Hyundai’s electric car “Kona Electric”, which is quite popular in the world, but when more than 10 fires occurred in two years and the controversy escalated, Hyundai Motor Company recalled it. However, the recall process is chatty among consumers and the battery is only replaced when abnormal signs are detected after the BMS update. Borrowers say this is difficult to see as an adequate measure and recently filed a class action lawsuit against Hyundai Motor Company.

As the Kona Electric chain fire recall continues, this time an accident has occurred due to a brake jam and the controversy is on the rise. If a brake defect is recognized and a recall is made, the image of the electric vehicle will be significantly affected. Today’s AutoPost Issue Plus takes a step closer to Kona Electric brake lock.

Brake blocked
A rollover accident has occurred
On the 13th of last month, Mr. A, who lives in Miryang, Gyeongnam, had a serious accident while driving the Hyundai Kona Electric. On the way down near the house, the brakes suddenly stopped working, making it impossible to stop.

Mr. A tried pressing the accelerator pedal and the brake pedal several times to see if he had pressed the wrong pedal, and even though he tried to press the brake pedal all the way down, it was useless. During that time, the speed reached 150 km / h and Mr. A, who repeatedly ran in fear for 30 seconds, was forced to stop by hitting the car against the right axle wall. At the time of the accident, the car had only been bought for 6 months, and was on the verge of being scrapped because it rolled several tens of meters after rollover, and Mr. A was taken to hospital with a serious injury in which they had broken five ribs to his right.

Brake blocked
this is not the first time
The brake jam was not just caused by Mr. A, who had an accident this time. Mr. B suffered a brake jam in July, six days after the Kona electric car was released. Mr B said: “I applied the brakes because the distance from the car in front of me was close, but I went in without feeling any pressure.” Fortunately, the car in front left avoided a serious accident and I was later told that the electronic brake module had broken by putting it in the service center. Subsequently, the car was refunded.

In May, while driving the Kona Electric to work, Mr. C nearly had an accident with the car in front of him due to a brake jam. Fortunately I was traveling slowly and was able to avoid the accident by slowing down naturally. Mr. C said: “Even though I pressed the brake hard, there was no reaction, so I was embarrassed.”

In electric and hybrid cars
A total of 19 cases occurred.
The cause is the electronic brake
According to the Korea Automobile Safety Research Institute, there was no problem with the internal combustion engine model between Kona and the problem only occurred in hybrid and electric vehicle models. The total number of reports of Kona brake defects received by the 11th of this month was 19. In 2018, when the Kona electric car was first launched, there were no related reports and 4 cases were received in 2019 and 15 cases this year.

Electric and hybrid models have an electronic brake system, which is very likely to have a problem. The system is a product developed by Hyundai Mobis and is installed on Nexo and Soul boosters as well as Kona electric and hybrid vehicles.

Experts mentioned two possible causes of the electronic brake jam phenomenon. The first is the possibility that the electric hydraulic brake booster, present only in the electronic brake, is faulty.

When you press the pedal, it appears that a “ sponge phenomenon ” has occurred where air is mixed in the hydraulic cylinder and the hydraulic pressure is not being transmitted properly.If there is a problem with the hydraulic booster, this problem may occur. The hydraulic brake booster is a device that amplifies the power of the brake pedal with the power of the electric motor and the increased hydraulic pressure through the brake booster is transmitted to the brake pads to stop the wheel.

The second is the possibility that there is a problem with the electrical signal itself. The mechanical brakes used in the internal combustion engine models are physically interlocked, so if you push the pedal all the way down, even if insufficient, braking force is generated and deceleration is possible.

However, in the case of an electronic brake, if the flow of electrical energy that activates the brake is interrupted somewhere, such as a broken wire or an error in the electronic control software, the brake will not work at all as it does in this case.

Hyundai Motors analyzes EDR
“No brake steps have been recorded”
Currently in their own investigation
Mr. A, who recently suffered a rollover accident, entrusted the analysis of the traffic accident recorder (EDR) to Hyundai Motor Company, but was informed of the investigation results by Hyundai Motors, saying, “There is no brake track and Excel only “. This is a situation that can lead to consumer negligence.

In response, an expert explained: “It is possible that there is a problem with the brake signal switch on the pedal.” A Hyundai Motors official explained: “We are currently conducting a self-investigation and if the cause is identified, we will act accordingly.”

Korean Automotive Safety Research Institute
A technical analysis survey launched
Meanwhile, the Korea Automobile Safety Research Institute, an automobile defect investigation agency of the Ministry of Land, Infrastructure and Transportation, has been conducting a technical analysis investigation to determine the possibility of defects since July. An official said: “This is an investigation which judges that there is a particularity or tendency to suspect a defect.”

Technical analysis surveys are conducted when consumers report defects in vehicles or when manufacturers perform free repairs. If it is determined that there may be a security-related incident later, a recall action is taken.

Solving problems with the lemon method
The Ministry of Land, Infrastructure and Transport has been fired.
In June, a Kona Electric borrower complaining of a malfunctioning brake applied for an arbitration decision on an exchange or refund through the Lemon Law from the Ministry of Land, Infrastructure and Transportation, as symptoms were not resolved after repairs following. The Limone Law is a system that allows consumers to change or refund if the problem recurs even after receiving a new car and repairing it three times for general defects and two times for major defects within one year.

The brake problem corresponds to a serious defect and, despite several repairs, the Ministry of Land, Infrastructure and Transport rejected it. It seems that another example of the reputation of the lemon method will remain.

Accident
The reaction of netizens
Not long after the recall of Kona Electric, brake problems appeared and netizens responded in horror. There are “I can’t even get in the car because I’m scared”, “Was the test done correctly?”, “The Kona is scarier than the Corona”, and “If the brake breaks when I drive, it’s terrible to think about it.”

Furthermore, there have been many reactions that have pinpointed Hyundai Motor’s response. “EDR says you didn’t hit the brake, but is it the driver’s fault?”, “Hyundai is unconditionally the driver’s fault”, “If we look at what we’ve done so far, this won’t work properly”, “From the arbitration law’s dismissal lemon “I’m going” and “I’m sure the US is already preparing for a recall”.

From Hyundai’s point of view
I have encountered some great bad news
Next year, Hyundai Motor Company plans to release Ioniq 5, Kia Motors CV and Genesis G80 EV. These are more advanced than the previously released electric cars and are important models that will mark the large-scale opening of the electric car era.

But before that, Kona Electric’s subsequent shortcomings, which are popular around the world, are very bad for Hyundai. This is because reliability can significantly decrease in both the domestic and global markets due to safety concerns. If the perception that “Hyundai electric vehicles are not safe” is already spreading, it is inevitable to reach the sales volume of electric vehicles. It was Auto Post Issue Plus.
