment and procedures, can leave air bubbles or residual debris in the system, which may impair cooling efficiency and stress critical components like the ICCU, inverter, and electric motor. Repeated coolant flushes, especially when not executed properly, can exacerbate issues by introducing air locks or failing to fully remove crystallized debris, potentially causing damage to the ICCU, inverter, and motor. Air bubbles trapped in the cooling system can reduce heat dissipation, leading to overheating that may degrade the ICCU’s electronics or cause the inverter and motor to operate at unsafe temperatures, risking premature failure. Posts on forums indicate that some vehicles required multiple flushes to clear the warning, with improper flushing sometimes leaving contaminants that continue to trigger sensors or obstruct coolant flow. This underscores the importance of having the procedure done by trained technicians using the correct tools to avoid long-term damage to these sensitive components.

The HVAC drainage system in my 2021 Hyundai Kona failed due to a clogged AC drain line, which led to water leaking into the cabin and mold growth. The dealer reported the drain was blocked by a spiderweb and that moisture had collected under the driver and passenger carpets. They unclogged the line, but did not inspect beneath the carpet or inside the HVAC system. Soon after, I experienced musty odors, asthma flare-ups, and headaches while driving. At-home mold tests under the passenger seat and footwell came back positive. White mold was also visibly growing under the carpet. A similar issue occurred in my fiancé’s Hyundai Elantra, also purchased from the same dealer. His AC drain was clogged and mold tested positive in the cabin, though his car had no smell. Our vehicles are stored in different environments, which rules out external environmental causes and points to a broader design flaw. There are Hyundai forums online confirming this same issue is not isolated to us. Even if spiderwebs were involved, a single web should not disable a critical drainage function and cause health risks. HVAC systems should be designed to resist common environmental factors like debris or insects. I am a cancer survivor (diagnosed in 2024) and must avoid environmental toxins like mold. Despite repeated outreach to Hyundai and the dealer, I was told no inspection or remediation would be provided beyond detailing, which is not sufficient for mold. Component that failed: AC evaporator drain tube Confirmed by dealer: Yes Manufacturer inspection: No – Hyundai declined to investigate Safety concern: Yes – mold has triggered respiratory symptoms and makes the vehicle unsafe for passengers

The last time I got it home it had more issues than when I took it in and wouldn't even catch a charge . (EV) They fried my compassitor trying to fix the inverter coolant recall . I then took had to pay 450 for a diagnostic ' (Kerry hyundai alexandria) They said electric motor is bad and will cost 8000 to 9000. Got a 2nd diagnostic (Jeff wyler hyundai cincinnati) Completely different result- Zero mention of motor ' said Ac compasitor failed. (Had no issues prior to them working on the original recall ) The light for the recall is still on by the way and they want me to pay 3500 for new AC capacitor . (600 diagnostic included in that price ) " The dealership’s failure to properly perform the inverter coolant refill recall directly caused the AC compressor failure in my 2021 Hyundai Kona EV. Before taking the vehicle in for the recall, the AC system was fully functional, delivering cold air without any issues, and the car experienced no charging problems, indicating the battery and cooling systems were operating normally. The recall, intended to flush the inverter cooling system and replace the crystallizing BSC-1 coolant with BSC-2, was not completed correctly, as evidenced by the dealership’s admission that they couldn’t fix it. This botched service likely left air or debris in the cooling system, which, in Kona EVs with a heat pump, could overwork the AC compressor used for battery cooling during charging. The compressor’s failure shortly after the recall service, despite no prior issues, strongly suggests that the improper coolant flush caused undue stress on the compressor, leading to its $3,000 failure, which should be covered under warranty or as a goodwill repair due to the dealership’s error".

My wife's car t-boned another vehicle, but the air bags didn't deploy. Luckily, she wasn't hurt badly, but the vehicle was deemed a total loss, so you can imagine the force of the collision. The forward collision warning and automatic emergency braking didn't activate either. I reported it to Hyundai. They sent an inspector to examine the vehicle, and I also showed them photos and a copy of the police report, but they claim that my car was hit on the side, and the pre collision system doesn't detect imminent side impact. That's completely outrageous. I don't know what their inspector wrote in their report, but the photos and police report are irrefutable proof that my wife had a frontal collision with the side of another vehicle. Hyundai kept denying it because they didn't want to help financially. I attached a copy of their determination letters (the second one was after I submitted a copy of the police report to prove that my wife's car is the one that hit the other vehicle, but Hyundai refused to see it as it happened). This is a link to see the interior and exterior photos of the vehicle: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Crash

There has been a continuous popping noise on the right side of the vehicle near the tire like it’s an axle or something with the suspension. It has been checked and I was told it was normal. The horn will stop working along with the radio and other components in the car. The forward front accident component will say I’ve been in an accident when I have not even been near a vehicle. This has happened on several occasions. I don’t have all specific dates.

