This morning, my ELR asked me if I wanted to start engine maintenance. This seems strange, since the engine has been running quite a bit due to our recent cold weather. My Volt would run engine maintenance only if I had been 100% EV for months.
When I told it to proceed, the engine came on along with a message about what % was complete. My Volt usually completed engine maintenance in a mile or less, taking a minute or so. I drove 5 miles in the ELR and the message showed only 45% complete. Then the engine shut off and went the car back to battery for the remaining 5 miles of my commute.
Can anyone make sense of this?
