I just got a weird problem with my 2016 Volt. I normally have an EV range of about 42 miles in the winter. About 30 miles into my commute, I realized it said I had 20 miles of range left, which is a bit higher than normal. I didn't think much of it until a little later when I noticed my EV range was now at 82 miles... It said I had only used 4.5kWh when it likely should have been around 12kWh.

It appears that somehow the computer was not counting propulsion on the energy screen and simply tracking regenerating whenever I hit the brakes, making the MPGe skyrocket. Right now it shows the battery as full when it should be roughly 10%. Has anyone run into this before or have any thoughts?

I would take it to the dealer. It sounds like the power management controller is faulty. It could result in your battery being over- or under-charged, so I would have them take a look right away. Of course, it could also just be a communication issue so the display is wrong, but I wouldn't take any risks.

I did not see this message until now, but yesterday I ended up charging it and it did charge the proper amount. It seemed like the latter of your guesses was correct, but I think I will bring it into the shop to have it checked up on.

Fair warning -- don't expect too much (if any) help from the GM people on the board here. They are glorified "social media" people that have basically zero power to do anything. My 2017 has died twice (once on the side of the highway) and they never answered any of the major questions I had concerning the repeated problems I've had.

If you ask them any serious questions, or ask for help beyond their pay grade, all they give you is the exact canned answer they gave you over and over "we are really sorry you had this trouble" "sorry we can't give out any corporate contact information, if you have any questions please direct them to your dealer".

I had 4 tires replaced free at 30k miles due to the help of the Volt Advisors (thank you!). However, if you expect them to be a Volt mechanic/technician that can answer tech questions then you will not be happy. They aren't, were never intended to be, and are not promoted as such.

They got my car towed from Wisconsin to the suburbs of Chicago for free after my car left me stranded on vacation :) Maybe you just have to get the right representative
