Upon accelerating the vehicle onto a 3 lane road, all warning lights came on in the vehicle. A warning message presented on the dashboard stating "engine power reduction" and then the vehicle shut down completely while moving. The engine shut off and the vehicle would not disengage from park. Vehicle had to be towed from the location. At the dealership, the dealer informed me the engine throttle body and intake tube duct hose should be replaced. He also informed me gm is aware of this issue with the vehicle and has not developed a permanent fix for the issue.