My car is a 2021, is only 4 years old and the paint is chipping very fast. I noticed it a few months ago and it is now about 3 inches height, and 1 inch wide. It’s going to continue and paying for a whole new hood when my car is only 4 years old is crazy.

Fill coolant warning came on, we checked the coolant and the coolant level was good. I spoke to a Hyundai service center and the rep said that sometimes this happens with Hyundais and it may go off. Indeed it did but then Fill coolant warning came back and the coolant level was still good. After several weeks of the Fill Coolant warning being on more often than not, the car started one morning but couldn’t be driven as the handbrake was stuck on, the fill coolant warning was on and the tire pressure warning was on, (even though the tire pressure on all tires was ok) I guess this was the EVs way of saying “Do Not Drive Me”. We got the car to the dealership, they performed a scan and found no codes. They preformed a total coolant flush as per Service Campaign T9E. This service was performed on 21 April, 2025 and thus far the fill coolant light has stated off. We bought this car used just 2 months prior and found through previous maintenance history that this EV had this service Campaign T9E done in January 2024. Our concern with this issue is two fold, 1) My wife could have been anywhere when the car went into: Don’t drive me mode. 2) is this going to be an annual event, which will cost several hundred dollars to address each time when this may no longer be covered by warranty

The engine has been a problem since I got the car. It used to just stop in the middle of traffic and just not drive I would have to completely turn the car off and back on in the middle of the highway. I went to Hyundai in Texas to get it fixed and they said they did so I drove it to where I live now In north carolina it broke down again the shaft gear was broken I had to drive it back to Texas for them to fix it the whole way there I was unable to turn the car off while getting gas with the chance of it not Turing back on. got it to Texas and to the dealer they said it was their problem they would fix I got the car back and seemingly thought everything was ok. this past week I was driving to work and all of the sudden on the middle of the right lane of the highway my car just started to slow down and shake a little I had gotten it to the side to pull over and I thought if I turned it off it would turn back on. it turns on but does not drive. I am a [XXX] living [XXX] in North Carolina with a car that has so many problems for it being a 2021 car. with no recall in sight I have seen this specific car on the side of the road more times than I have seen any other car. if someone does not see this as a problem and thinks it shouldn't be recalled you are the issue I need a working car to get to work so I can pay my bills without a car I have no way to make my money this car has been a problem since the get go. Im not asking for a new car I'm asking for this one to be fixed and stay fixed for it to have so many issues is insane and just not safe with the world we live in if my car doesn't start for some reason at any point and something is going wrong its dangerous.

The shark fin antenna came off at 55 mph going down the highway. The dealer who sold me the 2021 Kona SEL, tried to blame us for it, saying there is no way to know if you hit a bird etc. They stated it would cost me about $1,300.00 to repair this. My response was, are you serious? we have had this car for less than 3 months and this is your answer. So i went to a certified Hyundai dealer, both gave the same response, but added our tech is trained to spot defects and said the screws would not be shown, it would have ripped the entire unit from the car if it came off due to a defect. which is entirely untrue. Both dealers added that they had never even heard of this happening before, so they referred me to contact Hyundai corp to open up a registered complaint. The response I got was the dealer was the one who makes the ultimate decision. she gave me a link to buy direct from Hyundai as soon as I stated I would make a complaint here. Then I asked her the same thing I asked both dealers, why are you denying this? This is a very common issue. I also added that if the truck behind us was struck by the antenna ripping off, I would be in court to sue them. I then added it will only be a matter of time before injuries or death from this occurs and that will end up with all of the complaints being used in court to force you to comply. I ended up finding a better deal from a Hyundai dealer than the one she gave me. I performed the repair myself. the repair cost me about 300 dollars. I also want to ad that when i used AI to ask how to tell if the antenna was defective, the explanation and pics were exactly identical to the pictures I took. as this was during warmer months I felt very happy a person on a motorcycle was not hit. People need to research this on their own before purchasing this auto in my opinion.

2021 Hyundai Kona check engine light came on while driving, within 10 minutes oil light and battery light came on and at the same time these lights came on the car stopped working. The engine stalled, leaving the car stuck in the middle of the road. The car turned off, and would not turn back on properly. The car had to be towed to a mechanic where it was discovered that the engine had no oil in it and no longer starts or runs. The car was not yet due for an oil change, there were no oil leaks found, and it seems like the engine burned the oil faster than it should have. The car was functioning properly up until the day of the event, with no issues or warning signs present. There is a recall associated with this model and year relating to engine damage, with the campaign number 21V301000, but there is no recall for this car's VIN. The car stopped driving in the middle of the road which could have easily caused a crash and now the engine needs to be completely replaced.
