Section 3 of the Voltec system showed abnormally low voltage, so the battery section was replaced under Voltec warranty. This caused sudden stalling of the vehicle on the highway as it transitioned from EV mode to engine.
21500 mi
Heater didn't work when driving electric. An electric water circulator pump was replaced under warranty.
55000 mi
Cabin heating was virtually non-existent in all-electric mode. Dealer found a software update was due that would address this issue, so they applied the update. The update did seem to fix the issue, but other parts were also faulty, so in the end, this update did not fix my no-heat issue in all-electric mode. The heat stopped working in all-electric mode. Technician diagnosed faulty Heater Coolant Control Module and/or faulty Auxillary Coolant Pump, and replaced both under GM High Voltage Warranty. Ops check good.
