The engine was spewing oil into the air filter and also out of a hose near the turbo. It was also consuming high amounts of oil, yes its available for inspection. I was driving on a busy public highway and my car lost power and would not accelerate no the problem has not been confirmed as of yet vehicle has not received official inspection yet there was zero warning lamps, messages, or any indicator of any kind that there was a problem. there still isnt
NHTSA complaint #11757596 — an unverified report by a vehicle owner.
The dash will completely go black except for red words *no signal.* and all warnings are no longer visible, I cannot tell what speed I’m going, or what percentage battery my car is at. I don’t see visible lane or collision warnings. It is very unsafe and I have been to the dealership twice to try and fix it. The issue returned both times.
NHTSA complaint #11752687 — an unverified report by a vehicle owner.
I purchased a 2018 Hyundai Kona, and it has had one major issue after another. It burns an excessive amount of oil, the engine misfires, and now the turbocharger is failing. I’ve already spent approximately $2,300 repairing the air conditioner and engine, and I can’t afford thousands more in repairs.
NHTSA complaint #11751885 — an unverified report by a vehicle owner.
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.
NHTSA complaint #11737318 — an unverified report by a vehicle owner.
On two separate occasions while in drive and accelerating, the car display indicated an “engine has been turned off, move to park” error. The car automatically went into neutral and I lost all control of acceleration until I came to a full stop, put it in park, and turned off the car.
NHTSA complaint #11731640 — an unverified report by a vehicle owner.
The Kona barely wants to accelerate and stalls out while driving. Even though I recently got a oil change there’s oil consumption and the oil is black as if I never got a oil change. I took it to a hyundai dealer ship, i told them what was wrong they said it’s the timing belt. When that’s not the issue. I recently took it to a mechanic to get a third opinion and to see and fix what is wrong. He declined fixing it saying there’s more to it that is wrong and looks like there’s an engine defect and even complained that the oil was so black. I told him that doesn’t make sense because I’ve been getting my oil consistently. He couldn’t fix it. So now I’m stuck with a vehicle that barely drives and stalls out while I’m on the road and it keeps burning more oil. No one knows what is wrong with it.
NHTSA complaint #11730285 — an unverified report by a vehicle owner.
I bought the car in November 2025. I was on a highway, going at a comfortable, 65 mph speed (a few weeks after purchasing this happened the first time ). Suddenly, the car stopped accelerating, of course I panicked, slowly pulled off to the shoulder, and shut the car off. Luckily, it was not rush hour . I restarted the car, and it was normal driving. I texted my salesperson and asked if he had heard about this issue. He said no. No warning lights or messages appeared as that happened. The speed had decreased and stayed at 36 mph for a few seconds. A few weeks later, it happened again, this time it stayed at around 36 mph. I pulled over and shut the car off, restarted, and no issues. This time I told my salesperson I wanted to bring it in, but they had a one-month wait and offered no help, didn't seem phased or concerned. I took the appointment for February 17, which was approximately a 4-week wait. Again, no lights or warning signals. The third time this happened I was merging on to a very busy ramp to enter a busy highway, and the speed stopped at 11 mph, and I panicked, pulled over restarted the car and that was enough for me to call and insist they take the car as soon as possible, as we were expecting a major snowstorm which did happen the next day. I did not take the car out and brought it in to the dealer on Monday. Again, they seemed unconcerned but took the car after I insisted. The car has been there for 2-weeks now and they claim they cannot find a problem. I called Hyundai corporate. After investigating, they too said there was nothing they could do since they could not find a problem. I may add that while this is happening I am stepping on the gas and nothing happens.
NHTSA complaint #11718634 — an unverified report by a vehicle owner.
While the cruise is set, traveling on I44 with no other car in front of my Kona, the adaptive cruise control will start to flash and apply brakes immediately. The speed will drop instantly. Thankfully no other vehicle has been behind me, otherwise it would have caused a massive wreck. I have taken the Kona to the shop 5 to 6 times for this situation, but they will not do anything since they can not duplicate it. I took a video recording of it happening, and they still would not do anything. The first incident was December 31, 2024. This happens every other week when I travel out of town for my daughter parenting time with her dad.
NHTSA complaint #11718329 — an unverified report by a vehicle owner.
While stopped our 2019 Kona EV at a traffic light with my foot on the brake, the car spontaneously accelerated and crashed into the car also sitting at the light about eight feet in front of us. If there wasn't a car in front of us, we would have gone through a busy intersection at very high speed. The front end of the car was destroyed and both airbags deployed. The car was towed to a collision center and is considered: "Totaled" . We tried to get it inspected for the computer system to confirm what happened, but there was no interest by any party. There was no pre-warning or issues with the vehicle before this happened. The incident happened about ten miles from our house, and we had been driving it for about 15 minutes. The temperature outside was extremely cold at about 5 degrees Fahrenheit.
NHTSA complaint #11718156 — an unverified report by a vehicle owner.
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.
NHTSA complaint #11707833 — an unverified report by a vehicle owner.
The timing system was repaired in February 2025. After similar symptoms of vehicle stalling, the check engine light came on Found a software update that needed to be completed to determine if engine needed replaced. Dealership has refused for seven weeks to complete the entire job of the update which includes running a diagnostic of codes. Instead, they have been arguing that the timing system needs replaced and not providing the codes from the safety software update. Obviously there's a much deeper issue if the timing system keeps breaking down.
NHTSA complaint #11699021 — an unverified report by a vehicle owner.
The cruise control operation is unusual and the speed can vary greatly while it's engaged in moderately hilly terrain (not extreme) on the interstate ([XXX] through Kentucky and Tennessee). With the cruise set at interstate speeds and starting to climb a hill, the speed can drop by as much as 6mph below set point as the cruise control very, very slowly starts to increase throttle to compensate for the grade. Eventually it will stop the deceleration at that up to 6mph speed below the set point, before slowly starting to accelerate back up to the set point. One instance I timed was 22 seconds between the speed first falling below the set point, down to 6mph below, before recovering back to the set point. Sometimes it overshoots the set point by 2mph, meaning it could cause you to exceed the speed limit and/or your intended driving speed if the uphill is long enough for the speed to fully recover itself. It is not an issue with vehicle power available as I can easily maintain an exact speed through the same hills using the throttle manually without cruise control, it is only an issue with how the cruise control is programmed or executed. An 8mph variance with cruise control on the interstate in non-extreme terrain is a safety concern because it makes the vehicle unpredictable by other drivers who are trying to time their maneuvers around trucks and other vehicles and when my car suddenly slows significantly next to them they have to suddenly change or abort their maneuvers. It has not been reviewed or inspected by anyone else. It is a rental vehicle and not available for inspection by request from me, but may be from the owner. There were no warning lights or any other indication there was a problem recognized by the vehicle. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
NHTSA complaint #11689044 — an unverified report by a vehicle owner.
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.

The button that sets or changes the speed control broke and no longer provided functionality, requiring replacing the whole right-side steering wheel button control module. This in turn required removing the entire steering wheel, which included removng the driver’s side airbag.

my Kona sputters when I put it in gear EVERY TIME. I have purchased gas at several stations so getting bad gas in the tank cannot be an issue. I’ve also had to replace the coil packs twice within 6 months. December 2024 and July 2025

This has happened 3 times and I’ve only owned the car since Sept 2023, the first time was Feb 4 2024, then Feb 28th and March 11, 2024, when I am trying to accelerate I push on the gas and the rpm’s will go higher but the car doesn’t gain any speed.so when trying to pass a vehicle I can’t because it will do this and it’s dangerous, I do have a video of this
