So I brought my car for a recall about the recent Reduced Propulsion issue...
First thing that I noticed is that I was wondering how my electric summary got down to zero miles again without recharging when I already logged 34 miles on it before I brought it in. Usually it is only reset to zero if I attained full charge. I didn't mind this.
So when I got home, I plugged it in and attended meeting at nearby house. Then I got a message that my Volt is now fully charge after 4 1/2 hours! What??? It was just 9:00 pm and I was expecting a full recharge by 4:30 am (240 Volt on NEMA 14-50) and have carefully programmed that one to charge during the off-peak rates and it charged at the highest rate!
In short, every time you go for a service, especially the recall, keep in mind that GM service could reset all your settings back to factory settings again!!!
I will make it a habit to recheck my settings after each major service.
And so I checked all the other settings. The oil life was reset to 99% when it was about 89% before the service and they didn't do oil change. I have to painstakingly re-enter our weird weekday and weekend schedules of peak rate, off-peak rate, and mid-peek rates, and also the location based charging. I have to go through to settings to make sure everything is to my liking again.
just a reminder. I lost a difference of $4.65 when my Volt charged at peak rate versus off-peak rate for this lesson.
Am monitoring other weird behaviors after the upgrade, and will let you know. So far, when I precondition the car at 5:30 AM and then drive it at 6:00 AM, my estimated EV range increased by 2 miles more, it didn't do that before.
