Last week while driving with the ICE engaged, check engine light appeared, car shuddered, reduced propulsion message appeared, and a few minutes later OnStar message was Emissions Issue.
Today the dealer service advisor said the problem was the EGR valve. The bigger issue is that he also said there are no Volt EGR valves available in the U.S. He thought GM would have to rebuild a valve and that my wait could be one week to 6 months. Have any of you had similar parts' issues since Volt production ceased? Any suggestions for contacting GM should a week extend to months waiting for a valve?
