NHTSA Complaint #11711508 — 2023 KIA EV6

While driving at normal speed, my Kia EV6 experienced a sudden and complete failure of the ICCU system with zero warning. The vehicle instantly lost all propulsion power and all 12V electrical power, rendering the car uncontrollable and unsafe. I was unable to accelerate, unable to place the vehicle in gear, and unable to activate hazard lights. This occurred despite the vehicle being at approximately 99% battery charge. This failure created an immediate and severe safety hazard, as the vehicle effectively became a dead object in traffic without warning to surrounding drivers. There was no prior alert, no dashboard warning, and no indication of impending failure. This defect is well-documented and pervasive across the Hyundai–Kia–Genesis E-GMP electric vehicle platform and has persisted despite multiple recalls spanning several model years. Kia has acknowledged the issue through recalls but does not have a reliable or permanent fix. Even newer model year vehicles that are claimed to address the issue have experienced the same failure. If this defect occurred in an internal combustion engine vehicle — for example, a random, complete engine shutdown or fuel system failure while driving — it is highly unlikely that regulators would permit the issue to persist across multiple model years without resolution. The fact that this is occurring in an electric vehicle should not lower the safety standard. A sudden total loss of propulsion and electrical power is equally dangerous regardless of drivetrain. Critically, there is no assurance that this failure will not recur, even after replacement of the ICCU or related components. Owners are effectively being returned vehicles that can lose all power again at any time, without warning. It is deeply concerning that this issue remains unresolved after multiple recalls and multiple model years. Continued operation of these vehicles without a verified, permanent fix places the public at ongoing risk.
