“I have a 2021 Hyundai Kona Electric Vehicle with approximately 20,000 miles. On August 26, 2022 several warning lights came on indicating that the lithium battery was inoperable but fully charged in danger of catching fire. The dealer immediately towed my vehicle and disconnected the battery. The recall for battery replacement due to fire risk for the 2018-2020 now appears to be affecting the 2021 model year. The dealer is telling me they have no replacement batteries and cannot give me a timeline for replacing mine nor can they assure me that will resolve the problem. …”

“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.”

“The car was unable to charge using level 3 DC fast chargers, necessitating the use of a level 2 charger for an extended length of time in order to be able to return home. A Hyundai dealer replaced the charging inlet lock actuator (invoice attached).”
