Consumer Description

Car experienced ICCU failure. It tripped my 50A breaker at the fuse panel and damaged my EVSE. Car has been sitting in the shop for 3 weeks with NO eta insight (Dropped car off on Jan 20th, 2026). The service center tells me there are 20 Ioniq5s ahead of me still waiting on ICCU replacement parts. NHTSA and other articles have estimated 2-10% with ICCU failures but the problem appears to be much higher than this! I am very disappointed and hope NHTSA.gov will help us to push Hyundai to find a root cause instead of sweeping it under the table claiming less than "1%" are affected.
