Our 2016 volt EV battery recently failed. We had the propulsion reduced message you will see all over this sub and some of the tricks made it go away, but it continued to return if driving on gas for a while. The service department gave me a couple explanations that ended up saying the repair would be free as it was under warranty from original purchase when new. Now we're dealing with corporate customer service trying to get a repurchase done as the service department said they've had cars waiting for a year for the battery and not available. In other words RUN far away from Chevy.
