Consumer Description

January 28, 2026 The vehicle has stopped in the middle Of the street with sign «loss of power, check your battery» or something like that and after few attempts to turn it off and on it went to Accessory mode. After 15-20 minutes it completely died. So unsafe with kids in the car during extreme cold temperatures. Free Hyundai road assistance- quoted me 3 hours or so, i had to pay for towing elsewhere. No doubts its iccu, since tow truck driver attempted to jump start and from dead it went to accessory mode and died again almost instantly. I read on the Facebook about iccu problem of Hyundai, if this is engineering defect it should be remedied.
