I am currently waiting for dealership to get my replacement battery section in. My 2012 shut down after "propulsion power reduced" message and they diagnosed as bad cells/section.
Mine took a little over two weeks from order to installation of section #1My 2013 volt with 30K mostly electric miles threw a cel in mid Feb. I took it to the dealer 2/20 and found out today, mid March that the battery section is on order but I am 43 in line. The chevy volt factory rep did not know when it would ship. Do you think 3-4 weeks is to be expected?
