Update: The electronic brain for the transmission has a problem. They are replacing this + the throttle body under the Voltec warranty. Gave me a loaner- new Colorado PU. The Volt (2014) did what it supposed to do. It went into "limp-home" mode and let me get to the dealer- I was still able to do 65 mph. Throttle response was reduced. Once I got to the dealer and shut it down, I restarted it but had no propulsion- which is what is supposed to happen. It will be fixed by EOD tomorrow- 2 days in the dealership. And this was because they didn't have one of the 3 parts needed. Cars has 46,000 miles.
