I leave my car idle occasionally for an extended period. I set charge to 50% and leave plugged in. Been doing this routine for a while with no issues, so I seldom check iPhone app to confirm SOC. Yesterday I checked for first time in 3 weeks. Vehicle connection error. Not deeply worried, but if something went wrong with charging I'd like to know. Called 800 service number. They had access to car logs as of 2 days ago. Charge OK. They also had all service history. Representative was knowledgeable. Confirmed car offline and needs a reboot. Saw nothing else to cause concern. Checked to make sure I knew reboot process. Who else could do this? The integration of single source maintenance records, connected car, telemetry, logs, and a call center staffed by knowledgeable people with access to your information and no stupid script. I could cite as counter-example my calls to other car companies for support, but I will summarize: they've all been unhelpful and pathetic. It would be hard to ever go back to that.
