The vehicle shakes at speeds starting at 68 mph and is extreme at 73 mph. I have taken it in for repairs at the Chevrolet dealership twice and to a tire shop. I fear this could be the start of the term known as the "Death Wobble". Chevrolet is aware of this issue and have issued Technical Service Bulletins relating to shake and vibration complaints. This is a brand new 2025 vehicle. Because this vibration/shake occurs it highway speeds a mechanical failure could cause serious injury or death. I have contacted the manufacturer and they do not wish to address the issues with this vehicle.
