From owner reports, verbatim
On April 20, 2026 I was pulling into a parking space. I began to break but something went terribly wrong. My car accelerated on it's own, went over the curb and crashed into a building. Three air bags deployed: two on the drivers side of the car (front and side air bag) and one in the back seat behind the driver (the side air bag). I had a [XXX] in the back seat behind the passenger side of the car in a car seat. I was told at the time of the incident that there was not structural damage to the building that was hit. I have asked my insurance company to inspect the car for any malfunctions but they won't. They deem it totaled and say I am at fault because it's my responsibility to control my car. The police arrived but they did not inspect the car either. I have contacted the dealership (Parkway Hyundai), but they are of no help either. There were not warning lamps, messages or other symptoms of the problem prior to the failure. However, I did notice recently that when I put my foot on the break to start the car that sometimes the break was very stiff and other times it was not. I thought it strange but thought it was just the way my car was. My insurance is Progressive. Claim # XXX INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

Driver assistance
Reports naming forward-collision avoidance, lane keeping, back-over prevention, cruise control and related electronic driver-assistance systems.
From owner reports, verbatim
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.

The contact stated that two other GSA fleet vehicles of the same year, make, and model, as well as a coworker who owns a 2025 Hyundai Konda had experienced the same failure. The contact related the failure to rodents chewing the organic-based fuel lines. The manufacturer was not made aware of the failure. The failure mileage was approximately 900.

Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
Coke spill in cup holders caused a leak to the wiring harness below the center console. It drained the battery, shut down all of the buttons on the steering wheel and shut the infotainment system down. It finally died and had to be towed to Vann York Hyundai in Highpoint NC. They told me that because it was cased by an outside influence it's not covered by the warranty and estimated $800 labor for repair. The leak is a defect.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
