While driving vehicle on the Interstate without warning the engine failed. When this occurred the vehicle was being driven at 65 MHP and a strong vibration began that was felt through the steering wheel. Additionally, the vehicle was in the inside lane and had to be maneuvered to get over and to the shoulder. The vehicle was towed to the dealership that it was purchased from which was approximately 150 miles from the breakdown. Dealer indicates a similar issue which I just read about today regarding a Chevy vehicle recall for bearings/cylinder issue. I am submitting this as I believe this recent recall that was announced may involve more Chevy models than were listed. We have been without the vehicle for over 2 months at this time. We have been informed that there are no engines available. This could also be tied to the other engine issue.
