Hyundai Kona Electric

"It had a dead cell, so none of the electronics in the care worked, so we couldn't start it or go anywhere. Hyundai towed the car in at their expense, replaced the battery, and we got our car back."

"First happened March 16. 12 volt battery did not have a charge and would not start the car. Had to get a AAA jump. Took it to the dealer. They said the battery was good and put it on their charger for 45 minutes. Told me to drive it more so the 12 volt battery could charge when the motor was driving the car. Car worked fine until April 10. Came out in the morning. Car would not start. Measured battery at 4.5 volts. Put it on my own old charger and charged it to 12.5 volts. Next day all good. Drove the car 40 miles. At night battery was 12.75 volts. Next morning battery was dead at 4.8 volts. Car would not start. Used my old charger to get it started and drove it to the dealer. They've had it for a week now and have told me that they think something is drawing power when it shouldn't but they don't know what. Also they wondered if I'm using an app of some sort with my phone to connect to the car. I am not. I plan to go to the dealer tomorrow morning to get an in-person report and try to get a loaner until the problem is fixed."

"Failure of 12V battery caused car to suddenly slow down to dangerous speed, requiring towing to dealership"

"Had to get the rotors resurfaced due to rust that accumulated as a result of using the maximum level of regenerative braking."

"Road noise in the vehicle, in my opinion, is excessive and main reason I would not buy again."
