The Hyundai Kona is one of the easiest SUVs to drive. Even novice drivers would have no problem driving it. Keep reading this post and discover what you need to know about this beautiful car.

How reliable is the Hyundai Kona?

The 2022 Hyundai Kona has an impressive reliability score of 82 out of 100. JD Power has given the Kona a reliability score of 91 out of 100, making it one of the best. This score confirms what we already knew about the reliability of Korean cars.

With its standard engine, the Kona offers an EPA rating of 30 MPG in the city and 35 MPG on the highway. These are excellent marks for a subcompact SUV. Add in the fact that the new Kona comes with four-wheel drive, and you’ll agree it’s a family SUV.

Common faults of the Hyundai Kona

The Hyundai Kona is an excellent car, it also has very good reliability; However, like any other car it also has its problems. Next we will take a look at 7 common Hyundai Kona faults that you can encounter:

1. Engine problems

The first part most Kona drivers complain about is the engine. According to one of the owners, his engine died three times while he was driving the Kona.

Another driver said the problem started as soon as the “ check engine light ” started to show. Wasting no time, the driver took the car to a local dealership, where technicians diagnosed the engine and said the driver needed to consider replacing the battery.

Car Complaints registered 145 complaints about the 2019 Kona. While the NHTSA in the United States received 145 complaints and one recall. Many drivers reported abnormal knocking noises coming from the engine. At some point, NHTSA had to remove the Kona’s engine. So Hyundai had to recall nearly 160,000 models of the 2.0-liter Nu MPI-powered Hyundai Kona.

If you leave the faulty engine unattended, your Kona will consume excess oil. Sometimes there will be a knocking noise that will cause the engine to stall or even seize up. If the Kona’s engine dies at the wrong time, it could put you and other drivers in danger.

Another risk is that the engine can cause the connecting rod to pinch through the engine block. If you do not act quickly, an oil leak may occur, causing a fire in the vehicle.

Unfortunately, Hyundai cannot replace the engines fast enough. So car owners have to wait. As a result, a couple of Hyundai owners decided to seek legal representation to process the claims. According to drivers, Hyundai takes too long to repair or replace the engine .


Experts suspect that the leak from the Kona’s piston oil rings is the main cause of engine failure. This complaint was confirmed by some drivers who filed complaints with the NHTSA.

Possible solution

We recommend that you take your Hyundai Kona to your nearest Hyundai dealer. In 2021, Hyundai notified vehicle owners about this issue.

The automaker asked drivers to go to their nearest Hyundai dealership. Once they get there, the technicians will overhaul the engine and update the engine control software.

2. Failures with the airbags

Another possible problem with the Hyundai Kona is that of the airbags. Drivers reported various problems with the airbags, saying they could not deploy. According to a driver, the Kona’s airbag failed to deploy during a collision. Additionally, the Kona’s automatic brakes failed and the cruise control continued to attempt to steer the vehicle despite the collision warning.

At the same time, another driver said the Kona hit a traffic light pole, went uphill and flipped over before coming to a stop. In this case, the airbags deployed.

Another driver revealed in Edmunds that he was in a tragic accident. As a result, the car was totaled. According to this driver, the Kona was struck from the front and rear, but none of the airbags deployed.


Air bags may not deploy in all accidents . But, in general, they can be deployed in certain types of accidents.

Possible solution

All the airbags in your car must work perfectly. Therefore, we recommend that you take your Kona to your nearest dealer.

3. Problems with the electrical system

Drivers also complain about the Hyundai Kona’s electrical system. The owners of the car have registered more than 59 complaints about this problem. The 2018, 2019, 2020, and 2022 models seem to share this problem.

A driver of the 2022 Kona said the problem with the electrical system started with the Kona dying at stoplights. And there were no warning lights on this. After several tries, the Kona started, but the throttle didn’t work. Then the pressure warning light came on. When the driver took the car in for diagnosis, nothing was found wrong with the vehicle. Then the Carplay could not stay connected or does not connect at all.

Another driver reported that the blind spot monitor on the right side of the Kona lit up and beeped at random times. Even when there was nothing in the blind spot itself.

One more owner said that while driving with the cruise control set to 45 mph, the Kona sped to 53 mph. The headlights seem to have a problem, too. Sometimes they don’t work as needed.


Several factors contribute to this problem. For example, when the car’s battery no longer allows driving, the electrical system often stops working because the battery is not powering the vehicle.

