I haven't been on the forum for a while, but our HV battery replacement took almost 3 weeks. We got a poor rental but they eventually updated to a Q5. As for service, I would give the Torrance Service Center an A, and everything above them including Customer Care and Roadside Assistance a D-. It's been 1300 miles since our total shutdown in the desert, with no issues since but no DC fast charging since either. The wife takes Luci for her second real road trip this weekend (the first ending in the shutdown in Needles) so likely will see DC fast charging on the way.
