NHTSA Complaint #11703111 — 2023 GENESIS GV60

My Genesis EV has experienced multiple incidents where the vehicle suddenly decelerates while driving and limits its speed to approximately 20 mph, creating a significant safety hazard. The first incident occurred in September 2025, when the vehicle unexpectedly began to decelerate on its own and would not exceed ~20 mph. I brought it to the Genesis dealership, but they were unable to reproduce the issue. The second incident occurred in November 2025, with the same failure: sudden deceleration and a maximum speed of ~20 mph. I brought the vehicle back to the dealership. They have kept the car for diagnosis but again report they “cannot reproduce” the problem. The issue remains unresolved, and Genesis has denied my buyback request. This is an intermittent EV drivetrain or power-delivery failure that prevents the vehicle from accelerating normally. If this occurs in traffic, at intersections, or during merging, it could easily lead to a collision. The vehicle is currently still at the dealership because I do not feel safe driving it. Multiple attempts to have the problem repaired have not identified the cause. I am reporting this because sudden loss of acceleration and speed limitation is a major safety issue, and other drivers may experience the same failure.
