2022 Hyundai Kona

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.

In January 2026, my engine light illuminated and the vehicle lost power. The dealership found a sudden loss of compression across all four cylinders, requiring a total engine replacement. This occurred without warning, only two months after a routine oil change at the same facility where no issues were reported. Despite opening a case with Hyundai corporate, there has been no progress. My research indicates that while NHTSA Recall 21V301 (Safety Recall 203) specifies 2019–2021 models, the 2022 model shares the same engine design and identical reports of stalling and compression loss. My vehicle has been at the dealership for three months with no resolution. The dealership says they are running tests requested by tech line without providing documentation of the tests or the results. Although, the initial test performed indicated that it was a compression ring issue.

The vehicle displayed a warning lamp indicating a Cooling System Performance failure. The specific defect relates to the Integrated Thermal-Management Module (ITM) and the thermostat opening prematurely, corresponding to Diagnostic Trouble Code (DTC) P218100. This issue requires a repair outlined in Technical Service Bulletin 25-EM-007H, involving a spring installation and ECU update. This failure creates a serious safety concern because improper thermal management can cause the engine to overheat or force the vehicle into a reduced-power 'limp mode' without warning. A sudden loss of acceleration or engine stall while driving in traffic significantly increases the risk of a crash.

December 2025: Yet ANOTHER horn failure. Pressed the vehicle's horn to alert another driver that they were drifting into my lane on the highway, and it FAILED to produce the loud sound that it is SUPPOSED TO make. It needed to be replaced again for the FOURTH time. Part 96611-J9500 was replaced—AGAIN. This is a continued safety issue that Hyundai has neglected to address and fix. Spontaneous horn failure is a HAZARD. The horn is there to warn others of possible danger.

Hyundai has multiple complaints regarding Horn malfunction in the Hyundai Kona. I went to use my horn today to prevent an accident and found my horn does not work. I have checked my fuses and relays and neither are blown leading to the horn to be unable for use

I had the radiator replaced by the Ourisman Hyundai Laurel dealership on 10/1/25. Radiator replacement was under warranty. On 10/4/25car overheated while driving. I pulled the car over and called for a tow truck. Car was leaking lots of coolant. Brought it to service center at Ourisman Hyundai Laurel, they stated “the hose to the thermostat was not all the way on. Put hose on correctly no more leaking.” On 10/15/25 multiple lights came on the dashboard including the master warning light. Took car to Ourisman Hyundai Laurel again; received the car back, dealership stated “ TECH COULD NOT DUPLICATE THE LIGHTS POPPING ON DASHBOARD. UPON FURTHER DIAGNOSIS TECH FOUND THAT THERE WAS A CONNECTOR NOT GETTING THE PROPER CONTACT TO COIL NUMBER 1 TECH RECONNECTED THE CONNECTOR AND TEST DROVE THE VEHICLE FOR 5 MILES. NO CONCERNS PRESENT AT THIS TIME.” On 10/20 I brought the car in to Ourisman Hyundai Laurel again because Electronic Stability Control light as well as ABS warning light and several other warning lights came on multiple times. Ourisman Hyundai Laurel service technician said they could not duplicate the problem and there is nothing they can do. This is a safety issue because it concerns the electronic stability control and brakes.

The horn on my 2022 Hyundai Kona has failed multiple times. It has been replaced twice already, and it has stopped working again at around 65,000 miles. This is a serious safety concern as I am unable to alert other drivers in emergency situations. The repeated failure of the horn suggests a possible defect in the electrical system or horn assembly. I am requesting an investigation into this issue.

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 INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

When I first brought the car for its first service appointment (6 months after purchase), I informed the service dept at the dealership that the car seemed to accelerate itself when I was driving. They said they hit a reset button and that I shouldn't have any more problems. What I found was that the car then drove sluggishly but it did not accelerate anymore. Recently however (2.5 years into the purchase), the car started "sliding" when I hit the break pad. I took the car in again for service a few months ahead of time and they said that my car mat was wedged under the break pad and that was what was causing the car to slide when I hit the break. The car slid but also accelerated by about 5 miles, however I was able to quickly break and stop it without incident. This last service was on Friday, August 1st, and on Sunday August 3, the car slid and accelerated again - without the floor mat being wedged under the break. On Monday morning (August 4th) I called Hyundai so many times that I lost count. I was never able to speak with a service employee but I was given an appointment for a week and half later. According to ChatGPT, it is a common issue with the 2022 Kona and it should be recalled.

Horn was going in and out of working for the first few months after purchase. Now the horn does not work at all. It is not the fuse. As seeing through other complaints this is a very common problem and should be on Hyundai to fix.

For the second time in 6months, the horn has stopped working. Coastal Hyundai in Melbourne FL replaced the first horn on 1/14/2025. On [XXX], the horn has stopped working again. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My horn on my car has went out the first time and now it just went out again and it’s a manufacturing issue! Hyundai refuses to fix it because it’s not under warranty anymore! And it’s so dangerous now since I don’t have a horn again! I should have not have to fix it when it’s not my fault! And other people have the same issue with your Kona’s to! The dealership even told me that’s it’s been an issue with the horns!

The contact owns a 2022 Hyundai Kona. The contact stated while driving at an undisclosed speed, the vehicle lost motive power with the check engine warning light illuminated. The vehicle was able to be restarted. The vehicle was taken to the dealer but was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 80,000.

The horn is not working. On forums for this specific car it is a common problem for this make and model. This means I cannot alert other cars or pedestrians

Radiator is failing between 60k and 70k miles with no check engine lights. Leaking an entire reservoir of coolant within a 24hr time period. Even when the temperature gage went above the middle mark and to the 3/4 mark the check engine light never came on.

I believe it’s a barring in the engine but it is like a knocking.

I have had my horn replaced three separate times at my local Hyundai dealership. It recently passed the NC vehicle inspection, but the horn failed the third time sometime after that inspection in Feb-2025. I have never had a horn EVER fail on ANY car I have owned for the past 50 years. A horn is a critical safety necessity and it is expected to work - especially in times of emergency. I was almost run off the highway, once by a semi-trailer and each time I discovered my horn had failed - it was due to my needing to use it to alert pedestrians or other motor vehicles to avoid accidents. The dealer would not reveal WHY this has failed three times except to state that they 'replaced the horn'. The dealer is the only one to have attempted an examination, diagnosis and supposed repair for this problem. There are no warning lights or other type of notification that would let me know of a horn failure. The only way to know that it had failed - was my immediate need to employ the use of the horn in an emergency - and it's silence aka malfunction at the worst possible times.

While accelerating onto the highway, the engine backfired and suddenly lost speed, violently shaking.

On February 3rd 2025, directly after putting my Kona in park, I felt it pulsing, saw the RPM dial bouncing repeatedly up and down, and the overhead lights flickering in rhythm with the vibrating/pulsing and RPM dial bounces. I recorded this incident, then turned my car off and on again at which point these observations could not be repeated - in other words, the car was acting fine. There were no other observable issues until March 1st, 2025, when these exact symptoms emerged under different circumstances. I came to an idle at a red light (with the auto-start/stop feature turned off for this drive) when the RPM bouncing, car pulsing back and forth, and lights flickering happened again. My car felt as though it was about to stall this time until, thankfully, the light turned green and I could accelerate. The issues dissipated with acceleration. I have this incident on video as well. I have a little over 63K miles on this car. I drive all day for my job, so it's used often for short trips throughout the city.
