NHTSA Complaint #11709253 — 2021 GENESIS G90

My 2021 Genesis G90 has experienced repeated failures of the main infotainment / viewing display system, which has been replaced multiple times by authorized Genesis dealers. Despite these repairs, the defect continues to recur. On December 19, 2025, while the main display was nonfunctional, I was involved in a rear-end collision while proceeding from a stop at a traffic light. During this event, the vehicle did not provide any forward collision warning and did not engage autonomous emergency braking, despite the presence of a vehicle directly in front of me. I am concerned that failure of the main display system or its associated control modules disables, suppresses, or prevents proper operation or driver notification of Advanced Driver Assistance Systems (ADAS), including Forward Collision Warning, Forward Collision-Avoidance Assist, and Autonomous Emergency Braking. Due to the display failure, no visual warnings or system status messages could be seen, and there was no indication that collision-avoidance systems were disabled or degraded. The absence of both warnings and braking intervention raises serious concerns regarding system integration, fault handling, and fail-safe design. This vehicle has undergone multiple unsuccessful repair attempts for the same defect and is currently subject to a formal warranty demand under the Magnuson-Moss Warranty Act. This complaint is submitted to request investigation into whether recurring display failures in the 2021 Genesis G90 can impair ADAS functionality or driver awareness, creating an unreasonable safety risk.
