NHTSA complaint #11768943

Owner complaint summary

On two separate occasions, my 2021 Genesis GV80 experienced a sudden loss of motive power while driving on Interstate 75 in Atlanta, Georgia, creating an extreme crash hazard. The first incident occurred on August 3, 2026. While traveling at highway speed in heavy traffic, I attempted to change lanes and pressed the accelerator. The vehicle did not respond — instead of accelerating, it crept along at low speed while surrounding traffic continued at approximately 80 mph. I was nearly struck by multiple vehicles and was only able to avoid a collision by steering back into my lane. The second incident occurred under the same circumstances on I-75 on but I don't recall the exact date. Again, when I attempted to change lanes and accelerate, the vehicle failed to respond and I was nearly hit by fast-moving traffic. Both of these occasions were terrifying. On August 11, 2026, I brought the vehicle to the dealership, where the entire transmission and heater box were replaced (vehicle in shop 29 days). Despite this major repair, the drivability problems continued — the engine RPMs race to 4 and 5 before the transmission shifts gears, and the vehicle drives roughly and feels unresponsive. The vehicle is currently at the dealership for replacement of the electric water pump. I am concerned this vehicle has an unresolved defect affecting acceleration and motive power that could cause a serious crash. The dealer's repairs have not corrected it.
