I got this message a few minutes after the gas generator turned on. Has any body else had this message.
The volt is in the shop. They said there replacing the thermostat heater. I never heard of that. I heard of thermostats but not thermostat heaters. Normally when the car is stopped at a red light or parking, the engine turns off. After I got this message the engine keeps running even when stopped. Also after recharging the battery, it stayed gas mode instead of switching back to electric mode.
