NHTSA Complaint #11620396 — 2017 CHEVROLET VOLT

In what appears to be (based on Google search) hundreds of Volts have the failure whereby the ERG valve fails, but GM is no longer making the part and has an indefinite date to produce them. When this part fails the engine light comes on the the vehicle is not allowed to go over 45 MPH, creating a safety issue when on highways (I live rural, all all roads are over >=55 MPH). GM is unwilling to trade the car at fair value for a new one, nor willing to provide loaners. So the car can only sit in the garage with no resolution. GM is aware of the issue, nut is unwilling to address.
