“While charging at a level 2 charger (6 kW) the car stop charging at 61% for no apparent reason. I was unable to restart charging. Within 2-3 minutes of starting the car and driving, received a warning to “check the vehicle electrical system” and then within another minute or two, another warning to “stop vehicle and check power supply.” I was traveling under 20 mph the entire time.”
NHTSA complaint #11708691, filed 2026-01“After pre warming the car in the garage, I left for work. Three minutes into the drive I heard a single popping sound from the passenger side rear of the car. I then received an error on the dash Stop Vehicle and check power supply . I them drove 4 more miles to work with the hazards on. Two hours later I attempted to drive it to the dealer and it stopped .5 miles away. Hyundai had it towed the rest of the way.”
NHTSA complaint #11714610, filed 2026-01“The ICCU in the car failed. It immediately limited the speed of the vehicle to 25mph. There were no warnings, it happened all at once. I had to drive on the shoulder of the interstate to the next exit. Obviously, driving 25 on the shoulder while cars passed me at 65+ was not a safe situation.”
NHTSA complaint #11671601, filed 2025-07“When in motion, the “EV Start Stop”button is still allowed to turn off the vehicle if accidentally pressed. This happened to me while on the highway and moving about 15-20 MPH. The vehicle suddenly lose power and wouldn’t accelerate. I could not move the vehicle, without hitting the EV Start Stop button several times.”
NHTSA complaint #11535998, filed 2023-08“Even after getting all recalls done my IONIQ5 had an ICCU failure. I feel that latest update which was supposed to fix ICCU issue actually accentuated it. With number of complaints on this car for ICCU failure there should class action law suit on Hyundai”
