Owner Narrative

In 2023 & 2025, my vehicle had been brought into the Genesis dealership to complete NHTSA 24V868000 safety recall by receiving a new software (Service Campaigns 907G & 025G). However, despite that, on [XXX], the vehicle's ICCU failed while I was traveling at highway speeds. The ICCU is the primary component that the safety recall was supposed to address, yet it failed anyways. The car suddenly and dangerously reduced propulsion on the freeway, and I had to slowly maneuver the car onto the shoulder where the car then completely lost all propulsion entirely. My family and I were in the car, and our safety was at extreme risk since the car lost propulsion without warning on the freeway and other vehicles had to swerve around us. There was the very real possibility that had I not reacted quickly, that we would have been fully immobilized on the freeway, blocking traffic and creating a real safety hazard for other vehicles. There were no warning lights or any indications that the part was going to fail -- it failed immediately, and only after that did multiple warning messages appeared due to systems downstream of the ICCU failing as a result of the ICCU's failure. The dealership (Genesis of Dublin) confirmed that the failure was specific to the ICCU and the vehicle had its ICCU replaced under the 10 year powertrain warranty. I have documentation proving that the problem was caused by the ICCU's failure. In addition, the ICCU's replacement with an identical ICCU simply means this extremely dangerous hazard can occur again without warning in 1 to 2 years' time, since the replaced ICCU is the same unit that failed before - no updates to the ICCU have been announced by Genesis or its dealerships. I reiterate: the problem persists despite 24V868000 being preventative recalls completed. Recall 907G Completed 10/26/23 Recall 025G Completed 01/13/25 The above mitigations are not enough to fix the problem and avoid a dangerous situation.
