“Hyundai is failing to provide the interim remedy promised in your safety recall report 21v-127 (attached). This remedy consists of simply disclosing the safe charging limit percentage for the propulsion battery. The recall report states, under remedy program, owners will also be provided with instructions to manually lower the battery's state of charge limit via the infotainment system. I requested that information from Hyundai customer care. However they replied currently there is no remedy available. …”

“Hyundai issued a several recalls that notified me of various updates related to my car battery as well as that I cannot park my car in my garage as battery could catch fire. I have taken my car to a local dealer each time for these software updates as required. They originally did a fix for the battery issue back in 2020 but clearly the issue has not been remedied since it first came to light in 3/2019. …”

“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. …”

“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. …”

“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. …”
