2021 Hyundai Kona Electric

Check regenerative brake warning comes on and the emergency brake applies while driving also when I come to a stop. When I started my car the immediately the light came on. When I cut my car off the light clears. It happens when I’m braking. The regenerative brake light warning is becoming more frequent. I took my car back to the Hyundai dealership and they “checked” it out and found no problem with my vehicle. They ran a diagnostics and a update for my car, but 4 days later the warning can on again, after the repair.

Sunroof exploded. On 19 January 2022 around 15:45 (Pacific Time) while driving approximately 65mph in my 2021 Hyundai Kona Electric on Hwy 60 (Moreno Valley, California), west-bound I experienced a loud explosion sound in my Kona and glass raining down on me and the inside of the car. I looked up and noticed there was a hole in the sunroof (see attached photos). I immediately found a safe place to exit the highway and stopped.

The contact owns a 2021 Hyundai Kona Electric. The contact stated that while his wife disconnected the charger, the vehicle caught fire without warning. There were no reported injuries. The installation plug was melted. The vehicle was taken to the local dealer where it was diagnosed the connection wiring needed to be replaced. The vehicle was not repaired. An inspector was able to inspect the vehicle. The manufacturer was notified however no further assistance was provided. The approximate failure mileage was 8,000.

After charging the vehicle at home with level 2 charger to 100% it would not go into drive or reverse. It can go to neutral or Park only. The car is at the dealership and they told the battery must be replaced when one is available. It is a safety concern because one can get stranded on the road with vehicle that does not move although is fully charged.

On 8/11/21, I tried to start my Hyundai Kona EV, and it displayed the high voltage warning . The car would not start or go into gear and had to be towed to the dealership. We purchased the car in May 2021, and it had about 3000 miles on it at the time. At the dealership, the mechanic diagnosed it as a faulty battery and indicated that the whole LG battery underneath for the electric car would need to be replaced. After doing further research, there is already a recall on the 2018 to 2020 models for the same issue, with the battery catching fire in some instances. The car has the same battery a the 2018 to 2020 models. The guidance for those model years has been to park the car outside, in case there is a fire. We live in an HOA condo (and do have the option to park outside our garage). As of today, there is no ETA of a fix for a new battery. If they end up replacing it with another LG battery with the same faulty cell issues, I feel like this is a danger to my and my family's lives. Due to the battery issue, they also quit selling the Kona in Korea in April, a full month before we purchased our car. They sold us a car with a known issue. I want them to buy back this car, due to the safety issues.
