The vehicle has been inspected and repaired multiple times by an authorized Hyundai dealership and remains available for inspection upon request. -The engine shut down unexpectedly while driving at highway speed, resulting in loss of power and the need to coast and pull over. This created a risk of rear-end collision and loss of control in traffic. Subsequent failures left the vehicle unable to start, creating risk of stranding in unsafe locations. -Yes. The authorized Hyundai dealership confirmed engine-related and crankshaft-related issues and performed repairs on multiple occasions. Despite these repairs, the problem has recurred. -The vehicle has been inspected and repaired multiple times by an authorized Hyundai dealership. -Yes.

VEHICLE SPEED CONTROL, SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
After a routine service visit, the vehicle’s braking and speed‑control systems began to behave abnormally. The ABS/ESC control module was replaced or reprogrammed without documentation, and immediately afterward the vehicle’s braking feel, speed‑control behavior, and forward‑collision warning timing changed noticeably. These changes created a safety risk because the vehicle no longer responded in a predictable way compared to its original performance. The affected components are available for inspection upon request. The issue was reproduced multiple times under normal driving conditions. Braking response became inconsistent, and the speed‑control system no longer behaved as it did before the service. The timing and behavior of forward‑collision alerts also changed compared to pre‑service operation. These changes created unpredictability in traffic, especially during following‑distance adjustments, stop‑and‑go situations, and sudden‑braking scenarios. The dealership did not provide technical documentation or explanation for the module replacement or configuration changes and did not acknowledge the change in system behavior. The manufacturer’s customer service reviewed the case but did not provide technical findings. An independent service center could not verify the original configuration because the manufacturer did not provide the Manufacturer Build Sheet. The vehicle has not been inspected by police or insurance representatives. No warning lamps or dashboard messages appeared before or after the issue. The only indication of a problem was the sudden change in braking, speed‑control, and forward‑collision system behavior immediately after the service visit.

About 2 weeks ago I tried to start my car and the dash board starting flickering and glitch. Roadside assistance said all I needed was a battery. I got a battery and everything seemed fine until today. My car is starting to do the same thing. When I looked up recalls my VIN doesnt match for a recall I think my car should be under. The Battery Charge Sysytem is failing I believe. I have videos.

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.

While slowing down from highway speed during hot weather, the front passenger door suddenly became unlatched and partially opened. A warning alert sounded, and I had to pull the door closed. There were no prior warnings or symptoms, and the dealer has not been able to reproduce the issue.

ENGINE, FUEL/PROPULSION SYSTEM, POWER TRAIN
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)

I’ve been having issues that align with the Safety Recall 239 to repair a condition involving the Electric Power Control Unit ("EPCU"). I seem to be having by a coolant leak, my car is overheating, has stalled and has struggled to start. I started noticing something wasn’t right a couple of weeks ago but wasn’t sure what until more “symptoms” have occurred since and I found the recall information. My air conditioner also will stop blowing cool air when the over heating happens. No lights have come on my dash board alerting me of anything needing to be serviced.

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.

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.

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.

POWER TRAIN, SERVICE BRAKES, STRUCTURE:BODY
Body: The hood/Under the hood: There is a wide ½“ or more gap on the right and left side of the hood. I can see inside under the hood from a distance. It is not flush while connecting to the rest of the vehicle. I can see the ground after opening the hood. The engine and all the components are exposed to the elements. This is a new vehicle from the dealership brand. There is no cover for the bottom to protect the engine or protection for wirings and other mechanisms under the hood. Winters in Illinois is brutal and floods. Poor acceleration and Brakes Restriction while steering experienced dragging sounds and forced pushing and pulling. I do not trust the steering wheel mechanism at all and have to grip it to make sure I keep complete control of the steering wheel and fearful of the reliability of the breaks because I have experience being pulled or pushed while merging and having to panicky while using the brakes. I must press extremely hard to brake in slow traffic and use extreme hard brake to slow to a complete stop during rush hours. Fuel performance is horrible. This model requires gasoline. When I feel my vehicle up with fuel the tank is a fuel guzzler. The fuel disappears in days. I must refill the tank once a week. This car does not have good mileage. Doors All the doors automatically unlock when put in park. Fuel performance is horrible. This model requires gasoline. When I feel my vehicle up with fuel the tank is a fuel guzzler. The fuel disappears in days. I must refill the tank once a week. This car does not have good mileage. The steering mechanism is terrorizing my driving experience. Merging and changing lanes while driving in traffic I experience resistance and restriction. Inside the front panel Inside the car appears to have glitches such as the temperature settings flipping from inside/outside air. The radio shuts down. Window fluid splatters the entire windshield obstructing view. Purchased 2025
