Well that doesn't sound normal/correct. If you have a dealer nearby you might want to get that checked.It used to show several green blocks when the 'EV' miles reached '0'. It now never shows a reserve unless the ICE charges it but when that is happening I get only 20 mph.
In this case, one letter makes a huge difference. An 'instant' 20mpg is nothing to worry about if it eventually settles down to 35+mpg.It's been in the shop now for 8 days and they say it is normal because there is no problem codes. by the way that should be 20 mpg. sorry.

As others have stated there should be no green bars left when you reach 0 EV miles. The green bars are not representative of battery state of charge. The green bars are representative of usable energy for EV operation.I'm not really concerned about the 20 mpg but I am concerned that I never have any green bars after the EV miles reach zero.
Green bars can reappear with regen or SOC recalculation after CS begins, but you'll still remain in CS mode.As others have stated there should be no green bars left when you reach 0 EV miles.

It sounds like you are ladling out details in piecemeal. We can only go on what you are telling us.I thank all of you for your feedback but why is the battery suddenly fully depleted when it hasn't been for 18 months driving the same way. Maybe I wasn't clear. I am talking about the battery display on the center console.
This is not normal unless you are possibly referring to the Center Stack display. The driver display will not do this. The Center Stack or Console Display has a Power Flow screen. Depending on what is going on this can change. See pages 5-28 and 5-29 of the manual for various scenarios. However, this is different than the driver display.For 18 months when the 'EV Miles' reached '0' the ICE would come on in 'CS' mode and the 'Battery Display' would still have 3 or 4 blocks still green.
And this is normal. The engine will rev high for a while especially at 75 mph. Eventually if finds a point at which the RPMs are where they need to be.All went well until I reached my destination when the 'Battery Display' went all grey and the ICE went to a very high rpm which put some charge back in the battery display. Ever since then after a full complete charge the 'EV Miles' are normal (around 39) but when it reaches '0' the 'Battery Display' is all grey again and the ICE again goes into a high rpm mode instead of the normal 'CS' mode. All this trip I was driving in 'Normal' mode.
The OP's profile says "United States" for location. I live there too, we must be neighbors! I'd be glad to go for a ride with the OP and explain all and recommend a good GM service department if needed.Where are you located? Maybe a few local Volt buddies could arrange to meet you and take a look at your Volt and situation and compare yours to theirs. That's how Corvette owners deal with odd situations that can't easily be explained in text messages.
