I found my round-tuit. I bought the thing almost 2 years ago. So, two questions to start:

1. What does it mean when my diagnostics report says I drove 191 electric miles and -1 gas miles for a total of 190 miles?
I do not think my car sucked CO2 out of the air and re-constructed gasoline, nor do I think I drove a mile in reverse.
I do not understand.

2. Any recommendation for a 2016 dash cover? The light brown reflects in the windshield on bright days making it difficult to see.
Not a clever color choice.

Thank you and hello!

Regards, Bruce

Do a search on dashboard cover for 2016 Chevrolet Volt. Lots of products out there. Make sure that you specify whether or not you have forward collision warning.

-1 gas miles sounds like a glitch in the matrix. Or maybe someone tested hold mode in Reverse :)

It means that the Onstar data got corrupted.

100% accurate data collection and reporting for the Volt has been a topic of discussion since day one. It's complicated and glitches occur. Suggest you just monitor it and see how it looks over "thousands" of miles.

I would suggest joining VoltStats.net. That is another way to capture and display your data. Cheers and happy motoring.

Or, the only gas you used was during EMM (Engine Maintenance Mode). My monthly statement shows a -1 gas miles also, and EMM is the only reason the engine turned on during that period.

-1 mile could be some kind of rounding error. I have see enough immaterial rounding errors in financial accounting software that I would not blink an eye at that one. But I do occasionally get questions from clients who want to know whey there is a one cent difference from their own independent calculations, as if spending time over a one cent difference is worthwhile.

The reflection of the dashboard will almost completely disappear if you wear polarized sunglasses. These glasses will also eliminate dash reflection in any other car you might drive, and improve your driving visual performance in other ways, so are highly recommended.

Definitely agree on the rounding possibility. I do a lot of financial paperwork for my company and for some things we round to the next whole dollar, and others we have to put the exact total. Of course at the end of a week, the two numbers are "off" by a couple dollars due to the rounding errors.

No experience with EMM/FMM so I'm not sure how that may affect the gas mileage calculation but it would make sense as I'm pretty sure when in EMM, the computer doesn't add gas miles since it's just operating the engine to get up to temp and lubricate things and not providing any power to the powertrain for the couple minutes it does operate, or ~1 mile if driving.
