My dealer completed the battery replacement this morning for pick up. Looks like they finished in 2 to 3 days (Excluding Sunday). Hope everyone gets the battery replacement soon.I am in S. Cal. Received a letter from GM about calling a dealer to schedule battery replacement. Called my local dealer and they had 4 battery replacement ahead of me scheduled last week. Dropped off my car last Friday. They said it would take ~1 week to replace the battery and the dealer has scheduled a rental for me during the process.
Hope that helps. Are you in S. Cal?
