2023 Chevrolet CorvetteRecalls, problems, MPG & safety

“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…”

“While driving normally, I was in the middle of a busy highway/intersection when the vehicle suddenly lost power and came to a complete stop. The vehicle shut itself off without warning, leaving the Corvette disabled in the roadway and causing a complete blockage of the road/intersection. Traffic was actively traveling around me, creating a serious safety hazard and putting both myself and other motorists at risk of a collision. After the vehicle stopped, it would not restart. The instrument cluster displayed a theft-deterrent/immobilizer warning and a lock/security symbol, along with a message stating that there could be a problem with the theft-deterrent system and referring to Immobilizer Operation. The vehicle has full electrical power, but when attempting to start it, it only clicks and the engine does not crank or start. I placed the key fob in the designated backup location as instructed in the owner’s manual, but the vehicle still would not start. The exact failed component has not yet been diagnosed or confirmed. The vehicle is available for inspection. The sudden and unexpected loss of power while I was in the middle of a busy highway/intersection…”

“Vehicle is 2023 Chevrolet Corvette Z06 with about 33000 miles. On XXXI was driving about 65 mph on [XXX] in the left lane with my wife as passenger. On a slight left curve the front brakes applied hard on their own without my input. The car slowed very rapidly. A semi truck in the right lane had to take evasive action to avoid a collision. A similar event happened on XXX with only me in the car at about 45 mph. The front brakes applied on their own in a similar way. I also recall a possible similar event in November or XXX. I am not certain of that earliest date. Since then, it has happened several times more and confirmed by Chevrolet Dealership. Warning symptoms: The tire pressure monitoring system warning light has been on intermittently. The right front tire pressure does not display. The light was on before the March event and is on now. Dealer inspection: The dealer inspected the car on XXX and on later visits. A GM corporate field engineer also inspected the car. They stated they could not duplicate the concern and made no repair. I have since returned the vehicle to the dealership and it has been in their possession since XXX. The vehicle was taken out…”
