2020 Hyundai Kona Electric

While driving approximately 70 mph on I-10 in Louisiana late at night, my 2020 Hyundai Kona EV displayed a “Check EV System” warning while I was on the highway. There were no safe areas or emergency shoulders available to pull over, so I continued driving toward the nearest exit. Approximately 15 minutes after the warning appeared, as I attempted to exit the highway, the vehicle suddenly lost power and rapidly slowed. The vehicle came to a complete stop and could not accelerate, move forward, or reverse. This created a serious safety risk because the vehicle lost propulsion while traveling at highway speed. The vehicle had approximately 62,000 miles at the time of the incident. The vehicle was towed to Giles Hyundai where the dealership diagnosed an internal temperature sensor and resolver failure. Because these components are integrated into the drive system, the dealership replaced the entire traction motor assembly. The repair cost was approximately $9,000. The sudden loss of propulsion at highway speed created a dangerous situation for both the driver and surrounding traffic.

6/17/2024 12 volt battery was dead; EV was fully charged 6/16/2024 using Level 2 charger in my home garage. AAA charged the battery; I drove to Crossroads Hyundai Loveland, CO and asked to have the converter to the main battery checked; this was not done. Crossroads checked the battery via CADEX with "good battery charge" as result. No other diagnostic work was performed. 8/26/2024 12 volt battery again depleted; AAA charged twice 11:06 am (recharge and retest ) and 3:51pm (Bad & replace). I drove again to Crossroads Hyundai which claimed battery test showed good battery. Technician found a draw dropped after pulling fuses F6 multi media and F16 memory. Techline at Hyundai was contacted and tech was instructed to install junction box for fuses (91950-K4061 Junction Box assembly I/PNL 91). The car was undriveable on the Crossroads lot until part received and replaced 9/20/2024. 9/24/2024 when I arrived to pick up the car, the service advisor told me the door was left ajar after car wash, causing draw on battery; the battery was damaged by continued discharge due to strain from parts replaced. Hyundai agreed to replace the battery at no charge to customer. There were no warming lamps, messages or other symptoms of the problem prior to 6/17/2024. My safety, as a senior and woman is at risk if the car was stranded in a parking lot or other area outside of my home garage.

We just had our 2020 Kona updated from the dealer with major software and recall updates. Since that point the car has been draining from the 12volt battery on it's own and killing the charging circuit for the battery. It has caused us to have to jump start the car and not be able to keep the 12 volt charged which runs all of the environmentals and car systems. Unless you have a jump pack with you, you have to jump it after every stop. I have tested the battery and it is fine but the system needs a high end initial draw and is not getting it. I have contacted the dealer but they are saying it is not their problem. This needs government address, as it is the same issue in the NHTSA recalls or Hybrid and EV Sonata and Ioniq 5 models.
