What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2019 Hyundai Kona Electric, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
Component Failed: Electric transmission/drive unit failed twice before 150,000 miles. Still in vehicle, available for inspection. Safety Risk: Loss of propulsion while driving creates risk of being rear-ended or stranded in dangerous traffic conditions. Right now the car is not drivable Confirmed By: Problem confirmed by Hyundai dealership/service center on both failures. Inspection: Inspected by authorized Hyundai service center; manufacturer was notified. Warning Symptoms: Before the failure there was a screeching sound coming from the hood. In both failures, these warnings appeared shortly before or during the loss of propulsion.
The Charging unit made by Enel X called a JuiceBox 40 failed to complete a charge. Upon examination of the charger it was determined that the plug from the unit to the 240V receptacle was fused to the outlet and could not be removed. When my electrician opened the box he was able to force the plug out of the outlet. He found that the plug was burned as well as the copper wire that went to the plug from the electrical box.
Fuel system
Reports naming fuel storage or delivery — tanks, pumps, lines, injectors and fuel leaks.
From owner reports, verbatim
The vehicle began making a clicking/ticking sound under acceleration and deceleration. The noise progressively worsened until The dealer diagnosed the motor as failing internally and replaced it under warranty. Several people online in forums have experienced the same issue, some cases resulted in the reduction gear catastrophically failing causing the vehicle to suddenly stop accelerating. I worry that this issue may result in more sudden drivetrain failures because of how widespread the problem is. Hyundai does not seem to have a definite solution as the noise comes back for many owners.
There has been a battery recall on our Kona EV since March 2021. We were asked to keep the battery charged only to 80% to prevent problems. Hyundai is aware that we need a battery and we were contacted in late summer to set up an appointment to replace it. Every time we try to set something up they tell us that they don't have the battery or the proper parts. This is unacceptable. We have spoken with the service writer several times without resolution. At this point we do not trust Hyundai and are extremely unhappy with our vehicle purchase given the ongoing safety concern of continuing to drive a car with a batter that has been recalled.
Engine
Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components.

I started directing the car to the side of the road to park. As I was guiding the car to a stop, with my foot on the brake, I was about 12 ft. from the car in front of me when the car suddenly accelerated. The vehicle accelerated for approximately 10 ft. before the anti-collision system auto-braked the car just prior to impacting the car in front of me.

Driver assistance
Reports naming forward-collision avoidance, lane keeping, back-over prevention, cruise control and related electronic driver-assistance systems.
From owner reports, verbatim
The contact owned a 2019 Hyundai Kona. The contact stated that while attempting to drive from a complete stop, the vehicle accelerated rapidly through a busy intersection on its own and would not slow or stop, despite the brake pedal being depressed. As a result, the contact briefly lost control of the vehicle as it swerved left to right, only coming to a complete stop after colliding with another vehicle. The air bags did deploy. No warning lights were illuminated. The vehicle was towed to a storage facility and deemed a total loss by the contact's insurance provider. A police report was filed, and injuries were reported. The contact was transported to an area hospital and treated for a broken sternum and hematoma on both her right and left breasts. The manufacturer was not notified of the failure. The failure mileage was 70,000.

Other / unspecified
Reports whose component NHTSA recorded as unknown, or that do not map to one of the categories above.
From owner reports, verbatim
At time of purchase (new) this car did not come with a spare or jack but included a can of fix a flat and a cheep compressor. While traveling I became stranded with an un repairable flat tire and had to have someone come get me with a jack and abandon the car on the side of the road. I then purchased a spare tire kit directly from the purchase point dealer. On a second incident I discovered that the spare tire (donut) does not fit the rear wheels. It does not clear the brake calipers. Come to find out there is no other rim or tire that will fit this car thus leaving the driver with no options should a flat or bent rim happen. Hyundai's solution to this is to throw a can of fix a flat in the trunk. How can that be legal in this country. For the second time in two years.

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.
