Traveling at high speed on major highway and engine stopped. Unable to get car restarted and in fact the instrument panel and information center blanked out. Was forced to have vehicle towed approximately 60 miles to purchasing dealership for diagnosis. Dealer indicates engine is seized and will require replacement. Vehicle has had excellent, verifiable, maintenance record. We have owned this vehicle for approximately 18 months and currently has approximately 62,000 miles. Upon research, I have learned that our vehicle is not the only GM product to have this premature failure.

Driving the vehicle on an interstate highway with the flow of traffic at 70 mph, without warning the engine shut off. This caused loss of speed and loss of power steering, almost causing me to be hit in the rear end twice at highway speeds. There were no warning lights or any instrument indication prior to the failure. After barely being able to get the vehicle into the brakedown lane, the vehicle would not restart. The electronics all worked, there were no warnings or indicator lights but the engine would not start despite multiple attempts by myself and the tow truck driver. The vehicle is currently at the dealership being diagnosed.
The car shifted into neutral while I was driving. I was slowing down to stop at a traffic light when it happened.
