While driving my 2016 Cadillac Escalade with a6.2L V8 engine on [XXX] near Bristow, Oklahoma at approximately 75 mph, the vehicle suddenly and completely lost power. Without any prior warning or unusual noises, the engine shut down, and I lost power to the dashboard and power steering. This caused the vehicle to decelerate rapidly, making it extremely difficult to control. I managed to steer the vehicle to the shoulder of the highway, narrowly avoiding a collision due to the loss of control. The vehicle could not be restarted. The affected components seem to include the engine, electrical system, and steering. These failures put my safety and the safety of others at significant risk due to the sudden and unexpected loss of vehicle control on a busy highway. The vehicle was towed to the nearest Cadillac dealership for inspection and repair. As of now, the dealership has been unable to determine the cause of the engine failure despite conducting multiple tests and inspections. There were no warning lamps, messages, or other symptoms prior to the failure. The dealership has confirmed the issue but has not identified the root cause. The vehicle remains at the dealership for further diagnostics and is available for inspection upon request. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
