While operating my 2023 Chevrolet Corvette at approximately 75 mph on [XXX], the vehicle suddenly and unexpectedly lost propulsion. Moments later, the vehicle completely shut down. The instrument display went dark and the vehicle's lights went out. This occurred in active highway traffic. I struggled to maintain control of the vehicle while avoiding surrounding vehicles and narrowly avoided a potentially catastrophic collision. I managed to bring the Corvette to rest on the shoulder. The vehicle was subsequently transported approximately 20 miles to an authorized Chevrolet dealership at my expense. The dealership retained the vehicle for approximately five months. During that period, I was not provided a courtesy or replacement vehicle. The dealership replaced the transmission under the manufacturer's warranty. The replacement transmission part number may differ from the original, but this requires confirmation from repair records. Although the transmission was replaced, I do not know whether the dealership separately diagnosed and corrected the cause of the complete electrical blackout. I am concerned that the loss of propulsion followed by a complete electrical blackout represents a serious safety defect that could result in a collision, serious injury, or death. I request that NHTSA investigate the failure, including the relationship between the transmission malfunction, loss of propulsion, and electrical shutdown.