Possible solutions

Take your Hyundai Kona to an auto electrician to have it looked at. Also, make sure you only use quality batteries. If you use low-quality batteries, your Kona may have problems with its electrical system.

4. Fault with transmission

The Hyundai Kona also has transmission issues. A driver in Edmunds said the 2020 Hyundai Kona began having powertrain problems within weeks of purchasing it.

After hearing rattling sounds from the rear, the driver decided to speed up, but the Kona screeched. The driver brought the Kona in for inspection, but the technicians were unable to find any issues.

When this article was published, Hyundai had not released any information regarding the powertrain. Some of the Hyundai Kona transmission faults include shift delays and a gear that sticks occasionally.


One of the main causes of this problem is a lack of transmission fluid. You want to make sure you replace the fluid every 30,000 to 60,000 miles.

Possible solutions

Always make sure to only use transmission fluid recommended by Hyundai. Also, perform maintenance on your car at regular intervals.

5. Collision Avoidance System (FCA) Malfunction

Drivers also complain about the Hyundai Kona’s forward collision avoidance system, which tends to malfunction. Sometimes the Kona fails to warn drivers of an impending collision. Often the frontal collision system is activated unnecessarily .

According to one owner, the 2020 Kona SE makes a “ ding ” sound , and then a large message appears on the control panel that says “Check Forward Collision Sensor.” Soon after, the Kona will apply the brakes. Then it will shut down and you will have to reboot. According to this driver, when this happens it will feel like a collision.

According to Hyundai, when the FCA is not working properly, the FCA warning light should illuminate. However, car owners say that the FCA stopped working without sending a warning message.


This problem can be traced back to the Kona’s battery. If the Kona’s battery is low, it is likely causing some safety features to malfunction.

Possible solution

Always keep the battery fully recharged . Replace only the old battery with the new one. Thankfully, Hyundai has made some improvements with the new 2022 Kona. It comes with an excellent Forward Collision Avoidance Assist with Pedestrian Detection.

The FCA system is not designed for certain stationary objects such as trees and poles. Hyundai insists that the system is a driver assistance system and is not a substitute for safe driving. Therefore, drivers still need to exercise caution when driving on the highway.

6. Low gas mileage and battery problems

Other Hyundai Kona owners complain about low gas mileage. Usually the Kona will have bad gas mileage after the driver turns on the air conditioning. It is difficult to confirm whether the cause is an air conditioning or engine failure.

There are also cases where drivers have to start their Kona. But only the battery problem has left some stranded on the roadsides.


A faulty transmission and a bad engine are responsible for low mileage.

Possible solution

We recommend taking your Kona to the nearest mechanic to resolve this issue. Hyundai released the 2022 Hyundai Kona N Line, which has an impressive EPA rating of 29 city and 35 MPG highway.

Although, actual mileage varies with driving options, road and weather conditions, driving habits, and the condition of the 2022 Hyundai Kona.

7. Oil combustion faults

Another drawback that drivers seem to complain about is oil burning. One of the drivers had to change his oil three times in less than 7,300 miles. But Hyundai recommends changing the oil between 3,000 and 5,000 miles. Due to the problem of burning oil, drivers find it difficult to speed up on highways. The Kona can sometimes stall while driving at low speeds .

Hyundai is facing a lawsuit from drivers who allege that the Hyundai Kona forces them to check oil levels frequently. Drivers also say that driving a Kona forces them to add more oil to the engine than the owner’s manual recommends. Adding too much oil cannot be a solution as it can submerge the crankshaft, add the drivers.


Experts suspect that the engine problem is responsible for the unusual reduction in engine lubrication. Immersion of the crankshaft and damage to the gaskets and seals could be another cause.

Possible solution

To remedy this problem, Hyundai recommends drivers check the Kona’s oil levels at 1,000-mile intervals. Take your Hyundai Kona to the nearest dealer. The technicians will diagnose the cause and give you a solution.


Should you buy a Hyundai Kona? Of course. The Hyundai Kona is one of the most affordable cars on the market. Now there’s also the Kona EV (an all-electric version) that boasts a robust design and nimble performance. The Kona is not only fuel efficient, but it comes with a host of features that will make commuting from home to work a breeze.

We recommend that you avoid the older models of the Hyundai Kona, as you are likely to buy them with problems. Preferably buy your Hyundai Kona new and take good care of it. So that the Kona is always in good condition, you should try to do a review. Lastly, use only motor oil and battery that are recommended by the dealer.
